Questions on differences on same 2D capture settings

[Laobyy]

I use the exact same settings, but the image I take using Python scripts still looks different from the image I take using Zivid Studio. I export the settings file from Zivid Studio so the settings should be same. Here are my sample settings:
version:
serializer: 1
data: 5
Settings2D:
Acquisitions:
- Acquisition:
Aperture: 3.00
Brightness: 0
ExposureTime: 15000
Gain: 3
Processing:
Color:
Balance:
Blue: 1
Green: 1
Red: 1
Gamma: 1
Sampling:
Color: rgb
Pixel: all

Can someone tell me why this difference always occur?

Hi,

Which Zivid SDK version are you using?

Note that you can get and save an image in two color spaces: Linear RGB and sRGB

zivid-python-samples/source/camera/basic/capture_2d.py

Lines 48 to 59 in dfc9a98

	print("Getting color image (linear RGB color space)")
	image = frame_2d.image_rgba()
	rgba = image.copy_data()
	pixel_row = 100
	pixel_col = 50
	pixel = rgba[pixel_row, pixel_col]
	print(f"Color at pixel ({pixel_row},{pixel_col}): R:{pixel[0]} G:{pixel[1]} B:{pixel[2]} A:{pixel[3]}")
	image_file = "ImageRGB.png"
	print(f"Saving 2D color image (linear RGB color space) to file: {image_file}")
	image.save(image_file)

zivid-python-samples/source/camera/basic/capture_2d.py

Lines 61 to 70 in dfc9a98

	print("Getting color image (sRGB color space)")
	image_srgb = frame_2d.image_srgb()
	srgb = image_srgb.copy_data()
	pixel = srgb[pixel_row, pixel_col]
	print(f"Color at pixel ({pixel_row},{pixel_col}): R:{pixel[0]} G:{pixel[1]} B:{pixel[2]} A:{pixel[3]}")
	image_srgb_file = "ImageSRGB.png"
	print(f"Saving 2D color image (sRGB color space) to file: {image_srgb_file}")
	image_srgb.save(image_srgb_file)

Zivid Studio displays in sRGB.
