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.

摘要： A pattern presence/absence evaluation value generation unit (41) determines the presence or absence of a pattern by comparing sensing data (d3) and correction data (d44). Operating according to a pattern presence/absence evaluation value (d41) obtained from the pattern presence/absence evaluation value generation unit (41), a correction data updating unit (42) outputs correction data (d42) updated by weighted addition of the sensing data (d3) and the correction data (d44), increasing the weighting of the correction data (d44) when an image pattern is present and increasing the weighting of the sensing data (d3) when the image pattern is absent. A correction data subtraction unit (43) subtracts the correction data (d42) from the sensing data (d3) and outputs output sensing data (d4). It consequently becomes possible to reduce the effect of sensing signal level variations of the sensing signal generated within the interval of reading of the object being sensed, and read the pattern accurately.

摘要： A maximum value Yimax and a minimum value Yimin of input pixel data Ri, Gi, Bi for each pixel are determined. A saturation adjustment value X is determined using a function g(Yimax, Yimin), white pixel data Wo is determined using a function f(Yimin), and these are used to determine output pixel data Ro, Go, Bo. Even the saturation represented by RGB three-color data is high, conversion to RGBW four-color data with improved brightness can be made, without changing the hue.

摘要： An image processing device includes an edge-enhancing image enlarger that converts an input image to a high-resolution image with edge enhancement. A difference calculator determines differences between the high-resolution image and the input image. A high-resolution image corrector corrects the high-resolution image by diffusing the differences to pixels of the high-resolution image, thereby generating a corrected image in which edges are enhanced without image degradation in textured areas.

摘要： Image processors are provided for respective groups formed by grouping of images, the order of which is sequential when images respectively having overlapping portions corresponding to the same portion of an object are arranged so as to be adjacent to each other, and concurrently perform processing to detect combining-position information for combining an image in a group and an image adjacent to the image without any positional displacement by image-matching. The combining-position information between images belonging to different groups is respectively transferred, via combination-information transferring paths, between the image processors and between the image processors.
