    摘要: Various techniques are provided for processing image data acquired using a digital image sensor 90. In accordance with aspects of the present disclosure, one such technique may relate to the processing of image data in a system 10 that supports multiple image sensors 90. In one embodiment, the image processing system 32 may include control circuitry configured to determine whether a device is operating in a single sensor mode (one active sensor) or a dual sensor mode (two active sensors). When operating in the single sensor mode, data may be provided directly to a front-end pixel processing unit 80 from the sensor interface of the active sensor. When operating in a dual sensor mode, the image frames from the first and second sensors 90a, 90b are provided to the front-end pixel processing unit 80 in an interleaved manner. For instance, in one embodiment, the image frames from the first and second sensors 90a, 90b are written to a memory 108, and then read out to the front-end pixel processing unit 80 in an interleaved manner.

    摘要: An electronic device may generate content that is to be displayed on a display. The display may have an array of liquid crystal display pixels for displaying image frames of the content. The image frames may be displayed with positive and negative polarities to help reduce charge accumulation effects. A charge accumulation tracker may analyze the image frames to determine when there is a risk of excess charge accumulation. The charge accumulation tracker may analyze information on gray levels, frame duration, and frame polarity. The charge accumulation tracker may compute a charge accumulation metric for entire image frames or may process subregions of each frame separately. When subregions are processed separately, each subregion may be individually monitored for a risk of excess charge accumulation.

    摘要: In a coding system, an encoder codes video data according to a predetermined protocol, which, when decoded causes an associated decoder to perform a predetermined sequence of decoding operations. The encoder may perform local decodes of the coded video data, both in the manner dictated by the coding protocol that is at work and also by one or more alternative decoding operations. The encoder may estimate relative performance of the alternative decoding operations as compared to a decoding operation that is mandated by the coding protocol. The encoder may provide identifiers in metadata that is associated with the coded video data to identify such levels of distortion and/or levels of resources conserved. A decoder may refer to such identifiers when determining when to engage alternative decoding operations as may be warranted under resource conservation policies.

    摘要: Methods and apparatus for caching reference data in a block processing pipeline. A cache may be implemented to which reference data corresponding to motion vectors for blocks being processed in the pipeline may be prefetched from memory. Prefetches for the motion vectors may be initiated one or more stages prior to a processing stage. Cache tags for the cache may be defined by the motion vectors. When a motion vector is received, the tags can be checked to determine if there are cache block(s) corresponding to the vector (cache hits) in the cache. Upon a cache miss, a cache block in the cache is selected according to a replacement policy, the respective tag is updated, and a prefetch (e.g., via DMA) for the respective reference data is issued.

    摘要: Systems, methods, and non-transitory media are presented that provide for improving color accuracy. An electronic display (12) includes a display region having multiple pixels each having multiple subpixels. The electronic device (10) also includes a display pipeline (36) coupled to the electronic display (12). The display pipeline (36) is configured to receive image data and perform white point compensation on the image data to compensate for a current drop in the display (12) to cause the display (12) to display a target white point when displaying white. The display pipeline (36) also is configured to correct white point overcompensation on the image data to reduce possible oversaturation of non-white pixels using the white point compensation. Finally, the display pipeline (36) is configured to output the compensated and corrected image data to the electronic display (12) to facilitate displaying the compensated and corrected image data on the display region.

    摘要: Systems, apparatuses, and methods for implementing a timestamp based display update mechanism. A display control unit includes a timestamp queue for storing timestamps, wherein each timestamp indicates when a corresponding frame configuration set should be fetched from memory. At pre-defined intervals (810), the display control unit may compare the timestamp of the topmost entry of the timestamp queue to a global timer value (815). If the timestamp is earlier than the global timer value (820), the display control unit may pop the timestamp entry and fetch the frame next configuration set from memory (825). The display control unit may then apply the updates of the frame configuration set to its pixel processing elements (835). After applying the updates, the display control unit may fetch and process the source pixel data and then drive the pixels of the next frame to the display (840).

    摘要: Methods and devices employing circuitry for dynamically adjusting bandwidth control of a display interface are provided. The display interface or image content is dynamically adjusted to support both high-speed image data (e.g., 120 Hz image data) and lower-speed content (e.g., 60 Hz content). For example, in some embodiments, additional pixel pipelines and/or processing lanes may be activated during the rendering of high-speed image data, but not during the rendering of low-speed image data. Additionally or alternatively, high-speed image data, but not low-speed data, may be compressed to render high-speed content over an interface that supports only low-speed content.
