Document Type and Number:

WIPO Patent Application WO/2007/094066

Kind Code:

A1

Abstract:

A flicker correcting apparatus and a flicker correcting method wherein the flicker occurrence frequency during a flicker detection can be reduced. A nonvolatile memory (5) stores information related to the power supply frequency of an illumination under an image pickup environment. A control part (6) performs, based on the information stored in the nonvolatile memory (5), a setting related to the flicker correction of an image pickup part (2). A signal processing circuit (23) detects flickers from an image data acquired in the set condition. The control part (6) writes, based on a flicker detection result of the signal processing circuit (23), the information, which is related to the power supply frequency of the illumination under the image pickup environment, into the nonvolatile memory (5).
