  • Patent number: 11985471
    Abstract: A communication apparatus capable of easily switching communication between the communication apparatus and an external reproduction device. A communication section performs wireless communication with an earphone that is capable of automatically switching audio data transmitted from a plurality of communication apparatuses including the communication apparatus and reproducing the audio data. A state detection section detects whether or not the communication apparatus is used by a user. In a state in which the communication apparatus has not been used, when it is detected that the communication apparatus is used, the communication unit transmits a reproduction switching signal for switching the earphone to a state for reproducing audio data transmitted from the communication apparatus to the earphone before transmitting the audio data.

  • Publication number: 20230334766
    Abstract: The degree of similarity calculation unit calculates the degree of similarity between the virtual viewpoint parameters of the virtual viewpoint operated by its own apparatus and the virtual viewpoint parameters of another virtual viewpoint and in a case where it is determined that the degree of similarity satisfies a similarity condition determined in advance, the control unit causes the display of the image display unit to be changed. For example, the warning display for giving a notification that another virtual viewpoint whose virtual viewpoint parameters are similar exists and the image capturing frame of the other similar virtual viewpoint are displayed together with the virtual viewpoint image representing the appearance from the virtual viewpoint operated by the operator him/herself.

  • Patent number: 10748255
    Abstract: An image blur correction device acquires a blur detection signal, and separates it into a high frequency band signal component and a low frequency band signal component using an HPF and an LPF. A high frequency side prediction processing unit acquires an output of the HPF, and a low frequency side prediction processing unit acquires an output of the LPF via a down-sampler. A prediction processing unit updates a filter coefficient of a prediction filter using an adaptive algorithm, and performs linear prediction on the blur detection signal. An adder adds an output of the high frequency side prediction processing unit to an output of the low frequency side prediction processing unit via an up-sampler, and outputs a superimposed output signal. Image blur correction control is performed on the basis of a superimposed output signal.
