ABSTRACT:
An image input apparatus has a video camera which photographs an object placed on a stage of the apparatus and which outputs a video signal for reproducing an image of the object on a screen of an external device, such as a monitor. The operator can designate a selected part of the reproduced image by displaying an arrow mark on the image. Display position of the arrow mark is designated by operating cursor keys of a control panel of the image input apparatus while referring to the monitor. The display position is entered in the form of a pair of coordinate values of X-Y coordinates which are defined on the screen. In accordance with the coordinate values, data for displaying the arrow mark as a dot pattern is read from a memory in synchronism with the video signal and mixed with the video signal.
