An image processing method is provided. The method includes the step of comparing each of the input pixels in an input image to a corresponding buffered pixel in a buffered image, and computing the difference value between the input pixel value of the input pixel and the buffered pixel value of the buffered pixel. The method further includes the step of generating a blended image based on the input pixel values and the corresponding difference values. The method further includes the step of determining whether a criterion associated with the difference value is met, for each of the difference values. The method further includes the step of updating, for each of the buffered pixels in the buffered image, the buffered pixel value based on the corresponding input pixel value if the criterion is met, and keeping the buffered pixel value unchanged if the criterion is not met.

Image processing method and image processing device

A video capture method includes: controlling an image sensor to capture a plurality of first sensor output frames at a first frame rate during a first period; during the first period, checking if a motion blur condition is met; in response to the motion blur condition being met during the first period, controlling the image sensor to capture a plurality of second sensor output frames at a second frame rate during a second period following the first period, wherein the second frame rate is higher than the first frame rate; and processing consecutive sensor output frames captured by the image sensor during the first period and the second period, to generate a plurality of output frames.

Method and apparatus for dynamically changing frame rate of sensor output frames according to whether motion blur condition is met

A video controller and method for performing tone-mapping of high-dynamic-range (HDR) video are provided. The video controller includes: a color-space converter, arranged to receive an input high-dynamic-range (HDR) video signal and perform a color space conversion on the input HDR video signal to obtain a first video signal having a first gamma curve; a de-gamma unit, arranged to apply a second gamma curve on the first video signal to compensate the first gamma curve to obtain a second video signal; a first histogram calculator, arranged to calculate a first histogram of a current frame of the second video signal; and a tone-mapping unit, arranged to apply a tone-mapping curve on the current frame of the second video signal according to a histogram of a previous frame of the second video signal to generate an output video signal.
