Imaging
As CMOS camera sensor technology advances with efficient packaging of multi-million pixel devices, the need for equally efficient image processing pipelines is becoming obvious. In a CMOS sensor, there are many issues such as dark currents, defective pixels, and sensitivity to temperature and humidity. Today the trend is towards building:
- High resolution cameras
- Wide dynamic range sensors with deep color
- High frame rate designs
There are many processing blocks in an image processing pipeline:
- Denoising of raw sensor output
- Demosaicing Bayer color filter array output
- Defective pixel correction
- Lens shading correction
- Color correction and tint adjustment
- Tone mapping
- Gamma correction
- Special effects processing
- Auto White Balancing
- Auto exposure control
- Auto focusing
- Color conversion to YCbCr
- Higher level
processing such as:
- Face detection
- Red eye removal
- Closed eye detection
- Skin color detection
- Image stabilization
- Image scaling
- Correction for low or high level exposure
- Image rotation
- Synchronizing to Flash
We can be of help in the design process in all the above blocks and overall pipeline design.
