Tokyo Electronic Industry Co., Ltd. (hereafter called teli) of which the president is Makoto Watanabe developed CSB4000CL, CMOS B/W Camera (Total pixel: 4,190,000). This camera is developed to meet the function required specifically for image processing in a high order originally and have a feature making a clear distinction to previous CCD camera. This camera employs the following features as main function.
This camera employs the following features as main function.

  • Global Shutter: The exposure is performed on all pixels simultaneously.
  • WOI (Window Of Interest): Only arbitrary more than one area can be read out.
  • Multi Slope function: High-dynamic range is achieved.

Camera Link standard is employed to image processing unit and interface to frame grabber board.
As this camera is integrated type and have a small and lightweight body (54 x 43 x 59 mm, approx. 200g), it is suitable for the mount to industrial machine and image processing machine.


Tips and background of development

So far CCD image sensor has been used widely as a device for image input. On the other hand, trend for image processing cameras tend to be required high-pixelization, more speedup and more multifunctionalization. We have responded these needs with technologies of CCD camera such like multiple shutter function, partial scan function and full frame readout. However, due to the structure, CCD image sensor become difficult to respond to the needs of further speedup.
So we developed CMOS image sensor originally to meet the function which is required for image processing and equipped this camera with it.

The principal feature of this CMOS sensor is an electronic shutter mode which permits this camera exposing simultaneously on all pixel at the same timing equal to CCD. The mode adapted to previous CMOS image sensor is called as Rolling shutter or Focal Plane shutter. As the exposure timing of those modes is different at each line, the camera cannot shoot the moving subjects without shaking if you don't use a mechanical shutter. The CMOS image sensor developed in this time can expose all pixel images at the same timing like CCD. As this function wipe out the weak point of previous CMOS image sensor, it make the camera with CMOS image sensor achieve using for image processing.
CMOS can also readout the specific part in exposure area thanks to the structure. WOI (Widow Of Interest) makes full use of this function. As unnecessary area is not needed to readout, the speedup of readout can be achieved. In reference to the various use for image processing. WOI can be designated the areas up to 16.

Main application

  • For image processing (for manufacturing machine, detection machine, etc.)
  • ITS application for readout of the car number.
  • Readout of bar cords and two-dimensional cord.
  • For micro scope

Features

  • Adoption of CMOS sensor (Total pixel: 4,190,000)

    In this camera, as a square-grid-array and CMOS image sensor are integrated to achieve high resolution.
  • WOI (Widow Of Interest)

    Speedup of image processing can be achieved by readout the arbitrary more than one area designated by user.
  • Global shutter

    The exposure of all pixels at the same timing and easy capturing the stationary images are available.
  • Multi Slope function

    High-dynamic range can be achieved by compression the light and dark on CMOS sensor's own. You can set the original value other than preset value and use them with external selection.
  • Camera Link I/F

    This camera adopts Camera Link Interface for connection of Frame grabber board.
  • C-mount

    This camera employs C-mount as a general standard for industrial camera. TFL2520 is also available as a recommendation lens taking full advantage of high resolution (4,190,000 pixels) to the four corners of the display.
  • Small and lightweight body suitable for mounting to the unit.

    This model is integrated type having small and lightweight body (54 x 43 x 59mm, approx. 200g). As this camera has a DC12V driving, it is suitable for mounting into equipments.
