Problems solved by technology

[0003] However, when users use the above-mentioned equipment to shoot many dot-matrix display screens in life, it is difficult for the camera to capture the complete display content due to its display mechanism.
The dot matrix image is displayed line by line at a certain frequency, and only one line is displayed at the same time. For the human eye, the complete image can be seen, but the shooting time of the camera is very short, and often there is only one line or one line in the captured image. A few lines are displayed, and the user experience is extremely poor

Abstract

The present application provides an image acquisition method and device for a display screen, an electronic device, and a computer-readable medium. Wherein, the display screen is composed of a boundary and dot matrix display points within the boundary, and the method includes: positioning the boundary of the dot matrix display screen, collecting images of display points within the boundary according to a set time interval, and obtaining a multi-frame display For the dot image, based on the time sequence of collection, multiple frames of the display dot images are spliced, so as to obtain a display screen image composed of luminous display dots. Based on this solution, a complete and clear dot matrix screen pattern can be captured. Therefore, compared with the prior art, the user's shooting experience can be improved to a certain extent.

Description

technical field [0001] The present application relates to the technical field of image acquisition, in particular to an image acquisition method and device for a display screen, an electronic device, and a computer-readable medium. Background technique [0002] Recently, users often use electronic devices having a camera function. For example, recently used portable phones basically include cameras, and various types of equipment such as personal digital assistants (PDAs), tablet personal computers (PCs), and the like also include cameras. Image capturing devices (eg, digital cameras) that generate images by capturing images of subjects (eg, people, dot-matrix display screens in the background) and record the generated captured images have also become common. [0003] However, when a user uses the above-mentioned device to shoot many dot-matrix display screens in life, it is difficult for the camera to capture the complete display content due to its display mechanism. The ...
