ABSTRACT:
An interpolation method for generating pixel color is used for color generating of an array composed of red, green, and blue pixels so that each pixel has red, green, and blue components. After signals of the pixel array are received, the signal trends in the horizontal and vertical directions around pixels are first determined. Next, two pixels adjacent to each pixel are calculated along the direction of minimum variation to complement data of the pixel location using this calculated value. Subsequently, the lost blue or/and red component of each pixel is generated for pixels in the horizontal and vertical directions so that each pixel has red, green, and blue components. Accurate color interpolation can thus be provided to accomplish the effect of high and stable resolution.
