Abstract: In example implementations, an apparatus includes a camera, an image signal processor and a display processor. The camera measures metered values of an image projected onto a surface. The image signal processor is in communication with the camera to receive the metered values of the image on the surface. Display parameters are calculated by the image signal processor based on the metered values of the image on the surface that is measured. The display processor is in communication with the image signal processor and a projector. The display processor generates a color corrected image projected onto the surface by the projector. The color corrected image is generated based on the display parameters.

Abstract: Example implementations relate to peripheral device operation. For example, a peripheral device may include a processor. The processor may detect that a computing device is in communication with the peripheral device and send peripheral device information to the computing device. The peripheral device information may specify characteristics associated with the peripheral device including a purpose, capability, and context of the peripheral device. The processor may receive operational data from the computing device, where the operational data may be based on the peripheral device information and may indicate a manner of operating the peripheral device. The processor may perform an operation based on the operational data.
