Abstract

PURPOSE:To improve the mobility and reduce the cost by generating a composite image by putting a video signal and a stored signal together in one machine. CONSTITUTION:When a mode changeover switch is turned to composition mode, a switching circuit 4 is switched so as to output a signal to an image composing circuit 10, and a recording image signal is outputted from an image memory 9 to the circuit 10. When a release button is depressed at this time, the light which is made incident from an optical system 1 is sent to the circuit 10 through an image pickup element 2, a signal processing circuit 3, and the circuit 4. The circuit 10 substitutes the background part of a subject in front of a monochromatic background for the image from the memory 9 and sends the resulting image to a recording circuit 5. Here, the signal is processed, sent to a disk drive 6, and then recorded on a floppy disk through a head. When the mode changeover switch is placed in normal photography mode, the circuit 4 sends the signal directly to the circuit 5 and the image can be recorded on the floppy disk similarly.

FIG. 4 is a diagram illustrating the configuration of FIG. 3.

In FIG. 3, reference numeral 23 is a reproducing device for reproducing a floppy (not shown) on which a main subject image is recorded, and 24 is a reproducing device for reproducing a floppy (not shown) on which a background for composition is recorded. A reproducing device 25 is an image synthesizing device, which processes the reproduction signal output from each of the reproducing device 23 and the reproducing device 24 into a combined signal and outputs it to the recorder 26.

In FIG. 4, 20 is a main subject image, 21 is a background image, and 22 is a composite image obtained by combining the subject image 20 and the background image 21.

Next, the operation of the conventional example will be described with reference to FIGS. 3 and 4. 3 and 4, a player 23 for playing back the floppy on which the main subject image is recorded and a player 2 for playing back the floppy on which the background to be combined is recorded.
Each floppy is put in 4 and a reproduction signal output is sent to the image synthesizer 25. The two signals are processed in the synthesizer 25 and sent to the recorder 26 as a synthesized signal. The image changes in these flows are as shown in FIG.

In FIG. 4, when the main subject image 20 and the background image 21 are input to the synthesizing circuit 10, a synthesized image 22 in which the main subject image 20 and the background image 21 are synthesized is output.

As described above, in the above-mentioned conventional example, when two images are combined, image signal processing is performed so that two videos are recorded and reproduced, both images are combined and recorded again. Therefore, each equipment is separate, resulting in a large-scale system and poor mobility.

Another problem is that separate floppy disks are required for image input and image recording.

Further, in this conventional example, since the main subject image is once recorded on the medium and then reproduced and dubbed, there is a problem that the main subject image is deteriorated in the composite image.

Further, as mentioned above, there is a problem that the cost increases because the number of equipments increases.

The present invention has been made to solve the above-mentioned problems, and includes memory means for storing images,
One device by circuit switching means for inputting a video signal from the image pickup circuit to a circuit other than the recording circuit, and video synthesizing means for synthesizing the signal from the circuit switching means and the signal from the memory means and outputting to the recording circuit. The purpose is to create a composite image in order to increase mobility and reduce costs.

It is another object of the present invention to carry out image input and recording with the same floppy so that the floppy is not taken in and out, and the immediacy is improved.

Another object of the present invention is to reduce the deterioration by directly inputting the main subject image to the image synthesizing means and recording the image.

[0015]

Therefore, in the present invention, a memory means for storing a video, a circuit switching means for inputting a video signal input from an image pickup circuit to a circuit other than a recording circuit, and the circuit switching means. And a video synthesizing unit for synthesizing the video signal input from the memory unit and outputting the video signal to the recording circuit. is there.

In the still video camera according to the present invention, the image is stored in the memory means, the video signal input from the image pickup circuit is input to the circuit other than the recording circuit by the circuit switching means, and the circuit switching means is input by the video synthesizing means. Synthesizes the video signal input from the memory means with the signal input by
Output to the recording circuit.
