An image freeze device comprising a still image output mode selector, a write signal generator for outputting a write signal corresponding to an operational state of the still image output mode selector, a counter for counting a number of column addresses and a number of row addresses when driven by a main clock signal and a number of synchronizing signals, address selectors for designating an area corresponding to the column address and row address outputted from the counter, and a memory for storing image data in an area designated by the address selectors when the memory is write-enabled by the write signal outputted from the write signal generator and for outputting the image data stored in the designated area when the memory is output-enabled by an applied field signal. In case a still image is needed, the image freeze device can selectively project the formerly projected image alone through an image display device. Meanwhile, in the case where the position of an object may be changed, or the projected image is shaken from an outer impact, the image freeze device can realize the exact still image by stopping the corresponding moving image.
