Abstract
An analog video signal obtained from a television camera having a 4:3 aspect ratio is converted into a square array of N.times.N square pixels corresponding to the pixel content in the center of the television camera by apparatus which includes an analog-to-digital converter having as its analog input the analog output signal of the television camera and providing a sampled digital data output, the converter having an encode input and a data-ready output in addition to its analog video input and digital data output; a synchronization recovery circuit coupled to the video input and adapted to extract from the composite signal a composite synchronization signal containing line synchronization information, frame synchronization information and field index information, and an interface circuit coupled to the encode input of the analog-to-digital converter and the data-ready output and receiving the data output of the converter for converting the 4:3 aspect ratio of the television camera into a square image corresponding to a square in the center of the screen containing a square array of N by N square pixels.
