  • Fixed pattern noise removal method
    Patent number: 9148594
    Abstract: A fixed pattern noise removal method for an image sensor includes steps of calculating each compensation value corresponding to each pixel column according to a plurality of compensation pixel values of the each pixel column; and sampling a plurality of active pixel values in an active pixel area and compensating the plurality of active pixel values according to the each compensation value of the each pixel column, to generate a plurality of compensated active pixel values. A plurality of active pixels sense light to generate the plurality of active pixel values.
    Type: Grant

  • METHOD AND APPARATUS FOR ELIMINATING CHROMATIC ABERRATION
    Publication number: 20130223735
    Abstract: A method and an apparatus for eliminating chromatic aberration are provided. The method includes: calculating out a position weight of a pixel according to the position of the pixel in an image, calculating out an edge response of the pixel and converting a chrominance of the image pixel into a hue; using the edge response of the pixel to calculate out a hue range; and finally correcting the hue of the image pixel by using the position weight, the edge response and/or the hue range.
