ABSTRACT:
A video data acquisition system has a video camera for taking pictures of articles and from the picture image digitizes and selects signals within a predetermined amplitude range as representations of pixels of the picture image. A combination of horizontal, vertical and diagonal pixel collection circuitry acquires, in real time, the pixel counts necessary to establish the identity and orientation of the article represented by the image.
