  Hereinafter, the present invention will be specifically described with reference to the drawings showing embodiments thereof.

(Embodiment 1)
FIG. 1 is a diagram schematically illustrating the appearance of the display device 1 according to the first embodiment, and FIG. 2 is a block diagram illustrating the configuration of the display device 1. The display device 1 includes a display unit 14 including a liquid crystal panel or a PDP (Plasma Display Panel), and is connected to an image output device 2 that is a PC (Personal Computer) and used as a monitor. Hereinafter, the image output apparatus 2 is referred to as PC2. The image output apparatus 2 is not necessarily a PC.

  The display device 1 controls the respective components, a storage unit 11 that stores various information, an image input unit 12 that inputs an image from the PC 2, and performs an appropriate process on the input image and outputs it. The image processing unit 13 includes a display unit 14 that displays an image, a drive unit 15 that drives the display unit 14 based on an output image from the image processing unit 13, and an operation unit 16 that receives an operation from a user.

  The control unit 10 uses a CPU (Central Processing Unit) or MPU (MicroProcessing Unit). The control unit 10 reads out and executes the control program 1P stored in advance in the storage unit 11, thereby realizing a function of controlling each component unit, controlling each component unit, and executing arithmetic processing.

  The storage unit 11 uses a nonvolatile memory such as a flash memory (flash SSD (Solid State Drive)) or an EEPROM (registered trademark, Electrically Erasable Programmable Read Only Memory). In addition to the control program 1P, the storage unit 11 stores various types of information that the control unit 10 refers to in order to execute arithmetic processing. The storage unit 11 stores various information generated by the processing of the control unit 10.

  The image input unit 12 is an interface for inputting an image from the PC 2 as a digital signal, and is, for example, a DVI (Digital Visual Interface) or DisplayPort interface. It may be a USB (Universal Serial Bus) interface.

  The image processing unit 13 is an integrated circuit that performs image processing including color conversion and gamma correction processing suitable for the display unit 14 on the image input from the PC 2. As will be described later, the image processing unit 13 according to the first embodiment includes a plurality of integrated circuits for image processing for performing different types of gamma correction such as sRGB or DICOM, and is switched to perform any one of the image processing. Is possible.

  The display unit 14 is a liquid crystal panel, for example. In this case, the driving unit 15 is a liquid crystal driving unit that drives a liquid crystal element based on an output image from the image processing unit 13. The display unit 14 is not limited to a liquid crystal panel, and may be a PDP. In this case, the drive unit 15 is a PDP drive unit. The display unit 14 may be a touch panel type.

  The operation unit 16 is a button for operating an OSD (On Screen Display) provided at the lower part of the display unit 14. The operation unit 16 includes a power key, a selection (SELECT) key, “→ / ←” keys 161 and 162, a determination (ENT.) Key 163, and the like (see FIG. 6). The “→ / ←” keys 161 and 162 may be “+/−” keys. The user can select and determine various setting information on the OSD displayed on the display unit 14 via the operation unit 16. The operation unit 16 may be realized by a touch panel provided on the display unit 14 instead of the keys provided on the frame of the liquid crystal panel as illustrated.

  Details of functions realized by the respective components in the display device 1 configured as described above will be described. FIG. 3 is a functional block diagram illustrating functions realized by the display device 1 according to the first embodiment. The display device 1 includes an image processing unit 13 composed of a plurality of integrated circuits, a storage unit 11 that stores various types of information, and a control unit 10 in which an operation unit 16 executes software processing based on a control program 1P. The following functions are realized in cooperation.

  The control unit 10 functions as an area detection unit 101, an image quality switching execution unit 102, and an operation reception unit 103.

  The area detection unit 101 performs processing for separately detecting a mixed monochrome image area and a color image area based on the image data of the input image. Specifically, since the PC 2 employs a multi-window system and displays a rectangular GUI corresponding to each application as a window, the area detection unit 101 detects each window area, and each area is a monochrome area. Or whether it is a color area. The area detection unit 101 may further determine whether each area is a text (color / monochrome) display area. More specifically, the area detection unit 101 detects a window area related to the multi-window system by edge detection and frame (horizontal line segment pair and vertical line segment pair) detection. The window region detection method may be based on any algorithm. The area detection unit 101 may detect an area other than each window, for example, a background portion as a background, or exclude it from the detection target. The area detection unit 101 performs monochrome / color determination for each pixel in the window, and compares the number of monochrome pixels with the number of color pixels to determine whether the area is a monochrome image area or a color image area. The area detection unit 101 may exclude the area determined as the text display area from the monochrome / color determination target. The area detection unit 101 may calculate a histogram of the number of pixels for the color distribution in each window and determine whether the area is a monochrome image area or a color image area based on the histogram. The area detection unit 101 stores the coordinate information of the detected area and the monochrome / color discrimination result in the storage unit 11 as a detection result. Specifically, the detection result is information for identifying an area, for example, “A”, coordinate information of the area “A”, and a discrimination result for the area “A” (monochrome: 0 / color: 1). The coordinate information is information indicating the position of the detection area in the display unit 14. The coordinate information is, for example, the horizontal size as the X axis, the vertical direction as the Y axis with the upper left corner of the display unit 14 as the origin, the right side from the upper left corner to the positive X axis, and the lower side as the positive Y axis. The coordinate information is one unit. In addition, the area detection unit 101 associates with the detection result one or more of the area of the detected area, information used for determination (for example, the ratio between the number of monochrome pixels and the number of color pixels, or a calculated histogram). Is stored in the storage unit 11. The area identification information, coordinate information, discrimination result, area, and information used for discrimination, which are detection results, are stored as later-described area specifying information 111 after processing by an image quality switching execution unit 102 described later. Other than the above may be deleted from the storage unit 11.

  The area detection unit 101 executes the above-described process at a predetermined timing. In the first embodiment, the area detection unit 101 executes the above-described process every time a certain period elapses, for example, every 500 milliseconds elapses. The area detection unit 101 may perform the above-described processing each time an image refresh instruction is issued from the PC 2. The refresh instruction may be given every fixed period such as 30 milliseconds, or may be configured every time the image content is changed.

  Note that the function of the region detection unit 101 has been proposed by the applicant as a HybridGamma function. As described above, the detection target by the area detection unit 101 of the display device 1 in the first embodiment is each window of the multi-window system. However, the display device according to the present invention is not limited to this, and it is only necessary to divide and detect a region by a unit having a certain area where monochrome / color or the like can be determined.

  The image quality switching execution unit 102 recognizes each window area detected by the area detection unit 101 based on the detection result stored in the storage unit 11 and the area specifying information 111 and the image processing correspondence information 112 described below. Depending on the monochrome / color discrimination result or setting, first to third image processing units 131 to 133 (to be described later) are switched to execute image processing on the images in the window areas. In addition, the image quality switching execution unit 102 performs switching so that the image processing by the fourth image processing unit 134 is performed on the image in the target area when highlight display described later is performed. Note that the input image may not be subjected to any image processing of the first to fourth image processing units 131 to 134.

  The operation receiving unit 103 stores the region specifying information 111 and the image processing correspondence information 112 corresponding to the region specifying information 111 according to the content of the operation notified from the operation unit 16. For example, when one of the areas detected by the operation unit 16 is selected and the content of the image processing is changed, the operation reception unit 103 selects the area of the selected area, the number of monochrome pixels and the number of color pixels. , And one or more of the calculated histograms are stored as region specifying information 111. The area specifying information 111 is not deleted from the storage unit 11 after being processed by the image quality switching execution unit 102. At this time, the operation receiving unit 103 may store the area specifying information 111 including the coordinate information and the determination result as the detection result. Further, the operation reception unit 103 stores information for specifying the content of the changed image processing as the image processing correspondence information 112 in association with the region specifying information 111. Specifically, the image processing correspondence information 112 is identification information for a corresponding region, for example, identification information for identifying one of the region “A” and first to third image processing units 131 to 133 described later, for example, “001”. (DICOM) ".

  The image processing unit 13 includes first to fourth image processing units 131 to 134. Each of the plurality of image processing units includes a LUT (Look Up Table) for performing different gamma correction and performs correction processing. Of course, the first to fourth image processing units 131 to 134 may perform correction processing other than the respective gamma correction, filter processing, and the like. In the first embodiment, the first image processing unit 131 performs processing for obtaining a display effect in a gradation expression conforming to DICOM (Digital Imaging and Communication in Medicine), that is, a standard for medical images. The second image processing unit 132 performs processing for obtaining a display effect in gradation representation for sRGB (standard RGB), that is, a color image. The third image processing unit 133 performs a process for obtaining a display effect in gradation expression based on settings such as contrast, brightness contrast, and color temperature set by the user. The fourth image processing unit 134 performs processing for highlight display in a partial image area of the image input from the PC 2. Various methods can be considered for highlight display. For example, a translucent image is synthesized in a specific area.

  Of course, the number of integrated circuits included in the image processing unit 13 is not limited to four, and may include more than four, including overlapping types. For example, correction processing suitable for text display, correction processing suitable for reproduction display of moving images, correction processing suitable for display of still images, correction processing suitable for display of CAD (computer aided design) data, or 3D A plurality of integrated circuits that perform correction processes suitable for various image displays, such as correction processes suitable for image display, may be used. The difference in the type of correction processing is not limited to a difference in gamma correction, but may be a difference in other display effects such as a color space. In this case, the area detection unit 101 may have a function of detecting a corresponding area, and may be able to automatically select appropriate image processing.

  Next, processing realized by each function of the display device 1 will be described with reference to a flowchart. FIG. 4 is a flowchart illustrating an example of a processing procedure for monochrome / color setting reception executed by the display device 1 according to the first embodiment. The control unit 10 executes the following processing when any key of the operation unit 16, for example, the determination (ENT.) Key 163 is pressed.

  The control unit 10 detects pressing of the key of the operation unit 16 by the function of the operation reception unit 103, and temporarily stops processing every 500 milliseconds by the function of the region detection unit 101 (step S11).

  The control unit 10 reads the detection result from the latest region detection unit 101 from the storage unit 11 and selects one of the detected plurality of regions (step S12). Based on the coordinate information of the selected detection region, the control unit 10 performs image processing on the image of the selected region with the fourth image processing unit 134 so as to superimpose a specific image. Are highlighted (step S13).

  The control unit 10 determines whether or not the user has performed a selection operation and an image quality changing operation on the highlighted detection area (step S14). Specifically, the control unit 10 detects that the determination (ENT.) Key 163 has been pressed when the highlighted (ENT.) Key 163 is pressed for the highlighted region by the function of the operation receiving unit 103. Then, each time the “→ / ←” keys 161, 162 are pressed, the control unit 10 starts with the contents of the automatically determined image processing in order (or in reverse order) from the first to third image processing units 131. ... To 133 are cyclically selected, and when the enter (ENT.) Key 163 is pressed again, it is recognized that one of the first to third image processing units 131 to 133 is changed. The control unit 10 may cancel the process when the EXIT key or the like is pressed during the operation.

  When it is determined that the user has performed the selection operation and the image quality changing operation (S14: YES), the control unit 10 changes the content of the image processing to the selected image processing (step S15). The control unit 10 uses the function of the operation receiving unit 103 to select any one of the region identification information 111 of the selected region, that is, the highlighted detection region, and the first to third image processing units 131 to 133 after the change. The image processing correspondence information 112 for specifying the above is stored (step S16).

  The control unit 10 determines whether the setting is completed by pressing the EXIT key or the like by the function of the operation receiving unit 103 (step S17). When the control unit 10 determines that the setting has not been completed (S17: NO), for example, it is detected that the user simply presses the “→ / ←” keys 161 and 162 in the highlighted area. If so, the process returns to step S12 to select the next detection area corresponding to the pressed key (S12), and the subsequent processes are executed.

  When the control unit 10 determines that the setting has been completed (S17: YES), the control unit 10 resumes the process by the function of the area detection unit 101 (step S18), and ends the setting reception process.

  Next, a process in which image processing set by a user's operation is executed according to the processing procedure shown in the flowchart of FIG. FIG. 5 is a flowchart illustrating an example of a processing procedure executed when an image is displayed on the display device according to the first embodiment. The control unit 10 of the display device 1 according to the first embodiment repeatedly executes the following process every time 500 milliseconds elapse.

  The control unit 10 performs region detection processing by the function of the region detection unit 101 (step S21).

  The control unit 10 refers to the storage unit 11 by the function of the image quality switching execution unit 102, and determines the stored settings, that is, the presence / absence of the area specifying information 111 and the image processing correspondence information 112 (step S22). When the control unit 10 determines that there is a stored setting (S22: YES), the control unit 10 refers to the result detected in step S21 from the storage unit 11, and is specified by the area specifying information 111 of the storage unit 11. It is determined whether or not an area matching the area has been detected (step S23). At this time, the control unit 10 determines whether or not the coordinates, area, or information used for determination of the detected region match in consideration of a predetermined error range.

  If the control unit 10 determines that the corresponding region has been detected in step S23 (S23: YES), the function of the image quality switching execution unit 102 stores the corresponding detection region without depending on the determination result. The image processing based on the processed image processing correspondence information 112 is executed (step S24).

  With the function of the image quality switching execution unit 102, the control unit 10 executes image processing according to the color / monochrome discrimination result outside the corresponding detection area (step S25), and outputs the image after image processing (step S25). S26), the process is terminated.

  When it is determined that there is no image processing correspondence information 112 stored in step S22 (S22: NO), the control unit 10 executes image processing according to the monochrome / color discrimination result for each image in the detection area. (S25), the image after image processing is output (S26), and the process is terminated.

  If it is determined in step S23 that the matching area has not been detected (S23: NO), the control unit 10 determines that the image for which the image processing setting has been accepted has been hidden, and stores the stored settings. That is, the area specifying information 111 and the image processing correspondence information 112 are deleted from the storage unit 11 (step S27). Then, the control unit 10 causes each detection area to execute image processing according to the monochrome / color discrimination result (S25), outputs an image after image processing (S26), and ends the processing.

  In step S23, the control unit 10 may determine that the matching region is not detected for the first time when the matching region is not detected for a certain period of time. Further, even when the control unit 10 determines that a matching area has not been detected, the control unit 10 may store the stored setting in the storage unit 11 without deleting the setting. The control unit 10 may not delete the setting once stored in the storage unit 11 while the storage capacity of the storage unit 11 is sufficient. In this case, when the user hides the image once or hides the image by displaying another image on the front, and the image is displayed again after a lapse of time, the appropriate image processing set in the past is performed. It can be executed without re-setting.

  The process of accepting image processing settings from the user through such processing will be described using a specific example. 6 to 9 are explanatory diagrams schematically illustrating a process in which the setting is received by the display device according to the first embodiment. In particular, the PC 2 is a terminal device of a medical chart management system used in a hospital, and the display device 1 will be described with an example used as a monitor of the terminal device.

  6 to 8 each show an example of an image displayed in a window displayed corresponding to each application executed on the PC 2. Text is displayed on the left side of the display unit 14, four X-ray images are displayed in the upper center, a photograph of a part of the body is displayed in the lower center, and a blood vessel image is displayed on the right. ing. FIG. 9 shows an example in which the position of the image is changed. Although the text is still displayed on the left side of the display unit 14, the image of the blood vessel is displayed on the right side of the center. .

  In the examples shown in FIGS. 6 to 9, the control unit 10 detects and distinguishes between a region displaying a photograph of a part of the body and a region displaying a right image by the function of the region detection unit 101. Then, they are identified as “Area A” and “Area B” and stored in the storage unit 11. Then, the control unit 10 determines that only the “region A” is color by using the function of the region detection unit 101 and determines other regions as monochrome. At this time, the control unit 10 determines that the area where the text is displayed by the function of the area detection unit 101 as the text display area, and does not execute the specific image processing.

  FIG. 6 shows an example in which highlight display is performed when the user presses the enter (ENT.) Key 163 of the operation unit 16 while each image is displayed on the display unit 14. The control unit 10 selects the “area A” displayed as the only color image among the detected areas, and performs the “area” by image processing of the fourth image processing unit 134 based on the coordinate information of the “area A”. An image for superimposing on “A” and distinguishing from other regions is displayed. In the example illustrated in FIG. 6, specifically, the fourth image processing unit 134 represents a rectangle solid-colored with a specific color at the position indicated by the coordinate information of “Area A” and the area of “Area A”. Composite with a value of 0.5 (hatched area).

  By displaying as shown in FIG. 6, the user can recognize that “region A” has been determined to be a color image. Then, as shown below, when the user desires to display the image of the region B as a color image, this can be set.

  In FIG. 7, when a highlight is displayed as shown in FIG. 6, when the user selects another detection region by pressing the “→” key 161, the region B is highlighted. This is an example (hatching area). The control unit 10 selects the next “region B” in each detected region, and superimposes it on “region B” by the image processing of the fourth image processing unit 134 based on the coordinate information of “region B”. To display an image for distinguishing from other areas. Thereby, as shown in FIG. 7, “area B” is highlighted.

  As shown in FIG. 7, when the desired “region B” is highlighted, the user presses the enter (ENT.) Key 163 (or the select (SELECT) key) to display an image for “region B”. Processing settings can be made.

  8 is changed when the user presses the enter (ENT.) Key 163 and presses the “→ / ←” keys 161 and 162 with respect to the highlighted “area B” shown in FIG. This is an example of image processing. By depressing the “→ / ←” keys 161 and 162, the highlighted display corresponding to the first image processing unit 131 for the determined monochrome image is changed to the highlight corresponding to the second image processing unit 132 for the color image. Changed to light display. In FIG. 8, the change from the highlight display corresponding to the first image processing unit 131 to the highlight display corresponding to the second image processing unit 132 for the color image is indicated by the change in the type of hatching. ing. In FIG. 8, the types of hatching are changed and expressed, but specifically, the color of a rectangular paint to be synthesized with an α value of 0.5 may be changed. At this time, when the user presses the enter (ENT.) Key 163 again, the area specifying information (for example, area and histogram) 111 for specifying the area B in association with the identification information “B” of “area B” and the change Information “002” for identifying the subsequent second image processing unit 132 is stored as image processing correspondence information 112 in association with the identification information “B” of “region B”.

  FIG. 9 shows an example in which the set image processing is performed on an image that is displayed with its position moved after the change. In the example of FIG. 9, the position of the image image of the blood vessel is moved with respect to the examples shown in FIGS. Processing of the control unit 10 of the display device 1 at this time will be described.

  Even when the position of the image image is moved, the control unit 10 executes region detection processing as shown in the flowchart of FIG. 5, for example, a region for displaying text on the left side and a blood vessel image. Detect the image area. At this time, the area specifying information 111 and the image processing correspondence information 112 are stored in the storage unit 11 for the “area B” set as shown in FIG. Then, the control unit 10 identifies the blood vessel image as “region X” by the function of the region detection unit 101 and temporarily stores it in the storage unit 11. The control unit 10 compares the area and histogram, which are information used for the determination with respect to the “region X”, with the area and histogram of the region specifying information 111 stored in the storage unit 11, and considers the error range. It is determined whether or not to perform (S23). At this time, the control unit 10 determines that the numbers match, and causes the “region X” to execute image processing by the second image processing unit 132 set to “region B”.

  In this way, when images of different attributes such as monochrome images and color images are mixed and displayed on the same screen, image processing is performed on each image with priority given to the setting by the user over the automatic determination result, A display satisfying the user can be performed. In the above description, the monochrome image area and the color image area are detected, and the user can set image processing for each area. However, in the present invention, the text display area may be selectable and image processing may be set.

(Embodiment 2)
In the second embodiment, for an area for which image processing is set by user selection, the display device 1 updates the area specifying information 111 for specifying the detected area every time the area detecting process is performed. Thereby, each window corresponding to the application executed on the PC 2 is uniquely specified, and the area specifying information 111 corresponding to the specified window follows the change of the window.

  The configuration of the display device 1 in the second embodiment is the same as the configuration in the first embodiment except for the details of the processing by the control unit 10 shown in FIG. Accordingly, the same reference numerals as those in the first embodiment are assigned to the respective components, and detailed description thereof is omitted.

  FIG. 10 is a flowchart illustrating an example of a processing procedure executed when an image is displayed on the display device 1 according to the second embodiment. Of the processing procedures shown in the flowchart of FIG. 10, the same processing steps as those in the first embodiment shown in FIG. 5 are denoted by the same step numbers, and detailed description thereof is omitted. The control unit 10 of the display device 1 according to the second embodiment also repeatedly executes the following process every time 500 milliseconds elapse.

  When the control unit 10 determines that the detection result detected by the function of the region detection unit 101 detects a region that matches the setting stored in the storage unit 11 (S23: YES), it is stored. A certain setting, that is, the content of the area specifying information 111 is updated with the detection result of the selected detection area (step S31), and image processing is performed based on the image processing correspondence information 112 set in the detection area (S24).

  In step S31, specifically, the control unit 10 performs processing as follows. When the control unit 10 detects the “region X” by the region detection processing and determines that the “region X” matching the “region B” stored in the storage unit 11 is detected in step S23, The content of the area identification information 111 of “B” is updated with the detection result for “area X”. More specifically, for example, the control unit 10 applies coordinates (x = X2, y) to “area B” stored in the area specifying information 111 that is located at the coordinates (x = X1, y = Y1). When the “region X” at the position of “= Y2) is determined to be the“ region X ”coinciding with the“ region B ”, the region specifying information 111 of the“ region B ”is represented by coordinates (x = X1, y = Y1 ) To coordinates (x = X2, y = Y2).

That is, in the second embodiment, when “region X” is detected as shown in FIG. 9, if it is determined that “region X” matches the region specifying information 111 of “region B”, “region” X ”=“ region B ”. Therefore, even if the position, size, and display content of the window change until the application for displaying the blood vessel image shown in FIGS. "B" and follow the changes in the coordinate information, area, and color distribution information, and store these as area specifying information 111.
This is not necessarily the case in the first embodiment, and it is not necessary to set “region X” = “region B”. Color distribution information corresponding to the position, size, or display content of the window of “region B” at the time when image processing is set by the user may be stored as the region specifying information 111.
In this regard, in the display device 1 according to the second embodiment, when the position of the GUI window corresponding to the application is changed, when the size (area) is changed, or when the content of the image is changed, these Information is updated following changes. As a result, the user can set image processing in association with a GUI for displaying an image.

  The disclosed first and second embodiments are examples in all respects and should not be considered as restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
