Image compensation method and image acquisition device using the same |
摘要 |
An image compensation method adapted to reduce noise of a first image captured by an image acquisition device at a high ISO mode. The image compensation method includes the following steps. A Bayer pattern is obtained from the first image. A green pixel signal, a low-resolution binned original luminance signal, and an original chrominance signal are respectively generated according to the Bayer pattern. A high-resolution analog luminance signal is generated by using the green pixel signal. The high-resolution analog luminance signal and the low-resolution binned original luminance signal are combined, and a compensated high-resolution luminance signal is output. A second image is generated by combining the compensated high-resolution luminance signal and the original low-noise chrominance signal. |
