12.3 BR Size Adjustment
After setting the image position, move to the screen that allows adjustments to
the size of the image. You’ll be setting the position of the Bottom, Right pixel.
Although you can zoom and shrink the image using the powerful Corio2
capability, these adjustments are used to set the size of the image before any
changes are artificially made using zoom or shrink. You’ve set the position of
the first pixel in the previous adjustments and now you will want make certain
the image completely fills the screen without over expanding it in either
direction.
Pressing the Menu Select knob once will cause the left hand brackets to begin
flashing. You can then adjust the knob Clockwise or Counter-clockwise and
expand or shorten the width of the image. Notice that the left side of the
image stays locked where you positioned it with the TL Position Adjustment
but the image can be adjusted to fill the screen horizontally. Press the knob
again and the value is stored in temporary memory, the left-hand brackets
cease their flashing and the right hand set of brackets begin to flash. You can
now adjust the image vertically to fill the screen. As with the Horizontal
adjustment, the first pixel stays locked (and with it the top part of the image)
but you can expand or contract the vertical component of the image by
rotating the Menu Select knob.
As with the TL Adjustment, you must select the source you wish to adjust via
the input buttons.
12.4 Input Pixel Phase
Although a pixel is a very small element of the total image, it’s possible for the
Scaler’s A to D converters to randomly sample the picture on the edge of the
pixel thereby losing image resolution. The Input Pixel Phase screen allows
you to sample the image precisely in the middle of the pixels.
To make this adjustment, select an RGB source and then provide an image
from that source with fine detail, preferably with very sharp vertical lines such
as a multi-burst signal. In the absence of a multi-burst signal, use something
with as fine a vertical detail as possible.
Press the Menu Select knob once and the brackets will begin to flash. Adjust
the knob Clockwise and Counter-clockwise for the sharpest picture with the
least shadowing or noise. When done correctly, any subsequent image from
the adjusted source will be sampled in the middle of its pixels. All images from
