Abstract
To provide a technique capable of reducing the transmission delay of an image, a communication apparatus wirelessly communicable with another communication apparatus, receives a compressed captured image from the other communication apparatus; decompresses the compressed captured image to obtain a decompressed captured image; generates, based on the decompressed captured image, a CG image to be superimposed and displayed on the captured image; and compresses the CG image to generate a compressed CG image; transmits the compressed CG image to the other communication apparatus. Then, the communication apparatus derives a delay time based on a transmission time of the compressed captured image in the other communication apparatus and a generation completion time of the CG image; and changes a compression ratio of the CG image based on whether the delay time is longer than a predetermined threshold.
