OmniVision Technologies today launched its OV9655, a newly improved 1.3 megapixel CMOS image sensor (CIS) for mobile applications. With significant improvements in its pixel performance, the new sensor offers added features and higher image quality.
One key feature of the OV9655 is an LCD scaler, which allows handset makers to scale images to the exact size of the phone and eliminates any horizontal or vertical scaling bars on the LCD screen without the need for a more expensive backend DSP. In addition, the OV9655's improved DSP process improves the sensor's image processing capabilities, resulting in greatly enhanced image quality.
The OV9655 is based on OmniVision's proprietary OmniPixel(TM) technology platform, which has proven critical in meeting customers' high image-quality requirements. The OmniPixel technology's unique pixel architecture significantly increases the signal-to-noise ratio, which enables the OV9655 to perform exceptionally well in low-light conditions.
The OV9655 is a 1/4-inch, low-voltage CIS offering the full functionality of a single-chip SXGA (1280 x 1024) camera and image processor. It supports image sizes SXGA, VGA and any size scaling down from VGA to 40x30. The OV9655 also has a strobe mode that allows it to work with an external flash or LED.
The OV9655 provides full-frame, sub-sampled, scaled or windowed 8-bit/10-bit images in a wide range of formats controlled through a serial camera control bus (SCCB) interface. All required image processing functions including exposure control, gamma, white balance, color saturation, hue control, white pixel canceling and noise canceling are programmable through the SCCB interface.
