ABSTRACT:
An automatic image quality controlling apparatus in an electronic copier classifies image data obtained through an image pickup means is divided into character part and picture part, detects an overall height of characters based on a distance between character lines in character part and detects an overall width of characters based on a distance between character columns in character part. Based on the information thus obtained, the apparatus decides an overall size of outline squares for characters, assumes positions of segments where characters should be located, comparatively judges whether any isolated image data resides in the assumed segments, separates irregular components based on the result determined and erases the irregular components separated.
