Image overlay in a mobile device

摘要

Image overlay in a mobile device is described. In one embodiment an imaging system of a mobile communications device includes a first camera having a control interface to a controller and a data interface to the controller, a second camera having a data interface to the first camera, and a processor to combine an image from the second camera received through the second camera data interface with an image from the first camera and to send the combined image to the controller through the data interface.

主权项

1. An imaging system of a mobile communications device comprising:
a first camera configured to capture first image data; a second camera configured to capture second image data, wherein the first camera is coupled to receive the second image data via a first data interface coupled between the first camera and the second camera, and wherein the second camera is a slave to the first camera; and a processor comprising an overlay combination block coupled to receive the first image data and the second image data from the first camera, wherein the overlay combination block is configured to form a combined image using the first image data and the second image data received from the first camera, the processor being integrated with the first camera, wherein the first camera is a slave to the processor, and wherein the processor is coupled to send the combined image to a controller through a second data interface that is different from the first data interface, wherein the first camera includes a decoder coupled to receive the second image data from the second camera and decompress and decode the second image data into raw image data.
