    • 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.

    • An original is inclined with respect to an optical axis of a camera until the camera is positioned outside a reflected-image taking range by inclining a mounting surface of an original glass on which the original is placed. This makes it possible, when the original is taken by the camera, to prevent the camera from being reflected on the original and being taken in with the original. An imaging case formed of a diffusing member that is made of a high light-diffusing material or a high light-absorbing material is arranged in the reflected-image taking range. This makes it possible to prevent an object positioned in the reflected-image taking range from being reflected on the original and being taken by the camera. Consequently, clear image information can be more reliably obtained.
    • 原稿相对于照相机的光轴倾斜,直到相机通过倾斜放置原稿的原稿玻璃的安装表面而位于反射图像拍摄范围之外。 这使得当照相机拍摄原件时,可以防止相机在原稿上被反射并被原稿带入。 在反射影像取景范围内配置有由高光散射材料或高光吸收材料制成的扩散元件形成的成像盒。 这使得可以防止位于反射图像拍摄范围内的物体在原稿上被反射并被照相机拍摄。 因此,可以更可靠地获得清晰的图像信息。
