OmniVision’s OV14810/OV14825 14.6-Megapixel high-definition (HD) sensor uses its most advanced 1.4-micron OmniBSITM (backside illumination) pixel architecture to achieve optimal performance and sensitivity in the industry’s smallest format. The 1/2.33-inch OV14810 has an active array of 4,416 x 3,312 backside illumination pixels operating at 15 frames per second (fps) in full resolution, or delivering full 1080p HD video at 60 fps, using a binning feature to achieve higher sensitivity. In full HD video mode, the sensor also provides additional pixels for electronic image stabilization (EIS).
The OV14810 and OV14825 differentiate in chief ray angle (CRA), which optimizes each sensor for its end application: DSC/DVC and mobile. The sensor’s small form factor, facilitated by its CSP packaging, allows for the development of ultra compact cameras. The OV14825 is also available in RW (bare die) for module integrators. The OV14810/OV14825 enables camera designs with a low-cost bill of materials and reduced power consumption. Both sensors are offered with industry-standard connectivity including LVDS, MIPI and DVP and do not require external IC components.
OV5640 is a complete ¼-inch 5-Megapixel system-on-a-chip (SOC) camera solution using OmniVision's latest 1.4-micron OmniBSI™ (backside illumination) pixel architecture with an embedded image signal processor and compressor, so that the output can be a complete JPEG picture, transferred via either a standard DVP port or high speed serial MIPI interface. There is also an on-chip microcontroller that, as an example, can control an external AutoFocus system.
The OV5650 is OmniVision's latest 5-megapixel imaging solution for mobile phones featuring 1.7-micron OmniBSI™ (backside illumination) technology. OmniBSI delivers a number of performance improvements over front-side illumination (FSI) technology, including increased sensitivity per unit area, improved quantum efficiency, reduced crosstalk and photo response non-uniformity, which all lead to significant improvements in image quality.
Designed specifically to address consumer demand for digital still camera (DSC) quality imaging in a mobile phone, the OV5650 combines the industry's best low-light sensitivity at 1300mV/lux-sec and a 2X improvement in (SNR10) signal-to-noise ratio (<70 lux) with the industry's lowest stack height – ideal for today's ultra-slim mobile phones.
The superior pixel performance of the 1/3.2-inch OV5650 enables high frame rate HD video at 60 frames per second (fps) with complete user control over formatting and output data transfer. The OV5650 supports a digital video parallel port or two-lane MIPI, and provides full-frame, windowed or scaled 10-bit images in RAW RGB format, and 256 bytes of available on-chip memory.
Automatic image control features and high frame rates for video encoding deliver vivid still and video images, even in the most challenging lighting conditions.
The OV3650 color sensor provides the most advanced pixel quality on the market today. Featuring OmniVision's high-sensitivity 1.75-micron OmniPixel3-HS™ pixel architecture, the OV3650 delivers double the sensitivity (960m V/lux-sec) of competing devices resulting in best-in-class low-light performance. The OmniPixel3-HS architecture is the latest and most advanced generation of OmniVision's family of front side illumination (FSI) pixel architectures. OmniPixel3-HS significantly enhances image capture under very low lighting conditions, enabling a new generation of compact camera solutions for mobile handsets, notebook, webcam and other applications that require exceptional low-light performance without the need for flash. The OV3650 color sensor is a low-voltage, high performance 1/4-inch 3-Megapixel CMOS image sensor that provides the full functionality of a single chip QXGA (2048 x 1536) camera in a small footprint package.
The OV3650 provides full-frame, sub-sampled and windowed 10-bit images in various formats via the SCCB interface and offers an image array capable of operating at up to 15 frames per second (fps) in QXGA resolution. All required image processing functions, including exposure control, white balance, and defective pixel canceling, are programmable through the SCCB interface. Elimination of image contamination issues such as fixed pattern noise, smearing, and blooming produces a clean, fully stable color image. For customized information purposes, the OV3650 includes a one-time programmable (OTP) memory. The OV3650 has a one lane MIPI interface and a traditional parallel digital video port. The sensor's parallel port can also be used to communicate to an external secondary camera (digital video port) while providing continued output through the MIPI interface.
The OV2720 is the world’s first 1/6-inch, native 1080p/30 high-definition (HD) CMOS image sensor designed for notebook, webcam and video conferencing applications. Enabled by OmniVision’s proprietary 1.4-micron OmniBSI™ pixel technology, the OV2720 allows for extremely thin camera modules with a z-height of 3.5 mm, while delivering video conference quality 1080p HD video, making it an ideal choice for the next generation of ultra-thin, HD video-enabled notebooks.
A native HD sensor, the OV2720 enjoys optimal performance because it does not suffer from degradation or image artifacts due to scaling or cropping. Instead, native HD enables full field of view video with optimized image quality, sensitivity, color reproduction and clarity. Enabled by OmniBSI technology, the sensor achieves best-in-class low light sensitivity of 680-mV/lux-sec. Using a binning feature, OV2720’s low-light performance can be double that of similar-sized VGA sensors, making it an ideal choice for video conferencing and webcam applications.
The OV2720 supports multiple platform architectures and controllers with both parallel and MIPI interfaces. It allows system designers to leverage the same opto-electrical design across various products and multiple market segments to reduce product development time.
