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 marked area.
What is claimed is 1. An image processing apparatus having editing modes in which an arbitrary image portion in an arbitrary area of a document image is extracted and outputted as a processed image, said editing modes including at least a trimming mode and a masking mode, said image processing apparatus comprising:input terminal means for receiving an image signal describing a document image, said 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; first means coupled to said input terminal means for generating a first signal indicating a marked area which is encircled by said marking and excludes said marking; second means coupled to said input terminal means for generating a second signal indicating a marked area which is encircled by said marking and includes said marking; and selector means coupled to said input terminal means for selectively outputting one of a binary image signal derived from the image signal and a predetermined reference signal responsive to said first and second signals in the editing mode, thereby outputting a binary processed image signal describing a processed image in which said desired image portion is trimmed or masked at the marked area. 2. An image processing apparatus as claimed in claim 1 in which said selector means outputs a binary processed image signal describing a processed image in which said desired image portion is trimmed or masked at the marked area excluding said marking in the trimming and masking modes.
BACKGROUND OF THE INVENTION The present invention generally relates to image processing apparatuses, and more particularly to an image processing apparatus in which an area of a document is designated by a marking entered in the document and a portion encircled by the marking is treated as a marked area which is the subject of a trimming or a masking process.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a system block diagram showing a general construction of an image forming apparatus which may be applied with an image processing apparatus according to the present invention;
DETAILED DESCRIPTION FIG. 1 shows a general construction of an image forming apparatus which may be applied with an image processing apparatus according to the present invention. The image forming apparatus has an image scanner 1, an image processing part 2 and an image output part 3. The image scanner 1 optically scans and reads an image of a document and supplies an image signal of the document image to the image processing part 2. The image processing part 2 subjects the image signal to a predetermined image processing and outputs an image signal which describes a processed image. The processed image is outputted from the image output part 3. The image output part 3 may be constituted by an image forming means which forms an image on a paper or the like by electrophotography or displays the image on a display means. For convenience sake, it is assumed hereunder that the image forming apparatus is a copying machine and the image output part 3 forms the image by electrophotography.
