Description

  The present invention relates to a photographing apparatus including a display and a touch panel.

  In recent years, digital cameras, portable information devices having a photographing function, and the like are widely used as photographing devices for photographing a subject. Many of these apparatuses include a touch panel on a display screen that displays an image of a subject. A predetermined input can be performed by touching the touch panel with a finger, a stylus, or the like.

  For example, in the digital camera device disclosed in Patent Document 1, focusing is performed by touching an image of a subject displayed on a liquid crystal display unit with a touch panel with a finger. In this apparatus, a focusing area for focusing is set around a point touched by a finger. A photometric area can also be set around the same point, and exposure adjustment is performed based on information in the photometric area.

  Further, in the electronic camera disclosed in Patent Document 2, a frame is provided on a person's face image displayed on the liquid crystal monitor, and a main subject at the time of shooting is selected by bringing a finger into contact with the frame.

  However, when a touch panel is used for input of the photographing apparatus, an erroneous input operation tends to occur more easily than a physical button or key. Specifically, even when the user unintentionally touches the touch panel, an operation related to shooting occurs, or even if the user performs an input operation, a desired function is not activated and a redo operation is required.

  For this reason, for example, the photographing operation, that is, the operation of releasing the shutter is not activated in Patent Documents 1 and 2 by an operation on the touch panel with a finger. Shooting is particularly desired to avoid malfunction, and is usually performed via a physical shutter button (shutter key). For example, even in Patent Document 2, photographing is performed through a physical operation member. As a result, both physical buttons (keys) and a touch panel are required to perform shooting while suppressing malfunctions as much as possible.

  On the other hand, when this physical shutter button is used in order to avoid a malfunction, a focus operation is performed by a finger operation on the touch panel, and a shooting operation is performed by a finger operation on the physical button. Therefore, the focus and photographing operation that are originally desired to be activated by a series of operations are due to the separated operations, and it cannot be said that the operability is good.

It is a functional block diagram which shows one Embodiment of the portable information device by this invention. 3 is a flowchart illustrating an embodiment of a photographing method according to the present invention.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  The photographing apparatus according to the present invention includes a display and a touch panel. The present invention is characterized in that a shooting icon is displayed on the screen of the display, and the shooting operation is activated by pressing the shooting icon with a finger. Here, in order to activate the focus operation and the shooting operation, it is necessary to push the finger with the shooting icon instead of a simple finger contact, so that an erroneous operation due to unintentional or unintentional contact is avoided.

  In addition, since the focus operation and the shooting operation are activated by a series of operations with a finger on the shooting icon (touch panel) (pushing operation in the same position range), high operability is realized. Furthermore, since the shooting icon is not a physical button or key but an image displayed on the screen, its position and size can be made variable. Accordingly, it is possible to set so that the photographing icon can be surely pushed by the finger of the hand holding the apparatus, regardless of whether the apparatus is oriented vertically or horizontally during photographing.

  In the photographing apparatus targeted by the present invention, the photographing operation is activated when the user's finger contacts the touch panel. The touch panel enables various functions other than the photographing function of the device. For this reason, most of the imaging devices provided with a touch panel are portable information devices such as smartphones that can be held and operated by hand. Therefore, hereinafter, a portable information device with a photographing function (hereinafter referred to as a portable information device) will be described as an embodiment of the present invention.

  FIG. 1 is a front view and a rear view of a portable information device according to the present invention.

  FIG. 1A is a front view of the portable information device 1. According to the front view, an image including an image display area 104, a shooting icon 105, a zoom icon 106, a mode selection icon 107, and a cross icon 108 is displayed on the screen of the display 101. Further, on this screen, a touch panel 100 that sequentially outputs a finger contact position as time passes is arranged.

  The image display area 104 is an area for displaying an image of a subject. For example, it may be designed to imitate a physical liquid crystal screen that a conventional digital camera has. In the image display area 104, an image (moving image) of the subject at the time of shooting is displayed. It is also preferable that the captured image is displayed as a reproduced image.

  The shooting icon 105 is a display for invoking a shooting operation. For example, it may be designed to imitate a physical shutter button that a conventional digital camera has. When the user's finger performs a half-pressing operation of pressing the shooting icon 105 with a pressing force within a predetermined range, a focusing operation for focusing on the subject is activated. Subsequently, when the user's finger performs a pushing operation of pushing the photographing icon 105 with a pressing force equal to or greater than a predetermined threshold, a photographing operation for capturing an image of the subject is activated.

  The zoom icon 106 is a display for invoking a zoom operation. For example, it may be designed to imitate a physical zoom button of a conventional digital camera. When the user's finger presses the zoom icon 106, the image displayed in the image display area 104 is telephoto (zoomed in) or wide-angle (zoomed out) at a zoom speed corresponding to the magnitude of the pressing force. .

  The mode selection icon 107 is a display for selecting one from a mode group including various modes that the portable information device 1 can take. For example, it may be designed to imitate a physical mode change switch that a conventional digital camera has. When the user's finger moves (slides) while pressing the mode selection icon 107 with a pressing force equal to or greater than a predetermined threshold, one of the set mode groups is selected according to the contact position of the moved finger. Operate.

As modes that can be selected by the mode selection icon 107,
(A) a shooting mode for invoking a shooting operation;
(B) It is preferable that a playback mode for invoking a playback operation for playing back a captured image is provided. In addition, shooting modes are further divided
(C) an autofocus shooting mode for activating the autofocus function;
(D) It is also preferable that a manual photographing mode for manually performing focus and exposure adjustment is provided. In this case, the operation of pressing the shooting icon 105 described above is performed under the operation of (c) autofocus shooting mode.

  The cross icon 108 is a display for designating a portion of the subject image to be focused with a cursor. For example, it may be designed to imitate a physical cross key of a conventional digital camera, and may have four up / down / left / right movement key images and an input key image located in the center. For example, the four movement key images are appropriately pressed with a finger to move the cursor displayed in the image display area 104 to a position to be focused, and the input key image is pressed with the finger to select a focus area in the image display area 104. decide.

  The shooting icon 105, the zoom icon 106, the mode selection icon 107, and the cross icon 108 are all preferably displayed within the range where the finger of the hand holding the device 1 can be easily reached. This finger is actually a thumb not related to holding. Here, according to FIG. 1 (A), the portable information device 1 is operated with the finger of the held right hand. In this case, considering the range in which the thumb can easily reach, all of the above four icons are displayed on the “right side to the front” in the screen of the display 101 (the right side when facing the front of the device 1). .

  Note that, depending on the case where the portable information device 1 is operated with the finger of the left hand held, any of the above four icons is displayed on the “front left side” in the screen of the display 101 (facing the front of the device 1 directly. It is also preferable that display is possible on the left side).

  Normally, the information processing and communication functions of the portable information device 1 can be activated by operating the touch panel 100 with a finger (thumb) of the hand holding the device 1. Therefore, it is very convenient that the function as the photographing apparatus can be activated by the operation with the finger without the need to change the device 1.

  FIG. 1B is a rear view of the portable information device 1. According to this rear view, a lens module 109 is provided as a light receiving unit that takes light from a subject into the device 1. The lens module 109 is positioned “on the left side of the front surface” (right side in FIG. 1B) in the back surface of the device 1. Here, when the lens module 109 is positioned “on the right side in front” with the device 1 turned upside down and operated with the finger (thumb) of the left hand, the shooting icon 105, the zoom icon 106, and the mode selection icon 107 are displayed. The cross icon 108 is displayed on the “front left side” in the screen of the display 101 so that the finger of the left hand can easily reach.

  The image display area 104 can also be displayed at a desired position in the touch panel 100, like the shooting icon 105 and the like. For example, it is also preferable to display the image display area 104 so as to be located directly behind the lens module 109 as viewed from the user. In this case, the user can use the device 1 with the feeling that the light from the subject is directly received by the image display area 104 via the lens module 109.

  FIG. 2 is a front view and a rear view showing another usage mode of the portable information device according to the present invention.

  FIG. 2A is a front view of the portable information device 1. According to the front view, an image including an image display area 104, a shooting icon 105, a zoom icon 106, a mode selection icon 107, and a cross icon 108 is displayed on the screen of the display 101.

  All of the above four icons are within the range where the finger (thumb) of the hand holding the portable information device 1 can be easily reached, and are displayed on the lower side of the screen. Even when the device 1 is held with the left hand, these four icons are displayed on the lower side of the screen of the display 101.

  FIG. 2B is a rear view of the portable information device 1. According to the rear view, the lens module 109 is located on the upper side in the rear surface of the device 1. Thereby, even if the portable information device 1 is held with the right hand or the left hand as shown in the figure, it is possible to avoid a situation where the finger of this hand blocks the objective lens of the lens module 109. As a result, it is possible to perform good shooting without unnecessary obstacles.

  As described above with reference to FIGS. 1 and 2, in the present invention, the shooting icon 105, the zoom icon 106, the mode selection icon 107, and the cross icon 108 that are operation targets are all displayed on the display 101. These are virtual buttons (switches, keys) displayed on the screen. As a result, these icons can be arranged within a range where fingers of the hand holding the portable information device 1 can be easily reached. Thereby, various operations relating to photographing can be activated by an operation with a finger of the hand holding the device 1.

  Further, since the positions of these icons are variable, for example, even if the portable information device 1 is in the horizontal direction (FIGS. 1A and 1B) at the time of shooting, the vertical direction (FIGS. 2A and 2B) )), It is possible to arrange so that these icons can be pushed in with the finger of the hand holding the device.

  FIG. 3 is a front partial view of a portable information device and a schematic diagram of an operation with a finger for explaining a shooting icon of the present invention.

  FIG. 3 (A1) shows a portion where the shooting icon 105 is displayed in the portable information device 1. According to FIG. 3 (A1), the shooting icon 105 is displayed on the screen of the display 101 at a position where the finger (thumb) of the held hand can push the shooting icon 105.

When shooting, the user first touches the shooting icon 105 with a finger. That is, the contact position of the finger overlaps the display position range of the shooting icon 105. Next, the user presses the shooting icon 105 with his / her finger in order to focus on the subject while checking the image displayed in the image display area 104. At this time, as shown in FIG. 3 (A2), the pressing force p _C by the finger is set such that the first threshold value is p _TH1 and the second threshold value is p _TH2 .
(1) p _TH2 > p _C ≧ p _TH1
It is a value that satisfies the condition.

Here, the first threshold p _TH1 is set to a value in the range of, for example, 0.5N (Newton) to 1.0N, and the second threshold p _TH2 is set to a value in the range of, for example, 1.0N to 2.0N. It can be. The finger pressing force p _C is detected by a pressing force detection unit 103 (FIG. 5) described later.

When viewed from the user's operation, pressing with the pressing force p _C satisfying the expression (1) corresponds to half-pressing of a physical shutter button imaginary by the shooting icon 105. Thereby, the focus operation is activated. The focus operation is an operation for focusing on a desired position in the subject image. For example, the cursor is displayed in the image display area 104, and the focus is adjusted in an image in a predetermined focus area centered on the position designated by the cursor. The cursor (focus area) may be set in advance at a predetermined position, for example, the center of the image display area 104.

Next, the user further presses the shooting icon 105 with his / her finger in order to perform shooting while confirming that the subject is in focus. At this time, the pressing force p _C by this finger is also shown in FIG. 3 (A2),
(2) p _C ≧ p _TH2
It is a value that satisfies the condition.

When viewed from the user's operation, depression of a pressing force p _C satisfying the formula (2) are shot icon 105 corresponds to pushed the physical shutter button virtual. As a result, the photographing operation is activated. The shooting operation is an operation for capturing an image of a subject. For example, the optical information from the lens module 109 is captured (imaged) by taking it into an imaging unit 111 (FIG. 5) described later for a set shutter time.

As described above, in the portable information device 1 of the present invention, the user's finger presses the shooting icon 105 with the pressing force p _C that satisfies the condition (p _TH2 > p _C ≧ p _TH1 ) of the expression (1). When the half-push operation is performed, the focus operation is activated. Subsequently, when a pushing operation is performed with a pressing force p _C that satisfies the condition (p _C ≧ p _TH2 ) of the expression (2), the photographing operation is activated. In this way, the user can obtain a realistic operation feeling as if the physical shutter button in the conventional digital camera was actually pressed.

Further, in the portable information device 1 of the present invention, the magnitude of the pressing force p _C by the finger is added to the operation conditions. That is, in order to activate the focus operation and the photographing operation, it is necessary to press the photographing icon 105 with a finger instead of a simple finger contact. As a result, malfunction caused by unintentional or unintentional contact can be avoided, and photographing with malfunctions suppressed can be performed. Furthermore, a responsive operation that is not just contact is possible.

  Furthermore, since the focus operation and the shooting operation are activated by a series of operations with the finger (pressing operation in the same position range) on the shooting icon 105 (touch panel 100), high operability is realized.

In determining whether or not to activate the focus operation, the condition of the formula (1) is not actually used, and as shown in step S605 (FIG. 6) described later,
(3) p _C ≧ p _TH1
Is used. This is because the present embodiment is premised on the operation in (c) autofocus shooting mode. That is, even when the user suddenly pushes in with a strong pressing force p _C (p _C ≧ p _TH2 ), the focusing operation is surely activated in advance.

Here, the first threshold value p _TH1 is preferably a finite value (p _TH1 > 0). Thereby, the user can obtain a realistic operational feeling that the focus operation is activated by a half-pressing operation that requires a certain amount of pressing. However, it is also possible to set this threshold value p _TH1 to zero. In this case, the focus operation is substantially activated when the finger touches the shooting icon 105.

  Further, the tactile response mechanism 102 (FIG. 5), which will be described later, can give the finger a vibration that makes the user feel the presence of the physical shutter button before and after the time when the focus operation is activated. Thereby, the user can feel that the half-press operation has been accepted, and can obtain a reliable operation feeling.

Here, examples of vibrations that make the user feel the presence of a physical shutter button include the following. First, when the pressing force p _{C applied} to the photographing icon 105 by the finger increases, a vibration v ₁ that increases with the magnitude of the pressing force p _C is applied to the finger. Then, close the pressing force _{p C} is the first threshold value _{p TH1,} further comprising a first threshold value or more _{p TH1,} strength of vibration _{v 1} rapidly increases. As a result, the finger feels as if the finger is pressed to the point where the shutter button is lightly hit.

  Further, the tactile response mechanism 102 (FIG. 5) may give the finger a vibration that gives a feeling as if the physical shutter button was actually pressed before and after the time when the photographing operation is activated. it can. Thereby, the user can feel that the push-in operation has been accepted, and can obtain a reliable operation feeling.

Here, examples of vibrations that give a feeling as if the physical shutter button was actually pressed are as follows. Finger during focusing operation is subjected to vibration v ₁ is pushed shooting icon 105 in a stronger pressing force p _C. Thereby, when the pressing force p _C approaches the second threshold value p _TH2 , a vibration v ₂ that increases with the magnitude of the pressing force p _C is given to the finger. The intensity of the vibration v ₂ is set larger than the intensity of the vibration v ₁ .

Next, when the pressing force p _C becomes _{equal to} or higher than the second threshold value p _TH2 , the intensity of the vibration v ₂ is rapidly reduced. As a result, the finger feels as if the shutter button, which has been pushed lightly, is further pushed in and finally pushed out.

  FIGS. 3B and 3C show various modes of the shooting icon 105 displayed on the display 101 of the portable information device 1. As shown in FIG. 3B, the position of the shooting icon 105 on the display 101 is variable so that the finger (thumb) of the hand holding the device 1 can easily push the shooting icon 105. It is preferable that

  In general, photographing is particularly desired to avoid a malfunction, and has been conventionally performed via a physical shutter button. Therefore, when shooting is performed via the shooting icon 105 as in the present invention, it is preferable that the position of the shooting icon 105 is variable and the shooting icon 105 is displayed at an appropriate position. This is even more so when the finger performing the operation is the finger of the hand holding the device 1. As a result, a reliable operation in which malfunctions are suppressed is ensured.

  Further, the size (area of the display position range) of the shooting icon 105 on the screen of the display 101 is variable so that the finger (thumb) of the hand holding the device 1 can push the shooting icon 105. Is preferred. Furthermore, it is also preferable that the shape of the shooting icon 105 can be set as appropriate.

  For example, the shooting icon 105 in FIG. 3C has a larger area than the shooting icon 105 in FIG. 1A, and the shape is not circular, and covers the reach of the thumbtip. Fan-shaped or L-shaped. As a result, a reliable operation in which malfunctions are suppressed is possible.

  FIG. 4 is a front partial view of a portable information device and a schematic diagram of a finger operation for explaining the zoom icon and the mode selection icon of the present invention.

  FIG. 4A1 shows a portion where the zoom icon 106 is displayed in the portable information device 1. According to FIG. 4 (A1), the zoom icon 106 is displayed on the screen of the display 101 at a position where the held hand finger (thumb) can easily push the zoom icon 106.

When zooming, first, the user touches the zoom icon 106 with a finger. That is, the finger contact position overlaps the display position range of the zoom icon 106. Specifically, the zoom icon 106 overlaps with the display position range of either the wide-angle (wide) instruction portion W or the telephoto (television) instruction portion T. Next, the user presses the zoom icon 106 with a finger to obtain an image with a desired display magnification while confirming the image displayed in the image display area 104. Specifically, as shown in FIG. 4 (A2), either the wide-angle instruction portion W or the telephoto instruction portion T is pressed with the pressing force p _C.

Here, when the wide-angle instruction portion W is pressed, a zoom speed determination unit 123 (FIG. 5) to be described later zooms to the wide-angle side (decreases the display magnification) based on the magnitude of the pressing force p _C. Determine the zoom speed. For example, when the pressing force p _C is equal to or greater than the threshold value p _THW , the zoom speed can be increased in proportion to the value of (p _C −p _THW ). In this case, the more the finger is pushed, the faster the subject image is zoomed to the wide-angle side in proportion to that amount.

When the telephoto instruction portion T is pressed, the zoom speed determining unit 123 (FIG. 5) also performs zooming to the telephoto side (increasing the display magnification) based on the magnitude of the pressing force p _C. Determine the speed. For example, when the pressing force p _C is equal to or greater than the threshold value p _THT , it is possible to increase the zoom speed in proportion to the value of (p _C −p _THT ). In this case, the more the finger is pushed, the faster the subject image is zoomed to the telephoto side in proportion to that amount.

  It is also preferable that the wide-angle instruction portion W and the telephoto instruction portion T of the zoom icon 106 are displayed so as to enter the device 1 (as if they are depressed) when pressed with a finger.

  FIG. 4 (B1) shows a portion of the portable information device 1 where the mode selection icon 107 is displayed. According to FIG. 4 (B1), the mode selection icon 107 is displayed on the screen of the display 101 at a position where the held hand finger (thumb) can easily press the mode selection icon 107. Note that modes selectable by the mode selection icon 107 include, for example, an autofocus shooting mode, a manual shooting mode, and a playback mode as described above.

  When selecting a mode, first, the user touches the mode selection icon 107 with a finger. That is, the contact position of the finger is superimposed on the display position range of the mode selection icon 107. Specifically, for example, it overlaps with the display position range of the slider portion of the mode selection icon 107. Next, in order to operate a desired mode, the user moves (slides) the finger while pressing the slider portion with the finger.

At this time, as shown in FIG. 4 (B2), the pressing force p _C by the finger has a third threshold value p _TH3 ,
(4) p _C ≧ p _TH3
It is a value that satisfies the condition. Here, the third threshold value p _TH1 can be set to a value within a range of 0.5N to 2.0N, for example.

In FIG. 4 (B1), a triangular mark indicates this position. Thereby, the slider part also slides with the finger. As described above, the contact position of the finger moves and is superimposed on one of a plurality of positions corresponding to each mode. As a result, a mode corresponding to this superimposed position operates.

  As described above, in the portable information device 1 of the present invention, the user's finger operates while pressing each of the zoom icon 106 and the mode selection icon 107. As a result, the user can obtain a realistic operational feeling as if he / she actually operated a physical zoom button or a mode switch on a conventional digital camera. In addition, a responsive operation that is not mere contact is possible, and malfunctions are suppressed.

  Furthermore, during a zoom operation, a tactile response mechanism unit 102 (FIG. 5), which will be described later, can give a vibration of intensity according to the zoom speed to the finger. For example, the finger is given a vibration that becomes stronger as the zoom speed increases. Thereby, the user can feel that the zoom operation has been accepted, and can obtain a reliable operation feeling.

  Further, at the time of mode selection, a tactile response mechanism 102 (FIG. 5), which will be described later, can apply vibration to the finger according to the position of the slider portion of the mode selection icon 107. For example, when the slider portion has been slid to a position for designating a predetermined mode, a short-time vibration (such as reminiscent of a clicking sound) is given to the finger. As a result, the user can obtain a feeling that the slider portion is in a predetermined position, can feel that the mode selection operation has been accepted, and can obtain a reliable operation feeling.

  The zoom icon 106 and the mode selection icon 107 are not limited to the above-described embodiment. For example, the mode selection icon 107 may be designed to imitate a plurality of button groups, dials, and the like. In any case, one of the mode groups is operated in accordance with the position where the finger contact position is superimposed within the display position range of the mode selection icon 107.
