摘要： A camera includes a focus adjusting system; first and second switches for a focus adjusting system and an exposure device; and a controller. If the second switch is operated before the focusing lens group reaches a specified focal length position, the search operation stops and the exposure device activates after the focus adjusting system performs the search operation until an infinite focus position. If the second switch is operated after the focusing lens group reaches the specified focal length position, the search operation immediately stops and the exposure device activates. If the in-focus position is detected by the search operation after completion thereof, the focusing lens group moves to the in-focus position and the exposure device activates. If no in-focus position is detected by the search operation after completion thereof, the focusing lens group moves to the specified focal length position and the exposure device activates.

摘要： A focus detection apparatus includes a lens drive mechanism for moving a focusing lens group, and a controller for detecting a contrast value of the object image and moving the focusing lens group. The controller calculates a difference between maximum and minimum contrast values detected at the different positions of the focusing lens group; compares contrast values at two adjacent lens positions to determine whether the contrast value increases successively and subsequently decreases successively; detects a maximum contrast value, if the contrast value increases successively and subsequently decreases successively; calculates the maximum contrast value via a point of intersection between straight lines of two linear approximation expressions if the difference is equal to or greater than a predetermined value; calculates the maximum contrast value from a quadratic approximation expression, if the difference is smaller than the predetermined value.

摘要： A focus detection apparatus includes a focusing lens group, and a controller. The controller establishes a first predetermined number and a first criterial value if a maximum contrast value and/or minimum contrast value is outside a predetermined range, and a second predetermined number and second criterial value if the maximum and minimum contrast values are within the predetermined range; compares contrast values detected at adjacent positions to determine whether the contrast value of the object image increases once and subsequently decreases by the first or second predetermined number of times; detects a maximum contrast value if the contrast value of the object image increases once and subsequently decreases by the first or second predetermined number of times; determines a difference between the maximum contrast value and a detected contrast value; and selects the maximum contrast value if the difference exceeds the first/second criterial value.
