IMAGE SENSOR AND METHOD AND APPARATUS FOR REMOVING SUNSPOT OF THE SAME |
摘要 |
A method for removing a sunspot of an image sensor, an apparatus for removing a sunspot of an image sensor and an image sensor are provided. The method includes: obtaining reset sampling signal values of pixel units in a pixel array of the image sensor; for each of the reset sampling signal values, determining whether the reset sampling signal value is less than a predetermined sampling signal threshold, and generating a comparing signal when the reset sampling signal value is less than the predetermined sampling signal threshold; generating location information of the pixel unit corresponding to the reset sampling signal value according to the comparing signal; and replacing the reset sampling signal value corresponding to the location information with a maximum brightness value. |
