Abstract

In a display apparatus connected to an image processing apparatus which detects the change amount in an input image and stores, as a detected image, an image during a period with a change amount equal to or more than a predetermined amount, the change log of the change amount and the detected image are received, the change log is displayed by using a graph, and information related to the detected image is displayed on the graph in a superposed manner.

Claims

1. An apparatus comprising:

a receiving unit configured to receive images captured by a capturing unit; and

an acquiring unit configured to acquire a degree of change in a first image of the images captured by the capturing unit based on a difference between the first image captured by the capturing unit and a second image which is generated based on a plurality of images captured by the capturing unit before the first image is captured by the capturing unit; and

a display control unit configured to cause a display unit to display the first image received by the receiving unit and to display a graph which indicates the degree of change in the first image.

2. The apparatus according to claim 1, further comprising a determination unit configured to determine a parameter for detecting a moving object.

3. The apparatus according to claim 1, wherein the display control unit is configured to cause the display unit to display the graph which indicates a chronological degree of change in the images captured by the capturing unit.

4. The apparatus according to claim 1, wherein the graph indicates a degree of a motion of an object in the first image.

5. The apparatus according to claim 1, wherein the display control unit is configured to cause the display unit to display, together with the graph which indicates the degree of change in the first image, a graphical user interface for setting a parameter used to detect a moving object in the first image.

6. The apparatus according to claim 1, wherein the degree of change is determined based on at least one of RGB components or YCbCr components of pixels, a lightness of pixels, code amounts of JPEG coded blocks, or DCT coefficients in a JPEG coded block of the first image.

7. The apparatus according to claim 1, wherein the display control unit is configured to cause the display unit to display the graph based on a histogram about the images captured by the capturing unit.

8. The apparatus according to claim 1, wherein the display control unit is configured to cause the display unit to display the graph together with the images captured by the capturing unit.

9. The apparatus according to claim 1, wherein the receiving unit is configured to receive the images from the capturing unit via a network.

10. A system comprising:

a receiving unit configured to receive images captured by a capturing unit;

an acquiring unit configured to acquire a degree of change in a first image of the images captured by the capturing unit based on a difference between the first image captured by the capturing unit and a second image which is generated based on a plurality of images captured by the capturing unit before the first image is captured by the capturing unit; and

a display control unit configured to cause a display unit to display the first image received by the receiving unit and to display a graph which indicates the degree of change in the first image.

11. The system according to claim 10, wherein the display control unit is configured to cause the display unit to display the graph which indicates a chronological degree of change in the images by the capturing unit.

12. A method comprising:

receiving images captured by a capturing unit; and

acquiring a degree of change in a first image of the images captured by the capturing unit based on a difference between the first image captured by the capturing unit and a second image which is generated based on a plurality of images captured by the capturing unit before the first image is captured by the capturing unit; and

causing a display unit to display the first image received in the receiving step and to display a graph which indicates the degree of change in the first image.

16. The method according to claim 12, wherein the controlling step causes the display unit to display the graph which indicates a chronological degree of change in the images captured by the capturing unit.
