  • Patent number: 11323676
    Abstract: One limitation of traditional imaging systems is that they are only programmed to correct for a single color of illuminant in a scene. In multi-illuminant scenes, the detected illuminant color may correspond to some mixture of scene illuminants. This may lead to incomplete color correction, wherein, e.g., the dominant illuminant is corrected for but the color cast caused by secondary illuminants is still visible, or an at least partially visible color cast remains from multiple of the scene illuminants. Thus, the techniques disclosed herein comprise: obtaining an image of a scene; generating an illumination map for the obtained image; dividing the values in the illumination map to determine a number of estimated illuminant regions, wherein each region corresponds to at least one estimated illuminant present in the captured scene; estimating a white point for each region; and applying white balancing operations, based on the estimated white points for each region.

  • Patent number: 11164037
    Abstract: A system and method for resolving an ambiguity between similar objects in an image is disclosed. A three dimensional representation of a room is generated, and objects in the room are identified from an image of the room are identified. A determination is made that at least two objects are visually similar, and a position of the two objects is ambiguous. At least one question based on the determined ambiguity is programmatically generated based on information known about the room, and is phrased such that the ambiguity can be resolved by an answer to the question. Based on the answer received one of the objects is selected. At least one property of the selected object is modified based upon the selection of one of the at least two objects.

  • Patent number: 11138761
    Abstract: An image processing apparatus to measure a color of an object based on a measurement target image obtained by imaging the object includes an acquisition unit, a derivation unit, and a calculation unit. The acquisition unit acquires the measurement target image and a reference image different from the measurement target image. The derivation unit derives a reference color based on an imaging parameter used in imaging of the measurement target image, an imaging parameter used in imaging of the reference image, and a pixel value of at least one pixel in the reference image. The calculation unit calculates, with reference to the reference color, a color evaluation value of at least one pixel corresponding to the object in the measurement target image.

  • Patent number: 11138699
    Abstract: The present disclosure relates to systems, methods, and non-transitory computer readable media that utilize context-aware sensors and multi-dimensional gesture inputs across a digital image to generate enhanced digital images. In particular, the disclosed systems can provide a dynamic sensor over a digital image within a digital enhancement user interface (e.g., a user interface without visual elements for modifying parameter values). In response to selection of a sensor location, the disclosed systems can determine one or more digital image features at the sensor location. Based on these features, the disclosed systems can select and map parameters to movement directions. Moreover, the disclosed systems can identify a user input gesture comprising movements in one or more directions across the digital image. Based on the movements and the one or more features at the sensor location, the disclosed systems can modify parameter values and generate an enhanced digital image.

    Abstract: Multi-color flash with image post-processing that uses a camera device with a multi-color flash and implements post-processing to generate images is described. In one aspect, the multi-color flash with image post-processing may be implemented by a controller configured to control a camera and flashes of at least two different colors. The controller may be configured to cause the camera to acquire a first image of a scene while the scene is being illuminated with the first flash but not the second flash, then cause the camera to acquire a second image of the scene while the scene is being illuminated with the second flash but not the first flash, and generate a final image of the scene in post-processing based on a combination of the first image and the second image.
