A code reading device includes an acquisition section, a derivation section and a correction section. The acquisition section reads a two-dimensional code image and acquires image information representing the two-dimensional code image. The derivation section derives an image characteristic quantity representing a ratio between a number of white pixels and a number of black pixels for a pre-specified region of the image information acquired by the acquisition section. The correction section, on the basis of a result of comparison of the image characteristic quantity derived by the derivation section with a reference value corresponding to the pre-specified region, applies correction to the image information to bring the image characteristic quantity closer to the reference value.

A two-dimensional-code detection system includes a reading unit, a recognizing unit, a calculating unit and a position specifying unit. The reading unit reads an image including plural two-dimensional codes. The recognizing unit recognizes position detection patterns of the respective two-dimensional codes from the read image, which includes the plural two-dimensional codes. The calculating unit that selects at least two of the position detection patterns of the two-dimensional codes. The calculating unit calculates a minimum unit forming each of the selected position detection patterns. The position specifying unit judges whether or not the minimum units forming the selected at least two position detection patterns are substantially equal to each other. When judging that the minimum units forming the selected at least two position detection patterns are substantially equal to each other, the position specifying unit specifies a position of a two-dimensional code using the selected at least two position detection patterns.

Block representative values are set adaptively based on the feature amount concerning the distribution state of a prepared histogram of input image data. Thus, if block truncation coding is executed based on an input image having mixed CG image and scanned image areas, efficient coding can be performed and a high-quality decomposed image can be provided. Further, when the histogram is divided into image data groups, the image data groups can be again divided to provide a high-quality decomposed image, thus efficient coding can be performed and a high-quality decomposed image can be provided more reliably.

An image process apparatus, for use with image data combining areas of different image characteristics such as text and photos, which achieves a predetermined target compression rate and simultaneously minimizes quality deterioration after decompression, is described. The image analysis circuit analyzes the composition of the entire image data and calculates the optimum compression parameter. The compression process is performed using a selected compression method for each predetermined block. At the time of compression, the value of the parameter is used in order to select an appropriate compression method by switching compression methods among a plurality of compression methods for each block unit. Using optimum compression minimizes the amount of memory required to store the information.
