    摘要: In an endoscope for displaying an image of an object on a monitor screen, a static induction transistor (SIT) image sensor having a number of light receiving elements is arranged at a light emitting side of an image guide bundle. In order to eliminate dead spots appearing in the displayed image due to broken fibers in the image guide bundle, pixel signals of light receiving elements corresponding to the dead spots are formed by interpolation with the aid of pixel signals derived from light receiving elements adjacent to the relevant light receiving elements to be interpolated. As an interpolation function, for example, an average of the pixel signals derived from the adjacent light receiving elements is used. The addresses of the light receiving elements corresponding to the dead spots are stored previously in a PROM during a manufacturing stage. In this manner, the interpolated image of the object having an excellent image quality can be displayed on the monitor.

    摘要: In a single-lens reflex camera having an objective lens, a focusing screen and a view finder, a photodetector array is arranged to receive a central part of an object image formed by the objective lens and a focusing condition of the objective lens is detected by calculating an evaluation function from image signals supplied from the photodetectors. A presetting dial for selecting given photodetectors whose image signals are used for detecting the focusing condition is provided at such a position that a part of the dial is exposed to the outside through an opening formed in a rear wall of a camera body at a position underneath a film winding lever. A light emitting diode array is provided on the focusing screen so as to be seen by a user through the view finder. Only desired light emitting diodes are lighted on under the control of a signal supplied by the dial to indicate the region of the photodetector array which is used for detecting the focusing condition.

    摘要: A method of detecting focusing conditions used for optical machinery is disclosed. The focusing conditions of an optical image projected onto photodetector arrays arranged on both sides of the focal plane with a certain optical distance are detected based on an evaluation function representing a sum of absolute values of differences between output signals of adjacent photodetectors. When a value of a first evaluation function represented by the largest absolute value is less than a predetermined threshold a second evaluation function represented by a sum of the maximum and next largest absolute values is used thereby detecting the focusing conditions for a graded image.

    摘要: In a method and apparatus for detecting focus condition of an imaging optical system, the focus condition is detected in accordance with a combination of two different detection methods such as an image sharpness detection and an image lateral shift detection by using first and second light receiving element arrays for the image sharpness detection and a third light receiving element array for the image lateral shift detection. For making the construction of the apparatus compact and simple, these light receiving element arrays are formed on the same semiconductor substrate. Further a light flux dividing prism and a lenticular lens array are formed integrally with each other. According to the focus detection method of the present invention, it is possible to detect the focus condition for various kinds of subjects accurately over a wide range by using both the image sharpness detection and image lateral shift detection even in a range near an in-focus position.

    摘要: A focus condition of an objective lens is detected on the basis of a lateral shift of two images formed by first and second light fluxes which are transmitted through right- and left-hand halves of the lens, respectively. In order to separate the first and second light fluxes, there is arranged an array of triangle prisms each having first and second surfaces which are inclined symmetrically with respect to the optical axis of lens by a critical angle so that one of the light fluxes is transmitted through the one of the surfaces, but is totally reflected by the other surface of each prism. The first and second light fluxes transmitted through the prisms are received by an array of light receiving elements in such a manner that the first and second light fluxes are selectively received by odd and even numbered light receiving elements, respectively.

    摘要: In order to effect an automatic focus control in an image pick-up apparatus, a photography lens for forming an image of the object onto a two-dimensional solid state image sensing device is arranged in a fixed position, while the two-dimensional solid state image sensing device is arranged movably in the optical axis direction of the photography lens, and the image sensing device is moved in accordance with a focusing error signal detected by a focusing condition detecting circuit having an additional light receiving element mounted on the same substrate as the image sensor but discrete from and operating independently of the image sensor. Since the light and small solid state image sensing device is moved for the focus control instead of the heavy and large photography lens, it is possible to perform the focus control in a prompt manner and to make a mechanism for driving the image sensing device small and simple.
