  • Patent number: 10182188
    Abstract: An image pickup apparatus which is capable of performing automatic adjustment of black balance properly without the need to have a member for fully shielding light. A diaphragm of a lens barrel and an ND filter, which is provided separately from the diaphragm, adjust the amount of light incident on an image pickup device that picks up an image of a subject. Whether the automatic adjustment is possible in present image pickup environment is judged based on evaluation values of a picked-up image obtained in a state where the amounts of incident light are maximized by respective ones of the diaphragm and the ND filter, and a predetermined judgment threshold value which is determined based on a range over which the amount of incident light is adjustable by the diaphragm and a range over which the amount of incident light is adjustable by the ND filter.

  • Patent number: 10009551
    Abstract: An image processor merges images from a plurality of cameras including applying spatially-varying gains over images from individual cameras to obtain a consistent effective where the images are stitched together despite the cameras possibly having different camera exposures. The image processor can adjust the camera exposures to improve stitching results. In addition to gain modification, the image processor can also modify the images for other artifacts, such as veiling glare and make those less visible at the seams of images. The image processor also can take into account constraints on gain changes and optimize camera parameters to minimize stitching artifacts. Using a cost function, the image processor can optimize for constraints on camera exposure that would otherwise result in camera exposure differences that would themselves cause visible artifacts.
