Security cameras are intended to capture images of suspicious persons and activities, so they must be able to capture high resolution images.
However, in situations such as “status monitoring” of the number of people who pass through ticket gates or automatic doors, or “safety monitoring” of elderly people or children in bedrooms or bathrooms, consideration must be made for privacy, so there is demand for low resolution monitoring of the presence or movement of people and things.
We have now added two distance image sensor products (128×8 pixels, 320×20 pixels) and a dedicated ASIC to our lineup of products that can be used in such situations.
A distance image sensor measures the distance to objects, and it can image the silhouette of the object from the distance information it acquires.
・Prepared 2 types of different number of pixels (128 × 8 pixels, 320 × 20 pixels)
・Higher sensitivity in the near infrared region (compared to previous products)
・Improved tolerance to background light (compared to previous products)
・Compact chip size package (CSP) type
Distance image sensors S16443-01WT, S16444-01WT
Image example (distance detection to people by using S16443-01WT)
Showing imaging examples in assumed situations such as people counter, gesture detection and safety monitoring by using 128 × 8 pixels sensor.

It outputs data in such a format as to be directly connected to a microcontroller. It helps to make devices smaller and lighter compared to the case where a general-purpose IC is used. It can be used for all distance image sensors.
・3.3 V power supply operation
・Built-in 12-bit A/D converter (× 2 ports)
・Output timing signals for sensor and light source
