    摘要： A digital image recording and/or reproducing apparatus using a plurality of compression methods may include, in a recording section, (a) data compression circuitry, including a plurality of compression circuits which have different compression methods, for changing a compression rate for input digital image data by changing a combination of the plurality of compression circuits compressing the digital input image data and (b) circuitry for recording (1) the digital image data compressed by the data compressing circuit and (2) data representing the compression rate of the digital image data compressed by the data compressing circuit. The apparatus may include a reproducing section having (a) a reproducing circuit for reproducing from the recording medium the digital image data compressed with the compression rate provided by the combination of different compression methods, (b) detecting circuitry for detecting the data representing the predetermined compression rate stored on the recording medium, and (c) reconstruction circuitry for reconstructing the digital image data reproduced by the reproducing circuitry according to the representing data detected by the detecting circuitry.

    摘要： A camera having an image capture unit and first and second image compression units adapted to compress a digital image outputted from the image capture unit in a first compression method and a second compression method which is different from the first compression method. First and second image decompressions units are adapted to decompress a digital image compressed in the first and second compression methods. The camera is adapted to provide a digital image outputted from the image capture unit to the first or the second image compression unit. The camera is further adapted to store a digital image compressed in the first or the second image compression unit in a removable memory unit, to provide a digital image read from the removable memory unit to the first image decompression unit if the digital image read from the removable memory unit is compressed in the first compression method, and to provide a digital image read from the removable memory unit to the second image decompression unit if the digital image read from the removable memory unit is compressed in the second compression method.

    摘要： In a case in which image data used to form an image on a recording medium in a plurality of scans performed across a recording area of the recording medium is generated, a coefficient determination unit determines assignments of output density for the scans on the basis of density characteristics corresponding to the type of recording medium indicated by a recording-medium signal. Multipliers and binary conversion units generate image data for the scans from input image data on the basis of the assignments of the output density.
