Patent Images

1. Apparatus for remote observation of objects comprising:

  • first means adjacent the objects for periodically generating data representative of an image of said objects, said data being broken into segments, each of which represents an element of said image;

    second means adjacent said objects for transmitting to said point of observation the most significant portion of the data segment associated with each image element;

    third means adjacent said point of observation for receiving said most significant portions and for displaying an image based on said most significant portions;

    fourth means adjacent said point of observation for transmitting to the location of said objects a first signal indicative of the acceptabilty of the image displayed by said third means;

    fifth means adjacent said objects for receiving said first signal and for transmitting to said point of observation the next most significant portion of the data segment associated with each image element only if said first signal indicates that the image displayed by said third means is not acceptable; and

    sixth means adjacent said point of observation for receiving said next most significant portions and for displaying an image based on said most and next most significant portions of said next most significant portions are transmitted;

    wherein said objects move relative to said first means so that a portion of an object feature to be observed may be in one image and another portion of said object feature may be in the next sequential image, and wherein said apparatus further comprises;

    first and second buffer means adjacent said point of observation, each of said buffer means being large enough to hold all of th data for one image;

    means for storing the data received from said second and fifth means for successive images in alternate ones of said first and second buffers so that the data for two sequential images is respectively stored in said first and second buffers; and

    means for displaying an image based on part of the data stored in said first buffer and part of the data stored in said second buffer so that both portions of said object feature are visible in the displayed image.
