    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 processing apparatus enhances contrast without producing color balance distortion or color collapse by generating a gradation-scale correction table from a distribution of a characteristic quantity of an input image signal, using the gradation-scale correction table to derive a gradation correction parameter for each pixel from a maximum component value of the pixel, and multiplying all components of the pixel by the gradation correction parameter.

    摘要： A luminance information detector (3) detects a maximum luminance-signal gradation information value and a minimum luminance-signal gradation information value from one frame of a luminance signal obtained from an image signal (Db) and outputs the values as luminance information values (Yi). A color information detector (20) detects a maximum color-signal gradation information value of the three color signals (RGB) obtained from the image signal (Db) for one frame and a minimum color-signal gradation information value of the three color signals (RGB) obtained from the image signal (Db) for one frame and outputs the values as color information values (Ci). A correction controller (45) calculates parameters (Pa) based on the luminance information value (Yi) and the color information values (Ci); a gradation corrector (5) processes negative color signals point-symmetrically with respect to the origin, according to the parameters (Pa), in the same way as it processes positive color signals. A display unit displays an image based on the image signal (Dc), which is the image signal (Db) after gradation-scale correction. Contrast can thereby be improved without excessive color collapse.
