Abstract

PURPOSE:To prevent the time display from disturbing the confirmation of a subject by making a design of the time information shown in an electronic virewfinder(EVF). CONSTITUTION:A camera main body is provided with an EVF unit, etc., and the information shown on a monitor screen in a design instead of the numeric characters. That is, one hour is divided into four sections, 11:50-12:10, 12:05-12:20, 12:20-12:40 and 12:40-12:50. Then each of these time sections is representatively shown in the form of a design. This clock display is defined at the lower right part of a monitor screen as shown in Fig. (B), for example, and consists of a bit pattern shown in Fig. (C), for example, where the '1' parts form a character part. This clock display is carried out by a system control circuit which functions as a time information processing means.

2. Description of the Related Art Conventionally, an electronic view for confirming a subject
In the viewfinder, in addition to the current mode display, the tape remaining amount, the current time display, etc. are provided for the convenience of the photographer. Among them, the time display is made by characters such as numbers as shown in FIG.

[0003]

However, the display of the time information in characters may occupy more space than necessary in the electronic viewfinder, which hinders the confirmation of the subject. In addition, the time is set by the photographer because it is recorded together with the subject image, and accurate display such as what hour, minute, and second is not necessarily required. Furthermore, some photographers do not like the digital display of time numbers or the like.

The present invention has been made in view of the above circumstances, and a time display function capable of improving the operability during shooting without hindering the confirmation of the subject during shooting. It is an object of the present invention to provide a camera-integrated image recording device having a camera.

[0005]

In order to achieve the above object, a camera-integrated image recording apparatus having a time display function of the present invention is an electronic viewfinder for displaying a subject on a monitor and an electronic viewfinder for designating time information. It comprises a time information processing means for performing processing for display in the viewfinder.

[0006]

According to the camera-integrated image recording apparatus having the time display function of the invention, the time information processed by the time information processing means and displayed as a pattern is displayed in the electronic viewfinder.

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a configuration block diagram showing an embodiment of a camera-integrated image recording apparatus according to the present invention. At the time of recording, the video signal input from the input terminal 6 is subjected to predetermined processing by a known circuit such as the video signal input circuit 5 and the recording signal processing circuit 4, and the magnetic signal is transmitted via the terminal 3a of the switch 3 and the magnetic head 2. It is recorded on tape 1.

At the time of reproduction, the reproduction signal read from the magnetic tape 1 through the magnetic head 2 passes through the terminal 3b of the switch 3 and the reproduction signal processing circuit 7 and the reproduction signal detection circuit 1
Sent to 1. The reproduction signal subjected to the predetermined reproduction processing in the reproduction signal processing circuit 7 is mixed with the character signal generated from the character signal generation circuit 12 in the mixing circuit 8 and output to the output terminal 10 via the video signal output circuit 9. It is transmitted as a video signal.

The reproduction signal detection circuit 11 outputs a signal for discriminating the recorded portion and the unrecorded portion of the video signal, and sends the detection signal to the system control circuit 13. The operation unit 18 is used to instruct various operations such as reproduction, fast-forward, and rewind by operation, and sends an operation signal to the system control circuit 13. The system control circuit 13 is supplied with power from a battery 22 via a power supply voltage interface circuit 21, a backup power supply 20 for operating an internal clock, and a bar code input. Various instruction data is supplied from the interface circuit 19.

Each display of 10) is performed.

FIG. 5 shows an example in which the above character display is shown as a bit image pattern. The display pattern as shown in FIG. 5 is written as a bit image pattern, for example, in the RAM area of the character signal generating circuit 12 of FIG. 1 by a signal from a microcomputer (system control circuit 13) at the time of initial setting, When writing the mask ROM pattern on the character generator element, a certain character is set to the desired pattern as described above.

Next, FIG. 6 shows a display example of a timepiece character according to the embodiment of the present invention. Here, instead of the numerical display of the time in FIG. 4, the time information is displayed as a design.
That is, as shown in FIG. 7A, when displaying the time display pattern, for example, one hour is divided into four, and 11:50 to 1
2:10, 12: 05-12: 20, 12: 20-1
Each time of 2:40 and 12:40 to 12:50 is designed as a representative display by designing it. Similarly, other time zones are also displayed by the representative pattern. The clock display is displayed in the lower right part of the monitor screen, for example, as shown in FIG. The display as described above can be configured and displayed by a bit pattern as shown in FIG. 7C, for example, and the "1" portion constitutes the character portion in the figure.

The clock display processing is processed by the system control circuit 13 which is time information processing means.
The processing procedure will be described with reference to the flowchart of FIG. 7. First, in the OSD display, the clock RAM data is taken out (step S231), and the current clock (time) is set to, for example, FIG. 6A. It is determined which pattern of the characters belongs to (step S232), the character pattern is displayed (step S233), and the clock is displayed (step S23).
4) Return to main routine. Here, writing to the element of the character pattern is performed in the system initial setting before the main routine.

As described above, in the camera-integrated image recording apparatus having the clock display function according to the present embodiment, the time information is stylized and displayed in the lower right part of the EVF, which hinders the confirmation of the subject. Moreover, since the photographer can know the approximate photographing time, no particular problem occurs in photographing.

[0019]

According to the present invention, the time information is designed and displayed in the EVF, so that the space for display can be reduced and the time display hinders the confirmation of the object. This can be prevented. Therefore, it is possible to improve the operation even when the time is displayed.
