 5-Megapixel digital image sensor module
 Superior low-light performance
 High frame rate
 Low dark current
 Global reset release, which starts the exposure of all rows simultaneously
 Bulb exposure mode, for arbitrary exposure times
 Snapshot mode to take frames on demand
 Horizontal and vertical mirror image
 Column and row skip modes to reduce image size without reducing field-of-view
 Column and row binning modes to improve image quality when resizing
 Simple two-wire serial interface
 Programmable controls: gain, frame rate, frame size, exposure
Table 1-2 shows the key parameters of the CMOS sensor (Note*).
