PROBLEM TO BE SOLVED: To provide a video signal processing device that can reduce power consumption within an analog signal processing unit, not only during an invalid frame period of a video signal but also during a blanking period within a valid frame period, thus enabling further reduction in power consumption. SOLUTION: The video signal processing device that performs signal processing on an analog video signal inputted from the outside includes an analog signal processing unit 104, including a CDS/AGC unit 101 that samples the analog video signal and amplifies the sampled analog video signal; and an ADC unit 102, that converts the analog video signal outputted from the CDS/AGC unit 101 into a digital video signal, and a timing control unit 105, that controls the analog signal processing unit 104 to switch between operating mode and standby mode.
