A digital image processing apparatus and a method of controlling the same. The digital image processing apparatus includes a multi-direction button as a shutter release button which can move an auto focus (AF) region while a first shutter release signal is being applied. The multi-direction shutter release button is operable along the first direction which is an up and down direction, and is operable in the multiple directions which include back, front, right, and left directions. Specifically, the multi-direction shutter release button is operable to apply a first shutter release signal when moved down along the first direction to a first position, to allow for auto focusing operations in accordance with movement in any of the multiple directions, and is operable to apply a second shutter release signal when moved down along the first direction to a second position to control the digital image processing apparatus to operate a shutter to capture an image.

A semiconductor memory device includes a refresh control circuit and a memory cell array. The refresh control circuit generates an internal auto refresh control signal based on a chip select signal and an external self refresh control signal. The memory cell array is refreshed in response to the internal auto refresh control signal. Because the semiconductor memory device internally generates the internal auto refresh control signal performing auto refresh operations, the semiconductor memory device may not be required to transmit to external devices for performing the auto refresh operations, and thus pins or pads for transmitting signals may be reduced and operation time may become faster.
