As shown in the figure. This electronic still camera is configured so that a subject image (not shown) is formed on the imaging surface of an image sensor 3 by a lens 1, but normally (when the subject is not being imaged) the shutter 2 is closed and the shutter 2 is closed. Incident light from the subject is blocked and is not guided to the image sensor 3.

型化・低コスト化を阻害する一因となっている。When photographing an object, when the release switch 7 is pressed, the shutter 2 is opened for a required period of time set by the shutter speed setting device 6, and incident light from the object is guided to the image sensor 3. A charge corresponding to this incident light is generated and accumulated in the image sensor, and this charge is read out as a video signal in synchronization with the synchronization signal from the synchronization signal generator 6, and is recorded in the recording device 4 to produce a still image. The shooting of - is completed. Conventional electronic still cameras with the above configuration use a method of controlling the period of incidence of incident light, similar to conventional cameras using silver halide film, to obtain instantaneous images of the subject. In addition, a shutter device is required to control the blocking and passing of incident light, which is one of the factors that hinders miniaturization and cost reduction of devices.

A photoelectric conversion element array 21 as disclosed in Japanese Patent No. 104377. Charge absorbing row 24.Charge transfer element row 22.
This is a solid-state image sensing device in which a part of the readout register is constituted by a 23° charge storage region 26.
第2図において、被写体像はレンズ1によって常に固体

従来例におけるシャッターが閉じた状態となっている。Normally (when the subject is not being photographed), the solid-state image sensor 8 is operated by a control signal from the operating condition control signal generator 12 to absorb all the charges generated in the photoelectric conversion element array 21 corresponding to the subject image. 24, and due to the same constraints, no incident light from the subject is guided to the solid-state image sensor 8, that is, the shutter in the conventional example shown in FIG. 1 is in a closed state. There is.

Rising time t2 of VB (in this example, the first vertical blanking signal) (waveform a in Figure 4) At time t3, which is an exposure time TB set by the exposure time setting device 11, an operating condition control signal is generated. The control signal from the device 12 changes from a Low state to a High state, and the solid-state image sensor 8 is driven by the drive circuit 13 so that the charge generated in the photoelectric conversion element array 21 is accumulated. Specifically, the charge absorbing operation of the charge absorbing column 24 of the solid-state image sensor 8 is stopped.

A pulse as shown in FIG. 4C is applied to an electrode (not shown) that transfers the charge of a horizontal picture element column to the adjacent charge transfer element column 22, and the photoelectric charge of either an odd or an even horizontal picture element column is applied. The charge of the conversion element is transferred to the charge transfer element array 22. Here, in order to simplify the explanation later, an odd horizontal pixel array is assumed. This charge is then transferred to the storage region 26 and temporarily accumulated by applying a transfer pulse to the charge transfer element array 22 and the storage region 26 for a period from t to t6 as shown in FIG. 4d. . After this charge transfer is completed, the charges in the photoelectric conversion elements of the remaining even-numbered horizontal pixel columns are transferred by applying the pulse shown in FIG. The data is transferred to the element array 22 and temporarily stored there.

は生じない。Furthermore, considering the signal charges that form the video signals of the first and second fields, the accumulation time, that is, the exposure time, of the signal charges that form the video signals of the first field is Ts, and the video signal of the second field is The accumulation time of the formed signal charges is TS+TW, which is a different value. However, TW is the time t2 when the signal charges forming the first field video signal are transferred from the photoelectric conversion element array 21 to the vertical transfer element array 22, and the time t2 when the signal charges forming the second field video signal are transferred from the photoelectric conversion element array 21 to the photoelectric conversion element array 22. This is the time difference from time t6 at which the data is transferred from the vertical transfer element array 21 to the vertical transfer element array 22. Therefore Tw
No problem occurs when Ts is sufficiently small, but Tw
When it can no longer be ignored with respect to Ts, the reproduced image becomes unsightly if the video signals of the first and second fields are recorded as they are. To prevent this, in the signal processing circuit 9,
The amplification degree A1 for the video signal of the first field and the amplification degree A1 for the video signal of the first field,
If the amplification degree A2 for the video signal of the field is made different and maintained in the following relationship, the first output from the signal processing circuit 9
.. The video signal of the second field has no level and no problem occurs.
以上で、被写体の撮影・記録が完了し、シャッター無し
