Abstract
An apparatus for carrying out, at frame rates, entity detection and verification on bit-mapped raster graphic systems by providing an entity identification bit sequence with each feature of the picture displayed. The apparatus includes a display coupled to a store for input data, serially sending items of data to the display, together with means for identifying the items of data so supplied, such that all the items of data forming a selected feature, i.e., line, circle, background or etc. of the display can be identified, and stored. Comparison and register means are used to drive a modulating means to verify the display of the items of data, forming the selected feature, when a correlation occurs between the selected feature and the feature formed by the items of data sent from the store. Verification may be emphasizing, i.e., brightening, flashing, color change, etc. the feature selected.
