There are a surprising number of patents covering the devices we use every day--and digital cameras are no exception. I am posting a series of threads discussing patents covering various technologies in Pentax and Ricoh cameras for discussion. You might be surprised about the technologies covered.
The patent I'll be discussing in this thread covers the handheld HDRI feature first introduced in the Pentax K-r. While previous models have been able to capture HDR images with the aid of a tripod, the K-r was the first model able to generate usable HDR images even when shooting handheld.
The relevant patent is
US8305453, Imaging apparatus and HDRI method. It covers a method for selecting a "reference area", and using it as a basis for aligning the images together before merging them to HDR.
Questions, thoughts, or comments?
