5 Camera Controls
This section describes the parameters available for the DMK 33UX264 camera. The actual name of the parameter depends on the driver technology used to access the
camera. Parameter names are listed for the three most common ways to access the cameras:
·
USB3 Vision (cross platform, via 3rd party driver)
·
UVC/V4L2 (on Linux, via uvcvideo)
·
IC Imaging Control (on Windows, via Device Driver for The Imaging Source USB 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 way the pixel format is controlled varies significantly among the driver technology used to access the camera:
·
When using USB3 Vision, the pixel format is controlled through the PixelFormat GenICam feature.
·
When using the uvcvideo driver on Linux, the pixel format is defied by video4linux2.
·
When using IC Imaging Control, the pixel format is part of the video format - a parameter which combines pixel format, resolution and readout mode. For more information, refer to the IC Imaging Control documentation sections on VideoFormat and VideoFormatDesc.
The DMK 33UX264 monochrome camera supports multiple pixel formats with variable bits-per-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 Monochrome
This format transmits data using one byte for each pixel.
USB3 Vision drivers see this pixel format as Mono8, while UVC drivers see it with the FourCC Y800.
Page 14
DMK 33UX264 Technical Reference Manual

Camera Controls
The Device Driver for The Imaging Source USB Cameras offers this pixel format as the Y800 video format.
5.1.1.2
16-Bit Monochrome
The sensor of the DMK 33UX264 camera is not capable of providing 16-bit data output. Instead, the pixel data is transmitted in the most significant bits which allows application programs to ignore the sensor-specific data type, and treat the data as if the sensor outputs 16 bits.
USB3 Vision drivers see this pixel format as Mono16, while UVC drivers see it with the FourCC Y16.
The Device Driver for The Imaging Source USB Cameras offers this pixel format as the
Y16 video format.
5.1.2
Resolution
The DMK 33UX264 allows the user to specify which rectangular region of the image sensor to read out during camera operation. The size of this rectangle determines the number of pixels that have to be transferred for each frame and has a significant influence on the required USB 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 USB3 Vision, the resolution is controlled through the GenICam features Width and Height.
·
When using the uvcvideo on Linux, the resolution is selected from a list of fixed formats. Dynamic frame sizes are not available.
·
When using IC Imaging Control, the resolution is part of the video format, a parameter that combines pixel format, resolution and readout mode. For more information, refer to the IC Imaging Control documentation sections on VideoFormat and VideoFormatDesc.

Readout Modes
The DMK 33UX264 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 of view 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 driver technology is used to access the camera:
·
When using USB3 Vision, the resolution is controlled through the GenICam features
DecimationHorizontal, DecimationVertical, BinningHorizontal and BinningVertical.
·
Selecting readout modes is currently not supported through UVC in Linux.
·
When using IC Imaging Control, the readout mode is part of the video format - a parameter that which combines pixel format, resolution and readout mode. For more information, refer to the IC Imaging Control documentation sections on VideoFormat and VideoFormatDesc.
The following readout modes are supported:
·
Default
·
Skipping 2X
·
Skipping 2X vertical
·
Skipping 2X horizontal

5.1.4
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 is used to access the camera:

Camera Controls
·
When using USB3 Vision, the frame rate is controlled through the GenICam feature AcquisitionFrameRate.
·
When using uvcvideo on Linux, the frame rate is selected from a list of available frame rates.
·
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 on other camera settings such as pixel format, resolution and readout modes.

Automatic Exposure and Gain Control
The DMK 33UX264 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 for automatic functions which enables fine-grained control over the image area for that the image parameters are optimized. A selection of pre-defined area presets is available, but the user can also specify the coordinates of a custom 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 that movements 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.

Trigger Timing Parameters
The 33U series camera series offers several options for dealing with bad trigger signals. By using the Debounce Time, Denoise Time and Mask Time parameters, the camera can be configured to ignore pulses on its TRIGGER_IN line under certain conditions.
Useful values for these parameters are application-specific. They depend on the expected trigger frequency, the exposure time and assumptions about the input signal quality.
The default values for all these parameters is 0 µs, assuming perfect signal quality.
5.5.1
Trigger Delay
The Trigger Delay parameter specifies a time for which the camera waits between receiving a trigger signal and starting the exposure of an image. Simulated trigger pulses generated through the Software Trigger function are not delayed by this parameter.

Image Processing
5.8.1
Gamma
The 33U series cameras can perform gamma correction on the image data. If the pixel format of a color camera is set a YUV mode, gamma correction is applied to the Y channel. In bayer raw and RGB24 modes, all color channels are subject to the same gamma correction.

Lookup Table
The 33U 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 is applied 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 to interpolate between the selected entry and one of its neighbors.

Multi-Frame Output Mode
The 33U series cameras support cycling the exposure time through pre-programmed values from frame to frame in order to form a frame set. In post-processing, sets of frames captured with different exposure times can be used to create images with higher dynamic range than those from single exposure.
The camera can be configured to use 2 or 4 different exposure times. If required, different gain values can be selected for use along with the configured
exposure times.
