MOTION BLUR FREE CAPTURE OF LOW LIGHT HIGH DYNAMIC RANGE IMAGES

摘要

Embodiments of the disclosure compensate for global movement and in scene movement during image capture by a computing device. A sequence of images is accessed by the computing device. Accelerometer readings and/or gyroscope re adings corresponding to each of the accessed images are used by the computing device for calculating global movement among each of the accessed images. Each of the accessed images is re aligned based on the calculated global movement. The re aligned images are combined into a single output image. The intensity values of each of the pixels in the re aligned images are compared with the intensity values of e ach of the corresponding pixels in a reference image. Based on the comparison the intensity values associated with the pixels in the re aligned images are selectively accumulated to generate an output image that is blur free low light enhanced and high dynamic range.
