Sensor, pixel clock
Changes on the capturing parameters (such as exposure or gain) only have an effect on the
image after the next which is caused by the sensor. This is independent of the operating mode.
The pixel clock can only be adjusted in steps. The steps get bigger with higher values.
The adjustable pixel clock changes between 8/10 bit and 12 bit.
Note the bandwidth requirement for bit depth greater than 8 bits per pixel.
It is recommended to use packed color formats in 10 bit mode with high pixel clocks.
If the camera is operated without image memory there are additional pixel clocks in 10 MHz
steps. The image quality may be reduced in the lower image area because of the slow reading-
out. It is recommended to operate the camera with image memory in case of bandwidth
problems or in multi-camera operation.
AOI
The sensor speed does not increase by the use of a horizontal AOI.
Frame rate
In 10 bit mode, the sensor will not get faster than in 8 bit mode.
Binning
The sensor does not support binning.
Subsampling
Subsampling does not increase the frame rate.
Trigger
The internal sensor delay is about 2-3 lines when triggering. The line period depends on the
selected pixel clock. The higher the pixel clock, the smaller the line period is.
Vertical AOI merge mode
For color sensors, the AOI merge mode can only be used with at least 2 lines.
