An image sensor, which is said to have combined classic 2D video imaging and 3D image recognition, has been announced by ON Semiconductor and is available from FRAMOS.

The AR0430 CMOS digital sensor is designed with a small 1/3.1-inch optical format and according to ON Semi, will deliver high-quality images with advanced 2.0 µm pixel stacked BSI technology and a 4 Megapixel resolution at 120 frames per second (fps).

ON Semi continues by saying the depth mode will enable depth mapping concurrently, while shooting video at 30 fps. It explains that the device has been designed to empower innovative industrial and consumer end-product applications with its 3D features.

With an active-pixel array of 2312 (H) x 1746 (V), On Semi says it is able to achieve a 4:3 aspect ratio and provide low-power performance when a 4MP data stream is operating at 30fps. The low power monitoring mode, which draws 8mW in standby, is also designed to be valuable in battery-powered security applications.

The AR0430 in standard imaging mode, is said to provide high quality images in both day and night lighting conditions. According to ON Semi, this imager, with a large linear full well capacity and high dynamic range, succeeds in challenging light conditions with leading color performance. It can record video at 120fps in slow motion mode and use the zoom feature, while retaining the resolution quality suitable for wearable devices. The feature of depth data at 30fps should promote the possibility of object recognition, virtual replacement, or downstream AI, that can interpret data for autonomous decisions or touchless device control.

ON Semi claims it has enabled simultaneous video and depth mapping via its super depth technology, built on the latest stacked die technology.

Super depth technology, together with the colour filter array feature and on-pixel micro-lenses, has been developed to create a data stream containing both image and depth data. On Semi explains that this data is combined off the sensor, via an algorithm, to deliver a 30fps video stream and depth map of any object within one meter of the camera.

The AR0430 is also said to have significant configuration flexibility, which includes the ability to program gain, horizontal and vertical blanking, frame size/rate, exposure, image reversal, window size and panning. Current engineering samples are available in bare die format and full production will start later in 2018.
