Abstract
In a picture-information processing apparatus, information of an edge in a picture is generated from information of luminances in the picture. Data of a mask corresponding to the edge is generated from the information of the edge. Information of feature points on an equal-luminance line in the picture is generated from the information of the luminances in the picture. The equal-luminance line is composed of segments extending between the feature points. A decision is made as to whether or not each of the segments of the equal-luminance line agrees with an edge line segment in response to the data of the mask and the information of the feature points. An edge decision signal is generated which represents the result of the decision. The edge decision signal is added to the information of the feature points.
