Abstract

Relative to an image processing apparatus that processes image data containing a distortion of an image pickup optical section, which is obtained by picking up an optical image from a subject through the image pickup optical section giving the distortion, an image processing apparatus, an image processing method, a program therefor, a recording medium in which the program is recorded, an image pickup apparatus, which are easily used by the user conveniently, are provided. A data output section (13d) outputs the image data of a display image that corresponds to a display mode by using a subject image whose selected region which indicates a part of a field of view represented by the image data is made identifiable and a distortion-corrected image of the selected region. A display mode setting section (13c) performs setting of the display mode. In accordance with switching of the selected region, a control section (13e) changes a first display mode in which the subject image whose selected region is made identifiable is not used in the display image to a second display mode in which the subject image whose selected region is made identifiable is used in the display image.

Claims

1. An image processing apparatus that processes image data containing a distortion of an image pickup optical section, which is obtained by picking up an optical image from a subject through the image pickup optical section giving the distortion, the image processing apparatus comprising:

a data output section that outputs the image data of a display image that corresponds to a display mode by using a subject image whose selected region which indicates a part of a field of view represented by the image data is made identifiable and a distortion-corrected image of the selected region;

a display mode setting section that sets the display mode; and

a control section that, in accordance with switching of the selected region, changes a first display mode in which the subject image whose selected region is made identifiable is not used in the display image to a second display mode in which the subject image whose selected region is made identifiable is used in the display image.

2. The image processing apparatus according to claim 1, wherein in accordance with switching of the selected region, the control section changes the first display mode to the second display mode for a predetermined period of time and changes it to the first display mode after the predetermined period of time elapses.

3. The image processing apparatus according to claim 1, further comprising an input section that performs switchover instruction of the selected region,

wherein the control section switches the selected region in accordance with the switchover instruction.

4. The image processing apparatus according to claim 1, wherein the control section has a first region selection mode in which the selected region moves in an axial direction of an orthogonal coordinate system based on the switchover instruction and a second region selection mode in which the selected region moves in a direction of an argument of a polar coordinate system based on the switchover instruction and, in accordance with switching of the selected region, changes the first display mode to the second display mode.

5. The image processing apparatus according to claim 1, further comprising a direction detection sensor that detects an image pickup direction,

wherein when having determined that the image pickup direction is changed based on a sensor signal from the direction detection sensor, the control section changes the display mode for a predetermined period of time.

6. An image processing method that processes image data containing a distortion of an image pickup optical section, which is obtained by picking up an optical image from a subject through the image pickup optical section giving the distortion, the image processing method comprising:

a data output step of outputting the image data of a display image that corresponds to a display mode by using a subject image whose selected region which indicates a part of a field of view represented by the image data is made identifiable and a distortion-corrected image of the selected region;

a display mode setting step of setting the display mode; and

a display mode changing step of, in accordance with switching of the selected region, changing a first display mode in which the subject image whose selected region is made identifiable is not used in the display image to a second display mode in which the subject image whose selected region is made identifiable is used in the display image.

7. A program that causes a computer to perform image processing to process image data containing a distortion of an image pickup optical section, which is obtained by picking up an optical image from a subject through the image pickup optical section giving the distortion, the program comprising:

a data output step of outputting the image data of a display image that corresponds to a display mode by using a subject image whose selected region which indicates a part of a field of view represented by the image data is made identifiable and a distortion-corrected image of the selected region;

a display mode setting step of setting the display mode; and

a display mode changing step of, in accordance with switching of the selected region, changing a first display mode in which the subject image whose selected region is made identifiable is not used in the display image to a second display mode in which the subject image whose selected region is made identifiable is used in the display image.

8. A recording medium that records a program that causes a computer to perform image processing to process image data containing a distortion of an image pickup optical section, which is obtained by picking up an optical image from a subject through the image pickup optical section giving the distortion, the program comprising:

a data output step of outputting the image data of a display image that corresponds to a display mode by using a subject image whose selected region which indicates a part of a field of view represented by the image data is made identifiable and a distortion-corrected image of the selected region;

a display mode setting step of setting the display mode; and

a display mode changing step of, in accordance with switching of the selected region, changing a first display mode in which the subject image whose selected region is made identifiable is not used in the display image to a second display mode in which the subject image whose selected region is made identifiable is used in the display image.

9. An image pickup apparatus that generates image data containing a distortion of an image pickup optical section, which is obtained by picking up an optical image from a subject through the image pickup optical section giving the distortion and processes the generated image data, the image pickup apparatus comprising:

a data output section that outputs the image data of a display image that corresponds to a display mode by using a subject image whose selected region which indicates a part of a field of view represented by the image data is made identifiable and a distortion-corrected image of the selected region;

a display mode setting section that sets the display mode; and

a control section that, in accordance with switching of the selected region, changes a first display mode in which the subject image whose selected region is made identifiable is not used in the display image to a second display mode in which the subject image whose selected region is made identifiable is used in the display image.
