摘要： A focus detecting apparatus is disclosed which includes a focusing optical system for forming an object image on a predetermined focal plane and photoelectric devices disposed before and behind the focal plane at substantially equal distances from the plane. The photoelectric devices detect the focus states of the object images formed thereon respectively. The focus state of the object image on the focal plane is detected depending on whether or not the focus states on the photoelectric devices are equal to each other. According to the invention such a focus detecting apparatus further includes a mask for gradually decreasing the quantity of light incident upon the photoelectric devices in the direction away from the center of the incident beam. Under the action of such a mask, the focus states of object images before and behind the predetermined focal plane at substantially equal distances from the focal plane are made approximately equal to each other.

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： A focus detecting system detects an image formation state of an image of an object by processing a time-serial output from a photoelectric transducer element through a high-pass filter. In order to suppress the outputs from the high-pass filter corresponding to the time-serial signal at the initial moment of light reception by the photoelectric transducer element or immediately thereafter, an amplifier is provided which performs the initial setting of the high-pass filter. The input and output ends of the amplifier are connected to parts of the high-pass filter, and the output impedance of the amplifier may be changed in response to a signal from an external source.

摘要： In a photoelectric transducer device such as a solid state image pick-up device or sensor having a great number of minute photoelectric transducer elements with their image-receiving surfaces of certain shape arranged in a one-dimensional or two-dimensional manner so that brightness informations of the various individual sections of the object image are sensed by the respective photoelectric transducer elements which then produce outputs in the form of time-sequential signals, the above-described shape of the image-receiving surface area of each of the minute photoelectric transducer elements is made to be such that, as the distance from the center of the image receiving area toward the margin increases, the proportion of the area of a progressively farther concentric zone of the same width is decreased. The shape takes such a form or such characteristics as to be represented by a sampling function or other analogous functions with respect to the scanning direction of the image pick-up device.

摘要： A focal point detection system for detecting the focus adjusting state of an image forming lens during its focusing operation on an object is disclosed. The system comprises a focus detection circuit which produces a detection output that varies with focusing of the lens on the object; a plurality of display elements are provided for display of the focusing state of the lens; and a display control circuit which enables the display elements to display a greater number of focusing states than the number of these display elements through selective combinations of these elements on the basis of the output of the focus detection circuit. The system is capable of displaying intermediate focusing states such as a slightly near-focus state, a slightly far-focus state, and the like in addition to in-focus, near-focus, and far-focus states, so that the focusing state can be displayed stepwise in a detailed manner.
