Embodiment Construction

[0047] The conventional focusing method of a projector is to project a pre-selected pattern on a projection screen by the projector at different focal length positions, and the focal position corresponding to the projection image with the best definition is the focusing position of the projector.

[0048] This method of focusing the projector requires that the image projected by the projector must be obtained by projecting a pattern pre-stored in the projector. Then if the user finds that the projected image is not good during the process of using the projector, he needs to adjust the focus of the projector. At this time, the projector will cover the image that the user is watching and play, and the pre-stored image in the projector With projection, the user is forced to stop watching the current projection screen or video, which brings a bad user experience to the user.

[0049] In addition, when the projector is used to adjust the focus of the image, the projector’s pre-stored im...

Abstract

The invention discloses an image definition determination method, which comprises the steps of performing gray processing on a to-be-evaluated image to obtain a gray image of the to-be-evaluated image; sequentially obtaining a first gray value variance of each pixel point in the gray image; wherein the process of obtaining the first gray value variance of each pixel point comprises the following steps: performing normalization processing on the pixel point and the gray value of each adjacent pixel point in a preset adjacent region corresponding to the pixel point, and then performing operationof the first gray value variance, thereby obtaining the definition of the to-be-evaluated image. According to the method, the influence of different image textures on the definition of the image canbe eliminated to a certain extent, the image of the image or video being watched by the user can be directly collected as the to-be-evaluated image, the problem that the user is interrupted when usingthe projector is avoided, and the user experience is improved. The invention further provides an image definition evaluation device, automatic focusing projector equipment and a computer readable storage medium, which have the above beneficial effects.

Description

Technical field [0001] The present invention relates to the technical field of image analysis, in particular to a method and device for determining image clarity, an autofocus projector device and a computer-readable storage medium. Background technique [0002] A projector is a device used to project videos and images to a projection plane, and its clarity directly affects the user's viewing experience. When the image projected by the projector is not clear, the projector can focus by adjusting the projector lens to ensure that the projected image of the projector is clearer. [0003] However, in various current projection devices, if the user finds that the projection screen is not clear, he must pause the video or image he is watching and perform projection focusing, which greatly affects the user experience. Summary of the invention [0004] The purpose of the present invention is to provide a method, device, device, and computer-readable storage medium for determining the defi...
