phyCAM-L VM-016 1/4“ 1 MPixel Camera Module

Overview

The VM-016 camera modules are equipped with the AR0144 CMOS sensor from ON Semiconductor.

All variants have an EEPROM (2 kB), an on-board clock generation as well as an expansion connector for synchronization of the image acquisition (trigger/strobe).

PHYTEC offers the VM-016 camera modules with the following interfaces/product series:

  • phyCAM-P
  • phyCAM-S+
  • phyCAM-M
  • phyCAM-L

Please use the correct manual for the interface you have.

phyCAM Concept

The phyCAM series of camera modules allow for the easy and efficient configuration of microcontroller designs with image processing technology.

Camera modules with phyCAM interface can be directly connected to the digital camera interface of selected PHYTEC microcontroller modules. This allows for easy integration of camera technology into compact, project-specific designed products. Many BSPs (Board Support Packages) of PHYTEC microcontroller modules already contain 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 and allows scalability during the design phase and in future design variants.

Evaluation kits are available for the development phase.

Note

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 considering the information in these two documents before integrating the camera module.

Function Overview VM-016-L Camera Modules

FPD-Link III

The FPD-Link III works with the DS90UB953 from TI. More information can be found in the datasheet of the serializer.

Power-Over-Coax

The camera module power supply is supplied via Power-Over-Coax. The module does not require any further voltage source.

On-board Clock Generation

The master clock (MCLK) for the camera sensor is generated via the FPD-Link III and can be configured here. The internal PLL of the camera sensor is then used to generate the required operating frequency of the sensor.

Further information can be found in the sensor's datasheet or the FPD-Link III serial description combination.

On-Board EEPROM

The camera modules are equipped with a 2 kB EEPROM (M24C02 or compatible). It can be used, for example, to store individual configurations or an identification number.

The addressing of the EEPROM can be done individually by a solder jumper. The addressing is described in more detail in the corresponding sections under the I2C Address of the individual interface variants.

Further information can be found in the datasheet of the EEPROM.

Trigger/Strobe Extension Connector

The TRIGGER_IN and STROBE_OUT signals can be used for precise timing of recording, lighting control, or synchronizing multiple cameras.

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.

Expansion Connector (optional)

Using the optional Expansion Connector, it is possible, for example, to implement additional features (lighting, autofocus, etc.) directly on the camera.

The maximum current flow and power consumption at Vcam must not exceed the maximum permissible current flow and power via the PoC connection.
Care must be taken to keep the total ripple/noise as low as possible.
The minimum supply voltage must be increased by the amount of the DCR losses if additional power is used via the expansion connector.
See L-867Be.A4 phyCAM Digital Camera Modules Concept and Design-In Guide.

Image Sensor AR0144

The camera module is equipped with an AR0144CS image sensor from ON Semiconductor. The sensor has a resolution of 1280 (H) x 800 (V) = 1.0 MPixels with a sensor format of 1/4".

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 Sensitivity

Note

For detailed technical data, please refer to the datasheet of the camera sensor. At the time of writing this document, the information is subject to confidentiality and can only be viewed by means of an NDA with ON Semiconductor.

Variable Resolution

The camera sensor of the VM-016 - 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. Therefore, the effective sensor area is 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.

A-Law Compression

To improve the signal-to-noise ratio, quantization of the analog pixel information with the A characteristic can be performed in the sensor.

Further information can be found in the datasheet of the sensor.

SBC Kits

Single Board Computer (SBC) kits are available for various microprocessor platforms and operating systems for testing camera modules as well as application development. PHYTEC is continuously expanding the platforms supported in these kits. Please refer to www.phytec.de for the latest information on available kits. Our sales and support team is ready to assist in the selection of the appropriate kits and image processing hardware.
