摘要

一种影像感测装置，包含感测像素以及控制电路。感测像素包含：电荷储存元件；光感应元件，分别在第一、第二模式下产生具第一、第二光感应电荷数量的光感应电荷；以及开关元件，根据控制电压决定该光感应电荷能传送至该电荷储存元件的电荷数量。控制电路产生该控制电压，使得该第一模式下该光感应电荷能传送至该电荷储存元件的电荷数量为一第一电荷数量，而该第二模式下该光感应电荷能传送至该电荷储存元件的电荷数量为一第二电荷数量，其中该第一电荷数量和该第二电荷数量均小于该电荷储存元件的最大电荷储存数量。; a light sensing device, for respectively generating light sensing charges with a first, second light sensing charge amount in a first, second mode; and a switch device, for determining an amount that the light sensing charge can be transmitted to the charge storing device according to a control voltage. The control voltage generates the control voltage to control the amount that the light sensing charge can be transmitted to the charge storing device to be a first charge amount in a first mode and to be a second charge amount in a second mode. The first, second charge amounts are smaller than a maximum charge storing amount for the charge storing device.
