ABSTRACT:
A scanner for reading an original image by hand scanning usually detects scanning positions of the reading sensor on the original image sequentially and stores read image data into image memory according to said scanning positions. However, an area in which the image data is not stored may appear when free scanning is done such that its pixel density exceeds a permitted limit. This area, if it appears, degrades the quality of the image which is reproduced in the image memory. The scanner of the invention detects the area in which the image data has not been stored, and prevents the appearance of such an area in the resulting image. It also judges an abnormal state that is beyond the prevention capacity and informs the operator of such a state. Furthermore, when it detects a scanning error caused by sensor problems, it halts storing the image data and informs the operator of the scanning error.
