Abstract:
An image correction apparatus includes a smoothing unit, a blurred area detection unit, a correction amount calculation unit, and a correction unit. The smoothing unit smoothes an input image. The blurred area detection unit detects, for each pixel of a smoothed image obtained by the smoothing unit, whether or not each of the pixels is included in a blurred area. The correction amount calculation unit calculates an amount of a correction for a pixel that belongs to the blurred area based on the smoothed image. The correction unit corrects the input image by using the amount of a correction calculated by the correction amount calculation unit.
