While auto-blinking: the cursor X position controls the blink rate and cursor Y position controls the proportion of time spent on each plane. In auto or manual blink modes: button A selects manual mode and the next channel, button C selects auto-blinking, button B selects image enhancement of both images together, and button D causes the verb to exit. During the image enhancement, the left hand half of channel A appears with the right hand half of channel B on the TV screen. In this mode, the cursor X position controls the intercept and the cursor Y position controls the slope of the (linear) transfer function. Buttons A and B may be used to select channels A and B, resp., for individual enhancement. Button C will switch the sign of the slope and Button D will return the verb to the blinking mode. Adverbs: TVCHAN.....Selects TV channel to be "channel A" TV2CHAN....Selects TV channel to be "channel B" If either are out of range, 1 and 2 are used. On TVs which support split screen, channel A will appear on the left (or top) half during enhancement functions. ----------------------------------------------------------------
