SYSTEM AND METHOD TO GENERATE HIGH DYNAMIC RANGE IMAGES WITH REDUCED GHOSTING AND MOTION BLUR

摘要

Methods, devices, and computer program products for generating high dynamic range images with reduced ghosting and motion blur are disclosed herein. In some aspects, methods of detecting areas of motion blur in an image are disclosed. This detection may be based on either a row-based approach, or a patch-based approach. These approaches may be used to classify images or portions of images as being either blurry or sharp, based upon a threshold value. The threshold value may be determined empirically.

1. A method of determining whether the blurriness of an image renders it unsuitable for constructing a high-dynamic range image, the method comprising:
sampling two or more rows of the image; detecting edges in each selected row using difference of Gaussians for each row at two of more scales; calculating an average blurriness value for an image, the average blurriness value based on an average of the blurriness value for each of the sampled rows; and comparing the average blurriness value to a threshold value to determine if the blurriness of an image renders it unusable to use to construct a high-dynamic range image.
