Column noise reduction device and method thereof |
摘要 |
An image sensor and method for column noise reduction may reduce decrease the visibility of fixed pattern noise. The image sensor may include an analog processing circuit and a digital processing circuit. The analog processing circuit may be configured to selectively permutate columns of pixel data based on a permutation signal, each column of pixel data including pixel data associated with at least one pixel in a pixel array. The digital processing circuit may be configured to convert the permutated pixel data into digital data and selectively re-order the columns of pixel data based on the permutation signal. The method for capturing an image may include selectively permutating columns of analog pixel data based on a permutation signal, converting the permutated analog pixel data into the digital domain and selectively re-ordering columns of the digital permutated pixel data based on the permutation signal. |
