    摘要: An endoscope includes: a CCD that picks up an image of a subject; an FPGA that is controlled by a main body portion 3 to output a drive signal for driving the CCD and transmits an image pickup signal outputted from the CCD to the main body; rewritable flash memory in which at least one of program data and setting data that relate to an operation of the FPGA is stored; and a switch group that, based on a rewriting instruction signal SW to the data in the flash memory, switches so that the data received by using all or a part of signal lines for the CCD, the lines being associated with observation of the subject, is inputted to the flash memory.

    摘要: An impedance matching apparatus includes: a cable that transmits a rectangular wave outputted from a solid image pickup device; a correlated double sampling circuit that performs scanning of the rectangular wave by sampling the rectangular wave with a timing of a signal clamp pulse being changed, based on a timing of the feed-through sampling pulse fixed at a timing at which the rectangular wave by the cable indicates a high value; a variable resistance provided at a tail end side of the cable; and a resistance value varying unit that, that performs the scanning with a resistance value of the variable resistance being changed, based on a signal outputted from the correlated double sampling circuit, changes a resistance value of the variable resistance so as to match a characteristic impedance of the cable.
