[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image pickup apparatus which can obtain a minute change as a reproduced continuous image without image blur when a very fast moving object is photographed.

[0002]

2. Description of the Related Art FIG. 10 is a block diagram showing a conventional image pickup apparatus using, for example, an interline CCD as an image pickup element. In the figure, 301 is a photoelectric conversion element that is two-dimensionally arranged in the vertical and horizontal directions, and 302 is a vertical transfer CCD, which is arranged vertically in the vicinity of the photoelectric conversion element and accumulated in the photoelectric conversion element. The signal charge is transferred in the vertical direction. Reference numeral 303 denotes a transfer gate, and each photoelectric conversion element is connected to the vertical transfer CCD via the transfer gate. A horizontal transfer CCD 304 is connected to the final stage of the vertical transfer CCD and outputs the signal charge sent from the vertical transfer CCD as a signal for one horizontal scanning period.
Reference numeral 305 is an amplifier for amplifying the output of the horizontal transfer CCD 304. A signal processing circuit 306 converts the signal from the amplifier 305 into a television signal, for example, an NTSC signal. Reference numeral 307 is a television signal output terminal. 308 is a drive pulse generation circuit, which includes a transfer gate,
Clock pulses φ _T , φ _{V1 to} φ _V4 and φ _{H1 to} φ _H4 are sent to the vertical transfer CCD and the horizontal transfer CCD. 309
Is a system control circuit, which is a signal processing circuit 306,
It outputs an operation command signal to the drive pulse generation circuit 308. Reference numeral 310 denotes a display device (viewfinder) for monitoring the television signal of the output terminal 307, 31
Reference numeral 1 is a drive circuit of the viewfinder 310.

Next, the operation will be described. FIG. 11 is a diagram showing a standard image pickup operation waveform of the conventional image pickup apparatus. When the transfer gate pulse φ _{T of} B is applied to the transfer gate 303 in the field period (1/60 seconds) shown in A,
Through the transfer gate 303, the photoelectric conversion element 3
The signal charge accumulated in 01 is transferred to the vertical transfer CCD. Therefore, the signal charge accumulated in the photoelectric conversion element is reset, and from that time until the next transfer gate pulse φ _T is applied again as shown in C, that is, about 1 field period (in this example, 1/6 for NTSC
A signal corresponding to incident light is accumulated in the photoelectric conversion element 301 for 0 seconds.

The signal charges thus transferred to the vertical transfer CCD are clock pulses φ _V (4
Phase clock pulses φ _{V1 to} φ _V4 , but for simplicity φ
₍ Denoted as _V ) to the final stage of the vertical transfer CCD 302. Then, it is sequentially transferred to the horizontal transfer CCD 304 for each horizontal scanning period (1H).

Here, the number of horizontal transfer clock pulses φ _H (consisting of four-phase clock pulses φ _{H1 to} φ _H4 , not shown) for each 1H is equal to the number of horizontal photoelectric conversion elements. By generating and applying to the horizontal transfer CCD 304, the signal charges are transferred to the output section, and an image pickup output as shown by E is obtained.

That is, the signal charges accumulated in one field period are sequentially output as a signal in the next field period. In other words, it is equivalent to obtaining a still image signal with a shutter speed of 1/60 second. The image pickup signal is amplified by the amplifier 305 and is supplied to the output terminal 307 as a television signal by the signal processing circuit 306.
Further, the television signal is supplied to the viewfinder through the drive circuit 311, and is displayed on the monitor.

When a television signal obtained in the standard image pickup operation state as described above is recorded and reproduced on a magnetic recording / reproducing apparatus or the like, if the subject is a fast moving object, the slow reproduction or still reproduction shows the image quality. Blur occurs.

In order to reduce such image blurring, high-speed shooting described below is performed. In the high-speed shooting mode, the transfer gate pulse φ _T and the vertical transfer clock pulse φ _V from the drive pulse generating circuit 308 are changed from the standard operation by a command from the system control circuit 309 of FIG. The charge storage time of 301 is changed to 1/1000 second, for example. FIG. 12 shows an example of operation waveforms at this time.

First, as shown by G, a first transfer gate pulse φ _T1 is applied to the transfer gate to transfer the electric charge accumulated in the photoelectric conversion element 301 to the vertical transfer CCD 302, and at the same time, as shown by H, The conversion element 301 is reset. Next, a high-speed reverse transfer pulse is generated in a number corresponding to the number of photoelectric conversion elements 301 arranged in the vertical direction like I and applied to the vertical transfer CCD 302. As a result, the charges transferred to the vertical transfer CCD 302 are transferred in the opposite direction to the normal direction and at high speed, and the charges are transferred to the horizontal transfer CCD 30.
4 is discharged to the outside of the vertical transfer CCD 302 without being sent to 4.

After the unnecessary charges are discharged to the outside at high speed in this way, as shown in G, the second transfer gate pulse φ _T2 is applied to the transfer gate 303 1/1000 seconds after the first transfer gate pulse φ _T1. . As a result, the accumulated charges are transferred to the vertical transfer CCD 302 as indicated by a of H in the photoelectric conversion element 301 that has been reset. After this, the same operation as in the standard imaging state in the previous term is performed, the signal charges are transferred in the vertical transfer CCD 302 and the horizontal transfer CCD 304, and the imaging signals are sequentially output from the output section as indicated by J, and the amplifier 305 and the signal processing circuit are output. It is supplied to the output terminal 307 as a television signal via 306. This operation is performed once for each field, and thereafter, the same operation is repeated for each field.

By such an operation, the above-mentioned 1/1000
You will get a shutter speed of seconds. This makes it possible to reduce blurring of a subject moving at high speed.

[0012]

Since the conventional image pickup apparatus is configured as described above, it is possible to capture an object only once in a specific period within one field in the high-speed shooting state and to obtain the other Can not be captured.
Therefore, we photograph the movement of the subject, record it and throw it,
Even with still playback, there is a problem that it is not possible to see finer movements.

The present invention has been made in order to solve the above problems, and an object of the present invention is to provide an image pickup apparatus which can be disassembled more finely than in the prior art, particularly when shooting a fast-moving subject. To aim.

In this case, the fixed signal is inserted into the joint of the partially transferred image pickup signals.
