摘要： In the image processors and the image processing methods of the present invention, the number of bits for quantizing image data is adjusted on the basis of a dynamic range of each block. Therefore, the error introduced by encoding is reduced without increasing the data amount of the encoded image data, and the response speed of a liquid crystal can be controlled appropriately by preventing unnecessary voltages from being applied due to the error introduced by encoding.

摘要： An image processor is provided with the high-frequency component detecting unit that calculates a convolution for each of regions of interest in part of an image region of input image data, to output the high-frequency component detection result for each pixel of interest; the smoothing unit that smoothes the image data, to output the smoothed image data; and the image data processing unit that combines based on the high-frequency component detection result the image data with the smoothed image data, to output the combined image data; wherein the image data processing unit varies the combination rate for the smoothed image data, based on the high-frequency component detection result. Thereby, even when a region in the image data contains such high frequency components as a checkered pattern has, an image resistant to moiré that would be generated in magnifying or reducing of the image on a region basis can be displayed without deterioration of image quality.

摘要： The frame-parallax-adjustment-amount generating unit outputs, as first parallax data, parallax data of an image portion protruded most among image portions protruded more than a first reference value from a pair of frame images forming a three-dimensional image. The pixel-parallax-adjustment-amount generating unit outputs, as second parallax data, parallax data of an image portion retracted more than a second reference value from the pair of frame images. The adjusted-image generating unit generates a pair of image output data by moving the entire pair of image input data to the inner side based on the first parallax data and moving an image portion retracted more than the second reference value of the pair of image input data based on the second parallax data to adjust a parallax amount and outputs the pair of image output data.
