Image capture device and image capture method

An image capture device with multiple image capture units, the image capture device comprising:

• one light emission unit for distance measurement that emits a reference beam;
• the multiple image capture units that capture images of a reflected beam of the reference beam while having common timing of image capture;
• and
• a sensor control unit that outputs a light emission timing signal and an image capture timing signal, wherein
• the light emission unit emits the reference beam based on the light emission timing signal input from the sensor control unit,
• each of the multiple image capture units captures an image based on the image capture timing signal input from the sensor control unit, and
• an output unit or an input unit that outputs or inputs the light emission timing signal and/or the image capture timing signal, and comprises a phase shifter which controls deviation in timing between the light emission timing signal and the image capture timing signal due to differences or changes in characteristics of components.

An image capture method implemented by an image capture device with multiple image capture units including one light emission unit for distance measurement that emits a reference beam and the multiple image capture units that capture images of a reflected beam of the reference beam while having common timing of image capture, the multiple image capture units including a first image capture unit as a master and a second image capture unit as a slave, the method comprising:

• a control unit for the first image capture unit outputting a light emission timing signal to the light emission unit and outputs an image capture timing signal to a control unit for the second image capture unit,
• the light emission unit emitting a beam based on the light emission timing signal input from the control unit for the first image capture unit,
• the second image capture unit capturing an image based on the image capture timing signal input from the control unit for the first image capture unit, and
• an output unit or an input unit that outputs or inputs the light emission timing signal and/or the image capture timing signal, and including a phase shifter for controlling deviation in timing between the light emission timing signal and the image capture timing signal due to differences or changes in characteristics of components.
