摘要： A focus control circuit (34) which controls the focus of a video camera is provided with a horizontal-direction evaluation value generating circuit (62) which generates a plurality of evaluation values for the horizontal direction, a vertical-direction evaluation value generating circuit (62) which generates a plurality of evaluation values for the vertical direction, and a microcomputer (64) which performs a prescribed operation upon receiving the evaluation values for the horizontal and vertical directions. The circuit (62) generates evaluation values based on a plurality of combinatorial conditions of evaluation windows and pass filters for the generation of evaluation values. The microcomputer (64) judges the direction of movement of a focusing lens (12) by weighting the evaluation values with weight data determined for every combinatorial condition. Thus, the direction of movement of the lens (12) is measured accurately.

The microcomputer (64) detects the changes of the evaluation values generated in accordance with the movement of a focus lens (12) and finds the position of the lens (12) at which the evaluation values become relative maximums. When the lens (12) is further moved to a position which is apart from the position at which the evaluation values become the relative maximums by a distance equal to a predetermined times the depth of focus of the lens (12) and the evaluation values generated in accordance with this movement continuously decrease, the microcomputer (64) recognizes the relative maximum position as the absolute maximum point of the evaluation values and judges the position of the lens (12) corresponding to the relative maximum position as the in-focus position. Therefore, the focus of the video camera can be controlled at a high speed because the movement of the lens (12) for searching the absolute maximum point is reduced to a minimum.

摘要： A camera device comprising a motor (9) and a driving circuit (10) both of which drive a focusing lens (2), a motor (11) and a driving circuit (12) both of which drive a zoom lens (3), a motor (13) and a driving circuit (14) both of which drive an iris (4), a CPU (16) which has a memory (15) and gyros (20 and 21). Camera setting conditions such as the focus value, the zoom value, the iris value, etc. corresponding to the orientation theta of the camera device are stored in a storage means beforehand. The image of a subject is picked up by the camera device on the camera setting conditions stored in the memory means. If the image is picked up with a camera angle theta which is not stored in the memory means, the camera setting conditions are found by interpolation in accordance with the orientation theta of the camera device. In other words, the camera setting conditions are automatically changed in accordance with the camera angle theta . Thus, smooth focus-follow can be realized.

摘要： An area detecting circuit (38) receives all picture element data about image pick-up signals from an encoder (37) and selects the area in which the picture element data coincident with the color of a preset target object exist, from among (128) divided areas. A CPU (4) receives the picture element data existing in the selected area from a frame memory (39) and prepares an object information table showing the coordinate position of the object having the picture element data of the color coincident with that of the object. Then the CPU (4) determines the present coordinate position of the object based on the data related to the preceding field stored in a target object history table. The CPU (4) supplies to a focus control circuit (34) an offset value used for changing the center position of a window for detecting an evaluated value from the data representing the coordinate position of the object. The circuit (34) calculates a plurality of evaluated values from a newly set window and generates a control signal used for controlling focus.
