摘要： An object of the present invention is to provide an image decompression apparatus, a medium recording an image decompression program, and an image decompression method capable of sequentially decompressing compressed data of a plurality of images.
An image decompression apparatus includes: a request frame number acquisition section that sequentially acquires request frame numbers which are the numbers assigned to frames for which decompression is required in the forward or backward direction of the frame number; a compressed data acquisition section that acquires compressed data of a first compression unit to which the request frame number belongs and compressed data of a second compression unit adjacent to the first compression unit in the backward direction of the frame number; a decompression section that decompresses the compressed data of the first and second compression units acquired by the compressed data acquisition section to obtain decompressed images; and an image holding section that holds the decompressed images of the first and second compression units generated by the decompression section and extracts decompressed image corresponding to the request frame numbers so as to output the decompressed images.

摘要： An image reader (2300) for optically reading an image on a medium by means of manual operations comprises: a housing having an image reading unit coming in contact with the medium when reading an image; a medium detecting unit (105) provided on an image reading surface of said housing for detecting the medium; a control processing unit (2301) for controlling the medium detecting unit (105) so that detection of the medium can normally be performed according to environments and conditions for reading an image, and for processing a result of detection by said image detecting unit; and an image reading unit (107) for reading image information of the medium according to the result of detection processed by said control processing unit (2301). The medium can be detected even in an environment or under conditions in which an external disturbance would otherwise prevent detection of the medium.
