摘要： A setting circuit sets a quantization value per input image on the basis of a noise value of the whole input image, and a quantization circuit performs quantization on first image data to generate second image data. Quantization value based on the noise value the whole input image can realize appropriate denoising depending on the noise level of the whole input image.

摘要： A data storage controlling device has: a compression unit which performs lossless compression on each compression object region; determination means which determines whether or not the lossless compression is possible in each compression determination region including a plurality of compression object regions; and a storage control unit which performs storage control in each compression determination region in such a manner that data after the lossless compression in a compression determination region is stored as compressed data into a storage unit when it is determined that the lossless compression in each compression object region included in the certain compression determination region is possible, and image data before the lossless compression in the certain compression determination region is stored into the storage unit when it is determined that the lossless compression in each compression object region included in the certain compression determination region is impossible.

摘要： A first edge strength calculation circuit calculates an edge strength of each pixel in the image on the basis of results of detection by the first edge detection circuit. A filter strength setting unit sets a filter strength of a two-dimensional lowpass filter for each pixel, on the basis of the edge strength calculated by the edge strength calculation circuit. A second edge strength calculation circuit calculates an edge strength of each pixel in the image, on the basis of results of detection by the second edge detection circuit. An enhancement strength setting circuit sets an edge enhancement strength of the edge enhancement filter for each pixel, on the basis of the edge strength calculate by the second edge strength calculation circuit.
