Preliminary speciﬁcation

YUV picture improvement processor based

on histogram modiﬁcation

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.

Black restoration is available in the event of a set-up in the

luminance signal. A variable gamma function, after the

histogram conversion, offers the possibility of excellent

brightness control.

GENERAL DESCRIPTION

The TDA9170 is a transparent analog video processor

with a YUV interface. It offers three main luminance

processing functions any combination of which can be

selected.

To maintain a proper colour reproduction, the saturation of

the U and V colour difference signals are controlled as a

function of the actual non-linearity in the luminance

channel.

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.

The TDA9170 concept has maximum flexibility with the

optional on-board I²C-bus (including hardwired address

select) and window control. The supply voltage is 8 V. The

device is mounted in a 32 pin SDIP envelope.
