In one example method, after an electronic device receives a first target vertical synchronization signal, if an input event received by the electronic device is a target input event and meets a preset condition, the target input event is processed before a second target vertical synchronization signal arrives. The second target vertical synchronization signal is a next target vertical synchronization signal of the first target vertical synchronization signal. ## Claims ### Claim 1 An event processing method applied to an electronic device, wherein the event processing method comprises: receiving a first target vertical synchronization signal; receiving an input event; processing, in response to the input event being a target input event and meeting a preset condition, the target input event, wherein the preset condition comprises: a first time period corresponding to the target input event is less than a minimum reporting period of an input event, wherein the first time period indicates a time period between a moment at which the target input event is received and a moment at which a second target vertical synchronization signal arrives; and receiving the second target vertical synchronization signal, wherein the second target vertical synchronization signal is a next target vertical synchronization signal of the first target vertical synchronization signal. ### Claim 2 (depends on 1) The event processing method according to claim 1, wherein the processing the target input event comprises: drawing, based on the first target vertical synchronization signal, one or more layers corresponding to the target input event. ### Claim 3 (depends on 1) The event processing method according to claim 1, further comprising: processing another target input event received in a second time period, wherein the second time period indicates a time period between a moment at which the first target vertical synchronization signal is received and a moment at which the target input event is received. ### Claim 4 (depends on 1) The event processing method according to claim 1, further comprising: when the input event is the target input event and does not meet the preset condition, receiving a next input event. ### Claim 5 (depends on 1) The event processing method according to claim 1, wherein the target input event comprises a slide action event. ### Claim 6 An electronic device, comprising: at least one processor;
