BILINEAR INTERPOLATION CIRCUIT FOR IMAGE AND METHOD THEREOF

摘要

Disclosed herein are a bilinear interpolation circuit for an image and a method thereof. The bilinear interpolation method for ran image according to an exemplary embodiment of the present invention includes: increasing an input clock of a camera two times by a PLL; reading a plurality of reference pixels to be interpolated from the memory while storing input images (pixels) in the memory by the memory control unit, matching a clock timing increased two times; calculating pixel values to be corrected by an arithmetic operation by the data interpolation unit based on the read pixel (image) data; and outputting the calculated pixel values to be corrected by the output format conversion unit, matching an original clock speed.
