Abstract

A signal processing apparatus for displaying an input image in the sate in which a part of the image is enlarged, displays an enlarged image obtained by enlarging a part of a designated object in the input image so that the enlarged image is superimposed at a position in accordance with the position of the designated object.

Claims

1. A signal processing apparatus comprising:

an input unit which inputs image data;

a designation unit which designates a first object and a second object in the image data;

a superimposition unit which superimposes a first enlarged image by enlarging a image including a part of the first object and a second enlarged image by enlarging an image including a part of the second object on the image data; and

an output unit which outputs the image data obtained by the superimposition unit to a display apparatus;

wherein, if a positional relationship between the first object and the second object is a predetermined relation, the superimposition unit superimposes one enlarged image by enlarging an image including both a part of the first object and a part of the second object.

2. The signal processing apparatus according to claim 1,

wherein a superimposition position of the one enlarged image is decided on a basis of the position of the first object and the position of the second object.

3. The signal processing apparatus according to claim 1, further comprising,

an enlargement unit which generates an enlarged image in every shape.

4. The signal processing apparatus according to claim 1, further comprising,

an enlargement unit which generates an enlarged image in a predetermined shape selected from among a plurality of shapes.

5. The signal processing apparatus according to claim 1, further comprising,

an enlargement unit which generates an enlarged image by enlarging at least twice an image including a part of an object.

6. A signal processing method comprising:

a designating step of designating a first object and a second object in an input image data;

superimposing a first enlarged image by enlarging a image including a part of the first object and a second enlarged image by enlarging a image including a part of the second object on the image data;

an outputting step of outputting the image data which is superimposed the first enlarged image and the second enlarged image thereon;

wherein, if the positional relationship between the first object and the second object is a predetermined relation, the superimposition step superimposes one enlarged image by enlarging an image including both a part of the first object and a part of the second object.

7. The signal processing method according to claim 6,

wherein the superimposing step superimposes the one enlarged image on the image data, and

wherein a superimposition position of the one enlarged image is decided on a basis of the position of the first object and the position of the second object.

8. The signal processing method according to claim 6, further comprising,

a generating step of generating an enlarged image in every shape.

9. A signal processing apparatus comprising:

an input unit which inputs image data;

a designation unit which designates a first object and a second object in the image data;

a superimposition unit which superimposes a first enlarged image by enlarging a image including a part of the first object and a second enlarged image by enlarging a image including a part of the second object on the image data; and

an output unit which outputs the image data obtained by the superimposition unit to a display apparatus;

an analyzing unit which analyzes an overlapping range of the first enlarged image and the second enlarged image; and

a combining unit which generates a combined image by combining the first enlarged image and the second enlarged image in the overlapping range,

wherein the superimposition unit superimposes the combined image on the image data.

10. The signal processing apparatus according to claim 9, further comprising,

an enlargement unit which generates an enlarged image in every shape.

11. The signal processing apparatus according to claim 9, further comprising,

an enlargement unit which generates an enlarged image in a predetermined shape selected from among a plurality of shapes.

12. The signal processing apparatus according to claim 9, further comprising,

an enlargement unit which generates an enlarged image by enlarging at least twice an image including a part of an object.

13. A signal processing method comprising the steps of:

a designating step of designating a first object and a second object included in an input image data;

a superimposing step of superimposing a first enlarged image by enlarging a image including a part of the first object and a second enlarged image by enlarging a image including a part of the second object on the image data;

an outputting step of outputting the image data which is superimposed the first enlarged image and the second enlarged image thereon;

an analyzing step of analyzing an overlapping range of the first enlarged image and the second enlarged image; and

a generating step of generating a combined image by combining the first enlarged image and the second enlarged image in the overlapping range,

wherein the superimposing step superimposes the combined image generated on the moving image data.

14. An image processing apparatus comprising:

an obtain unit which obtains image data;

a designation unit which designates a first object and a second object in the image data in the image data;

a superimposition unit which superimposes a first enlarged image by enlarging a image including a part of the first object and a second enlarged image by enlarging a image including a part of the second object on the image data; and

a controller which decides a superimposition position of the first enlarged image and the second enlarged image so as not to overlap the first enlarged image and the second enlarged image, in accordance with the position of the first object and the position of the second object.

15. The image processing apparatus according to claim 14, further comprising,

an enlargement unit which generates an enlarged image in every shape.

16. The image processing apparatus according to claim 14, further comprising,

an enlargement unit which generates an enlarged image in a predetermined shape selected from among a plurality of shapes.

17. The image processing apparatus according to claim 14, further comprising,

an enlargement unit which generates an enlarged image by enlarging at least twice an image including a part of an object.

18. A control method for image processing apparatus, said image processing apparatus has an obtain unit which obtains image data, a designation unit which designates a first object and a second object in the image data in the image data, and a superimposition unit which superimposes a first enlarged image by enlarging a image including a part of the first object and a second enlarged image by enlarging a image including a part of the second object on the image data, said method comprising:

deciding a superimposition positions of the first enlarged image and the second enlarged image so as not to overlap the first enlarged image and the second enlarged image, in accordance with the position of the first object and the position of the second object.
