Claim One:
1. An information processing apparatus which is connected to a projection device projecting an annotation image input from an external terminal onto a projection area, and an image capture device capturing the projection area, comprising: a recognizing portion that recognizes an object from a plurality of images captured by the image capture device; an outline deciding portion that decides an outline of the object recognized by the recognizing portion; a calculating portion that calculates average luminances of an area inside and an area outside of the outline of the object decided by the outline deciding portion; a determining portion that determines a difference between the average luminance of the area inside of the outline calculated by the calculating portion and the average luminance of the area outside of the outline calculated by the calculating portion, and determines whether the determined difference is equal to or greater than a predetermined value; a projection image adjusting portion that, when the determining portion determines that the determined difference is equal to or greater than the threshold value, generates an adjustment image comprising an inside area corresponding to the area inside of the outline of the object and an outside area corresponding to the area outside of the outline, and the projection image adjusting portion sets a luminance of either the inside area of the adjustment image or the outside area of the adjustment image; a projection image inputting portion that inputs the adjustment image generated by the projection image adjusting portion to the projection device, and causes the projection device to project the adjustment image onto the object; and a capture controlling portion that causes the image capture device to capture the object in a state where the adjustment image is projected onto the object by the projection device, wherein the projection image adjusting portion sets the luminance of either the inside area of the adjustment image or the outside area of the adjustment image such that, when the adjustment image is projected onto the object, a gradation of the luminance of whichever one of the inside area and the outside area of the outline of the object has the lower average luminance is increased.
