Abstract: A distributed image signal processing (ISP) system for a head-mounted device reduces the power load on the battery of the head-mounted device. The distributed ISP system includes a Bayer image processing engine, an RGB image processing engine, and a YUV image processing engine. The Bayer image processing engine is operated by, for example, processing logic of the head-mounted device. The Bayer image processing engine provides Bayer image data from raw image data. The YUV image processing engine is operated by, for example, processing logic of a (companion) computing device (e.g., a phone, tablet, laptop, compute puck, personal computer). The computing device is communicatively coupled (e.g., wired or wirelessly) to the head-mounted device to receive image data. The RGB image processing engine may be operated by the head-mounted device or the computing device.
