Description of the data path OSCAR Technical Manual V2.4 .0 84 Binning (only Oscar F-510C) 2xB i n n i n g Definition Binning is the process of combining neighboring p ixels while being read out from the CC D chip.
Description of the data path OSCAR Technical Manual V2.4 .0 85 Vertical binning Vertical binning increases the light sensitivity of the camera by a factor of two by adding together the values of two adjoining vertical pixels output as a single pixel. At the same time this normally improv es signal-to-noise s ep- aration by about 3 dB.
Description of the data path OSCAR Technical Manual V2.4 .0 86 Horizontal binning Definition In horizontal binning adjacent horizontal pixels in a line are combined in pairs. This means that in horizontal binning the light sensitivity of the camera is also increased by a factor of two (6 dB ).
Description of the data path OSCAR Technical Manual V2.4 .0 87 2 x full binning If horizontal and vertical binning ar e combined, every 4 pixels are consoli- dated into a single pixel. At firs t two horizontal pixels are put together and then combined vertically.
Description of the data path OSCAR Technical Manual V2.4 .0 88 Sub-sampling What is sub-sampling? Definition Sub-sampling is the process of skip pi ng neighboring pixels (with the same color) while being read out from the CCD chip. Which Oscar models have sub-sampling? All Oscar models have this feature.
Description of the data path OSCAR Technical Manual V2.4 .0 89 High SNR mode (High Signal Noise Ratio) To configure this feature in a n advanced register: See Table 101: Advanced register: High Signal Noise Ratio (HSNR) on page 197. In this mode t he camera grabs a nd aver ages a set number of images and out- puts one image with the same bit depth.
Description of the data path OSCAR Technical Manual V2.4 .0 90 Sharpness All Oscar models are equipped with a tw o-step sharpness control, applying a discreet horizontal high pass in the gr een channel as shown in the next three line profiles.
Description of the data path OSCAR Technical Manual V2.4 .0 91 RAW mode is accessible via Color_Mode Mono8, RAW8 and via Format_7. Color interpolation (BAYER demosaicing) In color interpolation, a red , green or blue value is determined fo r each pixel.
Description of the data path OSCAR Technical Manual V2.4 .0 92 Color corr ection Why color correction? The spectral response of a CCD is different of those of an output device or the human eye. This is the reason for th e fact that perfect color reproduction is not possible.
Description of the data path OSCAR Technical Manual V2.4 .0 93 Color correction can also be switched off in YUV mode with the help of the following register: Color conversion (RGB YUV) The conversion from RGB to YUV is made using the foll owing formulae: Hue and Saturation Oscar models are equipped with hue and saturation registers.
Description of the data path OSCAR Technical Manual V2.4 .0 94 This means a setting of zero changes the image to black and white and a set- ting of 511 doubles the color intensit y compared to the nominal one at 256.
Description of the data path OSCAR Technical Manual V2.4 .0 95 Serial interface All Oscar cameras are equipped with th e SIO (serial input/output) feature as described in IIDC V1.31.
