Abstract:
According to one embodiment, an image processing apparatus includes a defect correction unit, a noise reduction processing unit, and an output selection unit. The defect correction unit includes a contrast determination unit and an illuminance determination unit. The output selection unit selects the output from the defect correction unit when a target pixel is determined to be a defect. The defect correction unit enables a correction value to be output as a signal value which is applied to the target pixel in accordance with the contrast determination and the illuminance determination.
