  • Patent number: 12082773
    Abstract: A control device includes: a power source configured to supply a predetermined power-supply voltage to an imaging element; a voltage detector configured to detect an output voltage value of the power-supply voltage supplied by the power source; and a processor comprising hardware, the processor being configured to supply an adjusted voltage value from the power source to the imaging element based on a voltage value of the power-supply voltage detected in the imaging element and on the output voltage value detected by the voltage detector, calculate a delay time from timing when the voltage value of the power-supply voltage is detected in the imaging element until timing when the power source supplies the adjusted voltage value to the imaging element, and control supply timing when the power source supplies the adjusted voltage value based on the delay time.

  • Publication number: 20240081617
    Abstract: An imaging system includes a camera device and a control device connected to each other by a power source line, a video signal line, and a ground line. An image sensor of the camera device receives, as a distal end voltage, a power source voltage output from the control device to the power source line. An output circuit of the camera device outputs a digital signal indicating a value of the distal end voltage to the video signal line. A calculation circuit of the control device calculates a resistance value of the power source line based on a value of the power source voltage, the value of the distal end voltage indicated by the digital signal, a current value of the power source line, a resistance value of the ground line, and a current value of the ground line.

  • Publication number: 20230156362
    Abstract: An imaging system includes: an imaging unit configured to generate a video signal; a control device configured to control the imaging unit; a first signal line configured to transmit a predetermined power supply voltage to the imaging unit; and a second signal line configured to transmit the video signal to the 284 control device. The imaging unit includes an imaging element including a pixel portion configured to generate the video signal according to a light reception amount and output the generated video signal to the second signal line, and a first detector configured to detect a voltage value of a power supply voltage that has reached the imaging unit via the first signal line as a voltage value of a first power supply voltage and output the voltage value to the second signal line.
