Abstract: A liquid crystal display unit has a transmissive liquid crystal plate having a number of pixels arranged on a two-dimensional basis, on which an image is formed, and a light source unit emitting beams of light of a plurality of luminescent colors for irradiating said liquid crystal plate from back. An interface circuit receives an image signal representative of a color image to sequentially form on said liquid crystal plate a plurality of separation images in which the color image is separated in association with the plurality of luminescent colors of said light source unit. The interface circuit causes said light source unit to flash with a luminescent color associated with a separation image formed on said liquid crystal plate in synchronism with a sequential formation of the separation images onto said liquid crystal plate. Beams of light emanated from the light source unit and transmitted through the liquid crystal plate reproduce an image.

Abstract: A magnetic recording and regenerating unit for photographic film and a camera, which feed photographic film coated with a magnetic recording layer, records magnetic information in the magnetic recording layer, and regenerates magnetic information from the magnetic recording layer. In the magnetic recording and regenerating unit for a camera, the number of turns of a coil wound around a core included in a magnetic head is small. Thus, one magnetic head is able to record and regenerate magnetic information. The number of turns of the coil is determined so as to output a regenerated waveform which does not enable reading of the magnetic information but permits determination of whether any magnetic information is recorded or not. Whether any magnetic information is recorded or not is determined based on the output voltage from a smoothing circuit, a peak hold circuit, etc. which receive signals output from the magnetic head via an amplifier.

Abstract: A camera or a remote controller with memory stores pieces of title information which correspond to predefined titles. The title information includes a title number and title display data. The title number indicates a predefined title to be printed together with a frame image on photographic film. The title display data is displayed on a LCD in the same mode as a printing mode. The pieces of title information are sequentially fetched from the memory in response to a title selection operation. The title display data of a fetched piece of title information is displayed on the LCD so that a desired title can be selected.

Abstract: A photographic camera having a halfway film rewind mode in which a cartridge having film with part of the frames exposed and part of the frames unexposed is rewound into the film cartridge. The camera also allows the user to set a mode in which data relating to the cartridge can be entered into the memory of the camera. The memory of the camera stores the user input cartridge data together with data representative of the member of unexposed film frames remaining on the film in the cartridge.

Abstract: A camera detects at least two magnetic tracks accompanying film frames which do not have information recorded thereon. The camera transports the film to place the foremost film frame accompanied with the unrecorded magnetic tracks to a specific position in the camera to avoid double exposure of an exposed film frame accompanied with an unrecorded magnetic track.

Abstract: A camera has a feeding motor by use of which photo film is fed. 24 groups of perforations are arranged along one edge of the photo film, and regularly at a distance L2 one group from another. Each of the perforation groups is associated with one frame, and includes two perforations arranged at a distance L1 therebetween. To control the photo film feeding, pulses are generated in synchronism with the photo film feeding. The perforations are detected through a sensor. The pulses are counted while the photo film is fed by the distance L1 or L2, and during a period started upon movement of a first one of the perforations past the sensor and finished upon detection of a second one of the perforations at the sensor. A counted number of the pulses is compared with a reference value upon finish of counting the pulses. If the counted number is equal to or more than the reference value, the feeding motor is decelerated.
