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

16. The signal processing apparatus according to claim 15,

wherein the superimposition unit superimposes the one enlarged image on the image data in place of the first enlarged image and the second enlarged image, and

wherein the controller controls the superimposition unit so as to decide a superimposition position of the one enlarged image on a basis of the position of the first object and the position of the second object.

17. The signal processing apparatus according to claim 15,

wherein the enlargement unit generates an enlarged image in every shape.

18. The signal processing apparatus according to claim 15,

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

19. The signal processing apparatus according to claim 15,

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

20. A signal processing method comprising the steps of:

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

detecting a position of the first object and a position of the second object in the image data;

generating a first enlarged image by enlarging an image including a part of the first object and a second enlarged image by enlarging an image including a part of the second object;

superimposing the first enlarged image and the second enlarged image on the image data;

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

deciding a superimposition position of the first enlarged image in accordance with the position of the first object and a superimposition position of the second enlarged image in accordance with the position of the second object,

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

21. The signal processing method according to claim 20,

wherein the superimposing step superimposes the one enlarged image on the image data in place of the first enlarged image and the second enlarged image, and

wherein the deciding step decides a superimposition position of the one enlarged image on a basis of the position of the first object and the position of the second object.

22. The signal processing method according to claim 20,

wherein the generating step generates an enlarged image in every shape.

23. 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 detection unit which detects a position of the first object and a position of the second object in the image data;

an enlargement unit which generates a first enlarged image by enlarging an image including a part of the first object and generates a second enlarged image by enlarging an image including a part of the second object;

a superimposition unit which superimposes the first enlarged image and the second enlarged image on the image data;

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

a controller which controls the superimposition unit so as to decide a superimposition position of the first enlarged image in accordance with the positions of the first object and decide a superimposition position of the second enlarged image in accordance with the position of the second object;

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.

24. The signal processing apparatus according to claim 23,

wherein the enlargement unit generates an enlarged image in every shape.
