Cell phone reading mode using image timer

摘要

An system contains an image capture device configured to capture an image. The system includes a lighting and exposure mechanism. The system also includes a camera sensor interface with a stat FIFO. The stat FIFO is configured to receive data from the image capture device. When the stat FIFO, during image scanning, receives a pre-determined amount of image data, it fires an interrupt, which times the lighting and exposure mechanism in the system.

1. A system, comprising:
an image capture device configured to capture an image and transmit image data, the image capture device comprising a lighting and exposure mechanism; and a camera sensor interface configured to receive image data from the image capture device, the camera sensor interface comprising a stat FIFO; wherein the stat FIFO is configured to:
receive image data from the image capture device; andresponsive to receiving a pre-determined portion of the image data, send an interrupt to the lighting and exposure mechanism; wherein the lighting and exposure mechanism, responsive to receiving the interrupt, turns on and off; and wherein the pre-determined portion of the image data is determined by defining a threshold number of pixels per image block in the stat FIFO.
