Abstract
A camera module includes 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, a scaling unit configured to scale down the full-size image data received from the first memory unit and periodically output scaled-down image data to a display device, and an encoder configured to receive the full-size image data stored in the first memory unit, convert it into a compressed file in a predetermined format, and output the compressed file upon opening of a shutter.
