KYOTO, Japan, July 16, 2024 /PRNewswire/ -- Nuvoton Technology
Corporation Japan is set to begin mass production of a 1/4-inch VGA
(640x480 pixel) resolution 3D Time-of-Flight (TOF) sensor in
July 2024. This sensor is poised to
revolutionize the recognition of people and objects in various
indoor and outdoor environments. This capability has been achieved
through Nuvoton's unique pixel design technology and distance
calculation/Image Signal Processor (ISP) technology.
1. High Accuracy in Bright Ambient Lighting Conditions
Leveraging Nuvoton's proprietary CMOS image sensor pixel
technology and CCD memory technology, the new TOF sensor has four
memories in the 5.6-square-micrometer pixel compared to the three
memories of its conventional TOF sensor and achieves accurate
distance sensing by simultaneously controlling pulse light sources
and acquiring background light signals. It can provide the
precise recognition of the position and shape of people and objects
under various ambient lighting conditions.

2. Accurate Distance Measurement for Moving Objects
With four embedded memories within each pixel, Nuvoton's new TOF
sensor outputs distance images in a single frame. This innovative
design significantly reduces motion blur and measurement errors in
moving objects by capturing and calculating distance from four
types of imaging signals within one frame. This feature is
particularly suited for applications requiring dynamic object
detection and recognition, such as obstacle detection for
autonomous mobile robots (AMRs) and airbag intensity control in
vehicles.

3. Integrated Distance Calculation Circuit for Fast and Accurate
Sensing
Nuvoton's new TOF sensor is equipped with an integrated distance
calculation circuit and a signal correction ISP, enabling it to
output high-speed, high-precision distance (3D) images at up to 120
fps (QVGA) without delay. This eliminates the need for distance
calculation by the system processor, reducing the processing
overhead and enabling faster sensing systems. Additionally, the
sensor can simultaneously output distance (3D) and IR (2D) images,
useful for applications requiring both high precision and
recognition/authentication functions.
