Description

[Technical field]

[0001] The present invention relates to an electronic device, a projection device, and a program. [Background technology]

[0002] Conventionally, projectors (projection devices) that project an input screen (input image) of a still image or a video (image) onto a screen are known. When using a projector, various settings are made, such as color adjustment of the screen to be projected, screen shape adjustment, input destination setting, device operation setting, and network setting. These various settings are made by operating buttons on the projector body or a remote control or the like on a displayed menu screen, and the menu screen is displayed in one of the set languages ​​(English, French, German, Japanese, etc.).

[0003] Here, when a user attempts to make various settings by displaying a menu screen, if the screen is displayed in a language that the user cannot read, the user will be unable to understand the setting items, and even changing the language setting (to a language that the user can read) will be difficult.

[0004] Therefore, it is conceivable to place a "Language setting" item on the first (top) menu screen. However, language setting is rarely required, and if the "Language setting" item is placed on the first menu screen, which is used frequently, the menu screen will become cumbersome, and the burden on the user's normal operations will increase for cases that rarely occur.

[0005] Also, an image projection device is known that recognizes characters included in an input screen and sets the language to that of the recognized characters (see Patent Document 1). [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2014-29396 A Summary of the Invention [Problem to be solved by the invention]

[0007] However, in the image projection device described in Patent Document 1, since the input screen must contain characters, there is a risk that the language setting cannot be performed depending on the input screen. Furthermore, in the image projection device described in Patent Document 1, projection of the input screen is essential, which makes the processing complicated and places a heavy burden on the user.

[0008] An object of the present invention is to set the language easily and reliably. [Means for solving the problem]

[0009] In order to solve the above problem, an electronic device of the present invention includes a processor that executes a measurement process of measuring a non-operation time after starting to display a first screen expressed in a certain language, a determination process of determining whether or not the non-operation time has reached a preset language setting transition time, and a display control process of displaying a language setting screen when it is determined by the determination process that the non-operation time has reached the language setting transition time. In the measurement process, the processor measures a non-operation time after starting to display the language setting screen, and in the display control process, the processor determines whether or not the non-operation time of the language setting screen has reached a language setting end time set in advance, and ends the display of the language setting screen when the language setting end time has been reached. .

[0010] The projection device of the present invention includes a processor that executes a measurement process of measuring a non-operation time after starting projection of a first screen expressed in a certain language, a determination process of determining whether the non-operation time has reached a preset language setting transition time, and a projection control process of projecting a language setting screen when it is determined by the determination process that the non-operation time has reached the language setting transition time. In the measurement process, the processor measures a non-operation time after the start of displaying the language setting screen, and in the projection control process, the processor determines whether or not the non-operation time of the language setting screen has reached a language setting end time set in advance, and ends the projection of the language setting screen when the language setting end time has been reached. . Effect of the Invention

[0011] According to the present invention, the language can be set easily and reliably. [Brief description of the drawings]

[0013] Hereinafter, an embodiment and a modification of the present invention will be described in detail with reference to the accompanying drawings. Note that the present invention is not limited to the illustrated examples.

[0014] (Embodiment) An embodiment of the present invention will be described with reference to Figs. 1 to 9. First, the device configuration of this embodiment will be described with reference to Figs. 1 to 3. Fig. 1 is an external view of a projector 1 of this embodiment. Fig. 2 is a block diagram showing a circuit configuration of a main body 10. Fig. 3 is a block diagram showing a functional configuration of the main body 10.

[0015] As shown in FIG. 1, a projector 1 as an electronic device and a projection device is installed in an office or the like, and projects an input screen of input screen data (input image data) of a still image or a moving image onto a screen. The projector 1 includes a main body 10 and a power supply unit 20. The main body 10 is the main body of the projector 1 that projects the input screen. The main body 10 has a housing having a substantially rectangular parallelepiped shape, for example, but the corners of the housing may be rounded or rounded, or each surface may have irregularities. Alternatively, the housing of the main body 10 may have a shape different from a rectangular parallelepiped, for example, a shape having a curved surface such as an elliptical cylinder shape. A projection lens 141 is disposed on the housing of the main body 10 as an exit port for projection light.

[0016] A plurality of legs 101, for example, three legs (two legs are shown here), whose length can be changed and fixed, are provided on one of the faces (bottom face / lower face) of the housing of the main body 10. By adjusting the length of each leg, the emission direction of the projection light, that is, the projection direction of the image, can be determined. The bottom face of the main body 10 does not necessarily have to be used as the installation face, and the main body 10 may be rotated 90 degrees and placed vertically. In order to enable adjustment of the projection direction even when placed vertically, the legs may be provided on a face other than the bottom face, or an attachment part may be provided that allows the legs on the bottom face to be removed and attached to another face. An operation unit 12 including a (push) button and the like is provided on the face (upper face) opposite the bottom face of the housing of the main body 10.

[0017] The four faces (including the front face) perpendicular to the bottom face of the housing of the main body 10 are each provided with an appropriate air intake 102, and the front face is provided with an exhaust 103. An input terminal for a cable connected to an external device 30 (FIGS. 2 and 3) and a connection terminal for a power supply cable 22 connected to the main body 21 of the power supply unit 20 are located on the rear face opposite the front face of the housing of the main body 10. The external device 30 is a device that transmits input screen data for projection to the projector 1, and is, for example, a PC (Personal Computer). The power supply cable 22 can be removed from the connection terminal of the housing of the main body 10 when the main body 10 is not in operation.

[0018] The power supply unit 20 supplies power to the main body unit 10 and includes a main body unit 21 having a battery, an AC (Alternating Current) / DC (Direct Current) conversion unit, etc., a power supply cable 22, and a cable 23. The power supply unit 20 converts power input from the battery of the main body unit 21 or power input from an external power source (external AC power source, mainly commercial power source) C1 in the AC / DC conversion unit, and supplies the power at a predetermined DC voltage to the main body unit 10. The power supply unit 20 is connected between the external power source (for example, a power supply terminal (outlet) of an AC 100V commercial power source) C1 and the main body unit 21 of the power supply unit 20 by the cable 23. The cable 23 may be detachable from the main body unit 21.

[0019] Next, the internal circuit configuration of the main body 10 of the projector 1 will be described with reference to Fig. 2 and Fig. 3. As shown in Fig. 2, the main body 10 includes a CPU (Central Processing Unit) 11, an operation unit 12, a RAM (Random Access Memory) 13, a projection unit 14, a storage unit 15 as a storage means, a communication unit 16, an audio output unit 17, an RTC (Real Time Clock) 18, and a power supply unit 19. The units of the main body 10 except for the power supply unit 19 are connected to each other via a bus B1.

[0020] The CPU 11 is a hardware processor that controls the overall operation of the main body 10. The CPU 11 loads a specified program from among the programs stored in the storage unit 15 into the RAM 13, and executes various processes in cooperation with the loaded program.

[0021] In this embodiment, the CPU 11 executes a menu control process, which will be described later, according to a menu control program P1 stored in the storage unit 15. More specifically, as shown in FIG. 3, the CPU 11 functions as a menu control unit 111, a projection control unit 112, and an operation processing unit 113 according to the menu control program P1. The menu control unit 111 generates menu screen data of a menu screen for setting various items of the menu of the projector 1, synthesizes the menu screen data with input screen data of a still image or a moving image input from the external device 30, and projects the menu screen data on the screen SC by the projection unit 14, and generates language setting screen data of a language setting screen for setting the language of the menu screen when there is no operation for a predetermined time (language setting transition time 50, which will be described later), and projects the language setting screen data on the screen by the projection unit 14. The screen SC is a flat surface that displays an image (screen) projected from the projector 1.

[0022] The projection control unit 112 controls the projection unit 14 and causes the projection unit 14 to project input screen data input from the external device 30, menu screen data instructed by the menu control unit 111, and language setting screen data of the language setting screen onto the screen SC. The operation processing unit 113 outputs operation information corresponding to the operation content input by the user via the operation unit 12 to the menu control unit 111. The operations of the menu control unit 111, the projection control unit 112, and the operation processing unit 113 will be described in more detail later.

[0023] Returning to Fig. 2, the operation unit 12 has various buttons (keys), accepts key operations from the outside, such as a user, and outputs them to the CPU 11 as operation information. The various buttons include, for example, cursor keys that accept up, down, left, and right inputs, an ENTER key that accepts a confirmation input, an ESC key that accepts a cancellation input, and a MENU key that accepts inputs such as menu display and end. The operation unit 12 may also include a power key. The operation unit 12 may also be configured to have a remote controller and a receiving unit that accepts a signal (such as an infrared signal) from the remote controller.

[0024] The RAM 13 is a volatile semiconductor memory from which information can be read and written, provides a work area for the CPU 11, and temporarily stores data and programs.

[0025] The projection unit 14 generates light of each color of RGB according to an instruction from the CPU 11, and generates and emits projection light at a pixel position and timing according to the input screen data. The projection unit 14 has, for example, a light emitting unit as a light source, an optical system such as a projection lens 141, a driving unit such as a motor, and a fan for discharging (exhausting) heat. This optical system has some or all optical components such as lenses, prisms, mirrors, and filters, and at least some of the optical components may be movable in the optical axis direction to adjust the focal position. In addition, this optical system may include a movable mirror related to DLP (Digital Light Processing), for example, a digital (micro)mirror device (DMD: Digital Mirror Device) arranged two-dimensionally according to the number of display pixels.

[0026] The storage unit 15 is a storage unit such as a flash memory capable of reading and writing information, and stores various data and programs. In particular, the storage unit 15 stores a menu control program P1, a setting language 40, a language setting transition time 50, and a language setting end time 60, which will be described later.

[0027] The communication unit 16 performs wired communication with the external device 30 according to a predetermined communication standard. The CPU 11 can transmit and receive information to and from the external device 30 via the communication unit 16. Examples of the predetermined communication standard include analog RGB signals, USB (Universal Serial Bus), and HDMI (High Definition Multimedia Interface; registered trademark), and a plurality of these may be selectively usable.

[0028] The communication unit 16 may also be configured to include a wireless LAN communication unit that performs wireless communication with the external device 30 in accordance with a wireless LAN (Local Area Network) standard such as IEEE802.11.

[0029] The audio output unit 17 has an amplifier, a speaker, etc., and generates an electrical signal of audio, appropriately amplifies it, and outputs the audio in accordance with the audio data input from the CPU 11. In particular, the audio output unit 17 is capable of outputting audio in accordance with the audio data of the input screen data of the moving image input from the external device 30.

[0030] The RTC 18 is a clock unit that keeps track of the current date and time, and outputs the kept current date and time information to the CPU 11 .

[0031] The power supply unit 19 is a power supply unit such as a DC / DC converter that supplies DC power supplied via the power supply unit 20 to each component of the main body unit 10 .

[0032] Next, information stored in the storage unit 15 will be described with reference to Fig. 4. Fig. 4(a) is a diagram showing a set language 40. Fig. 4(b) is a diagram showing a language setting transition time 50. Fig. 4(c) is a diagram showing a language setting end time 60.

[0033] As shown in Fig. 4(a), the storage unit 15 stores a set language 40. The set language 40 is a language set for the menu screen, and here, for example, Japanese is set in advance, but the present invention is not limited to this. The set language 40 is also updateable.

[0034] As shown in FIG. 4(b), the storage unit 15 stores a language setting transition time 50. The language setting screen is a setting screen for the language of the menu screen. After the menu screen starts to be displayed, if the menu screen is displayed in a language that the user cannot understand, the user may not be able to operate it. For this reason, if there is no user operation for a predetermined period of time after the menu screen starts to be displayed, the display is automatically transitioned to the language setting screen. The language setting transition time 50 is a predetermined time set in advance until the display of the language setting screen is automatically transitioned to due to no user operation after the menu screen starts to be displayed, and is set to, for example, 10 seconds here, but is not limited to this.

[0035] As shown in FIG. 4(c), the storage unit 15 stores a language setting end time 60. If the user does not select a language for the menu screen for a predetermined time after the language setting screen starts to be displayed, it is determined that the user does not want to change the language of the menu screen, and the display of the menu screen is automatically shifted to. The language setting end time 60 is a predetermined time set in advance from the start of the display of the language setting screen until the language setting is ended and the display of the menu screen is automatically shifted to due to no user operation, and is set to 10 seconds, for example, but is not limited to this. The CPU 11 may be configured to be able to change the values ​​of the language setting transition time 50 and the language setting end time 60 stored in the storage unit 15 in response to an operation input from the user via the operation unit 12.

[0036] Next, the operation of the projector 1 (main body 10) will be described with reference to Figs. 5 to 9. Fig. 5 is a flowchart showing menu control processing. Fig. 6 is a diagram showing a Japanese menu screen 301. Fig. 7 is a diagram showing a language setting screen 302. Fig. 8 is a diagram showing an English menu screen 303. Fig. 9 is a diagram showing a Thai menu screen 304.

[0037] For example, it is assumed that the projector 1 is shared by a company or meeting that multinational users belong to or participate in, or that the projector 1 is lent to multinational users. For this reason, it is assumed that each user of the projector 1 can use different languages.

[0038] 3, the main body 10 is supplied with power from the power supply unit 20, and the power is turned on, and the CPU 11 functions as a projection control unit 112. Based on input screen data input from the external device 30 via the communication unit 16, the projection control unit 112 projects a screen of the input screen data (input screen) on the screen SC by the projection unit 14, and appropriately causes the audio output unit 17 to output audio data of the input screen data.

[0039] In parallel with the above projection, when the power is turned on in the main body 10, the CPU 11 executes menu control processing in accordance with the menu control program P1 stored in the storage unit 15. For this reason, the following description will be given assuming that the CPU 11 functions as a menu control unit 111, a projection control unit 112, and an operation processing unit 113.

[0040] 5, the menu control unit 111 determines whether or not operation information for starting menu display has been input from the user via the MENU key of the operation unit 12 from the operation processing unit 113 (step S11). If operation information for starting menu display has not been input (step S11; NO), the process proceeds to step S11.

[0041] When operation information for starting menu display is input (step S11; YES), the menu control unit 111 reads the set language 40 stored in the storage unit 15, creates menu screen data showing a menu screen in a language corresponding to the set language 40, outputs the created menu screen data to the projection control unit 112, and instructs the projection control unit 112 to synthesize the menu screen with the input screen data to be projected and project the menu screen onto the synthesized screen (step S12). In step S12, the projection control unit 112 creates synthesized screen data in response to the instruction from the menu control unit 111 so as to superimpose the menu screen of the menu screen data on the input screen data to be projected, and controls the projection unit 14 to project the synthesized screen data of the created synthesized screen data onto the screen SC.

[0042] In step S12, for example, when the set language 40 is Japanese, a composite screen of the Japanese menu screen 301 and the input screen shown in Fig. 6 is projected onto the screen SC. The menu screen 301 is a menu screen for performing menu operation settings such as image adjustment, volume adjustment, screen settings, input settings, device settings, multimedia settings, and network settings.

[0043] Then, the menu control unit 111 starts measuring (counting) the non-operation time during which there is no operation input from the user via the operation unit 12 from the start of projection of the menu screen in step S12 using the current date and time information clocked by the RTC 18 (step S13).Then, the menu control unit 111 determines whether or not there is an input of operation information of a menu operation corresponding to the menu screen being projected from the user to the operation unit 12 from the operation processing unit 113 (step S14).

[0044] If no operation information is input (step S14; NO), the menu control unit 111 reads the language setting transition time 50 stored in the storage unit 15, and determines whether or not the non-operation time being measured from step S13 has reached the language setting transition time 50 (step S15). If the language setting transition time 50 has not been reached (step S15; NO), the process proceeds to step S14.

[0045] When the language setting transition time 50 is reached (step S15; YES), the menu control unit 111 creates language setting screen data showing a language setting screen on which the language to be used can be selected, outputs the created language setting screen data to the projection control unit 112, and instructs the projection control unit 112 to combine the data with the input screen data to be projected and project the language setting screen into the combined screen (step S16). In step S16, the projection control unit 112 creates combined screen data in response to the instruction from the menu control unit 111 so as to superimpose the language setting screen of the language setting screen data on the input screen data to be projected, and controls the projection unit 14 to project the combined screen data of the created combined screen data onto the screen SC.

[0046] In step S16, for example, a composite screen of the language setting screen 302 and the input screen shown in Fig. 7 is projected onto the screen SC. The language setting screen in Fig. 7 accepts selection input of the language to be used from English, French, German, Thai, and Japanese, which are arranged in a predetermined order.

[0047] Then, the menu control unit 111 starts measuring a non-operation time during which there is no operation input from the user via the operation unit 12 from the start of projection of the language setting screen in step S16, using the current date and time information clocked by the RTC 18 (step S17).Then, the menu control unit 111 determines whether or not the operation processing unit 113 has input operation information for selecting a language corresponding to the language setting screen being projected from the user to the operation unit 12 (step S18).

[0048] If no operation information for language selection is input (step S18; NO), the menu control unit 111 reads the language setting end time 60 stored in the storage unit 15, and determines whether or not the non-operation time being measured from step S17 has reached the language setting end time 60 (step S19). If the language setting end time 60 has not been reached (step S19; NO), the process proceeds to step S18.

[0049] If operation information for language selection is input (step S18; YES), the menu control unit 111 selects and sets the language to be used in accordance with the operation information for language selection input after step S18 (for example, operation information for moving the cursor to the language to be selected using the cursor keys of the operation unit 12 and confirming the language selection using the ENTER key), and updates the set language 40 stored in the memory unit 15 to the selected language (step S20).

[0050] When the language setting end time 60 is reached (step S19; YES), or after execution of step S20, the menu control unit 111 creates menu screen data showing a menu screen in a language corresponding to the set language 40 (step S19; YES), or in the language set in step S20, and outputs the created menu screen data to the projection control unit 112, instructing it to combine the data with the input screen data to be projected, update the menu screen in the combined screen, and project it (step S21).

[0051] In step S21, for example, when English is selected and input as the language to be used, a composite screen of the English menu screen 303 and the input screen shown in Fig. 8 is projected onto the screen SC. Also, when Thai is selected and input as the language to be used, a composite screen of the Thai menu screen 304 and the input screen shown in Fig. 9 is projected onto the screen SC. The Japanese menu screen 301, the English menu screen 303, and the Thai menu screen 304 have the same menu contents, except that the languages ​​used are different.

[0052] When operation information is input (step S14; YES), or after step S21 is executed, the menu control unit 111 executes menu processing corresponding to the operation information in response to the input of operation information of the menu operation from the user via the operation unit 12 from the operation processing unit 113 in response to the menu screen being projected in step S12 or S21 (step S22). Then, the menu control unit 111 determines whether or not operation information of an operation to end the menu processing from the user via the MENU key of the operation unit 12 has been input from the operation processing unit 113 (step S23).

[0053] If the operation information for ending the menu processing has not been input (step S23; NO), the process proceeds to step S22. If the operation information for ending the menu processing has been input (step S23; YES), the menu control unit 111 cancels the instruction to the projection control unit 112 to combine the menu screen data in step S12 or S21 (step S24), and the process proceeds to step S11.

[0054] As described above, according to this embodiment, the projector 1 includes a CPU 11 (menu control unit 111) as a processor that executes a measurement process using the RTC 18 to measure a non-operation time after starting projection of a menu screen as a first screen expressed in a certain language, a determination process to determine whether or not the non-operation time has reached a preset language setting transition time 50, and a projection control process to cause the projection unit 14 to project the language setting screen 302 when it is determined by the determination process that the non-operation time has reached the language setting transition time 50.

[0055] Therefore, even if the menu screen is displayed in a language the user does not understand and the user is unable to operate it, the language setting screen 302 is automatically displayed, allowing the user to easily and reliably set the language using the language setting screen 302. In this way, it is possible to reduce cases where the user becomes confused when operating the menu for various settings.

[0056] Furthermore, when an operation for selecting a language for the menu screen is performed by the operation unit 12 in response to the projected language setting screen 302, the CPU 11 sets the language for the menu screen to the selected language. This makes it possible to set the language more easily and reliably.

[0057] Furthermore, after starting projection of the language setting screen 302, the CPU 11 measures the time during which no operation is performed on the operation unit 12, determines whether or not the time during which no operation is performed on the language setting screen 302 reaches a preset language setting end time 60, and projects the menu screen when the language setting end time 60 is reached. Therefore, when the user determines that there is no need to change the language of the menu screen and does not perform any operation, the menu screen can be easily reprojected.

[0058] Furthermore, the CPU 11 projects the menu screen and the language setting screen 302 in a composite manner onto a normal input screen serving as a normal second screen. This allows the menu screen, the language setting screen 302, and the input screen to be projected in parallel.

[0059] (Modification) A modification of the above embodiment will be described below. In the above embodiment, the language setting screen 302 for selecting and inputting the language to be used, which is projected in step S16 of the menu control process, lists selectable language candidates in a predetermined order, but the present invention is not limited to this.

[0060] In this modification, in step S16 of the menu control process, the menu control unit 111 creates language setting screen data for a language setting screen in which language candidates are arranged in order of priority. For example, language candidates are arranged from top to bottom in order of priority.

[0061] The priority is given to a language that has been selected more frequently in the past. For example, the menu control unit 111 stores the selection count number of each selectable language in the storage unit 15 as language history information so as to increment the selection count number of the language updated in step S20 by +1. In step S16, the menu control unit 111 creates language setting screen data for a language setting screen in which language candidates are arranged in order of priority, with the selection count number of each language stored in the storage unit 15 being the priority, starting from the highest selection count number. Note that the language history information may be the display time of the menu screen of each language instead of the selection count number of each language.

[0062] The priority order may be such that a higher priority is given to a language of a region that corresponds to the voltage and frequency of the AC power supply supplied to the projector 1. For example, the projector 1 is assumed to be exported to various countries around the world, or to be brought by a user traveling to each country and used in each country. Also, the power supply unit 20 has a detection unit (not shown) for the voltage and frequency of the AC power supply, and the storage unit 15 stores a language table in which a language is associated with the voltage and frequency of the AC power supply in the country in which the language is used.

[0063] For example, in step S16, the menu control unit 111 obtains the voltage and frequency of the AC power source detected by the detection unit of the power supply unit 20, reads the language table from the storage unit 15, and creates language setting screen data for a language setting screen in which language candidates corresponding to the detected AC power source voltage and frequency are arranged in order of priority, with the higher the priority of the language candidate. The target of detection and priority order may be the voltage or frequency of the AC power source.

[0064] Also, the menu control unit 111 may be configured to create language setting screen data for a language setting screen in which language candidates are arranged in order of priority such that the priority of the language of the menu screen being projected is lowered in step S12. For example, when a composite screen of a Japanese menu screen is projected in step S12, a language setting screen 302 is created in step S16 in which Japanese is given the lowest priority (placed at the bottom), as shown in FIG.

[0065] As described above, according to this modification, the CPU 11 (menu control unit 111) arranges in order of priority a plurality of languages ​​that are candidates for selection on the language setting screen 302. This allows the user to easily select an appropriate language with a high priority.

[0066] Furthermore, the CPU 11 stores history information of the selected languages ​​in the storage unit 15, and sets the priority order of the multiple languages ​​on the language setting screen 302 according to the history information of the stored languages. This allows the user to easily select an appropriate language that has been selected frequently.

[0067] Furthermore, the CPU 11 executes a detection process for detecting at least one of the voltage and frequency of the AC power supply supplied to the projector 1 (main body 10) by the detection unit. The CPU 11 sets a high priority to the language of the region corresponding to at least one of the detected voltage and frequency. This allows the user to easily select an appropriate language for the region corresponding to the supplied AC power supply.
