摘要： PROBLEM TO BE SOLVED: To correct displacement between both images generated when superimposing and displaying a left-eye image and a right-eye image arranged in a vertical direction and displayed on a display panel on a screen by a projection optical system. SOLUTION: A resolution conversion unit 204L for the left-eye image comprises a vertical conversion unit 204V and a horizontal conversion unit 204H. The vertical conversion unit 204V performs vertical resolution conversion processing to adjust the number of pixels in a vertical direction, and the horizontal conversion unit 204H performs horizontal resolution conversion processing to adjust the number of pixels in a horizontal direction. Also, the horizontal conversion unit 204H performs conversion processing to adjust a horizontal size. Also, the vertical conversion unit 204V performs conversion processing to correct a vertical bow-like distortion. Thus, since the conversion processing for horizontal size adjustment and the conversion processing for the correction of the vertical bow-like distortion are possible, it becomes possible to correct the displacement due to the difference of the horizontal size and the vertical bow-like distortion between the left-eye image and the right-eye image on the screen.

摘要： PROBLEM TO BE SOLVED: To correct deviation of a left-eye image and a right-eye image displayed on a display panel by image rotation that is generated when displaying both the images on a screen while overlapping them by a projection optical system. SOLUTION: A left-eye image resolution converting section 204L includes a vertical converter 204V and a horizontal converter 204H. Regarding resolution conversion, the vertical converter 204V performs vertical resolution conversion processing for adjusting the number of pixels in a vertical direction and the horizontal converter 204H performs horizontal resolution conversion processing for adjusting the number of pixels in a horizontal direction. Furthermore, regarding image rotation, the vertical converter 204V performs vertically oblique deformation processing and the horizontal converter 204H performs horizontally oblique deformation processing. By performing vertically oblique deformation processing and horizontally oblique deformation processing upon an image signal, an image on a liquid crystal panel can be rotated. A right-eye image resolution converting section is configured also similarly to the left-eye image resolution converting section. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PURPOSE:To prevent a friar on an image screen by a liquid crystal display element by detecting the second higher level among the levels of three primary colors signals and reducing the amplitude of a video signal when the detected peak value is large than a reference value. CONSTITUTION:The 2nd higher level among the levels of the three primary color signals R, G, B is detected by detecting means 4-7. The output of a max. value detecting circuit 7 is checked by a peak value detecting circuit 8 and the peak value thereof is detected. The detected peak value is compared with the reference value corresponding to the dynamic range of the liquid crystal display element by a comparator 11 and the amplitude of the video signal is reduced to the reference value or below when the peak value of this time is larger than the reference value. The generation of the friar on the image screen is thereby obviated even if the level of the video signal is large; in addition, the dynamic range of the liquid crystal display element is effectively utilized.
