Abstract
A method of implementing high dynamic range bin algorithm in an image sensor including a pixel array with a first super row having a first integration time and a second super row having a second integration time is described. The method starts by reading out image data from the first super row into a counter. Image data from the first super row is multiplied by a factor to obtain multiplied data. The factor is a ratio between the first and the second integration times. The multiplied data is then compared with a predetermined data. The image data from the second super row is readout into the counter. If the multiplied data is larger than the predetermined data, the multiplied data from the first super row is stored in the counter. If not, the image data from the second super row is stored. Other embodiments are also described.
