Abstract
An image sensing apparatus comprises at least one sensing pixel and a control circuit. The sensing pixel comprises: a charge storing device; a light sensing device, for respectively generating photoelectrons with a first, second amount in a first, second mode; and a switch device, for determining an amount that the photoelectron 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 photoelectrons 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.
