1. A method of performing color correction on a frame image of moving image data, comprising: using a processor to perform the steps of: detecting a transition region in a target frame image of the color correction; setting an update region in the target frame image, where low frequency data is to be updated, in accordance with the detected transition region; generating the low frequency data of the update region from image data of the target frame image; and generating low frequency data of the target frame image in accordance with low frequency data of a reference frame image different from the target frame image and with the generated low frequency data of the update region, and performing the color correction on the target frame image using the generated low frequency data of the target frame image.
