Honghan Micro focuses on professional ISP chips with fully independent intellectual property rights, covering the entire chain of chip design, algorithm research and development, and toolchain development. Its core competitiveness is reflected in the following aspects:

1. ISP Characteristics of chip technology

ISP（Image Signal Processor, The image signal processor is the brain of the camera, responsible for processing the raw signals captured by the sensor into clear images. The core technological advantages of Honghan Micro ISP chip include:

 

• Fully proprietary core IP: Self developed MIPI、USB、AWB/AE/AF（3A algorithm）、AI noise reduction and other Software and hardware IP,Get rid of foreign technology dependence and be compatible with Windows, Android, HarmonyOS Linux、 Kirin OS and other multiple systems;
• Low power consumption and wide temperature adaptability: The working current is 50mA (excluding sensors), and it can operate stably in extreme environments ranging from -40 ℃ to 125 ℃, suitable for harsh scenarios such as automotive and industrial applications;
• Innovation in Transmission and Integration: Pioneering USB signal enhancement technology, ordinary cables can achieve over 7 meters in length 2K@60fps High definition transmission; Supports synchronous transmission of video and audio (microphone+speaker) and power supply through a single USB interface, unique in the industry;
• Efficient image processing: Built in multimodal hardware noise reduction engine (dark state noise reduction, color noise removal), edge overflow processing, intelligent bad pixel compensation, clarity enhancement and other modules to improve image quality details;
• Low cost and easy to develop: ASIC Architecture design, simple peripheral circuits, coupled with an independent visual debugging toolchain, reduces the difficulty and cycle of customer development.
