Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: An apparatus of serializer/deserializer is provided. The apparatus comprises a holding unit and a capture unit. The holding unit connects to the capture unit through a coaxial cable, and comprises a disposable image-capture module, a synthetic-image module (L/R montage), a Mipi serializer, a Mipi deserializer, a Mipi capture card, and a capture device. Thus, the apparatus keeps the most expensive ISP and capture device at a back end; and puts the disposable image-capture module, the synthetic-image module, and the Mipi serializer at a front end. After use, it is only necessary to discard the disposable image-capture module, which extends into human body at the front end. The remaining parts are reused. Thus, cost is effectively reduced and the shortcoming of high cost of the use of modern disposable endoscope is solved.

Abstract: The present invention has two antennas to receive video/audio signals. The antennas tunes the frequency bands of the signals they receive in order to display two video/audio signals of two different bands. Or, if the antennas are tuned to receive video/audio signals of the same frequency band, the sensitivity on receiving signals is enhanced.
