Abstract: A video signal processing apparatus for correcting vibration effects in a video camera that has a CCD image pickup device having a number of lines greater than the number of lines of the standard NTSC television system. The lines used to generate the image are shifted during the vertical blanking interval to correct for vibrations of the video camera, and the overflow charges which are caused by transferring the CCD image pickup device at a high speed during the blanking period are absorbed into a semiconductor drain element arranged in parallel with the horizontal transfer register of the CCD image pickup device. Defective pixels in the image pickup device are compensated by storing the addresses of defective pixels and interpolating at those positions, during vibration correction the addresses of the defective pixels are shifted to correspond to the amount of vibration correction. A read clock and a write clock for the line memory that is used to perform the vibration correction in the horizontal direction are set to line-locked clock signals of different frequencies, thereby preventing deterioration of the picture quality upon vibration correction. The window used to detect optical information for automatic camera control is also shifted in accordance with the shift amount used to perform vibration correction.

Abstract: A camera shake correcting apparatus comprises a variable angular prism (7), a microcomputer (20) serving as a means for driving the variable angular prism (7), actuators (6) and (15), vertical angle sensors (8) and (16), angular velocity sensors (1) and (10) for detecting an angular velocity caused by a camera shake, and damping coils (26) and (32). The variable angular prism (7) is driven by a signal which results from subtracting detected results of the vertical angle sensors (8), (16) and the angular velocity sensors (1), (10) from detected results of the angular velocity sensors (1), (10). The position signal from the vertical angle sensor is subtracted from the detected signal obtained from the angular velocity sensor when camera shake occurs. The prism is driven by a signal which results from subtracting rotational angular velocity signals detected by a damping coil from the subtracted result. Therefore, a nonlinearity of the prism can be alleviated, i.e., the prism can be driven smoothly. Also, the phase margin of the servo characteristic can be increased. Thus, the camera shake correcting apparatus can be made resistant to the fluctuation of elements in its mass-production and a dependency of temperature characteristics.

Abstract: A video camera has an image shift amount detector (64, 66, 68, 70, 72) which detects the amount of an image shift by the use of field correlation of the image information outputted from an image pick-up device (52, 54). The image information is corrected by means of the output of the image shift amount detector (64, 66, 68, 70, 72) in an image shift corrector (74, 76, 78, 80), and then converted into video signals representing consecutive odd and even fields with a cycle of a field in video signal converter (84), so that the image shift can be corrected.
