Abstract

An information sharing system includes a first image processing apparatus and a second image processing apparatus connected thereto via a communication network. The first apparatus includes an input unit to input image data, a dividing unit to divide the data into divided image data items, a storage unit to store the divided image data items at respective destinations and output position data items indicating the destinations, a generation unit to generate notification data items each including a corresponding divided image data item and a corresponding position data item, and a transmission unit to sequentially transmit the notification data items to the second apparatus. The second apparatus includes a reception unit to receive the notification data items from the first apparatus and a reproduction unit to reproduce the image data by developing the divided image data items in order of receipt based on the data in the notification data items.

Claims

1. An information sharing system, comprising:

a first image processing apparatus; and

a second image processing apparatus connected to the first image processing apparatus via a communication network,

wherein the first image processing apparatus includes;

an image capture device to input image data;

processing circuitry configured to divide the image data to generate divided image data items;

an image data memory to store the divided image data items at respective storage destinations and output position data items indicating the respective storage destinations of the divided image data items, wherein the processing circuitry is further configured to generate notification data items each including a corresponding position data item acquired from the image data memory, the corresponding position data item including a URL indicating a storage location of the corresponding divided image data item in the image data memory; and

a transmitter to sequentially transmit the notification data items to the second image processing apparatus without transmitting the corresponding divided image data items at a same time, wherein the corresponding divided image data items are new image data not previously transmitted to the second image processing apparatus, and

wherein the second image processing apparatus includes;

a receiver to receive the notification data items from the first image processing apparatus before receiving the corresponding divided image data items; and

a processor to reproduce the image data by acquiring and processing each divided image data item using each corresponding URL included in the notification data items at a desired timing in accordance with a status of the second image processing apparatus after receiving the notification data items.

2. The information sharing system of claim 1, wherein the processing circuitry is further configured to select one communication bandwidth of a plurality of communication bandwidths, acquire a division size corresponding to the one selected communication bandwidth, and divide the image data based on the acquired division size.

3. The information sharing system of claim 2, wherein the processing circuitry divides the image data based on a predetermined division size when no communication bandwidth is selected.

4. The information sharing system of claim 1, wherein the image capture device of the first image processing apparatus inputs the image data, which is an image frame conforming to a Joint Photographic Experts Group 2000 standard.

5. The information sharing system of claim 1, wherein the transmitter transmits one notification data item for each divided image data item.

6. The information sharing system of claim 1, wherein the processor of the second image processing apparatus is configured to sequentially process and display an image based on each divided image data item as each divided image data item is acquired, and before all image data items are acquired.

7. An image processing apparatus, comprising:

an image capture device to input image data;

processing circuitry configured to divide the image data to generate divided image data items;

an image data memory to store the divided image data items at respective storage destinations and output position data items indicating the respective storage destinations of the divided image data items, wherein the processing circuitry is further configured to generate notification data items each including a corresponding position data item acquired from the image data memory, the corresponding position data item including a URL indicating a storage location of the corresponding divided image data item in the image data memory; and

a transmitter to sequentially transmit the notification data items to a counterpart image processing apparatus via a communication network, without transmitting the corresponding divided image data items at a same time, wherein the corresponding divided image data items are new image data not previously transmitted to the counterpart image processing apparatus, to cause the counterpart image processing apparatus to receive the notification data items before receiving the corresponding divided image data items and to reproduce the image data by acquiring and processing each divided image data item using each corresponding URL included in the notification data items at a desired timing in accordance with a status of the second image processing apparatus after receiving the notification data items.

8. The image processing apparatus of claim 7, wherein the processing circuitry is further configured to select one communication bandwidth of a plurality of communication bandwidths, acquire a division size corresponding to the one selected communication bandwidth, and divide the image data based on the acquired division size.

9. The image processing apparatus of claim 8, wherein the processing circuitry divides the image data based on a predetermined division size when no communication bandwidth is selected.

10. The image processing apparatus of claim 7, wherein the image capture device inputs the image data, which is an image frame conforming to a Joint Photographic Experts Group 2000 standard.

11. An image processing method, comprising:

inputting image data;

dividing the image data to generate divided image data items;

storing the divided image data items at respective storage destinations in a memory;

outputting position data items indicating respective storage destinations of the divided image data items;

generating notification data items each including a corresponding position data item acquired from the memory, the corresponding position data item including a URL indicating a storage location of the corresponding divided image data item in the memory; and

sequentially transmitting the notification data items to a counterpart image processing apparatus via a communication network, without transmitting the corresponding divided image data items at a same time, wherein the corresponding divided image data items are new image data not previously transmitted to the counterpart image processing apparatus, to cause the counterpart image processing apparatus to receive the notification data items before receiving the corresponding divided image data items and to reproduce the image data by acquiring and processing each divided image data item using each corresponding URL included in the notification data items at a desired timing in accordance with a status of the second image processing apparatus after receiving the notification data items.

12. The method of claim 11, wherein the dividing step comprises selecting one communication bandwidth of a plurality of communication bandwidths, acquiring a division size corresponding to the selected one communication bandwidth, and dividing the image data based on the acquired division size.

13. The method of claim 11, wherein the inputting step comprises inputting the image data, which is an image frame conforming to a Joint Photographic Experts Group 2000 standard.
