Description

  The present invention relates to a color adjustment device, a color adjustment method, and a program. For example, the present invention relates to a color adjustment device, a color adjustment method, and a program that can adjust an input image to a color that does not cause a sense of incongruity.

  When an input image signal is displayed on a liquid crystal display device or the like, it is necessary to adjust the white balance of the image. Such white balance adjustment can generate white according to the input level or according to the user's preference by adjusting the R, B, and G signals as input signals.

  In addition, a technique is known in which a white balance is adjusted by preparing a plurality of light sources having different colors for illumination light of a display panel and adjusting the light amount of the light source without directly adjusting the color signal (for example, , Patent Document 1).

  In addition, the opening area on the front glass substrate side of the discharge cell in the plasma display panel is set to be different according to the brightness of each color, and appropriate white balance adjustment without reducing the gradation levels of the three primary colors of red, green and blue A technique capable of performing the above is also known (for example, Patent Document 2).

  Under such a technique, for example, in recent image display, there is a tendency that a white color temperature is set high in order to enhance a feeling of brightness, and a bluish white color is generated. Furthermore, it is also practiced to obtain a sharpness by further blueening the contour portion attached to the edge portion of the image.

JP 2001-135118 A JP 2001-126628 A

  However, the white color expressed by the above technique may be a white color that feels uncomfortable when compared with surrounding images. For example, the white color mixed in the background of the sunset, or the white color mixed in the entire lawn. Since such white color is far from the surrounding colors, it is very conspicuous and the overall image becomes uncomfortable.

  The present invention has been made in view of the above-described problems of the conventional white display method, and an object of the present invention is a new and improved adjustment capable of adjusting a white portion mixed in an input image to a coloring without a sense of incongruity. A chromatic adjustment device, a chromatic adjustment method, and a program are provided.

  In order to solve the above-described problem, according to an aspect of the present invention, a color component extraction unit that extracts a color component that is entirely biased in an image; and a pixel extraction that extracts a pixel having a white component in the image And a pixel adjustment unit that adjusts the color of the pixel having the white component so as to approach the biased color component. A color adjustment device is provided.

  The present invention (1) examines which color component the entire image is biased to, (2) extracts a white portion, (3) colors the white portion according to the color components of the entire image, It is characterized by the generation of an image without corresponding discomfort.

  The color component extraction unit samples an image for a predetermined time, integrates all color components of each pixel in each image, and extracts a color component having the highest appearance rate as a biased color component as a result of the integration. It is also good.

  The color component extraction unit integrates the color components of all pixels in order to derive overall color components of a plurality of images. A color component having a large absolute value of the accumulated color component can be regarded as a symbolic color component of the image. With this configuration, it is possible to extract a color component that is biased for a predetermined time, that is, occupies a predetermined area regardless of a change in time.

  The white component may be a color signal whose absolute value of the color difference signal Cb / Cr is within a predetermined range. Specifically, the absolute values of the color difference signals Cb and Cr may be within a predetermined range. As described above, the white component includes pure white and colors close to white.

  The biased color component may be represented by a color difference signal Cb / Cr, and the pixel adjustment unit may add the biased color component color difference signal Cb / Cr to the white component color signal.

  When the biased color component is represented by the color difference signal Cb / Cr, the pixel adjustment unit realizes a color shift by simply adding the color difference signal to the color signal of the pixel extracted by the pixel extraction unit. it can. With this configuration, it is possible to adjust the white portion mixed in the input image to a color that does not cause a sense of incongruity by simple calculation.

  In order to solve the above problems, according to another aspect of the present invention, there is provided a coloring adjustment method for adjusting the coloring of an input image: extracting color components that are biased entirely in the image; A coloring adjustment method is provided, wherein a pixel having a white component is extracted; and the color of the pixel having a white component is adjusted so as to approach the biased color component.

  Similarly, the computer extracts a color component extraction unit that extracts a color component that is generally biased in the image; a pixel extraction unit that extracts a pixel having a white component in the image; and a pixel having the white component A program is also provided that functions as a pixel adjustment unit that adjusts the color of the color so as to approach the biased color component. Furthermore, a storage medium storing such a program is also provided.

  As described above, according to the present invention, it is possible to adjust a white portion mixed in an input image to a color that does not cause a sense of incongruity.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the present specification and drawings, components having substantially the same functional configuration are denoted by the same reference numerals, and redundant description is omitted.

  When a video signal or the like is displayed on a display, the light quantity of R (Red), G (Green), and B (Blue) three primary color signals for each pixel constituting the image is adjusted. In particular, when expressing white, the three primary color signals must be added with a delicate balance (white balance adjustment).

  In this way, white that needs white balance adjustment tends to generate a bluish white by setting the color temperature of white to be high in order to enhance the brightness when displaying images in recent years. Furthermore, a process of obtaining a sharpness by further blueening the contour portion attached to the edge portion of the image is also performed. However, by the adjustment as described above, there may be a case where the white color becomes uncomfortable when compared with the surrounding image.

  FIG. 1 is an explanatory diagram for explaining an uncomfortable image. For example, FIG. 1 images a sunset scene. The white portion 100 mixed in the sunset background does not exist in the actual background, but is generated by processing the video. Since the white portion 100 is far from the surrounding colors, the white portion 100 is very conspicuous and the overall image becomes uncomfortable.

  In the embodiment of the present invention, (1) which color component the entire image is biased to is examined, (2) a white portion is extracted, (3) the white portion is colored according to the color components of the entire image, An image with no sense of incongruity corresponding to the image is generated.

(First embodiment: Color adjustment device)
FIG. 2 is a block diagram showing a schematic configuration of the color adjusting device 110 according to the first embodiment. The color adjustment device 110 includes an image input unit 120, a color component extraction unit 122, a pixel extraction unit 124, and a pixel adjustment unit 126.

  The image input unit 120 converts RGB signals constituting an image (video) into a luminance signal Y and a color difference signal Cb / Cr. When the input is not the RGB signal but the luminance signal Y and the color difference signal Cb / Cr, the image input unit 120 changes only the signal format, and the luminance signal Y and the color difference that can be processed in the color adjusting device 110. A signal Cb / Cr is generated.

  The color component extraction unit 122 uses the luminance signal Y and the color difference signal Cb / Cr converted by the image input unit 120 to extract color components that are biased as a whole in the image. Specifically, all the images for a predetermined time, for example, 30 frames per second are sampled, and all the color components of 720 × 480 pixels in each frame image are accumulated, and the most frequently appearing result is obtained. Color components with a high rate are extracted as biased color components. Here, 30 frames per second and 720 × 480 pixels of an image are used, but the present invention is not limited to this, and various values can be taken.

  FIG. 3A is an explanatory diagram for explaining extraction of color components of each pixel, and FIG. 3B is an explanatory diagram showing integration of the color components. The color signal of each pixel is represented by a luminance signal Y and a color difference signal Cb / Cr from the image input unit 120. Among them, only Cb and Cr which are color difference signals indicating color differences are extracted. Such Cb and Cr can be projected onto a two-dimensional plane as shown in FIG. 3A and replaced with a vector having a predetermined angle. For example, if the color difference signal Cb is a value x and the color difference signal Cr is a value y, the combined vector 200 is as shown in FIG. 3A, and the angle 202 is also derived as the ratio of the color difference signals Cb and Cr.

  If the angle 202 of the color signal for each pixel is obtained in this way, next, the color components of the entire image for one frame are integrated. For example, the color component indicated by the vector 200 in FIG. 3A is integrated in FIG. 3B, where the absolute value | C | of the color difference is 1 and the color angle is the angle 202. Such integration is continued for a predetermined time, for example, 30 frames.

  Thus, a color component having a high appearance rate is extracted from the integrated value of the color angles obtained as shown in FIG. 3B. For example, when the distribution of color components as shown by the curve 210 is shown, two color components can be targeted. However, when the angles between the two color components are separated and the absolute values of the angles are substantially equal, that is, when the difference between the absolute values of the peaks is equal to or less than a predetermined value β, the two color components are regarded as biased color components. Do not extract. This is because the object of this embodiment is achieved by a color difference signal in one direction.

  For example, when the distribution of color components as shown by the curve 212 in FIG. 3B is shown, only one color component protrudes. In this case, since the appearance rate of the one color component in the image for the predetermined time is high and the difference in absolute value from the other peak value is equal to or greater than the predetermined value β, the continuous screen group includes the color component. It can be thought that it is biased to. By extracting such a peak value, it is possible to limit the adjustment direction of the pixel adjustment unit 126 described later to one.

  In addition, for the color component that is biased, the color angle can be expressed by a color difference signal Cb / Cr. The color difference signal Cb / Cr extracted here is used by the pixel adjustment unit 126 described later.

  In the above description, the color component extraction unit 122 simply extracts a biased color component by accumulating color components for a predetermined time, but the method of extracting the biased color component is not limited to the above case. For example, the maximum value of the output of an LPF (Low Pass Filter) that receives the color signal of each pixel for each frame can be used as a biased color component.

  Such biased color components are not extracted for each image of one frame, but are extracted from an image accumulated to some extent when the color adjustment of this embodiment is performed in one frame or a short time near it. This is because the change is conspicuous, and on the contrary, the image becomes uncomfortable.

  The pixel extraction unit 124 extracts pixels having a white component in the image in the image input unit 120. This white component can also be represented by a color signal whose absolute value of the color difference signal Cb / Cr is within a predetermined range. For example, the luminance signal Y and the color difference signal Cb / Cr are represented by 8-bit digital values, the luminance signal Y of an arbitrary pixel is a predetermined value (for example, 16) or more, and the absolute value of the color difference signal Cb / Cr is a predetermined value. If (for example, 32) or less, the color of the pixel can be determined as a white component. Then, the pixel extracting unit 124 transmits the position information of the pixel determined to be the white component to the pixel adjusting unit 126 described later.

  The white component may be shown in a predetermined range near the center point of the CIE chromaticity diagram.

  FIG. 4 is an explanatory diagram showing a chromaticity diagram. In such a chromaticity diagram, a visible light color region (region surrounded by a curve) is indicated by positive parameters of chromaticity x and y, and the numbers carved on the solid line in FIG. The frequency of is engraved. In such a chromaticity diagram, with respect to two points on FIG. 4 corresponding to a certain two colors, the colors obtained by mixing (adding) the two colors at various ratios connect the corresponding two points on the xy plane. It is an internal dividing point of a line segment. That is, the point close to the outside is a color close to the primary color, and the color mixing property is higher as it is closer to the center point representing the white component.

  For example, if a triangle 280 is generated in FIG. 4 by connecting three points corresponding to RGB colors, the inner area is all the colors that can be expressed in RGB. In the chromaticity diagram, the complementary color of an arbitrary color is a point-symmetrical color with respect to the center point (white).

  In such a chromaticity diagram, the white component indicates a color in a predetermined range 282. The definition of the white component is not limited to the absolute value of the color difference signal Cb / Cr and the predetermined range 282 in the chromaticity diagram, and various ranges can be set.

  When the color component extraction unit 122 extracts a biased color component, the pixel adjustment unit 126 approximates the color of a pixel determined to have a white component by the pixel extraction unit 124 to the biased color component. Adjust as follows. For example, when the biased color component is represented by the sum of the color difference signals Cb / Cr, the pixel adjustment unit 126 adds the biased color component Cb ′ + Cr ′ to the white component color signal Y + Cb + Cr to perform coloring. It may be adjusted. In this case, the pixel having the white component is a color signal Y + Cb + Cb ′ + Cr + Cr ′.

  FIG. 5A and FIG. 5B are chromaticity diagrams for explaining a process of adjusting a pixel having a white component to a color that does not feel strange. For example, FIG. 5A shows an image showing a sunset background, and FIG. 5B shows an image showing a single lawn.

  In the case of FIG. 5A, since the image shows the sunset background, the color component extraction unit 122 extracts the red color 302 indicated by the wavy line as the biased color component. Therefore, the pixel adjustment unit 126 adds the biased color difference signal (color 302) in the red direction to the pixel having the white component 300, and performs color adjustment as indicated by the solid line arrow in FIG. 5A.

  Similarly, in FIG. 5B, since the image shows lawn, the color component extraction unit 122 extracts the green color 304 indicated by the wavy line as the biased color component. Therefore, the pixel adjustment unit 126 adds the biased green color difference signal (color 304) to the pixel having the white component 300, and performs color adjustment as indicated by the solid line arrow in FIG. 5B.

  FIG. 6 is an explanatory diagram showing an image when color adjustment according to the present embodiment is performed on the sunset background image in FIG. 1. In this way, it is possible to adjust the background of the sunset and the white color mixed in the grass on one side to a color that does not feel strange.

  Next, detailed processing of the color adjustment method for adjusting the color of the input image using the color adjustment device described above will be described.

(Second Embodiment: Coloring Adjustment Method)
FIG. 7 is a flowchart showing the flow of the coloring adjustment method in the second embodiment. Here, in particular, a process for extracting a biased color component in an image will be described.

  First, the image input unit 120 of the color adjusting device 110 converts the RGB signal of the input image (video) into a luminance signal Y and a color difference signal Cb / Cr. Then, the image converted into the luminance signal Y and the color difference signal Cb / Cr is transmitted to the color component extraction unit 122.

  The color component extraction unit 122 inputs one frame of the image processed by the image input unit 120 (S400), and sequentially inputs each pixel in the image (S402). Among the color signals of the extracted pixels, the value of the color difference signal Cb / Cr is acquired (S404), and the color difference signal Cb / Cr is replaced with an angle (color angle) on the color difference plane and integrated. (S406).

  Such integration of angles is performed for all pixels in the image. In other words, the processing from pixel input (S402) to angle integration (S406) is repeated (S408) until the angle integration processing for all the pixels in one frame is completed. The integration for each image is repeated by the number of frames for a predetermined time (S410). Accordingly, the angle integration (S406) is repeated by the product of one frame pixel and the number of sampling frames for a predetermined time.

  The color component having the highest appearance rate of the integrated color components is derived (S412), and is associated as a biased color component related to the image for a predetermined time.

  FIG. 8 is a flowchart showing the flow of the coloring adjustment method according to the second embodiment. Here, in particular, a process for extracting a pixel having a white component in an image will be described.

  The pixel extraction unit 124 inputs one frame of the image processed by the image input unit 120 (S450), and sequentially inputs each pixel in the image (S452). Among the color signals of the pixels thus extracted, the values of the luminance signal Y and the color difference signal Cb / Cr are acquired, and whether or not the luminance signal Y is greater than a predetermined value and the absolute value of the color difference signal Cb / Cr is It is determined whether it is within the predetermined range (S454).

  For example, if the luminance signal Y and the color difference signal Cb / Cr are represented by 8-bit digital values, the luminance signal Y of an arbitrary pixel is a predetermined value (for example, 16) or more and the absolute value of the color difference signal Cb / Cr is It is determined whether or not the value is a predetermined value (for example, 32) or less. If the above condition is satisfied, the color of the pixel is determined as a white component (S456), and the color information of the pixel indicates that it is a white component.

  Extraction of pixels having such a white component is performed for all pixels in the image. That is, the process from pixel input (S452) to white component determination (S456) is repeated (S458) until the angle integration process is completed for all pixels in one frame. In this way, all pixels having a white component in the entire image are extracted.

  In the coloring adjustment method according to the present embodiment, the color components that are biased as a whole in the image are extracted by the above-described processing, and pixels having a white component are extracted from the image. Based on the biased color component and the pixel having the white component, the color of the pixel having the white component is adjusted to approach the biased color component.

  By such a color adjustment method, it is possible to generate an image having no sense of incongruity corresponding to the input image.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.

  For example, in the embodiment described above, the biased color component is extracted by the integrated value of the angle of the color difference signal Cb / Cr. However, the present invention is not limited to this. When the value exceeds a predetermined value, the predetermined color component can be extracted as a biased color component.

  Further, in the extraction of the biased color components, each image is continuously integrated or input to the LPF, but a sudden change in the image such as a change in the image scene is detected, and the integrated value or The internal value of the LPF may be reset. With such a configuration, it is possible to prevent the white component pixels from being pulled to the past integrated value and becoming an image having a sense of incongruity.

  Note that the steps in the coloring adjustment method of the present specification do not necessarily have to be processed in chronological order according to the order described in the flowchart, but are performed in parallel or individually (for example, parallel processing or object-based processing). Processing).

  The present invention can be applied to a color adjustment device, a color adjustment method, and a program that can adjust an input image to a color that does not cause a sense of incongruity.
