Abstract
An imaging apparatus comprising: an image acquisition unit configured to acquire an image; a depth map acquisition unit configured to acquire a first depth map; a working range map generation unit configured to generate a working range map showing a working range in the image on the basis of the first depth map; a synthesizing unit configured to synthesize the image and the working range map and to generate a synthesized image; and a display unit configured to display the synthesized image.
Claims15
An image processing apparatus comprising:
- an image acquirer configured to acquire an image of an object;
- a depth map acquirer configured to acquire a first depth map, wherein the first depth map indicates depth information of the object;
- a working range map generator configured to generate a working range map on the basis of the first depth map;
- a synthesizer configured to synthesize the image and the working range map and to generate a synthesized image;
- a display controller configured to display the synthesized image on a display device;
- and
- a parameter changer configured to change a parameter for depth map acquisition used by the depth map acquirer based on a change in a depth map working range,
- wherein the parameter for depth map acquisition includes an F-number and a focus bracket amount,
- wherein the working range map is a map for distinguishing between an area where depth information of the object is within a measurable range and an area where depth information of the object is not within the measurable range, and the working range map is determined on the basis of a parameter for depth map acquisition, and
- wherein the parameter changer is configured to (1) change the F-number if a degree of the change in the depth map working range is greater than a predetermined threshold value, and (2) change the focus bracket amount if the degree of the change in the depth map working range is less than or equal to the predetermined threshold value.
A method of controlling an image processing apparatus, comprising:
- an image acquiring step of acquiring an image of an object;
- a first depth map acquiring step of acquiring a first depth map, wherein the first depth map indicates depth information of the object;
- a working range map generating step of generating a working range map showing a working range in the image on the basis of the first depth map;
- a synthesizing step of synthesizing the image and the working range map and generating a synthesized image;
- a displaying step of displaying the synthesized image on a display device;
- and
- a parameter changing step of changing a parameter for depth map acquisition based on a change in a depth map working range,
- wherein the working range map is a map for distinguishing between an area where depth information of the object is within a measurable range and an area where depth information of the object is not within the measurable range, and the working range is determined on the basis of a parameter for depth map acquisition,
- wherein the parameter for depth map acquisition includes an F-number and a focus bracket amount, and
- wherein, in the parameter changing step, (1) the F-number is changed if a degree of change in the depth map working range is greater than a predetermined threshold value, and (2) the focus bracket amount is changed if the degree of change of the depth map working range is less than or equal to the predetermined threshold value.
A non-transitory computer-readable medium, storing a program allowing a computer to execute each step of a method of controlling an image processing apparatus, the method comprising:
- an image acquiring step of acquiring an image of an object;
- a first depth map acquiring step of acquiring a first depth map, wherein the first depth map indicates depth information of the object;
- a working range map generating step of generating a working range map showing a working range in the image on the basis of the first depth map;
- a synthesizing step of synthesizing the image and the working range map and generating a synthesized image;
- a displaying step of displaying the synthesized image on a display device;
- and
- a parameter changing step of changing a parameter for depth map acquisition based on a change in a depth map working range,
- wherein the working range map is a map for distinguishing between an area where depth information of the object is within a measurable range and an area where depth information of the object is not within the measurable range, and the working range is determined on the basis of a parameter for depth map acquisition,
- wherein the parameter for depth map acquisition includes an F-number and a focus bracket amount, and
- wherein, in the parameter changing step, (1) the F-number is changed if a degree of change in the depth map working range is greater than a predetermined threshold value, and (2) the focus bracket amount is changed if the degree of change in the depth map working range is less than or equal to the predetermined threshold value.
