Data transmission method, camera and electronic device

A data transmission method, comprising:

• receiving a first image frame whose effective image area carries target data, through a same transmission channel as used in transmitting image data;
• wherein the target data is different from the image data and coaxial data, the coaxial data is notification information for an interaction between a data receiving end and a data sending end, and the first image frame has a different type from a second image frame carrying the image data without carrying the target data;
• wherein the target data comprises:
• target data indicating environmental information of an environment in which an image capture device is located, of the image data;
• and/or, target data indicating audio information captured by the image capture device, of the image data;
• and/or, target data indicating image information of the image data;
• and
• acquiring the target data from the effective image area by using a data acquisition manner for the effective image area;
• wherein the first image frame and the second image frame are alternately sent;
• wherein receiving a first image frame whose effective image area carries target data comprises:
• receiving a preset number of second image frames, then when it is determined that the preset number of second image frames have been continuously received, receiving an image frame and determining the received image frame as the first image frame whose effective image area carries the target data;
• then after receiving the first image frame, continuously receiving the preset number of second image frames.

A camera, comprising:

• a processor, a communication interface, a memory and a communication bus;
• wherein, the processor, the communication interface and the memory communicate with each other via the communication bus;
• the processor is configured for:
• acquiring to-be-sent target data;
• and sending the target data, as data carried in an effective image area of a first image frame, by using a data sending manner for the effective image area, through a same transmission channel as used in transmitting image data;
• wherein the target data is different from the image data and coaxial data, the coaxial data is notification information for an interaction between a data receiving end and a data sending end, wherein the target data comprises:
• target data indicating environmental information of an environment in which an image capture device is located, of the image data;
• and/or, target data indicating audio information captured by the image capture device, of the image data;
• and/or, target data indicating image information of the image data;
• and the first image frame has a different type from a second image frame carrying the image data without carrying the target data;
• wherein the first image frame and the second image frame are alternately sent;
• the memory is configured for storing the target data acquired by the processor;
• wherein, the processor is further configured for:
• before sending the target data, sending a preset number of second image frames, then when determining that the preset number of second image frames have been continuously sent, sending the target data, as data carried in the effective image area of the first image frame, by using the data sending manner for the effective image area, through the same transmission channel as used in transmitting the image data;
• wherein, the processor is further configured for:
• when the sending of the target data is completed, continuously sending the preset number of second image frames.

An electronic device, comprising:

• a processor, a communication interface, a memory and a communication bus;
• wherein, the processor, the communication interface and the memory communicate with each other via the communication bus;
• the processor is configured for:
• receiving a first image frame whose effective image area carries target data, through a same transmission channel as used in transmitting image data;
• and acquiring the target data from the effective image area by using a data acquisition manner for the effective image area;
• wherein the target data is different from the image data and coaxial data, the coaxial data is notification information for an interaction between a data receiving end and a data sending end, and the first image frame has a different type from a second image frame carrying the image data without carrying the target data;
• wherein the target data comprises:
• target data indicating environmental information of an environment in which an image capture device is located, of the image data;
• and/or, target data indicating audio information captured by the image capture device, of the image data;
• and/or, target data indicating image information of the image data;
• and
• the memory is configured for storing the target data acquired by the processor;
• wherein the first image frame and the second image frame are alternately sent;
• wherein, the processor, when receiving the first image frame whose effective image area carries target data, is configured for:
• receiving a preset number of second image frames, then when determining that the preset number of second image frames have been continuously received, receiving an image frame and determining the received image frame as the first image frame whose effective image area carries the target data;
• wherein, the processor is further configured for:
• after receiving the first image frame, continuously receiving the preset number of second image frames.
