1. A driving method to drive an image sensor, wherein the image sensor comprises a plurality of gate line groups and a plurality of drivers respectively corresponding to the gate line groups, wherein each of the gate line groups comprises a plurality of gate lines, wherein each of the drivers is configured to provide control signals to gate lines comprised in a corresponding one of the gate line groups, wherein the driving method comprising:
during a normal scan period under a high frame rate mode, providing a plurality of first control signals generated by a part of the drivers according to a first clock rate to a plurality of target gate lines comprised in a part of the gate line groups; and
during a high speed scan period under the high frame rate mode, providing a plurality of second control signals generated by the part of the drivers according to a second clock rate to a plurality of residual gate lines comprised in the part of the gate line groups, wherein the first clock rate is less than the second clock rate, and wherein the driving method further comprises one of following steps:
during the high speed scan period under the high frame rate mode, providing a plurality of third control signals generated by the other part of the drivers according to the second clock rate to a plurality of residual gate lines comprised in the other part of the gate line groups; or
during a refresh period under the high frame rate mode, providing the third control signals at an enable level generated by the other part of the drivers to the residual gate lines comprised in the other part of the gate line groups.
