Abstract:
1. A camera for use in a sensed image projection system for projecting an image of a sensed projection target onto a screen, comprising: an image pickup lens; a sensing element; an image processing unit which: (i) discriminates a sheet portion of a document as the projection target from a whole image via the image pickup lens and the sensing element, (ii) extracts the discriminated projection target from the whole image, (iii) enlarges or reduces the image of the projection target by a magnification or reduction at which one of a vertical size and a horizontal size of the image of the projection target corresponds to a predetermined shape of an image projection frame of the screen, and (iv) adds a background color to a margin produced between the enlarged or reduced image of the projection target and the image projection frame of the screen, in such a way that the image of the projection target is entirely displayed within the predetermined shape; and an output unit which outputs an image subjected to image processing by the image processing unit as an image to be projected onto the screen.
