A low-power image capture device includes a first image buffer in SRAM coupled to receive images from an image sensor, and a second image buffer receiving images transferred in bursts from the first image buffer, the second image buffer implemented in PASR DRAM, the image buffers together operating as a first-in, first-out, (FIFO) buffer. The device includes an activation detector. The PASR DRAM is powered while receiving bursts of images from the first image buffer, and when the image capture device is in the activated mode; and in ultra-low power PASR mode otherwise. A method includes capturing images into the first image buffer, transferring the images in bursts into a second image buffer in PASR DRAM powered while receiving the images in bursts, the PASR DRAM otherwise in ultra-low power PASR mode; and, upon activating, an image processor receiving images from the second image buffer.

Camera system with PWM-activated, burst-self-refresh, DRAM to reduce standby power consumption

A 360 degree camera system includes a support structure, a plurality of image capture devices, a plurality of lens systems, and an image processing system. The image capture devices are positioned such that their height is greater than their width. The image processing system includes a rotation module for remapping the pixel addresses of the image data to join the captured images along their long edges.
