IMAGE PROCESSING SYSTEM AND COMPUTER-READABLE RECORDING MEDIUM

摘要

A technique to remove fog from an image more appropriately has been called for. An image processing system is provided, including: a haze depth estimating unit that derives a haze depth estimate value of one frame among a plurality of frames included in a moving image; a parameter adjusting unit that adjusts a parameter to be used in a haze removal process of the one frame based on a haze depth estimate value of the one frame, and a relationship between the one frame and a past frame of the one frame; and a haze removing unit that executes a haze removal process on the one frame based on the parameter adjusted by the parameter adjusting unit.

1. An image processing system comprising:
a haze depth estimating unit that derives a haze depth estimate value of one frame among a plurality of frames included in a moving image; a parameter adjusting unit that adjusts a parameter to be used in a haze removal process of the one frame based on a haze depth estimate value of the one frame, and a relationship between the one frame and a past frame of the one frame; and a haze removing unit that executes a haze removal process on the one frame based on the parameter adjusted by the parameter adjusting unit, wherein using a haze depth estimate value of the one frame as a haze depth target value of the one frame, the parameter adjusting unit adjusts a parameter to be used in a haze removal process of the one frame such that the parameter adjusted in the past frame becomes close to, stepwise, the haze depth target value.
