A parameter obtaining circuit obtains a color saturation parameter which determines a degree of adjustment of color saturation of a captured image. A correction parameter calculation circuit calculates a color saturation level correction parameter which determines a degree of saturation level correction processing based on the color saturation parameter and a position of a pixel included in the captured image. A correction processing circuit performs the color saturation level correction processing on the captured image in accordance with the color saturation level correction parameter.

An apparatus provides a unit capable of improving gradation characteristics of a plurality of images (crop images) even in a case where a plurality of users individually performs cropping (cutting out) on a distributed image, calculates a target gradation range based on histograms of the regions cropped by the plurality of users, and executes gradation conversion based on an overlapping ratio of the plurality of target gradation ranges.

An image processing apparatus includes a noise level calculation circuit, an inter-frame change amount calculation circuit, a recursive coefficient calculation circuit, and a composite processing circuit. The noise level calculation circuit detects a noise level of a signal of a focused frame in moving images. The inter-frame change amount calculation circuit detects the amount of change between the focused frame and the previous frame by using the noise level of the focused frame, the signal of the focused frame, and a signal of the previous frame after a noise reduction process. The recursive coefficient calculation circuit sets a coefficient for use in the noise reduction process according to the amount of change. The composite processing circuit performs the noise reduction process on the signal of the focused frame by using the signal of the focused frame, the signal of the previous frame after the noise reduction process, and the coefficient.
