서로 처리 메커니즘이 전혀 다르지만

990에 더 좋은 평가를 내리더라고요

Last year we saw some larger camera quality differences between the Exynos and Snapdragon variants of the S10+; these differences slowly disappeared over the course of the year over numerous software updates, but there still remained some discrepancies here and there in terms of the software processing. 

지난해에는 9820이 855에 비해 명백히 열세였습니다

At 10x magnification we again see the two S20 Ultra shots being similar in exposure, however there’s again differences in the detail. Here it’s more evident that the Snapdragon unit is using post-processed sharpening to the image, and there also appears to be some smearing of details as the Exynos unit does achieve to maintain some better textures on some elements.

Between the Snapdragon and Exynos S20U’s, the Qualcomm variant continues to showcase more post-processed sharpening throughout the scene on all camera modules. On both wide and ultra-wide shots, we see the Exynos able to retain better definition of textures in the brighter elements on the scene such as on the small and big concrete towers.

스냅드래곤은 후처리를 통해 더 샤프하게 처리를 하는 특성이 있고, 엑시노스는 질감을 더 잘 보존하지만 디테일한 측면을 어느정도 뭉게버리는 특성을 가집니다

While the Snapdragon does pop out more and has more contrast in the details, it’s quite exaggerated and doesn’t feel as natural as the unsharpened results of the Exynos S20U.

국내판 S20이 상당히 샤프하게 후처리를 한다는 평가를 많이 받는데, 아마 이러한 특성이 꽤 작용했던거 같네요

아난드텍 측에서는 양측의 결과물중 우열관계를 파악하기는 어렵다고 했으나, 상당히 과장되보인다는 평을 남겼네요

Both phones are able to capture significantly more detail than in their default 12MP modes, however there a very stark differences between the Snapdragon and Exynos phones, with the latter being able to produce a much higher quality result with far more natural detail. I don’t know exactly what’s happening here, but it’s as if the Snapdragon picture was lower resolution and scaled up to 108MP, whereas the Exynos unit is closer to a native resolution shot.

사진중에 어떤 사진은 스냅 측에서 12MP로 찍어서 108MP로 스케일 업 한듯한 결과물이 있었는데 왜 그랬는지는 의문이라고 하더라고요.

The S20 Ultras are quite different here in terms of their color renditions, with the Snapdragon being quite saturated. There’s also differences in exposure – although both phones were similar in their exposure time at 1/124 and 1/135th second, the Snapdragon chose ISO16 while the Exynos chose ISO50. There is some evident change in the HDR processing as the Exynos is able to better preserve the highlight of the sky and that part of the trees whereas it’s blown out on the Snapdragon.

I don’t know what’s happening on the Exynos S20 Ultra unit’s Ultra-Wide, but there’s this blob of blurriness in the very center of the image on both phones. It’s as if the phone was trying to do some image fusion with another sensor but failing at it spectacularly. This isn’t present on the S20+.

물론 엑시노스가 이상한 결과물을 뱉어낸 사진도 있습니다

Overall Daylight Conclusion – Somewhat Disappointing

The S20 Ultra’s 108MP main camera was quite unconvincing to me in the daylight shots. There are several layers that we have to peel apart here. First of all, there are very obvious processing differences between the Snapdragon and Exynos models this year. While on the S10 series this was in favor of the Snapdragon, I feel the other way around for the S20 series as the sharpening on the S20 Ultra here has gone absolutely haywire on all the camera’s modules, going beyond what one would consider an improvement of picture quality into the realm of actually being detrimental to the picture. The Exynos variant here seemingly has no sharpening processing at all, and it feels a ton more natural.

다 퍼올수는 없는 노릇이고 요약해보면 주광에서는 엑시노스의 ISP가 더 좋다는 평입니다

Overall Low-Light Conclusion

Overall, I think the S20’s software processing in low-light is quite a mess. We saw some scenes where the new S20 phones are clearly better than other phones, but this seemingly only happens in medium-light conditions, as the darker you get, the worse the results. There’s also some quite large differences in the software processing between the Snapdragon and Exynos phones this year, this time around it’s the Exynos model which is very clearly better in the majority of scenarios as the Snapdragon variant very often blurs out details and textures.

저조도에서도 엑시노스 990이 더 좋은 결과물을 보여준다고 하네요

물론 이게 ISP 차이인지, 아니면 ISP를 사용하는 방식의 차이인지는 잘 모르지만

S10에서는 9820이 저조한 결과물을 보여줬다면 S20에는 865가 더 저조한 결과물을 보여줬다는 것은 확실한 듯 하네요.
