Abstract: An image data processing method includes generating a data window comprising N rows and N columns using Bayer data from a pixel array, generating a red (R), green (G), blue (B) data of a center pixel in the data window, detecting an edge region in the data window, detecting a bright region in the data window, adjusting the R, G, B data using a suppressing gain factor if both of the edge region and bright region is detected, and outputting the adjusting R, G, B data as a result of an interpolating process.

Abstract: A dead pixel compensating apparatus includes, inter alia, a pattern generation unit generating a programmable test pattern including data with respect to at least one dead pixel; a register array storing the test pattern; a dead pixel compensation unit receiving the test pattern stored in the register array and performing a dead pixel compensation algorithm to output compensation data; and a determination unit comparing the test pattern and the compensation data to determine whether or not the dead pixel compensation algorithm has an error, wherein a dead pixel compensation algorithm for compensating for a dead pixel of an image sensor in image data supplied from the image sensor is tested.
