  • Image processing apparatus and camera module
    Patent number: 8305459
    Abstract: According to the Embodiments, an Image Processing apparatus includes a pixel interpolation processing unit. The pixel interpolation processing unit generates a sensitivity level value through addition of a first frequency range component of an image signal for a lacking color component and a second frequency range component of a frequency band lower than the first frequency range component. The pixel interpolation processing unit adjusts a ratio of the first frequency range component to be added to the second frequency range component.
