Abstract
Devices, systems and methods are disclosed for discontinuously capturing and transmitting images from a camera. The camera initializes and powers down on-demand components, awaiting a signal on an interrupt pin. Upon receiving a signal on the interrupt pin, the camera powers up the on-demand components, captures a series of images and transmits the series of images. The discontinuous transmission of images allows the camera to reduce a power consumption and a memory usage while reducing a latency between a capture request and the transmission of images.
