Imaging apparatuses, mosaic image compositing methods, video stitching methods and edgemap generation methods

A mosaic image compositing method comprising:

• providing image data of a plurality of frames of an image;
• converting the image data to edgemap data;
• creating a mosaic image using image data from a plurality of the frames;
• and
• coordinating placement of the image data into the mosaic image using the edgemap data.

A video stitching method comprising:

• providing image data for a plurality of frames;
• converting the image data into edgemap data;
• first identifying a frame subset in a first frame using respective edgemap data of the first frame;
• second identifying the frame subset in a second frame using respective edgemap data of the second frame;
• providing movement information indicating movement between the first frame and the second frame responsive to the first identifying and the second identifying;
• and
• combining at least some of the image data of the second frame with mosaic data using the movement information.

An edgemap generation method comprising:

• providing image data for a plurality of frames and corresponding to a plurality of pixels for individual ones of the frames;
• defining a plurality of frame thresholds using the image data of the respective frames and wherein the frame thresholds correspond to respective ones of the frames;
• individually selecting the frames and the respective frame thresholds for the selected frames;
• individually comparing the image data of the selected frame with the respective selected frame threshold;
• and
• identifying selected pixels as comprising edgepoints responsive to the comparing for individual ones of the frames.
