Abstract

An illumination apparatus illuminates probe light. A gating camera captures an image for each of image capture ranges divided in the depth direction. A camera controller controls a timing at which the illumination apparatus illuminates the probe light and a timing at which an image sensor is exposed such that each slice image output from the image sensor for each image capture range includes only an object included in the corresponding image capture range while changing the image capture range. An image processing unit generates a final image including the entire object of interest based on the multiple slice images that correspond to the multiple image capture ranges.

Claims (43)

1. A gating camera comprising:

an illumination apparatus configured to illuminate probe light;

an image sensor;

a camera controller configured to control a timing at which the illumination apparatus illuminates the probe light and a timing at which the image sensor is exposed, such that the image sensor outputs a slice image for each of image capture ranges divided in the depth direction while changing the image capture range, and such that each slice image includes only an object included in the corresponding image capture range; and

one or more processors configured to generate a final image including an entire object of interest based on the plurality of slice images that correspond to the plurality of image capture ranges

wherein the final image includes only the object of interest.

2. The gating camera according to claim 1 , wherein the one or more processors is further configured to combine the plurality of slice images so as to generate a combined image, each pixel of which indicates distance information, and to extract a region including the object of interest from the combined image.

3. A gating camera comprising:

an illumination apparatus configured to illuminate probe light;

an image sensor;

a camera controller configured to control a timing at which the illumination apparatus illuminates the probe light and a timing at which the image sensor is exposed, such that the image sensor outputs a slice image for each of image capture ranges divided in the depth direction while changing the image capture range, and such that each slice image includes only an object included in the corresponding image capture range; and

one or more processors configured to combine the plurality of slice images that correspond to the plurality of image capture ranges so as to generate a combined image, each pixel of which indicates distance information.

4. An automobile comprising:

the gating camera according to claim 1 ; and

a calculation processor configured to process an output of the gating camera.

5. An automotive lamp comprising the gating camera according to claim 1 .

6. An image processor for a gating camera,

wherein the gating camera comprises:

an illumination apparatus configured to illuminate probe light;

an image sensor; and

a camera controller configured to control a timing at which the illumination apparatus illuminates the probe light and a timing at which the image sensor is exposed, such that the image sensor outputs a slice image for each of image capture ranges divided in the depth direction while changing the image capture range, and such that each slice image includes only an object included in the corresponding image capture range, and

wherein the image processor is configured to extract slice images including an object of interest from among the plurality of slice images that correspond to the plurality of image capture ranges, and to combine the extracted slice images so as to generate a final image.

7. An image processing method employed in a gating camera, wherein the gating camera comprises:

an illumination apparatus configured to illuminate probe light;

an image sensor; and

a camera controller configured to control a timing at which the illumination apparatus illuminates the probe light and a timing at which the image sensor is exposed, such that the image sensor outputs a slice image for each of image capture ranges divided in the depth direction while changing the image capture range, and such that each slice image includes only an object included in the corresponding image capture range,

wherein the image processing method comprises:

extracting slice images including an object of interest from among the plurality of slice images that correspond to the plurality of image capture ranges; and

combining the extracted slice images so as to generate a final image.

8. An image processor for a gating camera,

wherein the gating camera comprises:

an illumination apparatus configured to illuminate probe light;

an image sensor; and

a camera controller configured to control a timing at which the illumination apparatus illuminates the probe light and a timing at which the image sensor is exposed, such that

the image sensor outputs a slice image for each of image capture ranges divided in the depth direction while changing the image capture range, and such that each slice image includes only an object included in the corresponding image capture range,

and wherein the image processor is configured to combine the plurality of slice images that correspond to the plurality of image capture ranges so as to generate a combined image, each pixel of which indicates distance information.

9. An image processing method employed in a gating camera, wherein the gating camera comprises:

an illumination apparatus configured to illuminate probe light;

an image sensor; and

a camera controller configured to control a timing at which the illumination apparatus illuminates the probe light and a timing at which the image sensor is exposed, such that the image sensor outputs a slice image for each of image capture ranges divided in the depth direction while changing the image capture range, and such that each slice image includes only an object included in the corresponding image capture range,

and wherein the image processing method comprises combining the plurality of slice images that correspond to the plurality of image capture ranges so as to generate a combined image, each pixel of which indicates distance information.

10. The gating camera according to claim 1 , wherein the output slice images for the image capture ranges include a plurality of objects, and

wherein the final image includes only the object of interest from the plurality of objects.
