Introduction
This manual describes the usage of the Phoenix PC-1280 USB Dig-
ital Camera products. The brief introduction of the PC-1280 prod-
ucts in this chapter is followed by the installation, the operation of
the camera hardware/software, then a chapter talks about the work-
ing theory of the products. Several appendices at the end of this Us-
er’ Guide list specific detailed information as references to the user.
1.1 Phoenix Digital Camera
The Phoenix PC-1280 USB Digital Camera is a line of high-reso-
lution progressive scan digital cameras. The PC-1280 Camera is
designed to provide high quality video/images for Professional,
Medical, and Industrial applications with low cost. It provides
Plug-n-Play and hot swappable feature, and the video/image cap-
ture and camera control functions are through the 480 Mb/s high
speed USB 2.0 interface.
Two versions of Phoenix Camera are available. PC-1280/M is the
monochrome version and PC-1280/C is the color version. The PC-
1280/M is a monochrome digital camera with 10 or 8 bit black/
white pixel formats. It also supports the CCIR 601 YCbCr (YUV)
pixel format (16 bit) for easier Windows Overlay Display. The PC-
1280/C supports several user selectable pixel formats. They are the
Raw Bayer (8 or 10 bit), the CCIR 601 YCbCr (YUV-16 bit) and
the RGB (24 bit) formats. The RGB and YUV color video is pro-
duced using a bi-linear interpolation algorithm, in real-time, by the
PC1280/C camera. This gives the user a choice of the best pixel for-
mat for the application without the burden of doing software format
conversion.
There is a built-in 10 bit LUT in the PC-1280 Camera. For 8 bit pix-
el modes, the LUT can be loaded with a 10 to 8 mapping. For the
PC-1280/C model, a second 8 bit LUT is added after the color
space converter. This LUT works with the YUV pixel format only.
It has two 8 bit paths, one for Y the other for U/V.
