Embodiment Construction

[0022] The image adjustment method provided by the present invention can be applied to all projection terminals with projection functions, such as professional equipment such as projectors. It is better to apply it to mobile phones and other portable intelligent terminals with projection functions. As an example for description, the present invention will be further explained by means of specific embodiments in conjunction with the accompanying drawings.

[0023] figure 1 It is a schematic diagram of the projected image when the projection terminal shakes, which is represented by figure 1 It can be seen that when the user operates the projection terminal, it may cause the projection terminal to vibrate. For the convenience of description, in the normal use of the projection terminal, set figure 1 In the X-Y-Z space coordinate system, the jitter of the projection terminal will drive the jitter of the projection optical axis of the projection terminal. However, no matter how th...

Abstract

The invention provides an image correcting method for a projection terminal and the projection terminal. The image correcting method comprises the steps that the horizontal deflection angle of the projection terminal is acquired, and a to-be-projected image of the projection terminal is rotated and corrected according to the horizontal deflection angle and the projection optical axis of the projection terminal. According to the image correcting method for the projection terminal and the projection terminal, the horizontal deflection angle of the projection terminal is acquired, the to-be-projected image is rotated according to the horizontal deflection angle, and therefore the problem that the projection picture is distorted when the projection terminal is rotated with the projection optical axis as the center is solved; meanwhile, due to the fact that only to-be-projected image rotating is referred in the correcting process, a complex graph correction algorithm is not needed to carry out correction, cost is low, the correcting speed is high, the power consumption and the produced heat are low, and the using experience of a user of a portable terminal is greatly improved.

Description

technical field [0001] The invention relates to the field of correction of projection images, in particular to an image correction method for a projection terminal and the projection terminal. Background technique [0002] At present, portable terminals with projection functions are becoming more and more popular. While improving the user experience, it also brings some problems. For example, when playing slideshows, users often hold and operate portable terminals with their hands, which may cause Shaking or shifting of the projection angle will cause the angle deflection of the display screen or the stretching and deformation of the display content, which will affect the viewing of the display content and reduce the applicability of the projection function. Aiming at the display image distortion problem caused by the jitter of the projector, the existing technology also provides corresponding solutions, such as obtaining the horizontal deflection, vertical deflection and th...
