Abstract
The disclosure relates to technology for processing images to detect LED on pulses within the images. An image processing device and method includes a fusion processor and process configured to receive the sequential long and short exposure images and output a fusion image including added corresponding regions of adjacent sequential long and short exposure images. The image processing device and method also includes an LED detection processor and method configured to receive the fusion image, a WDR image and the sequential long and short exposure images and output a control signal indicating whether each corresponding region includes an LED flicker or motion. The image processing device and method also includes a blending processor and method responsive to the control signal to generate a blended image for the sequential long and short exposure images.
