MMS auto-exposure is using sophisticated heuristic algorithms in order to calculate the best exposure for given scene, taking into account not only the brightness of the scene, but many additional factors as minimizing the motion blur in the captured picture, improving details in the shadows, compensating the backlight, etc.

Designed to work with or without Flashlight, when used with high power LED or Xenon, MMS autoexposure produces well exposure captures even in very tricky conditions.

Technical details:  

Modes

• Auto (default): Automatically corrects the exposure and gain of the sensor and image processing system
• Sport: Suitable for capturing moving objects or sport events
• Night: Extended exposure time (up to 200mS)‏
• Backlight: Suitable for capturing objects with backlight illumination
• Very long: Very long exposure time (to be used with dark frame subtraction)  

Features

• Metering: Normal, Center, Wide , Selectable area, Face prioritized
• Control: On, off, suspend
• Exposure compensation: -3 to +3 EV, 0.1EV increments
• Manual settings: Time, Gain, Aperture
• Prioritization: Shutter, Exposure, Face area
• Zoom tracking:
• Fast convergence option for improving start-up and autofocus latency
• Rolling and mechanical shutter support
• Diaphragm and ND filter support
• Video-light support for preview.
• For capture, high-power LED flash or Xenon flash with optional photosensor are supported and pre-flash is used for precise exposure control.  
• Global and local brightness enhancements support
• Face prioritization support
• Flicker reduction: 50Hz, 60Hz or Auto (optional)
