Claim 18:
19. A non-transitory computer readable recording medium comprising at least one program code recorded therein, an image sensing system control method applied to an image sensing system comprising an image sensor and a control circuit can be performed when the program code is executed, the image sensing system control method comprising:
(a) receiving a first polling at a first polling time and a second polling at a second polling time from the control circuit, wherein the second polling time is after the first polling time;
(b) triggering a first dummy read at a first dummy read time after the first polling time by the image sensor and triggering a second dummy read at a second dummy read time before the first polling time by the image sensor;
(c) corresponding to the first dummy read, computing output motion delta occurs between the first dummy read time and the second dummy read time according to frames sensed by the image sensor between the first dummy read time and the second dummy read time; and
(d) outputting the output motion delta to the control circuit by the image sensor in a predetermined time range the second polling time.
