Abstract:
1. A portable information terminal comprising: a display part which has a screen capable of displaying at least an image; an in-focus value computing part which computes an in-focus value from an original image, divides the original image into a plurality of equal areas, and computes an in-focus value for each of the areas equally divided; an image cutting part which cuts a thumbnail image from the original image based on the in-focus value computed at the in-focus value computing part, compares the in-focus value for each of the areas computed at the in-focus value computing part with a predetermined threshold based on an in-focus value distribution, detects an-areas having an in-focus value exceeding the predetermined threshold as plural in-focus areas, and cuts an image in a predetermined size including the plural in-focus area out of the original image to set it as a thumbnail image of the original image; a data storage part which stores data of the thumbnail image cut at the image cutting part; and a control part which reads the data of the thumbnail image stored in the data storage part as necessary and displays it on a screen of the display part.
