<p>An image processing system capable of executing thinning with all the pixels used, and an image processing method, a recording medium, and a program. When a (1, 0, 1, 0, 1)/3 filter is set with green pixels in a first line used us target pixels in a horizontalcomponent low-pass filter, green pixels are multiplied by 1, red pixels are multiplied by 0, and a total of these pixel values is divided by 3 to thereby calculate a simple average of the target pixels and adjacent green pixels. When red pixels in the first line are used as target pixels, a simple average of the target pixels and adjacent red pixel is calculated in the same way. In the same way, green pixels and blue pixel in a second line are filtered. Since every three pixels of a horizontal component are thinned at a horizontal 1/3 thinning unit, a thinning pixel group composed of simple average values of every three pixels as target pixels and adjacent pixels of the same color is generated. This invention is applicable to digital cameras.</p> |
