  • Patent number: 10236971
    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.

  • Patent number: 9805691
    Abstract: A display obtains a first image by image capturing, receives, from an external apparatus, a second image generated based on the first image, determines a communication quality with the external apparatus in reception of the second image, and controls to display the second image on a display unit until a value indicating a degree of degradation of the communication quality exceeds a first threshold as a result of determination, and display the first image on the display unit when the value indicating the degree of degradation of the communication quality exceeds the first threshold. The display controls to display the first image until the value indicating the degree of degradation of the communication quality becomes smaller than a second threshold smaller than the first threshold after exceeding the first threshold.

  • Patent number: 9679415
    Abstract: In order to easily and rapidly determine a subject region in a captured image using a single image, a synthesized image of an extraction image including a subject and an instruction image representing a first acquisition region from which color information on the subject is acquired is used. Color information on the subject is acquired from the first acquisition region represented by the instruction image in the synthesized image. Color information on a background of the subject is acquired from a region not including the first acquisition region and a color information non-acquisition region that is adjacent to the first acquisition region and is set in advance in the synthesized image. On the basis of the color information on the subject and the color information on the background, extraction information of the subject is determined and output.
