Abstract:
The film feed control apparatus performs frame feed operation in which a photographic film is fed in a specific direction when a given photographic frame of the photographic film is being set at a specific position, and the photographic film is stopped when a next photographic frame is set at the specific position. The film feed control apparatus is provided with a feed device that feeds the film, and a control device that controls the feed device in such a manner that, when an unfinished film, which includes exposed frames and unexposed frames, is loaded, stops the film if an unexposed frame is set at the specific position while the unfinished film is being fed in the specific direction, which is the same as the direction of film feed during the frame feed operation.
Abstract:
A camera has an exposure device for effecting a photographing operation on a film in response to manipulation of a member, and a self-timer for causing the exposure device to effect the photographing operation after the counting of a predetermined time. The self-timer has a first state for causing the exposure device to effect the photographing operation only once and a second state for causing the exposure device to effect the photographing operation plural times. The camera comprises a first display for indicating that the self-timer is in an operable state, a second display for indicating that the exposure device functions plural times in response to the manipulation of the number, independently of the self-timer, and a control device for controlling the first and second display. The control device is adapted to only activate the first display in the first state of the self-timer and to activate both the first and second displays in the second state of the self-timer.
Abstract:
A film feeding cessation adjusting device for cameras is capable of accurately stopping to a predetermined stopping position each frame of a film having a minimum number of perforations in order to ensure a sufficient data recording area. The film feeding cessation adjusting device includes a film feeding device for feeding a film, a perforation detection device for detecting a perforation of the film, a timer device for measuring a time required for film feeding, a stopping signal generating device for obtaining a time which is delayed by a predetermined period from the time at which the perforation detection device detects the perforation, on the basis of the results of the measurement of the timer device, and for generating a feeding stopping signal at the obtained time, and a control device for stopping film feeding of the film feeding device when it receives the feeding stopping signal.
Abstract:
An information recording device of a camera permits recording of more photographic information with an appropriate recording density without monitoring the film feeding speed constantly. The information recording device includes a recording assembly that records photographic information on a film recording area of film during film feeding. A feeding speed control assembly reduces the film feeding speed at a first time if the recording of photographic information is complete by the first time after the start of the recording assembly. The feeding speed control assembly reduces the film feeding speed at a second time after the first time if recording of the photographic information is not complete after reaching the first time. The feeding speed control assembly controls the feeding assembly to stop film feeding at a third time after reducing the film feeding speed. A recording control assembly allows information recording by the recording assembly during film feeding time until the film feeding speed is reduced.
Abstract:
A film feed control device of a camera in a prewind method in which unexposed film is pulled out from a loaded film cartridge and rewound into the film cartridge for each photography comprises a frame number memory for storing an exposable frame number of said film, a frame counter for counting a feed frame number by detecting the perforations of said film, a pulled-out film length detector for detecting that said exposable frame number of frames are pulled out from said film cartridge, based on said feed frame number counted by said frame counter and said exposable frame number stored in said frame number memory, and a film feed control for controlling the film feed so as to pull out said film by a predetermined amount even after the pull-out of the exposable frame number is detected, and then to oppose the first frame to be set at a predetermined position of said film to an aperture by reversing the film feed direction, when unexposed film is pulled out prior to photographing.
Abstract:
A light source color information recording apparatus comprising a recording control device that records light source color information related to the color of the light illuminating the photographic subject detected by a light source color information detection device in a specific information recording medium for each photographic frame, and a prohibiting device that prohibits recording of light source color information that would otherwise be performed by the recording control device, for photographic frames on which flash photographing has been performed.
Abstract:
A camera has a recording apparatus for magnetically recording finished photograph information, indicating exposure of a film frame, and for magnetically recording other photograph information for each film frame. The finished photograph information is recorded at a designated film area, while a film feed motor is in a transient speed state. Other photograph information is recorded in a designated film area when the film feed motor speed is constant. Appropriate positioning of the designated recording areas for recording information therein is determined by counting film perforations or by measuring a period of time during film feed subsequent to an exposure.
Abstract:
An information recording control apparatus in a camera is provided with reproducing means for reproducing information pre-recorded on film, recording means for recording information on the film, evaluation means for evaluating a state in which a signal is recorded on the film on the basis of the output state of the reproduction signal by the reproducing means, and control means for setting the recording condition of the recording means in conformity with the result of the evaluation by the evaluation means. The evaluation means evaluates the reproduction signal when the reproducing means reproduces the information pre-recorded on the film, and the control means sets the recording condition of the recording means in conformity with the result of the evaluation.
Abstract:
The camera of the present invention includes means for recording and reproducing information regarding the photographed frames of film, means for applying onto the cartridge of a film unit discriminative information indicative of whether the reading-out of the information regarding photographed frames is necessary, means for detecting the discriminative information, and means for controlling whether the reading out of the information regarding photographed frames should be effected in conformity with the result of the detection. Thus, when the camera is loaded with a film unit which does not require the reading-out of the information regarding photographed frames, like a new film unit which has never been loaded into a camera, the operation of reading out the information regarding photographed frames is saved.
