[0052] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0053] [Printing System]

[0054] Figure 1 This is a diagram illustrating an example of the system structure of a system for printing images using the printer of this embodiment.

[0055] The printer 10 in this embodiment is configured as a portable mobile printer, and receives images to be printed from an external device indefinitely, printing them onto a medium. The medium used is a sheet-type (also known as a single-sheet type) instant film 12.

[0056] External devices 100 consist of mobile computers with communication capabilities, especially smartphones, tablets, laptops, PDAs (personal data assistants), and mobile phones. Additionally, Figure 1 This example shows an external device that is a smartphone.

[0057] The printer 10 communicates with external devices, for example, according to short-range wireless communication standards such as NFC (Near Field Communication), BLUETOOTH (registered trademark), and WiFi (Wireless Fidelity).

[0058] [Printer's appearance and structure]

[0059] Figure 2 This is a front perspective view showing an example of the external structure of the printer according to this embodiment. Figure 3 yes Figure 2 The image shows a 3D view of the back of the printer.

[0060] As described above, printer 10 is composed of an instant printer (a printer that prints on instant film). Instant film 12 is a film packaging box (see reference) that houses multiple sheets of instant film within a housing. Figure 5 The status is filled in the printer 10.

[0061] The outer frame 14 of the printer 10 has a round, flat rectangular box shape, configured to be held in one hand and carried. Furthermore, the outer frame 14 of the printer 10 is configured to be placed vertically (standing upright on a flat surface) and horizontally (laying across a flat surface). Figure 1 and Figure 2 This shows the case where the printer 10 is placed vertically.

[0062] On the front side of the printer 10, a push-button power button 16 is located approximately in the center. The printer 10 is turned on and off by pressing and holding the power button 16 (a continuous press for a certain period of time). The power button 16 also functions as a light source, emitting light through a light source located inside it. This will be described later.

[0063] An outlet 18 is provided at the upper part (the upper part when the printer is placed vertically). The printed instant film 12 is discharged from this outlet 18.

[0064] A film packaging box loading chamber for opening and closing is provided on the back side of printer 10 (see reference). Figure 4 The film packaging box cover 20 is provided. A locking release lever 22 is also provided to release the lock on the film packaging box cover 20. Using the locking release lever 22 to release the lock, if the film packaging box cover 20 is opened, the film packaging box filling chamber is opened. If the film packaging box cover 20 is closed after the film packaging box has been filled, the film packaging box cover 20 is locked by a locking mechanism (not shown), and the film packaging box is sealed in a light-blocking state.

[0065] A USB cable connector cover 24 is provided on one side of the printer 10, which allows the connection of a USB (Universal Serial Bus) cable (not shown) to be opened and closed. The printer 10 charges its built-in battery via the USB cable connector exposed by opening the USB cable connector cover 24.

[0066] [Structure of the printer's printing section]

[0067] Figure 4 This is a cross-sectional view showing the general structure of the printer's printing section. Additionally, Figure 4 This shows the printer's horizontal placement.

[0068] like Figure 4 As shown, the printer 10, as a printing unit, includes a film packaging box filling chamber 30, a film feeding mechanism 32 for feeding out the instant film 12 from the film packaging box filled in the film packaging box filling chamber 30, a film transport mechanism 34 for transporting the instant film 12 fed out from the film packaging box, and a print head 36 for recording images on the instant film 12.

[0069] The film packaging box filling chamber 30 is formed as a recess into which the film packaging box 40 is embedded, and is opened and closed by the film packaging box cover 20.

[0070] Figure 5 It's a 3D model of the film packaging box. And, Figure 6 This is the front view of the film. Figure 7 This is the rear view of the developing film. Additionally, in Figures 5 to 7 In the diagram, the direction indicated by arrow F is the feeding direction of the developing film 12. That is, the developing film 12 is fed out along the direction indicated by arrow F and discharged from the housing 42.

[0071] The developing film 12 has a rectangular card shape. In the developing film 12, one side is configured as the exposure surface (the surface through which the image is recorded by exposure) 12a, and the other side is configured as the observation surface (the surface through which the recorded image is observed) 12b.

[0072] like Figure 7As shown, the exposure surface 12a of the developing film 12 has an exposure area 12c, a capsule 12d, and a collection section 12f. The exposure area 12c is the area where an image is recorded through exposure. The exposure area 12c becomes the printable area of ​​the developing film 12. The capsule 12d and the collection section 12f are positioned in front of and behind the exposure area 12c in the feed direction F. The capsule 12d is positioned in front of the exposure area 12c in the feed direction F. A developing solution capsule 12e containing developing solution is built into the capsule 12d. The collection section 12f is positioned behind the exposure area 12c in the feed direction F. An absorbent material 12g is built into the collection section 12f.

[0073] like Figure 6 As shown, an observation area 12h is provided on the observation surface 12b of the developing film 12. The observation area 12h is the area where the image is displayed. The image is displayed in the observation area 12h by developing the exposure area 12c. The observation area 12h is configured corresponding to the exposure area 12c. A frame 12i is provided around the observation area 12h. Therefore, the image is displayed within the frame. Furthermore, the observation area 12h is set to be slightly narrower than the exposure area 12c (set to be one size smaller). Therefore, when an image is recorded over the entire area of ​​the exposure area 12c, the image around the cropped area is printed.

[0074] Furthermore, the film 12 is viewed with the collecting section 12f facing upwards and the pouch section 12d facing downwards. Therefore, the image is printed with the collecting section 12f facing upwards and the pouch section 12d facing downwards.

[0075] After exposure, the instant film 12 is developed by spreading the developing solution in the capsule 12d onto the exposure area 12c. The developing solution in the capsule 12d is squeezed out from the capsule 12d and spread onto the exposure area 12c by passing the instant film 12 between the spreading rollers 34B. Any remaining developing solution during the spreading process is captured by the collection unit 12f.

[0076] The housing 42 has a rectangular box shape. The housing 42 has a rectangular exposure opening 42a on its front side. Furthermore, the housing 42 has a slit-shaped film discharge outlet 42b on its top surface. The developing film 12 is overlapped and housed within the housing, with its exposure surface 12a facing the front side of the housing 42 (exposure opening 42a side) and its bladder portion 12d facing the top surface of the housing 42 (film discharge outlet 42b side). The housing 42 also has a slit-shaped claw opening 42c on its bottom surface. The developing film 12 housed in the housing 42 is fed one sheet at a time towards the film discharge outlet 42b by allowing the claw 32a to enter through the claw opening 42c, and is discharged from the film discharge outlet 42b.

[0077] Multiple sheets (e.g., 10 sheets), namely film 12, are stacked in a film packaging box 40.

[0078] The film delivery mechanism 32 delivers one instant film 12 at a time from the film packaging cassette 40, which is filled in the film packaging cassette filling chamber 30. The film delivery mechanism 32 is equipped with a chuck 32a that moves back and forth along the feed direction of the instant film 12. The film delivery mechanism 32 uses the chuck 32a to remove one instant film 12 from the housing at a time and delivers the instant film 12 from the film packaging cassette 40.

[0079] The film transport mechanism 34 transports the instant film 12, which is fed out from the film packaging cassette 40 via the film delivery mechanism 32, at a certain speed. The film transport mechanism 34 includes a transport roller pair 34A and a spreader roller pair 34B. The transport roller pair 34A is driven by a motor (not shown) to rotate and clamps both sides of the instant film 12 for transport. The spreader roller pair 34B is driven by a motor (not shown) to rotate and clamps the entire instant film 12 for transport. During transport via the spreader roller pair 34B, the capsule 12d is flattened, and the instant film 12 is developed.

[0080] The print head 36 records an image on the instant film 12 fed from the film packaging cassette 40. The print head 36 is composed of a linear exposure head. The print head 36 illuminates the exposure surface 12a of the instant film 12, which is fed by the film transport mechanism 34, line by line with printing light, and records the image on the instant film 12 in a single scan.

[0081] [Electrical Structure of a Printer]

[0082] Figure 8 This is a block diagram representing the electrical components of a printer.

[0083] like Figure 8 As shown, the printer 10 includes: an operation detection unit 50 for detecting the operation of the power button 16, a light source unit 52 for illuminating the power button 16, a light source control unit 54 for controlling the illumination of the light source unit 52, a wireless communication unit 56 for wirelessly communicating with external devices via an antenna 56A, a power supply unit 58, a power control unit 60 for controlling the power supply from the power supply unit 58 and charging the power supply unit 58, a printer internal memory 62, a memory control unit 64 for reading data from or writing data to the printer internal memory 62, an operation detection unit 66 for detecting the operation of the printer 10, a film feed mechanism drive unit 68 for driving the film feed mechanism 32, a film transport mechanism drive unit 70 for driving the film transport mechanism 34, a print head drive unit 72 for driving the print head 36, and a printer microcomputer 80, etc.

[0084] The operation detection unit 50 detects the operation of the power button 16. The power button 16 is a button used to turn the printer 10 on and off by pressing and holding it. During the power-on period, the power button 16 is assigned the function of inputting a reprint command. Reprinting is the function of reprinting the last printed image. During the power-on period of the printer 10, the operation detection unit 50 detects a short press of the power button 16 (an operation of pressing and immediately removing it) and outputs its detection signal to the printer microcomputer 80.

[0085] The light source unit 52 is configured to switch the emitted light color. In the printer 10 of this embodiment, the light source unit 52 is composed of a tri-color LED (also called a full-color LED) having elements of three colors: R (red), G (green), and B (blue). The tri-color LED switches its emitted light color by selecting the mixing ratio of the three colors R, G, and B. This main light source is known, so a detailed description of it is omitted.

[0086] The light source 52 is located inside the power button 16 (see reference). Figure 4 The power button 16 is made entirely or partially transparent (or semi-transparent). If the light source 52 is made to emit light, light is emitted through its transparent (or semi-transparent) portion.

[0087] The light source control unit 54, according to the command from the printer microcomputer 80, causes the light source unit 52 to emit light in a specified light emission color and light emission mode.

[0088] The wireless communication unit 56, under the control of the printer-based microcomputer 80, communicates wirelessly with external devices via antenna 56A. As described above, the communication with external devices is performed according to short-range wireless communication standards.

[0089] The power supply unit 58 includes a battery and a power circuit, and supplies power to various parts of the printer 10. The battery is a rechargeable secondary battery that is charged by receiving power from an external source.

[0090] Under the control of the printer microcomputer 80, the power control unit 60 controls the power supply from the power supply unit 58 to each part and the charging of the battery of the power supply unit 58.

[0091] The printer's built-in memory 62 constitutes the storage unit of the printer 10, and stores printed image data and printer 10 setting data, etc. The printer's built-in memory 62 is composed of non-volatile memory such as EEPROM (Electrically Erasable Programmable Read-only Memory).

[0092] The memory control unit 64 reads data from the printer's built-in memory 62 and writes data to the printer's built-in memory 62 according to instructions from the printer microcomputer 80.

[0093] The motion detection unit 66 detects the movement of the printer 10. The motion detection unit 66 is, for example, composed of a motion sensor. Motion sensors are well-known, so a detailed description is omitted. Typically, a motion sensor is constructed by combining an accelerometer and a gyroscope, etc. The motion detection unit 66 detects the posture (vertical, horizontal, tilted, etc.) and movement (lifting, lowering, flipping, etc.) of the printer 10.

[0094] The film feed mechanism drive unit 68 includes a motor and its drive circuit for driving the chuck 32a of the film feed mechanism 32, and drives the film feed mechanism 32 according to instructions from the printer microcomputer 80.

[0095] The film transport mechanism drive unit 70 includes a motor and its drive circuit for driving the transport roller pair 34A of the film transport mechanism 34 and a motor and its drive circuit for driving the unfolding roller pair 34B, and drives the film transport mechanism 34 according to instructions from the printer microcomputer 80.

[0096] The printhead drive unit 72 includes a drive circuit for the printhead 36 and drives the printhead 36 according to instructions from the printer microcomputer 80.

[0097] The printer microcomputer 80 is a control unit that oversees the operation of the printer 10. The printer microcomputer 80 is a microcomputer equipped with a CPU (Central Processing Unit), ROM (Read Only Memory), and RAM (Random Access Memory), and performs various functions by executing a prescribed control program.

[0098] Figure 9 This is a block diagram of the main functions implemented by the printer's microcomputer.

[0099] The printer microcomputer 80 mainly functions as an image acquisition unit 80A, a print data generation unit 80B, a print control unit 80C, a representative color detection unit 80D, and a light emission control unit 80E.

[0100] The image acquisition unit 80A communicates wirelessly with the external device 100 via the wireless communication unit 56 and acquires image data of the image to be printed from the external device 100. When reprinting, it reads and acquires the image data of the last printed image from the printer's built-in memory 62.

[0101] The print data generation unit 80B converts the image data acquired by the image acquisition unit 80A into a data format that can be printed by the printing unit (a data format that can be printed on the instant film 12 by the print head 36), thereby generating print data (print data).

[0102] The print control unit 80C controls the feeding of the instant film 12 via the film feed mechanism 32 via the film feed mechanism drive unit 68. Furthermore, the film transport mechanism drive unit 70 controls the transport of the instant film 12 via the film transport mechanism 34. Additionally, the print head drive unit 72 controls the drive of the print head 36. The print head 36 is driven synchronously with the transport of the instant film 12 based on the print data generated by the print data generation unit 80B.

[0103] The representative color detection unit 80D divides the image to be printed into multiple regions along the vertical direction of the image, analyzes the image of each region, and detects its representative color. The representative color refers to the color used in the center of that region. For example, the representative color detection unit 80D calculates the color distribution of the image in each region and detects the color occupying the widest area as the representative color of that region. At this time, the representative color detection unit 80D detects the representative color of each region within the color gamut that can be reproduced by the light source unit 52.

[0104] Figure 10 This is a diagram illustrating an example of image segmentation.

[0105] like Figure 10 As shown, in the printer 10 of this embodiment, the image IM is divided into three equal parts along the vertical direction (upper region A1, middle region A2, and lower region A3), and the representative color of each region A1, A2, and A3 is detected. Furthermore, the vertical direction of the image here refers to the vertical direction when viewing the image (vertical direction).

[0106] exist Figure 10 In the example of the image IM shown, the representative color of the upper region A1 is light blue, the representative color of the middle region A2 is green, and the representative color of the lower region is yellow-green.

[0107] The light emission control unit 80E controls the light emission of the light source unit 52 via the light source control unit 54, and causes the power button 16, which is the light emission unit, to emit light in a predetermined color and pattern. The light emission control unit 80E causes the power button 16 to emit light at predetermined times. Specifically, the power button 16 emits light when receiving an image to be printed from the external device 100 and when printing the image.

[0108] When an image to be printed is received from an external device 100, a number of predetermined colors are switched sequentially at certain time intervals and made to emit light. For example, the seven colors red, orange, yellow, green, light blue, blue and purple (so-called rainbow colors) are switched sequentially at certain time intervals and made to emit light.

[0109] On the other hand, when printing an image, the representative colors of each region A1, A2, and A3 detected by the representative color detection unit 80D are switched sequentially according to the printing progress, and the colors are made to emit light. In this embodiment, the colors are switched sequentially and made to emit light in a time interval (T / 3s) that divides the time from the start of printing to the end of printing (T[s]) into three equal parts. The colors emit light in the order of the representative color of the upper region A1, the representative color of the middle region A2, and the representative color of the lower region A3. Therefore, in Figure 10 In the case of the image IM shown, the light emits light in the order of light blue, green, and yellow-green. Additionally, when the representative colors are achromatic colors such as black and gray, no light is emitted. That is, the light-emitting part is set to a state where it does not emit light (light off) at the corresponding time in the corresponding area.

[0110] Furthermore, in the printer 10 of this embodiment, the time from the start of printing to the end of printing refers to the time from the start of feeding the display film 12 to the end of discharge. Discharge is completed by the transport roller pair 34A through the rear end of the display film 12. In this state, the display film 12 is maintained in a state where a certain amount has been fed out from the discharge port 18 (it remains stationary at the rear end while being held in a state where it is held in a state of unfolding roller pair 34B). The time from the start of printing to the end of printing is constant and a known value, regardless of the image.

[0111] [External Devices]

[0112] As described above, the external device 100 consists of a computer with communication capabilities, especially a smartphone, tablet computer, laptop computer, PDA, mobile phone, and other mobile computers.

[0113] Figure 11 This is a block diagram illustrating an example of the hardware structure of an external device. Additionally, Figure 11 An example is shown where the external device 100 is a smartphone.

[0114] like Figure 11As shown, the external device (smartphone) 100 includes: a CPU 101 for controlling overall operation, a ROM 102 for storing basic input / output programs, a RAM 103 for serving as the working area of ​​the CPU 101, a built-in memory 104, a display 105, a touchpad 106 for detecting touch operations (position input) on the display screen, and an IMES (Indoor Messaging System) for using GPS (Global Positioning Systems) satellites or as an indoor GPS. The system (indoor messaging system) includes a GPS receiver 107 that receives GPS signals containing location information (latitude, longitude, and altitude) from an external device 100; a camera unit 108 that includes a photographic lens and an image sensor and electronically captures images; a microphone unit 109 that includes a microphone and inputs sound; a speaker unit 110 that includes a speaker and outputs sound; a communication unit 111 that communicates wirelessly with the nearest base station using an antenna 111A; a short-range wireless communication unit 112 that communicates with other devices (e.g., a printer 10) using an antenna 112A; a sensor unit 113 that includes various sensors such as a geomagnetic sensor, a gyroscope compass, and an accelerometer; and a media drive 114 that reads and writes data to a memory card 115. The built-in memory 104 is composed of non-volatile memory such as an EEPROM. In addition to various programs of the operating system executed by the CPU 101, the built-in memory 104 also stores image data of images captured by the camera unit 108 and image data acquired from other devices, as well as various other data.

[0115] The external device 100, in relation to the printer 10, has the following functions: enabling the printer 10 to print images captured by the camera unit 108; and enabling the printer 10 to print images recorded in the built-in memory 104. Furthermore, regarding these functions, it also has the function of editing the image to be printed.

[0116] Figure 12 This is a block diagram illustrating the main functions of an external device in relation to a printer.

[0117] like Figure 12 As shown, the external device 100 has the functions of a printing image acquisition unit 100A for acquiring an image to be printed, a printing image processing unit 100B for processing and editing the image to be printed, and a printing image sending unit 100C for sending the image to be printed to the printer 10.

[0118] The image acquisition unit 100A for printing acquires images for printing either by taking a picture or by retrieving them from the built-in memory 104. When acquiring an image for printing by taking a picture, the camera unit 108 is controlled based on operation input from the user (operation input to the touchpad 106, which serves as the operation unit), and the image to be printed is acquired by taking a picture. When acquiring an image for printing from the built-in memory 104, the image is acquired by reading the image stored in the built-in memory 104. For example, the user selects a folder containing the image storage location, the image stored in that folder is reproduced on the display, and the image to be printed is selected. The image acquired by the image acquisition unit 100A for printing is displayed on the display 105.

[0119] The image processing unit 100B for printing processes and edits the image to be printed (the image displayed on the display 105 as the image to be printed) based on the user's operation input (operation input to the touchpad 106, which serves as the operation unit). For example, it performs image processing such as image trimming, enlarging, rotating, template compositing, and image correction (noise removal, sharpness, hue, brightness, etc.).

[0120] The image transmitting unit 100C for printing sends the image to be printed to the printer 10 based on operation input from the user (operation input to the touchpad 106, which serves as the operation unit). The image is transmitted to the printer 10 via the near-field wireless communication unit 112.

[0121] The print command is sent, for example, by sliding the screen of the display 105 showing the image to be printed along a specified direction (e.g., from the bottom of the screen to the top). Alternatively, it is sent by touching the print button displayed on the screen.

[0122] [Printing process of the printing system based on this embodiment]

[0123] In the printing system of this embodiment, an image to be printed is captured or selected by an external device 100, and the captured or selected image is wirelessly sent to the printer 10 for printing.

[0124] Figure 13 It is a flowchart showing the processing sequence in external devices.

[0125] First, the printer 10 is detected (step S11). That is, the presence or absence of a printer 10 that can be connected via short-range wireless communication is detected. Then, it is determined whether the printer 10 is detected (step S12). If the printer 10 is not detected, an error message is displayed (step S13). For example, an error message such as "No printer can be connected" is displayed. On the other hand, when a printer 10 that can be connected is detected, connection establishment processing is performed.

[0126] If a connection is established, the printing mode is determined (step S14). That is, it is determined whether to print in either the mode of printing by taking a picture (picture printing) or the mode of printing by selecting an image recorded in the built-in memory 104 (reproducible printing). The mode is selected on the menu screen.

[0127] When the image capture / print mode is selected, the image to be printed is captured (step S15). Conversely, when the image reproduction / print mode is selected, the image to be printed is selected (step S16). Thus, the image to be printed is acquired. The acquired image is displayed on the display 105 as the image to be printed.

[0128] Next, it is determined whether image editing is being performed based on the user's operation input (operation input to the touchpad 106, which serves as the operation unit) (step S17). Whether image editing is being performed is determined based on whether an image editing operation has been performed. When an image editing operation is performed, image editing processing is performed based on the operation input (step S18).

[0129] Next, a print command is determined based on the user's input (step S19). If no print command is given, a cancel print command is determined (step S20). If a cancel print command is given, the process ends. Conversely, if a print command is given, the image is transmitted to printer 10 (step S21).

[0130] Figure 14 This is a flowchart illustrating the processing sequence in the printer. Additionally, it is assumed that a connection to external device 100 has already been established.

[0131] First, it is determined whether a print command has been issued (step S31). If a print command has been issued, it is determined whether image reception has started (step S32). If image reception has started, the power button 16 illuminates in a predetermined pattern (step S33). In the printer 10 of this embodiment, seven colors (so-called rainbow colors) – red, orange, yellow, green, light blue, blue, and purple – are illuminated simultaneously, switching sequentially at certain time intervals. Then, it is determined whether image reception is complete (step S34). If image reception is complete, the illumination stops (step S35).

[0132] Next, print data is generated from the received image data (step S36). Furthermore, the received image data is analyzed, and the representative colors of each region in the upper, middle, and lower sections are detected (step S37). That is, the image is divided into three equal parts along the vertical direction: the upper section, the middle section, and the lower section, and the representative colors of each segmented region are detected.

[0133] Next, the illumination mode of the power button 16 during printing is set according to the representative color of each detected area (step S38). In the printer 10 of this embodiment, the illumination mode is set by sequentially switching and illuminating the representative colors of the upper section, the middle section, and the lower section at time intervals that divide the time T (known) from the start of printing to the end of printing into three equal parts.

[0134] Next, printing is performed (step S39). As printing begins, the power button 16 illuminates (step S40). The power button 16 illuminates in a set illumination mode. That is, it illuminates in the order of the representative color of the upper, middle, and lower sections of the image to be printed when it is divided into three equal parts. Furthermore, it switches the illumination color and illuminates the image at intervals that divide the time T from the start to the end of printing into three equal parts. The user can visually identify the characteristics and atmosphere of the printed image by recognizing the illumination of the power button 16. Furthermore, the user can visually recognize the printing progress by recognizing the switching of the illumination colors.

[0135] As explained above, in the printer 10 according to this embodiment, the power button 16 is configured as a light-emitting unit, emitting light in a predetermined manner during the reception and printing of the image to be printed. Therefore, the operating state of the printer 10 can be determined from the illumination state of the power button 16. Furthermore, during printing, the representative colors of each region, determined by dividing the image into three equal parts, are emitted sequentially, thus allowing the characteristics and atmosphere of the printed image to be identified from the illumination state of the power button 16. This is particularly effective in instant film 12 where the image cannot be immediately confirmed even after printing is complete. Moreover, during printing, the representative colors of each region switch sequentially according to the printing progress, thus allowing the printing progress to be identified from the illumination state of the power button 16. Furthermore, by illuminating the power button 16 during printing, the user can focus on the printer 10. In addition, the user can enjoy the printing process. Furthermore, when detecting representative colors, the detection process can be simplified by detecting the representative colors of predetermined regions (in this embodiment, regions where the image is divided into three equal parts vertically).

[0136] [Variation Example]

[0137] [A variation of the representative color detection method]

[0138] In the above embodiment, the image to be printed is divided into three equal parts (upper, middle, and lower sections) along the vertical direction, and the structure of the representative color in each region is detected. However, the method of detecting the representative color is not limited to this. It is also possible to divide the image into more detailed sections to detect the structure of the representative color in each region.

[0139] Furthermore, the ratio (area ratio) of the divisions of each region does not necessarily need to be equal. That is, equal division is not required. It is sufficient to divide according to a predetermined composition ratio. For example, when dividing an image into three parts along the vertical direction, the division can be performed with the ratio (area ratio) of the upper, middle, and lower regions being 1:2:1. In this case, it is preferable to switch the light emission according to the ratio (area ratio) of the division of each region. That is, for example, when dividing an image into three parts along the vertical direction, if the ratio (area ratio) of the upper, middle, and lower regions is 1:2:1, the division can be performed with the time from the start of printing to the end of printing being 1:2:1, so that the representative color of each region switches and emits light sequentially.

[0140] Furthermore, the segmentation method is not limited to the vertical direction; it can be performed in a matrix structure. In this case, for example, the upper left region of the image can be used as the starting point and the lower right region as the ending point, causing the representative colors detected in each region to emit light sequentially. For example, when dividing the image into four parts in a matrix structure, the representative colors of each region are emitted in the order of the upper left region, upper right region, lower left region, and lower right region. That is, the emission order is set by scanning from the upper left to the lower right of the image.

[0141] Alternatively, the image can be divided into multiple regions in concentric circles, with the center as the center. However, when the image is divided vertically, the emission color is switched sequentially along the vertical direction, making it easier to grasp the characteristics and atmosphere of the image compared to other segmentation methods.

[0142] Furthermore, image segmentation does not necessarily require designating all regions of the image as objects. It is also possible to segment only a portion of the image as objects, as long as the regions representing the detection colors are predetermined.

[0143] Furthermore, for example, it can be configured such that when the image to be printed is a composite image, a representative color is detected for each region of the composite image, and the light is emitted sequentially. In addition, the composite image here includes an image that is composited by dividing the screen into multiple regions and applying an image to each of the divisions (segmented image (including collage image)).

[0144] Figure 15 This is a diagram representing an example of a composite image.

[0145] Figure 15 This example illustrates a scenario where the screen is divided into four equal parts in a matrix-like structure. In this case, the segmented image CI consists of four images. Specifically, it consists of the first image CI1 at the top left of the screen, the second image CI2 at the top right of the screen, the third image CI3 at the bottom left of the screen, and the fourth image CI4 at the bottom right of the screen.

[0146] Representative colors are detected for each region of each image. Specifically, detection is performed in regions CI1 of image 1, CI2 of image 2, CI3 of image 3, and CI4 of image 4. Therefore, the colors primarily used in each image are identified as representative colors for each region. That is, the colors primarily used in image CI1, image CI2, image CI3, and image CI4 are identified as representative colors for each region.

[0147] Furthermore, the emission mode is set to emit light in the order of the representative color of the area of ​​the first image CI1, the representative color of the area of ​​the second image CI2, the representative color of the area of ​​the third image CI3, and the representative color of the area of ​​the fourth image CI4 (the emission order is set by scanning from the upper left area of ​​the screen to the lower right area).

[0148] [A variation of the representative color detection method]

[0149] In the above embodiment, the method for detecting the representative color of each region is as follows: the color distribution of the image in each region is calculated, and the color occupying the widest area is detected as the representative color of that region. However, the method for detecting the representative color is not limited to this. Other known methods can be used.

[0150] [Examples of variations in light emission methods]

[0151] In the above embodiment, during printing, a structure is configured to sequentially switch and emit light on representative colors detected from each region of the image; however, the method of emitting light on each representative color can also be based on a flickering method. By employing a flickering-based emission method, the printing progress can be monitored in more detail. That is, the time until printing is completed can be determined by counting the number of flickers.

[0152] Furthermore, the emission color can be switched in a tiered manner. This allows for identification of area switching even when two consecutive areas detect the same representative color. Moreover, this tiered color switching keeps the user more focused on the printer 10, enhancing the printing experience.

[0153] [A variation of the light emission pattern when the representative color is achromatic]

[0154] In the above embodiments, when the representative color of the area is an achromatic color such as black or gray, the light-emitting part (power button 16) is not illuminated when the area is illuminated. However, the illumination method is not limited to this when the representative color is an achromatic color. Furthermore, it is possible to illuminate in a predetermined color. Also, it is possible to illuminate in a predetermined color and a predetermined illumination pattern. For example, it is possible to illuminate by flashing white or by changing to rainbow colors. Furthermore, when a light-emitting part is used that can illuminate only the outline portion (the outer edge portion), it is also possible to illuminate only the outline portion with a predetermined color and / or illumination pattern.

[0155] [Example of a variation in the light emission method when receiving an image to be printed]

[0156] When receiving an image to be printed, it can emit light in the representative color of the image, just as it would when printing. In this case, the external device 100 has the function of detecting the representative color.

[0157] Figure 16 This is a functional block diagram of an external device that has the function of detecting representative colors.

[0158] like Figure 16 As shown, the external device 100 further includes a printing image representative color detection unit 100D that detects the representative color of each area from the image printed by the printer 10, and a light emission mode information transmission unit 100E that sets the light emission mode based on the representative color of each area detected by the printing image representative color detection unit 100D and sends it to the printer 10.

[0159] The image representative color detection unit 100D divides the image printed by the printer 10 into multiple regions along the vertical direction of the image, and detects the representative color of each region. In this example, the image is divided into three equal parts along the vertical direction, and the representative color of each region is detected.

[0160] Information about the representative colors of each region detected by the image representative color detection unit 100D for printing is added to the luminous mode information transmission unit 100E.

[0161] The illumination mode information transmitting unit 100E sets the illumination mode of the illumination unit (power button 16) of the printer 10 when receiving an image based on the representative color information of each region detected by the print image representative color detection unit 100D. In this example, the illumination mode is set to illuminate sequentially in the order of the representative color of the upper region, the representative color of the middle region, and the representative color of the lower region. Then, the set illumination mode information is sent to the printer 10. At this time, the illumination mode information transmitting unit 100E sends the illumination mode information to the printer 10 before the print image transmitting unit 100C sends the print image.

[0162] When the printer 10 receives an image to be printed from the external device 100, it illuminates the light-emitting part (power button 16) according to the light-emitting mode information received in advance.

[0163] Figure 17 This is a block diagram illustrating the functions of a printer when it illuminates the light-emitting section based on information about the light-emitting pattern received from an external device.

[0164] like Figure 17 As shown, the printer 10 further includes a light emission mode information acquisition unit 80F that acquires light emission mode information from an external device 100. The light emission mode information acquisition unit 80F acquires light emission mode information transmitted from the external device 100 via a wireless communication unit 56. The function of the light emission mode information acquisition unit 80F is implemented by the printer microcomputer 80.

[0165] The light emission mode information acquired by the light emission mode information acquisition unit 80F is added to the light emission control unit 80E. When the light emission control unit 80E receives an image to be printed from the external device 100, it makes the light emission unit (power button 16) emit light according to the light emission mode information acquired by the light emission mode information acquisition unit 80F.

[0166] In this way, when receiving an image to be printed, the light-emitting part is also illuminated according to the image, thereby enabling the identification of the characteristics and atmosphere of the printed image from the illumination state of the light-emitting part. Furthermore, it allows the user to focus on the printer 10. In addition, it provides the user with the enjoyment of printing.

[0167] Furthermore, as shown in this example, when information about the representative color of the image to be printed (information about the light emission mode) can be obtained from the external device 100, there is no need to perform representative color detection processing in the printer 10. When printing, the light emission control unit 80E causes the light emission unit (power button 16) to emit light based on the light emission mode information obtained by the light emission mode information acquisition unit 80F.

[0168] Furthermore, the emission mode can be changed during reception and printing. For example, by changing the detection mode of the representative color during reception and printing, the emission mode can be changed at both times. For instance, during reception, the image to be printed is divided into five equal parts along the vertical direction, and the representative color of each area is detected to set the emission mode. On the other hand, during printing, the image to be printed is divided into three equal parts along the vertical direction, and the representative color of each area is detected to set the emission mode.

[0169] Furthermore, the time required for receiving is shorter than the time required for printing. Therefore, the emission mode during image reception can be set to repeatedly switch the emission color at certain time intervals during reception. On the other hand, if reception takes time, it is preferable to set the emission color to switch sequentially according to the progress of reception. Thus, the time until the end of reception can be measured from the emission state of the emission unit.

[0170] [A variation of the timing for emitting light from the light-emitting part]

[0171] In the above embodiments, the structure is designed to emit light from the light-emitting unit when receiving an image to be printed and during printing; however, the timing of emitting light is not limited to this. For example, when the power is turned on and off, it can emit light in a predetermined light-emitting mode (e.g., a rainbow-colored light-emitting mode). Furthermore, for example, when the remaining battery power is less than a threshold, it can emit light in a predetermined light-emitting mode (e.g., flashing red). Also, for example, when there are no remaining sheets of instant film 12, or when the remaining quantity is below a certain number of sheets, it can emit light in a predetermined light-emitting mode. Furthermore, it can emit light according to the operation of the external device 100. For example, in the external device 100, when capturing an image for printing, it can emit light in a predetermined light-emitting mode. Also, for example, in the external device 100, when editing an image for printing, it can emit light according to the content of the editing operation. And, when establishing communication with the external device 100, it can emit light in a predetermined light-emitting mode.

[0172] [Example of a modified light-emitting part]

[0173] In the above embodiment, the structure is designed to make the power button 16 light up, but the part that emits light is not limited to this.

[0174] Furthermore, the light-emitting components can be located in multiple positions. When the light-emitting components are located in multiple positions, each component can emit light sequentially. For example, when dividing an image into three parts to detect representative colors, the light-emitting components can be located in three positions and emitted sequentially.

[0175] Furthermore, in the above embodiment, a tri-color LED is used as the light source for the light-emitting part, but the type of light source is not limited to this. Any light source capable of switching the emitted color is acceptable. Additionally, for example, EL light sources (electroluminescent sources) such as OLEDs (Organic Light Emitting Diodes) capable of emitting color can also be used. Moreover, from the viewpoint of power consumption, semiconductor light sources are preferred.

[0176] Furthermore, the light source is not limited to point light sources; surface light sources can also be used. In this case, light sources that can change color within the surface can also be used.

[0177] [Examples of variations in communication methods]

[0178] In the above embodiments, the printer can communicate with the external device wirelessly, or it can communicate via a wired connection. Furthermore, when communicating wirelessly, the communication method is not particularly limited and can employ any known communication method.

[0179] [Example of a printer variation]

[0180] In the above embodiments, the application of the present invention to an instant printer was described as an example, but the application of the present invention is not limited thereto. Furthermore, it can be applied to various types of printers, such as thermal printers that print on thermal paper, thermal transfer printers that use ink ribbons, and inkjet printers that print by inkjet.

[0181] Furthermore, while the above embodiments have been described using the application of the invention to mobile printers as an example, the application of the invention is not limited thereto. It can also be applied to so-called stationary printers. In addition, mobile printers are typically used near the user (approximately within hand reach), therefore, it is particularly effective when applied to mobile printers.

[0182] Furthermore, the hardware implementing the functions of the image acquisition unit 80A, print data generation unit 80B, print control unit 80C, representative color detection unit 80D, and light emission control unit 80E can be composed of various processors. These processors include: general-purpose processors that execute programs and function as various processing units, such as CPUs (Central Processing Units); processors such as FPGAs (Field Programmable Gate Arrays) whose circuit configuration can be changed after manufacturing, i.e., Programmable Logic Devices (PLDs); and processors such as ASICs (Application Specific Integrated Circuits) with circuits specifically designed for performing specific processes, i.e., dedicated circuits. One processing unit constituting the inspection support device can be composed of one of the aforementioned processors, or it can be composed of two or more processors of the same or different types. For example, one processing unit can be composed of multiple FPGAs or a combination of a CPU and an FPGA. Furthermore, multiple processing units can also be composed of a single processor. As examples of a single processor comprising multiple processing units, firstly, there are computers such as client machines and servers, where a single processor is composed of one or more CPUs and software, functioning as multiple processing units. Secondly, there are systems-on-a-chip (SoCs), where a processor implements the overall system functionality, including multiple processing units, using a single integrated circuit (IC) chip. Thus, various processing units are constructed as hardware structures using one or more of these different processors. Furthermore, the hardware structure of these various processors is more specifically a circuit composed of combined semiconductor elements and other circuitry.

[0183] [Examples of external devices]

[0184] There are no particular restrictions on the external devices; they can be digital cameras or desktop personal computers.
