Patent ID: 7414639

Claim:
An image processing apparatus, comprising: a comparison part comparing an image information value which indicates predetermined image information of an original image, with a corresponding predetermined reference value which is previously set for each of the predetermined image information; and a sharing-ratio determining part which, based on a comparison result of said comparison part, determines a sharing ratio for sharing processing resources between a first processing way and a second processing way different from said first processing way, for changing a size of image data, wherein: said sharing-ratio determining part calculates the sharing ratio, and adjusts the sharing ratio in the processing between the first and second processing ways so that the entire process of a predetermined image size-change processing is completed within a given time duration, if a processing time for performing the entire processing of the predetermined image size-change processing utilizing the first processing way but not the second processing way exceeds the given time duration, the image processing apparatus includes a print function, and the adjustment of the sharing ratio is made in such a manner that the sharing ratio is gradually changed, a required time duration is calculated every time of the gradual changing of the sharing ratio, the thus-calculated required time duration is compared with the given time duration, and then, the sharing ratio at which the comparison result indicates that the required time duration corresponds to the given time duration is obtained.
