Abstract
PURPOSE:To read a film having the abnormal density by using the reference value to discriminates the density of a base part from that of a code part of the film and replacing the reference value before the next block after the 1-block data is read. CONSTITUTION:The bar code data is fetched by an arithmetic processing part 17 from a bar code detector 2 synchronously with a step motor 8. Then this bar code data is ternalized and stored as the block data after the parity check. At the part 17 the block data stored in response to the film bar codes should be equal to each other as long as the same film is used. Then the approximately equal data can be obtained from a normal film through the ternalizing process and the reference replacement process. When the bar codes are read and the block data is stored by an amount equal to a single piece of film, a histogram of the block data is produced. Then the block data having the largest number is retrieved and decided as the bar code data of the film.
