Section 7:Picture Mode
Picture mode is intended solely to assist in input source identification of TV
video (picture) signals. If non-picture test signals are viewed, the signal patterns
will be displayed, but no meaningful information may be extracted from the
display.
Pressing the Picture button brings up a low-resolution TV display with a
software generated pseudo-gray-scale. The number of the system line is always
displayed, and Select Line is always on. A bright line indicates the position of
the system line on the display. You may quickly set the line selection to a visual
reference point in the picture display and then switch to the waveform mode to
view the contents of that line.
Two soft keys are available for use in adjusting the display. When Picture mode
is active the Display and Graticule hard keys change their action. Turning the
knob while holding the Display button in adjusts the picture brightness. When
the Graticule hardkey is held in, turning the control knob adjusts the picture
contrast. Both brightness and contrast can be reset to their default values using
the Adjust/Default Brightness and Adjust/Default Contrast soft keys.
