摘要： Systems and methods for controlling operation of an electronic display are provided. One embodiment describes an electronic display, which includes a display driver that writes image frames to pixels of the electronic display with a first refresh rate or a second refresh rate; and a timing controller that receives a plurality of image frames from an image source, in which the plurality of image frames are displayed on the electronic display to play video content; detects a cadence with which the plurality of image frames are received from the image source; and, based at least in part on the cadence of the plurality of image frames, instructs the display driver to write each of the plurality of image frames either as a single image frame at the first refresh rate or an image frame at the first refresh rate followed by a repeat of the image frame at the second refresh rate.

摘要： A pull-down pattern detection portion detects a pull-down pattern in an input image on which pull-down has been performed. Based on the pull-down pattern and on a first frame frequency that is a frame frequency of the input image, a frame frequency calculation portion calculates a second frame frequency that is a frame frequency of an original image before the pull-down has been performed on the input image. The present technology can be applied to an image processing device that performs frame rate conversion of the input image on which pull-down processing has been performed using a predetermined pull-down pattern.
