Abstract

PURPOSE:To allow a photographing person to recognize the timing of a picture recording start before the picture recording start by displaying a time up to the picture recording start during the waiting of the picture recording at the time of interval picture recording and self-timer picture recording. CONSTITUTION:When an interval picture recording button is depressed, the depression is transmitted through an operation input part 18 to a control circuit 17, and a picture recording/reproducing part 12 alternately repeats the waiting and the picture recording operation by the control signal of the control circuit 17. When a self-timer picture recording button is depressed, for example, after waiting for ten seconds, the picture recording is started, and during the five seconds before the picture recording start, the time up to the picture recording start is displayed at every second. Thus during the waiting of the self-timer picture recording and the interval picture recording, a display means 2 displays the constant information before a constant period. Thus the photographing person can surely recognize the timing of the picture recording start.

During recording, L E D (31 is stippled and E V
“Interval recording” is displayed in F (2).

The photographer should use the EVF (2) display or l-, I-raD (
3) It is determined whether the VTR is in recording standby or recording by looking at the state.

[Problems to be Solved by the Invention] Since the conventional V]'R is configured as described above, in self-timer recording or interval recording, the photographer can set the timing to start recording on the side where recording is to be started. It could not be predicted accurately, and there was a risk of missing the delicate timing to start recording.

In other words, when setting shooting conditions, interval recording
For example, every minute, self-timer recording, etc.
Although settings such as starting after 0 seconds are made,
It is difficult for the photographer to accurately grasp the passage of the set time during the shooting process.

This invention was made in order to solve the above-mentioned problems, and the objective is to provide an imaging device that allows the photographer to reliably recognize the timing of starting recording in self-timer recording and interval recording. do.

[Means for Solving the Problems] An imaging device according to the present invention is configured to cause a display unit to perform a certain display from a certain time 01) at the start of recording during the standby period of self-timer recording and interval recording. .

In response to control from a control circuit described later, characters corresponding to a predetermined display are generated as a video signal, and are displayed in seconds for a certain period of time from 1) 1j to the start of recording. It is generated by visualizing numbers.

(14) is an adder that adds the video double image from the recording/playback unit (I2) and the video signal from the character generator (13), and the video signal from this adder (14) is converted into video. It is displayed on the screen of the IEV F f2) as a display means. (16) is a video signal output terminal for outputting the video signal from the adder (14) to an external device such as Senjiba or V1'R, and (17) is for controlling the display by E V F (2), etc. , a control circuit that controls the operation of the VTR. Reference numeral (18) denotes an operation section that accepts and receives human input from operation buttons such as the self-timer recording button (4) and the interval recording button (5) shown in FIG. 5, and transmits it to the control circuit (18).

Next, the operation will be explained.

During recording, standby and stop recording, the signal captured by the camera unit (b) and converted into a video signal and the video signal generated by the character generator (13) are combined into an adder (
14), and is converted into a video image in EVF (21) and displayed on the screen in the EVF.A monitor (not shown) is also connected to the video signal output terminal (16). In this case, an image similar to the screen in EV F [2) is displayed on the monitor screen.

First, regarding interval recording, see Figure 2 (Al-(D
) will be explained with reference to the timing chart. Here, 2 seconds of recording and 58 seconds of recording standby are repeated alternately, and in the 5 seconds before the start of recording, the time until the start of recording is set by 1 second at the car position r5'', r4'', r3. , rl" and "1". 9. Click the interval recording button (
When 5) is pressed, this is transmitted to the control circuit (17) via the operator power unit (18), and interval recording is started. After 58 seconds, the camera part (1)
) is framed for 2 seconds, and this operation is repeated alternately (Fig. 2 (A)).

The character generator (13) is the control circuit (17)
During 2 seconds of recording, the text ``Interval Recording'' is generated as a video signal by the control signal from , and during 58 seconds of standby, the text ``Interval Recording Standby'' is generated as a video signal, and a signal indicating the start of recording is generated. r6 5 seconds ago.”
, 4 seconds ago r4'', ..., 1 second ago ``1'' are generated as video signals, and these numbers are erased at the same time as recording starts (Fig. 2 (B), FC)') . The screen display in IE V F (2) at this time is shown in Figure 3 (A
). FIG. 3(A) shows a display of a 3-second song at the start of recording during recording standby. The display at the bottom right corner of Figure 3 fA) changes from "5" to "5" every second from 5 seconds before the start of recording.
The number changes as follows: 4" → "3" → "2] → "1" → "." FIG. 3(B) shows the display during recording. At this time, if Senjiya is connected to the video signal output terminal (I6), an image similar to that shown in FIG. 3<Al, (B) will be displayed on the monitor screen.

L, E l) +3) is turned on during 2 seconds of recording by a control signal from the control circuit (17), and blinks at regular intervals during 58 seconds of standby (FIG. 2(D)).

Next, regarding self-timer recording, see Figure 4 (A1-(D)
This will be explained with reference to l. Here, when the self-timer recording button (4) is pressed, recording starts after 10 seconds, and in the 5 seconds before the start of recording, the time until the start of recording is set to r5. , r4. , r3. .

``rl'', ``rl,'' and so on. When the self-timer recording button (4) is pressed, this is transmitted to the control circuit (17) via the operation input section (18),
The recording and reproducing section (12) records the video signal from the camera section (1) after a period of 10 seconds according to the control signal from the control circuit (I7) (FIG. 4 (Δ)). The character generator (13) converts the text "Self-timer recording" into a video signal and generates the text "Self-timer recording standby J" during recording according to the control signal from the control circuit (17), and generates the text "Self-timer recording standby J" during 10 seconds of standby. At the same time as the video signal is generated, r5J is set at 5 seconds + ii + before the start of recording, "4" is set at 4 seconds before the start of recording,
..., the number ``1'' is issued as a video signal for each second of music, and this number is erased at the same time as recording starts (Figure 4 (B)
) iC) ) At this time, the screen in E V F (2) and the display on the right side of the monitor screen will change from "5" to "4" to "3" to r2 every second from 5 seconds before the start of recording. →「l」
→[] and so on. L l? , I) (
3) is off during the stop period before the self-timer recording button (4) is pressed by the control signal from the control circuit (17), and remains off for 10 seconds after the self-timer recording button (4) is pressed.
It blinks at regular intervals during the second standby period, and turns on when recording starts (FIG. 4(D)).

In this way, during the recording standby period for interval recording and self-timer recording, the number is displayed from 5 seconds before the start of recording, so there is no risk of the photographer missing the timing to start recording by visually checking this display. It will be resolved.

In the above embodiment, in interval recording and self-timer recording, the time from 5 seconds before the start of recording to the start of recording is displayed in numbers on the screen and monitor screen in 1 second position. As explained above, the timing to start the display can be set earlier or later than 5 seconds before the start of recording, and the time display until the start of recording can be set in a time unit different from the 1 second position. Good too.

Furthermore, the time until the start of recording may be displayed not in numbers but in analog quantities such as circular or bar-shaped figures, or it may be displayed on a liquid crystal display attached to the side of the VTR. good.

〔Effect of the invention〕

As described above, according to the present invention, the time until the start of recording is displayed on the EVF or the like during recording standby in interval recording and self-timer recording, so that the photographer can check the timing of the start of recording before the start of recording. There are effects that can be recognized in advance.
