Embodiment approach 1

[0024] figure 1 It is a block diagram showing the configuration of the image processing device according to Embodiment 1 of the present invention. exist figure 1 Among them, the image processing device 1 according to Embodiment 1 is a device for color-converting a specific color a (first specific color) into a specific color b (second specific color) in an image of an input first image signal. Here, the first image signal is composed of RGB signals, and is image data displayed on a display screen of a display device (not shown) included in the image processing device 1 . In addition, the second image signal is image data obtained by color-converting the specific color a in the image of the first image signal into the specific color b.

[0025] The image processing device 1 according to Embodiment 1 includes a specific color specification unit 2 , a specific color information conversion unit 3 , and a color conversion unit 4 . The specific color specifying unit 2 is a compon...

Embodiment approach 2

[0049] image 3 It is a block diagram showing the configuration of an image processing device according to Embodiment 2 of the present invention. exist image 3 Among them, the image processing device 1A of Embodiment 2 is a device that converts exclusive colors other than the region of the specific color a specified in the image of the input first image signal into black and white. Here, the first image signal is composed of RGB signals, and is image data displayed on a display screen (not shown) included in the image processing device 1 . In addition, the second image signal is image data obtained by converting exclusive colors other than the region of the specific color a in the image of the first image signal into black and white.

[0050] An image processing device 1A according to Embodiment 2 includes a specific color designation unit 2 , a specific color information conversion unit 3 , and an exclusive color conversion unit 6 . The specific color specifying unit 2 is...

Embodiment approach 3

[0064] In Embodiment 1 and Embodiment 2 described above, a configuration is shown in which a specific color is designated from an image of the first image signal displayed on the display device. The configuration of the image processing apparatus according to Embodiment 3 is basically the same as that of Embodiment 1 or Embodiment 2 above, but the difference is as follows: In the specific color designation process performed by the specific color designation unit, In the color bar (color bar) of the image, specify a specific color.

[0065] Figure 4 It is a diagram showing a color bar used for specifying a specific color in the image processing device according to Embodiment 3 of the present invention. In the color bar 7 , hues are arranged in the order corresponding to the hue circle of the HSV system within the rectangular frame. In addition, in Figure 4 In , the color bar 7 is described in black and white in accordance with the regulations on the preparation of applicat...

Abstract

An image processing device includes: a particular color specification unit (2) which acquires respective RGB color component data on particular colors 'a' and 'b' from a display image (5) by a particular color specification mark; a particular color information conversion unit (3) which acquires a value H equivalent to hues of the particular colors 'a' and 'b' from the RGB color space by using the RGB color components of the particular colors 'a' and 'b'; and a color conversion unit (4) which color-converts a particular color 'a' into a particular color 'b' in the display image (5) according to the value H equivalent to the hues of the particular colors 'a' and 'b'.

Description

technical field [0001] The present invention relates to an image processing device for creating a special image of an input image. Background technique [0002] For example, Patent Document 1 discloses an image processing device that performs special effect processing on an input image to create a special image. As special effect processing performed by this device, there is a process of specifying a specific color from an input image, displaying a black and white image other than the specific color, or replacing a specific color (color A) with another specific color (color B ) image processing, etc. In a special effect of making a black and white image other than a specific color, for example, only the lip color of a woman's face can be left and the other colors can be grayed out to obtain an image in which a part of the image is emphasized. [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 2004-7370 [0004] In conventional image processing apparatu...
