Abstract
A local tone mapping circuit includes an average value calculation unit suitable for calculating an average value of an absolute value of a difference between a center pixel data and a neighboring pixel data of the center pixel data; a range calculation unit suitable for calculating a range between a maximum value and a minimum value of the absolute value of a difference between the center pixel data and the neighboring pixel data; and a local tone mapping strength adjusting unit suitable for differently allocating a weighted value according to a distance between a center pixel and an edge pixel among neighboring pixels of the center pixel based on the range between the maximum value and the minimum value calculated by the range calculation unit and the average value calculated by the average value calculation unit, and adjusting a local tone mapping strength according to an allocated weighted value.
