Abstract: Techniques to temporally filter images via a filtering weight computation are disclosed. A first image having a first timestamp and a second image having a second timestamp are acquired. These images are generated by a camera, and the first timestamp is before the second timestamp. A motion compensation (MC) operation is performed on the first image to produce an MC image. A difference image is generated using the MC image and the second image. The difference image reflects differences in intensities that exist between the two images. A local weight map is generated based on those differences. A global weight map is generated based on certain IMU data. A final weight map is generated based on a combination of the local weight map and the global weight map. The final weight map is used to generate a filtered image.

Abstract: The present disclosure discloses an image flicker detection method that includes the steps outlined below. An image retrieving is performed to retrieve a current image. A current variation ratio between first rows of pixels of the current image and second rows of pixels in a previous image is calculated. When both the current variation ratio and a previous variation ratio are determined to be larger than a ratio threshold, a detected flicker number is incremented. When the detected flicker number is determined to be larger than a flicker number threshold, a flicker condition is determined to occur. When the detected flicker number is determined to be not larger than the flicker number threshold, the current image becomes the previous image and the current variation ratio becomes the previous variation ratio such that a next image becomes the current image to repeat the above steps.
