    摘要: An image signal processing method and apparatus for practicing the method are capable of identifying and differentiating information not having tonal rendition such as characters and linetone images from information having tonal rendition such as photographs and pictures, based on the difference of signal characteristics, for example based on the fact that the spatial frequency distribution in portions of an image not having tonal rendition are in the higher frequency range compared to that of the portions of the image having tonal rendition. The method and apparatus are also capable of conducting different processes on the identified different images.

    摘要: Data is compressed using content addressable memory without disruption despite error using a plurality of content addressable memories to detect sequentially repeating data elements of the data. Compression information is generated for each sequence of repeating data elements that repeat for at least a compression threshold without any one of the plurality of content addressable memories generating an indication of an error for a matching content addressable memory entry. Individual data elements are output for each of the data elements that do not repeat for the compression threshold. Compression information is generated for each sequence of repeating data elements that repeat for at least the compression threshold and then generating a currently searched data element that matches the repeating data elements when any one of the plurality of content addressable memories generates an indication of an error for a content addressable memory entry that matches the currently searched data element.

    摘要: Various embodiments are provided to reduce a processing time taken when plural bit lengths each assigned to plural strings are converted into plural codes. In one exemplary embodiment, in response to input of the plurality of bit lengths, a number of strings assigned each of the bit lengths, a bit length assigned to each of the strings, and a sequence number of each string in a group of strings assigned each of the bit lengths are recorded. A plurality of base codes are generated on the basis of the numbers of the strings recorded by the recording unit, the base codes each being a code used as a base for codes having the same one of the bit lengths. A plurality of codes is generated by performing in parallel a plurality of processes respectively for the plurality of strings.

    摘要: An image defect correction system using directional detection. An image data memory stores a two-dimensional image data output from an image capturing device. A decision means decides whether a target pix cell is a defective pix cell by deciding whether an image data of the target pix cell is a prominent spot using a plurality of image data of the target pix cell and 8 adjacent pix cells arranged in 4 directions of upper-lower, left-right, lower-right and upper-right, counting direction number having the prominent spot, and deciding whether the target pix cell is the defective pix cell according to the counted direction number. A replacement means replaces the image data of the target pix cell with a predetermined image data when the target pix cell is determined to be the defective pix cell.
