Multimedia information appliance

摘要

A multimedia information appliance includes a camera unit, an image display unit, and a multi-port memory. The camera unit includes an image sensor, an image signal processor, an application processor, and a multi-port memory. The image sensor is configured to receive an optical signal of a photographed image from a lens, and to convert the optical signal into an electrical signal. The image signal processor is configured to convert the electrical signal into an image signal, and to control the image sensor. The application processor is configured to process the image signal. The multi-port memory includes a plurality of data input/output ports and stores signals received from the image signal processor and the application process through different data input/output ports.
