Abstract

Depth information is stored in a 2-port memory having a random port and a serial port. The depth information is read out from the serial port of the 2-port memory and is supplied to an integrated circuit. The integrated circuit performs pipeline processing by using the depth information read out from the 2-port memory. If write-in is necessary as a result of the pipeline processing, the processed depth information is supplied to the random port of the 2-port memory, and the depth information is stored once again in the 2-port memory.
