Order Options
The camera module can be ordered with an M12 or C/CS mount holder. Lens mounting is also possible.
For dimensions of the holder, please refer to L-867Be.A4 phyCAM Digital Camera Modules Concept and Design-In Guide.
The phyCAM Concept
The phyCAM series of camera modules allows microcontroller designs to be easily and efficiently equipped with image processing technology.
Camera modules with a phyCAM interface can be directly connected to the digital camera interface of selected PHYTEC microcontroller modules. This allows easy integration of camera technology into compact, project-specific products. Many BSPs (Board Support Packages) of PHYTEC microcontroller modules already include the corresponding software drivers for the phyCAM modules.
Due to the open interface definition, phyCAM modules can also be used together with other microcontrollers or hardware designs that have a corresponding camera interface.
The interfaces of the phyCAM products are identical within the respective product series. This makes it possible to connect different camera modules with the same application circuit. This enables scalability during the design phase and in future design variants.
Evaluation kits are available for use during the development phase.
Notes
Further information on the phyCAM concept and important notes on the design-in can be found in document L-867Be.A4 phyCAM Digital Camera Modules Concept and Design-In Guide.
Information on the software integration of the camera modules can be found in document L-867Ae.A0 Quickstart Guide Start-Up phyCAM with Embedded Imaging Kit.
We recommend that you read these two documents before integrating the camera module.
VM-020 Camera Modules Function Overview
On-Board Clock Generation
The master clock (MCLK) for the camera sensor is generated with a 27 MHz oscillator on the camera module. The internal PLL of the camera sensor generates the required operating frequency of the sensor.
This means that it is not necessary to generate the master clock externally and to route it to the camera module.
Further information can be found in the datasheet of the sensor.
On-Board EEPROM
The camera modules are equipped with a 2 kB EEPROM (M24C02-R or compatible). It can be used, for example, to store individual configurations or an identification number.
The EEPROM addressing can be done individually by solder jumpers. The addressing is described in detail in the corresponding sections "I²C addresses" of the individual interface variants.
Further information can be found in the datasheet of the EEPROM.
Trigger / Strobe Connector
The TRIGGER_IN and STROBE_OUT signals can be used for precise timing control, lighting control, or synchronizing multiple cameras.
Pin | Dir | Funktion |
1 | I | TRIGGER_IN |
2 | - | GND (Signalmasse) |
3 | O | STROBE_OUT |
Connector Type | JST BM03B-SRSS-TB |
Suitable Connector Housing | JST SHR-03V-S |
Note
The extension connector signals are also available on the phyCAM-M interface connector. See section "Feature Pins" in the respective descriptions.
Trigger
The trigger input provides the following function:
- In the slave mode of the sensor, the time of image acquisition is controlled. A high level at the trigger input triggers image acquisition.
Details on triggering can be found in the datasheet of the camera sensor.
Strobe
The strobe output provides the following function:
- Output at a high level during the exposure time of the image sensor.
For details on the strobe signal, refer to the datasheet of the camera sensor.
Image Sensor AR0144
The camera module is equipped with an AR0234CS image sensor from ON Semiconductor. The sensor has a resolution of 1920 (H) x 1200 (V) = 2.3 MPixels with a sensor format of 1/2.6".
The image sensor is equipped with a global shutter and is available in a monochrome version or with a Bayer Pattern color mask. Due to the phyCAM concept, the special functions of the sensor are available on almost all interface variants. Further information on the individual functions of the sensor can be found in the manufacturer's datasheet.
Spectral Characteristics
Note
Please refer to the camera sensor data sheet for detailed technical data. At the time of writing this document, the information is confidential and can only be accessed via NDA with ON Semiconductor.
Variable Resolution
The camera sensor of the VM-020 - like other phyCAM modules - allows for the reduction of the effective image resolution by different methods. This allows image details and the amount of data generated to be optimally adapted to the requirements of the application. The frame rate can also be increased by reducing the resolution.
Depending on the desired resolution and requirements of the application, various methods can be used to reduce the resolution:
- Windowing/cropping/ROI:
The image is only read from a part of the sensor Region of Interest (ROI). Pixels outside this field are skipped. This method reduces the effective size of the image window on the sensor, which must be taken into account when calculating the optics. The beginning of the image window can be shifted on the physical sensor, allowing electronic panning. - binning:
In binning, neighboring pixels are combined. This increases the effective size of a pixel and the light sensitivity increases. With color sensors, it should be noted that directly adjacent pixels are not combined, but the next pixels of the same color (see sensor datasheet). - skipping:
When reading, pixels are skipped. The effective sensor area is therefore not reduced or only slightly reduced when the resolution is reduced. This may be useful when calculating the optics or when switching between different modes (electronic zoom).
Embedded Statistics
In addition to the image information, two further lines can be output with statistical data of the image.
Further information can be found in the datasheet of the sensor.
Lens Shading Correction
An algorithm for correcting lens shading is integrated into the sensor.
Further information can be found in the datasheet of the sensor.
DPCM Compression
The DPCM (differential pulse code modulation) method is available for compression from 10 to 8 bits.This procedure is intended to minimize processing power and memory size requirements.
See the sensor datasheet for more information.
Liquid Lens Connector
A liquid lens can be connected directly to the camera board using the optional liquid lens connector.Together with the connector, a Supertex inc. HV892 liquid lens driver is installed on the camera board.The driver or lens is then controlled via the I2C bus of the phyCAM-M interface.For details on configuring the driver chip, please refer to the HV892 datasheet.If this feature is required, please contact our sales department. In the standard configuration these components are not included.
