Circuitry For Compensating For Variation In The Brightness Of The Object (epo) Patents (Class 348/E5.034)
  • Patent number: 12192645
    Abstract: A method and a circuitry for exposure compensation applied to a high dynamic range video are provided. The circuitry is adapted to an image-acquisition device. In the method, when a video is received, the pixel values for each of the sequential frames can be obtained. Next, an exposure value ratio between two adjacent frames is obtained. A processor exposure value ratio of an image signal processor can be regarded as an initial exposure value ratio. A fixed adjustment ratio is used to control the image signal processor and an image sensor of the image-acquirement device so as to calculate an exposure value ratio for each of the frames. The exposure value ratio is referred to for performing the high dynamic range compensation for the frames so as to output an HDR video.

  • Patent number: 11696046
    Abstract: Techniques are described for efficient high-resolution output of an image captured using a high-pixel-count image sensor based on pixel binning followed by luminance-guided umsampling. For example, an image sensor array is configured according to a red-green-blue-luminance (RGBL) CFA pattern, such that at least 50-percent of the imaging pixels of the array are luminance (L) pixels. Pixel binning is used during readout of the array to concurrently generate a downsampled RGB capture frame and a downsampled L capture frame. Following the readout, the L capture frame is upsampled (e.g., by upscaling and interpolation) to generate an L guide frame with 100-percent luminance density. An upsampled RGB frame can then be generated by interpolating the RGB capture frame based both on known neighboring RGB information (e.g., from the RGB capture frame and previously interpolated information), as adjusted based on local luminance information from the L guide frame.

  • Patent number: 11610424
    Abstract: Systems and methods are described for registering a fingerprint based on optical fingerprint recognition. A fingerprint recognition window is displayed and a fingerprint frequency of a user fingerprint is analyzed based on reflected light received through the fingerprint recognition window using a fingerprint recognition sensor driven by a pixel binning scheme based on a first binning size. The first binning size may be evaluated based on the fingerprint frequency. If the first binning size is not appropriate for registering the user fingerprint, a second binning size is selected. Fingerprint information of the user fingerprint may be obtained again based on using the fingerprint recognition sensor driven by a pixel binning scheme based on the second binning size.

  • Patent number: 10969272
    Abstract: Methods and systems for modulating a manufactured light source are disclosed. Methods and systems of the present disclosure include sensor assemblies having first and second light sensors to retrieve light spectrum data at a target location, such as from a surface in an interior space at a home, office, or commercial building, that also receives daylight exposure. The first light sensor retrieves the light spectrum data within a spectrum of the manufactured light source. The second light sensor retrieves light spectrum data outside of the spectrum of the manufactured light source, yet within the spectrum of daylight. The light spectrum data is used to define spectral characteristics at the target location, such as a ratio of daylight to the manufactured light source, phase of daylight, and average overall quantity, which are used to maximize light-associated benefits of the spectral composition for the occupants at the target location, such as humans, plants, and animals.
