摘要:
A notebook information processor includes a lid including an image photographing unit and a display, and a main body, 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, a projective transformation parameter calculating unit that calculates the projective transformation parameter from a coordinate of the rectangle, 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, obtains a still image from the live view after the projective transformation, and stores the still image in the storage unit.
