Methods and systems for improving display resolution in achromatic images using sub-pixel sampling and visual error filtering

   
   

Embodiments of the present invention provide systems and methods for converting an achromatic, higher-resolution image to a lower-resolution image with reduced visible errors. These systems and methods comprise a sub-pixel sampling performed on a higher-resolution image. The sub-pixel sampled image is then converted to an opponent color domain image that is separated into separate luminance and chrominance channels. These chrominance channels are then high-pass filtered and combined with the luminance channel to form a filtered opponent color domain image.

Las encarnaciones de la actual invención proporcionan sistemas y los métodos para convertir una imagen acromática, higher-resolution a una imagen de la bajo-resolucio'n de errores visibles reducidos. Estos sistemas y métodos abarcan un muestreo del secundario-pixel realizado en una imagen higher-resolution. La imagen muestreada secundario-pixel entonces se convierte a una imagen opuesta del dominio del color que se separe en los canales separados de la luminiscencia y del chrominance. Estos canales del chrominance son entonces haber filtrado high-pass y haber combinado con el canal de la luminiscencia para formar una imagen opuesta filtrada del dominio del color.
