A projection optical system that performs enlargement projection of an image on a display device surface formed of a plurality of pixels onto a screen surface, in which pixel shift by less than a pixel pitch is performed on the screen surface in a vertical direction, a horizontal direction, an oblique direction, or a vertical and horizontal directions, and in which conditional formulae (1) and (2) below are fulfilled over the entire image range: (1)|&#x394;RG|&#x2266;0.5 d and (2)|&#x394;BG|&#x2266;0.5 d, where d represents the amount of pixel shift (&#x3e;0), &#x394;RG represents lateral chromatic aberration in the direction of pixel shift of colored light R having a wavelength of 640 nm with respect to colored light G having a wavelength of 546 nm, and &#x394;BG represents lateral chromatic aberration in the direction of pixel shift of colored light B having a wavelength of 450 nm with respect to the colored light G having a wavelength of 546 nm.

Projection optical system

The invention concerns an image-capturing apparatus and an imager. The image-capturing apparatus includes the imager in which a plurality of circuit cells are two-dimensionally aligned, and an electronic charge, photo-electronically converted from a received light and stored in each circuit cell, can be discharged from an arbitral circuit cell. The imager includes first group circuit cells to generate electronic charges corresponding to the pixels of the image including a subject, and second group circuit cells to generate electronic charges corresponding to an amount of light coming from the subject, the electronic charges further being converted to a detected value. In the imager, at least one of two operations of halting a generating-action of the electronic charges in the first group circuit cells and discharging the electronic charges from the first group circuit cells is performed, when the detected value exceeds a threshold value.

A lens-fitted film unit package, including: a lens-fitted film unit further including: (a) a preloaded photographic film; (b) a camera lens; (c) a shutter; (d) a diaphragm; and (e) an EV value switcher for switching the EV value of the lens-fitted film unit between the first EV value and the second EV value, which is greater than the first EV value; and a packing material; in which the lens-fitted film unit is packaged in the packing material under the condition that the EV value of the lens-fitted unit is switched to the second EV value.

Lens-fitted film unit, lens-fitted film unit package and method of manufacturing lens-fitted film unit package

A lens-fitted film unit includes: a main body; a photographic lens provided in the main body, having an aperture value; an aperture provided in the main body; a shutter provided in the main body, having a shutter speed; a photographic film loaded in the main body, having image frames each including an unexposed portion and a pre-exposed portion on which a latent image has been formed; and a masking member for masking the pre-exposed portion of the photographic film when a photographing operation is conducted. The latent image has been formed on the photographic film with a same exposure amount as that obtained when an object to be photographed having a brightness of not less than 10 and not more than 12.5 in terms of light values in which a photographic film whose ISO sensitivity is 100, is exposed to light with an aperture value of the photographic lens set by the aperture and with the shutter speed of the shutter.

Lens-fitted film unit

A lens-fitted film unit including a main body; a photographic film, pre-loaded in the main body; an electronic flash unit; a shutter unit; a camera lens; and a diaphragm. In the lens-fitted film unit, a guide number of the electronic flash unit, a T-number determined from the camera lens and the diaphragm and a shutter speed of the shutter unit are determined so that A is not more than 8.5 when A represents an EV value of a reference exposure amount of the lens-fitted film unit under a stroboscopic photographing state minus 1.5; and intensity of a latent image, formed on the photographic film under the condition that a reference reflection panel being placed at a predetermined distance between 2-3 m from the lens-fitted film unit is illuminated by the electronic flash unit without other lights in the stroboscopic photographing state, corresponds to intensity of a latent image obtained under a photographing condition of photographing luminance not more than A&plus;5.0 in EV value.

An optical system for recording or reproducing of information to or from an optical information recording medium, includes a light source, a coupling lens for converting a diverging light emergent from the light source to a converging light, and an objective lens for further converging the converted converging light and for focusing on an information recording surface of the optical information recording medium. A lateral magnification M.sub.c of the coupling lens on an image side for a light source side and a numerical aperture NA.sub.o on the light source side of the coupling lens satisfy the following expressions respectively, -7.0.ltoreq.M.sub.c .ltoreq.-0.5 and 0.06.ltoreq.NA.sub.o .ltoreq.0.21.

An optical system for recording or reproducing of information to or from an optical information recording medium, includes: a light source; a coupling lens for converting a diverging light emergent from the light source to a converging light; and an objective lens for further converging the converted converging light and for focusing on an information recording surface of the optical information recording medium. A lateral magnification of the objective lens in which a wavefront aberration within a Marechal criterion is minimum, satisfies the following conditional expression,

A single-use camera which includes: a film winding knob, capable of rotating in the winding direction, for winding a film so as to feed the film frame by frame; a reversion-preventing member, having an engagement with the film winding knob, for preventing the film winding knob from rotating in the opposite direction to the winding direction; a releasing member for releasing the engagement of the reversion-preventing member with the film winding knob when the film is wound by the film winding knob so that the noise, generated from the reversion-preventing member, is prevented.
