What frame rates and image sizes work for grayscale video mode?
FLEX:V100R2, FLEX:V100 & SLIM:V100, V120:SLIM: It is only possible to get uncompressed 640 x 480 grayscale at 100 FPS exposure rate with 50% frame decimation under some conditions. To achieve that, it is usually necessary to have only a single camera connected to your system’s USB port and have no additional USB hubs plugged into the system. The down-sampled modes work under more diverse system configurations. They provide 320 x 240 and 160 x 120 grayscale at 100 FPS exposure with no frame decimation under most conditions. FLEX:V100R2 and V120:SLIM cameras operating in MJPEG grayscale mode can typically operate at or near the 100 FPS frame rate (at 640 x 480 image size) without issue on most systems and configurations. FLEX:C120: It is usually possible to get 355 x 288 grayscale at 120 FPS. Under heavier USB load with additional cameras it may be necessary to set the Frame decimation mode to 50% or greater. Additionally, using the windowing feature to reduce the horizontal size of the
