20220192781 · 2022-06-23 ·

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.
