Reduction of motion-induced blur in images
First Claim
Patent Images
1. An image capture device for capturing images that are intentionally underexposed in order to reduce motion-related blur, the image capture device comprising:
- a photosensor array;
a controller for controlling the array to capture images that are intentionally and selectively underexposed in order to reduce motion-related blur;
means for detecting motion of objects of the images that can cause motion-induced image blur; and
means for detecting lighting conditions;
wherein the controller is configured to evaluate the detected lighting conditions and the detected motion to determine, before the underexposed images are being captured by the photo sensor array, whether the images should be intentionally underexposed based on the detected lighting conditions and the detected motion.

Abstract
A device captures images that are intentionally underexposed to reduce motion-related blur. Image processing is performed on the underexposed images. The processing includes reducing noise and increasing gain in the underexposed images.

12. An image capture device comprising:
-
means for capturing an image that is intentionally and selectively underexposed, the image being underexposed to reduce motion-related blur; means for reducing noise and increasing gain in the underexposed image; a controller means for controlling the means for capturing to capture the image that is intentionally underexposed; means for detecting motion of an object of the image that can cause motion-induced image blur; and means for detecting lighting conditions;
wherein the controller means is configured to evaluate the detected lighting conditions and the detected motion to determine, before the underexposed image is being captured by the means for capturing an image, whether the image should be intentionally underexposed based on the detected lighting conditions and the detected motion. - View Dependent Claims (13)
