Abstract

An object of this invention is to simplify an operation of reproducing, on a single window, pieces of image information of different image capturing apparatuses or pieces of image information captured at different times. A display apparatus manages a camera apparatus (1) serving as the image capturing source of image information to be reproduced in each image region in association with a plurality of image regions on a single window. The display apparatus manages whether the image information to be reproduced in each image region is recorded image information or image information which is currently being captured. On the basis of the pieces of management information, the display apparatus acquires image information from a desired one of camera apparatuses and recording apparatuses and reproduces the pieces of acquired image information on the plurality of image regions.

an acquiring unit configured to acquire a first image which had been captured at a first time from an image recording apparatus, a second image which had been captured at a second time from the image recording apparatus, and a third image from the image capturing apparatus, in a case where the information read out by the reading unit indicates that a first capturing time of the first image is the first time, a second capturing time of the second image is the second time, and a third capturing time of the third image is the current time; and

a control unit configured to control the reproduction of the image such that the first image captured at the first time and acquired from the image recording apparatus, the second image captured at the second time and acquired from the image recording apparatus, and the third image captured by the image capturing apparatus are reproduced concurrently.

2. The apparatus according to claim 1, wherein

the acquiring unit acquires the latest image in a plurality of images captured at a past time corresponding to the image capturing time information in a case where the image capturing time information includes time information and does not include date information and the plurality of images are recorded by the image recording apparatus.

3. The apparatus according to claim, 1 wherein

the acquiring unit acquires the image captured at past time based on difference time information and the current time in a case where the image capturing time information includes the difference time information representing difference from the current time.

4. The apparatus according to claim 1, further comprising:

a detecting unit configured to detect the change in a state around the image capturing apparatus; and

a creating unit configured to create, in a case where the change in the state around the image capturing apparatus is detected by said detecting unit, the information to reproduce the image captured by the image capturing unit, one of a detection time and a predetermined time ago from the detection time.

5. An image reproduction controlling method of an image reproduction controlling apparatus for controlling a reproduction of an image, comprising steps of:

reading, from a storage device, information indicating identification information of an image capturing apparatus, and image capturing time information;

acquiring a first image which had been captured at a first time from an image recording apparatus, a second image which had been captured at a second time from the image recording apparatus, and a third image from the image capturing apparatus, in a case where the information read out by the reading step indicates that a first capturing time of the first image is the first time, a second capturing time of the second image is the second time, and a third capturing time of the third image is the current time; and

controlling the reproduction of the image such that the first image captured at the first time and acquired from the image recording apparatus, the second image captured at the second time and acquired from the image recording apparatus, and the third image captured by the image capturing apparatus are reproduced concurrently.

6. The method according to claim 5, wherein

the acquiring step acquires the latest image in a plurality of images captured at past time corresponding to the image capturing time information in a case where the image capturing time information includes time information and does not include date information and the plurality of images are recorded by the image recording apparatus.

7. The method according to claim 5, wherein

the acquiring step acquires the image captured at past time based on difference time information and the current time in a case where the image capturing time information includes the difference time information representing difference from the current time.

8. A computer-readable medium storing a program which causes a computer to execute an image reproduction controlling method of an image reproduction controlling apparatus for controlling a reproduction of an image, said image reproduction controlling method comprising steps of:

reading, from a storage device, information indicating identification information of an image capturing apparatus, and image capturing time information;

acquiring a first image which had been captured at a first time from an image recording apparatus, a second image which had been captured at a second time from the image recording apparatus, and a third image from the image capturing apparatus, in a case where the information read out by the reading step indicates that a first capturing time of the first image is the first time, a second capturing time of the second image is the second time, and a third capturing time of the third image is the current time; and

controlling the reproduction of the image such that the first image captured at the first time and acquired from the image recording apparatus, the second image captured at the second time and acquired from the image recording apparatus, and the third image captured by the image capturing apparatus are reproduced concurrently.

9. The medium according to claim 8, wherein

the acquiring step acquires the latest image in a plurality of images captured at past time corresponding to the image capturing time information in a case where the image capturing time information includes time information and does not include date information and the plurality of images are recorded by the image recording apparatus.

10. The medium according to claim 8, wherein

the acquiring step acquires the image captured at past time based on difference time information and the current time in a case where the image capturing time information includes the difference time information representing difference from the current time.

11. An image reproduction controlling apparatus for controlling a reproduction of an image, comprising:

a reading unit configured to read out, from a storage device, information indicating identification information of an image capturing apparatus, and image capturing time information;

an acquiring unit configured to acquire the latest image, from an image recording apparatus, in a plurality of images captured at past time corresponding to first image capturing time information, and to acquire a second image from the image capturing apparatus, in a case where the first image capturing time information of the first image includes time information and does not include date information, and second image capturing time information of the second image indicates the current time; and

a control unit configured to control the reproduction of the image such that the first image captured at the past time and acquired from the image recording apparatus and the second image captured by the image capturing apparatus are reproduced concurrently.

12. The apparatus according to claim, 11 wherein

the acquiring unit acquires a third image captured at past time based on difference time information and the current time in a case where the third image capturing time information includes the difference time information representing difference from the current time.

13. An image reproduction controlling method of an image reproduction controlling apparatus for controlling a reproduction of an image, comprising:
