5 Camera Controls
This section describes the parameters available for the DMK 33UX183 camera. The actual name of the parameter depends on the driver technology used to access the
camera. Parameter names are listed for the 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 33U, 37U and 38U 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 33UX183 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.

8-Bit Monochrome
This format transmits data using one byte for each pixel. USB3 Vision drivers see this pixel format as Mono8.
Page 14
DMK 33UX183 Technical Reference Manual
14
Camera Controls
UVC drivers see it with the FourCC Y800. The Device Driver for The Imaging Source USB 33U, 37U and 38U Cameras offers this
pixel format as the Y800 video format.
5.1.1.2
12-Bit Packed Monochrome
This format transmits data using 3 bytes for each pair of 2 consecutive pixels. USB3 Vision drivers see this pixel format as Mono12p. UVC drivers see it with the FourCC Y12p. The Device Driver for The Imaging Source USB 33U, 37U and 38U Cameras offers this
pixel format as the Y16 video format. Since the DMK 33UX183 camera offers both 12­bit packed and 16-bit monochrome pixel formats, the driver will use the 12-bit packed format when the Y16 video format is selected.
5.1.1.3
16-Bit Monochrome
The sensor of the DMK 33UX183 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. UVC drivers see it with the FourCC Y16. The Device Driver for The Imaging Source USB 33U, 37U and 38U Cameras offers this
pixel format as the Y16 video format.
5.1.2
Resolution
The DMK 33UX183 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

Readout Modes
The DMK 33UX183 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 readout mode 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:

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:
·
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 upon other camera settings such as well, pixel format, resolution and readout modes.

Automatic Exposure and Gain Control
The DMK 33UX183 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. Specifying a region of interest enables fine-grained control over the 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 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 Operation
The Trigger Operation parameter controls the operation mode of the sensor in trigger mode.
Rolling shutter sensors can use the Global Reset Release mode when being triggered. In this mode, the integration time starts simultaneously for all lines. At the end of the nominal exposure time, the sensor then stops integrating and starts reading out the lines - as it is typical for a rolling shutter. Therefore, every line has a slightly longer actual exposure time than the line above it.

Digital I/O
The 33U series has one digital input and one digital output. The digital input can be used as a Trigger input but the current status can also examined directly.
The digital output can be configured as a Strobe output to signal the exact moment when the image sensor is sensitive to light so that external light sources can be synchronized to its operation cycle.

Image Processing

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.

5.8.2
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.
The LUT Enable feature enables the lookup table.
Parameter
LUT Enable
True
Enable lookup table operation
False
Disable lookup table operation

The lookup table values can be programmed using the LUT Index and LUT Value features.

Important: Since gamma correction is implemented using the same hardware as the lookup table, gamma correction is disabled when the lookup table is enabled.
