3MPix micron sensor

Examples of pictures taken with various lens types

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 [1]
 take with follow settings : /admin-bin/ccam.cgi?opt=\*cvhxy\&sens=4\&e=10000\&iq=100

- EOS Canon adapter with professional lens 17-40 UMS (photo)

 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.

Nature & animals

Humming birds: [10] [11]

Grand Teton N.P.: [12] [13]

Geo Tagged EXIF

This is an example of Geo Tagged JPEG image from Elphel 353 camera [14] . The Geo Tagging is included inside the EXIF. For more info read GeoTagging page.

The logo from Elphel's Motor Office mirrored in a window. [15]

11MPix kodak sensor

Just images, nothing special [16], [17], [18]

Car license plate in the dark with headlights: [19]

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.

First example done with Elphel 353 camera, 1600x1200: [23]

An example of a 1920x1072 video at 24 FPS done with Elphel 353: [24]

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: [25]

100 FPS cafe :) encoded in 3gp

A 100 FPS video done with Elphel 353 camera at 640x480 resolution. The video was then resized to 320x240 and encoded in 3gp. This file can be played on 3gp compatible mobile mobile phones. [26]

Sport application

100 FPS with timestamps watermarked

Swimming: [27] and the "uncompressed" MJPEG version [28]

Photo finish

Some info about photo finish

Slow motion lighter video

A lighter filmed at 112x112 1038 FPS, the replay is at 24 FPS [29]

High res video

This is an example of 3 MPix mpeg4 video transcoded on the fly by VLC from the standard MJPEG/RTP [30]

This small video of a lizard in 5 MPix resolution and MOV container was recorded to a SATA disk attached directly to the NC353L camera trough 10369 board by camogm : [31]

Examples of Electronic Rolling Shutter Distortion

This HD and 5MPix videos demonstrate the Electronic Rolling Shutter Distortion: [32], [33], [34]. (500 MB videos!)

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

MJP4 video codec

This is a 5 MPix MJP4/MOV example: [51]. 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 )

Medical

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.

1024x768 25fps endoscopy videos:

monochrome [48MB] - [52]
