Smartphone camera trends Multiple cameras built-in to enable
• DSLR-like experiences • Visual processing
World’s 1st real-time shallow depth of field
effects during preview
Current Smartphones
Only by post processing
Camera experience of the future –
Visual processing
What it can do
• Instant depth of field / Distance detection • Instant object classification / Identification
How this will impact users
• Accurately identify unknown objects anywhere • Disruptive to education & lifestyle
Non-contact heart rate detection by video camera
Vision processing by CPU / GPU / ISP heterogeneous computing Visual processing application
Object Recognition
Recognition Engine
• Recognize multiple objects
• Boost performance by SW/HW co-optimization
Augment recognized information onto your display
Recognize wallpapers and display relevant content in real time
Introducing CrossMount™:
Today, apps can utilize on-device resources only
Apps on one device can only utilize HW
resources within the same device. Application Framework Mem. Driver OS Kernel Sensor Driver Disp. Driver Others … Apps
CrossMount™ enables cross-device resource utilization,
when in the same network
