    摘要： An optical apparatus detects a visual point of an observer, and reduces the visual axis detection error due to anatomical differences between people, such as the difference in the size of the eye. The apparatus sequentially displays a plurality of marks in a finder, and can calculate a precise visual point position on the basis of errors between the calculated visual point position and the marks when the observer sequentially watches these marks.

    摘要： An optical apparatus includes a projecting optical system for projecting an image of an object in a viewfield onto an image receiving surface. First detecting structure is provided for detecting which position is viewed in the viewfield. Second detecting structure is provided for detecting a defocus for the image receiving surface of the image of the object. Optical system driving structure is provided for driving a portion of the projecting optical system according to the defocus detected by the second detecting structure. A processor is provided for causing the detection by said second detecting structure and the drive by said optical system driving structure to be repeated until the image of the object is focused on the image receiving surface. The processor also causes a first time detection by the second detecting structure to be performed for an object corresponding to a position of a first time detection by the first detecting structure, and causes a second time detection and following time detections by the second detecting structure to be performed for the object corresponding to the position of the first time detection by the first detecting structure.

    摘要： A camera having a line of sight detecting apparatus to detect a line of sight of an eyeball of an observer comprises: a lens device having a movable lens; a detector to detect a moving state of the movable lens in the lens device; and a controller for making the line of sight detecting operation by the visual axis detecting apparatus different from that in the case where the movable lens is not moved when it is detected by the detector that the movable lens has been moved. When a focusing lens as a movable lens is being driven, the controller stops the line of sight detecting operation by the visual axis detecting apparatus or doesn't use the line of sight detection information for the camera control.

    摘要： In an image sensor having a plurality of pixels which photoelectrically convert a subject image, a plurality of pairs of focus detection pixels including first focus detection pixels (SHA) and second focus detection pixels (SHB) are arranged while being distributed. The layouts of the first focus detection pixel (SHA) and the second focus detection pixel (SHB) are switched in pairs of focus detection pixels adjacent in the focus detection direction. Focus detection is performed using image waveforms obtained from the first focus detection pixel (SHA) and the second focus detection pixel (SHB) whose layouts are switched. This reduces focus detection errors generated when the pixels included in the pairs of focus detection pixels receive light fluxes from different portions of the subject.
