Problems in digital cameras are not limited to demosaicking and white balance. Here are examples of outstanding problems that you may or may not have heard of before.
- Public perception of "megapixel count"
- Sensor noise problems--low light regimes
- Optical diffraction and minority carrier diffusion (crosstalk)
- Compressed dynamic range of CMOS sensors
- Sensor binning and artifacts
- Modularized ASIC/co-processor design
- Bad pixel amelioration
- Multiple illuminant estimation
- Image and color enhancement
- Storage/transmission of high data-rate multimedia
- Standards and their adaptation
Workshops and seminars covering various topics in digital camera pipeline.
