Abstract:
Methods and systems for increasing the effective dynamic range of an image sensor are disclosed. Each pixel in the sensor is exposed for a respective first exposure time. Each pixel's response to the respective first exposure is measured and compared to threshold values. Based on the pixel's response to the respective first exposure time, an optimal exposure is calculated for each pixel. The optimal exposure time is applied to each pixel by utilizing row-enabled and column-enabled signals at each pixel within the sensor.
