Sleep mode This mode ensures that the coprocessor consumes the lowest possible power and I
control is possible. Patching should occur in sleep mode followed by setting the system clock
parameters.
Idle Mode The clock coming from the sensor is active and I
Viewfinder Mode The viewfinder mode can be used to display dithered images on low color depth
local LCD displays. The programmable gamma allows for a wide range of displays. Different image
sizes and data formats can be chosen.
