description The invention provides a method and a system for automatically adjusting the display direction of a playing picture. The method includes: carrying out Object analysis on each frame of image of a videofilm; comparing the color gradation distribution curves of at least one object in two adjacent frames of images; judging objects with similar color scale distribution curves in two adjacent frames ofimages as the same object; comparing the azimuth information of the same object in the two adjacent frames of images, and if the azimuth information of the same object in the next frame of image changes relative to the previous frame of image, judging that the shooting direction of the video film changes when the next frame of image is shot; And when it is judged that the shooting direction of the video film changes at the time point corresponding to the next frame of image, adjusting the image display direction of the video film at the time point and the image display direction of each frameof image after the time po
