Disclosed is an image data processing apparatus including a brightness detection part, a moving average calculation part, a change quantity detection part, a false correction determination part, and a correction part. The brightness detection part detects brightness of pixels in a prescribed range of each frame from image data acquired from an imaging device. The moving average calculation part calculates a moving average of prescribed cycles of the brightness to calculate a temporal average brightness value. The change quantity detection part detects a change quantity of an inclination of a waveform constituted of the temporal average brightness value. The false correction determination part determines a likelihood of false correction to the image data based on information representing a change of the inclination. The correction part corrects the image data acquired from the imaging device based on the determination result of the false correction determination part.
