    Abstract: Images to be projected onto a projection surface are modified prior to projection based on color values sampled from the projection surface. A camera samples color values from the projection surface and a processor generates a modified source image based at least in part on pixel color values in an original source image and the color values sampled from the projection surface. A projector then projects the modified source image onto the projection surface.

    Abstract: Described are techniques for establishing video communication between devices while reducing delays associated with initialization of a camera system. When a command from a sender device to initiate a communications session with a recipient device is received, the command may include recipient information indicative of the recipient device. Correspondence between the recipient information and sender contact data may be used determine a recipient profile identifier. Prior to providing a communication request to the recipient device, an initialization command may be provided to the recipient device to cause the recipient device to begin initializing a camera system. Providing the initialization command to the recipient device responsive to the command from the sender device, in advance of the communication request, enables the communications session to be initiated more rapidly than if the recipient device began to initialize the camera system responsive to the communication request.

    Abstract: Described are techniques for establishing communications sessions between devices. A command from a sender device to initiate a communications session with a recipient device may include information indicative of a recipient user profile. Correspondence between recipient information and sender contact data may be used to determine the recipient user profile. Prior to providing a communication request to the recipient device, recipient contact data may be determined using the recipient user profile. Correspondence between the sender user profile and the recipient contact data may be used to determine sender information indicative of the sender. This information may be provided to the recipient device in advance of the communication request to enable more rapid acceptance of the communication request and eliminate the delay that would be incurred if the recipient device determined the sender information responsive to the communication request.
