Abstract

Sensed image data are stored in a memory. Image data of a plurality of images associated with each other out of the stored image data are detected on the basis of a predetermined condition. The image data of the plurality of detected images are processed into image data of a predetermined display size. The same portion of the processed image data is extracted from each of the plurality of images. The extracted portions of the image data of the plurality of images are displayed on the same screen.

Claims

1. An image display apparatus comprising:

a memory adapted to store sensed image data;

a detection unit adapted to detect image data of a plurality of images associated with each other on the basis of a predetermined condition out of the image data stored in said memory;

a processing unit adapted to process the image data of the plurality of images detected by said detection unit into image data of a predetermined display size;

an extraction unit adapted to extract same portions of the image data of the plurality of images processed by said processing unit; and

a display unit adapted to display the portions of the image data of the plurality of images extracted by said extraction unit on the same screen.

2. The apparatus according to claim 1, wherein said extraction unit extracts a central region of the image data processed by said processing unit for each image.

3. The apparatus according to claim 1, wherein said extraction unit extracts a predetermined longitudinal divided region of the image data processed by said processing unit for each image.

4. The apparatus according to claim 1, wherein said extraction unit extracts a predetermined lateral divided region of the image data processed by said processing unit for each image.

5. The apparatus according to claim 1 further comprising a selection unit adapted to select a region of the image data to be extracted by said extraction unit,

wherein said extraction unit extracts image data of the region selected by said selection unit.

6. The apparatus according to claim 1, wherein the plurality of associated images include a series of successively sensed images.

7. The apparatus according to claim 1, wherein the plurality of associated images include a series of images sensed successively while changing an exposure.

8. The apparatus according to claim 1, wherein said extraction unit determines an extraction region from each image data processed by said processing unit, in accordance with the number of associated images.

17. A computer-readable recording medium wherein the medium records a program for causing a computer to function as each of said units defined in claim 1.

19. An image sensing apparatus comprising the image display apparatus defined in claim 1.

9. An image display control method comprising the steps of:

detecting image data of a plurality of images associated with each other, on the basis of a predetermined condition, out of image data stored in a memory adapted to store sensed image data;

processing the image data of the plurality of detected images into image data of a predetermined display size;

extracting same portions of the processed image data of the plurality of images; and

displaying the portions of the image data of the plurality of extracted images on the same screen.

10. The method according to claim 9, wherein, upon extracting the portions of the image data, a central region of the processed image data are extracted for each image.

11. The method according to claim 9, wherein, upon extracting the portions of the image data, a predetermined longitudinal divided region of the processed image data are extracted for each image.

12. The method according to claim 9, wherein, upon extracting the portions of the image data, a predetermined lateral divided region of the processed image data are extracted for each image.

13. The method according to claim 9 further comprising selecting a region of the image data to be extracted, and

wherein, upon extracting the portions of the image data, image data of the selected region is extracted.

14. The method according to claim 9, wherein the plurality of associated images include a series of successively sensed images.

15. The method according to claim 9, wherein the plurality of associated images include a series of images sensed successively while changing an exposure.

16. The method according to claim 9, wherein in extraction, an extraction region from each processed image data is determined in accordance with the number of associated images.

18. A computer-readable recording medium wherein the medium records a program for causing a computer to execute the processing steps of the image display control method defined in claim 9.
