Patent ID: 7907171

Claim:
A notebook information processor, comprising: a lid including an image photographing unit and a display; and a main body including a storage unit and a control unit, wherein the control unit includes: a live view displaying unit that displays a live view obtained by photographing at least a portion of the main body within a photographing area of the image photographing unit on the display; a rectangle detecting unit that detects a rectangle for calculating a projective transformation parameter from the live view displayed on the display by the live view displaying unit; a projective transformation parameter calculating unit that calculates the projective transformation parameter from a coordinate of the rectangle detected by the rectangle detecting unit; and a still image obtaining unit that performs a projective transformation on the live view so as to obtain a live view photographed from a front direction, using the projective transformation parameter calculated by the projective transformation parameter calculating unit, obtains a still image from the live view after the projective transformation, and stores the still image in the storage unit.
