EAGLE (Figure 41)
The Eagle circuit provides Skin tone correction, Blue stretch, and Green Enhancement. In
versions equipped with the Pixel Plus feature, the Eagle IC performs the corrections for this
mode.
The video frames are sent to FM4 and FM5, 7722, and 7723 memories from the FALCONIC
IC. These memory ICs hold the frame data until they are required for processing by the
Eagle. The Input Multiplexer selects which frame is to be read. The Vertical and Horizontal
Peaking circuit sharpens the edges and adds blue pixels to enhance the picture. This circuit
is part of the Pixel Plus processing.
The Scaling circuit scales the picture to 1280x720 pixels to conform to the Light Engine dis-
play. The YUV format circuit converts the picture to conform to the MSB (Main Scaler Board)
input. The Eagle is controlled by the Microprocessor in the PICNIC IC via the SNERT inter-
face. The Eagle outputs a 8-bit digital Y and UV signal to the LVDS transmitter.
