專利摘要(中)
本發明提供一種影像感測器晶片及其感測方法。影像感測器晶片包括像素單元。每一個像素單元包括重置開關、取樣開關、光感測元件、電容以及輸出電路。取樣開關耦接於重置開關與光感測元件之間。電容耦接於取樣開關與輸出電路之間。輸出電路將光感測元件不同幀期間中的多個感測結果之間的差異所對應的差異資訊輸出至對應讀出線。取樣開關在曝光期間中具有導通時間長，以及在讀出與清除期間中具有截止時間長。導通時間長與截止時間長的比例相關於光感測元件的電容值與電容的電容值的比例。

專利摘要(英)
The present invention provides an image sensor chip and a sensing method thereof. The image sensor chip includes pixel units. Each pixel unit includes a reset switch, a sampling switch, a light sensing element, a capacitor and an output circuit. The sampling switch is coupled between the reset switch and the light sensing element. The capacitor is coupled between the sampling switch and the output circuit. The output circuit outputs difference information corresponding to the difference between a plurality of sensing results of the light sensing element in different frame periods to a corresponding readout line. The sampling switch has a ON-time length in an exposure period and an OFF-time length in a readout and clean-up period. The ratio of the ON-time length to the OFF-time length is related to the ratio of the capacitance of the light sensing element to the capacitance of the capacitor.
