Abstract
A picture extracting apparatus and method extract picture signals of a picture area bounded by a black frame from a film such as a microfilm or an ultramicrofilm where the black frame is applied in the upper, lower, left and right borders. More specifically, a CPU (9) determines the upper and lower black frame portions based on the number of 'black' picture signals for each scanning line of a film counted by a counter (4) and specifies the associated scanning lines. In response to the change in the picture signals from 'black' to 'white' and from 'white' to 'black' on the specified scanning lines, the left and right black frame portions are determined and the respective addresses of the rear and front edges of these picture signals are specified by a rear edge register (5) and a front edge register (6). A gate circuit (3) passes therethrough only the picture signals between the addresses of the specified scanning lines to extract the picture signals of the picture area bounded by the black frame.
