Image transmission/reception system, image transmission apparatus, image reception apparatus, image transmission/reception method, and program

An image transmission apparatus comprising:

• an image generation unit configured to generate a first image and generate a second image after generating the first image;
• an image data transmission unit configured to transmit first image data generated on a basis of the first image to an image reception apparatus,
• the image reception apparatus including
• an image data reception unit configured to receive the first image data,
• a to-be-displayed image generation unit configured to generate a first to-be-displayed image on a basis of the first image data,
• an alternative image generation unit configured to generate an alternative image by estimating, on the basis of the first image data, a second to-be-displayed image to be generated on a basis of second image data generated on a basis of the second image by the to-be-displayed image generation unit, and
• a display control unit configured to display, after displaying the first to-be-displayed image, any one of the second to-be-displayed image generated on the basis of the second image data and the alternative image, depending on whether or not reception of the second image data has succeeded;
• and
• a transmission control unit configured to control whether or not to transmit the second image data generated on the basis of the second image to the image reception apparatus on a basis of a possibility of successful estimation of the second to-be-displayed image on the basis of the first image data by the alternative image generation unit, the possibility being determined on a basis of a feature amount of the first image and a feature amount of the second image.

An image reception apparatus comprising:

• an image data reception unit configured to receive first image data from an image transmission apparatus;
• a to-be-displayed image generation unit configured to generate a first to-be-displayed image on a basis of the first image data;
• an alternative image generation unit configured to generate an alternative image by estimating, on the basis of the first image data, a second to-be-displayed image to be generated on a basis of second image data by the to-be-displayed image generation unit;
• and
• a display control unit configured to display, after displaying the first to-be-displayed image, any one of the second to-be-displayed image generated on the basis of the second image data and the alternative image, depending on whether or not reception of the second image data has succeeded, whether or not to transmit the second image data being controlled by the image transmission apparatus on a basis of a possibility of successful estimation of the second to-be-displayed image on the basis of the first image data by the alternative image generation unit, the possibility being determined on a basis of a feature amount of the first image and a feature amount of the second image.

An image transmission/reception method comprising:

• generating a first image;
• generating a second image after generating the first image;
• transmitting first image data generated on a basis of the first image;
• controlling whether or not to transmit second image data generated on a basis of the second image;
• receiving the first image data;
• generating a first to-be-displayed image on a basis of the first image data;
• generating an alternative image by estimating, on the basis of the first image data, a second to-be-displayed image to be generated on a basis of the second image data in the to-be-displayed image generation;
• and
• displaying, after displaying the first to-be-displayed image, any one of the second to-be-displayed image generated on a basis of the second image data and the alternative image, depending on whether or not reception of the second image data has succeeded,
• wherein, the controlling controls whether or not to transmit the second image data on a basis of a possibility of successful estimation of the second to-be-displayed image on the basis of the first image data in the alternative image generation, the possibility being determined on a basis of a feature amount of the first image and a feature amount of the second image.

A non-transitory, computer readable storage medium containing a computer program, which when executed by a computer, causes the computer to perform an image transmission/reception method by carrying out actions, comprising:

• generating a first image;
• generating a second image after generating the first image;
• transmitting first image data generated on a basis of the first image to an image reception apparatus,
• wherein the generating the first image and the second image includes receiving the first image data, generating a first to-be-displayed image on a basis of the first image data, generating an alternative image by estimating, on the basis of the first image data, a second to-be-displayed image to be generated on a basis of second image data generated on a basis of the second image by the to-be-displayed image generation unit, and displaying, after displaying the first to-be-displayed image, any one of the second to-be-displayed image generated on the basis of the second image data and the alternative image, depending on whether or not reception of the second image data has succeeded;
• and
• controlling whether or not to transmit the second image data generated on the basis of the second image to the image reception apparatus on a basis of a possibility of successful estimation of the second to-be-displayed image on the basis of the first image data, the possibility being determined on a basis of a feature amount of the first image and a feature amount of the second image.
