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.

5 Why Multishot is an improvement Pixels and Alcohol* *Inspired by: presentation by Joachim Linkemann from Basler AGpresentation by Joachim Linkemann from Basler AG

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

16 Almalence multi-shot solutions Super Resolution Zoom HDR BlurLess Exposure Panorama Object removal More to come
