摘要： A compact camera has a built-in light-emitting display device which displays, as print information, a specific code. The specific code includes alphabetical characters when a print information set switch is operated. The device is alternatively allowed to display a six digit number. The alphabetical characters or number represents date information pertaining to exposure of a film frame, including a year, a month and a date. The print information appears as a visible image on developed film and is optically read by a photographic printer so as to automatically set the photographic printer to a printing condition determined by the print information.

摘要： After one dimension of error detection and correction has been performed on a block of data, error correction in the other dimension may be selected to be either erasure-and-error correction or simply error correction. The selection is of erasure-and-error correction, which uses results of the error correction in the first dimension, when an indication of a burst error has been detected during the row error correction, or when the number of maximum error corrections within the row error correction is small enough, or when uncorrectable errors within the row error correction is small enough. Otherwise, error correction is selected.

摘要： An error correction circuit is capable of performing correction errors in data at a high speed. A syndrome generator (2) calculates syndromes of RS codes based on partial data streams which are given from a data buffer (1). A received CRC generator (13) performs CRC coding on the partial data streams which are given from a data buffer (1) to thereby obtain received CRCs. An error pattern CRC generator (14) calculates error pattern CRCs of the respective partial data stream based on error patterns which are generated by an error pattern generation circuit (33). Under the control of a control circuit (40), the operations performed by the syndrome generator (2), the received CRC generator (13) and the error pattern CRC generator (14) are carried out at the same time. An improvement in the speed of error correction of the partial data streams performed by the error correction means directly leads to an improvement in the speed of the whole error correction.

摘要： A distance measuring device of camera for measuring distance to a pictured object includes pulse-driven first, second and third beam projecting elements. When a distance to the pictured object is long and beams of the beam projecting elements reflected from the pictured object are small in quantity or become nil, the first beam projecting element is pulse-driven until the number of light emission reaches a predetermined first maximum number of light emission, and the second and third beam projecting elements are pulse-driven until the number of light emission reaches a predetermined second maximum number of light emission which is less than the predetermined first maximum number of light emission. Because of this, when a distance to the pictured object is long and the beam projecting elements are pulse-driven to the predetermined first or second maximum number of light emission, it is possible to shorten a distance measuring time.
