Open Source Digital Cinema Camera from Elphel.

Technical Specs:

Sensor:

The camera uses an Aptina CMOS bayer-pattern sensor with an optical format of 1/2.5″ (5.70mm x 4.28mm) and a native resolution of 2592×1944 (5 Megapixels). It features a 12 bit ADC and supports: region of interest, on-chip binning and decimation. Aptina claims that the chip has 70db of dynamic range at full resolution and 76db when using 2×2 binning.

Lens Mount:

The camera has a standard C-mount but ships with an adapter ring that allows to mount CS-lenses as well. More adapters are in planning stage.

Resolutions:

The recording resolution can be freely adjusted to anything starting from 16×16 to 2592×1944 in 16 pixel steps. This includes Apertus AMAX (2224×1251), Apertus CIMAX (2592×1120), 2K (2048 × 1536), Full HD (1920×1080), HD (1280×720) and of course all lower resolution SD formats like DV PAL, DV NTSC, etc.

The lower the resolution the higher the maximal possible framerate. At the full sensor size (5 million pixels or 5 Megapixels) the maximal frame rate is 10 fps in normal color mode and 15 fps in JP4 RAW mode. JP4 achieves higher framerates in general as some camera internal calculations are skipped and need to be applied later in postproduction (like debayering/demosaicing).

Raw Recording:

The RAW recording mode in Apertus is called JP4 RAW. Because certain in-camera compression steps can be skipped JP4 RAW allows higher recording speed resulting in more fps. JP4 RAW requires postprocessing (DNG Converter) but in return offers the highest possible image quality.

Connectors:

SATA: Can be used to connect any external SATA device that is supported under Linux (external harddrives, raids, etc.)

Ethernet: 100MBit Network with POE (48V)

USB: USB 1.1 with 5V power supply

IDE: Used to connect internal HDD

RS232: Access to Console and debug output

Recording Media:

• Optional internal IDE 1.8″ HDD
• 2 internal CF Card Slots
• external SATA connector to connect any SATA device (Linux support required)
