Abstract
A drawing image sharing apparatus captures an image being displayed onto a first drawing object as a captured image, before displaying a drawing image of a second drawing object onto the first drawing object. The drawing image sharing apparatus generates a differential image that reflects the difference between the captured image and a previous projection image, and transmits the differential image for projection onto the second drawing object.
Claims20
A drawing image sharing system, comprising:
- an image receive to receive a drawing image that reflects drawings drawn onto a second drawing object located at a remotely located site that is remote from a site at which a first drawing object is located;
- an image obtainer to cause an image capturing device to obtain an image being displayed onto the first drawing object as a captured image;
- an image supplier to cause a projection device to project the drawing image of the second drawing object onto the first drawing object as a projection image;
- a differential image generator to obtain a previous projection image that is previously projected onto the first drawing object from a memory, and to generate a differential image that reflects the difference between the previous projection image and the captured image obtained by the image obtainer;
- a storage to store the projection image being projected onto the first drawing object in the memory as a previous projected image to be used for next processing;
- and
- an image transmit to transmit the differential image to the remotely located site for projection onto the second drawing object as a drawing image of the first drawing object.
A drawing image sharing method, comprising:
- receiving a drawing image that reflects drawings drawn onto a second drawing object located at a remotely located site that is remote from a site at which a first drawing object is located;
- obtaining an image being displayed onto the first drawing object as a captured image;
- projecting the drawing image of the second drawing object onto the first drawing object as a projection image;
- obtaining a previous projection image that is previously projected onto the first drawing object from a memory;
- generating a differential image that reflects the difference between the previous projection image and the captured image;
- storing the projection image being projected onto the first drawing object in the memory as a previous projected image to be used for next processing;
- and
- transmitting the differential image to the remotely located site for projection onto the second drawing object as a drawing image of the first drawing object.
A recording medium storing a plurality of instructions which, when executed by a processor, cause the processor to perform a drawing image sharing method, the method comprising:
- receiving a drawing image that reflects drawings drawn onto a second drawing object located at a remotely located site that is remote from a site at which a first drawing object is located;
- obtaining an image being displayed onto the first drawing object as a captured image;
- projecting the drawing image of the second drawing object onto the first drawing object as a projection image;
- obtaining a previous projection image that is previously projected onto the first drawing object from a memory;
- generating a differential image that reflects the difference between the previous projection image and the captured image;
- storing the projection image being projected onto the first drawing object in the memory as a previous projected image to be used for next processing;
- and
- transmitting the differential image to the remotely located site for projection onto the second drawing object as a drawing image of the first drawing object.
