Video Modes

FL3-U3-88S2C-C FL3-U3-120S3C-C
Mode 0 Resolution: 4096 x 2160
Mode 0 allows only for specifying a region of interest, and does not perform any binning.
Frame rate does not increase when ROI size is reduced. Global Reset is available if using Standard Trigger Mode.
Resolution: 4000 x 3000
Mode 0 allows only for specifying a region of interest, and does not perform any binning.
Frame rate does not increase when ROI size is reduced. Global Reset is available if using Standard Trigger Mode. This mode is consistent with mode 10 of the FL3-U3-88S2C.
Mode 4 Mode 4 implements a combination of 2X horizontal and 2X vertical binning.
Both horizontal and vertical binning are performed on the sensor, prior to color processing.
On sensor binning is averaged and therefore there is no increase in brightness but there is an increase in frame rate.
On sensor 2x2 binning of the mode 10 resolution (4096 x 2160) resulting in a resolution of 2048 x 1080, consistent with mode 4 of the FL3-U3-88S2C.
Mode 10 Resolution: 4000 x 3000
Mode 10 allows a maximum image size of 4000 x 3000 (12 MP) with a maximum frame rate of 15 FPS.
There is no pixel correction in mode 10. Only 8-bit and 12-bit pixel formats support 12 MP; 16-bit pixel formats support 11 MP and 24-bit pixel formats support 7.4 MP.
Resolution: 4096 x 2160
4k/2k imaging mode.
This mode is consistent with mode 0 of the FL3-U3-88S2C.
