Notes on using the UI-122x / UI-522x
· Optimum pixel clock frequency is 27 MHz.
· The color version has no hardware gain controls. The driver simulates these.
· The RGB gain controls have no effect in raw Bayer mode.
· Sensor speed does not increase for AOI width <608 pixels (constant image height).
· The sensor binning works by averaging pixels, so the image will not become brighter
when binning is activated.
· The frame rate is not significantly higher with horizontal 4x binning than with 2x binning.
· Extreme overexposure may shift the black level. As an effect, the white level is no longer
reached.
· Functions that modify image content (such as exposure or gain) are applied with a delay
of one frame time. This is also the case in trigger mode.
· IR illumination with 900 nm causes blooming.
· With horizontal 4x binning, a dark column appears at the right-hand image border, which
is caused by the sensor.
· For sensor reasons, the (black level) offset cannot be modified when HDR mode is
active.
· Master gain and gain boost should be disabled when using HDR mode.
