TDA9170
FEATURES
- Picture content dependent non-linear Y and U, V processing by histogram analysis
- Adaptive and variable gamma correction controls
- Black and white stretch capabilities
- Transparent I2C-bus control
- On-chip window generator for valid histogram measurement and black detection. GENERAL DESCRIPTION
The TDA9170 is a transparent analog video processor with a YUV interface. It offers three main luminance processing functions any bination of which can be selected. The luminance transfer is controlled in a non-linear manner by the distribution (in 5 discrete histogram sections) of the luminance values measured in a picture. As a result, the contrast ratio of the most important parts of the picture will be improved.
