For visualization applications, it does not make sense to view the RAW image stream from the CMOS Pregius chip. It must be interpolated, before it may be viewed or saved in common formats. IC Capture.AS perform color interpolation, thus reducing the load on the DFK 33UX250.AS's processor. Should, on the other hand, you prefer that the camera itself performs color interpolation, you can select the appropriate option in IC Capture.AS. This enables the transfer of data to reach the camera's maximum of 75 FPS. Finally, if you do not require color interpolation at all, you can turn it off completely and the image stream is written to disk in RAW format.
The DFK 33UX250.AS ships with the color Sony IMX250LQ progressive scan CMOS Pregius chip. With its 2/3 " format, the CMOS Pregius chip produces a resolution of 2448 x 2048 pixels. Thanks to this extremely high quality, the Sony IMX250LQ CMOS Pregius chip is also often used in other scientific, industrial and medical image processing applications.
Unlike the human eye, CMOS Pregius chips are sensitive to near infrared light (wavelengths over 700 nm). The DFK 33UX250.AS ships with an IR cut filter as standard and is thus suited to applications in which these wavelengths would lead to interference or undesirable results.
In order to transfer the vast amount of data created by the stream of uncompressed and lossless color images to the host PC, you need a very high speed bus. Hence, the DFK 33UX250.AS is fitted with a fast USB 3.0 connector.
The DFK 33UX250.AS ships with the device driver and the camera control and image acquisition application IC Capture.AS. Both of these run on Windows 10, Windows 7, Windows Vista and Windows XP (32 and 64 bit).
