Abstract
An image processing apparatus includes a first detection unit for detecting an edge of an input image on the basis of an input image signal, a second detection unit for detecting a screen portion of the input image on the basis of the input image signal, a processing unit for executing processing of the input image signal according to detection results of the first and second detection units, and a setting unit for setting detection modes of the first and second detection units.
Claims18
An image processing apparatus comprising:
- a) input means for inputting an image signal;
- b) detection means for detecting a feature of an input image on the basis of the image signal;
- and
- c) setting means for setting a detection mode of said detection means,
- wherein the detection mode includes at least a first detection mode for detecting an edge portion surrounded by a screen portion and a second detection mode for detecting an edge portion surrounded by a halftone portion, and
- wherein said setting means guides the setting of the first detection mode and the second detection mode.
