Electronic still camera, instant printer and instant film

摘要

Image data obtained through an image sensor is written in a memory. When printing an image, a printing head is driven in accordance with the image data read out from the memory in a line sequential fashion, and is synchronously moved in a sub scan direction, thereby exposing the instant film line by line. The image appears on the exposed instant film as a developing solution is developed by developing rollers while the instant film is advanced out through the developing rollers. Alternatively, the printing head is driven synchronously with the instant film being advanced. Thereby an image is printed at one sub scanning without the need for moving the printing head. The printing head is provided with an array of three color light emitting elements, and three color light beams are simultaneously projected onto the instant film. The electronic still camera is automatically set in an imaging mode when a power switch is turned on, and is switched to a display mode or a print mode as soon as a display mode key or a print mode key is operated. After being switched to the display mode, the electronic still camera is quickly switched to the imaging mode if only a shutter release button is operated.
