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, 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 third optical system includes a first light shielding member that is arranged in the vicinity of a stop position of the third optical system and shields a part of a luminous flux.

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 first optical system on the magnification side, and a second optical system on the reduction side. The intermediate image is formed between the magnification and reduction sides. The second optical system includes two or more movable lens groups, which move by changing spacings between the groups adjacent to each other in a direction of an optical axis during zooming, and two stationary lens groups which remain stationary with respect to the reduction side imaging plane during zooming. One stationary lens group is disposed closest to the reduction side, and has a positive refractive power. Also, a lens group closest to the magnification side in the second optical system has a positive refractive power.

Abstract: An imaging lens is constituted by, in order from the object side to the image side: a front group having a negative refractive power; and a rear group having a positive refractive power. The front group is constituted by two negative lenses. The rear group includes a cemented lens formed by cementing a negative lens and a positive lens having a smaller Abbe's number with respect to the d line (wavelength: 587.6 nm) than the negative lens, provided in this order from the object side to the image side, together.

Abstract: An image capturing apparatus includes: an image capturing element in which a plurality of pixels are formed and arranged and phase difference pixels are formed within an effective pixel region; a photographing lens; and a control unit which analyzes a captured image signal by the image capturing element, obtains a phase difference amount from detection signals of two of the phase difference pixels that make a pair, and performs a focusing control of the photographing lens, in which the control unit calculates, as a sensitivity ratio, a ratio of an integration value of light receiving sensitivity of the phase difference pixel within a range of an incident angle of the photographing lens, and an integration value of light receiving sensitivity of a pixel other than the phase difference pixel, and corrects a deviation in light receiving sensitivity between the two phase difference pixels.
