  • Patent number: 10050071
    Abstract: To obtain an imaging unit, a lens barrel, and a portable terminal which can effectively suppress spring-back of solid-state imaging elements, while facilitating height lowering thereof. An imaging unit includes: a solid-state imaging element; and an imaging lens for forming a subject image on a photoelectric conversion part of the solid-state imaging element. An imaging surface of the solid-state imaging element is curved in a manner that a peripheral side is inclined toward an object side relative to a screen center. The imaging lens constrains the solid-state imaging element to prevent a radius of curvature of the imaging surface from varying. Thus, field curvature, distortion aberration, and comatic aberration are appropriately corrected.

  • Patent number: 7725020
    Abstract: There is provided a monitoring camera apparatus which, while ensuring waterproofness, can perform focus adjustment when a dome cover is mounted. A lens (3) is covered by the dome cover (5) which is removable. A focus adjustment mechanism (9) moves an imaging device (7) in an optical axis direction and thereby performs focus adjustment. A setting button (13) being a focus setting operation unit is arranged in the inner side of the dome cover (5), and operated when the dome cover (5) is mounted. A controller (11) controls the focus adjustment mechanism (9). The controller (11) allows the focus adjustment mechanism (9) to start focus adjustment when a predetermined focus start wait time has elapsed after operation of the setting button (13). The focus start wait time is set according to a standard mounting operation time required to mount the dome cover (5).

  • Patent number: 7237919
    Abstract: The invention provides a range finder capable of carrying out three-dimensional measurement stably for a long period of time. A light pattern is projected on a subject by using a light source array unit in which a plurality of light sources, such as LEDs, are arranged. Even when each LED has a small light quantity, a sufficiently large quantity of light can be projected on the subject by the entire light source array unit, and hence, the three-dimensional measurement can be stably carried out. Also, a plurality of light patterns can be generated by electrically controlling a light emitting state of each LED of the light source array unit.
