Qualcomm says its chipsets always supported 192MP sensors; phones with 100MP, 64MP cameras coming in late 2019

Avant d’acquérir un smartphone pliable, il faut toujours analyse les différents appareils disponibles sur le marché. Lequel, permettra vraiment de regarder les actualité tous les jours de manière confortable ?

  1. >Qualcomm is working on its own implementation of HDR10 video recording with frame-by-frame and scene-by-scene metadata, and that it will come with the company’s Snapdragon 865 chipset later this year.

    « Later this year » as in before December or at the usual December announcement?

  2. They must’ve found an easy way of increasing megapixels so that’s the route they’re taking. Just like with increasing screen size.

    All these megapixels mean nothing if you don’t have a good sensor behind them. I wish they’d go back to times when they were experimenting with bigger sensors.

  3. With smartphone cameras, higher resolution sensors often just overall hurts the image quality.

    Smaller pixels will have a lower SNR, thus you lose inter-tonal detail and fine detail. this is why if you take a smartphone with a 20+ megapixel sensor, and zoom it 1:1, there is very little fine detail, even in direct sunlight and the lowest ISO.

    There are 2 major reasons for this. As mentioned above, the tiny pixels have bad SNR, but a second massive issue is that no affordable lens has the resolving ability to not behave like a low-pass filter for the sensor. If we look at cameras like the Nikon D850, there are only 2-3 lenses on the market right now that that allows allows you to get close to just 40 megapixels worth of actual detail in the frame, and those lenses are insanely expensive. Furthermore if we take those insanely expensive lenses and put them on a crop sensor camera such as a D7200 where we are dealing with a higher pixel density, then suddenly we are losing a bunch of effective resolution.

    The highest pixel density in camera sensors available today that are commonly used, are found in smartphones, and no lens exists that can resolve enough detail for such a high pixel density.

    While a higher resolution can bring about some additional detail in portions of the frame since all lenses will have a small « sweet spot » in the frame, and more pixels means more in the « sweet spot », but overall, it is a very small improvement and as soon as you leave the base ISO, all of that benefit disappears.

    A 100 megapixel sensor in a smartphone will be pure marketing.

    Even at 12 megapixels, no smartphone camera has a lens that resolves that much detail.
    For example, take a camera like a Nikon D700 (full frame 12.1 megapixel camera) and compare its raw files to the raw files from the current best 12 megapixel smartphone cameras, and you will see that even with a full frame kit lens (entry level stuff), the DSLR will have far more detail. The difference is almost entirely due to the lens (if you ignore the DSLR’s better dynamic range and tonal quality).

    If you were to take the pixel densities of most common smartphones and scaled them up to the size of sensors you would encounter in a good DSLR, you will be looking at 90-150 megapixel sensors.

    At high pixel densities, the resolving power of the lens is a huge concern, this is why if you take an image with a 50 megapixel medium format camera, and the same image with a full frame DSLR of a similar resolution (both using high quality lenses) the medium format image will have better detail. The main reason is that a medium format sensor paired with a good lens is often able to fully deliver a luminance detail level that matches the sensor output resolution.

  4. This means Qualcoom chips could support my ideal camera setup of four 48MP (0.8 micron) 1/2 inch sensors. Where combining the data from all the sensors would be similar to a 48MP (1.6 micron) sensor. Through pixel binning it would be the similar to a 12MP (3.2 micron) sensor. A setup like this would have significantly better low light performance than any other smartphone, and would have up to 4x zoom at 12MP, at comparable quality to the primary rear camera of other smartphones.

  5. To be honest I’m the type of guy that like to look at the tiny details on pictures. With a 100mp camera you won’t need that limited telephoto zooming nonsense.

    We can use some of that Google AI magic to make pictures look good a again.

  6. I can see the use of good 8k video for large 8k TV’s or taking large stills of space/ocean/scenery where you can crop out certain areas to get a good picture of those areas.

  7. We’ve seriously run out of ideas. It’s very obvious that the industry is stagnating because everyone’s fresh out of ideas or a lot of the ideas are in R&d for like the next 10 years.

  8. The problem with the previous chipset (835 and 845) is when those megapixels start moving aka video. Without a good memory subsystem, video encoding becomes less efficient and things like 60 fps at higher resolution (4K) becomes less doable with lesser encoder.

    I don’t think it has, fundamentally, changed with the 855 (aka the memory subsystem- I might be wrong). Only that the hardware encoder (Spectra 380) is a lot more capable.
