Abstract: A projection system includes a set of a first projection apparatus and a first imaging unit and a set of a second projection apparatus and a second imaging unit. A first projection range of the first projection apparatus and a second projection range of the second projection apparatus have an overlapping part. A control device of the projection system determines whether or not an operation for an operating part projected to the overlapping part is performed based on a captured image of the first projection range and a captured image of the second projection range, and executes a predetermined control in a case where it is determined that the operation is performed.

Abstract: A projection display device includes an imaging element, a light source, a light valve that modulates light from the light source and emits modulated light in a prescribed polarization state, and an imaging optical system. The imaging optical system includes a first optical system that is used in common in projection and imaging, a second optical system that is used only in projection, a third optical system that is used only in imaging, and a separation member that separates an optical path from the second optical system toward the first optical system from an optical path from the first optical system toward the third optical system. The first optical system comprises a quarter wave plate and a polarizer arranged in a state of transmitting the light emitted from the light valve.

Abstract: An objective optical system for an endoscope consists of a front group, an aperture stop, and a positive rear group in order from an object side. The front group consists of a negative first lens having a smaller absolute value of a curvature radius of a lens surface on an image side than that on an object side, and one or more parallel planar members of which an incidence surface and an emission surface are perpendicular to an optical axis, in order from the object side. The rear group consists of a positive second lens and a cemented lens in which a negative third lens, and a positive fourth lens are joined together in order from the object side and a cemented surface has a concave surface toward the image side. A predetermined conditional expression is satisfied.

Abstract: It is intended to provide an imaging apparatus that enables proper exposure of phase difference detection pixels and thereby makes it possible to perform phase difference autofocusing with high accuracy. A system control unit 11 selects phase difference detection pixels from phase difference detection pixels 51R and 51L existing in a selected phase difference detection area 52 according to a position of the selected phase difference detection area 52 in a row direction X, and determines exposure conditions based on output signals of the selected phase difference detection pixels. A defocus amount calculation unit 19 calculates a defocus amount using output signals of the phase difference detection pixels 51R and 51L existing in the selected phase difference detection area 52 that are part of a shot image signal produced by shooting that is performed by an imaging device 5 under the exposure conditions determined by the exposure determining unit 11.

Abstract: Interpolation precision of phase difference detection pixels is raised. An image sensor (14) is provided with a color filter (30) upon which a basic sequence pattern, formed by disposing a first sequence pattern and a second sequence pattern in point symmetry, is repeatedly disposed. In the first sequence pattern, first filters are disposed on pixels in the four corners and in the center of a square array of 3×3 pixels, second filters are disposed in a horizontal line in the center of a square array, and third filters are disposed in a vertical line in the center of a square array. In the second sequence pattern, the first sequence pattern and the positions of the first filters are the same, while the positions of the second filters and the positions of the third filters have been swapped.
