If a display is 1920×1080 or 2 megapixels then wouldn’t anything above a 2MP camera be unnoticeable. Probably a stupid question but just wondering.
In: Technology
Yes, a regular HD display can’t display more than 2 MP at once.
But with more megapixels you’re able to zoom in further without losing quality.
in theory..
in practice camera is a crappy example because cams with 2mp sensors are generally shitty for host of other reasons, so in the end image will look like shit
Yes… basically.
But there are some definite benefits to having a camera that’s much higher-resolution than the screen on the same device:
* You can zoom and crop the image without losing a lot of clarity.
* “Image stabilization” relies on the camera having a bigger resolution than the video you’re recording. It allows the camera to “correct” the shakiness without adding black bars around the video.
* Very new phones now commonly use a technology called “pixel binning”, which reduces graininess in low-light photos, among other things. Basically, they use a camera with a ridiculously high pixel count like 100 MP to take a picture that’s resized down to an 8 or 12 MP photo that’s cleaner than it would be if it was taken with an 8 or 12 MP camera.
