Patent ID: 8106963

Claim:
A flicker correcting device, comprising: a nonvolatile memory that stores information on a power source frequency of illumination under an image pickup environment previously encountered during a previous image pickup; a flicker correction setting unit that performs, upon starting, an initial setting related to flicker correction of an image pickup unit that picks up an image, based on the information on the power source frequency of illumination under the image pickup environment previously encountered that is stored in the nonvolatile memory; a flicker detecting unit that detects a flicker in image data acquired in an initial state set by the flicker correction setting unit; and a writing unit that writes information on a power source frequency of illumination under an image pickup environment currently encountered into the nonvolatile memory based on a result of detection by the flicker detecting unit, for use in a subsequent initial setting upon starting by the flicker correction setting unit, wherein, before the flicker detecting unit detects the flicker in the image data, the flicker correcting device generates the image data by performing flicker correction, according to the initial setting, on the image, and then the flicker detecting unit performs flicker detection on the image data generated by performing the flicker correction on the image.
