It is a figure which shows the camera for acquiring the image displayed on a digital photo frame. It is a figure which shows the binoculars for acquiring the image displayed on a digital photo frame.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  The first embodiment is an imaging device. 1A and 1B show a schematic appearance of the camera 10 according to the present embodiment. FIG. 1A is a rear view on the user side, and FIG. 2B is a side view on the right side when viewed from the user. Here, a digital still camera for still image shooting is assumed as the camera 10. The camera 10 of the present embodiment can also be applied to a digital still camera having a moving image shooting function and a digital video camera having a moving image shooting function as a main function.

  The camera 10 includes a photographing lens 11, an electronic viewfinder (hereinafter referred to as “finder”) 12 having a display element therein, and a back panel 13. A light beam incident from the photographing lens 11 is converted into an electric signal by an image sensor such as a CCD or CMOS, and is converted into an image signal by a signal processing unit. The image signal is subjected to image processing such as gradation correction, white balance processing, and noise reduction processing by an image processing unit. The image signal subjected to image processing is stored as image data in a storage medium, and is displayed as an image on the display element of the finder 12 and the rear panel 13. Note that the image sensor, the signal processing unit, the image processing unit, and the storage medium are not shown in FIG.

  The viewfinder 12 includes a diopter adjustment mechanism. When the user rotates the dial 12d provided on the back surface of the camera 10, at least one of the lenses constituting the eyepiece optical system of the finder 12 moves in the optical axis direction, and the diopter of the finder 12 is changed. The diopter of the finder 12 is detected by the diopter detection unit 21 based on the adjustment amount of the diopter adjustment mechanism.

  The back panel 13 is a display that is attached to the back of the camera 10 and displays characters such as a setting screen and shooting parameters in addition to images such as a through image and a captured image. Although the back panel 13 is comprised with a liquid crystal display, it is not limited to this, For example, an organic EL display can also be used.

  In addition to the normal operation button 14, an enlargement button 15 and a distance measuring sensor 22 are attached to the back of the camera 10. An acceleration sensor 23 is attached inside the camera 10.

  The enlarge button 15 is a button for changing the display mode of the back panel 13 (hereinafter, the display mode of the back panel 13 is simply referred to as the display mode). The enlargement button 15 is disposed near a part where the user holds the camera 10. When the user presses the enlarge button 15 when it is difficult to see the display on the rear panel 13, the display mode is changed according to the diopter of the finder 12.

  The distance measuring sensor 22 is a sensor that measures the distance between the back panel 13 and the user's face. The distance measuring sensor 22 is, for example, a sensor that measures the distance based on the position of the infrared light that projects infrared light onto the object to be measured and reflects back from the object to be measured. The acceleration sensor 23 is a sensor that detects acceleration in the front-rear direction of the camera 10, preferably in the direction perpendicular to the rear panel 13.

  When it is difficult for a hyperopic / presbyopic user to see the display on the back panel 13, the user often takes a specific action of moving the camera 10 (back panel 13) away from the face, for example. Any of the above sensors is used to detect such a specific action. When a specific operation is detected, the display mode is changed in accordance with the diopter of the finder 12 in the same manner as when the enlarge button 15 is pressed.

  Note that at least one of the enlargement button 15, the distance measuring sensor 22, and the acceleration sensor 23 may be provided in the camera 10.

  In addition, as a display mode, for example, in the case of the size of an image or a character, the standard size (standard mode), 1.2 times the standard size (enlargement mode 1), 1.5 times the standard size The size (enlargement mode 2), twice the standard size (enlargement mode 3), and the like. The display mode is changed such that the diopter of the finder 12 is 1 to 1.5 and the enlarged mode 1 and 1.5 to 2 the enlarged mode 2. As described above, the change between the standard mode and the enlargement mode (1, 2, 3) and the change between the enlargement modes correspond to “the display mode is changed”.

  Further, the enlargement ratio of images and characters may be linked to the diopter of the finder 12. In this case, there are two display modes, the standard mode and the continuous enlargement mode. Therefore, the change between the standard mode and the continuous magnification mode corresponds to “the display mode is changed”. In the continuous scaling mode, the size of images and characters changes continuously. The change in the continuous scaling mode also corresponds to “the display mode is changed”.

  FIG. 2 is a functional block diagram of a part related to processing for changing the display mode in the control unit of the camera 10.

  Signals from the diopter detection unit 21, the enlargement button 15, the distance measurement sensor 22, and the acceleration sensor 23 are input to the control unit 31. The signals from the enlargement button 15, the distance measuring sensor 22, and the acceleration sensor 23 may be at least one of these signals.

  The control unit 31 acquires the diopter value of the finder 12 (hereinafter simply referred to as diopter) from the diopter storage unit 32. Note that when the diopter adjustment of the finder 12 has not been performed yet, the diopter of the finder 12 is not stored in the diopter storage unit 32. In such a case, the control unit 31 prompts the user to perform diopter adjustment by display or sound. When the diopter adjustment is completed, the control unit 31 detects the diopter of the finder 12 by the diopter detection unit 21. The control unit 31 stores the detected diopter in the diopter storage unit 32 and uses it thereafter. The diopter storage unit 32 is configured by a non-volatile memory so that the diopter of the finder 12 can be stored even after the power is turned off.

  Further, assuming that the camera 10 is used by a plurality of users, the diopter of the finder 12 may be stored in the diopter storage unit 32 for each user. In this way, the diopter corresponding to the user currently in use may be selected.

  The control unit 31 determines whether it is necessary to change the display mode based on the input signal. When it is determined that the display mode needs to be changed, the control unit 31 instructs the display mode change unit 33 to change the display mode. The display mode changing unit 33 changes the display mode in accordance with an instruction from the control unit 31. By this change, an image / character enlarged at an enlargement ratio corresponding to the diopter of the finder 12 is displayed on the rear panel 13.

  FIG. 3 is a flowchart showing the contents of the program for changing the display mode. In FIG. 3, it is assumed that the user name is registered in advance. This program is stored in a storage device such as a RAM / ROM. The functions of the control unit 31 and the display mode changing unit 33 are realized by the CPU reading and repeatedly executing this program. The storage device and the CPU are provided in the camera 10, but are not shown in FIG. This will be described below.

  In S10, the user is prompted to select a user name. The user name is selected by, for example, displaying a user list registered in advance on the rear panel 13 and selecting the user's name from the list. If there is no user name, the user name is registered separately.

  In S11, it is determined whether or not diopter adjustment has been completed. Whether the diopter has been adjusted is determined, for example, based on whether the diopter of the finder 12 corresponding to the user currently in use is stored in the diopter storage unit 32. If it is determined that the diopter has been adjusted, the process proceeds to S15, and if not, the process proceeds to S12.

  In S12 to S14, diopter adjustment of the finder 12 is performed.

  In S12, a diopter adjustment image is displayed on the display element of the finder 12. The diopter adjustment image is an image suitable for the user to determine whether the image is in focus. As the diopter adjustment image, for example, an image including only luminance information including a plurality of intersecting lines as illustrated in FIG. 4 is used.

  In S13, the user operates the diopter adjustment dial 12d to adjust the diopter of the finder 12. When diopter adjustment is completed, the process proceeds to S14. Completion of the diopter adjustment is determined based on, for example, a user operation on the operation button 14.

  In S <b> 14, the diopter of the finder 12 is detected by the diopter detector 21. The detected diopter is stored in the diopter storage unit 32 together with the user name. When the above process ends, the process returns to S11.

  On the other hand, after S15, the display mode is changed and released according to the diopter of the finder 12.

  In S15, the diopter of the finder 12 corresponding to the user currently in use is selected from the diopter storage unit 32 and read out.

  In S16, it is determined whether or not the diopter of the finder 12 is on the plus side. A positive diopter means that the user is hyperopic or presbyopia. If it is determined that the diopter of the finder 12 is on the plus side, the process proceeds to S17, and if not, the process ends.

  In S17, the distance sensor 22 detects the distance between the back panel 13 and the user's face.

  In S <b> 18, the acceleration sensor 23 detects the acceleration of the camera 10.

  When the diopter is positive, the user is hyperopic or presbyopia. Therefore, when the image on the back panel 13 is viewed, a specific operation of moving the camera 10 (the back panel 13) away from the face is performed so that it is easier to see. Here, when the user moves without changing the position of the camera 10, a specific operation can be detected by the distance measuring sensor 22. On the other hand, when the user moves the camera 10 without changing the position, at least one of the distance measuring sensor 22 and the acceleration sensor 23 can detect a specific operation.

  In S19, it is determined whether a condition for changing the display mode (hereinafter referred to as “display mode change condition”) is satisfied. When a specific operation is detected in at least one of the distance measuring sensor 22 and the acceleration sensor 23, it is determined that this condition is satisfied. When the enlarge button 15 is used, a process for detecting that the enlarge button 15 is pressed is performed instead of the processes of S17 and S18. In this case, in S19, when the pressing of the enlarge button 15 is detected, it is determined that this condition is satisfied.

  The display mode change condition is established when a specific action (including both the operation on the camera 10 and the user's own action) that can be performed by a hyperopic / presbyopic user when the display on the rear panel 13 is difficult to see. Determined.

For example, based on the state of the enlargement button 15, the distance between the back panel 13 and the user's face, and the acceleration of the camera 10, it is determined whether the following state is satisfied. Then, when any one of the conditions is satisfied, it is determined that the display mode changing condition is satisfied.
(A) The enlarge button 15 is pressed.
(B) The camera 10 has moved away from the user's face, or the user's face has moved away from the camera 10. That is, the distance between the back panel 13 and the user's face has increased.
(C) The amount of movement of the camera 10 away from the user's face or the amount of movement of the user's face away from the camera 10 exceeds a predetermined value. That is, the amount of increase in the distance between the back panel 13 and the user's face exceeds a predetermined value with reference to the position of the back panel 13 before the display mode is changed (when control is started).
(D) The distance between the back panel 13 and the user's face exceeds a predetermined value.

  Note that it is not necessary to determine all whether or not these states (a) to (d) are satisfied. Moreover, you may make it determine states other than these (however, the specific operation | movement which a hyperopic / presbyopic user can take when the display of the back panel 13 is difficult to see) is reflected.

  If it is determined that the display mode change condition is satisfied, the process proceeds to S20. If not, the process proceeds to S21.

  In S20, the display mode is changed. Specifically, when an image is displayed on the rear panel 13, a part of the image (for example, a central region portion) is enlarged at a larger enlargement ratio as the diopter of the finder 12 is higher. When a character is displayed on the rear panel 13, the character size (font size) is enlarged with a larger enlargement factor as the diopter is positive. Further, the character spacing and line feed position are adjusted so that the enlarged characters do not overlap or protrude from the back panel 13.

  In addition, since it is thought that the user feels that it is hard to see the display of the back panel 13, so that the increase amount of the distance of the back panel 13 and a user's face and the distance between the back panel 13 and a user's face are large, these are considered. You may make it enlarge the enlargement ratio of an image and a character, so that a value is large.

  On the other hand, in S21, it is determined whether the display mode has been changed and a condition for canceling the change of the display mode (hereinafter referred to as “display mode change canceling condition”) is satisfied.

  The display mode change cancellation condition is that a specific action (including both operations on the camera 10 and the user's own action) that the user can take when the hyperopic / presbyopic user has recognized the display on the rear panel 13 is performed. It is determined that it has been established.

  For example, based on the distance between the back panel 13 and the user's face or the acceleration of the camera 10, the camera 10 has moved in a direction approaching the user's face, or the user's face has moved in a direction approaching the camera 10. When the determination is made, that is, when the distance between the back panel 13 and the user's face decreases, it is determined that the display mode change cancellation condition is satisfied.

  It is also possible to determine that the display mode change cancellation condition is satisfied when the user takes another action. For example, when the enlarge button 15 is pressed again, or when the distance between the back panel 13 and the user's face becomes smaller than a predetermined value, it may be determined that the display mode change cancellation condition is satisfied. .

  If it is determined that the display mode has been changed and the display mode change cancel condition is satisfied, the process proceeds to S22, and the display mode is restored. Otherwise, the process ends.

  Then, the effect by performing the said process is demonstrated.

  According to the above processing, the display on the back panel 13 is changed in accordance with the diopter of the finder 12 (particularly when the user is recognized as hyperopia / presbyopia). This improves the visibility and makes it easier to check. Specifically, since the image / character is enlarged at an enlargement ratio corresponding to the diopter of the finder 12, even if the user moves the camera 10 away when viewing the rear panel 13 with hyperopia or presbyopia, the rear panel 13 It becomes easier to check the display.

  Since the image / character displayed on the rear panel 13 is enlarged when the enlarge button 15 is pressed, the enlargement is performed only when the user needs to enlarge. Thereby, it is possible to prevent enlargement unintended by the user. Further, for example, it is possible to use such that the display is not enlarged when the entire atmosphere is viewed, and the display is enlarged by pressing the enlarge button 15 only when the user wants to see details.

  The enlargement of the image / character displayed on the back panel 13 is performed when the user increases the distance between the back panel 13 and the user's face. Since a hyperopic / presbyopic user is difficult to see nearby objects, the camera 10 is often moved away from the face or the face is moved away from the camera 10 so that the display on the rear panel 13 is easy to see. According to the above processing, the image / character displayed on the rear panel 13 is enlarged corresponding to the user's operation, so that it is displayed on the rear panel 13 without any special operation by the user. Enlargement of images / characters can be performed when needed.

  FIGS. 5A and 5B show how a hyperopic / presbyopic user is looking at the back panel 13. When the distance between the back panel 13 and the user's face is short as shown in FIG. 5A, it is difficult to see the display on the back panel 13, so the user stretches his arm as shown in FIG. Keep away from. At this time, if the display on the rear panel 13 is left as it is, images / characters appearing in the eyes are reduced, and visibility is lowered. However, according to the above processing, the image / character displayed on the rear panel 13 is enlarged, so that a reduction in visibility is suppressed.

  The enlargement of the image / character displayed on the back panel 13 is canceled when the user decreases the distance between the back panel 13 and the face. After confirming the images and characters displayed on the rear panel 13, the user often draws the camera 10 that has been far away, or brings the face closer to the camera 10. According to the above processing, since the enlargement of the image / character is canceled in response to such an operation of the user, when the user needs to cancel the enlargement of the image / character without operating the button or the like Can be done.

  The above process is performed when the diopter is positive. This is because the user moves the camera 10 away from the face when the back panel 13 is difficult to see, and the images / characters seen by the user become small and difficult to see, especially when the user is hyperopic / presbyopia. This is because is positive.

  Further, since the image and characters displayed on the rear panel 13 are enlarged based on the diopter of the finder 12, if diopter adjustment has not yet been performed, the display element of the finder 12 is used for diopter adjustment. Display the image and let the user adjust the diopter. Thereby, diopter adjustment can be performed easily and accurately.

  Since the detected diopter of the finder 12 is stored in the diopter storage unit 32, it is not necessary to adjust diopter every time. In addition, the diopter of the finder 12 is stored in the diopter storage unit 32 for each user, and the one corresponding to the user currently in use is selected from the diopter, so that the diopter adjustment is performed each time the user changes. There is no need to do it.

  The second embodiment is a display device. FIG. 6 shows a schematic appearance of the digital photo frame 40 according to the present embodiment. 7 shows a camera 42 and FIG. 8 shows a binocular 43 as an apparatus for acquiring an image to be displayed on the digital photo frame 40 and diopter information.

  The digital photo frame 40 includes a display panel 41. The display panel 41 displays images acquired by the camera 42 and the binoculars 43, as well as information other than images, such as characters. For this reason, the digital photo frame 40 includes a storage device that stores image and character information. Further, the digital photo frame 40 includes at least one of an enlargement button, a distance measuring sensor, and an acceleration sensor, like the camera 10 (first embodiment). In addition, the digital photo frame 40 includes a control unit that performs a display mode change process illustrated in FIG. 3 and a diopter storage unit that stores diopter information. In FIG. 6, illustrations other than the display panel 41 are omitted.

  Each of the cameras 42 (binoculars 43) includes a diopter adjustment ring 44. The user adjusts the diopter by turning the diopter adjustment ring 44. Here, the camera 42 (binoculars 43) has a diopter detection unit as in the camera of the first embodiment. Therefore, the diopter information after adjustment is detected by the diopter detection unit.

  The diopter information is sent from the camera 42 (binoculars 43) to the digital photo frame 40. Thereby, diopter information is taken into the digital photo frame 40. The diopter information is stored in the diopter storage unit. Diopter information may be stored for each user. The diopter information may be sent to the digital photo frame 40 alone, or the diopter information may be attached to the photographed image. Further, diopter information and images may be sent either by wire or wirelessly.

  As described above, the digital photo frame 40 includes at least one of an enlargement button, a distance measurement sensor, and an acceleration sensor. The digital photo frame 40 includes a control unit that performs a display mode change process. Therefore, the process shown in FIG. 3 is performed as in the first embodiment. In the digital photo frame 40, diopter information is sent from a camera 41 (binoculars 42). Therefore, the digital photo frame 40 does not include S11 to S14 among the processes shown in FIG.

  Since the processing content in the digital photo frame 40 has been described in the first embodiment, it is omitted here. In the first embodiment, a specific action that can be taken by a hyperopic / presbyopic user occurs when it is difficult to see the display on the rear panel 13 of the camera 10. In this embodiment, the display panel 41 of the digital photo frame 40 Occurs when the display is difficult to see.

  In the digital photo frame 40 of the present embodiment, the display mode of the display panel 41 is changed in accordance with the diopter of the finder 12 (particularly when the user is recognized as hyperopia / presbyopia), and thus is displayed on the rear panel. Visibility of images and characters is improved, making confirmation easier.

  The embodiment of the present invention has been described above, but the above embodiment shows an application example of the present invention, and is not intended to limit the technical scope of the present invention to the specific configuration of the above embodiment. Although the detailed description of the display device is omitted, various features of the imaging device also occur in the display device.

  For example, in the above embodiment, the finder 12 is electronic, but it may be optical. In this case, the diopter adjustment is performed according to whether the user can clearly see the frame or the like displayed in the viewfinder 12 instead of the diopter adjustment image.

  The display mode change mode of the rear panel 13 is not limited to the enlargement of the image / character. For example, the image / character may be highlighted.
