Patent ID: 8704768

Claim:
An image processing apparatus, comprising: an operation picture producing portion which produces an operation picture containing indicia corresponding to a plurality of image processing functions among which a selection is made by an external operation; an image display unit which displays said operation picture; an output unit which outputs said operation picture to an external display device; a position input portion including a touch responsive unit having a portion placed over a screen of said image display unit, with which an operator can designate a position on the operation picture displayed on the external display device by touch operation; an image adding portion which adds a cursor indicating the position entered through said position input portion to the operation picture; an identifying portion which identifies a selected image processing function, among said plurality of image processing functions, based on the designated position input by said position input portion; an image processing portion which carries out the selected image processing function; and a determining portion which determines whether the external display device is connected to said output unit, wherein, when said determining portion determines that the external display device is not connected to said output unit, said position input portion operates in a first operating mode to enter a position designated by the touch operation as an absolute position on the operation picture displayed on said image display unit, the position of the external operation being the same as the position on the operation picture displayed on said image display unit, and when said determining portion determines that the external display device is connected to said output unit, the operation picture with the cursor is output to the external display device through said output unit, said image display unit does not display said operation picture, and the position input portion operates in a second operating mode to enter the position designated by the touch operation as a relative position, wherein, in the second operating mode, the position input portion measures displacement of the position designated by the touch operation per unit time, and adds a vector indicative of the measured displacement to a previous cursor position to determine a next cursor position.
