Abstract
An image processing apparatus includes a gain calculation unit that calculates a gain for each of a plurality of pixels of an image signal, respectively, and an addition unit that adds the gain for each pixel to the corresponding pixel of the plurality of pixels of the image signal. The gain calculation unit includes a first order differential operation unit that calculates a first value from first order differential of the image signal for each of the plurality of pixels and second order differential operation unit that calculates a second value from a second order differential of the image signal for each of the plurality of pixels, and calculates the gains for each pixel based on the first and second values for each pixel.
