Camera Controls
This section describes the parameters available for the DFK 39GX265-Z20 camera.
The actual name of the parameter depends on the driver technology used to access thecamera. Parameter names are listed for the most common ways to access the cameras:· GigE Vision (cross platform, via 3rd party driver)· IC Imaging Control (on Windows, via Device Driver for The Imaging Source GigE

Cameras)5.1

Sensor Readout Control

5.1.1

Pixel Format
The pixel format defines the data type of the pixels transmitted to the computer. The
bits per pixel needed for a particular pixel format influence the required bandwith.
The driver technology used to access the camera significantly impacts the way the pixel
format is controlled:· When using GigE Vision, the pixel format is controlled through the PixelFormat

GenICam feature.
· When using IC Imaging Control, the pixel format is part of the video format - aparameter which combines pixel format, resolution and readout mode. For more
information, refer to the IC Imaging Control documentation sections on
VideoFormat and VideoFormatDesc.
The DFK 39GX265-Z20 color camera supports multiple pixel formats with variable bitsper-pixel settings. The names of the pixel formats and the way to select them depends
on the driver used to control the camera. The following table contains a short overview
of all possible formats followed by a more detailed description.

5.1.1.1

8-Bit Bayer Raw
This format transmits data using one byte for each pixel.
GigE Vision drivers see this pixel format as one of the 8-bit bayer raw formats(BayerGR8, BayerRG8, BayerGB8, BayerBG8).
The Device Driver for The Imaging Source GigE Cameras simplifies this variety of possible
pixel formats and offers two video formats instead: RGB32 and Y800. The RGB32
format results from the driver's automatic debayering of the raw image data, while theY800 format contains the raw data which is reinterpreted as monochrome.

5.1.1.2

12-Bit Packed Bayer Raw
This format transmits data using 3 bytes for each pair of 2 consecutive pixels.
GigE Vision drivers see this pixel format as one of the 12-bit packed bayer raw formats(BayerGR12Packed, BayerRG12Packed, BayerGB12Packed, BayerBG12Packed).
The Device Driver for The Imaging Source GigE Cameras simplifies this variety of possible
pixel formats and offers two video formats instead: RGB64 and Y16. The RGB64 format
results from the driver's automatic debayering of the raw image data, while the Y16
format contains the raw data which is reinterpreted as monochrome. Since the DFK
39GX265-Z20 camera offers both 12-bit packed and 16-bit bayer raw pixel formats, thedriver uses the 12-bit packed format when the RGB64 or Y16 video format is selected.

5.1.1.3

16-Bit Bayer Raw
This format transmits data using 2 bytes for each pixel.
The sensor of the DFK 39GX265-Z20 camera is not able to provide 16-bit data output.
The pixel data is transmitted in the most significant bits. This allows application
programs to ignore the sensor-specific data type and to treat the data as if the sensor
outputs 16 bits.
GigE Vision drivers see this pixel format as one of the 16-bit packed bayer raw formats(BayerGR16, BayerRG16, BayerGB16, BayerBG16).
The Device Driver for The Imaging Source GigE Cameras simplifies this variety of possible
pixel formats and offers two video formats instead: RGB64 and Y16. The RGB64 format
results from the driver's automatic debayering the raw image data, while the Y16
format contains the raw data which is reinterpreted as monochrome.

5.1.1.4

YUV 4:2:2
This format transmits an 8-bit luminance value for every pixel and a pair ofchrominance values for every two pixels.
The camera converts the raw pixel data from the sensor to YUV 4:2:2. Since YUV 4:2:2
averages to 2 bytes per pixel, the YUV 4:2:2 pixel format requires two times the
bandwidth of the 8-bit raw format, thus reducing the maximum possible frame rate.
GigE Vision drivers see this pixel format as YUV422_8.

DFK 39GX265-Z20 Technical Reference Manual13Camera Controls
The Device Driver for The Imaging Source GigE Cameras offers this pixel format as theYUY2 video format.

5.1.1.5

YUV 4:1:1
This format transmits an 8-bit luminance value for every pixel and a pair ofchrominance values for every four pixels.
The two YUV 4:1:1 pixel formats only differ in their byte order.
The camera converts the raw pixel data from the sensor to YUV 4:2:2. Since YUV 4:2:2
averages to 1.5 bytes per pixel, the YUV 4:2:2 pixel format requires two 50% more
bandwidth than the 8-bit raw format, thus reducing the maximum possible frame rate.
GigE Vision drivers see this pixel format as YCbCr411_8 and YCbCr411_8_CbYYCrYY.
The Device Driver for The Imaging Source GigE Cameras offers this pixel format as theY411 video format.

5.1.1.6

RGB24
The camera converts the raw pixel data from the sensor to RGB24. Since RGB24 uses 3
bytes to store 1 pixel, the RGB24 pixel format requires three times the bandwidth of the
8-bit raw format, thus reducing the maximum possible frame rate.
GigE Vision drivers enumerate this pixel format as BGR8.
The Device Driver for The Imaging Source GigE Cameras enumerates this pixel format as
the RGB24 video format.

5.1.2

Resolution
The DFK 39GX265-Z20 allows the user to specify which rectangular region of the image
sensor to read out during camera operation. The size of this rectangle determines thenumber of pixels that have to be transferred for each frame and has a significant
influence on the required network bandwidth.
Lowering the resolution also often allows the image sensor to operate at a higher frame
rate. Changes in the vertical resolution have more effect on the maximum frame rate
than changes in the horizontal direction.
The way the resolution is controlled varies greatly between the driver technology used
to access the camera:· When using GigE Vision, the resolution is controlled through the GenICam features

Width and Height.
· When using IC Imaging Control, the resolution is part of the video format, a parameterthat combines pixel format, resolution and readout mode. For more information, referto the IC Imaging Control documentation sections on VideoFormat andVideoFormatDesc.

HeightReadout Modes
The DFK 39GX265-Z20 camera offers different sensor readout modes.
By default, the camera outputs all pixels of the image sensor.
In skipping modes, the image sensor regularly skips a number of rows and/or columns
during readout. The resulting output image is smaller but contains the same field ofview than the image produced by default readout mode.
In binning modes, a number of neighboring pixels is merged into one output pixel
during readout. The nature of this merge operation is sensor-specific, most sensors
either add the pixel values or average them.
Generally, binning modes provide better image quality than skipping modes. However,skipping modes usually provide a higher maximum frame rate.
The way the readout modes are controlled depends greatly upon which drivertechnology is used to access the camera:· When using GigE Vision, the readout mode is controlled through the GenICam

features DecimationHorizontal, DecimationVertical, BinningHorizontal
and BinningVertical.
· When using IC Imaging Control, the readout mode is part of the video format - aparameter that which combines pixel format, resolution and readout mode. For more
information, refer to the IC Imaging Control documentation sections on

Frame Rate
The frame rate is specified in frames per second and determines the camera's operating
speed.
The way the frame rate is controlled depends greatly upon which driver technology isused to access the camera:· When using GigEVision, the frame rate is controlled through the GenICam feature

AcquisitionFrameRate.
· When using IC Imaging Control, the frame rate is selected from a list of available
frame rates through APIs such as Grabber::setFPS or
ICImagingControl.DeviceFrameRate.
The range of available frame rates depends upon other camera settings such as well,

Automatic Exposure and Gain Control
The DFK 39GX265-Z20 camera can automatically control gain and exposure time. These
automatic functions are enabled by default.
In order to optimize image parameters, a region of interest can be specified forautomatic functions. Specifying a region of interest enables fine-grained control overthe image area for which the image parameters are optimized. A selection of predefined area presets is available, but the user can also specify the coordinates of acustom rectangle.
In certain situations, it is desirable to limit the range of the auto-controlled parameters.
For example, one might want to avoid high gain settings in order to keep noise levels
low. Other applications require limiting the maximum exposure time so thatmovements do not get blurred. Therefore, the ranges of the gain and exposure
parameter can be limited.
If both auto exposure and auto gain are active, the camera tries to lower the gain value
in order to reduce noise and improve the image quality.

White Balance Mode
The default auto white balance algorithm is Gray World. It is selected by setting theWhite Balance Mode accordingly. The Gray World algorithm operates under theassumption that the average color of a scene is near gray and adjusts the white balancecoefficients so the average color of the resulting image is gray as well. In the casewhere this assumption is wrong (e.g. the camera is pointing at a blue carpet), the auto
white balance algorithm will select coefficients that do not result in a visually accurate
image.
To avoid the problems posed by the Gray World algorithm, the Temperature mode canbe used. This mode operates by trying to determine the color temperature of the lightsource.

Gamma
The 39G series cameras can perform gamma correction on the image data. If the pixel

Lookup Table
The 39G series allows the user to specify a lookup table (LUT) that can transform pixel
values. This lookup table can be used to perform tasks like histogram equalization
inside the camera.
If the pixel format of a color camera is set to one of the YUV modes, the lookup table isapplied only to the Y channel. In bayer raw and RGB24 modes, all color channels are
subject to the same lookup operation.
The lookup table has 257 16-bit entries. The upper 8 bits of the image data are used to
select the appropriate entry in the lookup table, while the remaining bits are used tointerpolate between the selected entry and one of its neighbors.
The LUT Enable feature enables the lookup table.
