Abstract:
1. An image output apparatus including a first storage unit and a second storage unit that has a slower data access speed than the first storage unit, the image output apparatus comprising: an input unit inputs image data into the first storage unit after the image data has undergone rendering processing by an image processing unit; a control unit sets a first threshold of a remaining amount of the first storage and second threshold; a detection unit to detect the remaining amount of the first storage unit into which the image data input by the input unit is stored; a first determination unit determines whether the remaining amount of the first storage unit detected by the detection unit is smaller than the first threshold set by the control unit; a control unit to search for a page ID of the image data having a minimum data size, a processing order determination unit determines whether the page ID of the image data searched for has a data size smaller or larger than a second threshold, from among a plurality of image data stored in ascending order of the data size in the first storage unit; a control unit to, when the first determination unit determines that the remaining amount detected by the detection unit is smaller than the first threshold, transfer the image data found out by the control unit having a data size larger than the second threshold from the first storage unit to the second storage unit, and an output unit to output image data from the first storage unit or the second storage unit.
