23. 0 cameras send 3 pixel data per CameraLink clock cycle in parallel The framegrabber in 24 bit RGB mode however processes these 3 pixels as one RGB pixel In the RGB mode the memory management of a 24bit colour image has to be considered Blue is usually stored at address 0 green at address 1 and red at address 2 and so on in this order Since the blue channel in the camera link standard is located at tap 2 pixel 2 and the red channel at tap 0 pixel 0 pixel 0 amp 2 would be stored in the wrong order in the memory The MV1 D1312 1 240 cameras provide a BGR mode This swaps pixels 0 amp 2 at the camera link interface and the pixels then have the proper order in the memory In this configuration an image can be grabbed in 24 bit RGB mode and the RGB buffer can be read out as an 8 bit monochrome buffer without the need of copying the pixel data ce Ask Photonfocus support lt support photonfocus com gt if you have problem using the 3 tap mode 3 4 Frame Grabber relevant Configuration 21 3 Product Specification 22 4 Functionality This chapter serves as an overview of the camera configuration modes and explains camera features The goal is to describe what can be done with the camera The setup of the MV1 D1312 l series cameras is explained in later chapters 4 1 Image Acquisition 4 1 1 Readout Modes The MV1 D1312 l CMOS cameras provide two different readout modes Sequential readout Frame time is the sum of
