Abstract: This document describes systems and techniques directed at zonal attenuation compensation. In aspects, a system includes a graphics processing unit configured to provide image data to a display panel. A zonal attenuation module is configured to combine a zonal attenuation mask with the image data to generate masked image data, the masked image data having a reduced brightness for portions of data corresponding to one or more regions on the display panel based on the zonal attenuation mask. An inverse zonal attenuation module is configured to apply an inverse zonal attenuation mask to the masked image data to reduce a brightness for additional portions of data corresponding to one or more additional regions on the display panel effective to offset increased brightness in the one or more additional regions on the display panel.

Abstract: Techniques and apparatuses are described that perform frequency compensation for a display. In aspects, a first uniformity of multiple regions of the display can be measured at a reference frequency. The display can then be driven at a second frequency and a second uniformity of the multiple regions of the display can be measured. The differences between the first and second uniformity can then be used to generate a compensation mask. XYZ domain data from the first and second uniformity measurements can be used to generate a color model characterization. The color model characterization can be used to convert the XYZ domain data into RGB data when the display is driven at the second frequency to compensate for the differences in uniformity across the multiple regions of the display.

Abstract: In general, the subject matter described in this disclosure can be embodied in technology for operating a display device that includes a pixel array. A first frame is programmed to the array, while the display device is operating at a first refresh rate, including by scanning the first frame line-by-line to the pixel array at a first scan rate. An indication that the display device is to transition from the first refresh rate to a second refresh rate is received. An intermediate frame is then programmed to the pixel array, including by scanning the intermediate frame line-by-line to the pixel array at an intermediate scan rate. A second frame is then programmed to the pixel array, while the display device is operating at the second refresh rate, including by scanning the second frame line-by-line to the pixel array at the second scan rate.

Abstract: A transcript of a conference (e.g., a video conference, an audio conference, or a telephone call with two or more participants) is processed to extract a conference summary. The transcript includes strings that are associated with respective timestamps and respective speaker identifiers. Speaker segments—sequences of consecutive strings attributed to the same speaker—are identified in the transcript. A speaker segment is selected based on its duration in time and one or more strings are selected from with the selected speaker segment for inclusion in the conference summary. A short video conference summary or a short audio conference summary is then generated using timestamps from the transcript associated with strings (e.g., sentences) that have been selected for inclusion in the conference summary. The short video or audio summary may be presented to users to enable efficient storage and transmission of information from the conference within a unified communications system.

Abstract: A method may include measuring, from a device having a display panel configured to operate at a first refresh rate or a second refresh rate, a difference in luminance of the display panel between the first refresh rate and the second refresh rate for an input gray level. The method may also include applying, based on the measured difference in luminance, a value offset to a default gamma value used by the device for the input gray level when the display panel is operating at the second refresh rate, thereby generating a new gamma value. The method may further include storing, at the device, the new gamma value, where subsequent to the storing, the device is configured to override the default gamma value for the input gray level with the new gamma value when the display panel is operating at the second refresh rate.

Abstract: Systems and techniques directed at dynamic power-saving mechanisms for displaying an image are disclosed. An electronic device determines an image to be displayed and an associated OPR for displaying the image. Based on the determined OPR, the electronic device generates a bionic image. Various mechanisms may be used to generate the bionic image. A display brightness value (DBV) or different blocking areas of the combined image may be used to generate the bionic image. The electronic device combines the image and the bionic image to form a combined image and presents the combined image on an emissive display. The combined image reduces a power expenditure of the emissive display that may otherwise be expended. The combined image may retain a high luminance for a focus area of the combined image while reducing the luminance for the remaining area (e.g., area outside of the focus area) of the combined image.

Abstract: Voicemail spam detection is performed based on content of voicemail messages. The content of an incoming voicemail message is compared to a spam template that includes a representation of a spam voicemail. Spam templates may be generated based on spam indications provided by users for voicemail messages they have received. User indications for sufficiently similar voicemail messages may be aggregated by maintaining a vote count for a spam template that reflects how many times a user has indicated a matching voicemail message is spam. A spam template may also include an occurrence count that reflects how many times voicemail messages matching a spam template have been detected in a telephony system. An incoming voicemail message may be compared to spam templates and, responsive to a match of content and/or a corresponding vote count or occurrence count meeting a condition, the voicemail message may be identified as spam.
