Samsung Just Made a 108MP Camera for Phones (thurrott.com) 63

Posted by msmash from the fwiw dept.
Samsung has announced a new image sensor for phones that breaks records. Built-in partnership with Xiaomi, the new Samsung ISOCELL Bright HMX is the world's first mobile image sensor that goes beyond 100 million pixels. From a report: At 108MP, the new sensor allows for higher quality pictures in different light conditions. The resolution, which Samsung says is equivalent to DSLR cameras, allows for "extremely sharp photographs rich in detail," according to the firm. It's the first mobile image sensor to adopt a large lens size of 1/1.33-inch that allows the lens to absorb more light, leading to better quality pictures in low-light conditions. There's also an intelligent Tetracell technology that uses a pixel-merging method to "imitate" big-pixel sensors, allowing phones to produce brighter 27MP images. [...] The image sensor is built to tackle video recording as well, with Samsung claiming no losses in field-of-view when recording videos at resolutions up to 6K at 30fps.

    Anyone who enjoys photography knows that sensor size is more important than megapixels. They also know that anyone who tells you a phone takes as good of pictures as a DSLR is lying. Open your image on a 4k monitor and you'll see. Anything you take on a camera will look better, especially indoors. In order for a phone to take as good of pics as a full frame DSLR, it would be huge and heavy. We don't lug 20 lbs of gear around to be hipsters. Heavy lenses and large sensors really do take much better pictures.

    The smallest full frame camera was recently announced by sigma. It's about the size of a late 90s cell phone without a lens. If you're willing to carry something that looks like a 90s Motorola flip phone, then you'll have DSLR quality. Until then, it's just marketing designed to fool naive consumers and drive people like me crazy.

    It's like speakers...sure a phone may have good speakers "for a phone," but nothing you want to carry in your pocket will sound as good as real speakers. The same applies for cameras. Samsung's sensor may be good "for a phone," but if you view it on any screen bigger than 4", you'll see a huge difference in quality between a real camera and one thrown on as an afterthought on your phone.

      Perfect example of sensor size, versus megapixel count....when that MS phone with the (I think it was) 20MP...there was a commercial, showing a couple teenagers at the back of a concert, took a photo of the stage area, then zoom/cropped the photo to make it look like they were right up front. THAT is the whole purpose of "more is better" in photography per se. To loose less detail, when you zoom/crop. It won't give you a "better" picture. Given the fact that even an APS-C sensor is 7-8 times the size of the largest smartphone sensor, the physics alone tells you it will have a better photo quality than a pinhole sensor camera. Along with that, stuffing more and more sensors that close, you end up with the signal to noise ratio going bonkers with crosstalk. Then, the smartphone camera software has to hopefully squish out the noise, which muddies the photo. BIGGER individual sensors, would be better than stuffing more and more into a pinhole sensor. Shoot, a GOOD quality 8MP sensor, it capable of an A3 or 11x17 size print, but who prints. But, as you say, this is all marketing...more is better, and unfortunately, consumers fall for it all the time.

    Two things:

    The tiny, cheap lenses built into cell phones are at this point the biggest factor in determining image quality, not the number of pixels. Is the resulting image sharp? Is it free from chromatic aberrations? Etc. Independent testing of the lens components is really a requirement at this point -- perhaps someone like DXOMARK can figure out a way to do it?.

    The more pixels you have in the same-sized sensor, the smaller they must necessarily be. This means by definition you have fewer photons hitting each pixel, which means you get more noise. Yes, you can somewhat offset that with fancy "noise reduction" math, but you can't cheat the physics either.

    108 MP in a cell phone is a stunt. Actually, in most "real" cameras, it's a stunt. Without decent glass optimized for what you're shooting, you can't take advantage of it, and you're just creating bigger files for no good reason.

    Other companies are moving away from playing the marketing game of packing more pixels in the sensor because it leads to worse images. After all, when the sensor's pixels get that small, any given pixel will receive a wildly different number of photons compared to its adjacent pixels, leading to a lot of noise across the image. Instead, others are marketing the exact opposite: that their pixels are getting bigger and bigger, leading to better quality images. I thought that this sort of "bigger = better" MP marketing had largely fallen by the wayside with Nokia's obsolescence, so it's a bit odd to see Samsung carrying the torch a few years later.

    The larger aperture is a no-brainer when trying to collect more photons. The "pixel merging" is what is known as "binning", a common technique with astrophotography CCDs where the light from a group of pixels (say, a 2x2 or 4x4 block of adjacent pixels) is summed to produce one brighter virtual ("binned") pixel. Binning's downside is that it eats away at the sensor's effective pixel array size and resolution, producing a narrower field of view (akin to a cropped sensor), but it seems that Samsung gets around this by brute force - just have a lot of pixels to begin with.

    • Field of view is a lens function - focal length of the lens versus imaging area of the sensor. Binning doesn't change the field of view it just reduces the sensor resolution.
