Real-time image processing inside a miniature camera using small-package FPGA

Abstract

We present raw image processing pipeline for miniature television camera. This pipeline includes image acquisition over serial interface, dark image subtraction with dynamic temperature variation compensation, image flat-fielding, automatic exposure and gain control. Also this includes a progressive-to-interlaced format conversion, specific to analog signal standards. All of these operations are performed inside small-package 4×4mm Lattice iCELP8K FPGA, placed inside miniature camera.
