Abstract

This invention discloses a color complementary interpolation method used in bel filter array images, which first of all inputs a 3x3 bel sample state region with a central pixel, then decides an example of complementary interpolation of a color filter according to the kind of the central pixel to get the mean and different values of the bel pixel at level and vertical directions then to complement the missed color elements to decide a pixel activity of the 3x3 bel pixel region, finally, when the activity is high, color elements having been complemented are selected in the low difference direction.

Description

technical field

[0001] The invention relates to a color interpolation method, in particular to a Bayer array interpolation method. The invention can be applied to an image processing device and an image processing method. Background technique

[0002] The human visual system has three types of cones: the long cone, the medium cone, and the short cone. The cones of vision can sense wavelengths corresponding to red, green and blue light, respectively. The visual cortex in the human brain can get signals from these three types of cones, and then perform interpolation to form a shaped image. The importance of the biological architecture of the human visual system lies in the dramatic conversion of the vast, entire visible spectrum to be processed into only the primary colors red, blue and green.

[0003] Therefore, the digital image sensor in a digital camera is also designed to be similar to the cone of vision of the human visual system. One of the most commonly used image ...
