<P>PROBLEM TO BE SOLVED: To provide an information processing apparatus, an indication system, and a control program which improve deterioration of viewability produced by difference of intensities of an object and others when an image is projected on a region including the object from a projection apparatus, and the region is photographed by an imaging apparatus. <P>SOLUTION: A control unit 101 recognizes the object from plural images captured by a video camera 5, and extracts an outline shape of the object (step S21, 22). The control unit 101 calculates average illuminance of the inside of the object outline and average luminance of the outside of the object, and determines whether a calculated difference between the average luminance of the outline inside and the average illuminance of the outline outside is equal to or more than a predetermined value (step S23, 24). Finally, the control unit 101 increases gradation of a part corresponding to the outline inside of the object in an image projected by a projector 4 (step S25) when the difference of the average illuminance of the outline inside and the average illuminance of the outline outside is less than a predetermined value. <P>COPYRIGHT: (C)2009,JPO&INPIT |
