There is an imaging apparatus including a noise suppression circuit. The system operates to detect bits that have failed a programming verify operation and to reprogram these bits with an adjusted programming voltage so as to obtain the desired Vt while reducing stress on the bits and achieving a narrow Vt distribution. The actuators define the grating plane, and are positioned in response to the wavefronts from the gratings and a reference flat, thus producing the interferogram that contains the alignment information. The calculation unit produces a tracking error signal and a position information signal based on the light detection signals. Further, upon detecting discontinuation of the touch, a different operation in the game can be controlled with the thumbstick represented as being at a default height in response to a subsequent touch.
