Abstract
A camera is disclosed which includes: at least two image sensors, an image sensor selector, a multiplexer and an image processor. The at least two image sensors are configured to synchronously output successive pixels of image data. The image sensor selector is responsive to a pan and/or tilt signal input associated with a target view of the image data provided by the at least two image sensors, to output a select signal indicating for each synchronous output of pixels from the at least two image sensors a selected one of the at least two image sensors delivering a pixel within the target view. The multiplexer has inputs, an output, and a control input. The multiplexer inputs are each coupled to a corresponding one of the at least two image sensors to receive the successive pixels of image data there from. The multiplexer is responsive to the select signal from the image sensor selector at the control input to output the selected one of the pixels at the input which is within the target view during each pixel clock cycle. The image processor has an input coupled to the output of the multiplexer for processing the pixels within the target view.
