The disclosure provides a system that can easily calculate a similarity rate of a target document when comparing the target document. An array set of a designated type of words (e.g., nouns) is respectively extracted from a test document and a reference document as an arrayed test document and an arrayed reference document. A word included in a common word set of the arrayed test document and the arrayed reference document is defined as true as a proposition, and other words are defined as false as propositions. Further, when a ratio of words defined as true as propositions in a word array of a first designated length including a word among words defined as false as propositions is greater than or equal to a first designated value, the word is redefined as a wildcard and true as a proposition.

The present invention provides a technique for encoding Bayer array RAW image data that responds to whether priority is placed on encoding efficiency or on image quality. To that end, a first plane transforming unit transforms the RAW image data into R, G0, G1, and B planes. A second plane transforming unit transforms the RAW image data into a luminance plane and three color difference planes, each constituted of a different color difference component. It is then determined whether to encode using the first plane transforming unit or the second plane transforming unit, and the planes are then encoded according to the determination.

To suppress image degradation of a tile boundary while suppressing an increase of an amount of encoded data due to tile division. When performing a wavelet transform on a tile of interest, a wavelet transform unit performs a wavelet transform by referring to pixel data of the tile of interest and a neighboring tile that neighbors the tile of interest to obtain transformation coefficient data of a set resolution level. From transformation coefficient data obtained from the neighboring tile, the wavelet transform unit supplies a subsequent quantizing unit with transformation coefficient data of each resolution level that is closest to a boundary between the tile of interest and the neighboring tile, as well as all transformation coefficient data obtained from the tile of interest.
