2D color image inconsistency after updating Zivid SDK

Problem

Zivid camera outputs different color images after updating Zivid SDK using the same 2D color settings.

Possible cause

For Zivid 2 after updating to SDK 2.8

Zivid 2의 색상 균형 계산은 SDK 2.8에서 업데이트되었습니다. 즉, SDK를 업데이트한 후 지정된 픽셀의 색상 값이 다를 수 있습니다. Color Balance 값이 1보다 큰 경우에만 불일치가 있습니다. 게인 값이 높을수록 차이가 더 두드러집니다. 아래 이미지는 SDK 2.7과 SDK 2.8 간의 불일치를 보여줍니다.

For all cameras after updating to SDK 2.11

In SDK 2.11, Zivid Studio represents colors in sRGB, instead of linear RGB. The histogram and the RGB color channel values for a given pixel are still displayed in linear color space. The image below shows the same image represented in sRGB and linear RGB.

Monitors typically expect images in sRGB space and will do an inverse gamma correction before interpreting the image for display. For more information, go to 2D Color Spaces and Output Formats.

Solution

If the color balance is wrong, re-tune the color balance gain values either manually or by following our Adjusting Color Balance guide.
