Abstract: An electronic endoscope apparatus has a light source, a pixel luminance detector, a division setter, an average block luminance calculator, a peak-luminance determiner, a representative luminance calculator, and a brightness adjuster. The division setter divides the subject image into a plurality of blocks composed of given pixels. The average block luminance calculator calculates a plurality of average block-luminance-levels. The peak-luminance determiner compares the average block-luminance-levels with each other in order to determine a substantially maximum average block-luminance-level from the plurality of average block-luminance-levels as a peak luminance level. The representative luminance calculator calculates a representative luminance level indicating a brightness of the subject image. The brightness adjuster adjusts the brightness of the subject image in accordance with the representative luminance level.

Abstract: A switching mechanism of a lens barrel includes a stationary barrel having a stop groove; a lens holding ring, a distance adjustment ring and an AF/MF switching ring, each positioned concentrically with the stationary barrel. The AF/MF switching ring is prevented from rotating relative to the stationary barrel by engagement of the engaging member with the stop groove while a driving force is transferred from a power source to the distance adjustment ring to move the lens holding ring along the optical axis when the AF/MF switching ring is in the AF position. Rotation of the AF/MF switching ring is transferred to the distance adjustment ring to move the lens holding ring along the optical axis while the driving force is prevented from being transferred from the power source to the distance adjustment ring when the AF/MF switching ring is in the MF position.

Abstract: Disclosed is a lens, which has a convex surface, a concave surface and a flange that is formed around the lens to be projected in a radial direction perpendicular to an optical axis and to be continued from the convex surface. The flange is provided with a groove formed on the side of the convex surface that extends from the outer edge of the convex surface toward the outer edge of the flange. When the lens is pulled up from a solution of coating material, the unnecessary solution that collects at a lower area of the convex surface drips from the lens through the groove. This prevents a formation of a puddle on the convex surface.

Abstract: A lens barrel includes a rotatable ring, a non-rotatable outer annular member having a circumferential groove located on the inner peripheral surface thereof, an advancing/retracting mechanism configured to move the rotatable ring along the optical axis between movement limits of the rotatable ring, a rotational projection located on the outer peripheral surface of the rotatable ring such that the projection is engaged in the circumferential groove when the rotatable ring is moved to one of the movement limits, and a stopper which is insertable into and removable from the circumferential groove at an intermediate point between opposite ends of the groove. The stopper limits the range of rotation of the rotatable ring relative to the outer annular member by engaging the rotational projection in a state where the stopper is positioned in the circumferential groove, and the stopper stops preventing the range of rotation of the rotatable ring in a state where the stopper is positioned outside the circumferential groove.

Abstract: In a scanning optical system including a polygon mirror for dynamically deflecting N laser beams corresponding to N color components and an imaging optical system for converging the laser beams into spot beams on N photosensitive drums respectively, the imaging optical system includes: a front lens group for converging the laser beams principally in a main scanning direction while deflecting the beams to deviate from its optical surface reference axis; and N rear lens groups for converging the laser beams principally in an auxiliary scanning direction respectively. The rear surface of the front lens group and front surfaces of the rear lens groups are formed as two-dimensional polynomial aspherical surfaces. Concretely, the rear surface is formed as a step-like optical surface having N discrete areas of different heights. By the system, the laser beams are separated sufficiently to match the intervals between the photosensitive drums without the need of long optical paths, without deteriorating the scanning performance, and without the need of using mirrors which cause color misregistration and increase costs.
