  • Patent number: 11778321
    Abstract: An apparatus including an image capturing section for capturing an image of an object, a lens for causing the image of the object to be formed on an image sensor, and an operation section for acquiring photographing conditions including a focus movement amount and a number of images to be photographed from a user. The lens and the photographing unit are controlled to sequentially acquire the number of images to be photographed by discretely displacing a focal length by the acquired focus movement amount. Whenever an image to be photographed is acquired, a combining map indicative of a combining ratio of respective pixels at same positions in all of the acquired images is calculated, and a combined image is generated based on all of the acquired images according to the combining map and sequentially displayed by superimposing information on the combining map thereon.

  • Patent number: 10694096
    Abstract: An image pickup apparatus includes an optical system and at least one processor executing instructions to: control the optical system to pick up images while changing a focus position; combine; and detect feature points of the images picked up by the optical system and use the feature points of two images to calculate a conversion coefficient for positioning. In the controlling, in a case where the focus positions of the two images are adjacent to each other and the conversion coefficient of the two images does not satisfy a predetermined condition, image pickup is performed again with a method for controlling change of the optical system, and in the combining, two images in which the conversion coefficient satisfies the predetermined condition and focus positions of which are adjacent to each other among the images picked up by the optical system are combined.

  • Patent number: 10445909
    Abstract: An image processing apparatus detects a positional displacement between a predetermined area cropped from adjacent images, among a plurality of images, based on at least one of angular velocity information and posture information of an image sensor, calculates an amount of a rotation component required for compositing the adjacent images, and sets a predetermined threshold based on the at least one of the angular velocity information and the posture information. The apparatus corrects the predetermined area based on the predetermined threshold if the amount of the rotation component is greater than the predetermined threshold, and corrects the predetermined area based on the calculated amount of the rotation component if the amount of the rotation component is equal to or less than the predetermined threshold. Then, the apparatus generates a wide angle image by compositing the plurality of corrected predetermined areas cropped from the plurality of images.
