自动亮度控制硬件系统作为设计的另一个环节，利用FPGA完成了峰值测光与区域测光的设计。

The automatic brightness control system is another design. The design includes the average and peak area exposure measurement using FPGA.

佳能的E - TTL II甚至可以测出相机和主要被摄对象间的距离并将此作为测光的考虑因素之一。

Canon's E-TTL II even measures the distance to the main subject and that also becomes part of the evaluation taking place.
