LC99063-LF2

Major Functions

Luminance (Y) signal processing

• This block includes an 11-tap low pass filter.

• This block includes a gamma correction circuit using a five-segment curve with user-specified data points.

• This block provides vertical and horizontal outline enhancement with user-specified gain and coreling.

• This block includes a circuit for generating the 1.5× oversampling frequency.

Chrominance (U.V, U/V) signal processing

• This block uses a 9-tap low pass filter and color matrices to convert YUV input to an RGB signal.

• This block includes an auto white balance subblock.

— This subblock contains all circuits necessary for automatic white balance adjustment.

— This subblock offers a choice of automatic or manual operation.

— This subblock supports holding of automatic operation results.

— This subblock offers a choice of seven patterns—one for skin tones, for example.

• This block includes a gamma correction circuit using a three-segment curve.

• This block uses adjustable linear matrices to convert the color difference signals.

• This block includes an adjustable circuit for suppressing color noise at low luminance levels.

• This block includes an adjustable circuit for suppressing false-color signals occurring at edges and high-luminance

blocks.

• This block includes a circuit for generating the 1.5× oversampling frequency.

NTSC encoder

• This block encodes the RGB data using the timing from the HD, VD, and CLK (14.31818 MHz) input signals.

• This block supports color burst phase adjustment.

• The pedestal and burst levels are both adjustable.

I/O modes

• Input modes

— In addition to LC99053 output signals, the chip supports the Y, U, and V input configuration (Y.U.V) and the Y

and U/V one (Y.U/V).

— The chip can mix (superimpose) the signals from these two sources.

• Output modes

— Digital outputs: Digital composite video, digital Y.C, R.G.B, Y.U.V, and Y.U/V.

— Analog outputs using two 8-bit digital-to-analog converters: Composite video and Y.C

Other functions

• Registers are accessible via a 3-pin serial interface.

• The chip is capable of stand-alone operation.

• The chip supports mirror imaging (reversal of left and right).

• The chip supports pseudo interlacing.

• The chip supports negative imaging (creation of photographic negatives).

Important Notes

When used in combination with the LC99053-Z28, this chip supports the following modes with field periods longer than

1/60 second: extended exposure, M3, M4, and external ST and FT trigger. In these modes, however, the system requires

even more careful evaluation of circuit constants, trigger inputs, and other factors affecting CCD and driver operation.

Camera characteristics depend heavily on part layout and circuit design, so follow the guidelines set forth in

recommended circuit diagrams issued by Sanyo.
