  • Abstract
    A computer peripheral for the input of grey scale image data is described. Four versatile modes of operation provide flexibility in the collection of data sequentially or at random. A standard t.v. camera with an interlaced raster is used as the image transducer. The composite video signal produced by the camera provides all the information necessary for the peripheral interface circuitry. The peripheral described in the paper enables the collection of four bits of intensity on a 256 × 256 square grid.
