ABSTRACT:
Apparatus and Method for providing images on a photosensitive media is disclosed. The invention provides for the multi-point exposure correction of recorded grey scale hardcopy images which utilizes line by line attenuation of video data in a unique pattern. Also exposure compensation is provided for by decreasing the amplitude of the video signal, on a line by line basis, from a predetermined nominal value which is in the recording cathode ray tube's dynamic range. The invention thus performs its function without compromising the dynamic range of the recording mechanism.
