摘要： The present invention relates to a display apparatus, a marker signal making process, a marker signal detector circuit, and a control signal generator circuit that are suitable for use when making a display in which a display screen is divided into a plurality of areas and images whose picture qualities are different at every area are displayed. Thus, in the present invention, image signals (R/G/B) from input terminals 1R, 1G, 1B are supplied to a preamplifier IC 3, e.g. to respective sharpness improving circuits 32R, 32G, 32B therein. Image signals derived from the preamplifier IC 3 are subjected to DC voltage conversion by a cutoff adjusting amplifier 6 and then supplied, e.g. to a cathode ray tube 7 as a display means. A microcomputer 40 which is present within this apparatus and controls various kinds of functions forms first and second DC voltage data for controlling, e.g. the sharpness. These data are made into analog control DC voltage by D/A converters 34A, 34B and then selected by a switching circuit 36 to be supplied to the preamplifier IC 3. This switching circuit 36 is controlled by an arbitrary control signal. This enables the picture quality of image of photograph, moving video, etc. to be improved without making the information on characters, numerics, etc. hard to see, when displaying the image of photograph, moving video, etc. together with the information on characters, numerics etc.

摘要： A aperture compensation circuit which provides improvement in picture quality when a multi-media image is displayed and an RGB monitor employing the same includes a sharpness circuit provided between input terminals and a preamplifier. A lowest value detection circuit of the sharpness circuit detects a lowest value signal from among R, G and B signals supplied from the input terminals, and a differentiation circuit differentiates the lowest value signal to produce a differentiation signal. A slice circuit slices a component of the differentiation signal which corresponds to a portion at which a change from black to white occurs with an arbitrary amplitude to produce a second differentiation signal. The second differentiation signal from the slice circuit and the R, G and B signals supplied from the input terminals are added by addition circuits to effect contour correction of the R, B and G signals. A CRT is driven by the R, G and B signals for which contour correction has been performed.
