Abstract:
An image processing apparatus comprising:detecting means for detecting a contour vector by scanning an input image in units of a region comprising 2Ã—2 pixels in a main scanning direction; judgment means for judging whether a connection relationship of a contour vector detected by said detecting means and the contour vector which has been already detected can be determined; registration means for registering, if judging can be determined by said judgment means, a data indicating a connection relationship of a contour vector detected by said detecting means and the contour vector which has been already detected to a registration table; and holding means for holding, if judging cannot be determined, a data indicating a vertical contour vector having undetermined vertical connection relationship in a holding table and a data indicating a horizontal contour vector having undetermined horizontal connection relationship in a support buffer, wherein a size of said holding table is a size capable of storing pixels corresponding to the number of pixels in the main scanning direction of the input image, and said size of said support buffer is a size capable of storing one data.
