Patent ID: 8269875

Claim:
A portable information terminal comprising: a display part which has a screen for displaying images; an in-focus value computing part which computes in-focus values from an original image that has been previously captured by dividing the original image into a plurality of divided areas and computing an in-focus value for each of the plurality of divided areas; an image cutting part which cuts a thumbnail image from the original image based on the in-focus values computed by the in-focus value computing part, by comparing the in-focus value for each of the plurality of divided areas with a predetermined threshold based on an in-focus value distribution, detecting an area having an in-focus value exceeding the predetermined threshold as an in-focus area, and cutting an image in a predetermined size including the in-focus area out of the original image to set it as the thumbnail 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 for display on the screen.
