摘要： An image processing apparatus receives n-bit image data, carries out an α-bit bit extension, and outputs (n+α)-bit image data, where n and α are positive integers. The apparatus also performs an epsilon filtering operation that uses the additional gray levels provided by the bit extension to smooth out false edges caused by the bit extension without smoothing out real edges. The output image preserves both the smoothness of regions of gradual change and the sharpness of abrupt changes in the input image.

摘要： To interpolate a frame between the current frame and a first delayed frame preceding the current frame, an image processing device generates test interpolation data for the first delayed frame from data in point-symmetric positions in the current frame and in a second delayed frame preceding the first delayed frame. Motion vectors pointing from the first delayed frame to the current frame are found by evaluating different test interpolation data against the actual data of the first delayed frame. These motion vectors are converted to pairs of motion vectors pointing from the first delayed frame and the current frame to the interpolated frame, and these pairs of motion vectors are used to generate accurate data for the interpolated frame from the data of the first delayed frame and the current frame.

摘要： An image processing apparatus 100 includes a parallax calculating unit 1. The parallax calculating unit 1 receives input of a pair of image input data Da1 and Db1 forming a three-dimensional video, calculates parallax amounts of respective regions obtained by dividing the pair of image input data Da1 and Db1 into a plurality of regions, and outputs the parallax amounts as parallax data T1 of the respective regions. The parallax calculating unit 1 includes a correlation calculating unit 10, a high-correlation-region extracting unit 11, a denseness detecting unit 12, and a parallax selecting unit 13. The correlation calculating unit 10 outputs correlation data T10 and pre-selection parallax data T13 of the respective regions. The high-correlation-region extracting unit 11 determines a level of correlation among the correlation data T10 of the regions and outputs high-correlation region data T11. The denseness detecting unit 12 determines, based on the high-correlation region data T11, a level of denseness and outputs dense region data T12. The parallax selecting unit 13 outputs, based on the dense region data T12, the parallax data T1 obtained by correcting the pre-selection parallax data T13.

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.
