Images

3MPix micron sensor

Examples of various lens

This part compare various lens with sensor 3Mpix and 333 Elphel Camera.

- computar Lens

- Fujinon Lens ref DF6HA-1B 1:1 2/6mm [1]

 picture are make with follow command : http://IP/admin-bin/ccam.cgi?opt=\*cvhxy\&sens=4\&e=10000\&iq=100

How to build a Canon EOS Lens adatator for Elphel 333

- Canon EOS Lens with adaptator [2] [3]

A heasy way to build a C adaptator for Canon EOS Lens [4].

Take a protection of lens, make a central holl and fixe two C/CS adaptators [5] to avec a good focal distance.

We have tested various Canon Lens that professional reporter lend me. [6]

- Canon Lens mounted on 333 : [7] [8]

Pictures result of various lens :

The main of this test is to try to use Canon EOS lens, more reference and less expensive of C Lens. The second gool is to be able to use hight definition of CMOS sensor without optical resolution of C-Lens. canon Eos UMS PRO 17-40 : mount of 333 Elphel [9]

-- view of Strasbourg House (France) [10]

-- second view with another set of Canon Lens (minimum apperture) [11]

-- view of cat and barbie dole [12]

In fact : a canon large vision become a Power Zoom this CMOS size difference. 35mm to 1/2" [13]

Conclusion : image quality is better than C-lens (varifocal computar our fixe-focal Fujinon) but Canon lens become a super Zoom Lens and we not certify thermal stability of adjustment action (focus)

It will be fine to test a fishEyes for Canon.

Expensive projet of Adaptator to use EOS Lens can be find on net [14] or [15]

5MPix micron sensor

Examples of Electronic Rolling Shutter Distortion

A picture what was made from Elphel's Motor Office moving at approximately 40 mph. [16]

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: [17]

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

Nature & animals

Humming birds: [18] [19]

Other

The logo from Elphel's Motor Office mirrored in a window. [22]

11MPix kodak sensor

Just images, nothing special [23], [24], [25]

Gated Intensified

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

High FPS

Slow motion fire show. This is a 512x384 resolution, 138 fps video done with an Elphel 333 camera with a 3 MPix sensor with out IR-cut filter. Exposure time was 4ms: [29]

Sport application

100 FPS with timestamps watermarked
