IMAGE PROCESSING DEVICE, METHOD, AND PROGRAM, AND IMAGE DISPLAY DEVICE

摘要

An image processing device includes: a terminal that receives an image signal for a display for displaying images in directions, the display including pixels having sub-pixels and a parallax optical element for directing light from each sub-pixel in a direction predetermined for each sub-pixel, the signal including a grayscale value of each sub-pixel; a memory that stores information indicating a defective sub-pixel displayed in a direction due to a defect of the parallax optical element; and a corrector that determines, using the grayscale value of a sub-pixel whose predetermined direction is another direction different from the predetermined direction of the defective sub-pixel, a grayscale value of the defective sub-pixel for the image displayed in the other direction, and outputs a corrected image signal including, as a grayscale value of the defective sub-pixel, the smaller of the grayscale value of the defective sub-pixel in the image signal and the determined value.

主权项

1. An image processing device comprising:
an image input terminal that receives an image signal for a display for displaying a plurality of different images in a plurality of different respective display directions, the display including a plurality of pixels and a parallax optical element, the plurality of pixels each including two or more sub-pixels corresponding to two or more respective colors, the parallax optical element directing light from each of the sub-pixels in a display direction predetermined for each sub-pixel among the plurality of display directions, the sub-pixels displayed in the respective display directions being mixed together in the display, the image signal including a grayscale value corresponding to each of the sub-pixels of the display; a defect information memory that stores defect information indicating a defective sub-pixel, the defective sub-pixel being one of the sub-pixels that is displayed in one or more display directions (hereinafter referred to as the defect display directions) of the plurality of display directions in addition to the predetermined display direction of the sub-pixel due to a defect of the parallax optical element; and a corrector that determines, as a correction value, on a basis of the grayscale value of at least one sub-pixel whose predetermined display direction is another display direction different from the predetermined display direction of the defective sub-pixel indicated by the defect information in the image signal, a grayscale value corresponding to the defective sub-pixel for the image displayed in said another display direction, and outputs a corrected image signal including, as a grayscale value of the defective sub-pixel, the smaller of the grayscale value of the defective sub-pixel included in the image signal and the correction value.
