Extended Depth of Field Cameras

A fusion of RICOH optical design and image processing technology has realized a depth of field 3 to 5 times* better than conventional cameras (compared to RICOH products).

Consisting of a dedicated camera equipped with a newly developed special algorithm and a specific range of lenses, RICOH’s extended depth of field camera system requires no focus readjustment or no repositioning of the camera or subject. A new 5MP high resolution camera with 3 dedicated lenses have been added to the EDoF lineup to support a wider range of applications.

  • *When compared to cameras at the same working distance. The extended depth of field effect varies depending on the subject matter.

image:Ricoh is an expert in optical design technologyand in the image-processing technology used in cameras,which is why we are able to create these new Extended Depth of Field Cameras.

What is RICOH extended depth of field camera?

  • The combination of a dedicated camera utilizing a newly developed special algorithm and a dedicated lens.
  • Available camera resolutions include 5MP (up to 53 fps), 2MP (15 fps) and VGA (90 fps).
  • Uses FPGA (Field Programmable Gate Array) to achieve near real time image data processing.
  • Equipped with an effective [AOI* scan mode] to improve the quality and speed of inspection.
    * Area of Interest: Only the part of the image required for scanning is scanned and transferred, reducing the time required to read and transfer data.

Foreground and background subjects are in focus, so there is no need to readjust the focus or the subject and camera positions.

Substrate visual inspection

With an extended depth of field camera, the entire depth of field is in focus, from the front of the foot of the substrate (indicated by the red arrow) to the back, even in substrate inspections using a high condenser.
