Claim 9:
10. An image sensing system, comprising:
a control circuit; and
an image sensor, configured to perform:
(a) receiving a first polling from the control circuit by the image sensor at a first polling time;
(b) corresponding to the first polling, triggering a first dummy read at a first dummy read time after the first polling time, to compute output motion delta occurs between the first polling time and the first dummy read time according to at least one frame sensed by the image sensor between the first polling time and the first dummy read time;
(c) receiving a second polling from the control circuit at a second polling time after the first dummy read time; and
(d) outputting the output motion delta to the control circuit in a predetermined time range of the second polling time.
