High Performance 8-Megapixel Camera With Advanced
OmniBSI+ Pixel Architecture for Superior Image Quality
With Low-Cost Structure
The 1/3.2-inch OV8825 is an 8-megapixel CameraChip™ sensor
built on OmniVision's advanced OmniBSI+™ pixel architecture,
providing many significant improvements over the previous
OmniBSI™ generation, including a 60 percent increase in
full-well capacity, a 10 percent increase in quantum efficiency
and a 10 percent improvement in low-light sensitivity.
OmniBSI+ pixel architecture enables the OV8825 to
dramatically improve image and video capture in both bright
and low-light conditions, making it a highly attractive solution
for next generation for smartphones and tablets.
The OV8825 operates at 24 frames per second (fps) in full
resolution, and in 1080p high-definition (HD) video mode at
30 fps or 720p at 60 fps. The sensor's high frame rate also
helps eliminate image lag for shutter-less designs, and enables
continuous shooting, minimized rolling shutter effect and
real-time image capture with no lag between resolutions. A
high-speed, 4-lane MIPI interface facilitates the required high
data transfer rates necessary for capturing 10-bit 8-megapixel
images and HD video.
An integrated scaler offers electronic image stabilization and
enables it to maintain full field-of-view (FOV) with improved
signal-to-noise performance in 1080p high-definition (HD)
video mode at 30 fps. The sensor's 2 x 2 binning functionality
with a post-binning re-sampling filter function minimizes
spatial artifacts and removes image artifacts around edges,
delivering clean, crisp color images.
The OV8825 fits into the industry standard 8.5 x 8.5 mm
module size and features certain image processing functions
such as lens shading correction and defect pixel correction,
as well as 256-bytes of embedded one-time programmable
memory.
