"Just" my smartphone camera; Computational Photography

After a long time, I have found what I was searching for; improving photographs with computers via multiple frames. I am interested in video for DATV (Digital Amateur TV) and was impressed with some of the image processing in CCTV security systems. However, most of this was based on single images. I had investigated improved day and night, long-distance photography as our house has panoramic views on the Queensland Gold Coast. Most of these techniques used multiple photos from a DSLR and post-processing with Photoshop or similar. Optical astronomers are well advanced.

However, the real progress seems to be driven by smartphones. Most people use their phones for photos now, with DSLRs a rarity outside tourist destinations. But phones have tiny cameras with small lenses and image sensor. Computational photography has allowed these small cameras to perform very well for particularly for images, but also video.
