Focus control method and device

The invention provides a focus control method and device. The method comprises the following steps: determining the row/line of target data via an acquired current direction key value; when the row/line of the target data is different from that of an anchor point, and the last row/line of a data source, corresponding to a data item, in the direction of the current direction key value is not displayed on a screen, fixing the position of a focus on the screen; moving each data item; and updating the row/line of the anchor point into that of the target data. The method can be used for fixing the position of the focus, and updating data items corresponding to the focus in a rolling manner, so that the focus control efficiency is improved. 本发明提供了种焦点控制方法和装置，该方法通过获取的当前方向键值确定目标数据行/列，当目标数据行/列与锚点行/列不同，且数据项对应的数据源在当前方向键值的方向上的最后行/列没有显示在屏幕上，则固定焦点在屏幕上的位置，移动各个数据项，将锚点行/列更新为目标数据行/列。该方法能够固定焦点位置，对焦点对应的数据项进行滚动更新，提高焦点控制效率。
