Qualcomm announces its 5G-ready 7nm Snapdragon 855 platform featuring an enhanced imaging functionality:

"Snapdragon 855 sets new standards for capturing stunning photos and videos. The new Qualcomm Spectra™ 380 ISP integrates numerous hardware accelerated computer vision (CV) capabilities, enabling the world’s first announced CV-ISP to provide cutting-edge computational photography and video capture features while at the same time offering up to 4x power savings. The CV-ISP includes hardware-based depth sensing which enables video capture, object classification, and object segmentation all in real-time in 4K HDR at 60fps. This means a user can capture a video and accurately replace selected objects or backgrounds in the scene in real-time all with 4K HDR resolution using over 1 billion shades of color. Even further, the new Qualcomm Spectra 380 ISP is the first announced ISP to support video recording using HDR10+, so the more than 1 billion shades of color can be captured with exceptional contrast and visual brilliance. Finally, in order to efficiently store this amazing content, Snapdragon 855 adds hardware acceleration for HEIF file format encoding, reducing file sizes by 50% for efficiently saving and sending user generated content."

Qualcomm Spectra 380 Image Signal Processor:

  • Dual 14-bit CV-ISPs; 22MP @30 fps concurrent dual cameras; 48MP @ 30 fps single camera
  • Hardware CV functions including object detection & tracking (Histogram of Oriented Gradients, Harris Corner Detection, Normalized Cross Correlation, Linear classification and optical flow) and stereo depth processing
  • Advanced HDR solution including improved zzHDR and 3-exposure Quad Color Filter Array (QCFA) HDR
  • 4K60 HDR video capture (HDR10, HDR10+ and HLG) with Portrait Mode (bokeh), 10-bit color depth and Rec. 2020 color gamut
  • Hardware-based Multi-Frame Noise Reduction (MFNR) for snapshot and Motion Compensated Temporal noise Filtering (MCTF) for video
  • Hardware-based Electronic Image Stabilization (EIS) solution within camera subsystem
  • A new modular ISP design with more flexibility to tap in and out of the imaging pipeline both in the RAW and YUV pixel domains
  • High frame rate capture for slow motion video (720p @ 480fps)
  • HEIF photo capture, HEVC (H.265) video capture


Update: Qualcomm publishes its SD855 camera presentation. Few additional slides from it:
