OSRAM Color Sensor for Smartphone Cameras
OSRAM’s new TCS3530 color sensor enables smartphone cameras to reach near-perfect color quality in any lighting condition. The company claims that the sensor can reproduce the colors you see in your camera. It also has fully integrated optical assembly, helping simplify production operations for smartphone, camera, and display manufacturers.
The TCS3530 achieves near color perfection by producing an XYZ tri-stimulus response, meaning its three-channel output closely resembles the response of the average human eye’s three sets of color-sensitive light receptors. The sensor’s chip converts the XYZ light measurements to chromaticity coordinates precisely located in CiE color space. This allows for ultra-accurate, automatic white balancing in cameras, resulting in natural rendition of object colors in all conditions.
The sensor’s 8-channel configuration consists of the XYZ channels, an infrared channel, and four reference channels. High-speed flicker detection capability ranging up to 7 kHz works to eliminate light flickering interference when taking video and pictures. It also includes a built-in diffuser, so manufacturers don’t have to design and build an optical assembly with an external diffuser. The sensor is thinner, too, making it easier for smartphone manufacturers to incorporate it in ultra-compact product designs.
