Abstract
An image processing apparatus has editing modes in which an arbitrary image portion in an arbitrary area of a document image is extracted and outputted as a processed image, which editing modes include at least a trimming mode and a masking mode. The image processing apparatus has an input terminal for receiving an image signal describing a document image including a marking which designates a desired image portion to be trimmed or masked by at least encircling an area of the document image, a first circuit coupled to the input terminal for generating a first signal indicating a marked area which is encircled by the marking and excludes the marking, a second circuit coupled to the input terminal for generating a second signal indicating a marked area which is encircled by the marking and includes the marking, and a selector part coupled to the input terminal for selectively outputting one of a binary image signal derived from the image signal and a predetermined reference signal responsive to the first and second signals in the editing mode, thereby outputting a binary processed image signal describing a processed image in which the desired image portion is trimmed or masked at the…
