1. An EIR terminal comprising:
- an image capture device configured to scan an image;
wherein said image capture device comprises a lighting and exposure mechanism;
a camera sensor interface configured to receive data from said image capture device,wherein said camera sensor comprises a stat FIFO,wherein said stat FIFO is configured to receive image data from said image capture device,wherein said stat FIFO is configured, responsive to receiving a pre-determined portion of said image data, to send an interrupt to said lighting and exposure mechanism;
wherein said lighting and exposure mechanism, responsive to receiving said interrupt, turns on and off; and
wherein said interrupt is configured by vertical blank timing in said CSI.

Abstract
An EIR terminal containing an image capture device configured to scan an image. The EIR terminal includes a lighting and exposure mechanism. The EIR terminal 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 EIR terminal.

8. A method of utilizing a stat FIFO in an EIR terminal to manage lighting and exposure during cell phone reading mode, said method comprising:
-
allocating blocks in said stat FIFO to receive image data when said EIR terminal is utilized to scan an image, wherein said stat FIFO is located in a CSI of said EIR terminal; configuring said stat FIFO to receive a given number of pixels of said image data per each of said blocks; configuring said stat FIFO to provide an interrupt each time said given number of pixels of image data is received by said stat FIFO, wherein said interrupt instructs a lighting and exposure mechanism to turn on or off; utilizing vertical blank timing in said CSI to time said lighting and exposure mechanism; and scanning said image. - View Dependent Claims (9, 10, 11, 12)
