A temporary correction-coefficient calculator of a moving-image correction-coefficient calculating apparatus calculates temporary gamma values to be applied to frames extracted from frames of a moving-image at a predetermined time interval, a storage unit stores the calculated temporary gamma values, and a correction-coefficient calculator calculates gamma values to be applied to the frames of the moving-image based on the stored temporary gamma values.

摘要:
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.

An image correction apparatus includes a gradient detection unit, a blur width detection unit, a correction area identification unit, and a correction unit. The gradient detection unit detects a gradient of a pixel value of each of pixels of an input image. The blur width detection unit detects a blur width at a position of each of the pixels of the input image. The correction area identification unit identifies a correction area based on the gradient detected by the gradient detection unit and the blur width detected by the blur width detection unit. The correction unit corrects a pixel value of a pixel in the correction area identified by the correction area identification unit.
