    摘要: 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.

    摘要: 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.

    摘要: 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. The second control block issues a second write pulse cliffs differing from the first write pulse with timing independent of the first control block. The processing block includes the register, a write pulse generating circuit which generates the first write pulse according to the write request signal from the first control block, and a switching circuit which selects either the first write pulse or the second write pulse and inputs the selected pulse to the register.

    摘要: An image processing apparatus includes a distortion correction unit, a distortion correction range calculation unit, a control unit, a storage control unit, and a margin storage memory. The distortion correction unit performs a distortion correction processing on image data stored in a frame memory. The distortion correction range calculation unit calculates distortion correction ranges. The control unit determines an input image range from present distortion correction range and next distortion correction range. The storage control unit calculates a range for a part of the image data corresponding to the input image range from the present distortion correction range and the next distortion correction range. The margin storage memory stores the image data of the range calculated by the storage control unit. The image data input to the distortion correction unit includes both the image data from the frame memory and the image data from the margin storage memory.
