US 9,313,378 B2 · Image processing apparatus and method of camera

Abstract

An image processing apparatus and method of a camera is provided for compensating for shutter lag. An image processing apparatus includes an image scaler which scales a camera output image to a viewing image, a buffer which buffers the camera output image, a multiplexer which multiplexes outputs of the image scaler and the buffer, an image processor which processes multiplexed images corresponding to the multiplexed outputs of the image scaler and the buffer, a demultiplexer which demultiplexes an output of the image processor so as to supply the viewing image to a display unit, a codec which encodes the camera output image output by the demultiplexer into a capture image, and a controller which controls the multiplexer and the demultiplexer in a time divisional manner within a frame duration such that the image processor processes the viewing and camera output image sequentially in a capture mode.
