- FIG. 1 is a block diagram showing a first example of an electrophotographic frame according to an embodiment of the present invention.
- Screen front view showing display contents of display screen of first embodiment The flowchart which shows the function of the control part in 1st Example
- External appearance front view showing a second example of the electrophotographic frame according to the embodiment of the present invention Screen front view showing display contents of display screen 104 of the second embodiment
- FIG. 1 is a block diagram showing a first example of an electrophotographic frame according to an embodiment of the present invention.
- the electronic photo frame 2 has a display screen 4 made of square electronic paper, and image data stored in the storage unit 6 or the like is displayed under the control of the control unit 8.
- the storage unit 6 stores image data and also stores programs necessary for the function of the control unit 8 and temporary data necessary for control.
- the control unit 8 reads the image data from the storage unit 6 according to the program of the storage unit 6 and rewrites the image displayed on the display screen 4 by the driver 10. Since the display screen 4 is made of electronic paper, after image rewriting, the image is maintained and displayed even if the power supply is cut off. As a result, the electrophotographic frame 2 can display image data for a long time by driving the power source of the battery 5.
- the image data stored in the storage unit 6 can be received from the camera 14 or the like by the wireless communication unit 12 using a wireless LAN, Bluetooth (trademark), or the like.
- the wireless communication unit 12 can also receive image data from a mobile phone.
- the control unit 8 can also display image data stored in the external storage medium inserted in the storage medium slot 16. Further, the image data output from the storage medium slot 16 can be read into the storage unit 6 after being taken into the storage unit 6.
- the timer unit 18 provides time data to the clock displayed on the display screen 4 and also functions as a timer for determining the rewriting timing of the image displayed on the display screen 4.
- Image rewriting can be performed at an arbitrary timing by operating the operation unit 20 in addition to automatic rewriting by a timer.
- the operation unit 20 includes a manual operation switch provided on the electrophotographic frame 2 and an infrared light receiving unit that receives a remote control operation.
- the infrared light receiving unit can receive an operation signal from the camera 14.
- the electrophotographic frame 2 can be used to view a large screen image in which an image of the camera 14 is displayed on the display screen 4 by operating the camera 14. It becomes a device.
- the electrophotographic frame 2 is fixedly held on the holding pedestal 20 and has a configuration in which the orientation cannot be changed vertically and horizontally.
- the image data includes both horizontal and vertical images, but the display screen 4 is a square having a side length covering the longitudinal direction of the image, so the electrophotographic frame 2 or the display screen 4 itself is rotated. Even if it is not, it is possible to display both a horizontally long image and a vertically long image on the full screen without changing the size of the display image and without performing trimming. However, an empty space in which no image is displayed in the short direction of the image is generated on the display screen 4.
- the present invention performs control so that there is no sense of incongruity in the existence of this empty space and the switching between the horizontally long image and the vertically long image.
- FIG. 2 is a front view of the screen showing the display contents of the display screen 4 in FIG. 1, and specifically shows the presence of empty space in which no photographic image is displayed and the control of the sense of incongruity in switching between a horizontally long image and a vertically long image. It is.
- a horizontally long image 22 is displayed on the display screen 4, and an image comment 24 such as a photographing date and a title of a photographic image and a clock 26 are displayed in an empty space 23.
- the clock 26 is provided in an empty space that is not covered by a photographic image that is vertically or horizontally long.
- the clock 26 is always displayed at the same position regardless of the switching between the horizontally long image and the vertically long image, thereby producing a sense of unity and unity of the display screen 4.
- the background portion of the empty space 23 has an appropriate wallpaper design, so that the entire display screen 4 is produced so as to maintain a sense of unity without waste.
- FIG. 2B shows the display content of the display screen 4 rewritten from the horizontally long image 22 to the horizontally long image 28 and the image comment 30. This rewriting is performed so that the image 22 fades out and the image 28 fades in. Note that the display of the clock 26 is unchanged. As is clear from the comparison between FIG. 2A and FIG. 2B, there is no change in the overall layout in the case of rewriting horizontally long images.
- FIG. 2 (C) and 2 (D) show the state of rewriting when the vertically long image 32 is displayed next.
- the landscape image 28 is erased sequentially from the right end to the left side.
- fade-out of the landscape image 28 is started.
- the lower end is not initially displayed as shown in FIG. 2D, but is sequentially displayed on the lower end side by the animation effect as shown by the arrow 36.
- the layout is such that the upper left corners of the two images coincide with each other, and as is clear from the comparison between FIG. 2C and FIG.
- the layout of the part does not change.
- the image comment 38 is displayed after the vicinity of the right end of the horizontally long image 28 has completely disappeared. In conjunction with this, the image comment 30 of the horizontally long image 28 disappears.
- FIG. 2E shows a state in which the vertically long image 32 is completely rewritten as described above. During this time, as shown in FIGS. 2B to 2E, the display of the timepiece 26 remains unchanged.
- the empty space 23 in the state of FIG. 2E is an integral background of the same wallpaper design as the empty space 23 of FIG. 2A, and maintains an image of the same display screen. The integrity of the empty space 23 becomes noticeable when the empty space 23 appears temporarily on the right and lower sides of the display screen 4 as shown in FIGS. 2 (C) and 2 (D). This reduces the sense of incongruity when switching between landscape and portrait images.
- FIG. 2F shows the display content of the display screen 4 rewritten from the vertically long image 32 to the vertically long image 40 and the image comment 42. This rewriting is performed so that the image 32 fades out and the image 40 fades in. In this case, the display of the clock 26 is not changed.
- FIG. 2E and FIG. 2F there is no change in the overall layout even when rewriting vertical images. Note that the state of rewriting from a vertically long image to a horizontally long image can be understood by following the process from FIG. 2E to FIG. 2B in reverse. At this time, the directions of the arrows 36 and 34 are understood to be opposite directions.
- the position where the clock 26 is provided is not limited to the lower right, and may be any other upper right, upper left, or lower left.
- the position where the image is displayed is also changed. For example, when the clock 26 is provided at the upper left, the vertically long image is displayed near the right end of the display screen 4 and the horizontally long image is displayed close to the bottom end of the display screen 4. At this time, the lower right corner of each image is matched. What is always displayed in an empty space that is not covered by a photographic image regardless of whether the display image is portrait or landscape is not limited to the clock 26, but other time information such as the date and calendar of the month, It may be any design such as a flower or animal that is not related to time information. However, it is desirable to make the impression of a photographic image clear by making it coexist, and to make the impression that there is always a display.
- FIG. 3 is a flowchart showing the function of the control unit 8 in the first embodiment of FIG.
- the flow starts when the battery 5 is attached to the electrophotographic frame 2, and thereafter the function is continued as long as the power supply from the battery 5 continues.
- the display of the common image that is, the clock 26 is started in step S2, and the display continues thereafter.
- step S4 it is checked whether the automatic rewriting mode during sleep is set.
- This automatic rewriting mode during sleeping is a mode in which rewriting of a photographic image is automatically performed once a day during a sleeping time period such as early morning. This is useful when electronic paper, especially color electronic paper, with insufficient rewriting speed performance is used, and there is no change in the photographic image before going to bed, and the next morning when the photographic image is touched by the human eye. In this mode, rewriting has been completed.
- step S4 If the automatic rewriting mode during sleep is set in step S4, the process proceeds to step S6, and it is checked whether or not the set rewriting time (for example, 2 am) has been reached. If it is detected that the rewriting time has come, the process proceeds to step S8. On the other hand, if arrival of the rewrite time is not detected in step S6, the process returns to step S4.
- step S4 the release of the setting of the automatic rewrite mode during sleep is detected, or the rewrite time is reached in step S6. Unless detected, step S4 and step S6 are repeated.
- step S8 the next image is read from the storage unit 6 or the storage medium in the storage medium slot 16. Then, in the next step S10, it is checked whether the image is a vertically long image from the header portion of the read image data file. If the image is a portrait image, the process proceeds to step S12, and a process of rotating the read image by 90 degrees is performed. This is for displaying a vertically long image vertically as shown in FIG. Next, in step S14, the presence / absence of an image comment is checked. If there is a comment, the process proceeds to step S16 to perform a process of dividing and arranging the image comment. This is for dividing line breaks in the image comment 38 as shown in FIG. After the above, the process proceeds to step S18.
- step S14 If there is no image comment in step S14, the process proceeds directly to step S18. On the other hand, if the image is not a portrait image in step S10, the process immediately proceeds to step S18. This means that the photographic images 22 are arranged horizontally as shown in FIG. 2A and the image comments 24 are arranged continuously in a line as shown in the image data.
- step S18 display screen rewriting processing is performed based on the above processing.
- This process includes a process of rewriting the electronic paper on the display screen 4 based on a predetermined operation with the image data whose layout has been determined in steps S8 to S16, and a process of monitoring whether this process is completed.
- the process returns to step S4. Thereafter, step S4 to step S18 are repeated unless the cancellation of the sleep-time automatic rewriting mode is detected in step S4.
- step S4 the slide show mode is set, so that the process proceeds to step S20 to check whether or not the slide show rewriting time has come. If it is not detected that the rewriting time has been reached, the process proceeds to step S22 to check whether there has been a manual operation (including remote control operation) of the operation unit 20. When an operation is detected, the process proceeds to a slide show process in step S24. If it is detected in step S20 that the slide show rewrite time has been reached, the process immediately proceeds automatically to the slide show process in step S24.
- step S22 when the manual rewriting operation is not detected in step S22, the process returns to step S4, and unless the mode change to the sleeping automatic rewriting mode is detected in step S4, the slide show is repeated by repeating step S4, step S20 and step S22. Wait for the rewrite time or manual operation.
- FIG. 4 is a flowchart showing details of the slide show process in step S24 of FIG. This flow basically corresponds to steps S8 to S18 in FIG. 3, but since the image is being rewritten while a person is watching, more detailed processing is added so as not to feel uncomfortable.
- the next image is read from the storage medium in the storage unit 6 or the storage medium slot 16 in step S32.
- a check is made in the next step S34 as to whether or not the image is a vertically long image from the header portion of the read image data file. If the image is a portrait image, the process proceeds to step S36, and a process of rotating the read image by 90 degrees is performed. This is for displaying a vertically long image vertically as shown in FIG.
- step S38 corner alignment of the rotated portrait image is performed. This is to reduce the uncomfortable feeling of switching between the horizontally long image and the vertically long image, which is the process of matching the top left corner position of the vertically long image 32 with the top left corner position of the horizontally long image 28 in FIG.
- step S40 the presence / absence of an image comment is checked. If there is a comment, the process proceeds to step S42 to perform processing for dividing and arranging the image comment. This is for dividing line breaks in the image comment 38 as shown in FIG. After the above, the process proceeds to step S44. If there is no image comment in step S40, the process proceeds directly to step S44. On the other hand, if the image is not a portrait image in step S34, the process immediately proceeds to step S44. This means that the photographic images 22 are arranged horizontally as shown in FIG. 2A and the image comments 24 are arranged continuously in a line as shown in the image data.
- step S44 display screen rewriting is started based on the above processing.
- step S46 it is checked whether or not the image whose rewriting has started has been changed from the current image to the vertical and horizontal directions. This change includes both a change from the vertical position to the horizontal position and a change from the horizontal position to the vertical position. The case where there is no change means rewriting from a vertical position image to a vertical position image or from a horizontal position image to a horizontal position image.
- step S48 This means, for example, the start of an animation operation in which the horizontally long image 28 is sequentially erased from the right end to the left side as indicated by an arrow 34 in FIG.
- step S50 animation in of the next image is started. This means, for example, the start of an operation in which the lower end of the vertically long image 32 is not initially displayed as shown in FIG.
- step S52 fade-out of the current image is started, and fade-in of the next image is started in step S54.
- fade-in / out with animation is performed, and when there is no vertical / horizontal change, only fade-in / out is performed.
- FIG. 5 is an external front view showing a second example of the electrophotographic frame according to the embodiment of the present invention.
- the electrophotographic frame 102 has a display screen 104 made of square electronic paper inclined by 45 degrees, and is fixedly instructed to the holding pedestal portion 120 by the support columns 202 and 204. Accordingly, even in the second embodiment, the orientation of the display screen 104 cannot be changed vertically and horizontally.
- the internal configuration blocks are the same as those of the first embodiment of FIG.
- the horizontal arrangement direction of the display elements as the display device is the direction of the arrow 208.
- the horizontally long screen 22 is displayed by being rotated by 45 degrees with respect to the display screen 104 as a display device, whereby the long side is displayed in the horizontal direction.
- the display screen 104 that is isotropic in the vertical and horizontal directions and the edge that opposes the side of the photographic image is not parallel to the side of the photographic image, the photographic image is laid out at the center, thereby the short side.
- the image can be displayed on the display screen 104 only by rotating the image relatively 90 degrees without trimming and trimming.
- FIG. 6 is a front view of the screen showing the display content of the display screen 104 of FIG. 5 as described above. Regardless of whether it is a horizontally long image or a vertically long image, there is no sense of incongruity in the presence of empty space. This is specifically shown.
- the landscape image 28 is displayed on the display screen 104, and triangular empty spaces 210 and 212 are generated above and below the long side of the landscape image 28, respectively.
- triangular empty spaces 214 and 216 that are approximated to the left and right of the short side of the horizontally long image 28 are also generated.
- a row of image comments 30 is laid out in the empty space 212.
- FIG. 6B shows a case where the vertically long image 32 is displayed on the display screen 104.
- triangular empty spaces 214 and 216 are generated on the left and right sides of the long side of the vertically long image 32, respectively.
- triangular open spaces 210 and 212 that are also approximated above and below the short side of the vertically long image 32 are generated.
- the image comments in FIG. 6B are divided and distributed to both sides of the vertically long image 32 as the date 218 and the title 220, respectively. As a result, the empty space can be used naturally while maintaining the horizontally written image comment.
- the layout is adjusted so that the center of the image is the center of the display screen 104. Is no longer necessary.
- FIG. 7 is a flowchart showing functions of the control unit 8 (the hardware configuration of the block diagram is the same as that of the first embodiment of FIG. 1) in the second embodiment of FIG.
- the flow starts when the battery 5 is attached to the electrophotographic frame 102, and the function continues thereafter as long as the power supply from the battery 5 continues.
- display of a common image such as wallpaper is started in step S62, and the display continues thereafter.
- step S64 it is checked whether the automatic rewriting mode during sleep is set. If applicable, the process proceeds to step S66, and it is checked whether or not the set rewriting time has come. If it is detected that the rewriting time has come, the process proceeds to step S68.
- step S64 if arrival of the rewriting time is not detected in step S66, the process returns to step S64.
- step S64 it is detected in step S64 that the setting of the automatic rewriting mode during sleep is detected or the rewriting time is reached in step S66. Unless detected, step S64 and step S66 are repeated.
- step S64 determines whether the mode is the automatic rewriting mode while sleeping. If it is not detected in step S64 that the mode is the automatic rewriting mode while sleeping, the mode is the slide show mode, and the process proceeds to step S70 to check whether the slide show rewriting time is reached. If applicable, the process proceeds to step S68. On the other hand, if it is not detected in step S70 that the slide show rewriting time is reached, the process proceeds to step S72 to check whether a manual rewriting operation has been performed. If an operation is detected, the process proceeds to step S68. On the other hand, if an operation is not detected, the process returns to step S64. Thereafter, unless a setting change to the automatic rewriting mode during sleep is detected in step S64, step S64, step S70, and step S72 are repeated, and the slide show rewriting time comes or is manually Wait for operation.
- step S68 the next image is read from the storage unit 6 or the storage medium in the storage medium slot 16. Then, in the next step S74, it is checked whether or not the image is a vertically long image from the header portion of the read image data file. If it is a vertically long image, the process proceeds to step S76, a process of rotating the read image by 135 degrees is performed, and the process proceeds to step S78. This is for displaying the short side of the vertically long image horizontally as shown in FIG. On the other hand, if it is not detected that the image is a portrait image in step S74, it means that the image is a landscape image. Therefore, the process proceeds to step S80, the read image is rotated 45 degrees, and the process proceeds to step S78. This is for displaying the long side of the horizontally long image horizontally as shown in FIG.
- step S78 the presence / absence of an image comment is checked. If there is a comment, the process proceeds to step S82 to check whether the image is a portrait image. If the image is a vertically long image, a process of dividing and arranging the image comments is performed in step S84. For example, as shown in FIG. 6B, the image comment is divided, and the date 218 and the title 220 are divided and laid out to the left and right of the vertically long image. After the above, the process proceeds to step S86. On the other hand, if it is not detected in step S82 that the image is a vertically long image, the image is a horizontally long image, and the process directly proceeds to step S86. This means that the image comments 30 of the photographic image 28 are continuously arranged in one line without being divided as shown in FIG.
- step S84 the image comment data subjected to the above processing is rotated by 45 degrees, and the process proceeds to step S88.

- the image comments are unified horizontally regardless of whether the image is a horizontally long image or a vertically long image. This is to reduce the sense of incongruity. If the presence of an image comment is not detected in step S78, the process proceeds directly to step S88.
- step S88 it is checked whether or not the image is monochrome. If applicable, in step S90, a setting is made to add a delay to the rewriting speed of the display image, and the process proceeds to step S92. This is because a monochrome image on electronic paper can be rewritten more quickly than a color image with a larger amount of information. However, an intentional delay is added to the monochrome image rewriting speed, and the rewriting speed is increased. This is to match the rewriting speed of the color image. As a result, it is possible to prevent a sense of incongruity from occurring due to a difference in the image switching speed of the slide show when a color image and a monochrome image are mixed. If it is not detected in step S88 that the image is a monochrome image, since the image is a color image, the process directly proceeds to step S92.
- step S92 a display screen rewriting process is performed.
- This process is a process of rewriting the electronic paper on the display screen 104 with the image data whose layout has been determined in steps S68 to S80 based on a predetermined operation including the setting information in step S90, and this process is completed. Including the process of monitoring whether or not When the image is rewritten and step S92 is completed, the process returns to step S64. Thereafter, steps S64 to S92 are repeated.
