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: A camera includes a photographic information output circuit section, a CPU, a PPM signal conversion circuit section, a drive section for a plurality of magnetic heads, and a film feeding section. The CPU converts several parallel data items which are output from the photographic information output circuit section into a single serial data item and outputs it to the PPM signal conversion circuit section, which then converts this single serial data item thus output from the CPU into several PPM signals, and then the PPM signal conversion circuit section supplies the PPM signals to the magnetic head drive section.

Abstract: A camera is provided in which when a film unit exposed up to a midroll frame in one wind mode is reloaded, the exposure of the film unit can be continued in another wind mode without causing double exposure. The camera discriminates whether the next frame adjacent to an exposed frame which has just been exposed is an unexposed frame or an exposed frame. If the next frame is an exposed frame, the operation of rewinding film into a cartridge is performed to thereby render further photographing impossible. Thereby, when a film unit exposed up to a midroll frame in one wind mode (e.g. the ordinary wind mode) is loaded into the camera, the continuation of the exposure of the film unit can be effected in the other wind mode (e.g. the prewind mode) without causing double exposure.

Abstract: In a camera comprising a CPU, a film feeding section, a serial data clock creating circuit section, a PPM conversion circuit section, a photographic information output circuit section, and a magnetic head drive section, the CPU produces a reference clock CLK depending on a film winding speed in the film feeding section, and the serial data clock creating circuit section creates a serial data clock SCK corresponding to the reference clock CLK. The CPU converts photographic information from the photographic information output circuit section into serial data and outputs the serial data in synchronization with the serial data clock SCK. Based on the serial data and the reference clock CLK both from the CPU, the PPM conversion circuit section converts photographic information into a PPM signal and outputs the PPM signal to the magnetic head drive section for magnetically recording it on a film.

Abstract: This invention relates to cameras operable to select one film supply system from either a normal wind-up system or a preparatory wind-up system. The camera has a selector switch for selecting one of the film supply systems, and an inhibiting means for inhibiting that the two systems are applied to one film by the switch, a write means for recording selected information onto a film or a storage device provided in the cartridge, and a read means for reading the selected information and the frame information written in the device. The switch selects a film supply system which is indicated by the selected information read out from the device of the loaded film by the read means. Additionally, a film supply means is provided for preparing and supplying the film in accordance with the frame information read out by the read means. The film supply means can wind up the film to supply even when either of the two film supply systems is set.

Abstract: A camera according to the present invention comprises: an indicator driving device which drives an indicator of a film cartridge so that the indicator indicates either a film-usable status or a film-unusable status; a film-feeding device; a discriminating function for discriminating whether the sensitivity of the loaded film is equal to that set for exposure calculation so as to output a matching signal when the former sensitivity is equal to the latter and to output a mismatching signal when the former differs from the latter; an instructing function for giving an instruction to rewind a partially-used film; and a control function for, at least on condition that the instruction is given, rewinding the film by the film-feeding device. The control function also controls the indicator driving device so that the indicator indicates the film-usable status when the matching signal is output and so that the indicator indicates the film-unusable status when the mismatching signal is output.

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.

Abstract: A camera provides information to a printer to produce a print in which an image of a photographed object is of a desired size. More particularly, the enlargement magnification of a printer is controlled in accordance with information recorded on a recording medium in a camera. Determination of the enlargement magnification involves various parameters including, for example, a specified desired magnification (requested magnification) and photographing magnification, which may be determined by calculation from object distance and focal length of the photographing lens. Modification data may be produced to accommodate changes in photographing angle that accompany focusing of the photographing lens. Focal length or object distance may be varied as required to provide a print image size as close as possible to that desired (and within limitations of the camera).

Abstract: Photographing information is stored for each exposed frame of film in a camera, and the stored information is read out and magnetically recorded at each frame during feeding of the film in a predetermined direction. If a film feeding failure occurs while information is being recorded, a film feed failure signal is generated, which causes the film to be fed in the opposite direction and then to be fed in the predetermined direction again for recording of information read out from storage.

Abstract: A camera is so structured that trimming photographing in which the F-number of the photographing optical system does not change is preferentially selected for the zoom-up photographing of a dark object field, so that the shutter time does not extend unnecessarily and the risk of hand-vibrated photographing is reduced.
