    Abstract: An image capture system wherein brightness and contrast levels are set automatically. A video camera scans an image and generates an analog output signal indicative thereof which is utilised by the image capture system to create rows and columns of picture elements. The image is initially scanned utilising a trial brightness and contrast level and then analysed to determine the number of saturated picture elements within the scanned image. Thereafter, the brightness and contrast levels are adjusted so that the number of saturated picture elements tends towards a selected small number.

    Abstract: An image processing system for viewing a representation of an overscanned captured image (10) on a display that is incapable of displaying the full image as originally captured, the system consisting of means for digitising the image, means (30) for storing a first block of data from the digitising camera (14) representing the captured and digitised image, logic for generating a second data block from a first data block of the digitised image data by removing every Nth data element of the first data block, where N is less then the number of elements in the first data block, and a display (26) for displaying the second data block overlayed upon at least a portion of the digitised image.
