"Camera sensors" have been able to do this since the dawn of digital photography, seeing as these parameters are so fundamental even for selfies. A sensor that can't adjust exposure time is one that cannot function in almost any light.

Phone cameras are a special category. Sure there are digital cameras that can do it. But low-profile low-power miniaturized camera sensors?

  Yeah iPhone cameras can do all that stuff. Notice that iPhones have long exposure modes for astrophotography, but still also take high frame rate “slomo” videos. MEMS autofocus has been available on iPhones for almost a decade and voice coil motor autofocus before that. https://www.google.com/search?client=safari&hl=en-us&sxsrf=APwXEdfx7ajzhkKVcXqb4p-TXUPeOEyheA:1682367652392&q=mems+autofocus+smartphone&tbm=isch&sa=X&ved=2ahUKEwiairXyq8P-AhXLlmoFHemcDMUQ0pQJegQIDhAB&biw=428&bih=746&dpr=3#imgrc=Xk8cVHEAfhFMCM&lnspr=W10= https://www.google.com/search?client=safari&hl=en-us&sxsrf=A...

    Here's the comment I was remembering: Rich Altmaier 3:23 PM (5 minutes ago) to me The sensors Intel was producing, now about 7 year ago, did not support capturing the full set of frame pixels at one time. Rather pixels could be copied into backing store from just one pixel row at one moment, then read out, then copy the next row and read out. So the single row of pixels was from the same moment in time, and subsequent rows had to spread over about 1/120 second of time. So all images were time delayed from top to bottom of the frame. This method, common to smart phones, is the reason fast moving objects appear bent. e.g. helicopter blades are bent in mobile video. Secondly I wanted an enhancement, not available at that time in any modern DSLR camera, to adjust the capture image brightness based on ambient illumination changes. This would prevent the typical gym lighting, fluorescent oscillating at 1/120s, from a beat frequency with the video shutter, showing slow moving bands of light/dark across the screen. Rich

  My Galaxy Note 9 can do it. I use the OpenCamera app, which gives manual exposure control, manual shutter speed control, manual focus, and can shoot in raw. Of course auto modes still work. That's a nearly 5 year old phone, though it was rather high-end for the time.
