Filed: 1999-03-16
Abstract: PROBLEM TO BE SOLVED: To shorten the time required for recording and to simplify the constitution. SOLUTION: An electronic still camera 10 is constituted of an image pickup part 15 and a printer part 30. The printer part 30 is constituted of a multiple light emission head 31 and a feeding-out part 32. The head 31 is constituted of a red light emission array, a green light emission array and a blue light emission array. The images of respective color printing light beams emitted from the respective light emission arrays are formed at an identical line on a photosensitive surface by a microlens array unit. While an instant film 28 is fed out by the feeding-out part 32, the respective light emission arrays are driven synchronously with the feeding-out action of the film 28. Then, the feeding speed of the film 28 is detected by a speed sensor.  By controlling the light emission timing of the liquid crystal arrays according to the feeding speed, the fluctuation of density caused by feeding irregularity is suppressed.
