摘要： The frame-parallax-adjustment-amount generating unit outputs, as first parallax data, parallax data of an image portion protruded most among image portions protruded more than a first reference value from a pair of frame images forming a three-dimensional image. The pixel-parallax-adjustment-amount generating unit outputs, as second parallax data, parallax data of an image portion retracted more than a second reference value from the pair of frame images. The adjusted-image generating unit generates a pair of image output data by moving the entire pair of image input data to the inner side based on the first parallax data and moving an image portion retracted more than the second reference value of the pair of image input data based on the second parallax data to adjust a parallax amount and outputs the pair of image output data.

摘要： A block noise detector has a spatial difference calculator that calculates differences between values of adjacent pixels. A spatial difference comparator detects edges by comparing the calculated differences. Eight counters count edges detected at different groups of positions spaced eight pixels apart in each horizontal line. The maximum count and the group of positions at which it occurs are detected at the end of each horizontal line to detect block noise and the positions of the block boundaries. The block noise detector is small in size because it only has to count edges in one line at a time, and detects edges accurately by comparing the difference at a given position separately with differences to the left and differences to the right.

摘要： An image signal generating unit supplies a single image signal to multiple image display units having different unit numbers. Embedded in the image signal is an index signal designating the image display units on which the image signal is to be displayed. Each image display unit compares its unit number with the index signal to select displayable frames of the image signal, preferably storing and displaying the most recent selected frame. Each image display unit can thereby display a different image. The image signal may have a standard format.

摘要： A tone step detector detects whether the tone of n-bit input image data varies gradually, and generates a tone processing control signal indicating that a tone step is contained. A bit shifter bit-shifts the n-bit input image data to the left by α bits, to generate (n+α)-bit image data. A tone processor smoothes the image data of the (n+α)-bit image data generated by the bit shifter, in the region where the tone processing control signal indicates that a tone step is contained, to generate (n+α)-bit image data having been smoothed in the above-mentioned region. Because of the selective smoothing, degradation in the image quality due to quantization is reduced even when an analog image signal whose tone varies gradually is input.
