Embodiment approach

[0140] Such as Figure 10 As shown, when the viewer's viewing position is not correct or the position of the projector and the projection screen is not correct, the depth or image sensor on the smart glasses device 610 ( Figure 10 Not shown in ) real-time capture of the user's current viewing environment, in the imaging analysis module ( Figure 10 not shown in ), the actual display part 621 of the screen 620 can be obtained by using the classical image segmentation algorithm with known screen parameters (such as screen shape, aspect ratio, etc.) (this step is a prior art, and will not be described in detail in this embodiment) , through the position of the viewer, the position of the smart glasses device 610 and the position of the screen 620, the projection 622 of the actual display part 621 on the smart glasses device 610 can be obtained, for example Figure 10 Point a and point b on the smart glasses device 610 are the intersection points of the line connecting point A a...

Abstract

The invention discloses an imaging adjustment device and method. The device includes: an imaging analysis module, which is used to judge whether the current image of the object has deformation relative to the original image of the object, and generate and deform when the current image has deformation. Corresponding imaging correction information; imaging lens group, used to image the object, including multiple sub-regions with adjustable imaging parameters; lens adjustment module, adjusting the imaging parameters of the corresponding sub-regions of the imaging lens group according to the imaging correction information . The method and device of the present invention image the object through the imaging lens with adjustable imaging parameters in each sub-area, and the imaging parameters of each sub-area can be adjusted independently to adjust and correct the perspective deformation of the object, avoiding the object acquired by the user images are perspective-distorted to improve user experience.

Description

technical field [0001] The invention relates to the field of imaging technology, in particular to an imaging adjustment device and method. Background technique [0002] The Galilean telescope can form an upright virtual image 1030a of the observed object 1030 through a convex lens 1010 and a concave lens 1020, and change the angle between the virtual image and the eye, forming a visual effect of zooming in or pushing away the observed object along the optical axis 1040. By adjusting the focal length of the two lenses and the distance between them, the magnification and focus can be changed, such as Figures 12a-12c shown. [0003] Lenses with fixed focal lengths have been widely used in optical devices such as glasses, telescopes, cameras, and microscopes. By combining lenses with different focal lengths and adjusting the distance between the lenses, the lens group can dynamically adjust the focal length. In addition, such as U.S. patent applications with publication number...
