Title: Device, system and method for picture processing, and storage medium
Inventor: TAKIGUCHI HIDEO
IPC: G06T11/60
Filed: 1999-12-27
Abstract: PROBLEM TO BE SOLVED: To provide a picture processor enabling a user to easily and reliably recognize even a horizontally long or vertically long picture by using its thumbnail display. SOLUTION: On preparing a reduced picture (thumbnail picture) from a plurality of pictures by using a picture management and list display software 201, the aspect ratio of an object picture is checked. When it is judged that the aspect ratio is larger than prescribed and that the picture is sufficiently long horizontally or vertically, the thumbnail picture is prepared not by simply reducing the whole object picture but a thumbnail picture of only the center part except for the end parts of the object picture is prepared by fixing the aspect ratio to a prescribed value.
