Image processing apparatus, method and non-transitory computer readable medium capable of calculating time for displaying and printing thumbnail images

Abstract

An image processing apparatus includes a print controller, a calculation unit, a generation unit, and a display controller. The print controller makes print images for plural pages be printed. The calculation unit calculates, if a time required for display is longer than a time required for printing, a page interval at which display of a reduced image in synchronization with completion of printing of a print image is possible. The generation unit generates reduced images of print images for pages among the plural pages at the calculated page interval. The display controller makes a reduced image of a print image be displayed in synchronization with completion of printing of the print image. If a reduced image of a print image to be displayed in synchronization with completion of printing of the print image has not been generated, the display controller makes a reduced image generated last be displayed.
