IMAGE SIGNAL PROCESSOR FOR GENERATING DEPTH MAP FROM PHASE DETECTION PIXELS, AND DEVICE HAVING SAME

摘要

Disclosed is an image signal processor comprising a central processing unit (CPU). The CPU receives position information and image data of phase detection pixels from an imaging device, extracts first phase detection pixel data and second phase detection pixel data from the image data by using the position information of the phase detection pixels, computes first phase graphs from the first phase detection pixel data while moving a first window, computes second phase graphs from the second phase detection pixel data while moving a second window, computes disparities of the phase detection pixels by using the first phase graphs and the second phase graphs, and generates a depth map by using the disparities.
