STMicroelectronics Targets Always-On Wearables with BrightSense Cameras
STMicroelectronics announced two new BrightSense global-shutter image sensors, the VD55G4 (monochrome) and VD65G4 (RGB), aimed at battery-powered wearables, AR/VR headsets, and compact smart devices, according to the company press release reported by Business Insider Markets. The sensors use a detect-and-wake, event-driven architecture that Business Insider and Hackster report can draw a claimed 1-2mW in low-power monitoring mode and under 35mW when streaming video at 60 frames per second. Both parts offer an 804x704 resolution, 2.16µm pixel pitch, backside illumination, a global shutter, and up to 184 frames per second full-resolution output, per Hackster and the ST press materials. Samples are available to early adopters; pricing has not been disclosed in the press release.
What happened
STMicroelectronics announced two additions to its BrightSense image-sensor family, the `VD55G4` (monochrome) and `VD65G4` (RGB), intended for compact, battery-powered devices. According to STMicroelectronics' press release as reported by Business Insider Markets, the parts target wearables, AR/VR headsets, smart home devices, and medical devices. Hackster's coverage includes a direct quote from Alexandre Balmefrezol: "Always-on vision is becoming essential for the next generation of personal electronics, from smart glasses and AR/VR headsets to intelligent home appliances and medical devices," and notes that samples are available while pricing remains undisclosed.
Technical details
Per the product announcement and technical coverage on Hackster, both sensors feature a global shutter, backside illumination, an 804x704 pixel array, and 2.16µm pixel pitch. The vendor materials report a maximum full-resolution output of 184 frames per second and list interfaces for host connectivity including MIPI CSI-2, SPI, and I3C, with control over I2C or I3C. Power figures quoted in the press materials and trade coverage state that streaming at 60 fps can draw under 35mW, while the on-sensor "sleepy" monitoring mode for event-driven operation draws a claimed 1-2mW.
Scoring Rationale
Notable hardware update: the claimed **1-2mW** event-driven mode and compact global-shutter form factor matter to embedded-vision system designers and wearable OEMs, but this is a component-level advance rather than a platform shift.
