An information processing apparatus includes an acquisition unit acquiring output values of a plurality of pixels from an image sensor, the plurality of pixels having a predetermined pixel size, a projection control unit projecting a first pattern image and a second pattern image with a distance smaller than the predetermined pixel size, the first pattern image including one or more boundaries, the second pattern image including one or more corresponding boundaries corresponding to the one or more boundaries, a storage unit storing as, a reference value, an output value of one or more reference pixels, the output value picks up the first pattern image, and an adjusting unit adjusting the projection position by comparing an output value of the one or more reference pixels and the stored reference value, the output value of the one or more reference pixels picks up the second pattern image while moving the projection position.
