TDA9171
FEATURES
- Picture content dependent non-linear Y and U,V processing by luminance histogram analysis
- TV standard independent
- Incredible blue stretch
- Optional YC-processing. GENERAL DESCRIPTION
The TDA9171 is a transparent analog video processor with YUV input and output interfaces. The luminance transfer is controlled in a non-linear way by the distribution, in 5 discrete histogram sections, of the luminance values measured in a picture. As a result, the QUICK REFERENCE DATA SYMBOL VCC supply voltage PARAMETER MIN. 7.2
- TYP.
TDA9171 contrast ratio of the most important parts of the scene will be improved. So as to maintain a proper colour reproduction the saturation of the
- U and
- V colour difference signals are also controlled as a function of the actual non-linearity in the luminance channel. Optionally, the YUV blue stretch circuitry can be activated which offsets colours near white towards blue. The supply voltage is 8 V. The device is contained in a 20 lead dual in-line...
