Zusammenfassung:	An image of a block 20a or the like entering a space above a play mat 18 is picked up by an image pickup apparatus 12, and an information processing apparatus 10 detects and recognizes the block on the basis of a picture of the block in a picked up image and performs information processing. The play mat 18 includes a play field 100 that defines a detection space for the block, and a calibration chart 102 including at least a plurality of regions of colors of different luminances. The image pickup apparatus 12 adjusts an exposure time period, a gain value for each color component and a correction rule upon gamma correction on the basis of the picture of the calibration chart 102 in the picked up image.
