This section compares various lenses used with Elphel 333 Camera and 3MPix sensor.

- computar Lens

- Fujinon Lens ref DF6HA-1B 1:1 2/6mm (spec)

 Picture : view of Strasbourg France [2]
 Picture : second view (minimum aperture) [3]
 Picture : near object and maximum zoom. There is 3 pictures, each with focus on different object
   - picture focus on paper [4]
   - picture focus on water [5]
   - picture focus on USBKey [6]
focus seting is very sensitive. distance between lens and objects 1 meter.

Movie of country with Adapter for Canon Lens , Elphel 333. 3MPix [7]

This not an industrial adaptor, but only a first good experience. Quality of image may be better if we include a manual iris to have more depth in the picture.

5MPix micron sensor

Examples of Electronic Rolling Shutter Distortion

A picture that was made from Elphel's Motor Office moving at approximately 40 mph. [8]

As in 5MPix resolution we have 1/15 second delay from the top to the bottom of the image everything is distorted. Everything but our reflection :)

One more example of distortion inducted by ERS: [9]

Some info on what is ERS and what we intend to do to compensate this artifact.

Gated Intensified

This picture was made by the Elphel 303 camera model. This camera is no longer produced but we plan to do another Gated intensified camera based on Elphel 353. More info on Linux devices.

MJP4 video codec

This is a 5 MPix MJP4/MOV example: [57]. MJP4 is based on JPEG compression of the raw Bayer pixels, rearranged in each macroblock before compression to reduce the high frequency components caused by color )

Endoscopy camera

These videos were made by a prototype endoscopy camera based on Elphel 333. The test was performed in complete darkness with a halogen lamp of 80 Watt. In the black and white video you can see the resolution and in the color one the colors through the endoscope.

At that moment the auto exposure in Elphel 333 was not stable enough to stabilize quickly and was not usable on humans for a real operation. We will soon make same tests with a Elphel 353 camera model.
