Image capture device, player, system, and image processing method
View Patent ↗A system of the present disclosure comprises a shooting system and a playback system. The shooting system includes first and second shooting sections and a disparity calculating section that generates a differential image representing a difference between first and second images that have been shot by the first and second shooting sections, respectively. The playback system includes an image generating section that generates, based on the differential image and the first image, a third image that has as high a resolution as the first image and that forms, along with the first image, a 3D image. The image generating section generates, based on the first image and the differential image, a depth map representing the amount of parallax between the first and second images, and generates the third image based on the first image and the depth map.
1. A system comprising a shooting system with a plurality of shooting sections and a playback system configured to generate a 3D image based on a signal supplied from the shooting system, wherein the shooting system includes:
first and second shooting sections, each of which is configured to shoot an image of a subject;
a disparity calculating section configured to generate a differential image representing a difference between first and second images that have been shot by the first and second shooting sections, respectively; and
an image output section configured to output the first image and the differential image, and
wherein the playback system includes an image generating section configured to get the first image and the differential image and generate, based on the differential image and the first image, a third image that has as high a resolution as the first image and that forms, along with the first image, a 3D image, and
wherein the image generating section generates, based on the first image and the differential image, a depth map representing the amount of parallax between the first and second images, and also generates the third image based on the first image and the depth map,
wherein the image generating section is controlled to determine whether or not to generate the third image based on at least one of a zoom power during shooting and the roll angle of the image capture of device during shooting.
2. The system of claim 1 , wherein the image generating section corrects the depth map according to a viewer's attribute or a viewing environment, and generates the third image based on the depth map corrected and the first image.
3. The system of claim 1 , wherein the disparity calculating section generates a differential image that has a lower resolution than the first image, based on the first and second images.
4. The system of claim 1 , wherein the first shooting section has an optical zoom function and the second shooting section does not have an optical zoom function.
5. The system of claim 1 , wherein the second shooting section has a larger number of pixels than the first shooting section.
6. The system of claim 1 , wherein the second shooting section has a smaller aperture than the first shooting section.
7. The system of claim 1 , wherein the shooting system further includes:
an angle of view matching section configured to match the respective angles of view of the first and second images to each other; and
a number of pixels matching section configured to match the respective numbers of pixels of the first and second images to each other,
wherein the disparity calculating section generates the differential image based on the first and second images that have had their angles of view and numbers of pixels matched to each other by the angle of view matching section and the number of pixels matching section, respectively.
8. The system of claim 1 , wherein if the depth value indicated by the depth map is greater than a predetermined value, the image generating section corrects the depth value indicated by the depth map into a value that is smaller than the predetermined value.
9. A image capture device comprising a shooting system for use in the system of claim 1 .
10. A player comprising a playback system for use in the system of claim 1 .
11. An image processing method comprising the steps of:
(A) getting a first image and a second image;
(B) generating a differential image representing a difference between the first and second images; and
(C) generating, based on the differential image and the first image, a third image that has as high a resolution as the first image and that forms, along with the first image, a 3D image,
wherein the step (C) includes the steps of:
generating, based on the first image and the differential image, a depth map representing the amount of parallax between the first and second images; and
generating the third image based on the first image and the depth map,
wherein whether the third image is generated or not is determined based on at least one of a zoom power during shooting and the roll angle of the image capture device during shooting.
12. The image processing method of claim 11 , wherein the step (C) includes the steps of:
correcting the depth map according to a viewer's attribute or a viewing environment, and
generating the third image based on the depth map corrected and the first image.
