Abstract
An image processing device includes a pixel value read out unit which reads out a pixel value of a target pixel, a pixel value change unit which changes a pixel value of a noticeable pixel, the noticeable pixel being at least one pixel of adjacent pixels adjacent to the target pixel, and a coordinate specify unit which specifies a position of the target pixel in an image, the target pixel having the noticeable pixel as the adjacent pixel. The pixel value of the noticeable pixel is changed.
Claims12
An image processing device comprising:
- a pixel value read out unit which reads out a pixel value of a target pixel;
- a pixel value change unit which changes the pixel value of the target pixel;
- and
- a coordinate specify unit which specifies a position of the target pixel in an image, the pixel value of the target pixel being changed.
An image processing device comprising:
- a pixel value read out unit which reads out a pixel value of a target pixel;
- a pixel value change unit which changes a pixel value of a noticeable pixel, the noticeable pixel being at least one pixel of adjacent pixels adjacent to the target pixel;
- and
- a coordinate specify unit which specifies a position of the target pixel in an image, the target pixel being adjacent to the noticeable pixel included in the adjacent pixels, the pixel value of the noticeable pixel being changed.
An image processing device comprising:
- an image filter which performs predetermined image processing to an input image;
- a pixel value read our unit which reads out a pixel value of a target pixel at a desired timing, the desired timing being from search start to search end when an objective position in the image processed by the image filter is searched by a target pixel;
- a pixel value change unit which changes the pixel value of the target pixel;
- and
- a coordinate specify unit which specifies a position of the target pixel in an image, the pixel value of the target pixel being changed.
