Abstract: Methods, systems, and devices for adjusting a scanning status are provided. In one example method, a mobile terminal can determine whether a target object is a preset target type. If so, a reference scan parameter is determined corresponding to the preset target type, and a real-time scan parameter is obtained that is used when the mobile terminal performs scanning around the target object. A determination is made as to whether the real-time scan parameter conforms to the reference scan parameter. If it does not, a prompt message used to prompt a user to adjust a scanning status corresponding to a current scan parameter is generated.

Abstract: The present invention discloses an inter-frame predictive coding method and a coder. Inter-frame predictive coding is sequentially performed on frames in multiple groups of pictures by using a group of pictures as a unit; a correlation between the reference B frame and a GPB frame in the same group of pictures is used; and when the maximum depth of the CTU in the same position in the GPB frame is smaller, a quantity of mode decisions performed on the CTU in the reference B frame may be relatively small, so that an objective of reducing complexity of an inter-frame predictive coding process of the reference B frame is achieved.

Abstract translation: 本发明公开了一种帧间预测编码方法和编码方法。 通过使用一组图像作为一个单元，对多组图像中的帧顺序执行帧间预测编码; 使用同一组图像中的参考B帧和GPB帧之间的相关性; 并且当在GPB帧中相同位置的CTU的最大深度较小时，在参考B帧中对CTU执行的模式决定的数量可能相对较小，从而降低帧间复杂度的目标 实现了参考B帧的预测编码处理。
