a second optical module and a second image sensor disposed corresponding to the second optical module; wherein the second optical module is adapted to capture another image in a second field-of-view to project the another image on the second image sensor, such that the second image sensor generates a second image frame; wherein the vertical resolution of the second image frame is Y3 while the horizontal resolution of the second image frame is X3;

wherein the first optical module and the second optical module are arranged in parallel to a longitudinal direction, and the vertical resolutions of the first image frame and the second image frame correspond to the longitudinal direction; and

a data processing circuit, electrically connected to the first image sensor and the second image sensor; wherein the data processing circuit is adapted to merge the first image frame and the second image frame in the longitudinal direction to generate a combined image frame; wherein the vertical resolution of the combined image frame is Y1, the horizontal resolution of the combined image frame is X1; and Y1>X1;

wherein relation between the vertical resolutions and the horizontal resolutions is expressed by a mathematical formula:
