Abstract

There is provided an image processing device including a first flicker component calculation unit that calculates a flicker component of a first exposure image which is a photographed image of a first exposure time, a second flicker component calculation unit that calculates a flicker component of a second exposure image which is a photographed image of a second exposure time different from the first exposure time, a first exposure image flicker correction unit that performs flicker correction on the first exposure image by applying the flicker component of the first exposure image calculated by the first flicker component calculation unit and generates a flicker-corrected first exposure image, and a second exposure image flicker correction unit that performs flicker correction on the second exposure image by applying the flicker component of the second exposure image calculated by the second flicker component calculation unit and generates a flicker-corrected second exposure image.

Description

technical field [0001] The present disclosure relates to an image processing device, an image processing method, and a program, and more particularly, to an image processing device, an image processing method, and a program that correct flicker occurring in an image. Background technique [0002] When a camera including an XY address scanning type image sensor such as a complementary metal oxide semiconductor (CMOS) image sensor captures an image under illumination of a fluorescent lamp, stripe brightness irregularities or color irregularities appear in video images. This phenomenon is called flicker. Flicker is caused due to the operating principle of the image sensor because a fluorescent lamp connected to a commercial power supply (AC) basically flickers repeatedly at double cycles of the power frequency. [0003] In an image in which flicker occurs, a luminance change pattern having a stripe shape extending in the horizontal direction appears. For example, when viewing...
