摘要： A zoom optical system (25) is associated with an image sensor (46), which is disposed behind the zoom optical system for picking up an object (6). The zoom optical system is focussed by use of a photoelectric signal from the image sensor. In a setup mode, the zoom optical system is zoomed from a first magnification to a preset magnification. The zoom optical system has been set at the first magnification. The preset magnification is adapted to focussing. The zoom optical system is focussed in accordance with the photoelectric signal generated while the zoom optical system has the preset magnification. The zoom optical system is zoomed back from the preset magnification to the first magnification, while keeping the zoom optical system in-focus. The zoom optical system becomes in-focus at the first magnification in a manner in which the zoom optical system is in-focus at the preset magnification.

摘要： A lens focusing system for a camera. The camera includes a focusing lens that is movable between a first terminus point and a second terminus point. An amount required to move the focusing lens to obtain an in-focus condition is determined, which is used to drive the focusing lens to position the focusing lens at the in-focus condition. A plurality of drive signals are generated in response to the driving of the focusing lens, which are monitored. A monitored position value is established that is based upon the plurality of drive signals monitored by the monitoring means, and the monitored position value is compared with a predetermined position value corresponding to one of the first terminus point and the second terminus point after the lens has been moved by the amount determined to be required to move the focusing lens to obtain the in-focus condition. The focusing lens is then driven in a direction until the focusing lens is prevented from moving when the monitored position value corresponds to a position which is out of a range between the first terminus point and the second terminus point. When the focusing lens has been moved to one of the first terminus point and the second terminus point, the monitored position value is replaced with the predetermined position value.

摘要： A zone for measuring distance is enlarged by adding an area where a contrast ratio is relatively high in the case of the photographing against the light. Thus, the sensitivity for judging a contrast ratio is increased and improper focusing is prevented. The brightness when an evaluative value is a maximum and the brightness at a moment when the evaluative value is not at maximum, for example when it is at a minimum, are compared. If the difference of brightness becomes too large, the maximum evaluative value is ignored and the detection is repeated. The determination of when the difference in brightness is too large is made to be dependent on parameters such as gain of the AGC circuit, gain of the amplifier and iris opening which affect the noise in the evaluative value so as to more accurately judge when the when the maximum evaluative value should be ignored.
摘要翻译：在相对于光的拍摄的情况下，通过添加对比度相对较高的区域来扩大用于测量距离的区域。因此，用于判断对比度的灵敏度增加，并且防止了不正确的聚焦。当评估值为最大时的亮度和当评估值不处于最大值时的亮度，例如当其为最小时的亮度进行比较。如果亮度差太大，则忽略最大评价值，重复检测。亮度差太大时的判断取决于AGC电路的增益，放大器的增益和影响评估值中的噪声的虹膜开度等参数，以便更精确地判断何时应忽略最大评估值。

摘要： An automatic focusing projector has a reflector which includes a semispherical mirror and a semielliptical mirror in combination, and a contrast chart having a contrast pattern associated with the reflector. The first focal point of the semielliptical mirror is identical to the center of the semispherical mirror. The contrast pattern is located between the first and second focal points of the semielliptical mirror. A light source is provided in the vicinity of the first focal point of the semielliptical mirror. The light source can be a white light source, and a colored filter can be positioned forwardly of a projecting lens which forms part of the projector in order to pass light having a wavelength region of low luminosity in which a human eye is virtually insensitive.

摘要： A digital still camera includes an aperture stop opening, a taking lens system, and a CCD pickup element. In a manual focus device, an iris shifting mechanism sets the aperture stop opening in an aperture stop unit with reference to a first light amount gravity center by shifting the aperture stop opening to the right relative to a lens optical axis, and sets the aperture stop opening with reference to a second light amount gravity center by shifting the aperture stop opening to the left. First and second sample pickup data are obtained by the CCD pickup element in the setting of the aperture stop opening at the two light amount gravity centers. A display panel displays first and second sample images according to the sample pickup data, to indicate a present deviation of the taking lens system from an in-focus position in simulation. A focusing ring is externally operable, for moving the taking lens system on the optical axis, and for actuation while the two sample images are checked visually, to position the taking lens system when the two sample images inform a reach to the in-focus position.
