LC99452
Modes of Operation
The LC99452 has been especially designed for high-resolution low cost digital photography in color full 1600 × 1280
resolution and real-time monitoring (preview) mode in color at reduced resolution. Two main modes of operation are
possible:
Still picture mode (mode-1)
In still picture mode, a 1600 (H) × 1280 (V) progressive scan image can be read out. A 'single shot' mechanical shutter is
required to obtain a 100% smear free image.
Preview mode (mode-2)
In preview mode, image with a reduced vertical resolution by on-chip data compression can be obtained. Progressive
scan images (mode-2), e.g. 120, 240 or 288 lines at up to 40 images/s, suitable for LCD displays can be selected by the
timing generator.
