摘要： A sub-mirror which deflects a focal point detection light flux passing through an area off the optical axis of a photographing optical system toward the optical axis and a second deflection member that deflects the focal point detection light flux deflected by the sub-mirror to allow it to advance roughly parallel to the photographic optical axis are provided. A pair of light fluxes achieved by deflecting the focal point detection light flux twice are guided to an image sensor to form a pair of subject images on the image sensor. The focal adjustment state is detected based upon the extent to which the pair of subject images are offset.

摘要： A focal point detection apparatus that includes a sub-mirror constituted of a concave mirror and performs focal point detection in the phase difference detection method is capable of implementing a focal point detection over a wide range. A light flux for focal point detection having passed through a semi-transmissive reflecting member and a reflecting member constituted of the concave mirror described above enters a focal point detection optical system. A correction optical system provided between the semi-transmissive reflecting member and the reflecting member constituted of the concave mirror corrects an offset of the direction along which the light flux for focal point detection advances caused by the reflecting member constituted of the concave mirror, in conformance to the image height at the focal point detection position. By utilizing this correction optical system, it becomes possible to reduce the size of the focal point detection apparatus while assuring a large focal point detection area.

摘要： A focus adjustment device that eliminates unnecessary driving of a shooting lens after the shooting lens has already been driven near to an in-focus position. In a focus adjustment device, information related to the defocus amount of the shooting lens is detected based on output signals corresponding to the light intensity distribution of a object image from a pair of photo-electric conversion arrays. The focus adjustment device includes a focus detection circuit to determine the confidence level of the detected information based on predetermined determination criteria and a lens driving device to drive the shooting lens based on the detected information when the information of the focus detection device is accepted as having a sufficient confidence level. However, to prevent erroneous driving of the lens, such as when the object moves out of a focusing field or when the object reverses direction, the probability of rejecting the information of the focus detection on the basis of an insufficient confidence level increases. This occurs when information indicating that the occurrence of a defocus amount exceeding a predetermined range is detected by the focus detection circuit after the shooting lens has previously been determined to have been driven within permissible parameters of an in-focus position.

摘要： A focus detection device permits accurate focus detection within a short length of time. The detection is quick even if there is an error between the output signal strings of a pair of image sensors when the photo lens is in the focused condition. A pair of effective signal strings is extracted from a pair of output signal strings of a pair of photoelectric conversion arrays. The extraction of the pair of effective signal strings is based on a numerical value relating to an error amount between the output signal strings when the photo lens is in the focused condition. The focus adjustment condition of the photo lens is calculated based on the pair of effective signal strings.

摘要： The light having passed through a photographing lens is directed in a form of one pair of optical images to each of one pair of image sensors. The electric charge accumulated in one pair of image sensors is output in the form of the output signal trains. The photographing lens is driven on the basis of an operation result which has been calculated based on the output signal trains and judged to be reliable. The reliability judgment standard for the operation result representing the focus condition is set loose when the electric charge accumulation has been made while the photographing lens is stopped or is set more strictly when the electric charge accumulation has been made while the photographing lens is being driven.

摘要： An optimum focus detection algorithm range is established in the focus detection area corresponding to the subject pattern. The method includes establishing a first region on the photoelectric conversion array; computing the contrast of the subject image in the first region based on the output signal strings of a plurality of photoelectric conversion elements contained in the first region; establishing a portion of the first region as a second region; and computing the contrast of the subject image in the second region based on the output signal strings of a plurality of photoelectric conversion elements contained in the second region. Subsequently, either the first region or the second region must be determined as the focus detection algorithm range based on the contrast of the first region and the contrast of second region. The focus adjustment condition of the shooting lens is computed based on the output signal strings of the first region or the second region, whichever is selected as the algorithm range.

摘要： A defocus amount is accurately determined within the photo field. As applied to a focus state detection device, DC reduction filter process data is computed without completely extracting the DC component of the signal string output from an image sensor. The DC reduction filter process data is divided into three regions, and a determination is made as to whether focus state detection is possible for each region. When the determination is negative, a determination is made as to whether focus state detection is possible for all regions of first filter process data that extracts high frequency components. When the determination is negative, a determination is made in a similar manner as to whether focus state detection is possible on the basis of second filter process data and third filter process data. When the determination has been made that focus state detection is possible for all regions with one of the filter process data, a standard block is set, a weighing coefficient is set for each block on the basis of this standard block, the defocus amount of each block is altered, the defocus amounts are combined, and a final defocus amount is determined.
