Image print system

An image-processing method comprising the steps of:

• processing an externally input image signal, thereby to generate image data to be supplied to a display apparatus;
• inserting the generated image data into a packet that complies with a predetermined digital serial bus system;
• inserting, into the packet, a capture command which includes a set of parameters that define a still-picture derived from said generated image data, said parameters describing image-type data representing a format of the still-picture data, said still-picture data defining said still-picture;
• and
• outputting the packet to a printing apparatus to print the still-picture defined by said parameters.

A printing apparatus comprising:

• image input means for receiving image data of a prescribed format, which is contained in a packet complying with a predetermined digital serial bus system;
• image-converting means for converting the format of the image data input to the image input means to a format for printing;
• and
• printing means for printing still-picture image data based on the image data of the format converted by the image-converting means;
• wherein the packet contains a capture command designating transmission of the still-picture data and describing image-type data representing the format of the still-picture data, said capture command includes a set of parameters that define a still-picture derived from said generated image data;
• and
• wherein the image-converting means converts the format in accordance with the image-type data described in the capture command.

A printing method comprising the steps of:

• receiving a packet complying with a predetermined digital serial bus system and containing image data and a capture command designating transmission of still-picture data based on the image data;
• converting the format of the image data received, to a format for printing, in accordance with image-type data described in the capture command and representing the format of the still-picture data received;
• and
• printing still-picture image data based on the image data of the format converted;
• wherein said capture command includes a set of parameters that define a still-picture derived from said generated image data.

An image-printing system comprising:

• an image-processing apparatus comprising image-processing means for processing an externally input image signal, thereby to generate image data to be supplied to a display apparatus;
• and
• image output means for deriving from said generated image data a packet, said packet complying with a predetermined digital serial bus system and containing the image data generated by the image-processing means;
• capture command means for inserting into the packet a capture command which includes a set of parameters that define a still-picture derived from said generated image data, said parameters describing, image-type data representing a format of the still-picture data, said still-picture data defining said still-picture;
• and
• means for transmitting said packet to a printing apparatus to print the still-picture defined by said parameters;
• and
• a printing apparatus comprising
• image input means for receiving image data of a prescribed format, which is contained in a packet complying with a predetermined digital serial bus system;
• image-converting means for converting the format of the image data input to the image input means to a format for printing;
• and
• printing means for printing still-picture image data based on the image data of the format converted by the image-converting means;
• wherein the image-converting means converts the format in accordance with the image-type data described in the capture command.
