Abstract: The present invention discloses a new method for analyzing, modifying, and distributing digital images and video in a quick, efficient, practical and/or cost-effective way. The method of processing video can take a different region or object and replace the pixels in the frames of the scenes that comprise the features and characteristics of the identified region or object with a different set of pixels. The replacement or other customizations of the frames and scenes lead to a naturally integrated video or image which is indistinguishable by the human eye or other visual system. In one embodiment, this invention can be used to provide different advertising elements into an image or set of images for different viewers, or to enable a viewer to control elements within a video and add their own preference or other elements.

Abstract: Embodiments relate to an image processing circuit able to perform image fusion on received images in at least a first mode for fusing demosaiced and downscaled image data, and a second mode for fusing raw image data. Raw image data is received from an image sensor in Bayer RGB format. In the first mode, the raw image data is demosaiced and resampled prior to undergoing image fusion. On the other hand, in the second raw image mode, the image processing circuit performs image fusion on the raw Bayer image data, and demosaics and resamples the generated fused raw Bayer image. This may ensure a cleaner image signal for image fusion, but consumes more memory. The image processing circuit is configured to support both modes of operation, allowing for fused images to be generated to satisfy the requirements of different applications.
