An object of this invention is to simplify an operation of reproducing, on a single window, pieces of image information of different image capturing apparatuses or pieces of image information captured at different times. The cross connector may include multiple rod-stabilization members that simultaneously engage respective rods of a fixation construct. When applied in conventional solar cells, this alternating bias scheme has the potential of more than doubling their yielded net efficiency. The compare circuit may be configured to generate a reset signal in response to each of the output signals.
