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 input unit to input image data;

an image dividing unit to divide the image data to generate divided image data items;

an image data storage unit 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;

a notification data generation unit to generate notification data items each including a corresponding divided image data item and a corresponding position data item acquired from the image data storage unit; and

a transmission unit to sequentially transmit the notification data items to the second image processing apparatus, and

wherein the second image processing apparatus includes;

a reception unit to receive the notification data items from the first image processing apparatus; and

an image data reproduction unit to reproduce the image data by developing the divided image data items in order of receipt of the divided image data items based on the divided image data items and the position data items included in the notification data items.

2. The information sharing system of claim 1, wherein the first image processing apparatus further includes:

a selection unit to select one of a plurality of communication bandwidths,

wherein the image dividing unit acquires a division size corresponding to the selected communication bandwidth and divides the image data based on the division size.

3. The information sharing system of claim 2, wherein the image dividing unit of the first image processing apparatus divides the image data based on a predetermined division size if no communication bandwidth is selected by the selection unit.

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

5. An image processing apparatus, comprising:

an image input unit to input image data;

an image dividing unit to divide the image data to generate divided image data items;

an image data storage unit 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;

a notification data generation unit to generate notification data items each including a corresponding divided image data item and a corresponding position data item acquired from the image data storage unit; and

a transmission unit to sequentially transmit the notification data items to a counterpart image processing apparatus via a communication network to cause the counterpart image processing apparatus to reproduce the image data by developing the divided image data items in order of receipt of the divided image data items based on the divided image data items and the position data items included in the notification data items.

6. The image processing apparatus of claim 5, further comprising:

a selection unit to select one of a plurality of communication bandwidths,

wherein the image dividing unit acquires a division size corresponding to the selected communication bandwidth and divides the image data based on the division size.

7. The image processing apparatus of claim 6, wherein the image dividing unit divides the image data based on a predetermined division size if no communication bandwidth is selected by the selection unit.

8. The image processing apparatus of claim 5, wherein the image input unit inputs image data of an image frame conforming to Joint Photographic Experts Group 2000 standard.

9. 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 divided image data item and a corresponding position data item acquired from the memory; and

sequentially transmitting the notification data items to a counterpart image processing apparatus to cause the counterpart image processing apparatus to reproduce the image data by developing the divided image data items in order of receipt of the divided image data items based on the divided image data items and the position data items included in the notification data items.
