2. Description of the Related Art An image pickup apparatus forms an image of light from a subject on an image pickup device using a lens, and converts incident light into an electric signal by a photoelectric conversion element such as a photodiode of the image pickup device.
The time period in which the photoelectric conversion is performed is, for example, 1/60 second corresponding to one field period in the case of a standard television. If the imaging apparatus moves relative to the subject due to camera shake while the photoelectric conversion is being performed, a subject image is formed on the imaging device while moving at 1/60 second intervals. In order to correct the movement caused by the camera shake, a method of using a captured video signal by shifting the horizontal and vertical positions by the amount corresponding to the movement caused by the camera shake is conventionally known.

FIG. 8 shows a configuration diagram of a conventional image pickup apparatus using a camera shake correction method.

An output signal obtained from the image sensor 1 is subjected to signal processing such as formation of a luminance signal and a color signal in a video signal processing circuit 2 to form a color video signal. 3 is written. The motion detecting section 4 calculates the color video signal written in the image memory 3
Alternatively, a motion caused by camera shake is detected from a motion signal from the motion detection element 5. The motion signal 22 obtained from the motion detection unit 4 controls the read control unit 23, and the read control unit 23 sets the read position of the color video signal written in the image memory 3 based on the motion signal in the horizontal and vertical directions. To read from the position after the movement due to camera shake to eliminate camera shake.

FIG. 9 is a diagram showing a method in which the read control unit 23 reads a color video signal written in the image memory 3 based on the motion signal. The image-capturable area 24 of the image sensor is wider than the standard image-capturing area 25 of the camera. In the image memory 3 of FIG. 8, the color image signals of all the subject images appearing in the imageable area 24 of the image sensor of FIG. 9 are written. In the stationary state without camera shake, the subject indicated by the reference numeral A is imaged in the standard imaging area 25. When the subject image is moved from the stationary state to the position indicated by the reference sign B due to camera shake, the reading control unit 23 A color video signal in a range indicated by the imaging area 26 at the time of camera shake correction in FIG.
Read from

In the image pickup area 26 at the time of camera shake correction, the horizontal and vertical positions of the subject image indicated by reference numeral B in the image pickup area are the same as the horizontal and vertical positions of the object image indicated by reference sign A in the standard image pickup area 25. Has been made.

As a result of this reading, the position of the subject image indicated by the symbol B in the imaging area 26 at the time of camera shake correction is
The position is the same as the position of the subject image indicated by the symbol A in the standard imaging area 25, and the movement of the subject due to camera shake is corrected, and the movement due to camera shake is eliminated.

In FIG. 8, the video signal processing circuit 2
Is the same even after the read control unit 23. Further, as shown in FIG. 10, without using an image memory, the motion detection unit 4 controls the drive circuit 27 so that the horizontal and vertical start positions of the drive signals of the image sensor 1 are shifted according to the motion. Devices are also well known.

[0009]

In the above-mentioned prior art, the image of the (N + 1) th field is moved by the camera shake with respect to the image of the Nth field of the image repeatedly picked up at a predetermined cycle. When the image is picked up, the read position of the (N + 1) th image is aligned horizontally and vertically with the image of the Nth field so that the target subject image remains at a fixed position in the screen.

However, as described above, incident light from a subject is photoelectrically converted by a photoelectric conversion element such as a photodiode of an image pickup element, and a time period in which this photoelectric conversion is performed is, for example, one field in the case of a standard television. It is 1/60 second corresponding to the period. When camera shake occurs, the subject image formed on the image sensor moves while the photoelectric conversion is being performed. Therefore, the subject image indicated by reference symbol A shown in FIG. The photoelectric conversion is performed while continuously moving to the position of the subject image indicated by, and “blur” occurs in the moving direction of the image in the subject image indicated by the symbol B.

For this reason, in the prior art in which the target subject image is merely stopped at a fixed position in the screen, the position of the image in which this "blur" has occurred is merely adjusted for each field. There is a disadvantage that "blur" in one screen cannot be corrected and image quality deteriorates.

Further, in an electronic still camera that uses a solid-state image pickup device and captures only one image of a subject image, it is impossible to apply a conventional technique of correcting camera shake using a plurality of images. Accordingly, similarly, there is a disadvantage that “blur” in one screen cannot be corrected and image quality deterioration cannot be corrected.

An object of the present invention is to provide a method for correcting a camera shake of a solid-state image pickup device and a solid-state image pickup device, which eliminate "blurring" of an image due to the movement of a camera shake.
