摘要： A camera system includes a camera, a shooting field shifting mechanism, a shift amount acquiring unit, and a masking processor that masks a masking target within a captured image flame. The masking processor includes first and second position computing units, and mask area establishing unit. The first and second position computing units compute, based on the shift settings of the shooting field shifting mechanism, first and second relative positions of the masking target relative to the shooting field. The mask area establishing unit establishes a mask area to mask the masking target on the captured image flame, based on the first and second relative positions.

摘要： In a digital video camera according to one aspect of the invention, a black level of a video signal is specified during an initialization process. An autofocusing process obtains an AF evaluation value and a brightness evaluation value at each current position of a compensator lens and updates a maximum AF evaluation value and a corresponding position of the compensator lens based on the obtained data. The autofocusing process also detects an AGC gain, computes an offset value of the AF evaluation value from the detected AGC gain, the obtained brightness evaluation value, and the specified black level, and calculates a threshold value from the computed offset value and the updated maximum AF evaluation value. When the obtained AF evaluation value is less than the calculated threshold value, the lens position corresponding to the maximum AF evaluation value is specified as the focus position. When the obtained AF evaluation value is not less than the calculated threshold value, on the other hand, this series of processing is repeated with a position shift of the compensator lens by a preset number of steps. This arrangement ensures efficient and precise hill-climbing autofocus control in view of the potential influence of high frequency noise in the digital video camera or another electronic camera.

摘要： A video camera constructed according to one aspect of the focus adjustment device moves a focus lens forward and backward and detects peak values of an AF evaluation value of the focus lens in the forward moving direction and in the backward moving direction. The video camera calculates a correction value based on a difference between the peak value of the evaluation value detected in the forward motion of the lens and the peak value of the evaluation value detected in the backward motion of the lens. The video camera corrects the AF evaluation value with the calculated correction value and detects a focused position of the lens based on the corrected AF evaluation value in moving the lens.

摘要： An imaging device moves a zoom lens, so as to change the magnification of an image of a subject, and obtains a near limit position of a focusing lens to the subject at a zoom lens position. When a target position of the focusing lens, which is required to keep the image in focus after the zoom lens is moved, is located on a near side, i.e., on an imaging plane side, of a threshold position determined based on the obtained near limit position, focus control is performed to move the focusing lens and thereby focus. When the target position of the focusing lens is not located on the near side but is located on a subject side of the threshold position, on the other hand, focus control is performed to move the zoom lens to a wider position and subsequently move the focusing lens to focus the image.

摘要： In an imaging device according to one aspect of the invention, an amplitude demand Ac is specified according to a wobbling amplitude Ai required for detection of a hill-climbing direction based on an F value and a wobbling amplitude Ag required for detection of the hill-climbing direction based on an AGC gain. An allowable amplitude Am set for preventing a potential image shake caused by a magnification change with a position shift of a compensator lens in wobbling is specified corresponding to a zoom position and an object distance. When Ac>Am, the control procedure restricts the wobbling amplitude to Am and increases a sampling number of AF evaluation values to be detected at respective positions in wobbling, in order to ensure the sufficient detection performance of the hill-climbing direction. When Ac□Am on the other hand, the control procedure sets Ac to the wobbling amplitude. This arrangement of the imaging device efficiently ensures the sufficient detection performance of the hill-climbing direction for autofocusing control, while effectively preventing deterioration of the quality of a captured image due to the magnification change in the wobbling motion.
