An information processing apparatus and method is disclosed wherein slideshow images can be reproduced for an arbitrary period of time. A scaling coefficient calculation section divides a slideshow reproduction time period by a selected effect total time period to calculate the ratio between them as a scaling coefficient and supplies the calculated scaling coefficient to a correction section. The correction section corrects the reproduction time period of each effect of a deletion result supplied from a deletion candidate deletion section or each selected effect supplied from an effect selection section using the scaling coefficient supplied from the scaling coefficient calculation section so as to make the total reproduction time period of the selected effects coincide with a slideshow reproduction time period. The invention can be applied to a personal computer or the like which can handle still pictures.
