Patent ID: 8063976

Claim:
An image pick-up apparatus for shooting an object, comprising: a recording unit for recording data; a filter having a transmitting wavelength band for transmitting a light from the object, having the transmitting wavelength band; a spectral control unit for inputting a drive signal to the filter to change the transmitting wavelength band of the filter in plural steps; a single image pick-up unit disposed at a rear side of the filter, for generating image data every time when the transmitting wavelength band of the filter is changed by the spectral control unit; and a record control unit for recording in the recording unit plural pieces of image data generated by the single image pick-up unit; wherein the spectral control unit comprises: a drive history recording unit for recording a drive history when the transmitting wavelength band of the filter is changed in plural steps; and a correction unit for correcting a current driving amount and a current driving direction based on a last driving amount and a last driving direction stored in the drive history recording unit, wherein the transmitting wavelength band of the filter is changed in plural steps based on the driving amount and driving direction corrected by the correction unit when the drive signal is input to the filter.
