INVESTIGATION AND DEVELOPMENT OF METHODS FOR INCREASE OF IMAGE QUALITY IN BROADCAST TELEVISION RECEIVERS BY MEANS OF TRANSFER TO PROGRESSIVE SCANNING IN THEM

The analysis of the method promoting to the increase of the image quality in the broadcast television systems with transfer in the receivers to the progressive scanning at reception of the standard signal for 625 lines with staggered scanning has been given. The method on the theoretical determination of the screen brightness flicker visibility depending on the critical image frequency and relative observation distance confirmed with the made experiments has been proposed. The model for visible system of the observer has been developed and proposed. The adaptive method for transfer in the television receiver to the progressive scanning permitting to increase the sharpness of the TV image over vertical and to decrease the flickers of the lines at transmission of the movable and imovable objects that will secure the increase of the TV image reproduction quality has been proposed. The materials can be used at development of the new television systems for a purpose of increasing image quality and in the educational process on the departments of the higher educational institutionsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
