摘要： An imaging apparatus capable of capturing an in-focus image while moving, and an image composition apparatus capable of generating a high detail composite image are provided. A camera 100 is mounted on an unmanned aerial vehicle 10, and imaging is performed while moving. During imaging, a focusing mechanism included in the camera 100 is controlled, and a focus position is periodically scanned. In addition, during imaging, movement of the unmanned aerial vehicle 10 is controlled such that at least one scanning is performed during movement to a position shifted by an imaging range.

摘要： A lens apparatus includes an aperture stop, configured to form an image via the aperture stop and detachably mountable to a camera apparatus, a storage storing correction data for correcting image data obtained by image pickup by the camera apparatus, with respect to a light amount distribution in the image; and a communication device configured to transmit the correction data to an external apparatus. The correction data includes a coefficient of an n-th order polynomial (n is a non-negative integer) with respect to an image height, which corresponds to each of a plurality of states of the aperture stop. Minimum F-numbers at a wide angle end a telephoto end, focal lengths at the wide angle end and at the telephoto end, and F-numbers corresponding to the correction data are appropriately set.

摘要： An imaging lens is formed from a first group lens having negative power, a second group lens having positive power, a third group lens having negative power, and a fourth group lens having positive power, disposed in order from the subject side to the image side. Letting f be the focal distance for the entire lens system and ff2 the focal distance for the second group lens, 1.0≤ff2/f≤2.0 is satisfied; therefore, the entire length of the lens system can be kept short and image curvature can be suppressed. In addition, each of the subject side lens surfaces and the image side lens surfaces for the second group lens, third group lens, and fourth group lens are provided with aspherical surface shapes; therefore, the imaging lens is constituted to be bright.

摘要： An image capturing apparatus includes: a focus detection unit configured to detect a focus state of an imaging optical system; a reliability determination unit configured to determine reliability of the focus detection; and a control unit configured to control an opening of an aperture of the imaging optical system, wherein the control unit, if the reliability determination unit determines that reliability of the focus detection performed in a state in which the opening of the aperture is controlled to a first aperture opening state is less than a threshold value, changes the aperture to a second aperture opening state in which the opening of the aperture is reduced relative to the first aperture opening state, and wherein the control unit does not change the aperture to the second aperture opening state if a predetermined condition is satisfied.
