Image transmission control device, method, and computer-readable recording medium storing program

An image transmission control method comprising:

• storing, in the memory, relationship information that indicates a correspondence relationship between a received signal strength indicator at a time of reception of a signal from a wireless transmission path and an available bandwidth of data transmission in the wireless transmission path;
• acquiring a measurement value of the received signal strength indicator during communication with an image transmission device that transmits image data via a communication path that includes the wireless transmission path;
• estimating a first available bandwidth in the wireless transmission path based on the measurement value and the relationship information;
• generating control information for adjustment of a transmission rate of image data in the image transmission device based on the first available bandwidth;
• transmitting the control information to the image transmission device;
• measuring, when image data that reflects the control information is received from the image transmission device, a second available bandwidth in the wireless transmission path based on the received image data;
• and
• optimizing the correspondence relationship in the relationship information based on a comparison result between the first available bandwidth and the second available bandwidth.

A non-transitory computer readable recording medium storing an image transmission control program causing a computer to execute a process of:

• storing, in the memory, relationship information that indicates a correspondence relationship between a received signal strength indicator at a time of reception of a signal from a wireless transmission path and an available bandwidth of data transmission in the wireless transmission path;
• acquiring a measurement value of the received signal strength indicator during communication with an image transmission device that transmits image data via a communication path that includes the wireless transmission path;
• estimating a first available bandwidth in the wireless transmission path based on the measurement value and the relationship information;
• generating control information for adjustment of a transmission rate of image data in the image transmission device based on the first available bandwidth;
• transmitting the control information to the image transmission device;
• measuring, when image data that reflects the control information is received from the image transmission device, a second available bandwidth in the wireless transmission path based on the received image data;
• and
• optimizing the correspondence relationship in the relationship information based on a comparison result between the first available bandwidth and the second available bandwidth.
