ABSTRACT:
The apparatus and method (10) are applied to an image sensor (26) having an image area (32) for receiving light to form a first predetermined number of lines of image data. In certain image sensors (40, 100), a storage area (44, 108) is coupled to the image area (42, 106) for receiving a second predetermined number of lines of image data from the image area (42, 106) in response to an image area gate signal. A serial register (68, 110, 126) is further coupled to the storage area (44, 108) for receiving successive lines of image data therefrom in response to a STORAGE AREA GATE signal, and the serial register (68, 110, 126) further serially outputs the successive lines of image data in response to a SERIAL REGISTER GATE signal. The image centering command input from an operator is generated by and received from a vertical and horizontal adjust input device (12, 14) that generates a vertical adjust value and a horizontal adjust value indicative of the amount of adjustment needed for centering the image. A timing controller (24) is further coupled to the image sensor (26) and the vertical and horizontal adjust input device (12, 14) to generate the IMAGE AREA GATE, STORAGE AREA GATE, SERIAL REGISTER GATE signals, a plurality of display timing signals, and also to determine the timing relationships between the signals in response to the vertical and horizontal adjust values.
