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.

The present invention relates to a signal processing apparatus and a method, a recording medium, and a program, in which portions except an edge can be smoothed while the edge whose change in pixel value is steep is held correctly. A pixel of attention is determined in step S11, and a neighboring pixel is determined in step S12. In step S13, a difference in pixel values between the pixel of attention and each neighboring pixel is calculated. In step S14, according to a relationship in size between the difference and a threshold value ε., flags are raised for the neighboring pixel and a neighboring pixel which are symmetrical. Furthermore, a flag is also raised for a neighboring pixel away from, in view of the pixel of attention, the symmetrical neighboring pixel for which the flag is raised. In step S15, 7-pixel taps centered around the pixel of attention are averaged by weight. However, with respect to the neighboring pixel for which the flag is raised, the pixel value is replaced by that of the pixel of attention C, and is calculated. The present invention can be applied to a video camera, a television receiver, etc.

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.
