摘要： A camera system which is capable of performing highly accurate focusing in a short time by using two kinds of AF methods, is disclosed. The camera system calculates the target driving amount of the focusing lens based on the result of detection by a first focus detection unit, and performs a first driving control to drive the focusing lens toward a position corresponding to the target driving amount and a second driving control to drive the focusing lens based on the result of detection by the second focus detection unit. When the remaining driving amount to the target driving amount of the focusing lens by the first driving control becomes a predetermined amount, the camera system switches from the first driving control to the second driving control without stopping the focusing lens.

摘要： A camera system which controls the driving of a focus lens through overlap control with a high degree of accuracy, is disclosed. The camera system comprises a lens apparatus with an image-taking optical system and a camera on which the lens apparatus is mountable. The camera system comprises a focus detection unit detecting a focusing state of the image-taking optical system, a driving unit driving the focus lens unit, and a controller controlling the driving speed of the focus lens unit and controls the focus detection unit to perform a focus detection operation at least once while the focus lens unit is moved. The controller sets the driving speed of the focus lens unit at the time of at least a final focus detection operation while it is moved toward an in-focus position, to a speed decelerated from the driving speed before the final focus detection operation.

摘要： The present invention discloses a camera system comprising: a first focus detection unit, which detects the focusing condition of an image-taking optical system; a second focus detection unit, which detects the focusing condition of the image-taking optical system at a higher precision than the first focus detection unit; and a control circuit, which controls a stepping motor for driving a focus lens. The control circuit performs closed loop control for driving the stepping motor based on the output of a rotation detector, which detects the rotation phase of the stepping motor, when controlling the stepping motor using the information based on the output of the first focus detection unit, and performs open control for driving the stepping motor a predetermined number of steps at a time, when controlling the stepping motor using the information based on the output of the second focus detection unit. The autofocus process is thereby made high in speed and high in precision at the same time.
