Abstract
The invention relates to an image sensing device and an image sensing method thereof. The image sensing device includes: an image sensing array and an image processing circuit. The image sensing array generates multiple pixel data, and the pixel data includes a first pixel data and a second pixel data. The first pixel data is generated by exposing for a first exposure time, the second pixel data is generated by exposing for a second exposure time, and the first exposure time is shorter than the second exposure time. The image processing circuit executes an automatic exposure convergence operation with the first pixel data to generate new exposure parameters for the automatic exposure convergence operation. The second exposure time is adjusted according to the new exposure parameters, so that the second pixel data is pixel data with changed exposure time.
