摘要： Influences of physiological stereoscopic elements are removed by image processing using projection transformation. A horopter-plane image projection unit 311 is designed to project a non-stereo image supplied via a signal line 129 onto a cylindrical plane (horopter plane) including a horopter circle. The size of the horopter circle is specified using, for example, the radius as horopter circle information. Additionally, the relationship with two eyes is specified by the interocular distance. A display surface right-eye projection unit 316 is designed to project an image projected on the horopter plane onto a display surface for the right eye. A display surface left-eye projection unit 317 is designed to project the image projected on the horopter plane onto a display surface for the left eye. Therefore, retinal images that are identical to each other are supplied to the two eyes to remove influences of physiological stereoscopic elements, and stereoscopic depth is given.

摘要： The invention provides an image processing apparatus and an image processing method. An area to which image data belongs is discriminated, and a correction coefficient to be used for correction of a pixel value of the image data is produced based on a result of the discrimination. Then, the pixel value of the image data is corrected with the correction coefficient. The relationship in magnitude among pixel values in the same area is maintained because the same coefficient is used, but pixel values which belong to different areas can be varied or even reversed. This allows the gradation of an entire image to be corrected while preventing partial deterioration of the contrast.

摘要： The present invention relates to an image processor and an image processing method for compensating gradation by effectively avoiding drop of partial contrast through application to an image processor such as television receiver, video tape recorder, television camera and printer or the like. A domain to which an input image data belongs is judged, for example, with reference to the low frequency element r (i, j) of the pixel value x (i, j) and the signal level x (i, j) of the image data forming an input image VT is compensated on the basis of the result of judgment r(i, j).

摘要： Each of a plurality of input images is smoothed. A plurality of smoothed images different from each other in the degree of smoothing thus results. Each of first and second synthesizers calculate an edge intensity based on an intermediate synthesized image generated from at least one smoothed image and having a relatively large degree of smoothing and another smoothed image having a relatively small degree of smoothing, and synthesizes the intermediate synthesized image and the smoothed image based on the edge intensity, thereby generating a synthesized smoothed image. A second synthesized smoothed image generated by the second synthesizer is output as a final synthesized smoothed image representing an illumination component, and is then used as a coefficient for converting a pixel value.

摘要： A histogram section determines as a motion vector at a pixel of interest the candidate motion vector with highest frequency from among a candidate motion vector at the pixel of interest and candidate motion vectors at pixels neighboring the pixel of interest supplied by a template matching section, and supplies it to a motion-vector correcting section. The motion-vector correction section evaluates the confidence level of the motion vector supplied by the histogram section based on the luminance gradient around the pixel of interest detected by a luminance-gradient detecting section and a control signal indicating whether correction should be carried out supplied by the template matching section. If it is determined that the confidence level of the motion vector is low, the motion vector is corrected.
