[0034] Figure 1 is a perspective view showing the appearance of an electronic device 100 according to various embodiments of the present disclosure.

[0035] Reference Figure 1 , the electronic device 100 may include a projection lens 101 , a head 103 , a body 105 , a cover 107 , or a connector 130 .

[0036] The electronic device 100 may be any of various types of devices. Specifically, the electronic device 100 may be a projector device that magnifies and projects an image on a wall or a screen, and the projector device may be a liquid crystal display (LCD) projector or a digital light processing (DLP) type projector using a digital micromirror device (DMD).

[0037] In addition, the electronic device 100 may be a home display device or an industrial display device, a lighting device used in daily life, or an audio device including a sound module, or may be implemented as a portable communication device (e.g., a smart phone), a computer device, a portable multimedia device, a wearable device, a home appliance, etc. In addition, the electronic device 100 according to various embodiments of the present disclosure is not limited to the above-mentioned devices, and may be implemented as an electronic device 100 having two or more functions of the above-mentioned devices. For example, the electronic device 100 may be used as a display device, a lighting device, or an audio device by turning off a projector function of the electronic device 100 and turning on a lighting function or a speaker function of the electronic device 100 based on manipulation of a processor, and may be used as an artificial intelligence (AI) speaker by including a microphone or a communication device.

[0038] The projection lens 101 may be arranged on one surface of the body 105 and project light passing through the lens array to the outside of the body 105. The projection lens 101 in various embodiments may be an optical lens coated with low dispersion to reduce chromatic aberration. The projection lens 101 may be a convex lens or a condenser lens, and the projection lens 101 according to various embodiments may adjust the focus by adjusting the positions of the plurality of sub-lenses.

[0039] The head 103 may be coupled to one surface of the body 105 so as to support and protect the projection lens 101. The head 103 may be coupled to the body 105 to swivel within a predetermined angle range based on one surface of the body 105.

[0040] The head 103 may be automatically or manually rotated by a user or a processor to freely adjust the projection angle of the projection lens 101. Alternatively, although not shown in the drawings, the head 103 may be coupled to the body 105 and include a neck extending from the body 105, and the head 103 may be tilted or inclined to adjust the projection angle of the projection lens 101.

[0041] The main body 105 is a housing constituting an exterior appearance, and may support or protect components of the electronic device 100 (eg, Figure 3 The main body 105 may have a Figure 1 However, the shape of the body 105 is not limited thereto, and according to various embodiments of the present disclosure, the body 105 may be implemented in various geometric shapes such as a column having a polygonal cross-section, a cone, or a sphere.

[0042] The body 105 may have a size that enables the body to be grasped or moved by a user with his / her one hand, or may be implemented in a miniature size that enables the body to be easily carried or a size that enables the body to be held on a table or combined with a lighting device.

[0043] The material of the main body 105 may be matte metal or synthetic resin so that the user's fingerprints or dust will not stain the main body. Optionally, the appearance of the main body 105 may be made of a smooth glossy material.

[0044] The body 105 may have a friction area arranged on a partial area of ​​the exterior of the body 105 to be gripped and moved by a user. Optionally, the body 105 may have a folded grip portion or support 108a (see Figure 4 ), which gripping portion or support 108a is arranged in at least a partial area and can be gripped by a user.

[0045] The electronic device 100 can project light or an image to a desired position by adjusting the direction of the head 103 while the position and angle of the body 105 are fixed, and by adjusting the projection angle of the projection lens 101. In addition, the head 103 may include a handle that the user can grasp after rotating the head in a desired direction.

[0046] A plurality of openings may be arranged in the outer circumferential surface of the body 105. Audio output from the audio output unit may be output to the outside of the body 105 of the electronic device 100 through the plurality of openings. The audio output unit may include a speaker, and the speaker may be used for general purposes such as reproduction of multimedia or reproduction of recordings and output of voice.

[0047] According to various embodiments of the present disclosure, the body 105 may include a heat dissipation fan (not shown) disposed therein, and if the heat dissipation fan (not shown) is driven, air or heat in the body 105 may be discharged through the plurality of openings. Therefore, the electronic device 100 may discharge heat generated by driving the electronic device 100 to the outside, and prevent the electronic device 100 from overheating.

[0048] The connector 130 can connect the electronic device 100 to an external device to send or receive electronic signals, or receive power from an external device. The connector 130 according to various embodiments of the present disclosure can be physically connected to an external device. Here, the connector 130 may include an input / output interface to connect the connector 130 to an external device in a wired or wireless manner, or to receive power from an external device. For example, the connector 130 may include a high-definition multimedia interface (HDMI) connection terminal, a universal serial bus (USB) connection terminal, a secure digital (SD) card receiving slot, an audio connection terminal, or a power socket. Optionally, the connector 130 may include a Bluetooth, wireless fidelity (Wi-Fi) or wireless charging connection module that is connected to an external device in a wireless manner.

[0049] In addition, the connector 130 may have a socket structure connected to an external lighting device, and may be connected to a socket receiving groove of the external lighting device to receive power. Considering the receiving structure of the external device that can be coupled to the connector 130, the size and specification of the connector 130 having a socket structure can be implemented in various ways. For example, according to the international standard E26, the diameter of the joint of the connector 130 can be 26 mm, and in this case, the electronic device 100 can be coupled to an external lighting device, such as a bracket that replaces a commonly used light bulb. In addition, in the case of being connected to a socket located on an existing ceiling, the electronic device 100 having a structure that projects an image from the top to the bottom may not be rotated by being coupled to the socket, and in this case, the screen may also not be rotated. Therefore, the electronic device 100 can project or rotate the screen to a desired position while the socket is coupled to the bracket on the ceiling by allowing the head 103 to rotate to the adjusted projection angle on one surface of the body 105, so that the electronic device 100 can rotate even when the socket is coupled and receives power.

[0050] The connector 130 may include a coupling sensor, and the coupling sensor may sense whether the connector 130 and the external device are coupled to each other or their coupling states or coupling targets and transmit it to the processor, and the processor may control the operation of the electronic device 100 based on the received detection value.

[0051] The cover 107 may be coupled to or separated from the body 105, and protect the connector 130 so that the connector 130 is not always exposed to the outside. The cover 107 may have a Figure 1 The shape shown is continued from the shape of the body 105, or may be implemented to correspond to the shape of the connector 130. The cover 107 may support the electronic device 100, and the electronic device 100 may be used by being coupled to an external holder or being held on an external holder while being coupled to the cover 107.

[0052] In the electronic device 100 according to various embodiments, a battery may be disposed within the cover portion 107. The battery may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell.

[0053] Although not shown in the drawings, the electronic device 100 may include a camera module, and the camera module may capture still images and moving images. According to various embodiments, the camera module may include at least one lens, an image sensor, an image signal processor, or a flash.

[0054] Although not shown in the figures, the electronic device 100 may include a protective case (not shown) to protect the electronic device 100 and facilitate transportation of the electronic device 100, or include a bracket (not shown) for supporting or fixing the main body 105, or a bracket (not shown) that can be coupled to a wall or a partition.

[0055] In addition, the electronic device 100 can be connected to various external devices by using the socket structure of the electronic device 100, thereby providing various functions. The electronic device 100 according to various embodiments can be connected to an external camera device by using the socket structure. The electronic device 100 can provide an image stored in a camera device connected to the electronic device 100 or an image currently being captured by using the projection unit 112. In another embodiment, the electronic device 100 can be connected to a battery module using the socket structure and powered. In addition, the electronic device 100 can be connected to an external device using the socket structure, which is only one of the various embodiments, and can be connected to an external device using another interface (e.g., USB).

[0056] Figure 2 is a block diagram illustrating a configuration of an electronic device 100 according to various embodiments of the present disclosure.

[0057] Reference Figure 2 , the electronic device 100 may include at least one processor 111 , a projection unit 112 , a memory 113 , and a communication interface 114 .

[0058] At least one processor 111 may perform overall control operations of the electronic device 100. Specifically, at least one processor 111 may be used to control overall operations of the electronic device 100. Figure 3 A detailed description of at least one processor 111 is provided.

[0059] The projection unit 112 may be a component for projecting an image (eg, a projection image or content) to the outside. Figure 3 A detailed description of the projection unit 112 is provided.

[0060] In addition, in the above, only a brief configuration of configuring the electronic device 100 is shown and described. However, in implementation, various configurations may also be provided. Figure 3 Provide its description.

[0061] Figure 3 is a diagram showing various embodiments according to the present disclosure Figure 2 1 is a block diagram of a detailed configuration of the electronic device 100 shown in FIG.

[0062] Reference Figure 3The electronic device 100 may include at least one of a processor 111, a projection unit 112, a memory 113, a communication interface 114, a manipulation interface 115, an input / output interface 116, a speaker 117, a microphone 118, a power supply unit 119, a driving unit 120, or a sensor unit 121.

[0063] in addition, Figure 3 The configuration shown in is only one of various embodiments, some configurations may be omitted from the configuration, and new configurations may be added to the configuration.

[0064] In addition, the referenced Figure 2 Describe the details.

[0065] The processor 111 may be implemented as a digital signal processor (DSP), a microprocessor, or a time controller (TCON) for processing digital signals. However, the processor 111 is not limited thereto and may include at least one of the following items or may be defined by these terms: a central processing unit (CPU), a microcontroller unit (MCU), a microprocessing unit (MPU), a controller, an application processor (AP), a graphics processing unit (GPU), a communication processor (CP), or an advanced reduced instruction set computer (RISC) machine (ARM) processor. In addition, the processor 111 may be implemented in a system on chip (SoC) or a large-scale integration (LSI) embedded with a processing algorithm, or may be implemented in the form of a field programmable gate array (FPGA). In addition, the processor 111 may perform various functions by executing computer executable instructions stored in the memory 113.

[0066] The projection unit 112 may be a component for projecting an image to the outside. The projection unit 112 according to various embodiments of the present disclosure may be implemented in any of various projection types (e.g., a cathode ray tube (CRT) type, a liquid crystal display (LCD) type, a digital light processing (DLP) type, or a laser type). As an example, the CRT type may have a principle substantially the same as that of a CRT monitor. The CRT type may display an image on a screen by magnifying the image using a lens in front of the cathode ray tube (CRT). The CRT type may be classified into a single tube type and a three-tube type based on the number of cathode ray tubes, and in the three-tube type, the cathode ray tubes of red, green, and blue may be separated from each other.

[0067] As another example, the LCD type can display an image by allowing light emitted from a light source to pass through liquid crystal. The LCD type can be classified into a single-panel type and a three-panel type. In the case of the three-panel type, the light emitted from the light source can be separated into red, green, and blue in a dichroic mirror (which is a mirror that reflects only light of a specific color and allows the rest of the light to pass), then can pass through the liquid crystal, and then can be collected again to one location.

[0068] As another example, the DLP type can display an image by using a digital micromirror device (DMD) chip. The DLP type projection unit may include a light source, a color wheel, a DMD chip, a projection lens, etc. The light emitted from the light source may be colored when passing through a rotating color wheel. The light passing through the color wheel may be input into the DMD chip. The DMD chip may include many micromirrors and reflect the light input into the DMD chip. The projection lens may expand the light reflected from the DMD chip to an image size.

[0069] As yet another example, the laser type may include a diode pumped solid-state (DPSS) laser and a galvanometer. A laser type that outputs various colors may use a laser in which three DPSS lasers are installed for red, green, and blue (RGB) colors, respectively, and the optical axes of the three DPSS lasers overlap each other by using a special mirror. The galvanometer may include a mirror and a high-power motor, and move the mirror at a high speed. For example, the galvanometer may rotate the mirror at a speed of up to 40kHz / sec. The galvanometer may be installed along the scanning direction, and typically, the projector performs a plane scan, and the galvanometer may therefore also be set by being divided into an x-axis and a y-axis.

[0070] In addition, the projection unit 112 may include various types of light sources. For example, the projection unit 112 may include at least one light source of a lamp, a light emitting diode (LED), or a laser.

[0071] The projection unit 112 can output images with a screen ratio of 4:3, a screen ratio of 5:4, and a wide screen ratio of 16:9 based on the purpose of the electronic device 100, user settings, etc., and can output images with various resolutions (such as wide video graphics array WVGA (854×480 pixels), super video graphics array SVGA (800×600 pixels), extended graphics array XGA (1024×768 pixels), wide extended graphics array WXGA (1280×720 pixels), WXGA (1280×800 pixels), super extended graphics array SXGA (1280×1024 pixels), ultra extended graphics array UXGA (1600×1200 pixels), and full high definition HD (1920×1080 pixels)) based on the screen ratio.

[0072] In addition, the projection unit 112 may perform various functions for adjusting the output image under the control of the processor 111. For example, the projection unit 112 may perform a zoom function, a keystone function, a fast-angle (or four-corner) keystone function, a lens shift function, and the like.

[0073] In detail, the projection unit 112 may enlarge or reduce the image based on the distance of the projection unit 112 from the screen (i.e., the projection distance). That is, the projection unit 112 may perform a zoom function based on the distance of the projection unit 112 from the screen. Here, the zoom function may include a hardware method for adjusting the screen size by moving the lens, a software method for adjusting the screen size by cropping the image, and the like. In addition, in the case of performing the zoom function, it is necessary to adjust the focus of the image. For example, the method for adjusting the focus may include a manual focusing method, an electric focusing method, and the like. The manual focusing method may indicate a method for manually adjusting the focus, and the electric focusing method may indicate a method in which the projector automatically adjusts the focus by using a motor built therein when performing the zoom function. In the case of performing the zoom function, the projection unit 112 may provide a digital zoom function through software, and may provide an optical zoom function for performing the zoom function by moving the lens using the drive unit 120.

[0074] In addition, the projection unit 112 may perform a keystone correction function. If the height does not match the front projection, the screen may be distorted upward or downward. The keystone correction function may be a function of correcting a distorted screen. For example, when the screen is distorted in the horizontal direction, horizontal keystone may be used to correct the distortion, and when the screen is distorted in the vertical direction, vertical keystone may be used to correct the distortion. The fast corner (or four-corner) keystone correction function may be a function of correcting the screen when the balance between the corner areas of the screen is not appropriate while the center area of ​​the screen is normal. The lens shift function may be a function of moving the picture as it is when the picture is outside the screen.

[0075] In addition, the projection unit 112 can provide zoom / keystone / focus functions by automatically analyzing the surrounding environment and the projection environment without user input. In detail, the projection unit 112 can automatically provide zoom / keystone / focus functions based on the distance between the electronic device 100 and the screen detected by a sensor (e.g., a depth camera, a distance sensor, an infrared sensor, or a light sensor), information about the space where the electronic device 100 is currently located, information about the amount of ambient light, etc.

[0076] In addition, the projection unit 112 may provide a lighting function by using a light source. Specifically, the projection unit 112 may provide a lighting function by outputting a light source using an LED. In various embodiments, the projection unit 112 may include one LED, and in another embodiment, the electronic device 100 may include a plurality of LEDs. In addition, in an implementation example, the projection unit 112 may output a light source by using a surface-emitting LED. Here, the surface-emitting LED may be an LED in which an optical sheet is arranged on the upper side of the LED to evenly disperse and output the light source. In detail, in the case of output through the LED, the light source may be evenly dispersed by the optical sheet, and the light source dispersed by the optical sheet may be incident on the display panel.

[0077] In addition, the projection unit 112 may provide a dimming function for adjusting the intensity of the light source to the user. Specifically, when a user input for adjusting the intensity of the light source is received from the user through the manipulation interface 115 (e.g., touching a display button or a dial), the projection unit 112 may control the LED to output the intensity of the light source corresponding to the received user input.

[0078] In addition, the projection unit 112 may provide a dimming function without user input based on the content analyzed by the processor 111. In detail, the projection unit 112 may control the LED to output the light source of the intensity based on information about the currently provided content (eg, content type or content brightness).

[0079] In addition, the projection unit 112 may control the color temperature under the control of the processor 111. Here, the processor 111 may control the color temperature based on the content. In detail, if the content to be output is identified, the processor 111 may obtain color information for each frame of the content determined to be output. Then, the processor 111 may control the color temperature based on the obtained color information for each frame. Here, the processor 111 may obtain at least one main color of the frame based on the color information for each frame. Then, the processor 111 may control the color temperature based on the obtained at least one main color. For example, the color temperature adjustable by the processor 111 may be classified as a warm color type or a cold color type. Here, it may be assumed that the frame to be output (hereinafter, the output frame) includes a fire scene. The processor 111 may identify (or obtain) that the main color is red based on the color information included in the current output frame. Then, the processor 111 may identify the color temperature corresponding to the identified main color (red). Here, the color temperature corresponding to red may be a warm color type. In addition, the processor 111 may use an artificial intelligence model to obtain the color information or main color of the frame. In various embodiments, the artificial intelligence model may be stored in the electronic device 100 (eg, the memory 113). In another embodiment, the artificial intelligence model may be stored in an external server that can communicate with the electronic device 100.

[0080] The memory 113 may be implemented as an internal memory included in the processor 111, such as a read-only memory (ROM, for example, an electrically erasable programmable read-only memory (EEPROM)) or a random access memory (RAM), or may be implemented as a memory separate from the processor 111. In this case, based on the data storage purpose, the memory 113 may be implemented in the form of a memory embedded in the electronic device 100 or in the form of a memory detachable from the electronic device 100. For example, data for driving the electronic device 100 may be stored in the memory embedded in the electronic device 100, and data for extended functions of the electronic device 100 may be stored in the memory detachable from the electronic device 100.

[0081] In addition, the memory embedded in the electronic device 100 can be implemented as a volatile memory (for example, dynamic RAM (DRAM), static RAM (SRAM) or synchronous dynamic RAM (SDRAM)) or a non-volatile memory (for example, a one-time programmable ROM (OTPROM), a programmable ROM (PROM), an erasable programmable ROM (EPROM), an electrically erasable programmable ROM (EEPROM), a mask ROM, a flash ROM, a flash memory (for example, a NAND flash memory or a NOR flash memory), a hard disk drive or a solid-state drive (SSD), and the memory removable from the electronic device 100 can be implemented as a memory card (for example, compact flash (CF), secure digital (SD)), micro secure digital (Micro-SD), mini secure digital (mini-SD), extreme digital (xD) or multimedia card (MMC)), or an external memory connectable to a universal serial bus (USB) port (for example, a USB memory), etc.

[0082] The memory 113 may store at least one instruction in the electronic device 100. In addition, the memory 113 may store an operating system (O / S) for driving the electronic device 100.

[0161] Reference Figure 8 In the embodiment 810, the electronic device 100 may include a support (or "base") 108e.

[0162] The support 108e in various embodiments may include a base plate 108e-1 and two support members 108e-2 configured to support the electronic device 100 on the ground. Here, the two support members 108e-2 may connect the base plate 108e-1 and the body 105 to each other.

[0163] In various embodiments of the present disclosure, the two support members 108e-2 may have the same height, and therefore, each cross-section of the two support members 108e-2 may be combined or separated by grooves and hinge members (not shown) arranged on the outer circumferential surface of the body 105.

[0164] Each of the two supporting members may be hingedly connected to the main body 105 at a predetermined point on the main body 105 (eg, 1 / 3 to 2 / 4 of the height of the main body).

[0165] If the two supporting members and the body are coupled to each other through a hinge member (not shown), the body 105 may rotate about an imaginary horizontal axis formed by the two hinge members (not shown), thereby adjusting a projection angle of the projection lens 101 .

[0168] in addition, Figure 4 , Figure 5 , Figure 6 , Figure 7 or Figure 8 The support member shown in FIG. 1 is only one of various embodiments, and the electronic device 100 may have a support member in any of various positions or shapes.

[0169] Fig. 9 is a perspective view showing the appearance of an electronic device 100 according to various embodiments of the present disclosure.

[0170] Reference Fig. 9 In the embodiment 910, the electronic device 100 may include a moving member 109. The moving member 109 may indicate a member for performing the following operation: moving the electronic device 100 from a first position to a second position in a space where the electronic device 100 is arranged. The electronic device 100 may control the moving member 109 to move the electronic device 100 by using the force generated by the driving unit 120.

[0171] Fig. 9Embodiment 920 in the embodiment 910 may be a diagram of the electronic device 100 observed from a different direction.

[0172] In addition, detailed operations of the processor 111 according to the present disclosure may be described using the following drawings.

[0173] The processor 111 may recognize the projection surface using the sensor unit 121 .

[0174] For details, refer to Fig.10 , the processor 111 may obtain information about the surrounding environment of the electronic device 100 using the sensor unit 121 (S1010).

[0175] In addition, the processor 111 may identify at least one projection surface candidate based on information about the surrounding environment of the electronic device 100 (S1020). Fig.11 As shown, the processor 111 may identify a region of the wall 10 surrounding the electronic device 100 excluding the obstacles 11 , 12 , and 13 as one or more projection surface candidates 20 and 21 .

[0176] In addition, if one or more projection surface candidates are identified, the processor 111 may identify one projection surface candidate among the one or more projection surface candidates as a projection surface on which the projection image is projected ( S1030 ).

[0177] For example, the processor 111 may obtain a user input for selecting one of the one or more projection surface candidates. In addition, the processor 111 may identify the projection surface candidate selected from the one or more projection surface candidates as the projection surface.

[0178] Optionally, the processor 111 may identify one of the one or more projection surface candidates as the projection surface based on a color, a curvature, a size, or a ratio of the one or more projection surface candidates.

[0179] In detail, the processor 111 may identify a projection surface candidate whose horizontal length is a predetermined value (e.g., 1 m) or longer as a projection surface. Alternatively, the processor 111 may identify a projection surface candidate whose color is a solid color other than black and similar to white as a projection surface candidate. Alternatively, the processor 111 may identify a projection surface candidate whose ratio of vertical length to horizontal length is a predetermined value (4:1, 1:4, or 16:9) or is close to the predetermined value as a projection surface candidate.

[0180] In addition, the processor 111 may obtain information about the projection surface using the sensor unit 121 (S1040). In detail, the processor 111 may obtain information about the projection surface using an image sensor, a depth sensor, or a distance sensor. Here, the information about the projection surface may include at least one of a ratio of the projection surface, a horizontal length of the projection surface, or a vertical length of the projection surface.

[0181] In addition, the processor 111 may identify whether the ratio of the projection surface is different from the ratio of the image to be projected on the projection surface.

[0182] Here, the image may indicate an image to be projected on the projection surface. In addition, the image may be stored in the memory 113, received from an external device through the communication interface 114, or obtained through an input / output interface.

[0183] In addition, in the present disclosure, the ratio may indicate the ratio of the vertical length to the horizontal length or the ratio of the vertical length to the horizontal length. For example, the ratio of the projection surface may indicate the ratio of the vertical length to the horizontal length of the projection surface. Alternatively, the ratio of the image may indicate the ratio of the vertical length to the horizontal length of the image. Alternatively, the ratio of the region of interest may indicate the ratio of the vertical length of the region of interest to the horizontal length of the region of interest.

[0184] If the ratio of the projection surface is the same as the ratio of the image, the processor 111 may project the image on the projection surface without cropping the image.

[0185] In addition, if the projection surface and the image have different ratios, the processor 111 may obtain a projection image by cutting out a portion of the image, and project the obtained projection image on the recognized projection surface. Fig.12 A detailed method in which the processor 111 obtains a projection image by cutting out a portion of an image is described.

[0186] Reference Fig.12 , the processor 111 may obtain information about the projection surface (S1210). In addition, the processor 111 may identify a first region of interest (ROI) in the image (S1220).

[0187] In detail, the processor 111 may obtain a saliency map of the image. Here, the saliency map may indicate a map representing a saliency value for each pixel of the projected image. In addition, the saliency value may indicate the probability that each pixel of the image belongs to an object of interest or a region of interest.

[0188] In addition, the processor 111 may identify a first region of interest in the image based on the saliency map. Here, the processor 111 may identify a region in the saliency map where a saliency value is concentrated and has a predetermined saliency value (e.g., 0.6) or greater as the first region of interest. Here, the first region of interest may be a region including an object of interest.

[0189] For example, Fig.13a As shown, the processor 111 may identify a region in the image 30 where saliency values ​​having a predetermined saliency value or greater are concentrated as the first region of interest 40. Here, the first region of interest 40 may be a region including the sun as an object of interest.

[0190] In addition, in the present disclosure, the size of the region of interest may be changed based on the saliency value used to identify the region of interest. Fig.13b , the processor 111 may identify the region of interest 40 having a first size based on a first significance value (e.g., 0.6). In addition, the processor may identify the region of interest 41 having a second size smaller than the first size based on a second significance value (e.g., 0.4) smaller than the first significance value. In addition, the processor 111 may identify the region of interest 42 having a third size larger than the first size based on a third significance value (e.g., 0.8) larger than the first significance value.

[0191] In addition, according to an embodiment of the present disclosure, the processor 111 may identify a plurality of regions of interest, and identify a first region of interest based on a user input for selecting the first region of interest from among the plurality of regions of interest.

[0192] In detail, Fig.13c As shown, the processor 111 can identify multiple regions of interest 43a, 43b and 43c, control the display to display the multiple regions of interest 43a, 43b and 43c together with at least a portion of the image 30 on the display, or control the projection unit 112 to display the multiple regions of interest 43a, 43b and 43c on the projection surface.

[0193] Here, the processor 111 may also display identification information 47, 48 or 49 for each of the plurality of interest regions 43a, 43b, 43c. Fig.13c As shown, identification information 44a, 44b or 44c for each of the plurality of interest regions 43a, 43b and 43c may be displayed as numbers such as 1, 2 and 3, which is only an embodiment, and the plurality of interest regions may be displayed in various forms.

[0194] In addition, the processor 111 may obtain a user input for selecting one of the plurality of interest regions 43a, 43b, and 43c through the manipulation interface 115, the microphone 118, or the camera module.

[0195] For example, the processor 111 may obtain a user input for selecting one of the plurality of interest regions 43a, 43b, and 43c through a physical button included in the manipulation interface 115, such as an arrow key (eg, up, down, or left and right arrow keys).

[0196] Optionally, the processor 111 may obtain a user voice input for selecting a specific region of interest from the multiple regions of interest 43a, 43b, and 43c through the microphone 118. Here, the user voice may be a voice including identification information corresponding to the specific region of interest. For example, the user voice input for selecting a specific region of interest from the multiple regions of interest 43a, 43b, and 43c may be "select region of interest 1" or "select region 1".

[0197] Optionally, the processor 111 may detect a user gesture for selecting a specific region of interest from the multiple regions of interest 43a, 43b, and 43c through the camera module. For example, the user gesture for selecting a specific region of interest from the multiple regions of interest 43a, 43b, and 43c may be a gesture of pointing a finger at the specific region of interest.

[0198] In addition, if a specific region of interest is selected from the plurality of regions of interest 43a, 43b, 43c, the processor 111 may identify the selected specific region of interest as the first region of interest.

[0199] In addition, if the first region of interest is identified, the processor 111 may obtain a projection image by cropping a portion of the image to include at least a portion of the first region of interest (S1230). Here, the projection image may indicate a remaining image of the image excluding the cropped portion.

[0200] In addition, the processor 111 may obtain a projected image by cropping a portion of the image to include at least a portion of the first region of interest based on the information about the projection surface and the information about the first region of interest.

[0201] According to an embodiment of the present disclosure, the processor 111 may obtain the projection image by cropping a portion of the image so that at least a portion of the first region of interest is included in the projection image.

[0202] Here, the processor 111 may obtain the projection image by cropping a portion of the image so that the ratio of the projection image is the same as the ratio of the projection surface.

[0203] For details, refer to Fig.14 If a first region of interest in the image is identified (S1410), the processor 111 may identify whether a ratio of a vertical length of the first region of interest to a horizontal length of the image is the same as a ratio of a vertical length of the projection surface to a horizontal length of the projection surface (S1420).

[0204] If the ratio of the vertical length of the first region of interest to the horizontal length of the image and the ratio of the vertical length of the projection plane to the horizontal length of the projection plane are not the same (S1420-No), the processor 111 may identify a second region of interest included in the first region of interest (S1430). Here, the second region of interest may be a region corresponding to the ratio of the projection plane and the horizontal length of the image.

[0205] In detail, the processor 111 may identify the second region of interest so that a ratio of a vertical length of the second region of interest to a horizontal length of the image and a ratio of the projection surface are the same.

[0206] For example, Fig.15a As shown, the horizontal length of the image 30 may be W2, and the vertical length of the image 30 may be H2. In addition, the horizontal length of the first region of interest 40 may be W1, and the vertical length of the first region of interest 40 may be H1. In addition, the horizontal length of the projection plane 20 may be PW, and the vertical length of the projection plane may be PH.

[0207] Here, the ratio of H2 to W1 may be different from the ratio of PH to PW. Here, the processor 111 may identify the second region of interest 41 included in the first region of interest 40. In detail, the processor 111 may identify the second region of interest 41 so that the ratio of the vertical length H3 of the second region of interest 41 to the horizontal length W2 of the image 30 and the ratio of the projection surface 20 (the ratio of PH to PW) are the same.

[0208] Here, the processor 111 may adjust the size of the second region of interest 41 by adjusting the significance value for identifying the region of interest. In detail, the processor 111 may reduce the significance value to be less than a predetermined value so that the height of the second region of interest 41 is lower than that of the first region of interest. In addition, the processor 111 may identify the second region of interest by using a significance value for making the ratio of the vertical length of the second region of interest to the horizontal length of the image the same as the ratio of the projection surface.

[0209] In addition, the processor 111 may identify the first region of interest based on a saliency value corresponding to the ratio of the projection surface and the horizontal length of the image. In detail, the memory 113 may store values ​​for saliency values ​​corresponding to the ratio of the projection surface and the horizontal length of the image in the form of a lookup table, and the processor 111 may obtain a saliency value corresponding to the projection surface. In addition, the processor 111 may identify the first region of interest in the image by using the saliency value corresponding to the projection surface.

[0210] In addition, if the second region of interest is identified, the processor 111 may obtain a projection image by cropping a portion of the image to include the entire second region of interest (S1440).

[0211] In detail, if the second region of interest is identified, the processor 111 may obtain a projected image by cropping a region in the image having a height different from that of the second region of interest. Here, the projected image may include the entire second region of interest. That is, the processor 111 may obtain a projected image by maintaining the horizontal length of the image and cropping the image 30 so that the vertical length of the image is the same as that of the second region of interest.

[0212] For example, Fig.15b As shown, the processor 111 may identify a region 50 in the image 30 having a height different from that of the second region of interest 41. In addition, the processor 111 may also obtain the projection image 31 by cutting out the region 50 in the image 30 having a height different from that of the second region of interest 41. Here, the projection image 31a may include a portion of the first region of interest 40 and the entire second region of interest 41. In addition, the horizontal length of the projection image 31a may be the same as the horizontal length of the image 30, and the vertical length of the projection image 31a may be the same as the vertical length of the second region of interest 41.

[0213] In addition, if the ratio of the vertical length of the first region of interest to the horizontal length of the image and the ratio of the vertical length of the projection surface to the horizontal length of the projection surface are the same (S1420-Yes), the processor 111 can obtain a projected image by cropping the image to include the entire first region of interest (S1450).

[0214] For example, Fig.16a As shown, the horizontal length of the image 30a may be W2a, and the vertical length of the image 30a may be H2a. In addition, the horizontal length of the first region of interest 40a may be W1a, and the vertical length of the first region of interest 40a may be H1a. In addition, the horizontal length of the projection plane 20 may be PW, and the vertical length of the projection plane may be PH. In addition, the ratio of H1a to W2a may be the same as the ratio of PH to PW.

[0215] Here, if Fig.16b As shown, the processor 111 can obtain the projection image 31a by cutting the region 50a having a height different from that of the first region of interest 40a in the image 30a. Here, the projection image 31a can have the same horizontal length as that of the image 30a, and the same vertical length as that of the first region of interest 40a.

[0216] In addition, if Fig.16c As shown, the processor 111 may project the projection image 31 a onto the projection surface 20 .

[0217] According to an embodiment of the present disclosure, the processor 111 may obtain a projection image by cropping a portion of the image so that the entire first region of interest is included in the projection image.

[0218] Here, the processor 111 may obtain the projected image by cropping a portion of the image so that the ratio of the vertical length to the horizontal length of the projected image is the ratio of the vertical length to the horizontal length of the projection surface or greater. Alternatively, the processor 111 may obtain the projected image by cropping a portion of the image so that the ratio of the vertical length of the first region of interest to the horizontal length of the projected image is the ratio of the vertical length to the horizontal length of the projection surface or greater.

[0219] For details, refer to Fig.17 If a first region of interest in the image is identified (S1710), the processor 111 may obtain a first cropped image by cropping a region in the image having a height different from that of the first region of interest (S1720).

[0220] For example, Fig.18a As shown, if the first region of interest 40 in the image 30 is identified, the processor 111 may obtain a first cropped image 32 by cropping a region 51 in the image 30 having a height different from that of the first region of interest 40 .

[0221] In addition, the processor 111 may compare the ratio of the first crop image with the ratio of the projection surface. In detail, the processor 111 may identify whether the ratio of the vertical length to the horizontal length of the first crop image is the ratio of the vertical length to the horizontal length of the projection surface or more (S1730).

[0222] In addition, if the ratio of the vertical length to the horizontal length of the first cropped image is the ratio of the vertical length to the horizontal length of the projection surface or more (S1730-No), the processor 111 may project the first cropped image as a projection image on the projection surface (S1740). Here, the vertical length of the first cropped image may be the vertical length of the first region of interest.

[0223] For example, Fig.18b As shown in FIG. 1 , if the ratio H1 / W2 of the vertical length to the horizontal length of the first cropped image 32 is the ratio PH / PW of the vertical length PH to the horizontal length PW of the projection surface 20 or greater, then Fig.18c As shown, the processor 111 may project the first cropped image 32 onto the projection surface 20 .

[0224] In addition, here, the processor 111 may not project any light onto the area 23 or 24 of the projection surface 20, project light of a specific color onto the area 23 or 24 of the projection surface 20, or project a widget image onto the area 23 or 24 of the projection surface 20, wherein the first cropped image 32 as the projection image is not projected into the area 23 or 24 of the projection surface 20.

[0225] For example, Fig.18d As shown, the processor 111 may project black light onto the left area 23 and the right area 24 in the first cropped image 32. Therefore, the electronic device 100 may provide the user with an immersive experience of the image projected on the projection surface 20.

[0226] Optionally, the processor 111 may project the widget image onto the left area 23 or the right area 24 in the first cropped image 32. Here, the widget image may include an object such as a clock. Fig.18e As shown, the processor 111 may project the widget image 25 including the clock object onto the right area 24 in the first cropped image 32 .

[0227] In addition, if the ratio of the vertical length to the horizontal length of the first cropped image is less than the ratio of the vertical length to the horizontal length of the projection surface (S1730-Yes), the processor 111 may obtain the second cropped image by cropping a portion of the first cropped image (S1750). In detail, the processor 111 may obtain the second cropped image by cropping a portion of the first cropped image so that the ratio of the vertical length of the first region of interest to the horizontal length of the second cropped image and the ratio of the vertical length PH to the horizontal length PW of the projection surface 20 are the same.

[0228] For example, Fig.19a As shown, the processor 111 may identify the first region of interest 43 in the image 33. In addition, the processor 111 may obtain the first cropped image 34 by cropping a region 52 or 53 having a height different from that of the first region of interest 43 in the image 33.

[0229] In addition, if Fig.19bAs shown, the ratio of the vertical length H5 to the horizontal length W4 of the first cropped image may be smaller than the ratio of the vertical length PH to the horizontal length PW of the projection surface 20. Here, the processor 111 may obtain the second cropped image 35 by cropping a portion of the first cropped image 34. In detail, the processor 111 may obtain the second cropped image 35 by cropping the first cropped image 34 so that the ratio of the vertical length H5 to the horizontal length W6 of the second cropped image 35 and the ratio of the vertical length PH to the horizontal length PW of the projection surface 20 are the same.

[0230] In addition, if Fig.19c As shown, the processor 111 may project the second cropped image 35 onto the projection surface 20 .

[0231] In addition, according to an embodiment of the present disclosure, the processor 111 may identify multiple candidate cropping regions, and obtain a projection image by cropping a portion of the image based on a user input for selecting a cropping region from the multiple candidate cropping regions. Here, the cropping region may indicate an area in the image that the user wants to crop out.

[0232] In detail, Fig. 20 As shown, the processor 111 may identify multiple candidate cropping regions 45a, 45b, and 45c based on the identified first region of interest 40. Here, each of the multiple candidate cropping regions 45a, 45b, and 45c may be a region including at least a portion of the first region of interest 40.

[0233] In addition, the processor 111 may control the display to display the identified multiple candidate cropping areas 45a, 45b, and 45c, or control the projection unit 112 to display the multiple candidate cropping areas 45a, 45b, and 45c on the projection surface. Here, the processor 111 may control the projection unit 112 to display identification information 46a, 46b, or 46c of each of the identified multiple candidate cropping areas 45a, 45b, and 45c.

[0234] In addition, the processor 111 may obtain a user input for selecting a specific region from among the plurality of candidate cropping regions 45a, 45b, and 45c through the manipulation interface 115, the microphone 118, or the camera module. Here, the selected specific region may be a cropping region.

[0235] For example, the processor 111 may obtain user input for selecting a specific area from among multiple candidate cropping areas 45a, 45b, and 45c through a physical button included in the manipulation interface 115, such as an arrow key (e.g., a down arrow key, a left arrow key, a right arrow key, or a right arrow key).

[0236] Optionally, the processor 111 may obtain a user voice input for selecting a specific area from the plurality of candidate cropping areas 45a, 45b, and 45c through the microphone 118. Here, the user voice may be a voice including identification information corresponding to the specific area. For example, the user voice input for selecting a specific area from the plurality of candidate cropping areas may be "select candidate cropping area 1" or "select area 1".

[0237] Optionally, the processor 111 may detect a user gesture for selecting a specific region from a plurality of candidate cropping regions through a camera module. For example, the user gesture for selecting a specific region from a plurality of candidate cropping regions may be a gesture of pointing a finger at the cropping region.

[0238] In addition, if a specific area is selected as a crop area from among a plurality of candidate crop areas, the processor 111 may obtain a projected image by cropping a portion of the image to include the crop area.

[0239] In addition, according to an embodiment of the present disclosure, the processor 111 may identify a projection surface, obtain a projection image by cropping an image, and project the projection image on the projection surface. Here, if the image is projected on the projection surface, the processor 111 may store projection history information of the image projected on the projection surface in the memory 113. Here, the projection history information may be information stored by matching a setting value for projecting an image on the projection surface with the projection surface.

[0240] Therefore, if the projection surface is re-recognized, the processor 111 may project the image on the re-recognized projection surface based on the projection history.

[0241] In detail, the processor 111 may project the image on the re-identified projection surface by using a pre-stored setting value. Here, the setting value may indicate a setting value for projecting the image on the projection surface. In detail, the setting value may include a saliency value for identifying a first region of interest in the image, a saliency value for identifying a second region of interest, information about a cropping area, information about a cropping position, information about a cropping ratio, information about a projection position, information about projection light (e.g., projecting a black light on an area where the image of the projection surface is not projected), information about a projection widget, or information about a projected image (e.g., a ratio of a projected image or a size of a projected image).

[0242] That is, the electronic device 100 may sense the surrounding environment of the electronic device 100, and if a predetermined projection surface is recognized, the electronic device 100 may project an image on the predetermined projection surface.

[0243] Reference Fig.21 A to Fig.21D describes a method for the electronic device 100 to re-recognize a projection surface by using pre-stored setting values ​​and project an image on the projection surface.

[0244] For details, refer to Fig.21 A, the processor 111 may sense the surrounding environment of the electronic device 100 using the sensor unit 121 (S2110).

[0245] In addition, the processor 111 may identify one or more projection surface candidates based on information about the surrounding environment of the electronic device 100 ( S2120 ).

[0246] In addition, the processor 111 may identify whether there is a projection surface pre-stored in the memory 113 among the one or more projection surface candidates ( S2130 ).

[0247] In detail, the memory 113 may store information about the pre-recognized projection surface. Here, the information about the pre-recognized projection surface may include information about feature points of the pre-recognized projection surface image.

[0248] Here, the processor 111 can identify whether there is a pre-identified projection surface among one or more projection surface candidates by extracting feature points from images of one or more projection surface candidates obtained via an image sensor and comparing the extracted feature points with information about feature points of the pre-identified projection surface.

[0249] In addition, if there is no pre-identified projection surface in the one or more projection surface candidates (S2130-No), the processor 111 may identify one of the one or more projection surface candidates as the projection surface on which the image is projected (S2140). Here, the method in which the processor 111 identifies one of the one or more projection surface candidates as the projection surface is as described above.

[0250] In addition, if there is a pre-recognized projection surface among the one or more projection surface candidates ( S2130 -Y), the processor 111 may recognize the pre-recognized projection surface as a projection surface on which an image is to be projected ( S2150 ).

[0251] In addition, the processor 111 may project the image on the projection surface based on the settings matched with the pre-recognized projection surface and stored in the memory 113 (S2160).

[0252] In detail, the processor 111 may project the image on the projection surface in the same position, shape, or size as the image previously projected on the pre-recognized projection surface.

[0253] In addition, if there is a pre-recognized projection surface among one or more projection surface candidates, an obstacle may be arranged between the electronic device 100 and the projection surface 20. In this case, the electronic device 100 may move to a position where the electronic device 100 can project an image on the projection surface 20 without an obstacle being arranged between the electronic device 100 and the projection surface 20. If the movement is completed, the electronic device 100 may project the image on the pre-recognized projection surface.

[0254] For example, Fig.22a As shown, the electronic device 100 may project the projection image 32 and the clock widget image 25 on the projection surface 20 at the first position. In addition, the electronic device 100 may store the projection history information in the memory 113. Here, the projection history may be the history of the electronic device 100 projecting the projection image 32 and the clock widget image 25 on the projection surface 20 at the first position. In addition, the projection history information may include information about the setting values ​​used by the electronic device 100 to project the projection image 32 and the clock widget image 25 on the projection surface 20 at the first position.

[0255] Then, the electronic device 100 may identify one or more projection surface candidates, and may identify the pre-identified projection surface 20 from among the one or more projection surface candidates 20 and 21. Here, Figure 22b As shown, if the obstacle 14 is arranged between the electronic device 100 and the projection surface 20 , the electronic device 100 may not be able to project an image on the projection surface 20 .

[0256] To solve this problem, Fig.22c As shown, the electronic device 100 may move to a second position where there is no obstacle 14 between the electronic device 100 and the projection surface 20 , and project the projection image 32 and the clock widget image 25 on the projection surface 20 by using the setting values ​​stored in the memory 113 .

[0257] In addition, the electronic device 100 may project a projection image obtained by cropping an image on the projection surface, or project an uncropped image on the projection surface.

[0258] According to an embodiment of the present disclosure, the electronic device 100 may determine whether to crop an image based on an image type. Here, the image type may indicate an image obtained from an external server or an image obtained from a user terminal device.

[0259] For details, refer to Fig.23 , the processor 111 may obtain information about the image (S2310). Here, the processor 111 may obtain information about the image from a content provider, or obtain information about the image from a user.

[0260] In detail, the processor 111 may obtain information about the image provided by the content provider from the external server. In addition, the processor 111 may also obtain information about the image provided by the user from the user terminal device.

[0261] In addition, the processor 111 may identify whether the obtained image is received from an external server (S2320).

[0262] If the image is not received from an external server (S2320-No), that is, if the image is received from a user terminal device, the processor 111 may obtain a projection image by cutting a portion of the image, and project the obtained projection image on a projection surface (S2330). Here, the method in which the processor 111 cuts a portion of the image may be the same as the above method.

[0263] In addition, in a case where the image is received from the external server (S2320-Y), the processor 111 may identify whether a user command for cropping the image is obtained (S2340).

[0264] In detail, the processor 111 may control the speaker 117 to output a voice asking whether to crop an image, or control the projection unit 112 to output a UI asking whether to crop an image.

[0265] In addition, the processor 111 may also obtain a user command regarding whether to crop an image. Here, the user command may be a user command for cropping an image and projecting the cropped image, or a user command for projecting an uncropped image.

[0266] Therefore, in the case where a user command for cropping an image is obtained (S2340-Y), the processor 111 may obtain a projection image by cropping a portion of the image, and project the obtained projection image on the projection surface (S2330).

[0267] In addition, in the case where a user command for not cropping the image is obtained (S2340-N), the processor 111 may project the uncropped image on the projection surface (S2350).

[0268] Here, the processor 111 may project the image so that the center of the uncropped image is arranged at the center of the projection surface where the center is identified. Optionally, the processor 111 may identify a region of interest in the uncropped image and project the image so that the center of the region of interest is arranged at the center of the projection surface where the center is identified.
