Abstract
A device for receiving a television image and for processing it in real time for display on a different type of screen. The incident television image is digitized and then a micro-zone, selected from a series of predefined micro-zones stored in a screen memory, is assigned to each pixel in the incident image. The image is written into the memory, micro-zone by micro-zone, and then read for display on the screen. Each micro-zone is selected to represent the incident pixel in a way appropriate to the format conversion and/or transformation to be applied to the image.
Claims12
A device to display television images on a screen, each television image being referred to as an analog incident image and an image displayed on the screen as a reconstituted image according to a reconstitution format, the analog incident image being formed by analog incident points, the device comprising:
- means for receiving said analog incident image and outputting progressively a digital incident image as digital incident points;
- address control means for identifying addresses of said analog incident points and converting said addresses into the reconstitution format;
- means for receiving said outputted digital incident image and generating a micro-matrix containing a plurality of elementary points, for each of the digitized incident points as it is received, the micro-matrix being selected from a series of micro-matrices whose size, form and content are defined according to the reconstitution format, wherein each of the micro-matrix selected by said digitized incident points of said incident image form the reconstituted image.
A device to display television images on a screen, each television image being referred to as an analog incident image and an image displayed on the screen as a reconstituted image according to a reconstitution format, the analog incident image being formed by analog incident points, the device comprising:
- means for receiving said analog incident image and outputting progressively a digital incident image as digital incident points;
- address control means for identifying addresses of said analog incident points and converting said addresses into the reconstitution format wherein said address control means includes a means for identifying addresses of the analog incident points and a transcoding means which allocates each analog incident point to a respective row number and point number in the reconstituted format with said transcoding means including a means for outputting a position error signal resulting from a difference between a format of the reconstituted image and a format of said incident image;
- means for receiving said outputted digital incident image and generating a micro-matrix containing a plurality of elementary points, for each of the digitized incident points as it is received, the micro-matrix being selected from a series of micro-matrices whose size, form and content are defined according to the reconstitution format.
