The Imaging Source DBK 21AU04.AS

Fast display of colour images

The raw data (8 bit/pixel, RAW format) from the colour CCDs require some post-processing. This is taken care of in the colour interpolation process: Raw data is converted into one of many commonly used colour formats. This requires at least 16 bits per pixel and thus, broader bandwidth during transfer. Colour interpolation in the astro CCD camera DBK 21AU04.AS can be switched off, thus 60 colour images per second can be transfered. Colour interpolation can then be carried out on the host PC, with the shipped software IC Capture.AS. Alternatively, should colour interpolation not be desirable at all, AVI files can be written in RAW format.

Sony® colour CCD

The CCD camera DBK 21AU04.AS deploys the Sony® colour CCD ICX098BQ. The format of this CCD is 1/4". The chip outputs data using progressive scan at a resolution of 640 x 480 pixels. Even at long exposure times, its noise is minimal. Thanks to the high quality of this CCD, it is often deployed in medical image processing applications.

No IR cut filter

Although the astro CCD camera DBK 21AU04.AS has a color CCD, it does not have an IR cut filter. It is therefore possible that users of this astro CCD camera can fit their own filters, thus being able to set it up to their own requirements.

Fast data transfer via USB 2.0

The astro CCD camera DBK 21AU04.AS outputs uncompressed colour images in fast sequences. In order to transfer these to the host PC, a very fast bus is required. Hence, the camera is fitted with a USB 2.0 connector.

Shipped software for Windows®

This camera ships with the camera driver and the control software IC Capture.AS.
