    • A data-processing device includes a plurality of data generation units, a plurality of bit change number calculation units, a bit change number comparison unit, a first data selection unit, and a bit-coupling unit. The data generation unit arranges input data to generate first conversion data based on each prescribed arranging method. The bit change number calculation unit compares values of respective bits in the first conversion data output at the n-th time and the (n+1)-th time by the corresponding data generation unit, and calculates a bit number based on the comparison result as a bit change number. The bit change number comparison unit compares values of the respective bit change numbers, selects the data generation unit, and outputs selection information. The first data selection unit outputs any one first conversion data selected based on the selection information as selection data. Then, the bit-coupling unit couples the selection information.

    • An image processing apparatus includes image processors and a margin storing buffer. The image processors read an input image data from a frame memory for each image data of a plurality of block lines each having a first number of pixels along the columns and a second number of pixels along the rows. The margin storing buffer stores the image data of the margin portion used also in the image processing of the image data of the next block line, among the image data of the present block line input to each of the image processors. Each of the image processors performs the image processing on an image data including the image data of the present block line and the image data of the margin portion, at the time of image processing on the image data of the next block line.

    • An image processing apparatus includes a processing block, a first control block, and a second control block. The first control block issues a write request signal for inputting a first write pulse to a register of the processing block.
