Description of the data path Sensor The GUPPY cameras are equipped with various sensor types and resolutions. Both CCD and CMOS types are available in monochrome (B) and color (C). The following table provides an overview: Model Techn. Manu- Sensor Optical Diag.
Horizontal and vertical mirror function (only Guppy F-036) The Guppy F-036 CMOS cameras are equipped with a horizontal and verticaql mirror function, which is built directly into the sensor. The mirror is centered to the actual FOV center and can be combined with all image manipulation functions, like binning.

Voltage (Reg0x48 or result of BLC) Figure 33: Signal path of MT9V022 (Guppy with CMOS sensor) In CMOS cameras offset and gain are in reversed order compared to the CCD cameras. Therefore the offset is also amplified. So after changing gain, white balance may also be changed.

Automatic white balance can also be enabled by using an external trigger. However, if there is a pause of >10 seconds between capturing individual frames this process is aborted. The following flow diagram illustrates the automatic white balance sequence. GUPPY Technical Manual V4.0.1...
This allows for the positioning of the work area to be at the bottom of the active image. Another case is for outdoor applications: the sky will be excluded from the generation of the reference levels when the autofunction AOI is placed at the bottom of the image. GUPPY Technical Manual V4.0.1...

• Auto gain of CMOS models is directly controlled by the CMOS sensor (the target grey level is fixed to 125). Changes to this register have no effect in conjunction with auto gain. Auto exposure is working in conjunc- tion with auto shutter only. GUPPY Technical Manual V4.0.1...
Increments are in 8/25 LSB Note • Setting the gain does not change the offset (black value) for CCD models. The IIDC register brightness at offset 800h is used for this purpose. The following table shows the BRIGHTNESS register. GUPPY Technical Manual V4.0.1...
Increasing the auto exposure value increases the average brightness in the image and vice versa. The applied algorithm uses a proportional plus integral controller (PI control- ler) to achieve minimum delay with minimum overshot. GUPPY Technical Manual V4.0.1...

When both auto shutter and auto gain are enabled, priority is given to increasing shutter when brightness decreases. This is done to achieve the best image quality with lowest noise.

Description of the data path Look-up table (LUT) and gamma function The AVT GUPPY camera provides one user-defined look-up table (LUT). The use of this LUT allows any function (in the form Output = F(Input)) to be stored in the camera's RAM and applied to the individual pixels of an image at run-time.

2 x and 4 x binning Binning is the process of combining neighboring pixels while being read out from the CCD chip. GUPPY F-036 b/w cameras have this feature.

Description of the data path HDR (high dynamic range) (GUPPY F-036 only) The HDR mode is available for the GUPPY F-036 cameras with the Micron MT9V022 sensor. (HDR = high dynamic range) Advanced registers for high dynamic range mode (HDR) (GUPPY F-036 only) The GUPPY F-036 cameras offer the so-called high dynamic range mode (HDR mode) with one or two knee points.
The color sensors capture the color information via so called primary color (R-G-B) filters placed over the individual pixels in a BAYER mosaic layout. Guppy color cameras have no color interpolation, so the BAYER demosaicing has to be done outside the camera in the PC (raw mode).
Description of the data path Serial interface All GUPPY cameras are equipped with the SIO (serial input/output) feature as described in IIDC V1.31. This means that the GUPPYs serial interface which is used for firmware upgrades can also be used as a general RS232 interface.

Table 97: Time base ID on page 193). The default value here is set to 20 µs. Exposure time of CMOS sensor (GUPPY F-036) The CMOS sensor of GUPPY F-036 enables shutter times in integer multiples of the row time (29.89 µs). Note Although you can enter shutter register values as usual, the camera will round down to integer multiples of the row time.
The minimum adjustable exposure time set by register is 20 µs. The real minimum exposure time of GUPPY F-033 is then 20 µs + 24.28 µs = 44.28 µs. Extended shutter The exposure time for long-term integration of up to 67 seconds for the CCD- models and up to 979 ms for the CMOS models can be extended via the EXTENDED_SHUTTER register.
