Abstract
A display and imaging device includes a display of a transmissive type configured to receive an image as an input and display the image, a camera configured to image a side in front of the display from behind the display, a distance detecting unit configured to detect a distance from the camera to a target object of imaging using the camera and a depth of field control unit configured to control a depth of field of imaging using the camera in accordance with the detected distance.
Claims7
1:
- A display and imaging device comprising:
- a display of a transmissive type configured to receive an image as an input and display the image;
- a camera configured to image a side in front of the display from behind the display;
- and
- circuitry configured to:
- detect a distance from the camera to a target object of imaging using the camera;
- and
- control a depth of field of imaging using the camera in accordance with the detected distance.
5 more elements
2:
- The display and imaging device according to claim 1, wherein the circuitry sets a focus distance of imaging using the camera that serves as a reference of the depth of field to be longer than the detected distance in accordance with the detected distance.
3:
- The display and imaging device according to claim 1, wherein the circuitry controls the depth of field also in accordance with features of an image acquired through imaging using the camera.
4:
- The display and imaging device according to claim 3, wherein the circuitry controls the depth of field also in accordance with at least one of a type of target object shown in the image acquired through imaging using the camera, a luminance value of the image, and a frequency component of the image.
5:
- The display and imaging device according to claim 3, wherein the circuitry controls the depth of field also in accordance with features of at least one of a part of the image acquired through imaging using the camera in which the target object is shown and a part in which the target object is not shown.
6:
- The display and imaging device according to claim 1, wherein the circuitry detects a position at which the target object is shown in an image acquired through imaging using the camera and detects the distance on the basis of the detected position.
7:
- The display and imaging device according to claim 2, wherein the circuitry controls the depth of field also in accordance with features of an image acquired through imaging using the camera.
