Figure 4 1 Frame rate in sequential readout mode and simultaneous readout mode Sequential readout mode For the calculation of the frame rate only a single formula applies frames per second equal to the inverse of the sum of exposure time and readout time 31 4 Functionality Simultaneous readout mode exposure time lt readout time The frame rate is given by the readout time Frames per second equal to the inverse of the readout time Simultaneous readout mode exposure time gt readout time The frame rate is given by the exposure time Frames per second equal to the inverse of the exposure time The simultaneous readout mode allows higher frame rate However if the exposure time greatly exceeds the readout time then the effect on the frame rate is neglectable CE Insimultaneous readout mode image output faces minor limitations The overall linear sensor reponse is partially restricted in the lower grey scale region gt When changing readout mode from sequential to simultaneous readout mode or vice versa new settings of the BlackLevelOffset and of the image correction are required Sequential readout By default the camera continuously delivers images as fast as possible Free running mode in the sequential readout mode Exposure time of the next image can only start if the readout time of the current image is finished exposure X read out X exposure X read out Figure 4 2 Timing in free running

8. 4 3 Reduction of Image Size With Photonfocus cameras there are several possibilities to focus on the interesting parts of an image thus reducing the data rate and increasing the frame rate The most commonly used feature is Region of Interest ROI 4 3 1 Region of Interest ROI Some applications do not need full image resolution e g 2080 x 2080 pixels By reducing the image size to a certain region of interest ROI the frame rate can be drastically increased A region of interest can be almost any rectangular window and is specified by its position within the full frame and its width W and height H Table 4 3 presents numerical examples of how the frame rate can be increased by reducing the ROI cs Reductions in y direction result in a higher frame rate Reduction in x direction may result in a higher frame rate as the required data bandwidth is lowered CS The ROI width must be a multiple of 2 zB It is recommended to re adjust the settings of the shading correction each time a new region of interest is selected gt A frame rate calculator for calculating the maximum frame rate is available in the support area of the Photonfocus website 4 3 2 Interface restriction on maximum frame rate The camera can be operated with settings that exceed the maximal available band width of approx 108 MB s on the GigE interface This will result in lost dropped images The maximal data rate for the GigE interface is 8 108 10
