Image processor developer Hisilicon has released the Hi3559A System-on-Chip (SoC) for high-speed video processing applications, it’s the first processor for Hisilicon Smart Vision Platform (SVP). The Hi3559A supports 8K ultra HD H.264/AVC and H.265/HEVC at 30 frames per second for multiple video streams with equivalent performance, for example VR camera that uses dual 4K/120fps sensors.
The new image processor is based on Dual-core Cortex™-A53 & dual-core Cortex™-A73 architecture provides significant processing power for customer applications including 360 panoramic camera, VR, computer vision. The Hi3559A can support 10-bit H.265 High Dynamic Range (HDR) video processing to handle high contrast and wide color range scenes. Intending to cater the applications for 360 degree cameras, Hi3559A support 8-channel CMOS sensor signal input and image hardware stitching.
Slow motion technology has been applied in video shooting by smartphone and professional camcoder. Slow motion means shoot video with a high speed frame rate, while play video in real-time rate. For example, when shooting 4K video footage at 120fps, and playback in 30fps, all the motion will be slower 4 times. Slow motion is also called high-speed shooting, it’s common in movie shooting, it’s also an essential feature for security cameras to capture plate number of high-speed running vehicle in traffic video surveillance applications.
To shoot high-speed video, the camera’s hardware must be high-end. Typically, the critical requirements including:
