Abstract
The invention relates to a document image processing apparatus in which a document image is lighted by a lighting device and is photographed and the photographed document image is displayed on a display, wherein the apparatus has a memory comprising a volatile memory device or/and a non-volatile memory device and a controller having control means which includes an operational device therein and can intermittently light on/off the lighting device, thereby enabling the document image to be stored and reproduced. The display is constructed by a non-thermion device such as liquid crystal or the like and the controller has means to intermittently light on/off a light source of the lighting device, so that an electric power consumption can be reduced and a portability is improved.
Claims18
An image processing apparatus, comprising:
- camera means for photographing a document image;
- display means for displaying the document image photographed by said camera means;
- moving means for moving said camera means and the document image relatively to each other so as to cause said display means to display a desired area of the document image;
- selection means for selecting a desired area of the document image displayed by said display means in accordance with the relative movement of said camera means and the document image by said moving means;
- memory means for storing the desired area of the document image selected by said selection means and at least one other area of the document image located at the periphery of the desired area of the document image, with the at least one other area of the document image being photographed by said camera means in accordance with the relative movement of said camera means and the document image by said moving means, wherein said memory means stores the selected area of the document image and only one other area of the document image located at the periphery of the desired area of the document image when a predetermined photographing magnification is selected;
- and
- control means for controlling said display means to display the document image stored in said memory means.
