Abstract

An imaging apparatus include an imaging processing unit, a dial operation unit, a boundary setting unit, and a control unit. The imaging processing unit acquires image data having a predetermined image effect. The dial operation unit receives a dial operation to set at least one boundary line in the image data. The boundary setting unit sets the boundary line in the image data in response to the dial operation. The control unit controls the imaging processing unit so that image data having different image effects are obtained in the respective partial regions of the image data that are divided by the boundary line set by the boundary setting unit.

Claims

1. An imaging apparatus comprising:

an imaging processing circuit which acquires image data having a predetermined image effect;

an operation dial which receives a dial operation to set at least one boundary line in the image data;

a boundary setting circuit which sets the boundary line in the image data in response to the dial operation;

a controller which controls the imaging processing circuit so that image data having different image effects are obtained in the respective partial regions of the image data that are divided by the boundary line set by the boundary setting circuit and

a display which displays a central point, segments radially extending from the central point, and boundary line constituent points which are points on the segments and which constitute the boundary line when the boundary line constituent points are connected to one another,

wherein the operation dial includes a first operation dial which receives a dial operation to set positions of the boundary line constituent points, and

the boundary setting circuit sets the position of the boundary line in response to the dial operation of the first operation dial.

2. The imaging apparatus according to claim 1, wherein the operation dial includes a third operation dial which receives a dial operation to set a correction factor of the image effect for each of the partial regions, and

the imaging processing circuit acquires the image data in accordance with the correction factor.

3. The imaging apparatus according to claim 1, wherein the boundary line forms a closed region, and

the controller controls the imaging processing circuit so that image data having different image effects are obtained in the respective partial regions inside and outside the closed region.

4. The imaging apparatus according to claim 1, wherein the operation dial includes a second operation dial which receives a dial operation to select one of the segments, and

the first operation dial receives a dial operation to set a position of the boundary line constituent point on the segment selected by the dial operation of the second operation dial.

5. The imaging apparatus according to claim 1, further comprising a first operation control which receives an operation to switch between a point selection mode and a segment selection mode, the point selection mode being designed to receive a dial operation by the first operation dial to set the position of the boundary line constituent point, the segment selection mode being designed to receive a dial operation by the first operation dial to select one of the segments.

6. The imaging apparatus according to claim 1, further comprising a second operation control which receives an operation to change a position of the central point.

7. The imaging apparatus according to claim 6, wherein the boundary setting circuit changes the position of the boundary line while maintaining a shape of the boundary line in response to the operation of the second operation control.

8. The imaging apparatus according to claim 1, wherein the boundary setting circuit has a size changing mode to change a size of a region surrounded by the boundary line while maintaining a shape of the boundary line in response to the dial operation of the first operation dial,

the imaging apparatus further comprising a third operation control which receives an operation to switch to the size changing mode.

9. The imaging apparatus according to claim 1, wherein the image effect includes at least one of a brightness correction, a contrast correction, a highlight and shadow correction, a white balance correction, and a hue and saturation correction in the image data.

10. A control method of an imaging apparatus comprising:

receiving a dial operation by a operation dial to set at least one boundary line in image data;

setting the boundary line in the image data in response to the dial operation;

controlling an imaging processing unit so that image data having different image effects are obtained in the respective partial regions of the image data that are divided by the set boundary line; and

displaying a central point, segments radially extending from the central point, and boundary line constituent points which are points on the segments and which constitute the boundary line when the boundary line constituent points are connected to one another,

wherein the operation dial receives a dial operation to set positions of the boundary line constituent points, and

the position of the boundary line is set in response to the dial operation of the operation dial.

11. A computer-readable non-transitory storage medium to record a program to cause a computer to:

receive a dial operation by a operation dial to set at least one boundary line in image data;

set the boundary line in the image data in response to the dial operation;

control an imaging processing unit so that image data having different image effects are obtained in the respective partial regions of the image data that are divided by the set boundary line; and

display a central point, segments radially extending from the central point, and boundary line constituent points which are points on the segments and which constitute the boundary line when the boundary line constituent points are connected to one another,

wherein the operation dial receives a dial operation to set positions of the boundary line constituent points, and

the position of the boundary line is set in response to the dial operation of the operation dial.
