Negative gain
The BVS CA-GX cameras use a minimum needed basic gain for typical sensor output signals to get near the maximum ADC (analog-to-digital converter) saturation limit (Figure 3). This guarantees a higher sensitivity. However, to take advantage of the whole ADC range of the sensor, you can use "negative gain". Together with enough illumination, you can get a better signal-to-noise ratio given that this setting will affect the analog signal before it is processed by the ADC.
- Note
- Depending on the value of the adjusted negative gain, it can be possible that single pixels pass over their signal limits. In the live image, you will have the effect that some pixels do not change their behavior and the whole image seems to be "frozen".
Output sequence of color sensors (RGB Bayer)
Bilinear interpolation of color sensors (RGB Bayer)
For Bayer demosaicing in the camera, we use bilinear interpolation:
-
Interpolation of green pixels: the average of the upper, lower, left and right pixel values is assigned as the G value of the interpolated pixel.
For example:(G3+G7+G9+G13) G8 = -------------- 4
For G7:(G1+G3+G11+G13) G7_new = 0.5 * G7 + 0.5 * --------------- 4 -
Interpolation of red/blue pixels:
Interpolation of a red/blue pixel at a green position: the average of two adjacent pixel values in corresponding color is assigned to the interpolated pixel.
For example:(B6+B8) (R2+R12) B7 = ------- ; R7 = -------- 2 2
Interpolation of a red/blue pixel at a blue/red position: the average of four adjacent diagonal pixel values is assigned to the interpolated pixel.
For example:(R2+R4+R12+R14) (B6+B8+B16+B18) R8 = --------------- ; B12 = --------------- 4 4
Any colored edge which might appear is due to Bayer false color artifacts.
- Note
- There are more advanced and adaptive methods (like edge sensitive ones) available if the host is doing this debayering.
Supported image formats
It depends on the sensor model which image formats are actually supported.
The parameter PixelFormat in the ImageFormatControl lists all the supported image formats of the specific camera model. In ImpactControlCenter you can find the PixelFormat parameter in "Setting → Base → Camera → GenICam → Image Format Control → Pixel Format".
