Denso has developed the world's smallest image sensor

Japan Denso Group has announced the development of the world's smallest new image sensor . The volume of this product is only 50% of that of traditional products. The conventional lane departure warning system incorporates the necessary sensor functions of the high beam automatic control system. It is the smallest volume of image sensor with equivalent functions in the world. .

In addition, the product has also successfully broken the upper limit of the operating temperature, even in summer or high temperature areas can also work safely and smoothly, is the world's largest operating temperature range of image sensors.

The image sensor is usually mounted at the upper position of the front windshield. Therefore, in order to facilitate the observer to observe and reduce the pressure, the miniaturization of the sensor becomes very necessary. However, integrating the lane departure warning system and the high beam automatic control system requires a plurality of image processing integrated circuits, so it is difficult to achieve miniaturization.

Faced with this issue, Denso has developed an algorithm with higher performance, and the integration of a lane departure warning system and a high-beam automatic control system has been realized by a general-purpose microcomputer. At the same time, the general-purpose microcomputer was also developed for high-temperature work, so as to realize the miniaturization of the sensor and ensure the operating temperature. In addition, the camera mounted on the image sensor also changes from black and white to color. As a lane departure warning system, it can be applied to various road markings of various countries in the world; as a high beam automatic control system, it is also easier to identify the rear vehicle tail lights and other light sources.

This newly developed small image sensor is scheduled to start in July. It will be sold first in China with Lexus ES as an option, and will be gradually sold in North America, Russia, and the Middle East. At the same time, the number of models to be installed will also continue to increase.

Ever since, Denso has always adhered to the goal of "a society that achieves zero traffic accidents" and has continued to develop and put into practical use safety technologies such as occupant protection and accident prevention. In the future, we will continue to make full use of the accumulation of past technologies and contribute to the realization of a safe and safe automobile society for drivers, pedestrians, and all people.
