Power management image data processing method in thermal printing
By constructing thermal history residual maps and frequency domain feature distribution maps, and using a dynamic frequency domain sparsification engine for adaptive sparsification processing, the problems of current overload and image quality degradation in thermal printing are solved, achieving a dual balance between current overload protection and image fineness during high-blackness printing.

Abstract
This invention relates to the fields of image data processing and thermal printing control technology, specifically a power consumption management image data processing method for thermal printing, including: a spatial construction and vector definition step: receiving data and establishing a coordinate system and image vectors; a thermal history residue construction step: combining a thermal model to construct a residue map representing thermal energy accumulation; a frequency domain feature extraction step: identifying frequency features and dividing solid and texture regions; a dynamic sparsification decision step: generating an adaptive mask based on thermal-frequency dual-domain constraints; and a logic synthesis and closed-loop update step: generating low-power data and updating the thermal cache. This invention utilizes thermal diffusion characteristics to guide sparsification in reverse, solving the problem of high-blackness printing current overload and maintaining visual integrity.
