摘要： An image signal representing image information containing a periodic pattern is processed before it is broken up into halftone dots. First, the image information is averaged to generate an unsharpness signal, and then the unsharpness signal is processed for edge sharpness to generate a sharpness signal. Thereafter, a halftone-dot image is generated from the sharpness signal. More specifically, the sharpness signal Sij* is generated from a first unsharpness signal Uij which is produced by averaging the image information and a second unsharpness signal Uij which is produced by averaging the first unsharpness signal Uij, according to the equation:Sij*=Uij+K.multidot.(Uij-Uij)wherei=1, 2, . . . n,j=1,2, . . . n, andK: sharpness parameter.The halftone-dot image thus reproduced is sharp and free of a moire pattern which would otherwise result from the periodic pattern.

摘要： An image reception system is disclosed, which includes a tuner for selecting one of broadcast channels of CATV, a video detector connected to the tuner for deriving output signals having video signals and command data of the selected channel, a data fetch circuit for extracting the command data and character data out of the output signals derived from the video detector, a display controller for controling video outputs to be displayed on a display screen, and a key pad for supplying the control command to the display controller. In this case, the display controller includes a character generator for generating character signals to be displayed on the display and masking circuit for superimposing masking signals on the video signal on request.
