Abstract: There is provided a pixel circuit for performing analog operation including a photodiode, a first temporal circuit, a second temporal circuit and an operation circuit. Within a first interval, the photodiode detects first light energy to be stored in the first temporal circuit. Within a second interval, the photodiode detects second light energy to be stored in the second temporal circuit. Within an operation interval, the first temporal circuit outputs a first detection signal having a first pulse width according to the first light energy and outputs a second detection signal having a second pulse width according to the second light energy for being calculated by the operation circuit.

Abstract: There is provided a locker with a motion sensor. The motion sensor identifies whether an object is put into or taken out from the locker by calculating coordinates of the object using a motion detection algorithm, by calculating a moving vector of the object using an image time differential algorithm or by comparing a current image frame and a background image frame, and outputs a put-in signal and a taken-out signal to a post control system.
