According to the optical-electric properties of liquid crystal, an eye controlled focus (ECF) anti-glare imaging detector is designed. Considering the existed concept of point metering controlled by the eye, a new concept of photometry, point-by-point single-pixel metering controlled by the eye, is brought forward. The method of ECF in the detector is researched. Firstly the pupil’s image is attained, and then the detector focuses with the focused function. Besides, a distinct image and a vague one are processed. The focused function values of the two images are 8.5057×103 and 7.2381×103 respectively.
