AI Technical Summary

Technical Problem

Existing technologies, when reducing the transmit power of radio frequency devices, suffer from problems such as decreased uplink transmission and increased product design complexity and cost. In particular, they cannot effectively adjust the transmit power to meet specific absorption rate limits when a human body is near.

Method used

By using image recognition technology and acquiring scene and human detection information through cameras, the transmission power level of electronic devices is dynamically adjusted. Based on the relative position of the user and the antenna and the user's gaze, different modes are switched to optimize the transmission power.

Benefits of technology

This technology enables dynamic adjustment of transmit power to meet specific absorption rate limits while ensuring a good user experience, thereby increasing upload throughput and reducing costs.

Abstract

An electronic device comprises an antenna, a radio frequency transmission module, a camera, one or more memories and one or more processing circuits. The radio frequency transmission module transmits a radio frequency signal at a transmit power level through an antenna. The processing circuit accesses data and at least one instruction stored in the memory to execute the following steps. Performing scene detection on at least one image to obtain scene information; and judging whether to switch the operation mode to the handheld mode according to the scene information, and executing the following steps in the handheld mode. Performing human body detection on the at least one image to obtain human body detection information; estimating at least one handheld position according to the human body detection information; determining whether the at least one handheld position is adjacent to the antenna; if the handheld position is adjacent to the antenna, the transmit power level is reduced to a second level lower than the first level. The electronic device estimates the proximity between a user and the electronic device through image recognition so as to provide a dynamic specific absorption rate function. The invention also relates to a non-transitory computer readable recording medium.
