  • Patent number: 11503204
    Abstract: A method includes capturing an image using a content capture device with an initial image setting. The image includes a plurality of pixel groups, and a pixel group can have one or more pixels. A plurality of edge pixel groups is identified and then classified into two subsets. A first subset of saturated edge pixel groups includes edge pixel groups that have at least one neighboring pixel group with an image intensity exceeding a saturated intensity value. A second subset of non-saturated edge pixel groups includes edge pixel groups that have no neighboring pixel groups with an image intensity exceeding a saturated intensity value. An adjustment value to the image setting is determined based on a total number of saturated edge pixel groups and a total number of non-saturated edge pixel groups. An updated image is captured with an updated image setting based on the adjustment value.

  • Patent number: 11477395
    Abstract: Apparatus and methods for stitching images, or re-stitching previously stitched images. Specifically, the disclosed systems in one implementation save stitching information and/or original overlap source data during an original stitching process. During subsequent retrieval, rendering, and/or display of the stitched images, the originally stitched image can be flexibly augmented, and/or re-stitched to improve the original stitch quality. Practical applications of the disclosed solutions enable, among other things, a user to create and stitch a wide field of view (FOV) panorama from multiple source images on a device with limited processing capability (such as a mobile phone or other capture device). Moreover, post-processing stitching allows for the user to convert from one image projection to another without fidelity loss (or with an acceptable level of loss).

  • Patent number: 11470263
    Abstract: A control section sets an exposure timing and an exposure period for imaging pixels for acquiring an imaging picture and light intensity detection pixels for detecting intensity of illumination light individually by an imaging section. A correction gain calculation section calculates a flicker correction gain for each of the imaging pixels on the basis of pixel signals generated by the imaging pixels and pixel signals generated by the light intensity detection pixels. A flicker correction section uses the flicker correction gain for each imaging pixel calculated by the correction gain calculation section to perform flicker correction of the imaging pixel. Accordingly, an imaging picture can be obtained on which the influence of fluctuation of the intensity of emission light is reduced irrespective of the positional relationship between an illumination apparatus and an imaging object.

  • Patent number: 11451718
    Abstract: Alternating Current (AC) light sources can cause images captured using a rolling shutter to include alternating darker and brighter regions—known as flicker bands—due to some sensor rows being exposed to different intensities of light than others. Flicker bands may be compensated for by extracting them from images that are captured using exposures that at least partially overlap in time. Due to the overlap, the images may be subtracted from each other so that scene content substantially cancels out, leaving behind flicker bands. The images may be for a same frame captured by at least one sensor, such as different exposures for a frame. For example, the images used to extract flicker bands may be captured using different exposure times that share a common start time, such as using a multi-exposure sensor where light values are read out at different times during light integration.

  • Patent number: 11394930
    Abstract: Architectures and techniques are presented that can record video data and wireless communication device data. Signals from sources outside a field of view of a camera recording the video data can be filtered. Such can affect a shielding technique in which a signal shielding apparatus is adjusted in orientation based on an orientation of a camera device. Techniques are further presented to synchronize, according to time, video data and device data. Such synchronization can allow for improved correlation between visual objects (e.g., recorded by the camera) and radio objects (e.g., recorded by a transceiver). For example, visual techniques can be employed to estimate distance/locomotion of a visual object, whereas signal strength metrics can be used to estimate distance/locomotion of a radio object, and the relationship between the two can indicate a strong correlation that a particular device ID is linked to a particular visual object and vice versa.

  • Patent number: 11381754
    Abstract: A camera control section (21) fixes among parameters for photographing which are set in a camera (1), another parameter than exposure time, and causes the camera (1) to photograph a photographing target area while changing the exposure time. An image acquisition section (11) acquires N (N?3) images of the photographing target area acquired by photographing by the camera (1). A model generation section (100) extracts for each pixel position, pixel values of a same pixel position from the N images, and generates a model indicating for each pixel position, a relationship between exposure times and pixel values, based on the extracted pixel values of the same pixel position and an exposure time at a time of photographing of each of the N images. A luminance value calculation section (52) calculates a luminance value for each pixel position, using the generated model and a luminance coefficient.
