MT9P031: 1/2.5-Inch 5-Mp Digital Image Sensor
MT9P031 Image Sensor
Product Brief
Micron’s MT9P031 is a 1/2.5-inch CMOS digital image sensor with an active-pixel array of 2592H x 1944V. It incorporates sophisticated camera functions such as windowing, binning, column and row skip mode, and snapshot mode. It is programmable through a simple two-wire serial interface. The MT9P031 produces extraordinarily clear, sharp digital pictures, and its ability to capture both continuous video and single frames makes it the perfect choice for a wide range of consumer and commercial security applications, including high resolution network cameras; pan, tilt, and zoom cameras; and hybrid video/still cameras.
Applications
• High-resolution network cameras
• Wide field of view cameras • High-definition surveillance
camera • Dome cameras with electronic
pan, tilt, and zoom
• Hybrid video cameras with high resolution stills
• Detailed feature extraction for smart cameras
Features
• Micron® DigitalClarity® imaging technology
• High frame rate • Superior low-light
performance • 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
• Subframe windowed readout • Programmable controls: gain,
frame rate, frame size, exposure • Automatic black level calibration • On-chip PLL
