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:

Method of and apparatus for smoothing an image having a periodic pattern

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.

Image reception system

A developer's activity control system and a photographic processing apparatus controlling same that divides the activity of the developing solution into a plurality of stages on the basis of the results of the processing of control strips and takes the necessary action for each stage, said developer control system includes a means for storing the initial conditions of the developing system and a means for comparing these initial conditions with the present conditions, the output of said comparing means being used to properly select the necessary action for each stage.
