Patent ID: 8872931

Claim:
A camera module comprising: an image sensor configured to convert an optical signal received through a lens into an electrical signal and generate full-size image data; an image signal processing unit configured to calibrate and output the full-size image data; a first memory unit configured to periodically receive and store the full-size image data from the image signal processing unit via a system bus; a scaling unit configured to scale down the full-size image data received from the first memory unit via the system bus and periodically output scaled-down image data to a display device via a local bus; and an encoder configured to receive the full-size image data stored in the first memory unit via the system bus, convert it into a compressed file in a predetermined format, and output the compressed file upon opening of a shutter, wherein the full-size image data and the compressed file are transmitted through the same system bus, wherein the image signal processing unit comprises: an image signal processor configured to set exposure conditions for the full-size image data, set autofocus, and/or adjust white balance; an image calibrator configured to calibrate color shade and picture quality of the full-size image data; and a format converter configured to convert a format of full-size image data output from the image calibrator into a predetermined format, and wherein the format converter converts the full-size image data output from the image calibrator into first format full-size image data corresponding to the display device and into second format full-size image data corresponding to the encoder.
