  • Publication number: 20020102105
    Abstract: A photometry device for a camera is provided with a normal light sensor having a plurality of photometry areas, and a plurality of photometric sensors for colorimetry. A photometry value determining system determines a photometry value at each photometry area in accordance with outputs of the normal light sensor. A colorimetric compensation value determining system determines a color of an object at each photometry area in accordance with the outputs of the photometric sensors for colorimetry, and determines a colorimetric compensation value based on the determined color. An exposure value determining system compensates for the photometry value determined by the photometry value determining system for each o photometry area, and determines an exposure value based on the compensated photometry values. The colorimetric compensation value determining system determines different threshold values, which are used for determining colors at the plurality of photometry areas, for different photometry areas.

  • Publication number: 20020048171
    Abstract: A laser beam emitting unit includes a laser diode, a collimating lens upon which a laser beam emitted by the laser diode is incident, a base plate to which the laser diode is fixed, a lens holder which holds the collimating lens, and a holder support plate via which the lens holder is fixed to the base plate. The holder support plate includes a flat portion which faces the base plate with a gap between the flat portion and the base plate, and at least two leg portions which extend from the flat portion to the base plate in a direction substantially perpendicular to the flat portion. Each of the at least two leg portions includes a claw portion which is deformed to be fixed to the base plate, wherein the gap is maintained between the flat portion and the base plate.
