Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital camera for electronically photographing a subject, and more particularly to a digital camera capable of displaying a large image.

[0002]

2. Description of the Related Art In recent years, among techniques taught as a display technique for digital cameras, for example, Japanese Patent Laid-Open No. 7-111607.
In the publication, there is proposed a rotary folding monitor mounting device which is mounted on the lower side of a camera-integrated VTR. By rotating backward on the lower side of the back side, the monitor section facing the back side faces upward, and in this state the VTR
You can hold the integrated camera body to take pictures.

Further, Japanese Patent Laid-Open No. 9-179119 discloses a backlight for a panel which has a transparent display panel and is constructed such that the first and second covers can be opened and closed by a fulcrum shaft. A system has been proposed. The first cover is provided with the liquid crystal, the diffusion plate and the light guide plate, and the second cover is provided with the reflection plate, so that the two covers can be opened and closed. This is a display system in which external light from the reflection plate can be used as a backlight when opened, and a light source from the side surface of the light guide plate can be used as a backlight when closed.

Such a conventional technique is a device for making the display screen easier to see, and can be used depending on whether the surroundings are bright or dark.

[0005]

However, in the display method taught by the above-mentioned Japanese Patent Laid-Open No. 7-111607,
When shooting in a place exposed to direct sunlight, the monitor on the back is simply rotated so that direct sunlight can be easily avoided, and it is possible to open the monitor on the back of the camera to display. After all, this is a device for attaching to the display part for awnings. Further, the internal structure of the display unit has not been sufficiently proposed, and it is presumed that a well-known technique is applied so that the direction of the display can be simply changed to prevent direct sunlight. Regarding the display on this display,
No consideration is given to active energy-saving (abbreviated as "energy-saving") measures.

On the other hand, in the display system taught by the above-mentioned Japanese Patent Laid-Open No. 9-179119, not only is the monitor unit opened, but
By switching between the backlight and reflector, it is bright and energy-saving. However, this method
Besides the liquid crystal for display, the diffusion plate, the light guide plate and the reflection plate are overlapped with each other, and when the two covers are folded, the entire thickness thereof becomes considerably large.

In this method, in particular, the light guide plate bends the optical path by 90 ° so that the light applied from the side surface is not necessarily high in light guide efficiency, and in order to maintain the backlight effect, the thickness of the light guide plate itself is small. For example, about 1 mm is required, and it cannot be made thinner than the predetermined size of the light emitting part or the like related thereto, and as long as it is necessary to efficiently apply light to the light guide plate through the reflection plate in operation, the entire device is There was a problem that the thickness became thicker.

The present invention has been made in view of such a situation as described above, and an object of the present invention is to perform a display operation for saving energy when the surroundings are bright in a digital camera having a large screen, and when the surroundings are dark. It is to provide a digital camera that enables bright display using a backlight.

[0009]

[Means for Solving the Problems] In order to solve the above problems and achieve the object, the present invention takes the following means. That is, according to the first aspect, a liquid crystal member for displaying an image, a display member formed of a diffusion plate in close contact with the liquid crystal member, and a first connection for connecting the display member to the back surface of the digital camera body of the present invention. A digital camera comprising: a member, a light source member (light emitting member) including a sheet-shaped light source, and a second connecting member that connects the light source member to the digital camera body along the display member. The first and second connecting members propose a digital camera that holds the display member and the light source member in a state of being in close contact with or apart from each other. The light source member is a backlight member, and the light source member is connected to the digital camera main body by a connecting member having two or more rotatable fulcrums, and can be closely attached to the front surface of the digital camera and the back surface of the display member. We propose the above described digital camera as a feature.

Further, the present invention is a digital camera having a display member composed of a liquid crystal member, a diffusion plate and a sheet-like light emitting member, and a connecting member for rotatably connecting the display member to the digital camera body. The digital camera described above is proposed, which can be opened and closed on the back surface of the digital camera. The above-mentioned digital camera is proposed in which the light source member is composed of a light emitting layer sandwiched between two sheets, and at least one sheet is made of a plate material having a diffusion function.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below with reference to a plurality of embodiments. 1A and 1B show a structural embodiment of a digital camera according to the present invention.
One is illustrated. First, FIG. 1A shows a conceptual configuration diagram as a first embodiment, and FIG. 1B described later in detail shows a conceptual configuration diagram as a second embodiment.

(First Embodiment) FIG. 1A and FIGS.
The digital camera of the first embodiment will be described based on FIG. The digital camera 100 illustrated in FIG. 1A is composed of the following components. That is, the digital camera 100 has a display member 60 including a liquid crystal member 3 for displaying an image and a diffusion plate 4 in close contact with the liquid crystal member 3.
A first connecting member 1 for connecting the display member 60 to the back surface of the digital camera body 50 so as to be openable and closable, a light emitting member (that is, a light source member) 5 including a sheet-like light source, The light emitting member 5 can be opened and closed, for example, outside along the display member 60.
It is mainly composed of a second connecting member 2 which is connected to 0.

The first connecting member 1 is rotatably connected to the connecting hole formed in the side surface of the digital camera body 50 by a rotating shaft. The second connecting member 2 has two fulcrums, and one of the fulcrums is pivotally supported by a connecting hole formed on the side surface of the digital camera body. And
When the display member 60 and the light emitting member 5 are opened, the first and second connecting members 1 and 2 bring the light emitting member 5 into close contact with the front surface of the camera body 50, or the display member 60.
Can be held in close contact with or separated from the back surface of the diffuser plate 4 that forms

When it is bright, the light emitting member 5 is separated from the display member 60, and ambient light (external light) incident from the rear side is used as a backlight, so that the light emitting member 5 does not need to emit light, and accordingly, "energy saving" can be achieved. "become. On the other hand, when it is dark, the light-emitting member 5 is brought into close contact with the display member 60 to emit light, so that bright display can be performed. Further, since the sheet-shaped light emitting member 5 is adopted here, the display unit is more than the conventional configuration using the light guide plate which irradiates the light from the side surface and reflects the light by about 90 ° as described in the description of the prior art. Can be made thinner (details will be described later).

2 to 7 show examples of use of the digital camera according to the first embodiment of the present invention in the appearance of the camera in each case. First, FIG. 2A is a perspective view showing an appearance of a digital camera at the time of shooting when the surroundings are dark. That is, the light source is turned on because it is used in the dark. Therefore, the display member 60 including the liquid crystal (LCD) 3 and the diffusion plate 4 which are axially supported by the first connecting member 1.
The light emitting member 5 including a sheet-like light source along the back side of the sheet.
The display member 60 with the axis of the second connecting member 2 as the center.
It is set in a position in close contact with the back surface of the, and light emission is driven by applying a required voltage.

As described above, even when the contents of the liquid crystal screen are difficult to see due to the dark surroundings, or even when the liquid crystal having low brightness is adopted, the artificial backlight effect is provided by the thin sheet-like light source. Bright display can be performed, and the displayed contents can be easily seen. At this time, both shaft ends of the first connecting member 1 are illustrated in FIGS. 2B and 2C so as to be maintained at a desired angle while being in close contact with the connecting portion 51 on the camera body side. It is formed in the shape as described above.

More specifically, a connecting portion 51 formed on the body side of the digital camera body 50 shown in an enlarged view in FIG. 2B.
The concave portion having a substantially triangular shape is concentrically formed around the center axis of the rotary shaft. Similarly, a shaft end portion of the first connecting member 1 in which the convex and concave portions are stepped by reversing the concave-convex relationship to a shape similar to this, is formed as shown in an enlarged view in FIG. 2C.

Such a connection relationship is displayed, for example, on the display unit 60.
When is rotated, it can be stopped and fixed periodically at a position where the concave portion and the convex portion fit together, and for example, a hinge or a mechanism with a claw such as a claw pressing fitting or a ratchet can be used instead. By this mechanism, the user can obtain a click feeling during the turning operation. In addition, this makes it possible to temporarily and reliably fix and maintain the desired opening degree (angle).

The connection including power supply between the LCD 3 and the digital camera main body 50 uses a well-known connection technique such as a flexible substrate or a lead wire passing through the shaft center of at least one connecting portion. Further, the predetermined circuit for display itself may be provided in the flexible substrate to reduce the number of lead wires.

FIG. 3 shows the appearance of the digital camera 100 when it is photographed in a bright case.

In the digital camera body 50 of this example, a power SW 11 is provided in the vicinity of the release SW 10, and an image rotation SW 12 and an image display mode SW are provided on the back surface.
13 and the TV recording / playback mode SW 14, a slide type zoom SW 15 and a slide type brightness setting volume 16 also used as a backlight SW are operably provided. In addition, a headphone jack hole 18 is provided near the optical finder 17 for observing the subject. Furthermore, memory card 3
0 can be inserted as a replaceable external storage medium.

In the case of this example, since the liquid crystal screen is clearly visible due to the bright surroundings, the sheet light source 5 is turned off. Then, the sheet-shaped light source 5 is rotated around the second support member 2 to a position opposite to the display member 60 as shown in the drawing. You can still shoot in this state, but if you just want to display the captured image by retracting the lens barrel without using it,
The magnet 20 provided on the front surface of the camera body 50 may be used in a state in which the metal portion of the frame body (not shown) of the sheet-shaped light source 5 is adsorbed and integrally fixed to the front surface. Although the magnet 20 is provided here as a temporary fixing and holding means, other well-known means may be adopted instead of the magnet.

Next, FIG. 4 illustrates a usage state of the digital camera 100 at the time of reproducing photographed image information and recorded TV image information. That is, as shown in the figure, the front portion of the digital camera 100 is set downward, and the display member 60 is set up. A predetermined memory card 30 is inserted into the digital camera body 50 in this state, for example, the TV recording / playback mode SW14 is pressed to switch to the playback mode of the TV recorded image, and the TV recording information is compressed as data compressed according to the specifications such as MPEG4. It can be read from the recorded memory card 30 and reproduced and displayed. The sound at this time can be heard through headphones (not shown) connected to the headphone jack hole 18.

Since it is bright, the sheet-shaped light source 5 for the backlight is folded back downward, and in this example, external light brings about a backlight effect from the rear side as shown by an arrow. By using it in this way, the display content becomes a slightly transparent and transparent display, and the quality is improved.

On the other hand, FIG. 5 shows a digital camera 1 in which the display contents are illuminated by the sheet light source 5 when the surroundings are dark.
00 shows the state of use. In this case, since the amount of external light is small, it is better to artificially supplement the backlight effect for better display content. Further, when the surroundings are dark, when the sheet-shaped light source 5 is set behind the display member (LCD 3) and then the power is turned on, the sheet-shaped light source 5 exerts a backlight effect and the liquid crystal display can be seen. It will be easier.

The liquid crystal of the LCD 3 which constitutes the display member 60 is made of a plastic or polymer material so that the contents can be displayed with the contrast as clear as possible. However, the above-mentioned backlight is necessary when no external light is obtained. In this example, the camera body 50 and the LCD 3 of the display member 60 are fixedly held by a combination of the magnet 21 and the magnet 22, so that they are surely attracted to each other.

Here, the structure and operating conditions of the sheet light source 5 will be described with reference to FIGS. 6 (a) to 6 (d). Figure 6
FIG. 6A shows a cross-sectional view of the structure having the sheet-shaped light source 5, and FIG. 6B shows a graph of the applied voltage supplied to the sheet-shaped light source 5.

In the layer structure of this cross section, a transparent sheet is provided as the uppermost layer, and electrodes for applying a pulsed voltage as shown in FIG. An inorganic EL (Electro Luminescence) light emitting layer as a light source is adopted below the metal layer, and a metal plate forming a part of the camera cover also serves as the GND electrode in the lowermost layer.
That is, the sheet-shaped light source 5 is an inorganic EL element as an electrolytic light-emitting element having a structure in which a light-emitting layer in which a small amount of a predetermined activator is dispersed in powder of a predetermined light-emitting substance is sandwiched from above and below inside a plastic or the like. Is included.

Since the inorganic EL light emitting layer can be formed to have a thickness of several microns to several tens of microns, it can be formed as thin as about 0.1 mm even if it is sandwiched between transparent sheets. Therefore, compared to the conventional light guide plate that requires a thickness of about 1 mm,
The thickness can be reduced to about 1/10. In this example, the voltage applied to the electrodes is a relatively high voltage having a pulse property of about + 100V to -100V.

6 (c) and 6 (d) are respectively sectional views showing a structure having another type of organic EL sheet 45 as a sheet-like light source, and graphs showing the applied voltage supplied thereto. . In the layer structure, a transparent sheet is provided on the uppermost layer, and a transparent electrode for applying a constant voltage as shown in FIG. Below that, there is an organic EL (Electro Luminesce) as a light source.
nce) a light emitting layer is adopted, and a transparent electrode is further provided below the light emitting layer by printing. A metal plate forming the cover of the digital camera is also used as the GND electrode on the lowermost layer through the transparent sheet.

That is, the sheet-shaped light source 5 of this example is an electrolytic light-emitting element in which a light-emitting layer in which a small amount of a predetermined activator is dispersed in a powder of a predetermined light-emitting substance is sandwiched between electrodes inside and outside a plastic or the like. It includes an organic EL. Similarly, the thickness of the organic EL light emitting layer can be formed to a few microns to a few tens of microns, so that it can be formed thinner than the conventional light guide plate. In addition, in this example, since the display operation can be performed with a low constant voltage of about 12 V applied, the power saving circuit can be reduced and the power supply circuit can be miniaturized.

The control of the digital camera of the present invention having the above-described configuration will be described. FIG. 7 is a flowchart showing a camera sequence for controlling the digital camera 100. First, from step S1,
The initial screen is displayed (S1), and the display mode is set to the normal state, that is, the imaging / displayable state (S2).

At step S3, the power SW 11 is turned on.
It is determined whether or not it is operated (S3), and if it is in the OFF state, the image display is erased (S4) and the camera operation is stopped. Then, the power consumption is virtually eliminated.

On the other hand, the power SW is returned to the ON state, and it is determined in step S5 whether or not the release SW 10 is pressed (S5). If the release SW 10 is pressed, the process proceeds to step S22 described later. However, if this is not pressed, it is determined in step S6 whether or not the image display mode SW13 is pressed (S6), and if it is the image display mode, the display mode is set to the normal state and then step S11 described later is performed. If it is not, the process proceeds to step S11 described later. The image display mode SW
When is pressed, it is confirmed in step S7 whether or not the image display mode is set (S7). Only in this mode, the display mode is set to the normal state (S8), and the process proceeds to step S11. If not, after changing from the image display mode to the display mode (S9), the image display is turned on (S10). Then, the process proceeds to the next step S11.

In step S11, it is determined whether or not the TV recording / playback mode SW14 has been pressed (S11). If NO, the process proceeds to step S16, which will be described later.
When the V recording / reproducing mode SW is pressed, it is confirmed in step S12 whether or not the recording / reproducing mode is set (S12). Only in this mode, the display mode is set to the normal state (S13), and then the process proceeds to step S16. . If not, after setting the recording / playback mode to the display mode (S1
4) Start desired recording / playback (S15). Then, the process proceeds to the next step S16.

In step S16, the zoom SW is set to T (Tel
It is determined whether or not the position is e (telephoto) or W (Wide: wide angle) (S16). If not, step S31 described later.
However, if it is at the position of T or W, it is processed in the following procedure from step S17. That is, first, it is determined whether or not the normal display can be imaged and displayed (S17),
If it is normal, after zoom control (S18), the process proceeds to step S31. On the other hand, in the case of no, it is judged whether or not the mode is the image display mode (S19). If not here,
Perform high-speed rewind while playing in the W state, and fast-forward fast while playing in the T state (S21).
Move to 31. On the other hand, in the image display mode, W
The previous image is displayed in the state, the next image is displayed in the T state (S20), and the process proceeds to step S31 described later.

From step S22, the following processes are sequentially performed. That is, after setting the display mode to normal (S22), the image pickup circuit is activated (S23), distance measurement is performed (S24), photometry is performed (S25), and the subject is focused based on these (S26), and image pickup is performed. Yes (S2
7) Then, the picked-up image is subjected to image processing to correct defective pixels, white balance, image data compression and storage (S28). After that, the number of captured frames is counted up (S29), and the image display is turned on (S29).
30). Then, the process proceeds to next step S31.

In step S31, it is determined whether or not the image rotation SW 12 for turning the image upside down is turned on (S31). In that case, the image display is rotated 180 ° (S32). In step S33, it is determined whether or not the backlight SW also serving as the brightness setting volume 16 has been operated to the OFF position (S33), and the position is OFF.
In the case of, the backlight is turned off, but in the case of no, the brightness (Hi-
Low) (S34). After that, the process returns to step S3 described above.

As described above, according to the first embodiment, the display member 60 and the light emitting member 5 are respectively connected by the first connecting member 1 and the second connecting member 2 which are connected to the digital camera body 50. Since they are attached so as to be rotatable about the center, they can be independently moved, and especially when used in a dark environment, the light emitting member 5 is used as a backlight light source and the back side of the display member 60 (LCD 3 and diffusion plate 4). Since it can be set around the axis of the second connecting member 2 so as to follow, and light emission can be driven, the content of the liquid crystal screen can be displayed brightly and the display content can be easily viewed. Further, by adopting a transparent sheet, a transparent electrode, or the like, bright outside light can be effectively used as a component of the backlight, and the display quality is improved.

Furthermore, for example, a sheet of organic EL or inorganic EL as an electroluminescent element in which a light emitting layer in which a small amount of a predetermined activator is dispersed in a powder of a predetermined light emitting material is sandwiched between electrodes from above and below in a plastic, for example. The light source 5 is thinner (for example, about 1/10) than a conventional backlight unit using a light guide plate and has a low voltage (12V).
It can be driven to emit light at a certain level, which also contributes to energy saving. Therefore, it is possible to provide a digital camera having a monitor function which is easy to see and which can cope with the surrounding bright and dark situations.

(Second Embodiment) Next, the second embodiment of the present invention will be described.
1 (b) and 8 (a)-(c) for the embodiment.
It will be explained based on. In the digital camera of the second embodiment illustrated in FIG. 1B, the second connecting member (2) constituting the camera of the first embodiment described above is omitted and the configuration is more simply as follows. ing. That is, the digital camera 100 includes a display member 60 including a liquid crystal member 3 for displaying an image, a diffusion plate 4 and a sheet-shaped light emitting member 5, and a first connection for rotatably connecting the display member 60 to the digital camera body 50. Having the member 1, the display member 60,
The digital camera is constructed so that it can be opened and closed on the back side.

When it is bright, the light emitting member 5 is not made to emit light, and only ambient light that enters from the back is used as a backlight to save energy. The light emitting member 5 needs to be substantially transparent, but it is preferable to use an organic EL or the like which is not colored and is colorless and transparent when not emitting light and which emits white light when emitting light (details will be described later). By using an organic EL sheet having a diffusion effect as the transparent member on the LCD side of the organic EL, the diffusion member can also be used, and the thickness of the display portion can be reduced.

FIG. 8A is a perspective view showing the external appearance of the digital camera according to the second embodiment. One of the features of the digital camera 100 is that the organic EL sheet 45 serves as a backlight light source of the LCD (liquid crystal display member) 3, and the light source and the diffusing plate 4 are combined and integrated.
The second connecting member 2 as in the above-described first embodiment is unnecessary, and the configuration is simpler.

FIG. 8B shows the digital camera 100.
FIG. 3 is a cross-sectional view showing the layer structure of the light source sheet used in FIG. L
A diffusion layer is formed under the CD 3, and an organic EL light emitting layer sandwiched between upper and lower transparent electrodes is formed under the diffusion layer. A diffusion plate 4 is formed below it. The lowermost layer is formed with a semi-transmissive sheet that reflects visible light from above and transmits visible light from below.

FIG. 8C is a sectional view showing another example of the layer structure of the sheet light source. The light emitting member 5 serving as a light source is composed of a light emitting layer sandwiched between two sheets, and at least one sheet is made of a plate material having a diffusion function. Specifically, a well-known liquid crystal agent is mixed in this light emitting layer, and a pair of transparent electrodes sandwiching this layer vertically,
Furthermore, it is protected by thin glass or sheet material. On the other hand, a sheet material having a diffusion function is formed in the lowermost layer,
A layer of, for example, an organic EL sheet is formed thereon via a transparent electrode.

As described above, according to the second embodiment, since the entire display member 60 is rotatably supported by only the first connecting member 1, the second connecting member 2 is unnecessary. Therefore, the structure is simpler and the second
The processing and the number of parts related to the connecting member 2 are further reduced. Further, by improving the layered structure of the sheet-shaped light source adopted, the layered structure can be simplified.

The LCD 3 has a thickness of about 1 to 1.4 mm, the organic EL or inorganic EL light emitting layer itself has a thickness of several microns to several tens of microns, and the diffusion plate with a transparent electrode having a thickness of 0.1 mm has a thickness of 0. Even if it is 0.2 to 0.3 mm, the entire thickness of the display member 60 can be formed to be as thin as less than 2 mm. As a result, it is possible to configure the digital camera having the display member 60 having a thickness at least smaller than that of the first embodiment.
Furthermore, the effect regarding display can be expected to be substantially the same as that of the first embodiment or more depending on the member used.

(Modification) The illustrated embodiment may be modified as follows. For example, the content displayed on the display unit of the LCD 3 may be desired information downloaded from a predetermined net with a blue tooth, a mobile phone, or the like, and if it is stored in the memory card 30, it can be used as it is, but the memory card 30 is not always necessary. It is also possible to provide a terminal of a USB or an optical cable without inputting and to enable input as it is. In the future, the sheet-like light source 5 may be a light source which is normally almost completely transparent and emits white light with high brightness as a backlight.

The application of the digital camera 100 is not limited to photographing (imaging) and display (reproduction), but an information terminal which can be easily carried and used for collecting and checking information at any place. Therefore, the portion of the digital camera 100 may also be appropriately modified and implemented as one of the information terminals so as to be easily used in each situation. Besides this, various modifications can be made without departing from the scope of the present invention.
