Apparatus for demosaicing colors and method thereof

Abstract

An apparatus and method for demosaicing colors in an image sensor can accurately locate edge directionality by detecting a successive 1-line edge precisely. The embodiments may include an image sensor containing information on a color signal detected from each pixel, a first line memory receiving and storing output data from the image sensor, a missing green information extractor extracting missing green pixel information from the data of the first line memory, a delayer receiving the data of the first line memory, the delayer delaying the received data for a prescribed duration, the delayer outputting the delayed data, a second line memory temporarily storing the data outputted from the missing green information extractor and the data provided via the delayer, and a missing red/blue information outputter extracting missing red/blue information from the data of the second line memory.
