| 摘要 | An imaging device includes: an image sensor including pixels and configured to receive light from outside, and generate and output an imaging signal according to an amount of the received light; a transmission cable connected to the image sensor and configured to propagate the imaging signal; a terminating resistor provided at a terminal of the transmission cable, the terminal resistor including an alternating current terminating resistor with variable resistance and a direct current terminating resistor with variable resistance, and having a constant combined resistance of the direct current terminating resistor and the alternating current terminating resistor; and a control unit configured to perform control to make a resistance of the direct current terminating resistor during a blanking period in which the image sensor does not output the imaging signal higher than that during a normal operation period in which the image sensor outputs the imaging signal. | ||
