Abstract: A method includes: obtaining a first preview picture collected by a camera, where an angle of view FOV of the camera is a first FOV value, the camera collects the first preview picture based on a second FOV value, and the second FOV value is less than the first FOV value; adjusting the second FOV value to a third FOV value when it is detected that a quantity of at least one target human face in the first preview picture is greater than a first preset value, where the third FOV value is greater than the second FOV value, and the third FOV value is less than or equal to the first FOV value; and outputting an image that is photographed by the camera based on the third FOV value.

Abstract: A method for blockchain generation is provided. The method includes: sending, by a client, transaction information to a first node device, where the transaction information includes basic information and digest information; receiving, by the client, an endorsement result sent by the first node device, where the endorsement result includes a signature generated after the first node device successfully performs transaction simulation; and if the endorsement result meets a preset transaction condition, sending, by the client, the digest information and the endorsement result to a second node device, so that the second node device sends, to the first node device the digest information to generate a complete blockchain. In this way, only the digest information is transmitted between the first node device and the second node device. Therefore, the second node device does not obtain the complete transaction information, so that information security is improved.

Abstract: A method includes obtaining a first preview picture collected by a camera, where an angle of view FOV of the camera is a first FOV value. The camera collects the first preview picture based on a second FOV value, and the second FOV value is less than the first FOV value. The method further includes adjusting the second FOV value to a third FOV value when it is detected that a quantity of at least one target human face in the first preview picture is greater than a first preset value, where the third FOV value is greater than the second FOV value, and the third FOV value is less than or equal to the first FOV value; and outputting an image that is photographed by the camera based on the third FOV value.

Abstract: A consensus process recovery method and a related node, where the method includes determining, by a plurality of nodes, a target instance from one or more secondary instances, where a throughput of the target instance is higher than a throughput of a primary instance, and obtaining, by a first node and all second nodes, a consensus to replace the primary instance with the target instance as a new primary instance, where the second nodes are backup nodes running the target instance, and the first node is a primary node running the target instance.
