OmniVision Technologies has introduced a ¼inch, 5Mpixel, RAW CMOS image sensor based on its 1.4µm OmniBSI backside illumination technology. The OV5647 offers the performance and size benefits of backside illumination technology, claims the company, while allowing mobile phone designs to use existing baseband or applications processors for image processing functions. The sensor delivers a light sensitivity of 680mV/lux-sec, a low-profile z-height and small footprint, making it suitable for compact camera modules in mobile phones and notebooks. The high pixel performance of the device enables 720p HD video at 60frames/s and 1080p HD video at 30frames/s, with user control over formatting and output data transfer. A post-binning, re-sampling filter function of the device removes image artifacts around edges and minimises spatial artifacts to deliver sharp and crisp colour images. The sensor supports a digital-video parallel port or two-lane MIPI interface, and provides full-frame, windowed or binned 10bit images in RAW RGB format with complete user control over formatting and output data transfer.
