STMicroelectronics VD6725 small 2megapixel optical-format imaging sensor

STMicroelectronics has introduced its smallest single-chip 2megapixel camera sensor for mobile applications.

The VD6725 is a 1/5-inch optical-format imaging sensor, with an active pixel array of 1600x1200 (UXGA), image processor and camera control functions on a single chip. It is designed to fit in phone camera modules smaller than 6x6x3.8mm due to its 1.75-micron pixel design.

The device's image processor will support features such as flipped and mirror-reversed images or pure black-and-white conversion for whiteboard content capture, document extraction and barcode reading.
IT will also produce digital video streams at 15frames per second at full UXGA resolution and 30fps at VGA resolution. It supports fast context switching, which means that the sensor switches extremely fast from 'preview' to 'capture mode', minimizing the delay of the capture control.

The single-chip camera sensor is available in the firm's Through Silicon Via wafer-level package. This type of package enables the production of reflowable camera modules which can be soldered directly on the phone motherboard.
