(First embodiment)
In the present embodiment, a tablet terminal will be described as an example of an electronic device. The electronic device is not limited to a tablet terminal. For example, in addition to various cameras such as a single-lens reflex camera, a mirrorless camera, and a compact digital camera, various electronic devices such as a smartphone, a notebook personal computer, and a portable game machine may be used.

  FIG. 1 is a diagram illustrating an example of an appearance of an electronic device 100 according to the first embodiment. The electronic device 100 includes a display unit 110 and a frame unit 120 on the front side. An imaging unit 130 is provided in a part of the frame unit 120. An imaging unit 135 is provided on the back surface part 140. The configuration illustrated in FIG. 1 is merely an example, and other configurations may be provided. Further, the number and arrangement of the imaging units are not limited to the example shown in FIG. There may be one imaging unit or three or more imaging units.

  The display unit 110 can be a variety of displays such as a liquid crystal display or an organic EL (Electro-Luminescence) display. The display unit 110 has a display area for displaying various images and information. The frame unit 120 is a member that protects the display unit 110 by surrounding the display unit 110. Generally, the frame portion 120 has a frame region of a light color such as white or a dark color such as black. In this embodiment, the frame part 120 shall have a black frame area | region. The frame portion 120 and the back surface portion 140 can be made of a resin material, a reinforcing fiber, a metal, or the like.

  FIG. 2 is a block diagram illustrating an example of a configuration of the electronic device 100 according to the present embodiment. The electronic device 100 includes a display unit 110, a frame unit 120, an imaging unit 210, a control unit 220, an emphasizing unit 230, a detection unit 240, an instruction receiving unit 260, a recording unit 270, and a recording control unit 271.

  The imaging unit 210 includes a lens 211, an imaging element 212, and a processing unit 213. The imaging unit 210 may be the imaging unit 130 illustrated in FIG. 1 or the imaging unit 135. The image sensor 212 converts the light obtained through the lens 211 into an electrical signal. The processing unit 213 sends data (referred to as image data) obtained by performing predetermined image processing on the electrical signal obtained by the image sensor 212 to the control unit 220.

  The control unit 220 includes a buffer 221 that temporarily stores the image data acquired by the imaging unit 210. The control unit 220 can include a CPU, a memory, and the like (not shown), and can control the electronic device 100 in accordance with a software program stored in the memory. The control unit 220 transmits the image data stored in the buffer 221 to the enhancement unit 230 (display control unit 231) and the recording control unit 271.

  The emphasizing unit 230 includes a display control unit 231. The emphasizing unit 230 performs a process of emphasizing the boundary region between the display unit 110 and the frame unit 120. The display control unit 231 controls the image displayed on the display unit 110. In the present embodiment, an example in which the boundary region between the display unit 110 and the frame unit 120 is emphasized by the display control unit 231 controlling the display of the display unit 110 will be described. Details will be described later.

  The detection unit 240 detects the illuminance around the electronic device. For example, the detection unit 240 can be an illuminance sensor. The detection result of the detection unit 240 is sent to the display control unit 231. The display control unit 231 can perform display control according to the detection result of the detection unit 240.

  The display unit 110 performs display according to the display control of the display control unit 231.

  The instruction receiving unit 260 receives an operation instruction for the electronic device 100. For example, the instruction receiving unit 260 receives an operation instruction input from the user. The instruction receiving unit 260 may receive an operation instruction input via an operation button (not shown), or may receive an operation instruction input via a touch panel integrated with the display unit 110. Or you may receive the operation instruction according to the audio | voice input from a user. The operation instruction includes an imaging instruction. The operation instructions may include various other instructions. The operation instruction received by the instruction receiving unit 260 is sent to the control unit 220.

  When the imaging instruction is sent, the control unit 220 transmits the imaging instruction to the recording control unit 271.

  The recording control unit 271 records image data in the recording unit 270 based on the imaging instruction sent from the control unit 220. With this processing, the image to be imaged displayed on the display unit 110 is recorded in the recording unit 270. In the present embodiment, the form in which the image data is recorded in the recording unit 270 is shown, but the present invention is not limited to this form. For example, the electronic device 100 may be configured to be connectable to a cloud server through a network or the like. The recording control unit 271 may be configured to transmit image data to the cloud server and record the image data on the cloud server when an imaging instruction is sent.

  The recording unit 270 can be a flash memory such as SRAM, DRAM, EEPROM, or USB memory.

  FIG. 3 is a diagram illustrating a specific example in which an image to be imaged is displayed on the display unit 110. As described above, an image obtained by the imaging unit 210 is displayed on the display unit 110 in accordance with control by the display control unit 231.

  In FIG. 3, it is assumed that the user is shooting a landscape in the dark. Then, the user determines an appropriate imaging range (framing) while confirming the imaging target image displayed on the display unit 110. When the user determines that the image displayed on the display unit 110 is within an appropriate imaging range, the user inputs an imaging instruction to the electronic device 100. In response to the imaging instruction, image data is recorded in the recording unit 270.

  3 is a landscape including a mountain that floats in the dark just before sunset. In the lower left area of the display unit 110, a dark lake is included. Since the frame part 120 of this embodiment has a black frame area, the boundary between the display part 110 and the frame part 120 is unclear. For this reason, the user cannot clearly confirm the outer edge of the imaging target. Therefore, there is a possibility that the image data recorded in the recording unit 270 by performing the imaging instruction is different from the image desired by the user.

  In the present embodiment, the frame 120 is described as a black frame region. However, when the frame 120 is not completely black, the display unit 110 is also a dark color. And the frame portion 120 become unclear. Also, here, the landscape is taken as an example, but the same problem occurs when trying to capture a person. That is, since the outer edge of the imaging target is unclear, for example, an image with broken hair may be captured.

  3 shows an example in which the frame 120 is a black region and the image to be captured includes a black subject portion. Conversely, the color of the frame region is white or the like. Even in the case of a light color system and a white subject (for example, a cloud) included in the imaging target, the boundary is still unclear.

  FIG. 4 is a diagram for explaining the outline of the enhancement process performed by the enhancement unit 230 in the present embodiment. The emphasizing unit 230 performs a process of emphasizing the boundary region 430 between the display unit 110 and the frame unit 120. In the present embodiment, the boundary region 430 is included in the display unit 110. Note that the size of the boundary region 430 is not limited to the illustrated example. It is sufficient that the user can clearly check the boundary.

  FIG. 5 is a diagram illustrating an example of a result of the enhancement processing performed by the enhancement unit 230 according to the present embodiment. The emphasizing unit 230 performs a process of emphasizing the boundary region 430 between the display unit 110 and the frame unit 120. Specifically, the display control unit 231 included in the emphasizing unit 230 performs a process of changing the luminance or color of some of the pixels constituting the image displayed on the display unit 110.

  Note that the display control unit 231 has a frame buffer for one frame corresponding to the display unit 110, for example, and stores each pixel of the image data sent from the buffer 221 of the control unit 220 in the frame buffer. The display control unit 231 can specify a pixel displayed at a predetermined position of the display unit 110 according to the position stored in the frame buffer. The display control unit 231 performs predetermined image processing on the pixels stored in the frame buffer as necessary. The display control unit 231 performs control so that each pixel stored in the frame buffer is displayed at a corresponding position on the display unit 110.

  In the present embodiment, the display control unit 231 changes the luminance or color of each pixel constituting the region (boundary region) adjacent to the frame unit 120 in the display region of the display unit 110. Then, the display control unit 231 displays the changed pixels in the boundary area of the display unit 110. In this way, hereinafter, changing the luminance or color of each pixel constituting the boundary region is simply expressed as changing the luminance or color of the boundary region.

  The display control unit 231 can change the luminance or color of the boundary region 430 according to the detection result of the detection unit 240. The detection unit 240 detects the illuminance and sends the detected illuminance to the display control unit 231.

  The display control unit 231 can change the luminance of the boundary region 430 to be higher or change the color to a brighter color as the illuminance detected by the detection unit 240 is lower. The low illuminance detected by the detection unit 240 indicates that the imaging unit 210 cannot capture sufficient light. Therefore, there is a high possibility that a dark subject is included in the imaging target. Therefore, the display control unit 231 increases the luminance of the boundary region 430 or changes the color to a bright color. With this process, the boundary between the display unit 110 and the frame unit 120 becomes clear. Therefore, it is possible to make the user clearly confirm the outer edge of the imaging target.

  The display control unit 231 can change the luminance of the boundary region 430 to be lower or change the color to a darker color as the illuminance detected by the detection unit 240 is higher. The high illuminance detected by the detection unit 240 indicates that the imaging unit 210 has taken in sufficient light. For this reason, there is a high possibility that a bright subject is included in the imaging target. Therefore, the display control unit 231 lowers the luminance of the boundary region 430 or changes the color to a dark color. With this process, the boundary between the display unit 110 and the frame unit 120 becomes clear. Therefore, it is possible to make the user clearly confirm the outer edge of the imaging target. Such a process is effective when the frame 120 has a light-colored region such as white.

  As another example, the display control unit 231 may change the luminance or color of the boundary area 430 based on an image displayed in an area adjacent to the boundary area 430. According to such processing, the brightness or hue of the boundary region is changed based on the image of the outer edge portion of the imaging target. Therefore, the boundary between the display unit 110 and the frame unit 120 becomes clear according to the image of the outer edge portion to be imaged. As an example, the display control unit 231 can change the luminance or color of the boundary region 430 to a luminance or color different from the image displayed in the region adjacent to the boundary region 430. The boundary between the display unit 110 and the frame unit 120 becomes clear by changing the luminance or color of the boundary region 430 to a luminance or color different from the image displayed in the region adjacent to the boundary region 430. Therefore, it is possible to make the user clearly confirm the outer edge of the imaging target.

  For example, the display control unit 231 may change the color of the boundary area 430 to a complementary color of an image displayed in an area adjacent to the boundary area 430. By changing to the complementary color, the boundary between the display unit 110 and the frame unit 120 becomes even clearer. The display control unit 231 may change the color of the boundary region 430 from the complementary color value of the image displayed in the region adjacent to the boundary region 430 to a color value within a predetermined range.

  Note that the display control unit 231 may change the luminance or color of each pixel constituting the boundary region 430 for each pixel, or may be unified so that the entire luminance and color of the boundary region 430 are the same.

  When changing for each pixel, the display control unit 231 compares the pixels constituting the boundary region 430 with the pixels in the region adjacent to the boundary region 430 and emphasizes the boundary region 430 so as to have different luminance and color. You may perform the process to do.

  On the other hand, in order to unify the entire boundary region 430 so that the same luminance or color is obtained, for example, the display control unit 231 receives the luminance histogram or the color histogram of the image from the control unit 220, and is included most in the image. You may perform the process which emphasizes the boundary area | region 430 so that it may become a brightness | luminance or color different from a brightness | luminance or a color.

  The display control unit 231 may emphasize the boundary region 430 by switching the display of each pixel constituting the boundary region 430 between ON and OFF and blinking.

  In addition, the display control unit 231 may divide the boundary region 430 by a predetermined unit and perform the above processing for each predetermined unit. The predetermined unit may be a unit for each pixel, a unit for a predetermined number of pixels, or a unit for all pixels constituting the image. Moreover, you may perform each control which was demonstrated above with respect to some pixels of each pixel which comprises the boundary area | region 430. FIG.

  Note that the width (inches or the number of pixels) of the boundary region 430 may be any width as long as the boundary is visible to the user as shown in FIG. In addition, the width of the boundary region 430 may be the same for the top, bottom, left, and right, or may be different.

  Until now, the example which changes the brightness | luminance or color of the boundary area | region 430 based on the illumination intensity detected by the detection part 240 or the image displayed on the display part 110 was demonstrated. However, it is not limited to such a form. In order to enhance the boundary region 430, the luminance or color of the boundary region 430 may be changed based on the relationship with the frame portion 120. For example, the color of the frame unit 120 is set in advance in a memory included in the control unit 220. Then, a process of changing the color of the boundary region 430 to a color different from the color of the frame portion 120 may be performed. As a typical process, the display control unit 231 changes the color of the boundary region 430 to a light color if the color of the frame 120 is a dark color, and the boundary if the color of the frame 120 is a light color. The color of the region 430 may be a dark color. Further, for example, the color of the boundary region 430 may be changed to a complementary color of the color of the frame portion 120. Also by such processing, the boundary between the display unit 110 and the frame unit 120 becomes clear. Therefore, it is possible to make the user clearly confirm the outer edge of the imaging target.

  Note that the display control unit 231 sets the boundary region 430 to, for example, white or blue regardless of the illuminance detected by the detection unit, the image displayed in the region adjacent to the boundary region 430, the color of the frame unit 120, and the like. It may be changed to a single color such as

  FIG. 6 is a diagram illustrating an example in which an instruction to execute the enhancement processing described so far is given from the user. For example, the display control unit 231 displays a message 650 on the display unit 110 asking the user whether to emphasize the boundary region. In the example of FIG. 6, a message “650 Confirm framing?” Is displayed. Here, when the user presses the message 650, the instruction is sent to the control unit 220 through the instruction receiving unit 260. In response to this instruction, the control unit 220 sends an instruction to execute the above-described process for enhancing the boundary region to the enhancement unit 230 (display control unit 231). As described above, a mode in which the user arbitrarily indicates whether or not to emphasize the boundary region may be employed. This message 650 may be displayed when the imaging unit 210 is activated and an image to be captured is displayed on the display unit 110, may be displayed on a predetermined setting screen, or may be displayed on the detection unit 240. It may be displayed when the detected illuminance is outside a predetermined range (when the illuminance is high or when the illuminance is low).

  FIG. 7 is a flowchart illustrating an example of a method for controlling the electronic device 100 according to the present embodiment. In step S710, the display control unit 231 determines whether a predetermined condition is satisfied. As described above, the predetermined condition is a condition such as whether an instruction from the user has been received or whether the illuminance is low. Of course, it is not limited to this example. The predetermined condition may be that the imaging unit 210 is activated.

  If the predetermined condition is satisfied in step S710, the process proceeds to step S720. In step S720, the display control unit 231 performs processing for emphasizing the boundary region between the display unit 110 and the frame unit 120. For example, the display control unit 231 performs a process of changing the luminance or color of the boundary area included in the display unit 110.

  As described above, in the present embodiment, the boundary area between the display unit 110 and the frame unit 120 is emphasized. With this process, the boundary between the display unit 110 and the frame unit 120 becomes clear. For this reason, when the user determines the imaging target while viewing the image displayed on the display unit 110, the user can clearly check the outer edge of the imaging target.

(Second embodiment)
In the first embodiment, an example in which the boundary region is included in the display unit has been described. In the present embodiment, an example in which the boundary area is included in the frame will be described.

  FIG. 8 is a diagram for explaining the outline of the enhancement processing performed by the enhancement unit in the present embodiment. The emphasizing unit performs processing for emphasizing the boundary region 830 between the display unit 110 and the frame unit 820. In the present embodiment, the boundary region 830 is included in the frame portion 820.

  In the frame portion 820 in the present embodiment, electronic paper is provided on the surface thereof. For example, electrophoretic electronic paper can be used. Some electronic papers switch between white and black, while others support full color. Electronic paper does not consume power during display, or requires very little power, and power consumption required for rewriting is small. It is as thin as paper. In the present embodiment, a mode in which the boundary region is emphasized by changing the luminance or color of the frame portion 820 will be described.

  FIG. 9 is a block diagram illustrating an example of the configuration of the electronic device 900 according to this embodiment. In addition, the same code | symbol is attached | subjected about the same structure as FIG. 2, and description is abbreviate | omitted. In the present embodiment, the emphasizing unit 930 includes a frame control unit 931 that controls the frame unit 820.

  As described above, the frame portion 820 is configured to include, for example, electronic paper. In the present embodiment, electronic paper may be provided on the entire frame portion 820, or electronic paper may be provided on a portion of the frame portion 820 adjacent to the display unit 110.

  The frame control unit 931 controls display of the frame unit 820. Specifically, display control of electronic paper provided in the frame portion 820 is performed. In addition, although this embodiment demonstrates the form by which the electronic paper is provided in the surface of the frame part 820, any form may be sufficient if a user can visually recognize that the display mode of the frame part 820 changes. . For example, electronic paper may be provided on the front surface of the frame portion 820, and a transparent film member or the like may be further provided on the surface.

  FIG. 10 is a diagram illustrating an example of a result of the enhancement processing performed by the enhancement unit 930 according to the present embodiment. The image (subject) displayed on the display unit 110 is the same as that described with reference to FIG. In the present embodiment, the luminance or color of the boundary region included in the frame unit 820 (the same region as the region of the frame unit 820 in the example of FIG. 10) is changed, so that the display unit 110 and the frame unit 820 are changed. The border area is highlighted.

  Note that the frame control unit 931 may change the luminance or color of the region adjacent to the display unit 110 instead of the entire region of the frame unit 820 provided with electronic paper. That is, the luminance or color of a part of the electronic paper provided in the frame portion 820 may be changed.

  Further, similarly to the processing described in the first embodiment, the frame control unit 931 can change the luminance or the color according to the detection result of the detection unit 240. The detection unit 240 detects illuminance and sends the detected illuminance to the frame control unit 931. The frame control unit 931 can change the luminance of the frame unit 820 (boundary region) higher or change the color to a brighter color as the illuminance detected by the detection unit 240 is lower. With this process, the boundary between the display unit 110 and the frame unit 820 becomes clear. Therefore, it is possible to make the user clearly confirm the outer edge of the imaging target.

  As another example, the frame control unit 931 uses a frame based on an image displayed in an area adjacent to the frame unit 820 in the display unit 110 (that is, an image displayed on the outer edge portion of the display unit 110). The luminance or color of the unit 820 may be changed. As an example, the frame control unit 931 can change the luminance or color of the frame unit 820 to a luminance or color different from the image displayed on the outer edge portion of the display unit 110. According to such processing, the boundary between the display unit 110 and the frame unit 820 becomes clear. Therefore, it is possible to make the user clearly confirm the outer edge of the imaging target. The frame control unit 931 may change the color of the frame unit 820 to a complementary color of the image displayed on the outer edge portion of the display unit 110.

  Alternatively, the frame control unit 931 receives the luminance histogram or color histogram of the image displayed on the display unit 110 from the control unit 220 so that the luminance or color is different from the luminance or color most contained in the image. The brightness or color of the frame portion 820 may be changed. That is, the luminance or color of the frame portion 820 may be determined based on the entire image displayed on the display unit 110.

  In addition, the frame control unit 931 may emphasize the boundary region by blinking the frame unit 820 (boundary region), or has no relation to the illuminance detected by the detection unit, the image of the outer edge portion of the display unit 110, or the like. In addition, the frame portion 820 (boundary region) may be changed to a single color such as white or blue.

  Note that the trigger for the emphasis process in the present embodiment and the electronic device control method in the present embodiment can be the same as those described in the first embodiment.

  As described above, in the present embodiment, the luminance or color of the frame portion 820 is configured to be changeable. Then, the boundary area can be emphasized by changing the luminance or color of the boundary area included in the frame portion 820. Such processing makes the boundary between the display unit 110 and the frame unit 820 clear. Therefore, it is possible to make the user clearly confirm the outer edge of the imaging target.
