摘要
A camera module compresses image data and produces a thumbnail image of this image data in FIFO order (First In First Out) by several lines of the image so as to enable transmission of the image data to the host module while significantly decreasing the size of the frame buffer memory. This can be achieved by, for example, an electronic device, including: a camera module, which transmits the data acquired by photographing; and a host module, which receives the data; wherein the camera module alternately transmits a compressed small portion including the data made by compressing the small portion of the image data for one frame and a sub small portion including the data with the resolution of the small portion reduced.
