Abstract: 一种液晶面板亮度视角调节方法、装置、系统及显示装置，该方法包括以下步骤：基于液晶面板当前画面的亮度值，检测液晶面板的亮度视角，得到对应当前画面的实际亮度视角值（S210）；在实际亮度视角值小于亮度视角阈值时，基于预设步长调节液晶面板的正负极性驱动电压，得到正负极性驱动电压与亮度视角之间的关系式（S220）；基于关系式处理实际亮度视角值与亮度视角阈值之间的差值，得到目标驱动电压值（S230）；根据目标驱动电压值，调节液晶面板的正负极性驱动电压，实现液晶面板的亮度视角调节（S240）。能够在不改变像素设计的情况下，实现对液晶面板的亮度视角调节，节约了成本，简化了改善液晶设备的亮度视角过程，从而提高液晶面板的亮度视角改善效率。

Abstract: Devices and methods for automatic application of mapping functions to video signals based on inferred parameters are provided. In one example, a method, including initiating display of content based on a video signal being processed by a device, is provided. The method may further include in response to at least a first change in an intensity of ambient light or a second change in a color of the ambient light subsequent to the initiating of the display of the content based on the video signal, selecting a first mapping function applicable to pixels corresponding to frames of the video signal based at least on a first inferred parameter from a selected machine learning model. The method may further include automatically applying the first mapping function to a first plurality of pixels corresponding to a first set of frames of the video signal.

Abstract: A method for the delayed processing of image data captured by a wrist-wearable device is provided. The method includes receiving, at a wrist-wearable device, image data having a first resolution. The method includes, responsive to receiving the image data having the first resolution, storing the image data on the wrist-wearable device. The method further includes downscaling at least a portion of the image data to produce downscaled image data having a second resolution and presenting, on the wrist-wearable device, the downscaled image data having the second resolution. The method further includes receiving a request to send a representation of the image data to a device distinct from the wrist-wearable device. Responsive to the request, the method includes causing image-processing algorithms to be applied to the stored image data such that processed image data is generated and made available at the distinct device.

Abstract: A display device dynamically determines a duration of the illumination period for a display frame to adjust an average brightness of a display device as the framerate dynamically changes. The display device includes a backlight unit (BLU) for providing light for displaying an image, a plurality of pixels for modulating the light provided by the BLU, and a controller circuit for controlling the BLU. The controller circuit measure a duration of a previous frame and determine a duration for an illumination period of a current frame based on the measured duration of the previous frame. The control circuit then controls the BLU based on the determined duration of the illumination period for the current frame.

Abstract: Eyewear including a projector having a variable feedback loop controlling a forward current delivered to a colored light source. The colored light source is configured to generate a colored light beam to generate a displayed image. The variable feedback loop in one example has a variable resistance to selectively generate a high brightness image when the eyewear is operated outside, or in a high ambient light setting, and to selectively generate a nominal brightness image when the eyewear is operated inside. A controller selectively controls the drive current delivered to the colored light source to control the brightness mode of the image.

Ferner weist die Vorrichtung eine Flinterleuchtungseinheit (20) zum Aussenden von Flinterleuchtungslicht in Richtung auf die Rückseite (22) der Anzeigeeinheit (12) zur Flinterleuchtung derselben und eine einstellbare transreflektive Schicht (24) zwischen der Flinterleuchtungseinheit (20) und der Anzeigeeinheit (12) auf. Die einstellbare transreflektive Schicht (24) weist ein Array von Segmenten (28) auf, von denen jedes zur Einstellung des Grades an Transmission und/oder an Reflektion durch ein elektrisches Steuersignal ansteuerbar und damit dimmbar ist. Der Kontrast von an der Anzeigefläche (18) dargestellter Information ist einstellbar durch mittels der Ansteuerung der Segmente erfolgendes Dimmen derjenigen Pixel der Anzeigeeinheit (12), die in Ausrichtung mit dem oder den betreffenden Segmenten (28) angeordnet sind und diesem oder diesen zugeordnet.
