Highlights
MMS HDR uses multiple frames from a conventional image sensor
The algorithm fuses three frames captured with different exposure settings:
- Normal (+0EV), x¼ Dark (-2EV) and x4 Bright (+2EV), meaning 16x difference in brightness between dark and bright images – enough for practical cases
MMS HDR avoids ghosting
- Detects moving objects and does not fuse the corresponding areas to avoid ghosting artifacts
- Even large moving objects are handled properly
- Recovers overexposed areas, which are occluded by moving objects in the dark image
MMS HDR uses both gyro-based and features-based alignment
The images are aligned to each other before fusion
- If Gyroscopic sensor is available it is used to speed-up the process of images alignment (precise time stamps are necessary in this case)
- If no Gyroscopic sensor is mounted, the algorithm uses features detection and tracking for alignment
MMS HDR features local and global brightness and contrast enhancement
To enhance the visual quality of produced image, brightness and contrast enhancement is incorporated.
