号を取り出している。FIG. 1 is a diagram showing the configuration of a conventional image pickup plate, in which a photoelectric conversion element array 1, a signal switching section 2, a vertical shift register 3,
It also includes a horizontal shift register 4. And column 1 includes a plurality of photoelectric conversion elements la to lf.
Further, a switching control signal is supplied from the terminal 5, and based on this signal, the switching unit 2a switches each signal field from, for example, the photoelectric conversion units la and lb, and sends it to the shift register 3a. Similarly, pixel signals are transferred to shift register 3b,
Sent to 3c. Vertical shift register 3, 3a
, 3b, 3c are sequentially sent in the direction of arrow A, that is, to the horizontal shift register 4, based on control signals from the load control terminal 6 and shift control terminal 7. Next, the pixel signals sent to the horizontal shift register 4 are sequentially shifted in the direction of arrow B based on control signals from the load control terminal 8 and shift control terminal 9, and as a result, a video signal is taken out from the terminal 10. The solid-state image pickup plate shown in FIG. 1 is compatible with the interlaced television system, so signals are extracted field by field as described above.

てしまっていた。したがって、本発明の目的は静止画像
として画像の動き（ブレ）がない画像信号を得ることが
できる固体撮像板を提供することである。Since there is a time difference between these fields, there is naturally some movement in the image, and when the video signal obtained from the solid bran image plate shown in Figure 1 is used as a signal for a still image, the two fields are repeated. There was a drawback of image movement (blur). Incidentally, if the switching in the switching unit 2 is fixed as shown in FIG. 1, the blurring will be eliminated, but the vertical resolution will be lowered, resulting in a still image of poor quality. Therefore, an object of the present invention is to provide a solid-state imaging plate that can obtain an image signal as a still image without image movement (blur).
