Abstract: A control device controls projection by a plurality of projection units having different projection ranges. A control unit projects, by the plurality of projection units a first image in which a content is disposed on a first projection range having the projection ranges of the plurality of projection units. An acquisition unit acquires first attribute information associated with the content and indicating whether an aspect ratio is made to be changeable or is maintained in a case in which a size of the content is adjusted. The control unit projects a second image in which at least a part of the contents is disposed on a second projection range, and, in a state in which projection is performed by a projection unit except a part of the plurality of projection units, adjusts the size of the content in generation of the second image based on the first attribute information.

Abstract: A zoom lens forms an intermediate image at a position conjugate to a reduction side imaging plane and forms the intermediate image again on a magnification side imaging plane. The zoom lens includes a plurality of lens groups including at least two movable lens groups, which move by changing spacings between the groups adjacent to each other in a direction of an optical axis during zooming, at a position closer to the reduction side than the intermediate image. Among the plurality of lens groups, a final lens group closest to the reduction side has a positive refractive power, and remains stationary with respect to the reduction side imaging plane during zooming. The zoom lens satisfies predetermined conditional expressions (1) and (2) about the focal lengths of the movable lens groups.

Abstract: The present invention provides a projection zoom lens and a projection display apparatus including the projection zoom lens. The projection zoom lens substantially has a negative first lens group, a positive second lens group, a positive third lens group, a positive fourth lens group, and a positive fifth lens group in order from a magnification side. During magnification change, the first lens group and the fifth lens group are fixed, and the second lens group, the third lens group, and the fourth lens group are moved while changing a mutual distance in an optical axis direction. The fourth lens group includes two sets of negative-positive cemented lenses formed by cementing one negative lens and one positive lens in order from the magnification side. A predetermined conditional expression relating to the most magnification side of the fourth lens group and the negative-positive cemented lens of the most reduction side is satisfied.

Abstract: The present invention provides an imaging device and a focusing control method capable of performing reliability determination of a phase difference AF at high speed. A phase difference AF processing unit (19) performs a correlation operation with respect to detection signal groups in first pairs P1, and performs a correlation operation with respect to detection signal groups in second pairs P2. A system control unit (11) compares a difference between a first correlation amount M1 which is a minimum correlation amount between the detection signal groups in the first pairs P1, among obtained results of the correlation operation with respect to the first pairs P1 and a second correlation amount M2 which is a minimum correlation amount between the detection signal groups in the second pairs P2, among obtained results of the correlation operation with respect to the second pairs P2 with a threshold value TH, to thereby determine a reliability of a focusing control based on the phase difference AF method.
