Claim:
1. An image processing apparatus, comprising: an image reducing unit configured to perform a reduction process with a reduction ratio in one of a primary scanning direction and a secondary scanning direction of an image for each reduction target area, and subsequently perform a reduction process with a reduction ratio in the other of the primary scanning direction and the secondary scanning direction of the image for each reduction target area said primary scanning direction and said secondary scanning direction being substantially in the vertical and horizontal direction respectively; a binarizing unit configured to binarize pixel values of the pixels included in the reduction target area in the reduction process; a characteristic value identifying unit configured to identify a characteristic value on the basis of a pattern of the binarized pixel values in the reduction target area by classifying the pattern based on at least three predetermined conditions with a different characteristic value for each predetermined condition, and integrate the characteristic value by summing up the characteristic values; and a control unit configured to terminate the reduction process of the image performed by the image reducing unit, change the reduction ratio so as to increase a size of a reduced image, and cause the image reducing unit to perform the reduction process with the changed reduction ratio again when the integrated value of the characteristic value exceeds a predetermined threshold value before the image reduction unit finishes the reduction processes in the primary scanning direction and the secondary scanning direction of the image.
