Figure 3-5. DLP LightCrafter 4500 GUI – Pattern Sequence Mode
The Pattern Sequence displays images from one of the following two input sources:
• Flash: Images stored in flash memory. The flash memory can store up to sixty-four 24-bit compressed
images.
• Video port: Streamed through the Parallel RGB or FPD-link interface. Only one of these interfaces can
be connected to the DLP LightCrafter 4500 during Pattern Sequence mode.
To synchronize a camera or external system with the displayed patterns, the DLP LightCrafter 4500
supports a set of trigger inputs and outputs. These inputs and outputs are configured through the Trigger
Mode section and Trigger Controls subtab. The Trigger Mode selects the trigger input:
• Internal/External: Uses an internal trigger period to start the pattern sequence or uses the DLP
LightCrafter 4500 TRIG_IN2 signal to start and pause the pattern sequence. Each pattern in the
pattern sequence can be configured with either an internal or external trigger. With the Internal Trigger
setting, the Internal Trigger Period displays the next pattern. With External Trigger Period, the DLP
Light Crafter 4500 TRIG_IN_1 signal displays the next pattern.
• Vsync: Uses the VSYNC signal from the Parallel RGB or FPD-link interface to trigger the start of the
pattern sequence. After VSYNC, the patterns are displayed in the sequence shown on the Pattern
Sequence section. Each pattern length is determined by the Pattern Exposure time. Thus, the total
number of patterns multiplied by the pattern exposure must be less than or equal to the VSYNC period.
