摘要： An automatic focusing optical apparatus comprises an automatic focusing device which automatically controls the focal point of an optical system and is arranged to be operatable in such a manner that, once the optical system is focused on an object, the focal point of the optical system is fixed to be unvarying irrespectively of changes in the distance to the object; a display device which is capable of displaying the in-focus and defocus states of the optical system independently of the automatic focusing device; and control means for allowing the display device to display solely the in-focus state when the automatic focusing device fixes the focal point of the optical system to be unvarying irrespectively of changes in the distance to the object after the optical system is once focused on the object.

摘要： This specification discloses an energizing control of a drive element for driving a motor or the like which drives a focusing lens. The energization is controlled on the basis of the detection of whether or not the position of the focusing lens is within the quasi-in-focus state, and when the continuation of the quasi-in-focus state for a predetermined time period or more is detected, energization of the driving element is stopped.

摘要： A battery checking device for cameras of the type having a booster circuit the output of which is fed as electrical power to a load is disclosed. In the case of the camera of the type described, when the battery voltage is checked at the output of the booster circuit, an accurate checking operation cannot be carried out. The present invention, therefore allows the voltage at the input of the booster circuit to be checked. Since another problem is that the booster circuit, after having been actuated, takes a predetermined time before its operation is stabilized, and the value of voltage as sensed during this time does not provide an accurate representation, the present invention provides that checking of that input voltage begins after the elapse of a predetermined time from the actuation of the booster circuit when the operation of the booster circuit becomes stable. Accordingly, it is made possible to achieve always an accurate and reliable battery checking operation.

摘要： Disclosed is an image sharpness detecting system in which an image formed by an image forming optical system is received by an array of a plurality of optical-electronic transducer elements, and an illumination difference in each individual minute compartment of the above-described image is detected on the basis of the concurrently obtained output signal from a corresponding one of the optical-electronic transducer elements, while all the illumination differences are summed up over the entire area of a sensing region of the above-described image, whereby is obtained a signal representing the degree of sharpness of the image on the above-described array of optical-electronic transducer elements. In this system, the signal representative of the illumination difference in each individual minute compartment of the above-described image is at least non-linearly transformed by utilizing the non-linear characteristics for output versus input of a semiconductor element such as a transistor, and the signal representative of the degree of sharpness of the above-described image is obtained on the basis of the non-linearly transformed signal.

摘要： This specification discloses improvements in the so-called sharpness detection type algorism in which three light receiving means are provided near a predetermined focal plane and forwardly and rearwardly thereof to quantitatively detect the out-of-focus relative to the predetermined focal plane and the sharpnesses of the images at the positions of the three light receiving means are detected. More particularly, it discloses a technique whereby the range in which the amount of in-focus error can be detected is increased by using as a signal for normalizing an error signal a signal indicative of the difference between the sharpness of the image on the light receiving means disposed near the predetermined focal plane and the smaller one of the sharpnesses of the images on the light receiving means at the opposite ends.
