JPH0789191B2 - Camera multifunction display - Google Patents

Description

The present invention relates to a multi-function display device for displaying time, date, etc., and more particularly to a multi-function display device mounted on a camera or the like.

[Prior Art] Generally, in a display device of a camera, the number of films,
It is considered to display a lot of information such as F value and shutter speed (TV). In particular, in a display device of an electronic still camera, in addition to the above-mentioned information, time, date,
More displays such as white balance and other items (ID) that display numbers are required. Items that do not always need to be displayed here, such as time, date, ID, TV,
The display segment is also considered to be used in combination. For example, by using a liquid crystal display device having a plurality of segments as shown in FIG. 3, time (hour, minute, second) as shown in FIG.
Display, date (month, day, year) display as shown in FIG. 5, 6
The ID shown in the figure and the TV shown in FIG. 7 can be displayed.

However, in such a conventional display device, a 4-digit left segment of 7 segments is used for ID and TV. Had to be evenly spaced, which could lead to the misreading of other displays. Therefore, for the time, a colon is displayed between the hour and minute, but
In the case of the date shown in the figure, for example, January 23, 1986 is changed to 86
There was a problem that it was mistaken for December 3.

[Problems to be Solved by the Invention] Therefore, an object of the present invention is to solve such a problem and to provide a multifunction display device of a camera in which display information is easy to see.

[Means for Solving the Problems] In order to achieve such an object, the present invention displays on the left side in a multifunction display device of a camera that displays a plurality of types of information including month information and date information. The means for determining whether the number of digits of information is 1 digit or 2 digits, the means for determining whether the number of digits of information displayed on the right side is 1 digit or 2 digits, and the right side by the determining means When it is determined that the number of digits of the information to be displayed in 1 is 1, the means for displaying the information to be displayed on the left side without changing the digit position and the number of digits of the information to be displayed on the right side by the determining means are 2 digits. When it is determined that the information is a digit, if the information displayed on the left side is one digit, the information displayed on the left side of one digit is displayed at the upper digit position, and if the information displayed on the left side is two digits, then two digits are displayed.
And a means for displaying the information displayed on the left side of the digit without changing the digit position.

[Operation] According to the present invention, the display position is set depending on the number of months and the number of days of the date being one digit, the number of days of the date being one digit and the number of days being two digits, and the other cases. It can be configured.

[Examples] Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a configuration of an embodiment of the present invention.

Reference numeral 1 denotes an arithmetic processing unit (CPU) for executing the control procedure shown in FIG. 2 (A), and also a photographing speed selection switch 11, a white balance selection switch 12, an exposure selection switch 13, and time, date, the number of shots, etc. ID switch 14 to set
The various information set by is displayed on the LCD display 5.

1A is a crystal oscillator that sends a clock signal to CPU1, and 1B is a crystal oscillator.
It is the power supply for CPU1.

2 is a read-only memory (ROM) for storing the control procedure shown in FIG. 2 (A), and 3 is a variable used for the control procedure shown in FIG. 2 (A). Random access memory (RAM).

Reference numeral 4 is an LCD driver for converting display information sent from the CPU 1 into a drive signal for the LCD display 5, and reference numeral 5 is an LCD display for performing display based on the drive signal from the LCD driver 4.

Reference numeral 6 is a main CPU that controls the photographing speed setting mechanism 7, the white balance setting mechanism 8 and the exposure compensation mechanism 9 according to the setting mode set by the selection switches 11 to 13, respectively.
Is. Reference numeral 15 is a setting switch for changing the setting conditions of the mode selected by the selection switches 11 to 14 in ascending order, and 16 is a setting switch for changing the setting conditions of the mode in descending order.

FIG. 2 (A) shows an example of the control procedure in the embodiment of the present invention.

In FIG. 2 (A), when the date display mode is set by the selection switch 14, the CPU 1 reads the date information, that is, the year, month, and day information from the RAM 3, and in step S1,
The year is displayed in the display areas 5 and 6 as shown in FIG.

In step S2, it is determined whether the read month information is a single digit, and if not, the process proceeds to step S6. Read month is 1
If it is a digit, it is determined in step S3 whether or not the number of digits of the date information read is one digit line.

When the number of digits of the day information is one digit, the month information is displayed in the display area 2 of the display 5 and the day information is displayed in the display area 4 as shown in FIG. 2 (C) (step S4). If the date information is not one digit, the month information is displayed in the display area 1 and the day information is displayed in the display areas 3 and 4 as shown in FIG. 2 (B) (step S5).

In step S6, it is determined whether or not the read date information has one digit. If the date information has one digit, the month information is displayed in the display areas 1 and 2, and the day information is displayed in the display area 4 (step S7).

When the date information is not one digit, the month information is displayed in the display areas 1 and 2 and the day information is displayed in the display areas 3 and 4 (step S8).

Hereinafter, every time the year, month, and day are displayed, this control procedure is performed, so that the easy-to-read date display can be performed.

FIG. 2D shows the second control procedure in the embodiment of the present invention.

In FIG. 2 (D), when the date display mode is set by the selection switch 14, the CPU 1 reads the date information, that is, the year, month, and day information from the RAM 3, and in step S1,
The year is displayed in the display areas 5 and 6 as shown in FIG.

In step S2, it is determined whether the read date information is a single digit, and if not, the process proceeds to step S6. The date read is 1
If it is a digit, it is determined in step S3 whether or not the number of digits of the month information read is one digit line.

When the number of digits of the day information is one digit, the day information is displayed in the display area 2 of the display 5 and the month information is displayed in the display area 4 as shown in FIG. 2 (F) (step S4). If the month information is not one digit, the date information is displayed in the display area 1, as shown in FIG.
Display month information in display areas 3 and 4 (step S
Five).

In step S6, it is determined whether or not the read month information has one digit. If the month information has one digit, the day information is displayed in the display areas 1 and 2, and the month information is displayed in the display area 4 (step S7).

When the month information is not one digit, the day information is displayed in the display areas 1 and 2 and the month information is displayed in the display areas 3 and 4 (step S8).

Hereinafter, every time the year, month, and day are displayed, this control procedure is performed, so that the easy-to-read date display can be performed.

[Effects of the Invention] According to the present invention, the display position of a display that is easily misidentified can be changed, so that it is possible to obtain an effect that the display is easy to see in a limited display space like a camera.
