During a period (T = 4 to 6) during which the information of the child screen corresponding to one frame or more is written to the reduction memory 117 and the write control information 213 of the reduction memory control unit 118 is writing. The output changeover switch control information 209 output from the system control unit 113 is changed, and the output of the camera signal processing unit 102 is output to the video output unit 104 and the shuffling memory 105 as they are. That is, the captured video information is output to the video output unit 104 and the shuffling memory 105.

The compressed information corresponding to an arbitrary frame of the compressed information of one frame or more written in the video memory 109 is transmitted via the video signal processing unit 108 and the recording / reproducing head 112 in accordance with the operation of the operation switch 114. Record.

By selecting and recording compressed information corresponding to an arbitrary frame of one or more still images that have been output and captured, the still image recorded during still image recording and the still image or moving image to be captured next Can be simultaneously displayed on the screen, and information corresponding to a required frame can be arbitrarily selected and recorded from one or more captured still images. At present, the video memory 109 uses a general-purpose 4 Mbit DRAM, and in the case of compressed information, data for three frames can be recorded. Therefore, the present embodiment can be realized with a small change.

In the above description, a VTR block using a video tape as a recording medium has been described as an example of an electronic image pickup apparatus. However, an electronic still camera that stores data in a storage element such as a semiconductor memory may be used. The present invention can also be applied to a TV camera or the like that wirelessly transmits imaged electronic information to another video information processing apparatus without having it.

In the present invention, the camera memory is not described, but may be added as it is.

When the still image recording is not performed, the reduced signal processing unit 116, the reduced memory 117, and the reduced memory control unit 118 may be stopped.

Further, a configuration in which the first and second embodiments are combined may be used. In addition, the information in which the child screen is inserted into the main screen is output to the LCD panel 119. However, instead of the LCD panel 119, a video output terminal is configured to output only information, and other video monitor devices are connected to this video monitor device. It may be connected to the output terminal and displayed.

As described above, according to the present invention, a still image recorded during still image recording is formed by forming and outputting video information in which a child screen is inserted into a part of the parent screen during recording of a still image. And the still image or moving image to be taken next can be displayed on the screen at the same time.

When one frame or more of still image information is fetched, video information in which a one-frame or more child screen is inserted into a part of the parent screen is formed and output. By selecting and recording information corresponding to an arbitrary frame of a still image, a still image recorded and a still image or a moving image to be shot next can be simultaneously displayed on the screen even during recording of a still image, and one frame or more can be displayed. The required information can be arbitrarily selected and recorded from the captured still image, and the location of the writing memory and the position of the output sub-screen can be arbitrarily changed.
