There is still a big difference between Sony IMX519 and IMX586. If you want to make a comparison, of course, IMX586 will be the first choice. IMX519 will be used on hardware devices, not to mention photography technology. Next, let's take a look at the differences between Sony IMX519 and IMX586 photos.

Is it very different from IMX586?

It is obvious that the IMX586 CMOS wins in terms of hardware performance.

In fact, this question is a little bit lax. Because the actual imaging quality of a mobile phone mainly depends on the strength of the CMOS sensor, but a large part of it depends on the later algorithm optimization strength of the manufacturer. But then again, although the strength of the CMOS sensor can not determine the lower limit of a mobile phone imaging (the master leads the door to practice in the individual), it can definitely determine the upper limit of the camera strength of a mobile phone, so let's assume that the algorithm optimization is exactly the same, and evaluate the gap between Sony IMX519 and Sony IMX586 CMOS through some objective data.

The function of CMOS sensor and its decisive parameters

To put it simply, in mobile phones, the role of CMOS sensor is like our human eyes, its function is to receive optical signals and convert optical signals into electrical signals for ISP chip processing. So what are the external factors that affect the hardware strength of a CMOS sensor? In fact, there is only one thing, that is--

CMOS photosensitive area:

The photosensitive area is the most critical factor affecting the imaging quality of the CMOS sensor. Under the same pixel, the larger the photosensitive area, the larger the area of a single pixel, and the greater its ability to accept light signals, that is, the more light can be captured, then the higher the signal-to-noise ratio, the richer the details of the picture (what we see with the naked eye and the picture captured by the camera are actually the reflection of light. The capture of an image is actually the capture of light)

Comparison between Sony IMX519 and Sony IMX586

First of all, rule out one difference: although Samsung and Sony have changed the 18mm/ inch standard back to 16mm/ inch, there is no need to worry about the IMX519 and IMX586 products based on 16mm/ inches.

IMX519 parameters:

1max 2.6 inch photosensitive area, 1.22um single pixel area, 1600W effective pixels

IMX586 parameters:

1Xue 2 inch photosensitive area, 0.8um single pixel area, support multi-pixel synthesis 1.6um large pixels, 4800W effective pixels

In terms of parameters, IMX586 completely explodes IMX519. First of all, from the size of the CMOS sensor, IMX586 is much larger than IMX519, in the case of the same light source, IMX586 can have a larger amount of light input. In addition, IMX586 also has a four-in-one large-pixel technology, and multiple pixels can be called 1.6um super-large pixels. That means that when taking photos during the day, the details of the mobile phone with IMX586 will be more abundant. In terms of night imaging, phones with Sony IMX586 will also have brighter pictures and more details.

Summary:

To sum up, the hardware performance of Sony IMX586 is much better than that of IMX519, but the strength of a mobile phone to take pictures can not be judged by the strength of CMOS sensors alone, or from multi-dimensional considerations, the most important of which is the algorithm optimization strength of mobile phone manufacturers, such as aperture size, ISP chip strength and so on. One of the more typical is Google's Pixel2 with a single shot of IMX363 can be hard to resist a number of dual-camera mobile phones, this is the strength of algorithm optimization.

The above is about the difference between Sony IMX519 and IMX586.
