Field of the Invention The present invention, in addition to operation members necessary for the original operation of the equipment such as a camera compatible with a new photographic system (hereinafter referred to as Advanced Photo System, hereinafter referred to as APS), a digital camera, a video camera, and the like. The present invention relates to a device having a data input operation member and a liquid crystal display device.

[0002]

2. Description of the Related Art As a first conventional example, FIG. 14 shows the structure of the rear surface of a general camera. Conventionally, on the back surface 101 of the camera 100, a viewfinder eyepiece 102, a zoom switch 103 for changing the focal length of the lens, a light emitting display element 105, a liquid crystal display device for displaying the date and various shooting data. 200 etc. are provided. A shutter release button 104 is provided on the top surface of the camera 100.

The light emitting display element 105 is, for example, a plurality of light emitting diodes having different light emitting colors, and is used to change the light emitting color or change the blinking period so that the user looks into the viewfinder eyepiece 102. , Notify the subject that the lens is in focus and that the flash firing capacitor has been charged.

The liquid crystal display device 200 includes a display unit 201 such as a liquid crystal display element, a plurality of display switches 202 for switching the display of the display unit 201, a plurality of mode switches 203 for switching the operation mode of the camera, and a circuit (not shown). It is composed of a substrate and the like, and is unitized.

FIG. 15 shows details of the surface portion of the liquid crystal display device 200. It shows a state in which all displayable characters, figures, symbols and the like of the display unit 201 are displayed. The display switch 202 is arranged on the left side of the display unit 201. In the vicinity of each display switch 202, “SEL” and “TITL” for displaying the function of each display switch 202, respectively.
Character strings such as "E", "ADJ", and "DATE" are described. The mode switches 203 are arranged on the upper portion of the display unit 201, and each mode switch 203 has a character string or a graphic 204 representing the function of the mode switch. Further, a triangular mark 205 for displaying the selected function is arranged in a portion of the display unit 201 facing each mode switch 203. A segment 206 for displaying relatively simple characters such as date, time, and katakana is arranged in the center of the display unit 201.
Below the display unit 201, in addition to the operation mode display 207 of the camera such as flash use, remote control use, self-timer use, etc., a warning display 208 such as insufficient battery capacity or no film loaded is graphically displayed. It is arranged.

As a second conventional example, for example, Japanese Unexamined Patent Publication No. 7-219013 discloses a camera using a liquid crystal display device that uses both a dot matrix display section and a segment display section. (Not shown). Characters such as "S" indicating the shutter priority mode, "A" indicating the aperture priority mode, and "M" indicating the manual mode are displayed on the dot matrix display portion.

[0007]

In the first conventional example described above, the display using the light emitting element 105 is used in the camera 100.
The user must remember the relationship between the display pattern and the display content that is preset by the user. Therefore, if there are many display patterns, it becomes difficult for the user to understand and remember everything. Furthermore, as the number of display patterns increases, each display pattern approximates each other, making it difficult for the user to determine what is being displayed.

On the other hand, in the display by the liquid crystal display device 200, since the operation mode display 207 and the warning display 208 are arranged in a graphic form, they are easier to understand than the display by the light emitting element 105 and are slightly improved. However, when the amount of information to be displayed increases, the liquid crystal display device 20
0 display section 201 is enlarged or individual display 2
07, 208, etc. must be reduced. Display unit 2
When 01 is increased, it is disadvantageous in terms of cost and reduction in size and weight of the camera, and when each display is reduced, visibility is extremely deteriorated. In particular, like a camera, many members (shutter release button, button / dial for changing / entering exposure factor, members for film feeding, viewfinder, etc.) for achieving the original function (imaging) are arranged. Then, it is virtually impossible to enlarge the display unit. In addition, although the operation mode and the content of the warning are graphically represented, it is not always easy for the user to understand.For example, whether the operation mode display such as flash emission or the warning display such as battery replacement is displayed by the user beforehand. It must be understood and remembered. further,
In the case of warning display, it is virtually impossible to display the solution graphically.

In the second conventional example, since characters or the like indicating the currently set camera control mode or the like are displayed on the dot matrix display section of the liquid crystal display device, a specific operation mode or warning is displayed. The display size of the dot matrix display unit can be increased without allocating the space of the display unit to the figure, the symbol, etc., and the visibility of the display device is improved. However, as in the first conventional example, the user must remember the relationship between the display characters and the display contents that are preset on the camera side, and determine whether the operation mode display or the warning display is displayed. It is difficult.

The present invention has been made in order to solve the above-mentioned problems of the conventional example, and provides an electronic device with a display function capable of easily displaying an operation mode, a warning and the like of an electronic device such as a camera. It is intended to be provided.

[0011]

In order to achieve the above object, the first display-equipped device of the present invention includes a dot matrix display section composed of a full-screen dot matrix and is selected from characters, figures and symbols. Display means capable of displaying at least one kind, and characters displayed on the display means,
Display control means for controlling at least one of the size and the position of the figure or the symbol to be changeable.

As the display means, for example, a liquid crystal display element or the like formed of a dot matrix on the entire surface is used. The display control means uses a microcomputer including, for example, a CPU and a memory. By executing a predetermined program by the display means and controlling ON / OFF of each dot matrix, predetermined characters, figures and symbols are displayed on the dot matrix display section. Compared with the conventional example using the segment display, a predetermined character or the like can be displayed by using the entire displayable area of the display means (liquid crystal display element), for example, a character string for displaying the date, the content of the operation mode, or the like. , Graphics, symbols, etc. are displayed in an optimal size and position.

In the above structure, the display control means is provided with operation control means for executing a plurality of different operation modes and operation mode selection means for selecting one operation mode from the plurality of operation modes. The operation mode selected by the operation mode selection means is displayed on the dot matrix display unit by at least one method selected from character display, graphic display and symbol display, and after the operation mode selection is confirmed, the size of the selected display is displayed. It can be configured to change at least one of the height and the position.

As the operation control means, for example, the same microcomputer as the display control means is used. A switch arranged on the operation surface of the device is used as the operation mode selection means when the user selects the operation mode. For example, when the user arbitrarily selects from a plurality of operation modes such as setting the date and time, switching the date or time display, using or canceling the flash in the case of a camera, etc., the display control means should be in the normal state. A character string (for example, "flash") that erases the display of the date, time, and the like displayed in, and displays the operation mode (for example, use of flash) selected by the operation mode selection unit using the entire displayable area of the display unit. )) And a graphic symbolizing the operation mode (for example, a lightning bolt) are displayed, so that it is easy to confirm the selected operation mode. Further, after completing the selection of the operation mode, for example, the character strings and the like displayed when the operation mode is selected are erased, the date and the like are displayed again, and the display position of the figure or the like symbolizing the operation mode is changed. The display of the display means in the normal display state is clear and simple.

On the other hand, when the device automatically selects the operation mode, such as a predetermined warning, the microcomputer, the sensor and the like function as the operation mode selection means. For example, in the case of a warning mode such as battery remaining capacity reduction,
The dot matrix display section displays a character string such as "DENT KOKUKA" and blinks a figure representing the shape of the battery. This allows the user to understand the content of the warning and the solution.

Further, in the above-mentioned structure, at least one of the operation modes requires input of character data within a predetermined number n of characters, and the data input means capable of inputting character data one character at a time includes the input of character data. When the required operation mode is selected, the display control means is the i-th (i
= 1 to n-1) is displayed in the first area of the display means in the first size, and when the (i + 1) th character data is input, the i-th character input previously is displayed. The data may be configured to be moved to the second area of the display means and displayed in a second size that is smaller than the first size.

For example, in the data input mode, since the displayable area of the display means (liquid crystal display element) is limited,
When the character display is enlarged, the number of characters that can be displayed is limited.
On the contrary, when the number of displayed characters is increased, the size of the characters is limited. Therefore, only one character currently being input is enlarged to the first size and displayed in the first area, and the already entered character string is displayed in the second area with a second size smaller than the first size. By reducing the size of the display, the number of characters that can be displayed is not reduced, and the characters can be easily confirmed.

A second device with a display function of the present invention is a dot matrix display section which is composed of an entire surface dot matrix and is capable of displaying at least one kind selected from characters, figures and symbols, and predetermined characters and figures. And at least one of a display unit including a segment display unit formed to display at least one selected from symbols and symbols, and at least one of the size and position of a character, figure, or symbol displayed on the dot matrix display unit. Display control means for controlling. That is, a segment display unit is added to the configuration of the device with the first display function. For example, by displaying a relatively easy-to-understand graphic such as a lightning bolt symbolizing the use of a flash with a segment, display control by a display control means (microcomputer or the like) becomes easy.

In the above-mentioned structure, the display control means includes an operation control means for executing a plurality of different operation modes and an operation mode selection means for selecting one operation mode from the plurality of operation modes. The contents of the operation mode selected by the operation mode selection means are displayed on the dot matrix display section by at least one method selected from character display, graphic display and symbol display, and the operation mode selection is confirmed and then selected on the segment display section. It is possible to display a character, a graphic or a symbol indicating the selected operation mode and change the display state of the dot matrix display section. That is, after the operation mode selection is completed, the display by the dot matrix display unit can be turned off, and the power consumption is reduced.

Further, in the above construction, at least one of the operation modes requires the input of character data within the predetermined number n of characters, and the data input means capable of inputting the character data one character at a time is included, and the character data is input. When the required operation mode is selected, the display control means is the i-th (i
= 1 to n-1) is displayed in the first area of the dot matrix display unit in the first size, and the i + 1th character data is input, the i-th input character The character data can be moved to the second area of the dot matrix display unit and displayed in a second size smaller than the first size. That is, as in the case of the device with the first display function described above, it is easy to check both the character being input and the character string that has already been input while making the most effective use of the displayable area of the display means.

A third device with a display function according to the present invention includes a dot matrix display section composed of a dot matrix on the entire surface, and is capable of displaying at least one kind selected from characters, figures and symbols. At least a portion of the matrix display portion, display means capable of displaying in a color different from the display color of the other portion, and the size of the characters, figures or symbols displayed on the dot matrix display portion,

That is, a partial display color changing function in the dot matrix display section is added to the configuration of the device with the first display function. By displaying the display colors partially different from each other, it is possible to make the display content of the portion particularly conspicuous.

In the above structure, the display control means includes operation control means for executing a plurality of different operation modes and operation mode selection means for selecting one operation mode from the plurality of operation modes. The contents of the operation mode selected by the operation mode selection means are displayed on the dot matrix display section by at least one method selected from character display, graphic display and symbol display, and after the operation mode selection is confirmed, the selected display is displayed. It can be configured to change at least one of size, position and display color. For example, when an operation mode is selected, a graphic symbolizing the selected operation mode is displayed in a display color different from the normal display, and after the operation mode selection is completed, the normal display color is displayed. With such a configuration, the confirmation of the selection of the operation mode /
It becomes easy to make undetermined decisions.

Further, in the above construction, at least one of the operation modes requires input of character data within the predetermined number n of characters, and the data input means capable of inputting character data one character at a time is included, and the input of character data is performed. When the required operation mode is selected, the display control means is the i-th (i
= 1 to n-1) is displayed in the first area of the display means in the first size and / or the first display color, and the i + th
When the first character data is input, the previously input i-th character data is moved to the second area of the display means,

And a display control means for controlling so that it can be changed. That is, in addition to the configuration of the device with the second display function, a partial display color changing function in the dot matrix display unit and the segment display unit is added, or to the configuration of the device with the third display function,
A segment display unit whose display color can be changed is added. For example, a relatively easy-to-understand figure such as a lightning bolt symbolizing the use of a flash is displayed as a segment and displayed in a display color suitable for each display content to make the display content particularly noticeable. It is possible.

In the above structure, the display control means is provided with operation control means for executing a plurality of different operation modes and operation mode selection means for selecting one operation mode from the plurality of operation modes. The contents of the operation mode selected by the operation mode selection means are displayed on the dot matrix display section by at least one method selected from character display, graphic display and symbol display, and the operation mode selection is confirmed and then selected on the segment display section. It is possible to display a character, a figure, or a symbol indicating the selected operation mode in a predetermined display color and change the display state of the dot matrix display section. With such a configuration, for example, when an operation mode is selected, a graphic symbolizing the selected operation mode is displayed on the dot matrix display section in a display color different from the normal display, and after the operation mode selection is completed, the dot matrix display section is displayed. Can be erased, power consumption can be reduced, and it becomes easy to determine whether the operation mode is selected or not.

Further, in the above construction, at least one of the operation modes requires input of character data within a predetermined number n of characters, and the data input means capable of inputting character data one character at a time includes the input of character data. When the required operation mode is selected, the display control means is the i-th (i
= 1 to n-1) is displayed in the first area of the display means in the first size and / or the first display color, and the i + th
When the first character data is input, the previously input i-th character data is moved to the second area of the display means,
A second size less than the first size and / or a first size
The second display color different from the display color of can be configured. That is, by adding a change in the display color to the configuration of the device with the second display function, both the character being input and the character string that has already been input due to the size of the character and / or the difference in the display color. It becomes easy to confirm.

Further, in each of the above-mentioned configurations, the display control means may be configured to display in a display color different from the normal display color when the content displayed on the display section is related to a predetermined warning. it can. That is, for example, by setting a display color related to a warning such as a low battery remaining capacity to a display color (red / transparent) different from a normal display color (for example, black / transparent), it is possible to confirm that the display is related to the warning. Easy to recognize.

In the above structure, the display means includes a liquid crystal display element and a lighting device, and the lighting device is configured to illuminate a predetermined area of the liquid crystal display element with light of a color different from that of the other areas. be able to.

Next, an example of the photographing operation of the camera 100 will be described with reference to the flowcharts shown in FIGS. It should be noted that it is assumed that a film has already been loaded in the camera 100, and a description of the film loading operation will be omitted.

First, when a power switch (not shown) of the camera 100 is turned on (# 1), the CPU 300 resets the setting state of the camera 100 (# 3), and the CPU 300
Determines whether or not the lid 121 of the switch panel 120 is opened by turning on / off the switch 140 (#
5).

When the cover 121 of the switch panel 120 is closed, the CPU 300 performs a normal photographing operation.
In the case of a normal shooting operation, the CPU 300 displays the date 131 and the title 1 that has already been input, as shown in FIG.
32 and the like are displayed on the liquid crystal display element 130 (# 7). Next, the built-in timer is once reset and started (# 9).

Further, the CPU 300 determines whether or not the switch S1 (not shown) which is turned on when the shutter release button 104 is in the so-called half-pressed state is turned on (# 11). When the switch S1 is turned on,
The CPU 300 operates the distance measuring circuit 304 (# 13),
It is detected whether or not the lens is in focus on the subject (# 15). When the lens is not in focus on the subject, the CPU 300 drives the lens driving motor M1 via the drive circuit 306 to perform a focusing operation (for example, movement of the focal position of the lens from infinity to the closest distance side). Do (#
17). The signal from the distance measuring circuit 304 changes as the lens moves. When the CPU 300 detects that the lens is focused on the subject based on the signal from the distance measuring circuit 304, the CPU 300 stops driving the lens driving motor M1 via the driving circuit 306.

In parallel with the focusing operation, the photometric circuit 305
The brightness of the subject is measured (# 19). CPU 300 is
Based on the signal from the photometric circuit 305, the aperture value and shutter speed of the lens are determined according to a preset program (# 21). Here, the CPU 30
A value of 0 determines whether or not the determined shutter speed is slower than a hand-shake limit speed preset according to the focal length of the lens or the like (# 23). When the shutter speed is slower than the camera shake limit speed, the CPU 300
Select flash emission (# 25). Then, the aperture value and the shutter speed of the lens are changed according to the guide number (emission amount) of the flash (# 27). further,
The CPU 300 displays shooting conditions such as focus display, lens aperture value, shutter speed, and flash display on the finder display element 308 and the liquid crystal display element 130 (# 2).
9).

Next, the CPU 300 determines whether or not the switch S2 (not shown) which is turned on when the shutter release button 104 is pushed further deeply (#).
31). When the switch S2 is turned on, the CPU 300 drives the shutter unit 307 at the determined predetermined shutter speed via the drive circuit 306, drives the flash light emission circuit 303 as necessary, and exposes the image of the subject on the film. (# 33).

When the exposure is completed, the CPU 300 drives the film feeding motor M2 via the drive circuit 306,
The film is wound up by one frame, and at the same time, the shutter unit 307 is charged (# 35). In parallel with the film winding operation, the CPU 300 causes the magnetic head 311 to display a title, a shooting date, and a camera orientation at the time of shooting in a magnetic information recording area provided above or below each frame on the back surface of the film. , Data such as screen size such as standard size or panorama size is recorded (# 37). When the film winding is completed, the finder display element 308
The display of the photographing conditions such as the focus display, the lens aperture value, the shutter speed, and the flash display is erased from the liquid crystal display element 130 and the normal display (# 39). Furthermore, C
The PU 300 determines whether or not the photographed frame is the last frame (# 41), and if it is the last frame, the film is rewound into the film cartridge (# 43). When the rewinding of the film is completed, the CPU 300 displays a graphic representing “no film” in the warning display area 135 of the liquid crystal display element 131 and controls the EL plate drive circuit 309 to turn the area 141 of the EL plate 140 red. It emits light (# 45).

When the switch S2 is not turned on in # 31, that is, when the shutter release button 104 is not pushed deeply and when it is not determined that it is the last frame in # 41, the CPU 300 prepares for the next photographing. , It is determined whether or not the switch S1 is turned on (# 11).

When the CPU 300 determines in step # 11 that the switch S1 is not turned on, the CPU 300 compares the count value of the timer with a predetermined value and determines whether or not a predetermined time has elapsed (# 47). When no operation is performed within a predetermined time after the power switch is turned on, or when the switch S1 is once turned on and there is no next on within a certain time, the CPU 300 turns off the power switch ( # 49), the date, time and the like are enlarged and displayed on the liquid crystal display element 130 (# 50).

The power switch (not shown) is a push switch that does not stop when the switch is pushed in and elastically recovers automatically. Once it is turned on, the power circuit 302 is turned on and then again. When turned on, the power supply circuit 302 is turned off.

At # 5, when the cover 121 of the switch panel 120 is open, the CPU 300 performs a data input operation. In the data input operation, the CPU 300 sets the liquid crystal display element 130 to the data input display state (# 10
1) On the display screen of the liquid crystal display element 130, the display of the titles and the like that have already been input is erased, and the newly input characters, numbers, symbols, etc. can be displayed (# 1
03). Further, since the number of characters that can be input is limited, the CPU 300 resets the character number counter (# 1
05), and waits for an input from the switch panel 120.

When a signal is input from the switch panel 120, the CPU 300 outputs the signal.
It is determined whether or not it is the first input signal from 20 (# 10
7). If it is the first input signal, the CPU 300 determines whether the input signal is a signal corresponding to backspace (or clear) (# 109). Backspace is meaningless when nothing is input, so CPU
300 ignores the input (# 111), resets the data number counter, and waits for the next input (# 113).

If the signal from the switch panel 120 is not a signal corresponding to backspace (or clear), then C
The PU 300 determines whether or not the signal from the switch panel 120 is a signal corresponding to cursor movement (# 11).
5). When nothing is input, the cursor movement is meaningless, and similarly, the CPU 300 ignores the input (# 111), resets the data number counter, and waits for the next input (# 113).

Further, when the signal from the switch panel 120 is not the signal corresponding to the movement of the cursor, the CPU 30
0 determines whether or not the signal from the switch panel 120 corresponds to the character type setting (selection of kana, alphabet, etc.) (# 117). If the signal from the switch panel 120 corresponds to the character type setting, the CPU 30
For 0, the character type is set according to the signal from the switch panel 120 (# 119), and then the signal input from the switch panel 120 is replaced with the signal according to the selected character type. For example, when kana is selected, the signal from the specific key switch 122 of the switch panel 120 is replaced with the signal corresponding to “A”. On the other hand, if the alphabet is selected, the same specific key switch 1
Replace the signal from 22 with "A". Then, the data counter is reset and waits for the next signal input from the next switch panel 120 (# 113).

Further, when the signal from the switch panel 120 is not the signal corresponding to the character type setting, the CPU 300
Determines whether the signal from the switch panel 120 corresponds to the confirmation (# 121). Switch panel 1
If the signal from 20 does not correspond to the confirmation, the signal from the switch panel 120 corresponds to normal characters, numbers, symbols, etc., so that the CPU 300 inputs the inputted characters or the like on the liquid crystal display element 130. Characters, numbers, symbols, etc. corresponding to the signal input to the character display area 134 are enlarged and displayed (# 123). Here, characters and the like are displayed on the liquid crystal display element 130 for the first time. And the CPU 300
Waits for the next signal input from the switch panel 120.

When the signal from the switch panel 120 is a signal corresponding to confirmation, when nothing is input,
Since the confirmation is meaningless, similarly, the CPU 300 ignores the input (# 111), resets the data number counter, and waits for the next input (# 113).

Next, if there is an input from the switch panel 120, it is not the first input in # 107, so C
The PU 300 moves the characters or the like displayed in the input character display area 134 of the liquid crystal display element 130 to, for example, the user name display area of the liquid crystal display element 130 and displays them in a normal size (# 125).

Next, the CPU 300 determines whether or not the newly input signal corresponds to the backspace (# 127). When the signal from the switch panel 120 is a signal corresponding to the backspace, the CPU 300 returns the cursor by one character in the character string 132a being input on the liquid crystal display element 130 shown in FIG. The character is erased (# 129). Further, the data number counter is decremented by 1 (# 131). Switch panel 1
If the signal from 20 corresponds to the clear signal, the CPU
The liquid crystal display device 300 erases all the character strings input so far on the liquid crystal display device 130 and returns the cursor to the initial position. It also resets the data number counter. Then, the CPU 300 waits for the next signal input from the switch panel 120.

If the signal from the switch panel 120 is not a signal corresponding to backspace (or clear), then C
The PU 300 determines whether or not the signal from the switch panel 120 is a signal corresponding to cursor movement (# 13).
3). When the signal from the switch panel 120 is a signal corresponding to the movement of the cursor, the CPU 300 moves the cursor on the liquid crystal display element 130 in the direction indicated by the signal from the switch panel 120 (# 135), and outputs the signal from the switch panel 120. Wait for the next signal input.

Further, when the signal from the switch panel 120 is not the signal corresponding to the movement of the cursor, the CPU 30
0 determines whether or not the signal from the switch panel 120 corresponds to the character type setting (# 137). When the signal from the switch panel 120 is a signal corresponding to the character type setting, the CPU 300 changes the character type according to the signal from the switch panel 120 (# 139), and subsequently changes the signal input from the switch panel 120. Replace with a signal according to the character type.

Further, when the signal from the switch panel 120 is not the signal corresponding to the character type setting, the CPU 300
Determines whether the signal from the switch panel 120 corresponds to the confirmation (# 141). Switch panel 1
If the signal from 20 is not the signal corresponding to the confirmation, CP
The U300 magnifies and displays the input characters and the like corresponding to the signal input to the input character display area 134 on the liquid crystal display element 130 (# 143), and the U300 displays the characters from the switch panel 120. Wait for the next signal input.

When the signal from the switch panel 120 is a signal corresponding to confirmation, the CPU 300 stores the data such as the character string input so far in the RAM or the like (# 14
5) Display the newly entered title, etc.
The display of the liquid crystal display element 130 is changed (# 147).

By closing the lid 121 of the switch panel 120, the data input state is completed and the normal photographing state (# 9) is restored. In addition, during the data input, the lid 121 of the switch panel 120 is not confirmed without confirming the input data.
When is closed, the CPU 300 cancels the data input so far and ends the data input.

Further, when the CPU 300 detects that the remaining capacity of the battery has dropped below a predetermined amount, for example, the warning display routine shown in FIG. 11 is interrupted regardless of which of the above steps is being executed. That is, when the remaining capacity of the battery decreases (# 201), the CPU 300 erases the display of the date 131 and the title 132 of the liquid crystal display element 130 (# 203), and as shown in FIG. 3 or 4, for example,
The character string "DENT RECALL" is displayed in the area where the date 131 and the like were displayed, and at the same time, a graphic representing the battery replacement request is displayed in the warning display area 135 (# 205). At the same time, the EL plate drive circuit 309 is controlled to cause the region 141 of the EL plate 140 to emit red light (# 207). further,
If the battery is low and cannot operate normally,
Lock the shutter release button 104 (# 20
9).

In the above embodiment, the liquid crystal display element 1
A transparent / black display such as a general nematic liquid crystal or a TN liquid crystal is used as 30, and an EL that emits two colors is used as illumination.
Although the plate 140 is used, the present invention is not limited to this configuration. For example, a transparent / black display liquid crystal display element and a transparent / red display guest host type liquid crystal display element are overlapped to form a normal date display or input data display. The driving of the liquid crystal display element may be switched between the above cases and the warning display. Furthermore, a guest / host type liquid crystal display element for transparent / green display and a guest / host type liquid crystal display element for transparent / reddish purple are overlapped, and both are simultaneously driven to obtain four colors of green, reddish purple, black and transparent. The display can be done.

Further, in the above-mentioned embodiment, the liquid crystal display element 130 having the entire surface formed of the dot matrix is used, but the display of the date 131, the warning display 135 and the like may be the segment display similar to the conventional one. .

In the above embodiment, the camera using a film having a magnetic recording area such as an APS compatible film is described, but the invention is not limited to this, and a camera using a conventional 135 type film is used. The present invention can be applied to any type of image pickup device as long as it has a display element such as a digital camera or a video camera. Furthermore, not limited to cameras,
A device having a display element such as a mobile phone may be used. In particular, in the case of a device that uses a color liquid crystal display device as a monitor, such as a digital camera or a video camera, a warning display in a noticeable color such as red and a method for solving the problem are displayed on the color liquid crystal display device with a monitor image. You may display it.
