Image Acquiring Apparatus For Vehicle, Control Device, Vehicle Having Image Acquiring Apparatus For Vehicle Or Control Device, And Image Acquiring Method For Vehicle
An image acquiring apparatus for a vehicle includes a light emitting unit configured to emit pulse light to a predetermined direction, an image acquisition unit configured to acquire a plurality of different images of target distance ranges by imaging reflected light returning from the target distance ranges at imaging timings set according to the target distance ranges, and a timing controller configured to control a light emission cycle of the pulse light and the imaging timings. The timing controller is configured to set a light emission interval time to be longer than a delay time which is a time from a light emission start time point of the light emitting unit to an imaging start time point of the image acquisition unit and is required to image a longest-distance range of the target distance ranges from which the reflected light can be imaged.

- 1. An image acquiring apparatus for a vehicle comprising:
a light emitting unit configured to emit pulse light to a predetermined direction; an image acquisition unit configured to acquire a plurality of different images of target distance ranges by imaging reflected light returning from the target distance ranges at imaging timings set according to the target distance ranges; and a timing controller control unit configured to control a light emission cycle of the pulse light and the imaging timings, wherein the timing controller is configured to set a light emission interval time to be longer than a delay time which is a time from a light emission start time point of the light emitting unit to an imaging start time point of the image acquisition unit and is required to image a longest-distance range of the target distance ranges from which the reflected light can be imaged.
- 4. A control device for controlling an image acquiring apparatus for a vehicle,
wherein the vehicle comprises: a light emitting unit configured to emit pulse light to a predetermined direction, and an image acquisition unit configured to acquire a plurality of different images of target distance ranges by imaging reflected light returning from the target distance ranges at imaging timings set according to the target distance ranges, wherein the control device comprises: a controller configured to set a light emission interval time to be longer than a delay time which is a time from a light emission start time point of the light emitting unit to an imaging start time point of the image acquisition unit and is required to image a longest-distance range of the target distance ranges from which the reflected light can be imaged.
- 6. An image acquiring method for a vehicle, comprising:
acquiring a plurality of different images of target distance ranges by imaging reflected light of pulse light emitted to a predetermined direction while changing imaging timings; and setting a light emission interval time representing the light emission cycle of the pulse light to be longer than a delay time which is a time from a light emission start time point of the pulse light to an imaging start time point of the reflected light and is required to image a longest-distance range of the target distance ranges from which the reflected light can be imaged.
