JVCKENWOOD Corporation is pleased to announce that it has newly developed the image signal processing IP IPSILOS. The newly developed IPSILOS is based on the image signal processing SoC*3 FALCONBRID, which has been used in our consumer and professional camcorders, and has enhanced and expanded basic performance. We intend to install this IPSILOS in our products as a technology to improve the image quality of video-related equipment used in various applications such as in-vehicle products, and also provide it to other companies.

Background to the project

In recent years, the sophistication of cameras mounted on smartphones has been accelerating, and there is an extremely high market demand for high image quality in video-related equipment, including dashcams, which are one of our core products.


Given this market background, we have developed a new image signal processing IP IPSILOS based on our proprietary image signal processing SoC FALCONBRID, which has contributed to the high image quality performance of our products by utilizing the knowledge and expertise on high image quality cultivated over the years. We intend to install IPSILOS in our various types of video-related equipment. We are also expecting to provide this IP to manufacturers developing signal processing SoCs used in smartphones and other various markets as a technology to realize higher image quality of video-related equipment. Starting with the development of this IPSILOS, we will consider providing our various image signal processing IPs to other companies. We will work with SoC developers to create more image quality enhancement technologies.

Overview of the image signal processing IP IPSILOS

IPSILOS which we have developed is a circuit block commonly called an Image Signal Processor (ISP), a signal processing circuit that mainly receives RGB electrical signals from a sensor module and converts them into Y/C video signals. In addition to installing IPSILOS in our products, we will provide IP as circuit design data and control driver software environment as Software Development Kit (SDK) for a wide range of applications such as licensing and cooperative development with other companies.


This will not only enable semiconductor manufacturers to easily develop SoCs that realize industry-leading high-quality videos by using IPSILOS, but also enable product developers who are supplied with SoCs to develop a wide range of product lineups in a short period of time by setting various video parameters using the SDK.
