Three new visual technologies to comprehensively improve image quality and coding efficiency

Multi-camera stitching solution, based on RK3588, RV1126 and RV1106, can meet different product requirements. RK3588 multi-eye splicing solution, with dual 24M ISP processing capability, built-in Rockchip self-developed ISP3.0, upgraded HDR synthesis and multi-level noise reduction algorithm, can realize the detailed performance requirements of high dynamic scenes and night vision effects in starlight scenes Requirements; support 2~6 meshes of Sensor input, enabling panorama stitching; support 8K@30fps H264/265 encoding output, high-definition and smooth video shooting; built-in multi-core NPU, providing up to 6TOPS computing power, meeting the video structure requirements of high-end IPC complex scenes. The RV1126 and RV1106 binocular stitching solutions support horizontal FOV 170-degree stitching, and the resolution supports 4M25 frames and 2M15 frames respectively. Among them, the RV1106 binocular splicing solution is the preferred solution with high-cost performance in the market.

The RV1126/RV1109 AI ISP solution has two built-in core algorithms, low-light noise reduction and intelligent enhancement. Low-light noise reduction is based on artificial intelligence algorithms, and deep learning is performed on the picture noise data of videos and pictures; intelligent enhancement makes details clearer through super-perception of details, and adaptive texture enhancement. Based on the characteristics of the two types of algorithms, the RV1126/RV1109 IPC solution can make the product show obvious advantages in various complex light environments, such as low-light and low-light environments, still showing no smear, low noise, and clearer pictures.

RV1106 intelligent coding scheme, with super coding performance, aims to provide customers with a feasible solution with an extremely low bit rate. It has three advantages. First, the output bit rate fluctuates dynamically according to the complexity of the scene and the proportion of ROI, which can improve the image quality of ROI and keep the image quality of non-ROI unchanged. The bit rate is greatly reduced to save transmission bandwidth; second, the image quality is guaranteed to be Subjectively lossless while reducing the bit rate. After outdoor GOP comparison and actual measurement, under the premise of the same bit rate in the same scene, the RV1106/RV1103 solution has better picture quality than other solutions in the market, and the effect of motion smear convergence is better; third, static In the scene, the bit rate is adaptively saved. Under the test condition of 1440P 15fps, the bit rate is more than 20 times lower than that of the conventional mode. The shooting picture is high-definition, and the video volume is smaller, which can save storage and ensure smooth video playback in a weak network environment.瑞芯微电子
