METHOD FOR ACQUIRING IMAGE FRAME WITH IMPROVED NOISE CHARACTERISTIC

摘要

An image frame acquiring method with noise characteristics is provided to reliably remove noise of a still image by obtaining an average value from numerous image frames even when a buffer capacity is small. A plurality of image frames having a plurality of pixels are acquired by using a camera module(S110). Pixel values of the same coordinates of the plurality of image frames are averaged(S120). An average image frame having the plurality of average pixels is generated(S130). An image frame having a plurality of pixels is additionally acquired. The average image frame is updated with a new average pixel value obtained by averaging pixel values of the same coordinates of the average image frames and the additionally acquired image frame.
