IPC: H04N5/369
Filed: 1997-10-09
Abstract: PROBLEM TO BE SOLVED: To provide the method for maximize the S/N for each color in a color image forming device. SOLUTION: In order to improve the S/N, an exposure time with respect to each color channel is adjusted. A full cycle time is decided by a channel having a weakest signal. In order to surely produce a full scale output from the weakest signal, a sufficient number of shift pulses is applied. When all number of the shift pulses for each cycle is once decided, the exposure time of the remaining channel is decided as part of an exposure time required for the weakest signal. Each column has an individual transfer gate control input. Then the timing of the transfer gate pule is decided and desirably, the exposure time is centered and deviation in color positioning is reduced.

Abstract: PURPOSE:To achieve the flatness of film and to prevent the occurrence of frictional force by constituting a camera in such a way that a means regulating the position in the optical axis direction of a film abuts on the film face at the time of photographing and retreats to a position away from the film face at the time of feeding the film. CONSTITUTION:After the film 13 is fed, an aperture frame 64 is brought into press-contact with a stopper 71 with the energizing force of a spring 70. Consequently, the film 13 is brought into press-contact by an aperture face 64a to show flatness. Simultaneously, since the film 13 is position-regulated by the stopper 71, the position on which a photographing lens focuses can be found precisely. The aperture frame 64 regulating the position in the optical axis direction of the film 13 is retreated from the film face during feeding the film, whereby the occurrence of frictional force can be prevented.
