Sensor, pixel clock, gain
• | The color version has no hardware gain controls. The driver simulates these. |
• | The RGB gain controls have no effect in raw Bayer mode. |
• | Sensor brightness control: The sensor does not use the average image brightness value as the actual value for brightness control. Instead, it uses a value calculated internally from the histogram. This value is defined with 12% of the pixels being brighter than the actual value. |
• | Sensor brightness control: The permissible value range for the reference value is [44...235]. You cannot set any smaller values (down to black = 0) or higher values (up to white = 255). |
• | 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. |
• | The hardware gamma function uses the sensor's companding mode with a piecewise linear characteristic. When using RGB gains on the color version of the camera, hardware gamma may lead to a non-linear color representation. |
Binning, AOI, HDR 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. |
• | 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. |
