摘要： An image processing apparatus and an image processing method are disclosed for generating coded data having a desired data size at a high speed. The image processing apparatus includes a coding part, two memories, a setting part and a data size adjustment part. The coding part partitions a wavelet coefficient of image data into bit-planes and generates coded data of the image data through entropy coding on the wavelet coefficient for each of the bit-planes. The data size adjustment part adjusts a size of the coded data such that the size falls within an acceptable range including the target size set by the setting part by sequentially discarding a portion of the coded data in a least significant order based on the size of the coded data portion corresponding to each of the bit-planes.

摘要： A group of pass transistors causes x.sub.i, x.sub.i-- B to pass therethrough when 1X indicates affirmation but not pass therethrough when 1X indicates negation, and causes x.sub.i-1, x.sub.i-1-- B to pass therethrough when 2X indicates affirmation but not pass therethrough when 2X indicates negation. In a switch-transistor arrangement portion, when each of 1X and 2X has a value indicating negation, a first electric potential appears at a first node, and a second electric potential appears at a second node. A positive-and-negative-responding pass-transistor group causes the value of the first node to pass therethrough when COMP has a value indicating negation, and causes the value of the second node to pass therethrough when COMP has a value indicating affirmation.

摘要： An image processing apparatus includes a wavelet transform unit that performs compression encoding in a hierarchical manner by performing discrete wavelet transform on pixel values for each of one or more rectangular regions dividing image data. A digital watermark obtaining unit obtains digital watermark data to be embedded into wavelet coefficients generated by the wavelet transform unit. A characteristics extracting unit extracts characteristics of the wavelet coefficients for each of the rectangular regions. An embedding specification determination unit determines an embedding specification of the digital watermark data with respect to the wavelet coefficients in accordance with the characteristics of the wavelet coefficients for each of the rectangular regions that are extracted by the characteristics extracting unit. A digital watermark embedding unit embeds into the wavelet coefficients the digital watermark data for each of the rectangular regions in accordance with the embedding specification of each of the rectangular regions.
