Title (EN) DYNAMIC THRESHOLD BASED ERROR DIFFUSION
(FR) DIFFUSION D'ERREUR À BASE DE SEUIL DYNAMIQUE
Abstract: front page image
(EN) In some examples, dynamic threshold based error diffusion may include determining whether a pixel associated with a pattern to be printed includes a lighter tone or a darker tone compared to an adjacent pixel. In response to a determination that the pixel associated with the pattern to be printed includes the lighter tone or the darker tone compared to the adjacent pixel, a firing threshold may be respectively increased or decreased to respectively decrease or increase a likelihood of printing of the pattern.
(FR) Dans certains exemples de l'invention, une diffusion d'erreur à base de seuil dynamique peut consister à déterminer si un pixel associé à un motif à imprimer comprend un ton plus clair ou un ton plus foncé par rapport à un pixel adjacent. En réponse à la détermination que le pixel associé au motif à imprimer comprend le ton plus clair ou le ton plus foncé par rapport au pixel adjacent, un seuil de déclenchement peut être augmenté ou diminué respectivement pour réduire ou augmenter respectivement une probabilité d'impression du motif.
