2. Imaging – why is it important? The smartphones become more and more alike Camera features and quality can still make the difference

3. How to boost Camera performance? Mobile camera has fundamental limitations due to: Tiny lens Small pixels No optical zoom The solution: use MULTISHOT techniques

4. How to boost Camera performance? An example: Human eye has only 1:100 dynamic range (less than a mobile camera). It is not possible to physically improve the eye But, by re-scanning the scene and re-adjusting it can capture up to 1:1,000,000 dynamic range! So the physical ‘device’ is improved 10000 times by proper capturing and post processing.

6. Full-well and Saturation Capacity Full-well Saturation Each pixel has a maximum capacity to collect electrons.

7. Signal to noise ratio The „noise“ is equivalent to the Refill levels

8. Dark noise There is some remaining noise, although no light hits the sensor.

9. Dynamic range Saturation Dark noise Dynamic range = Full / Empty = Saturation Cap. / Dark Noise Dynamic range

10. Pixels get smaller SNR and dynamic range diminishing

11. Multi-shot Easy way to: Multiply SNR Increase dynamic range Improve low-light performance Improvement proportional to

12. Resolution Displacements between the shots make it possible to increase resolution

13. Curses of multi-shot Mis-alignment: Spatial Radiometric

14. Curses of multi-shot Moving objects = Ghosting

15. Almalence answers Sub-pixel accuracy spatial alignment: Almalence has carried it's DSLR expertise into mobile world Rolling-shutter effects mitigated Precise radiometric alignment Sophisticated de-ghosting techniques suitable for various multi-shot scenarios Proprietary patented technologies
