Today, PhoneArena came in with an interesting interview with Zeiss CEO Dr. Michael Kaschke. He said that the slim body of the smartphone limits the potential of the camera lens. However, although the hardware is limited, the algorithm processing can also help the camera to take good photos.
According to Dr. Michael Kaschke, the combination of camera lenses and algorithms on the Google Pixel series allows them to take great photos. It should be noted that the number of cameras on the back of the phone does not necessarily improve quality. In light of this, Michael Kaschke said that smartphone cameras always face two problems. One is the problem of taking photos in low light conditions. Second, there is a lack of excellent telescopic zoom capability.
Regarding the pixel problem of the smartphone camera, Michael Kaschke said that 64MP is ‘excess’. The 40MP is ‘more than enough.’
He pointed out that the optical quality of the Nokia 9 PureView is currently the best. At the same time, he revealed that the use of multi-lens and digital image processing on smartphones is still in its infancy. The only way smartphone makers can differentiate themselves is by upgrading lens sensors.
In the interview, Michael Kaschke said he believes that Samsung’s 64-megapixel sensor is ‘over-fire’. Having said that, he thinks that the 64MP sensor announced by Samsung is overkill. 40MP is ‘already more than enough.’ The full-frame sensors in use today divide a large number of pixels into smaller and smaller pixels creating too much noise.
‘The optical quality on the phone [Nokia 9 PureView] is probably one of the best that you can find. But as I said before, the optics, the smartphone, and the software have to work perfectly together. I see that computational imaging is still in its early stage and multi-lens photography on the smartphone is just in the making, and I still think we all have to go for it…“More pixels are not necessarily better. Why? If you stay with the full-frame sensor and divide that sensor into more and more pixels, the pixels become smaller and smaller, and then you get into a noise problem. I think for most of the applications, also serious professional applications, my guess would be the 40MP is already more than enough.’-Michael Kaschke, President and CEO, Zeiss Group
