A digital zoom apparatus includes an SDRAM. The SDRAM is stored with YUV data so that horizontal 4 pixels are assigned to each of addresses. A zoom start pixel is specified by a CPU on the basis of a zoom magnification. A memory control circuit transfers two lines of YUV data to a line memory with reference to an address to which the zoom start pixel is assigned, and furthermore, transfers part of the YUV data to a register. The line memory and the register are stored with the YUV data so that one pixel is assigned to each of addresses. The YUV data held in the register is subject to a zoom process with reference to the zoom start pixel, whereby, a through image subjected to an enlargement zooming process is displayed on a display.
