I, and roughly 1% of males, have protanomalous trichromatic vision. That means my "long wavelength cones" are actually duplicate medium wavelength cones that are shifted longer but not completely to red like normal L-cones. Under moonlight for roughly 1/3 of the lunar month I can see roughly 20% better than normal human vision. That's because for only 1/3 of the lunar month is the moon bright enough to allow my enhanced cone cells to see more under the spectrum of light that moonlight produces (a reflection of sunlight with valleys in 2 specific wavelengths). I have night vision as far as humans are genetically capable.

@@ThePhysicalReaction Not him but I have ancestry from hose more northern latitudes, lighter eyes, and a similar experience at night. On a typical moonless semi-rural night away from artificial lighting my night vision is about maybe half the intensity of what’s shown in the color “night vision” at the start, with a modest amount of color, but more washed out. An interesting factoid is that most animals seem to not be able to see things that are standing still or have little relative motion. The tapetum and large iris size gives them excellent sensitivity, but they likely suffer from poor visual acuity. It’s resulted in some sphincter-puckering moments such as my dog and a skunk “booping snoots” in the dark when I wasn’t paying attention since they were walking directly towards each other. However if there is relative motion such as a rabbit taking off the dog can easily see it even when it’s completely pitch black to me. But, it does show why deer stand still at night. I can make them out, but the dog can’t, and I suspect it might be similar for wolves,

Yes and you can stack pixels in a sliding window to get movement and it also helps reduce the noise allowing you to use higher gains. This is not a new technique.

​​@@dr_jaymz I am working on a solution that takes still color data at a 3-5 second rate from a wide-angle camera and a separate monochromatic video feed at 6-12 FPS to achieve the same. Some multi-cam Android phones allow you to fine-tune the shutter speed and other parameters of each camera separately, so this is quite accessible in terms of technology required. As you've already guessed, the fairly "low quality" input is then fed to a series of algorithms and models that denoise and auto-balance, then increase the framerate and infer colors from the 3-5 second wide-angle color references. The wide angle also helps immensely with colour accuracy in moving shots as it captures stuff that are off-view for the motion camera. Quality will be comparable to this in the end product and it will be able run on a mid-range device with up to 24FPS.

No, telescopes just use a massive imager, and then a really big mirror to catch light, plus exposures that can be measured in hours.

Galaxies are so far away from us that they either look like single stars in our galaxy, or they're not visible at all. In other words a telescope like hubble can focus on a literally black part of the sky and after exposing that section of sky for long enough, objects will become visible. As for how they focus, the telescope has star trackers and gyroscopes that keep it it pointed at the exact same location in the sky as it orbits the earth.

But don't increase it too much or you will also catch the movement of the stars / movement through the rotation of earth :D

When you were talking about ways to get more light in a frame my first thought was just to multiply the amount of cameras

Can you show how it looks when someone is moving around? Are they still recognizable?

4:30 Shows partly how this works with a kind of persistence of vision.I have reolink cameras. The model I have shows a very clear 4k image at night even in low light. It seems to use a slight image delay to process each frame and build up light information for each frame by using data from previous frames (he mentioned you cant have longer exposure than the frame rate, well it seems to get round it by a kind of "persistence of vision"). You can see this in the timestamp above. There is a weird delay (similar to motion blur) when his hand, camera and trees move. This is great for things that are still or slow moving, it shows number plates and people clearly, however when they move the effect is lost somewhat as the frames dont then have enough data in that spot to use. It still works much better than my old security camera.

But can it be used with ZERO CLOUD ACCESS?

What about using multiple frequencies of IR light, and then shifting the frequencies up digitally?
