摘要： An interchangeable lens video camera system which can stably focus on a main target object under any conditions of the object or the environment. The camera system includes a lens assembly detachably attached to a camera for photoelectrically converting incident light to sense an image and output an image signal. The camera system further includes a zoom lens and a focus lens controlled on the basis of an automatic focus evaluation value and data associated with exposure which are received from the camera while referring to a lens cam data unit which stores locus information of the zoom lens and the focus lens in advance. The interchangeable lens video camera system allows for the reduction of blurring and degradation of image quality.

摘要： A focus detecting system for effecting automatic focusing by detecting the in-focus position of a focusing lens and driving the focusing lens to this position. This system has a signal processing means supplied with a video signal from image pick-up means to output a signal related to the in-focus state, a detection means for detecting the position of a focusing lens for forming an image in the image pick-up means, when the signal output from the signal processing means is processed, and a calculating means for calculating the presupposed in-focus position of the focusing lens from at least two groups of items of data on the signal outputted from the signal processing means and on the position of the focusing lens supplied from the detection means. Each time the deviation of the present position of the focusing lens from the presupposed in-focus position is calculated, the focusing lens is driven to move to an extent smaller than the deviation, thus being focused.
