Description

  The present invention relates to an imaging apparatus.

  In an imaging device such as a digital camera or a mobile phone with a camera function, a display screen such as a liquid crystal monitor is provided. On this display screen, a through image before photographing and a photographed image are displayed. A touch panel may be installed in front of the display screen, and an imaging apparatus capable of inputting various instructions such as change of setting contents from the touch panel has been developed.

  In recent years, downsizing of the imaging apparatus as described above has been progressing. Moreover, in order to improve the visibility of an image, the enlargement of a display screen is desired. For this reason, in an imaging device equipped with a large display screen, a portion (grip space) for gripping the device main body at the time of shooting becomes narrow. For this reason, the user's finger and the display screen overlap at the time of shooting, and the image on the display screen becomes difficult to visually recognize.

In Patent Literature 1, when it is detected that the camera is gripped by the user, the image display area is changed so as not to overlap the grip portion of the touch panel (the portion where the user's finger hits), and the visibility of the image is changed. Techniques for improving the above are described.

The display unit 24 may be provided not only on the back surface of the main body of the digital camera 10 but also on the top surface.

In the digital camera 10 according to the present embodiment, the image displayed on the display unit 24 has two types of screen modes. The screen mode is a setting of the aspect ratio of the through image displayed on the display unit 24. In the present embodiment, “wide display” is set as the first aspect ratio and “4: There are two types of screen modes of “3 display”.
Wide display is a display mode in which the aspect ratio of the display screen is 16: 9. In the case of the touch panel 23 having an aspect ratio of 16: 9 as described above, a through image is displayed on the entire display unit 24 in the case of wide display.

  The external storage I / O unit 29 is configured such that a semiconductor memory such as a flash memory can be attached and detached.

Next, the operation will be described.
3 and 4 are flowcharts of the imaging process executed by the digital camera 10. The imaging process is performed by software processing based on cooperation between the control unit 20 and the program stored in the storage unit 25 when the operation unit 27 instructs the control unit 20 to switch to a shooting mode for shooting a subject. Realized.
In the imaging process, the detection range of the touch panel 23 is changed according to the screen mode of the display unit 24, and various icons for changing the setting contents are displayed on the display unit 24. The following processing is performed by the control unit 20, and the control unit 20 functions as a setting unit, a changing unit, and a display control unit by the imaging process.

  First, the screen mode of the display unit 24 is determined (step S1). As described above, the setting value indicating whether the screen mode is wide display or 4: 3 display is stored in the storage unit 25 in advance. In step S1, the screen mode is determined by referring to the setting value held in the storage unit 25 as described above, and the through image is displayed in this screen mode.

  When the screen mode of the display unit 24 is wide display (step S1; wide), the MENU icon B11 stored in the storage unit 25 is displayed on the display unit 24, and the input from the touch panel 23 is performed on portions other than the icon ( The touch detection is invalidated so as not to be accepted (step S101). Next, the through image of the subject input to the control unit 20 via the imaging unit 21 is displayed on the full screen on the display screen G11 of the display unit 24 (step S102), and the set setting contents are displayed on the display screen G11. It is displayed superimposed on the live view image (step S103).

FIG. 5A shows an example of the display screen G11 displayed on the display unit 24 during wide display. As shown in FIG. 5A, the display screen G11 includes a through image G11a, a MENU icon B11, a setting content display area G11b, and the like.
The through image G11a is a through image of a subject input to the control unit 20 via the imaging unit 21. The MENU icon B11 is an icon displayed in the area where touch detection is enabled in step S101. The setting content display area G11b is the setting content displayed in a superimposed manner on the through image G11a in step S103. In this setting content display area G11b, icons stored in a setting state table T2 to be described later may be displayed, or another icon may be prepared in advance in the storage unit 25 and displayed. Further, in the example of FIG. 5A, only one of the setting contents is displayed, but a plurality of setting contents may be displayed.

  In the example shown in FIG. 5A, the area other than the touch panel 23 corresponding to the MENU icon B11 (in the example of FIG. 5A, the through image G11a and the setting content display area G11b) is displayed in step S101. Touch detection is disabled. The invalidation of touch detection means that when the touch panel 23 is touched and the touched coordinates are input to the control unit 20, the control unit 20 does not determine that the coordinates are touched. The same applies to the following description.

  For example, in the example shown in FIG. 5, from the coordinates corresponding to the area where the MENU icon B11 is superimposed (for example, the area surrounded by a rectangle with (240, 20) and (320, 40) as diagonal lines). Only when the contact is detected, the control unit 20 recognizes that the touch is detected on the touch panel 23, and recognizes that the touch is detected on the touch panel 23 when the contact from the coordinates of the area other than the MENU icon B11 is detected. Will not. The area (coordinates) corresponding to the MENU icon B11 is stored in the storage unit 25 in advance. The control unit 20 refers to the storage unit 25 and does not recognize that the touch panel 23 is touched when coordinates other than the area corresponding to the MENU icon B11 are input from the touch panel 23.

Next, it is determined whether or not a touch operation on the MENU icon B11 is detected (step S104). That is, it is determined whether or not a touch has been detected for an area for which touch detection has not been invalidated in step S101.
When it is determined that a touch operation on the MENU icon B11 is detected (step S104; YES), the setting content table T1 is referred to, and a setting menu is displayed on the right end of the display screen G12 (step S105).

FIG. 6 shows a data storage example of the setting content table T1 that is referred to when the display screen G12 is displayed in step S105.
The setting content table T1 includes a “display coordinate (wide display)” field, a “detection range (wide display)” field, a “display coordinate (4: 3 display)” field, a “detection range (4: 3 display)” field, It consists of a “display state” field, a “setting content (major category)” field, and the like.

The “display coordinates (wide display)” field stores coordinates at which icons corresponding to records are displayed when the screen mode of the display unit 24 is wide display. The coordinates are XY coordinates on the touch panel 23 described above.
The “detection range (wide display)” field stores the coordinates of a range in which an input from the touch panel 23 to the icon corresponding to the record is detected when the screen mode of the display unit 24 is wide display. Specifically, for example, the value “(240,140) − (320,160)” is a rectangle whose diagonal on the line connecting the coordinates (240,140) and (320,160) on the touch panel 23. Indicates that the icon corresponding to the record has been selected from the touch panel 23.
The “display coordinates (4: 3 display)” field stores coordinates at which icons corresponding to records are displayed when the screen mode of the display unit 24 is 4: 3 display.
The “detection range (4: 3 display)” field stores the coordinates of the range in which the input corresponding to the record is detected from the touch panel 23 when the screen mode of the display unit 24 is 4: 3 display. .
In the “display state” field, an icon displayed on the display screen G12 is stored. The icon stored in the “display state” field is an index corresponding to the setting content. In the example shown in FIG. 6, the same icon is used for both wide display and 4: 3 display. Different icons may be used depending on the situation.
In the “setting content (major category)” field, the setting content related to the imaging operation indicated by the icon corresponding to the record is stored. This setting content is associated with a “setting content (major category)” field of a setting state table T2, which will be described later.

FIG. 5B shows an example of the display screen G12 displayed on the display unit 24 in step S105. As shown in FIG. 5B, the display screen G12 includes a through image G12a, setting menu icons B12 to B18, and the like.

  Specifically, in step S105, the setting content table T1 is referred to, and the icon of the “display state” field of the corresponding record is displayed at the coordinates stored in the “display coordinates (wide display)” field. become.

  Returning to FIG. 3, the touch detection from all areas of the touch panel 23 is validated (step S106). Next, a setting content change process is executed according to the touch detection content (step S107).

  FIG. 7 shows a flowchart of the setting content changing process executed in step S107 and step S206 described later. As shown in FIG. 7, first, the screen mode of the display unit 24 is determined (step S301). When the screen mode of the display unit 24 is wide display (step S301; wide), it is determined whether or not a touch from the touch panel 23 is detected in the detection range of the setting menu in wide display (step S302). Specifically, the setting content table T1 is referred to, and it is determined whether or not a touch from an area corresponding to the “detection range (wide display)” field is detected.

  When it is determined that a touch from the touch panel 23 has been detected within the detection range of the setting menu in the wide display (step S302; YES), the setting state table T2 is referred to and a detailed setting icon is displayed on the display screen G13 of the display unit 24. It is displayed (step S303).

  FIG. 8 shows a data storage example of the setting state table T2 referred to in step S303. As shown in FIG. 8, the setting state table T2 includes a “setting content (major category)” field, a “setting content (detail)” field, a “setting flag” field, a “display state (wide display)” field, and a “display coordinate”. (Wide display) field, “detection range (wide display)” field, “display state (4: 3 display)” field, “display coordinates (4: 3 display)” field, and “detection range (4: 3 display)” ) "Field and the like.

In the “setting content (major category)” field, a value corresponding to the “setting content (major category)” field of the setting content table T1 is stored.
In the “setting contents (details)” field, detailed setting contents corresponding to the setting contents of the large category are stored.
The “setting flag” field stores a value indicating whether or not the setting content corresponding to the record is selected. In the present embodiment, “0” indicates a state where no selection is made, and “1” indicates a state where a selection is made. In the example illustrated in FIG. 8, “focus mode” indicates that the setting content is selected as “macro”.
The “display state (wide display)” field stores a detailed setting icon displayed on the display screen G13 when the screen mode of the display unit 24 is wide display. In the “display coordinates (wide display)” field, when the screen mode of the display unit 24 is wide display, coordinates on the touch panel 23 on which the detailed setting icon corresponding to the record is to be displayed are stored. In the “detection range (wide display)” field, when the screen mode of the display unit 24 is wide display, the coordinates of the range in which the input corresponding to the record from the touch panel 23 is detected are stored.
The “display state (4: 3 display)” field stores a detailed setting icon displayed on the display screen G13 when the screen mode of the display unit 24 is 4: 3 display. The “display coordinates (4: 3 display)” field stores coordinates on the touch panel 23 on which the detailed setting icon corresponding to the record is to be displayed when the screen mode of the display unit 24 is 4: 3 display. In the “detection range (4: 3 display)” field, when the screen mode of the display unit 24 is 4: 3 display, coordinates of a range in which an input from the touch panel 23 of an icon corresponding to a record is detected are stored.

FIG. 5C shows an example of the display screen G13 displayed in step S303. As shown in FIG. 5C, the display screen G13 includes a through image G13a, setting menu icons B12 to B18, and detailed setting icons B15a to B15d.
The display screen G13 is the same as the through image G13a, and the setting menu icons B12 to B18 are the same as the through image G12a and the setting menu icons B12 to B18 of the display screen G12, respectively.
The detailed setting icons B15a to B15d are detailed setting icons that are displayed when it is determined in step S302 that a touch has been detected in the setting menu. Detailed setting icons B15a to B15d shown in FIG. 5C indicate the case of the detailed setting icon displayed when a touch on the setting menu icon B15 is detected in step S302. When a touch on other setting menus (setting menu icons B11 to B14 and setting menu icons B16 to B18) is detected, the “display state (wide display)” field of the setting state table T2 is referred to and the same detailed setting is made. An icon is displayed.

In step S303, specifically, the setting content (major category) corresponding to the setting menu in which the touch is detected in step S302 is referred to. For example, when the setting menu icon B15 is touched on the display screen G12, the value of “focus mode” is referred to from the “setting contents (major category)” field of the setting contents (wide display) table T1. Then, a record in which the value of the “setting content (major category)” field of the setting state table T2 is “focus mode” is extracted. Detailed setting icons B15a to B15d are displayed by displaying the detailed setting icons of the “display state (wide display)” field at the position of the value of the “display coordinates (wide display)” field of the extracted record. It will be.
In the example of the display screen G13 shown in FIG. 5C, the detailed setting icon B15b corresponding to the record whose “setting flag” in the setting state table T2 is “1” indicates the currently set content. A shaded display is shown.

  Returning to FIG. 7, whether or not a touch is detected for the detection range of the detailed setting icon on the touch panel 23 (in the case of the display screen G13 shown in FIG. 5C, the detection range corresponding to the detailed setting icons B15a to B15d). Is determined (step S304). When it is determined that a touch is detected in the detection range of the detailed setting icon (step S304; YES), the setting content corresponding to the detection range is set (step S305). Specifically, the “detection range (wide display)” field of the setting state table T2 is referred to, and the value of the “setting flag” field of the record that matches the detection range in which the touch is detected becomes “1”. And the value of the “setting flag” field of the record having the same value in the “setting content (major category)” field is “0”. In the example of the display screen G3 shown in FIG. 5C, for example, when the detailed setting icon B5a is touched, the “setting flag” field of the record whose value of the “setting content” field of the setting state table T2 is “AF” The value in the “setting flag” field of the record in which the value of the “setting content” field is “macro” is “0”.

  Next, the setting content table T1 is updated based on the setting condition changed in step S305, and the display screen G14 is displayed on the display unit 24 (step S306). Specifically, the icon selected in step S304 (the detailed setting icon B15a in the example of FIG. 5) is stored in the “display state” field of the setting content table T1, and the setting menu icon B15 is updated to the icon. . A display screen G14 is displayed based on the updated contents.

FIG. 5D shows an example of the display screen G14 displayed in step S306. Since the configuration of the display screen G14 shown in FIG. 5D is the same as that of the display screen G12, description thereof is omitted.
The example shown in FIG. 5D shows an example of the display screen G14 displayed in step S306 when the detailed setting icon B15a is touched on the display screen G13 shown in FIG. The setting menu icon B15 is changed to an icon corresponding to the detailed setting icon B15a and displayed.

  On the other hand, when it is not determined that a touch from the touch panel 23 has been detected in the setting menu of the display screen G12 (step S302; NO), it is not determined that a touch has been detected for the detection range of the detailed setting icon (step S304; NO). ), The process proceeds to step S108.

  Returning to FIG. 3, it is determined whether or not a touch operation in an area other than the area where the setting menu is displayed is detected (step S108). Here, the area other than the area where the setting menu is displayed indicates an area of the touch panel 23 other than the setting menu icons B12 to B18 on the display screen G12, and the setting menu icons B12 to B12 on the display screen G13. Regions other than B18 and detailed setting icons (in the example of FIG. 5C, detailed setting icons B15a to B15d are shown) are shown.

If it is determined that a touch operation in an area other than the area where the setting menu is displayed is detected (step S108; YES), the process returns to step S101.
If it is not determined that a touch operation in an area other than the area where the setting menu is displayed is detected (step S108; NO), the process returns to step S107.

On the other hand, when it is not determined that a touch operation on the MENU icon B11 is detected (step S104; NO), it is determined whether a half-press operation on the shutter key of the operation unit 27 is detected (step S109).
When it is determined that a half-press operation on the shutter key of the operation unit 27 has been detected (step S109; YES), the setting state table T2 is referred to, and processing is performed based on each setting content (step S110). Specifically, for example, if “focus mode” is “AF”, AF processing is performed, AE (Automatic Exposure) processing is performed with reference to “exposure value”, and “white balance” is set to “automatic”. If it is “white balance”, AWB processing or the like is performed.

  Next, it is determined whether or not a full press operation on the shutter key of the operation unit 27 has been detected (step S111). When it is determined that a full press operation on the shutter key of the operation unit 27 is detected (step S111; YES), an imaging instruction is input to the control unit 20 by the full press operation, and input via the imaging unit 21. The image data of the subject being subjected to compression coding is encoded by the image processing unit 26 and stored in the storage unit 25 (step S112), and the process returns to step S102.

When it is not determined that the full press operation on the shutter key of the operation unit 27 is detected (step S111; NO), it is determined whether the release of the half press operation on the shutter key is detected (step S113).
If it is determined that the release of the half-press operation on the shutter key has been detected (step S113; YES), the process returns to step S102. If it is not determined that the release of the half-press operation on the shutter key has been detected (step S113; NO), the process returns to step S111.

If it is not determined that a half-press operation on the shutter key of the operation unit 27 has been detected (step S109; NO), it is determined whether an instruction to release the shooting mode is input from the operation unit 27 to the control unit 20. (Step S114).
If it is not determined that an instruction to cancel the shooting mode is input (step S114; NO), the process returns to step S102.
If it is determined that an instruction to cancel the shooting mode is input (step S114; YES), the process ends.

The processing described above is a case where the screen mode of the display unit 24 is wide display. Hereinafter, a case where the screen mode of the display unit 24 is 4: 3 display will be described.
When the screen mode of the display unit 24 is 4: 3 display (step S1; 4: 3), the process proceeds to FIG. 4, and touch detection is invalidated for portions other than the grip area E1 of the touch panel 23 (step S201). A through image G21a of the screen G21 is displayed (step S202).

FIG. 9A shows an example of the display screen G21 displayed in step S202. As shown in FIG. 9A, the display screen G21 includes a through image G21a and a grip area E1.
The through image G21a is an image of the subject input to the control unit 20 via the imaging unit 21, and is displayed in 4: 3 display in the case of the display screen G21.
The grip area E1 is an area other than the area where the through image G21a is displayed in the display screen G21. In the present embodiment, in the 4: 3 display, the through image G21a is displayed in a region surrounded by a rectangle whose diagonal is a line connecting coordinates (0, 0) and (240, 180). In the example shown in FIG. 9A, a grip area E1 is a region surrounded by a rectangle whose diagonal is a line connecting coordinates (240, 0) and (360, 180). Note that the grip area E1 is not limited to the present embodiment as long as it is a region where touch detection is enabled in the 4: 3 display through image display state.
In the area other than the grip area E1 (in the example of FIG. 9A, the area of the through image G21a), the touch detection is invalidated in step S201.

  Next, it is determined whether or not a predetermined touch duration has been detected for a predetermined position in the grip area E1 (step S203). The position (coordinates) and time are stored in advance in the storage unit 25, and values are held. In step S203, for example, whether or not the touch area from the touch panel 23 has elapsed for 3 seconds with respect to the grip area E1 or the like. Will be judged. The predetermined position of the grip area E1 may be the entire grip area E1, or a specific position that the user can easily touch may be determined in advance.

  When it is determined that the touch duration for a predetermined time has been detected for the predetermined position in the grip area E1 (step S203; YES), the setting content table T1 is referred to and the left column of the grip area E1 on the display screen G22 is displayed. A setting menu is displayed (step S204). Specifically, the “display coordinate (4: 3 display)” field of the setting content table T1 is referred to, and the icon stored in the “display state” field is displayed at this coordinate.

  FIG. 9B shows an example of the display screen G22 displayed in step S204. As shown in FIG. 9B, the display screen G22 includes a through image G22a, setting menu icons B22 to B28, a grip area E1, and the like. Since the through image G22a and the setting menu icons B22 to B28 have substantially the same configuration as the display screen G12, the description thereof is omitted. However, as shown in FIG. 9B, the position where the setting menu icons B22 to B28 are displayed on the display screen G22 is different from the display screen G12. This is because the coordinates stored in the “display coordinates (wide display)” field and the “display coordinates (4: 3 display)” field of the setting content table T1 are different.

  Next, touch detection of the entire touch panel 23 is validated (step S205). When the touch detection from the touch panel 23 in the area where the setting menu is displayed is validated, the setting content changing process corresponding to the touch detection content is executed (step S206), as in step S107.

  Returning to FIG. 7, the setting content changing process executed in step S206 will be described. Since the screen mode is 4: 3, it is determined in step S301 that the screen mode of the display unit 24 is 4: 3 display (step S301; 4: 3), and the setting menu is detected in the 4: 3 display. It is determined whether or not a touch from the touch panel 23 is detected in the range (step S312). The processing in step S312 is substantially the same as that in step S302, but differs from step S302 in that the “detection range (4: 3)” field of the setting content table T1 is referred to. In the present embodiment, the value stored in the “detection range (4: 3)” field is associated with the position of the grip area E1.

  The process in step S312 is substantially the same as the process in step S302, but the “display state (4: 3)” field and “display coordinate (4: 3)” field of the setting state table T2 are referred to, and the display screen G23 is displayed. It is different from step S303 in that it is displayed.

  FIG. 9C shows an example of the display screen G23 displayed in step S313. The configuration of the display screen G23 is substantially the same as that of the display screen G13. As described above, since the value of the “detection range (4: 3)” field of the setting state table T2 is associated with the grip area E1, the detailed setting icons B15a to B15a˜ are associated with the touch position of the grip area E1. B15d is displayed. In this state, when the touch position of the grip area E1 is slid (that is, the user slides the finger up and down while touching the touch panel 23), the movement of the touch position and “detection range (4: 3)” in the setting content table T2 are performed. The detailed setting icon of the record whose value stored in the field matches is displayed in the same manner.

The subsequent processes in steps S314 to S316 are substantially the same as those in steps S304 to S306, respectively, and a description thereof will be omitted.
FIG. 9D shows an example of the display screen G24 displayed in step S316. The example shown in FIG. 9D shows a case where the detailed setting icon B25a is selected on the display screen G23. Similar to the display screen G14, the icon is changed to an icon corresponding to the selected detailed setting icon B25a.

  Further, the processing in step S207 to step S213 after step S206 shown in FIG. 4 is the same as that in step S108 to step S114, respectively, and thus the description thereof is omitted.

  As described above, in the digital camera 10 according to the present embodiment, when the screen mode is wide display, the setting menu is displayed when the MENU icon is touched, and when the screen mode is 4: 3 display, the grip is displayed. A setting menu is displayed when touch persistence is detected in area E1. Therefore, when the digital camera 10 is gripped at the time of shooting, the touch detection of the portion touched by the touch panel 23 is invalidated, so that erroneous input that touches the setting menu by mistake at the time of shooting can be prevented. In addition, since the setting menu is not displayed on the display unit 24 at the time of shooting, the through image can be displayed on the entire display screen 24, the visibility is improved, and the setting menu is displayed only when necessary so that the setting can be made. It can be carried out.

  Further, since the touch detection range from the touch panel 23 is changed according to the screen mode, it is possible to prevent erroneous input according to the screen mode set by the user, and on the display screen of the display unit 24. The area can be used as a grip space, and the digital camera 10 can be securely grasped and photographed.

  In the case of 4: 3 display, since it is determined whether or not to select the setting menu according to the touch detection of the grip area E1, selection of setting contents is performed by effectively using an area where it is not necessary to display a through image. The operation can be performed.

  Note that the description in the present embodiment shows an example of the present invention, and the present invention is not limited to this. For example, although the digital camera 10 has been described as an example in the present embodiment, a mobile phone or the like provided with a camera function and a touch panel may be used, and the description in the present embodiment does not limit the present invention. .

  Moreover, although the touch panel 23 gave the coordinate shown in FIG. 2 as an example, it is not restricted to this. It is only necessary that the detection range from the touch panel 23 can be changed according to the screen mode, and the touch panel 23 having another aspect ratio may be used.

  Further, in the present embodiment, the setting menu is displayed when the MENU icon B11 is touched in the case of wide display, but it may be a contact from a predetermined specific touch panel 23, It is not limited to this. For example, even in the case of wide display, as in the case of 4: 3 display in the present embodiment, the setting menu may be displayed when a predetermined time has elapsed in touch maintenance in the grip area E1. Good. Similarly, in the case of 4: 3 display, it may be a contact from a predetermined specific touch panel 23.

  In the present embodiment, the grip area E1 in the case of 4: 3 display is displayed on the right side of the through image. However, the position of the grip area may be a predetermined area of the touch panel 23, and is not limited thereto. I can't. For example, when the shutter key is provided on the left side toward the touch panel 23, the through image may be displayed on the right side of the display unit 24 and the grip area E1 may be on the left side.

  Further, the information stored in the setting content table T1 and the setting state table T2 in the present embodiment is not limited to this as long as the information of the detection range for displaying the setting menu is stored. For example, in the present embodiment, the screen mode has been described based on the wide display and the 4: 3 display. However, when there is a function of another screen mode, a setting menu corresponding to the screen mode is displayed. The detection range information may be stored.

  In addition, the detailed configuration and detailed operation of each device constituting the digital camera 10 according to the present embodiment can be changed as appropriate without departing from the spirit of the invention.
