The present invention relates to a dynamic image generating method and a dynamic image sensor thereof. The dynamic image sensor includes a first exposure pixel, a second exposure pixel and an image processing module. The dynamic image sensor applies the dynamic image generating method, which generates the default short-exposure image signal by exposing the first exposure pixel for default short-exposure time, and exposing the second exposure pixel for default long-exposure time to generate the default long-exposure image signal. The image processing module confirms whether the default short-exposure image and the default long-exposure image signals are between the lower and upper limits of pinching. If so, the optimal short-exposure time and the optimal long-exposure time are generated; otherwise, increase the default short-exposure time by a short-exposure fixed value or decrease the default long-exposure time by a long-exposure fixed value, and repeat until the optimal short-exposure and long-exposure times are obtained.

Dynamic image generating method and dynamic image sensor thereof

The present invention relates to a method of image fusion, which uses the brightness difference of the current frame and the previous frame to determine whether the pixel in a frame image is static or dynamic. If the current pixel is static, the previous corresponding pixel is superimposed onto the current pixel; if the current pixel is dynamic, the previous corresponding pixel is replaced with the current pixel.

Method of image fusion

The present invention provides an image sensing device and an image sensing method. The image sensing device comprises an image sensing array and an image processing circuit. The image sensing array obtains a first frame for a test object, and the first frame comprises a plurality of first pixel values. The image processing circuit analyzes the first frame, and generate an overexposure area for the first pixel values greater than a first threshold in the first frame. Then, the image sensor array obtains a second frame for the overexposure area, and the second frame comprises a plurality of second pixel values. The image processing circuit performs a detection processing on all the first pixel values in the first frame, which retains the first pixel values outside of the overexposure area in the first frame, and replaces the first pixel values in the overexposure area with the second pixel values.
