Equipment, machines, and methods for transitioning between a first-line multiple image display including content with a first dynamic range and a second-line multiple image display including at least some content with a second dynamic range different from the first dynamic range.

Abstract

The invention relates to devices, methods and machines for processing graphics, such as producing smooth transitions between multiple first-order and multiple second-order images of different dynamic ranges (for example, standard dynamic range (SDR) images and high dynamic range (HDR) images). The exemplified method generally involves the step of using high frame rates for the transition interval to allow the image attributes to change incrementally. The attributes can include brightness (hair color, luminance), blood gamut, tonal mapping, among others. For example, during the transition interval, a subset of HDR images is displayed at a higher second frame rate (e.g., 120 Hz) than the frame rate based on HDR images (e.g., 30 Hz). Simultaneously, the brightness level (as well as other aspects) of the display is adjusted progressively from SDR brightness to IIDR brightness during the transition interval on the subset of HDR images.
