Abstract: The present invention provides a resin composition for stereolithographic modeling emitting a weak odor, having desirable shape accuracy, and made into a cured product having desirable strength, toughness, and color tone when used for stereolithographic modeling. The present invention relates to a resin composition for stereolithographic modeling, comprising: a polymerizable monomer (A); a photopolymerization initiator (B), and an organic peroxide (C), wherein the polymerizable monomer (A) comprises a (meth)acrylic acid ester compound (A-1) having a viscosity of 1,000 mPa·s or less and a normal boiling point of 270° C. or more and/or a (meth)acrylamide compound (A-2) having a viscosity of 1,000 mPa·s or less and a normal boiling point of 200° C. or more, and the photopolymerization initiator (B) is at least one selected from a (bis)acylphosphine oxide, an ?-hydroxyketone compound, an ?-aminoketone compound, a benzoin alkyl ether compound, a thioxanthone, a ketal, an ?-diketone, and an anthraquinone.

Abstract: A display device includes a frame that includes a front portion, temple portions, and a pad portion, and is mounted on head of an observer, and an image display device attached to the frame. The image display device includes an image forming device, and an optical device on which light emitted from the image forming device is incident and from which the light is emitted toward the observer. One end portion of the optical device is fixed to a temple portion side of the front portion. Other end portion of the optical device is on a pad portion side of the front portion. A light shielding member that prevents external light from being incident on the other end portion of the optical device from above the other end portion of the optical device is attached to the pad portion side of the front portion.

Abstract: An imaging apparatus includes at least one memory and at least one processor which function as: an exposure control unit configured to perform exposure control, so that representative brightness of a high brightness region of an image approaches a target brightness that is set by a user; and a gradation correction unit configured to perform gradation correction to increase a contrast of the high brightness region, by expanding a brightness range of the high brightness region of the image which is captured after performing the exposure control, wherein the gradation correction unit changes degree of the expansion of the brightness range of the high brightness region based on the target brightness.

Abstract: An imaging apparatus includes at least one memory and at least one processor which function as: an acquisition unit configured to acquire a representative brightness of a high brightness region of an image; a setting unit configured to set a target brightness of the high brightness region, based on a display brightness of a display device that displays the image; and an exposure control unit configured to control exposure based on the representative brightness and the target brightness of the high brightness region.
