Abstract
An image sensor device is provided to effectively improve the signal discrimination of sensed/sampled pixel values/signals in the image sensor device operating in a dark condition as well as effectively avoiding signal saturation when such image sensor device operates in a light/bright condition. Such image sensor device, when operating in dark/light conditions, can perform the exposure operation to get/sample accurate pixel image signal and pixel reset signal for only one time without estimating the pixel image signal and pixel reset signal by performing the exposure operation twice.
