AI Technical Summary

⚠Technical Problem

When overlaying information onto a display screen, existing technologies suffer from the problem of overlap between the information to be overlaid and the display screen, resulting in blurred characters and reduced readability. Existing methods cannot effectively solve the problem of actively selecting the overlay position.

⚗Method used

By dividing the display screen into blocks, calculating the comprehensive weight value of each display sub-block, and performing a weighted sum based on spatial, temporal, and positional inertial weights, display sub-blocks whose comprehensive weight values ​​meet preset requirements are selected to form an overlay area, and the color of the information to be overlaid is adjusted.

🎯Benefits of technology

It enables the active selection of overlay positions on the display screen, reducing the impact of the overlay information on the display screen and improving the display effect and readability of the overlay information.

Abstract

The application relates to an information superimposition method suitable for a display picture, which comprises the following steps: performing weighted calculation on each display sub-block according to a preset display area position influence weight to obtain a comprehensive weight value of each display sub-block; combining display sub-blocks with comprehensive weight values meeting preset requirements to obtain a to-be-superimposed area; and displaying to-be-superimposed information at the to-be-superimposed area. The method selects a certain number of display sub-blocks with low display picture change degrees as the information superimposition area by calculating the comprehensive weight values of the display sub-blocks, so that the influence of the display picture on the to-be-superimposed information can be reduced as much as possible.
