The camera 11 may be configured to constantly capture the user's video while the image is being displayed. The camera 11 outputs the captured user video to the detection unit 21 of the control unit 20.

[0015] The display unit 12 is a device that displays various information. The display unit 12 is, for example, a liquid crystal display. LCD (Liquid Crystal Display) or OLED (E Displays include OLED (electro-luminescence) displays. The display unit 12 displays an image based on an image signal output from the display control unit 25 of the control unit 20. In this embodiment, the display unit 12 displays a plurality of interpreted images. The system displays an interpreted image with its brightness adjusted according to the user's line of sight.

[0016] The display unit 12 displays a plurality of images. The display unit 12 has a vertical or horizontal display screen. The display unit 12 may be one or more. The display units 12 are arranged without any gaps. The display units 12 may be arranged side by side, or may be spaced apart by a few centimeters. A different image may be displayed on each display unit 12. The images may be displayed side by side.

[0017] Displaying an image in multiple parts means displaying multiple images side by side so that they can be compared. Multiple images may be displayed with some overlapping as long as they can be compared.

[0018] The control unit 20 is, for example, a CPU (Central Processing Unit) The control unit 20 is a processing unit (control device) that is configured with the above. The control unit 20 loads the program into memory and executes the instructions contained in the program. The internal memory includes a memory not shown, and the internal memory is used for temporary storage of data in the control unit 20. The control unit 20 is configured to control the eye position of the user on the display unit 12 during image interpretation. The control unit 20 adjusts the brightness of the image to be read according to the gaze position information. The control unit 20 controls a detection unit 21, an area determination unit 22, a determination unit 23, The display control unit 25 includes a brightness adjustment unit 24 .

[0019] The detection unit 21 detects the user's gaze position on the display unit 12. Detect the user's gaze position on the display unit 12 on which an image is displayed in the image reading device 10 to be used In this embodiment, the detection unit 21 detects where the user is looking in the image. The detection unit 21 detects the user's gaze position on the image. The detection unit 21 acquires the user's image from the camera 11. The detection unit 21 performs image processing on the acquired user image to extract from the image of the user's eyes: The detection unit 21 detects the user's line of sight on the display unit 12. For example, the detection unit 21 detects the position of the user's pupils. and corneal reflection position, or the position of the user's eye corner and iris. Detecting the user's gaze using various techniques, such as detecting the gaze based on the position of In this way, the detection unit 21 obtains gaze position information indicating the position of the user's gaze on the image. Detects information.

[0020] The area determination unit 22 determines where the user's gaze is located in each of the areas into which the image is divided. The area determination unit 22 determines whether the image is in the state where the gaze position is detected by the detection unit 21. A gaze area is determined, which is an area on the image where the user's gaze is located. The method for determining the gaze area will be described below.

[0021] The area determination unit 22 divides the display screen of the display unit 12 into a plurality of areas, for example, and The area in which the line position exists may be determined and output as the gaze area. The determination unit 22 divides the display screen of the display unit 12 into a plurality of regions. The region determination unit 22, for example, The image displayed on the display screen of the display unit 12 is divided into a plurality of regions, and the position of the user's line of sight is displayed. The area determination unit 22 may determine an area in which the detection unit 21 is present and output the area as the line of sight area. It is determined in which area the detected gaze position is located. The area of ​​the area is calculated by the display unit 12. The size of the display screen or the size of the area of ​​the displayed image may be changed. For example, the area of ​​the region may be made larger as the area of ​​the display screen or image increases.

[0022] The area determination unit 22 determines, for example, a rectangular or circular area centered on the user's line of sight. The area of ​​a predetermined shape may be determined and output as the gaze area where the user's gaze position exists. The area of ​​the region of the predetermined shape is determined based on the size of the display screen of the display unit 12 or the size of the area being displayed. For example, when the display screen or image area is large, the image size may be changed according to the size of the image. The area of ​​the region of the predetermined shape may be increased.

[0023] For example, the area determination unit 22 determines an area that is specified by the user on the image by moving the line of sight. The area may be determined and output as the gaze area where the user's gaze position exists. 22 is a rectangle whose diagonal is the straight line along which the user moves his / her gaze on the image. The area may be determined as a gaze area where the user's gaze position exists, and output as such.

[0024] The area determination unit 22 determines an area in which the user's gaze position has remained for a predetermined threshold time or more. It may be output as a line of sight area.

[0025] The determination unit 23 determines whether the image displayed on the display unit 12 is a single image or a multiple image. 3, for example, when multiple images are displayed on one display unit 12, The determination unit 23 may determine that the image is displayed on each of the plurality of display units 12. If so, it may be determined that multiple images are being displayed.

[0026] The determination unit 23 determines whether the display unit 1 is in a normal or abnormal state based on the image signal output from the display control unit 25, for example. The determination unit 23 may determine that a plurality of images are displayed on the display unit 12. Image recognition is performed on the displayed image to detect frames that indicate the boundaries of the image and to distinguish between multiple images. The determination unit 23 may determine that the image is displayed on the display unit 12. Then, image recognition processing is performed on the image to determine that multiple images are being displayed based on the objects contained in the image. The determination unit 23 may, for example, determine whether the display unit Even if it is determined that multiple images are being displayed based on the number of images selected for display in 12, The method by which the determination unit 23 recognizes the number of images displayed on the display unit 12 is a known method. can be used and is not limited to.

[0027] The brightness adjustment unit 24 adjusts the brightness of the image according to the user's line of sight. When an area is specified in the image, the brightness is adjusted to lower the overall brightness of the screen from the initial state. More specifically, the brightness adjustment unit 24 adjusts the brightness when the determination unit 23 determines that a plurality of images are to be displayed. If it is determined that the user has gazed at the image, the The brightness adjustment unit 24 adjusts the brightness of the area to be focused on by the user. The brightness of the area specified by the user's line of sight is adjusted to be higher than the brightness outside the area. The brightness of the area outside the area is lowered below the brightness of the initial state when the image is displayed on the display unit 12. Then, when the user's gaze moves to another image, the original image before the gaze shift is adjusted. The brightness adjustment unit 24 then keeps the brightness adjustment as it is even when the user's line of sight moves. For the other images, the brightness of the area specified by the user's gaze is increased more than the brightness outside the area. In this way, the brightness of each region of the multiple images is increased.

[0028] The brightness adjustment unit 24 generates a control signal for controlling the brightness of the backlight of the display unit 12 . The brightness adjustment unit 24 outputs a control signal to make the brightness of the area higher than the brightness outside the area. When the brightness of the light is increased, the brightness of the screen when an image is displayed on the display unit 12 is increased. When the brightness of the backlight is reduced, the brightness of the screen when an image is displayed on the display unit 12 is reduced. become.

[0029] Alternatively, the brightness adjustment unit 24 generates an image in which the brightness of each pixel of the image is adjusted. The adjustment unit 24 generates an image in which the brightness of pixels in the image area is higher than the brightness of pixels outside the image area. In this case, the image whose brightness has been corrected by the brightness adjustment unit 24 is displayed by the display control unit 25. It is displayed on the display unit 12.

[0030] The brightness adjustment unit 24 resets the brightness of the image. If it is determined that the user's line of sight has moved, the brightness is reset. For example, When the user's gaze moves to another area in the image with the brightness of the adjusted area, The brightness of the image is adjusted according to the change in brightness of the image. When the user's gaze moves to another area with the brightness adjusted, the brightness of the area in multiple images is adjusted. Then, in the image where the gaze has moved to another area, the area pointed by the user's gaze is reset. The brightness of the specified area is increased and adjusted. Image brightness reset is the initial image brightness. It is to restore it to its original state.

[0031] The display control unit 25 controls the display unit 12 to display a plurality of images. The display control unit 25 controls the display unit 12 to display an image divided into a plurality of parts. For example, the image is controlled so as to be displayed in a plurality of parts on one display unit 12. In other words, the display control unit 25 displays a plurality of images side by side on one display unit 12, for example. The display control unit 25 controls the display units 12 to display, for example, The display control unit 25 controls the brightness adjustment unit 24 to display a different image. The display control unit 25 controls the display unit 12 to display the image. Output a signal.

[0053] In the present embodiment, the user does not need to operate the input device, but can select the image by the user's line of sight. According to this embodiment, it is possible to intuitively specify an area. Cut.

[0054] [Second embodiment] 7 to 9, an image reading apparatus 10 having a control unit 20A according to this embodiment will be described. FIG. 7 shows an image reading apparatus 10A having a control unit 20A according to the second embodiment. FIG. 8 is a block diagram illustrating another example of an image displayed on the display unit 12. 9 is a flow chart showing an example of a process in the control unit 20A according to the second embodiment. The image reading device 10A has the same basic configuration as the image reading device 10 of the first embodiment. In the following description, the same components as those in the image reading device 10 are designated by the same reference numerals or symbols. The control unit 20A of this embodiment is The present embodiment differs from the first embodiment in that it includes a measuring unit 26A and in the processing performed by a brightness adjusting unit 24A.

[0055] The distance measurement unit 26A measures the distance between the areas designated by the user's line of sight for each image. In this embodiment, the distance measurement unit 26A measures the distance between the area When the distance between the regions is specified, the distance between the regions is measured. The distance between the points where a line connecting the centers of the regions intersects the boundary of each region may be measured.

[0056] When the distance is equal to or greater than a threshold value, the brightness adjustment unit 24A connects the respective regions of the multiple images. More specifically, the brightness adjustment unit 24A adjusts the brightness by increasing the measurement value of the distance measurement unit 26A. Based on the result, if the distance is equal to or greater than a threshold, the image is pointed to by the user's gaze. The brightness of the specified area and the area connecting it is increased and adjusted. If the distance is greater than or equal to the threshold, In this case, when the user's gaze moves between the areas, it passes through a dark area, which causes pupil accommodation. In order to compare multiple regions, it is necessary to compare without pupil accommodation in order to see the differences more clearly. Therefore, in order not to adjust the pupil, when the distance is equal to or greater than a threshold, the user Adjust the brightness by increasing the area through which the line of sight passes.

[0057] If the areas of multiple images are the same height on the display screen, the area will be displayed horizontally across the multiple images. The area between the areas extending in the same direction is adjusted by increasing the brightness. When the heights of the images are different, the brightness of the area between the areas that extend diagonally across the images is It is raised and adjusted.

[0058] The threshold value is set based on the size of the display screen of the display unit 12 or the size of the area of ​​the displayed image. For example, a threshold may be set for each user who compares images.

[0059] Another example of the image 100 displayed on the display unit 12 will be described with reference to FIG. In this state, the area is specified by the user's line of sight E. The brightness of the image 100 is adjusted by lowering the overall brightness. The specified upper left area 1001P of image 1001 and the upper left area 1002 of image 1002 The brightness of P and the area connecting it has been adjusted to be higher.

[0060] Next, the process in the image reading device 10A will be described with reference to FIG. The processes in steps S1 to S126 and steps S130 to S134 are shown in FIG. Steps S101 to S106, S107 and S109 of the flowchart shown in FIG. Then, the same process as that in step S111 is carried out.

[0061] The control unit 20A measures the distance between the regions (step S127). The distance measurement unit 20A measures the distance designated by the user's line of sight for a plurality of images by the distance measurement unit 26A. Control unit 20A measures the distance between the detected regions. Then, control unit 20A proceeds to step S128.

[0062] The control unit 20A determines whether the distance is equal to or greater than a threshold (step S128). In detail, when the control unit 20A determines that the distance is equal to or greater than the threshold value (step S128), If the control unit 20A determines that the distance is equal to or greater than the threshold value, the process proceeds to step S129. If not (No in step S128), the process proceeds to step S130.

[0063] When it is determined that the distance is equal to or greater than the threshold value (Yes in step S128), the control unit 20A Then, the control unit 20A connects the areas and adjusts the brightness (step S129). The brightness adjustment unit 24A adjusts the brightness of the area designated by the user's line of sight relative to other images. The brightness of the area that connects the area that has been retained and the original image before the gaze movement is adjusted. Control unit 20A proceeds to step S131.

[0064] In step S129, the display unit 12 displays, for example, an image 1001 and Image 1002 is displayed. The upper left area 1001P of image 1001 and the upper left area 1002 of image 1002 are The brightness of area 1002P and the area connecting these areas has been adjusted to be higher.

[0065] As described above, in this embodiment, the distance between the areas designated by the user's line of sight is set to a threshold value. If the number is more than this, the brightness of the connecting area can be increased and adjusted. According to the study, when a user moves their gaze between two areas to compare two images, the brightness of the two images changes. Since there is no pupil adjustment, comparisons can be easily made.

[0066] [Third embodiment] 10 and 11, the image reading apparatus 10 having the control unit 20B according to this embodiment will be described. FIG. 10 is a diagram showing a configuration of a radiology apparatus 10 having a control unit 20B according to a third embodiment. FIG. 11 is a block diagram showing a configuration example of a control unit 20B according to a third embodiment. 10B is a flowchart showing an example of a process performed in the first embodiment. In the following description, the same components as those of the image reading device 10 will be used. The elements are denoted by the same or corresponding reference numerals, and detailed description thereof will be omitted. The control unit 20B has a pupil measurement unit 27B and the processing in the brightness adjustment unit 24B is different. This is different from the first embodiment.

[0067] The pupil measurement unit 27B measures the size of the user's pupil. 7B measures the size of the user's pupils from the user's image captured by the camera 11. The method of measuring the size of the user's pupils from the image can be a known method, and is not limited. do not have.

[0068] The brightness adjustment unit 24B adjusts the brightness of each area designated by the user's line of sight for a plurality of images. When the pupil size exceeds a threshold while alternating between the two images, the user is unable to see the images. The brightness of the area that is connected to the area specified by the user's line of sight is increased and adjusted. The focus adjustment unit 24B detects the focus of the image specified by the user's line of sight when the detection unit 21 detects the focus of the image specified by the user's line of sight. The movement of the line of sight between the respective regions is detected, and the measurement result of the pupil measurement unit 27B is If the size of the pupil exceeds a threshold, the brightness of the connecting area is increased and adjusted.

[0069] When the size of the user's pupil exceeds a threshold, pupil accommodation is taking place. To allow for comparison of multiple images without adjustment, the user is automatically deactivated when the pupil size exceeds a threshold. Increase and adjust the brightness of the area the user's line of sight passes through.

[0070] The threshold value of the pupil size may be, for example, a predetermined size. The size threshold is set based on the size of the pupil when viewing an image with normal brightness, for example. The size may be set to a predetermined ratio or more.

[0071] Next, the process in the image reading device 10B will be described with reference to FIG. The processes in steps S41 to S147 and steps S151 to S154 are shown in FIG. Steps S101 to S107, S108, etc. in the flowchart shown in FIG. Alternatively, the same process as that in step S111 is carried out.

[0072] The control unit 20B measures the size of the pupil (step S148). The control unit 20B measures the size of the user's pupils using the pupil measurement unit 27B. B proceeds to step S149.

[0073] The control unit 20B determines whether the size of the pupil exceeds a threshold value (step S149 More specifically, when the control unit 20B determines that the size of the pupil exceeds the threshold value ( If the result of the determination in step S149 is Yes, the process proceeds to step S150. If it is not determined that the threshold value is exceeded (No in step S149), the process proceeds to step S151 .

[0074] When it is determined that the pupil size exceeds the threshold value (Yes in step S149), the control unit 20B connects the regions and adjusts the brightness (step S150). 0B is a brightness adjustment unit 24B that adjusts the brightness of a plurality of images according to the user's line of sight. The control unit 20B adjusts the brightness by increasing the brightness of the portion where the regions are joined. Then, the process proceeds to step S151.

[0075] In step S149, the display unit 12 displays, for example, an image 1001 and Image 1002 is displayed.

[0076] As described above, in this embodiment, the image is selected based on the user's line of sight. When alternating between the regions, if the pupil size exceeds a threshold, the brightness of the area connecting the regions increases. According to this embodiment, the user's line of sight can be adjusted by increasing the degree of focus. Since there is no difference in brightness when the light is turned on, the change in pupil size can be reduced.

[0077] The components of the image reading apparatus shown in the figure are conceptual and functional, and are not necessarily physically the same as those shown in the figure. In other words, the specific form of each device is not limited to that shown in the drawings. Depending on the processing load and usage status of each device, all or part of the device can be operated in any unit. The services may be distributed or integrated, either locally or physically.

[0078] The image reading device is configured, for example, as software, with programs loaded into memory. In the above embodiment, the above hardware or software is implemented. These functional blocks are explained as being realized by cooperation. The following may be implemented using hardware only, software only, or a combination of both: This can be realized in a variety of ways.

Furthermore, the above-described configurations can be appropriately combined. Various omissions, substitutions, or modifications of the configuration are possible without departing from the scope of the present invention.

[0080] In the process of the flowchart shown in FIG. 9, the determination in step S126 is Yes. After that, step S130 may be executed before proceeding to step S127. In this case, After adjusting the brightness of the other image regions in step S130, the brightness between the regions is adjusted in step S127. Distance may also be measured.
