Sharpness
All Oscar models are equipped with a two-step sharpness control, applying a
discreet horizontal high pass in the green channel as shown in the next three
line profiles.
Color interpolation
The color sensors capture the color information via so called primary color
(R-G-B) filters placed over the individual pixels in a BAYER mosaic layout.
An effective Bayer RGB color interpolation already takes place in all Oscar
cameras. Before converting to the YUV format, color correction is done after
BAYER demosaicing.
Color processing can be bypassed by using the so called RAW image transfer.
RAW mode is primarily used to
• save bandwidth on the IEEE 1394 bus
• achieve higher frame rates
• use different BAYER demosaicing algorithms on the PC
