Abstract
A memory cartridge having a semiconductor memory for storing digital image data is provided with a D/A converter for converting digital image data read out of the memory into an analog video signal, and a display device for displaying an image represented by this video signal provided in a first embodiment of the present invention. In another embodiment, a memory cartridge having a semiconductor image memory for storing a plurality of frames of digital image data is provided with an image display device and a frame feed switch. Predetermined image data is read out of the image memory and the image represented by the data is displayed on the display device. Displayed images are shifted sequentially in response to imputs from the frame feed switch. Also disclosed is a digital still video camera which includes a memory cartridge having the display device that may be loaded. The camera has an opening which allows an image displayed on the display device to be seen from the outside when the cartridge is loaded in the camera. If the camera is arranged so that a picture just imaged by the camera is displayed on the display device, the user can check whether the desired picture has been pr…
