According to these techniques, a display device is configured to determine whether an image to be displayed by the display device has become static. In response to identifying such a static image, the display device may operate in a static image mode. According to the static image mode, the display device may read a current frame of image data, modify the current frame of image data to generate a modified frame of image data with a reduced size, and store the modified image data in memory. The display device may read the modified image data from memory to present the static image, which may reduce power consumption of the display device.

  • Patent number: 10078877
    Abstract: The invention provides a method and system for embedding a watermark in a digital image and recovering the watermark from the digital image. The method includes representing the plurality of binary bits in the watermark using a plurality of symbols, wherein each symbol of the plurality of symbols represents at least two binary bits. The plurality of symbols are then transformed into a plurality of pseudo noise (PN) sequences, wherein a symbol transformed into a PN sequence represents one or more PN sequence vectors from a set of PN sequence vectors. Once the transformation is done, the plurality of PN sequences are embedded in the digital image to generate a watermarked image. During recovery, the watermark is recovered from the watermarked image by identifying the plurality of PN sequences in the watermarked image for recovering the corresponding plurality of symbols associated with the watermark.

  • Patent number: 10074014
    Abstract: Innovations in the identification or classification of features in a data set are described, such as a data set representing measurements taken by a scientific instrument. For example, a task-specific processing component, such as a video encoder, is used to generate task-specific metadata. When the data set includes video frames, metadata can include information regarding motion of image elements between frames, or other differences between frames. A feature of the data set, such as an event, can be identified or classified based on the metadata. For example, an event can be identified when metadata for one or more elements of the data set exceed one or more threshold values. When the feature is identified or classified, an output, such as a display or notification, can be generated.

  • Patent number: 10075637
    Abstract: An electronic device has a power saving function that reduces an amount of consumed power in response to a non-operating period, in which there are no operations from a user, reaching a predefined amount of time. The electronic device displays a time setting screen for setting a time in a display unit and sets the time in accordance with an operation accepted when the time setting screen is being displayed in the display unit, and carries out control such that an amount of time until the power saving function is executed is extended to be longer when the time setting screen is being displayed than when the time setting screen is not being displayed.

    Abstract: A method for generating feature maps by using a device adopting CNN including feature up-sampling networks (FPN). The method comprising steps of: (a) allowing, if the input image is obtained, a down-sampling block to acquire a down-sampling image by applying a predetermined operation to an input image (b) allowing, if the down-sampling image is obtained, each of a (1-1)-th to a (1-k)-th filter blocks to acquire each of a (1-1)-th to a (1-k)-th feature maps by applying one or more convolution operations to the down-sampling image and (c) allowing each of up-sampling blocks to receive a feature map from its corresponding filter block, to receive a feature map from its previous up-sampling block, and then rescale one feature map to be identical with the other feature map in size, and to apply a certain operation to both feature maps, thereby generating a (2-k)-th to a (2-1)-th feature maps.

    Abstract: A system and method for facilitating inhibiting banding in video data, in part by anticipating when banding may occur given certain encoder parameters. An example method includes receiving an input stream of video data; extracting feature information characterizing the stream of video data; using a feed-forward neural network to process the feature information to estimate when a particular block of the stream of video data will exhibit an artifact when encoded using certain Quantization Parameters (QPs); incorporating the indication into metadata associated with the stream of video data; and transferring the stream of video data and metadata to a video encoder. In a more specific embodiment, the feature information includes color information and texture information, and the neural network includes a feed-forward neural network that includes a classifier with a sigmoid activation function, and which has been trained using a cross-entropy cost function.

  • Patent number: 10021411
    Abstract: A scalable coding system codes video as a base layer representation and an enhancement layer representation. A base layer coder may code an LDR representation of a source video. A predictor may predict an HDR representation of the source video from the coded base layer data. A comparator may generate prediction residuals which represent a difference between an HDR representation of the source video and the predicted HDR representation of the source video. A quantizer may quantize the residuals down to an LDR representation. An enhancement layer coder may code the LDR residuals. In other scalable coding systems, the enhancement layer coder may code LDR-converted HDR video directly.
