Camera unit and multimedia information appliance including camera unit

A multimedia information appliance comprising:

• an image sensor receiving an optical signal from a lens unit and converting the optical signal into an electrical signal;
• an image signal processor converting the electrical signal into an image signal, the image signal processor comprising a first sub block controlling the image sensor and the lens unit, and a second sub block receiving the image signal from the first sub block and performing first processing of the image signal;
• an application processor receiving the processed image signal from the second sub block and performing second processing of the processed image signal;
• a frame memory connected to the second sub block and the application processor for storing the processed image signal from at least one of the second sub block and the application processor;
• an image display receiving the processed image signal from the application processor and displaying an image corresponding to the received image signal, wherein the image sensor and the first sub block are formed in a sensor chip not connected to the frame memory, and the second sub block and the application processor are formed in a processor chip connected to the frame memory;
• a data line transmitting the image signal output from the first sub block to the second sub block;
• and
• a control line transmitting processing results of the first sub block to the second sub block, and transmitting processing results of the second sub block to the first sub block.
