Image capturing device and image capturing method
An image capturing device includes: an image capturing unit that captures a subject image through a lens and converts the subject image into an electric signal; an image displaying unit that displays an image; a designation accepting unit that is provided on a display surface of the image displaying unit and that accepts designation of a plurality of positions on the image displayed on the image displaying unit; a range-finding unit that performs range finding of a distance to a subject by using a plurality of two-dimensional image sensors; an area setting unit that sets a range-finding area obtained from a range finding result for a region that includes the plurality of positions designated through the designation accepting unit; a position determining unit that determines in-focus positions based on distances of the range-finding areas; and a continuous shooting unit that performs image capturing at the in-focus positions.
1. An image capturing device comprising:
an image capturing unit that captures a subject image through a lens and converts the subject image into an electric signal;
an image displaying unit that displays an image based on the electric signal from the image capturing unit;
a designation accepting unit
that is provided on a display surface of the image displaying unit, and
that accepts designation of a plurality of positions on the image displayed on the image displaying unit;
a range-finding unit that performs range finding of a distance to a subject by using a plurality of two-dimensional image sensors;
an area setting unit that sets a range-finding area obtained from a range finding result that is output from the range-finding unit for a region that includes the plurality of positions designated through the designation accepting unit;
a position determining unit that determines a plurality of in-focus positions of focus areas based on distances of the range-finding areas set by the area setting unit, at least one focus area of the focus areas corresponding to a combination of a plurality of areas having similar distances; and
a continuous shooting unit that performs image capturing at the plurality of the in-focus positions determined by the position determining unit.
2. The image capturing device according to claim 1 , further comprising a face-area detecting unit that detects a face area of the subject, wherein
the area setting unit sets, when the face-area detecting unit has detected a face area, an area that overlaps the detected face area as the range-finding area.
3. The image capturing device according to claim 1 , wherein
the designation accepting unit accepts, at once, designation of a plurality of positions designated by a touch-and-drag operation performed on the designation accepting unit.
4. The image capturing device according to claim 3 , wherein
when a plurality of positions designated by the touch-and-drag operation are accepted by the designation accepting unit, the plurality of the positions are determined by first performing a touch operation that determines a first position, subsequently by performing a drag operation that determines the plurality of the positions so that the plurality of the positions except the first position are included in a track generated by the drag operation, and finally by performing a detach operation that determines a last position.
5. The image capturing device according to claim 1 , wherein
a frame that indicates a focus area in which an in-focus position is to be determined within a region that includes a plurality of positions designated at once through the designation accepting unit from a user is displayed on the image that is displayed on the image displaying unit.
6. The image capturing device according to claim 1 , wherein
the designation accepting unit includes a touch panel.
7. An image capturing method for capturing an image in an image capturing device that includes
an image capturing unit that captures a subject image through a lens and converts the subject image into an electric signal;
an image displaying unit that displays an image based on the electric signal from the image capturing unit;
a designation accepting unit
that is provided on a display surface of the image displaying unit, and
that accepts designation of a plurality of positions on the image displayed on the image displaying unit; and
a range-finding unit that performs range finding of a distance to a subject by using a plurality of two-dimensional image sensors, the image capturing method comprising:
setting, by an area setting unit of the image capturing device, a range-finding area obtained from a range finding result that is output from the range-finding unit for a region that includes the plurality of positions designated through the designation accepting unit;
determining, by a position determining unit of the image capturing device, a plurality of in-focus positions of focus areas based on distances of the range-finding areas set by the area setting unit, at least one focus area of the focus areas corresponding to a combination of a plurality of areas having similar distances; and
performing, by a continuous shooting unit of the image capturing device, image capturing at the plurality of in-focus positions determined by the position determining unit.
8. The image capturing device according to claim 1 , wherein the range-finding unit performs the range finding, without preforming a hill-climbing process.
