Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to Chinese Patent Application No. 202311635842.X, filed with the China National Intellectual Property Administration on December 1, 2023 and entitled "INFRARED REMOTE CONTROL METHOD AND TERMINAL DEVICE", which is incorporated herein by reference in its entirety. TECHNICAL FIELD This application pertains to the terminal field, and in particular, to an infrared remote control method, an electronic device, a computer storage medium, and a computer program product. BACKGROUND With continuous development of the internet of things, terminal devices such as smartphones become a most important mobile control manner in smart home control systems. For example, a user can implement remote control functions of a plurality of home appliances, such as a light, an air conditioner, and a television, through remote control applications on a mobile phone. To implement an infrared remote control function of a terminal device in a conventional technology, an additional circuit module needs to be added to the terminal device, increasing costs and design complexity of the terminal device. In addition, an existing terminal device has a small remote control emission angle. During use of remote control, an infrared emitting end of the terminal device needs to align with a controlled device; otherwise, signals transmitted by the terminal device cannot be transmitted to the controlled device. Consequently, the existing terminal device is still inconvenient in signal transmission control, affecting user experience. SUMMARY Embodiments of this application disclose an infrared remote control method, an electronic device, a computer storage medium, and a program product. According to this application, an infrared remote control function is implemented on an electronic device based on a TOF module, so that design complexity of the electronic device can be reduced. According to this application, 360-degree omnidirectional remote control can be performed on a controlled electronic device. The TOF module is widely used in various electronic devices, to detect a distance of a target object. In some scenarios, a terminal device may use the TOF module to perform 3D imaging and face unlock. The TOF module includes an emitting end (for example, an infrared light source), a receiving end, and a chip. A light source of the TOF module may be configured to emit infrared light, and may include an infrared light-emitting diode. The infrared light-emitting diode is configured to emit infrared light. The receiving end may receive infrared light that is emitted by the infrared light-emitting diode and that is reflected back after being projected onto an object. The chip may control emission of the infrared light, and calculate a time difference between emission and reception of the light, to obtain a distance of the to-be-shot object through calculation. Therefore, the infrared light-emitting diode in the TOF module can function as an infrared light emitter in this application, to implement the infrared remote control function of the electronic device. Based on this, according to a first aspect, this application provides an infrared remote control method, applied to an electronic device. The electronic device may include a TOF module and a processing chip. The TOF module includes a TOF sensor, a driver chip, and a light source configured to transmit an infrared optical signal, where the driver chip is electrically connected to two ends of the light source. The infrared remote control method includes: at a first moment, controlling the light source to transmit a first infrared optical signal to a user, controlling the TOF sensor to collect image data, and performing facial recognition based on the image data; and at a second moment, in response to a tap instruction or a voice instruction of the user, controlling the light source to transmit a second infrared optical signal to a controlled electronic device, or sending a control signal to the driver chip, to enable the driver chip to control the light source to transmit the second infrared optical signal to the controlled electronic device. The first moment is before the second moment. It may be understood that before the user performs infrared remote control on the controlled electronic device by using the electronic device, that is, at the first moment, the light source may be controlled to emit infrared light (namely, the first infrared optical signal) to the user to perform facial recognition. If the user succeeds in facial recognition, that is, unlocks an infrared remote control function of the electronic device, at the second moment, in response to the tap instruction or the voice instruction of the user, the light source may be controlled to emit infrared light (namely, the second infrared optical signal) to the controlled electronic device at a predetermined frequency. This can implement the infrared remote control function on
