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

FIG. 1A is a block diagram showing a system configuration example of a digital camera 100 as an example of a device to which the embodiment of the present invention can be applied. Further, FIG. 1B is an external view of the digital camera 100.

In FIG. 1, the photographing lens 104 is a lens group including a zoom lens and a focus lens. The shutter 105 is a shutter having an aperture function. The image pickup unit 106 is an image pickup device composed of a CCD, a CMOS element, or the like that converts an optical image into an electric signal. The A / D converter 107 converts an analog signal into a digital signal. The A / D converter 107 is used to convert an analog signal output from the imaging unit 106 into a digital signal. The barrier 103 covers the imaging system including the photographing lens 104 of the digital camera 100 to prevent the imaging system including the photographing lens 104, the shutter 105, and the imaging unit 106 from being soiled or damaged.

The image processing unit 102 performs resizing processing such as predetermined pixel interpolation and reduction and color conversion processing on the data from the A / D converter 107 or the data from the memory control unit 108. Further, in the image processing unit 102, a predetermined calculation process is performed using the captured image data, and the system control unit 101 performs exposure control and distance measurement control based on the obtained calculation result. As a result, TTL (through-the-lens) AF (autofocus) processing, AE (autoexposure) processing, and EF (flash pre-flash) processing are performed. Further, the image processing unit 102 performs a predetermined calculation process using the captured image data, and also performs a TTL method AWB (auto white balance) process based on the obtained calculation result.

The output data from the A / D converter 107 is written directly to the memory 109 via the image processing unit 102 and the memory control unit 108, or via the memory control unit 108. The memory 109 stores image data obtained by the imaging unit 106 and converted into digital data by the A / D converter 107, and image data to be displayed on the display unit 111. The memory 109 has a storage capacity sufficient to store a predetermined number of still images, moving images for a predetermined time, and audio.

Further, the memory 109 also serves as a memory (video memory) for displaying an image. The D / A converter 110 converts the image display data stored in the memory 109 into an analog signal and supplies it to the display unit 111. In this way, the display image data written in the memory 109 is displayed by the display unit 111 via the D / A converter 110.

The display unit 111 displays on a display such as an LCD according to the analog signal from the D / A converter 110. The digital signal once A / D converted by the A / D converter 107 and stored in the memory 109 is analog-converted by the D / A converter 110 and sequentially transferred to the display unit 111 for display as an electronic viewfinder. It functions and can display through images. Hereinafter referred to as a live view image.

The non-volatile memory 114 is a memory that can be electrically erased and recorded, and for example, EEPROM or the like is used. The non-volatile memory 114 stores constants, programs, and the like for the operation of the system control unit 101. The program referred to here is a program for executing various flowcharts described later in the present embodiment.

The system control unit 101 controls the entire digital camera 100. By executing the program recorded in the non-volatile memory 114 described above, each process of the present embodiment described later is realized. The system memory 112 is a system memory, and RAM is used. In the system memory 112, constants and variables for the operation of the system control unit 101, a program read from the non-volatile memory 114, and the like are expanded. The system control unit also controls the display by controlling the memory 109, the D / A converter 110, the display unit 111, and the like. The system timer 113 is a time measuring unit that measures the time used for various controls and the time of the built-in clock.

The shutter button 115, the mode switching dial 118, the power button 119, and the operation unit 200 are operation means for inputting various operation instructions to the system control unit 101 (the system control unit 101 has been operated on the operation unit 200). It can be detected).

The mode switching dial 118 switches the operation mode of the system control unit 101 to a still image recording mode, a moving image recording mode, a playback mode, and a detailed mode included in each operation mode.

The first shutter switch 116 is turned on by a so-called half-press (shooting preparation instruction) during the operation of the shutter button 115 provided on the digital camera 100, and the first shutter switch signal SW1 is generated. The first shutter switch signal SW1 starts operations such as AF (autofocus) processing, AE (autoexposure) processing, AWB (auto white balance) processing, and EF (flash pre-flash) processing.

The second shutter switch 117 is turned on when the operation of the shutter button 115 is completed, that is, when the shutter button 115 is fully pressed (shooting instruction), and the second shutter switch signal SW2 is generated. The system control unit 101 starts a series of shooting processes from reading the signal from the imaging unit 106 to writing the image data to the recording medium 124 by the second shutter switch signal SW2.

The power supply control unit 121 is composed of a battery detection circuit, a DC-DC converter, a switch circuit for switching a block to be energized, and the like, and detects the state of the power button 119, whether or not a battery is installed, the type of battery, and the remaining battery level. .. Further, the power supply control unit 121 controls the DC-DC converter based on the detection result and the instruction of the system control unit 101, and supplies a necessary voltage to each unit including the recording medium 124 for a necessary period.

The power supply unit 122 includes a primary battery such as an alkaline battery or a lithium battery, a secondary battery such as a NiCd battery, a NiMH battery, or a Li battery, an AC adapter, or the like. In this embodiment, a case where a secondary battery is used for the power supply unit (hereinafter referred to as a battery) will be described.

The recording medium I / F 123 is an interface with a recording medium 124 such as a memory card or a hard disk. The recording medium 124 is a recording medium such as a memory card for recording a captured image, and is composed of a semiconductor memory, a magnetic disk, or the like.

Each operation member of the operation unit 200 is assigned a function as appropriate for each scene by selecting and operating various function icons displayed on the display unit 111, and acts as various function buttons. The function buttons include, for example, an end button, a back button, an image feed button, a jump button, a narrowing down button, an attribute change button, and the like. The operation unit 200 includes a touch panel 200a, a menu button 201, a multi-controller 208, a cross button 202, and a SET button 203. Further, the operation unit 200 includes a controller wheel 204, an electronic dial 205, an INFORMATION button 206, and the like. The cross button 202 consists of an up key 202a in the upward direction, a down key 202b in the downward direction, a left key 202c in the left direction, and a right key 202d in the right direction. Can be used for. For example, when the menu button 201 shown in FIG. 1B is pressed, various settable menu screens are displayed on the display unit 111. The user can intuitively make various settings by using the menu screen displayed on the display unit 111 and the cross-shaped button 202 or the SET button 203 having buttons in four directions of up, down, left, and right. The controller wheel 204, the electronic dial 205, and the multi-controller 208 are rotationally operable operating members included in the operating unit 200, and are used when instructing a selection item together with a direction button. When the controller wheel 204 or the electronic dial 205 is rotated, an electric pulse signal is generated according to the amount of operation, and the system control unit 101 controls each part of the digital camera 100 based on the pulse signal. From this pulse signal, it is possible to determine the angle at which the controller wheel 204 and the electronic dial 205 are rotated, the number of rotations, and the like. The controller wheel 204 and the electronic dial 205 may be any operating member that can detect the rotation operation. For example, the controller wheel 204 or the electronic dial 205 itself may be a dial operation member that rotates in response to a user's rotation operation to generate a pulse signal. Further, the operation member including the touch sensor may be one that does not rotate the controller wheel 204 itself and detects the rotational movement of the user's finger on the controller wheel 204 (so-called touch wheel). Like the cross key 202, the multi-controller 208 is a controller capable of instructing in the right direction, the left direction, the up direction, and the down direction, and the direction can be instructed by tilting the lever in each direction. The INFORMATION button 206 is a button for switching the amount of information displayed on the display unit 111. Each time the INFORMATION button 206 is pressed, the amount of information can be switched in the order of standard, detailed, and hidden.

The battery 122 and the recording medium 124 can be inserted into the digital camera 100 from the bottom surface of the digital camera, and can be covered with a cover 207 that can be opened and closed.

As one of the operation units 200, there is a touch panel 200a capable of detecting contact with the display unit 111. The touch panel 200a and the display unit 111 can be integrally configured. For example, the touch panel 200a is configured so that the light transmittance does not interfere with the display of the display unit 111, and is attached to the upper layer of the display surface of the display unit 111. Then, the input coordinates on the touch panel 200a are associated with the display coordinates on the display unit 111 (on the display surface). As a result, it is possible to configure the GUI as if the user can directly operate the screen displayed on the display unit 111. The system control unit 101 can detect (touch detect) the following operations on the touch panel.
-A finger or pen that was not touching the touch panel has newly touched the touch panel. That is, the start of touch (hereinafter referred to as touch-down).
-The touch panel is in a state of being touched with a finger or a pen (hereinafter referred to as touch-on).
-Move while touching the touch panel with a finger or pen (hereinafter referred to as Touch-Move).
-Release the finger or pen that was touching the touch panel. That is, the end of touch (hereinafter referred to as touch-up (Touch-Up)).
-A state in which nothing is touched on the touch panel (hereinafter referred to as touch-off).
-After touching down on the touch panel, touching up should be done in a short time. Touch operation that repels the touch panel (hereinafter referred to as Tap).

These operations and the position coordinates of the finger or pen touching the touch panel are notified to the system control unit 101 through the internal bus, and the system control unit 101 performs what kind of operation on the touch panel based on the notified information. Determine if it was done. Regarding the touch move, the moving direction of the finger or pen moving on the touch panel can also be determined for each vertical component and horizontal component on the touch panel based on the change in the position coordinates. Further, it is assumed that a stroke is drawn when the touch panel is touched up from the touchdown through a certain touch move. The operation of drawing a stroke quickly is called flicking. Flicking is an operation of quickly moving a finger on the touch panel by a certain distance and then releasing it as it is, in other words, an operation of quickly tracing the touch panel as if flicking it with a finger. It can be determined that the flick has been performed when it is detected that the touch move is performed at a predetermined speed or more over a predetermined distance and the touch-up is detected as it is. In addition, if it is detected that the vehicle has moved more than a predetermined distance at a speed lower than the predetermined speed, it is determined that the drag has been performed. It is also possible to detect an operation of moving the touch panel with a finger or a pen to enter a specific area (hereinafter referred to as move-in) and an operation of moving out of the specific area (hereinafter referred to as move-out). Further, a touch operation for shortening the distance between the two touch points, that is, an operation for pinching the displayed image is pinch-in, and is used as an operation for reducing the image or increasing the number of displayed images. A touch operation that widens the distance between two touch points, that is, an operation that widens the displayed image is a pinch-out, and is used as an operation of enlarging the image or reducing the number of displayed images. As the touch panel, any of various types of touch panels such as a resistive film method, a capacitance method, a surface acoustic wave method, an infrared method, an electromagnetic induction method, an image recognition method, and an optical sensor method may be used. ..

If the displayed range of items 609-614 is tapped even in the image, S310 is set to No. If it is determined that the tap operation has been performed, the process proceeds to S311. If not, the process proceeds to S313.

In S311 the system control unit 101 displays an error message on the display unit 111. The guide 617 of FIG. 6F is an example of the error message displayed in S311 and shows that the direction of the virtual light source can be changed by the touch move. In the present embodiment, the direction of the virtual light source can be changed by the touch move operation in order to distinguish between the operation of selecting the item displayed on the setting screen and the operation of changing the direction of the virtual light source. Therefore, when it is determined that the area on the image where the item 609-614 is not displayed has been tapped, an error message is displayed. By not accepting the change of the direction of the virtual light source by tap operation, the touch position of the user who tried to select the item shifts from the position of the item, and the direction of the virtual light source is changed unintentionally. Can be prevented.

In S312, the system control unit 101 determines whether or not the item 618 indicating OK displayed together with the guide 617 is selected. When the user selects the item 618, the user confirms the guide 617 and proceeds to S313.

In S313, the system control unit 101 determines whether or not the touch move has been detected. The area that accepts the touch move is the entire range of the setting screen in this embodiment. If it is determined that the touch move is detected, the process proceeds to S314, and if not, the process proceeds to S315.

In S314, the system control unit 101 executes the touch move process. The touch move process will be described with reference to FIG.

In S315, the system control unit 101 determines whether or not the operation of the rotating member has been detected. The rotating member operation is a rotating operation on the electronic dial 205 or the controller wheel 204. If an operation on the rotating member is detected, the process proceeds to S316, and if not, the process proceeds to 317.

In S316, the system control unit 101 executes the rotating member operation process. The rotating member operation process will be described with reference to FIG.

In S317, the system control unit 101 determines whether or not the cross-shaped button operation is detected. If any of the keys of the cross-shaped button 202 is operated, the determination in S317 is Yes, and the process proceeds to S318. If not, the process proceeds to S319.

In S318, the system control unit 101 executes the cross-shaped button processing. The cross-shaped button processing will be described with reference to FIG.

In S319, the system control unit 101 determines whether or not an operation for instructing the reset of editing of the virtual light source has been performed. That is, it is determined whether or not the item 612 is selected. If it is determined that the reset is instructed, the process proceeds to S320, and if not, the process proceeds to S322.

In S320, the system control unit 101 returns the direction of the virtual light source indicated by the item 615 to the center. Item 615 indicates the direction of the virtual light source. When the direction of the virtual light source is changed, the item 615a moves from the center as shown in the item 615 of FIG. 6 (h), but returns to the center position again in S320.

In S321, the system control unit 101 returns the editing of the virtual light source to the initial setting. In other words, even if the intensity or range of the virtual light source is changed, the default settings are restored.

In S322, the system control unit 101 determines whether or not an instruction to save the edit has been given. That is, it is determined whether or not the item 613 indicating OK is selected. If it is determined in S322 that the instruction to save the edit has been given, the process proceeds to S323, and if not, the process proceeds to S324.

In S323, the system control unit 101 saves the editing information of the virtual light source and records it on the recording medium 124.

In S324, the system control unit 101 determines whether or not an instruction to end the display of the edit screen has been given. That is, it is determined whether or not the item 614 is selected. If it is determined that the instruction to end the display of the edit screen has been given, the process returns to S221 in FIG. 2, and if not, the process returns to S302.

Next, the face selection process in the present embodiment will be described with reference to FIG. This process is realized by expanding the program recorded in the non-volatile memory 114 to the system memory 112 and executing it by the system control unit 101. The process of FIG. 4 starts when the process proceeds to S305 of FIG.

In S401, the system control unit 101 determines whether or not a plurality of faces are detected based on the face information acquired in S211 of FIG. If it is determined that a plurality of faces are detected, the process proceeds to S402, and if not, the process of FIG. 4 ends.

In S402, the system control unit 101 displays the face selection screen on the display unit 111. On the face selection screen, the user can switch the central subject (face) for changing the irradiation direction of the virtual light source. The switchable face is determined based on the face information recorded together with the image. For example, if the face is too small or blurred, there is a high possibility that even if there is a subject in the image, it will not be detected as a face, and that face cannot be selected on the face selection screen. FIG. 6 (i) shows an example of the face selection screen. Item 616 is an item (face frame) indicating the currently selected face. A mark 620 indicating an arrow is displayed next to the item 616, indicating that the item 616 can be moved. Item 619 is an item (face frame) indicating a selectable face.

In the present embodiment, the screen that accepts the operation of selecting a face and the screen that changes the irradiation direction (the screen that changes the degree of effect) are switched, and when one operation can be accepted, the other operation is not accepted. I am trying to do it. As a result, the item 619 indicating the face that can be selected when the irradiation direction is changed is not displayed, so that the user can easily check how the effect is applied, and the face that is selected and the face that can be selected on the selection screen can be selected. You can check.

Further, when the user tries to select a face by a touch operation, the possibility that the touch position moves and is changed to an unintended irradiation direction can be reduced. Further, when the user is trying to change the irradiation direction by touch operation, it is possible to reduce the possibility that the face to be selected is unintentionally changed by touching the face unintentionally. However, when the face is selected or the irradiation direction is changed by operating the operation member instead of the touch operation, the screen for accepting the face selection and the screen for changing the irradiation direction may be the same.

In S403, the system control unit 101 determines whether or not the operation member whose face to be selected can be changed has been operated. The face to be selected can be selected by moving the multi-controller 208 left or right, or by moving the multi-controller 208 up or down when the selectable face position is above or below the currently selected face. .. Furthermore, the face to be selected can be changed by rotating the controller wheel 204. If it is determined that the face to be selected has been operated on the changeable operating member, the process proceeds to S404, and if not, the process proceeds to S406.

In S404, the system control unit 101 performs a process of changing the selected face and a process of updating the display of the item 616 indicating the selected face. FIG. 6 (j) shows a display example when the face selected from FIG. 6 (i) is changed. In FIG. 6 (i), the face on which the item 616 is displayed is reflected from the subject on the right side to the subject on the left side.

In S405, the system control unit 101 performs image processing that irradiates a virtual light source centering on the face selected in S404. When the face to be selected is changed, the image processing is also performed in S405 by inheriting the irradiation direction and brightness parameters set in the face selected immediately before. However, image processing may be performed by irradiating a virtual light source from the initial direction each time the face is switched. When the irradiation direction set for the face selected immediately before is inherited as it is, for example, when the right side of the entire image is dark, the user wants to shine light from the right direction, but which user is the center of the virtual light source It is effective when you want to compare whether it is most appropriate to irradiate. The user does not have to go back to the screen to change the irradiation direction of the original virtual light source and change the irradiation direction, just switch the face on the face selection screen, and compare the specific effects of the selected face. Can be done. At this time, the timing for reflecting the effect of the virtual light source on the selected face may be immediately after the change or after a certain period of time has elapsed.

In S406, the system control unit 101 determines whether or not a touch operation has been performed on the selectable face. If it is determined that the selectable face, that is, the item 619 has a touch operation on the selected face, the process proceeds to S407, and if not, the process proceeds to S409.

The processing of S407 and S408 is the same processing as the processing of S404 and S405.

In S409, the system control unit 101 determines whether or not an operation of returning to the setting screen from the face selection screen has been performed. This can be done by selecting item 620 from the face selection screen to the setting screen. If it is determined to be Yes in S409, the process of FIG. 4 is terminated, and if not, the process returns to S403.

Next, the touch move process in the present embodiment will be described with reference to FIG. This process is realized by expanding the program recorded in the non-volatile memory 114 to the system memory 112 and executing it by the system control unit 101. The process of FIG. 5 starts when the process proceeds to S314 of FIG.

In S501, the system control unit 101 hides the item 616 indicating the selected face. FIG. 6 (h) shows an example of the setting screen when the touch move process is performed, and when it is detected that the touch move is started from the state of the setting screen shown in FIG. 6 (e), the item is displayed. The state shown in FIG. 6 (h) is such that 616 is hidden. By displaying the item 616, it is easy for the user to know which face the selected face is, and the user can easily understand the central face that is currently illuminated by the virtual light source. On the other hand, if the item remains displayed around the face, it becomes difficult to understand how the effect of irradiation has changed. Therefore, the touch move is started, and the item 616 is hidden in response to the user changing the irradiation direction (beginning to change the degree of effect). This makes it easier for the user to grasp the effect of the virtual light source, and can recognize the selected subject (because the item 616 is displayed until just before changing the effect of the virtual light source). Even if the item 616 is not hidden, the area around the selected face and the item overlap may be reduced, or the display of the item 616 may be lightened.

In S502, the system control unit 101 detects (vectors) the direction and length of the touch move detected in S313.

Here, the display of the irradiation direction of the virtual light source and the display of the item indicating the irradiation direction will be described with reference to FIG. 7.

The virtual light source can move the surface area 701 of the hemisphere covering the front surface of the face around the selected face. Since the virtual light source always faces the center of the face, the direction of the light source can be freely changed by moving the surface area of the hemisphere. The item 615 displayed on the screen represents a state in which the surface area 701 of the hemisphere is projected onto a plane, the movable range 707 of the virtual light source, the index 708 indicating the current position of the virtual light source (item 615a in FIG. 6), and the hemisphere. It is composed of a central index 709 indicating the apex of the surface region of. Typical positions of the virtual light source are indicated by 702 to 706 (positions A to E in order). These positions are represented on the items indicating the irradiation direction as shown in 710 to 714, respectively. If the parameters of the brightness and the irradiation range other than the irradiation direction are constant, the intensity of the virtual light source applied to the selected face is the same regardless of the position of the item 615a. That is, just because the index 708 approaches the central index 709 does not mean that the virtual light source approaches the selected face or the light becomes stronger. Item 615 (possible range 707) is a two-dimensional representation of a hemisphere in which a virtual light source can move. The irradiation direction of the virtual light source, that is, the position of the virtual light source on the surface region of the hemisphere can be changed by using the touch panel 200a or the operation member 120. Further, since the index on the item indicating the irradiation direction also moves according to the change in the direction of the virtual light source, the operator can change the irradiation direction of the virtual light source as if moving the item 615a on the setting screen.

When the item 615a moves on the line of the item 615 on the setting screen, the item 615a cannot move further to the outside. Therefore, for example, when the item 615a is moved to the right end of the item 615 and the user makes a touch move diagonally upward to the right, the item 615a is moved only upward (the vector portion of the upward touch move). ), Move along the circumference.

The above is the description of FIG. 7.

In S503, the system control unit 101 calculates the amount of movement of the virtual light source, that is, the angle of movement in the hemisphere, based on the touch move vector detected in S502.

In S504, the system control unit 101 calculates the movement amount and the moved position calculated in S503 from the current position of the virtual light source.

In S505, the system control unit 101 updates the display of the item 615 based on the position calculated in S504.

In S506, the system control unit 101 performs image processing in which the direction of irradiating the virtual light source is changed based on the position calculated in S514. As described above, the irradiation direction of the virtual light source is changed from the setting at the start of the touch move according to the amount and direction of the touch move regardless of the touch start position of the user. That is, when irradiating the virtual light source from the right direction, the irradiation direction can be changed by touch-moving the left side of the setting screen, so that the finger of the user performing the touch operation touches the selected face. It does not take, and the visibility does not decrease. In addition, the item indicating the virtual light source is not superimposed on the image and displayed on the setting screen, but the item 615 showing the direction of the virtual light source with respect to the selected subject is displayed. You can see the irradiation direction of. When an item indicating a virtual light source is superimposed on an image and displayed on the setting screen, the item is displayed superimposed on the selected face when the irradiation range of the virtual light source is set narrowly, or at a position very close to it. there is a possibility. Therefore, by displaying the item 615 as described in the present embodiment, the user can perform the irradiation direction change operation by touch operation with good visibility regardless of the user's setting. Further, in the face selection described with reference to FIG. 4, the subject at the touch position on the image is selected (absolute position designation), but the relative position is specified when the irradiation direction is changed. When selecting a subject to apply an effect, it is easier for the user to understand by directly touching the target to be selected on the screen, but it is easier to understand the effect on the subject if the effect of the image can be changed relatively.

In S507, the system control unit 101 determines whether or not the touch move has stopped. If it is determined that the touch move has stopped, the process proceeds to S508, and if not, the process proceeds to S502.

In S508, the system control unit 101 starts measuring the display count T. The display count T is a time for counting the time until the item 615 indicating the selected face hidden in S501 is displayed again. In this embodiment after the touch move is stopped, the item 615 is displayed again after 2 seconds have passed without the touch move being started.

In S509, the system control unit 101 determines whether or not the display count T has elapsed for 2 seconds. If it is determined that the display count T has elapsed for 2 seconds, the process proceeds to S510 and the item 615 is displayed again. If it is determined that the display count T has not elapsed for 2 seconds, the process proceeds to S511.

In S511, the system control unit 101 determines whether or not the touch move has been started again, and if it is determined that the touch move has started again, the process proceeds to S502, and if not, the process proceeds to S509.

Here, the operation of changing the irradiation direction of the virtual light source by the touch move operation in the present embodiment will be described with reference to FIG.

As described above, the irradiation direction is changed by the touch operation relative to the direction and length of the touch move. In order for the operator to move the virtual light source to the desired position (that is, the position indicating the irradiation direction), as shown in FIG. 8A, the touch move (drag) is repeated several times in the same direction to move the position of the item 615a. Try to reach the desired position. Further, when the item 615a reaches the outer circumference of the hemispherical region described with reference to FIG. 7 and the touch move is continued toward the region beyond the hemisphere, the index corresponds to the touch move direction as shown in FIG. 8 (b). Moves along the outer circumference. That is, in FIG. 8A, assuming that the vector of the user's touch move is X0, the item 615a moves X'0 corresponding to X0. As a result of the movement in FIG. 8A, when the user makes a further touch move in the upper right direction from the state where the item 615a is located on the circumference of the item 615, the result is as follows. Let X1 be the vector of the touch move in FIG. 8B, and let x1 and y1 be the movement amounts of the x-axis and y-axis, respectively. At this time, the item 615a moves along the circumference of the item 615 so as to move in the x-axis direction by the amount of movement of x2 according to x1.

Further, since the position of the item 615a moves in a relative relationship with the touch move operation, the index can be moved in any direction regardless of the position of the touch move operation on the setting screen. In particular, operability is improved in devices having a small screen such as a digital camera 100 and a smartphone.

On the other hand, the method of specifying the position on the screen as an absolute position has an advantage that the position can be easily recognized intuitively. In the present embodiment, the selectable face may be the edge of the screen. Therefore, if the irradiation direction of the virtual light source can be relatively changed, the selected face is the right edge of the screen as shown in FIG. 8C. Easy to operate even when you are in the office.

Next, the rotating member operation process in the present embodiment will be described with reference to FIG. This process is realized by expanding the program recorded in the non-volatile memory 114 to the system memory 112 and executing it by the system control unit 101. The process of FIG. 9 starts when the process proceeds to S316 of FIG.

In S901, the system control unit 101 hides the item 616 indicating the selected face as in S501 of FIG.

In S902, the system control unit 101 determines whether or not the controller wheel 204 has been rotated clockwise. If the right rotation operation is accepted, the process proceeds to S903, and if not, the process proceeds to S907.

In S903, the system control unit 101 determines whether the item indicating the irradiation direction (that is, the item 615a) is on the curve of the movable range (on the circumference of the item 615). For example, the positions shown in B, C, D, and E in FIG. 7 indicate that they are on a curve. If it is on a curve, proceed to S904, otherwise proceed to S905. In addition, instead of determining by the position of the item 615a, it may be determined whether or not the currently set irradiation direction is the end of the irradiation range (the position of the boundary).

In S904, the system control unit 101 determines whether the item 615a is within the lower half of the entire movable range. The region of the lower half of the entire movable range referred to here refers to the region shown by the region 1111 in FIG. 11 (a). If it is in the lower half area, proceed to S918, otherwise proceed to S905.

In the present embodiment, when the rotating member is operated, the item 615a is prevented from moving if it is on the curve in the movement instruction direction of the movable range. For example, suppose that when the item 615a is located at the position F in FIG. 11-2, the controller wheel 204 is moved to the position G in FIG. 11-2 in response to the clockwise rotation. The clockwise rotation of the controller wheel 204 is a downward movement instruction. In this case, the controller wheel 204 should have been rotated clockwise, but the item 615a moves counterclockwise (1123) on the curve (that is, on the circumference) because it moves downward. Since the movement from 1122 to 1124 is a movement in the counterclockwise direction as a movement on the circumference, the movement direction of the item 615a is opposite to the rotation direction of the user's operating member, but the item 615a is not moved. By doing so, the user does not feel uncomfortable. That is, the operability of the user becomes intuitive.

In S905, the system control unit 101 performs a process of moving the item 615a down one memory. For example, this movement indicates that the item 615a moves downward from the position B in FIG. 7 as in the position movement of B'in FIG. 11 (b). That is, when the controller wheel 204 is rotated clockwise, it can be seen that the item 615a moves downward (that is, the positive direction of the Y component in FIG. 11E).

In S906, the system control unit 101 performs image processing in which the direction of irradiating the virtual light source is changed according to the user operation. When the controller wheel 204 is rotated clockwise, the item 615a moves downward and the irradiation direction moves downward.

In S907, the system control unit 101 determines whether or not the controller wheel 204 has been rotated counterclockwise. If the counterclockwise operation is accepted, the process proceeds to S908, and if not, the process proceeds to S921.

In S908, the system control unit 101 determines whether the item 615a is on the curve of the movable range (on the circumference of the item 615). If it is on a curve, proceed to S909, otherwise proceed to S910.

In S909, the system control unit 101 determines whether the item 615a is within the upper half of the entire movable range. The region of the upper half of the entire movable range referred to here refers to the region shown by the region 1112 in FIG. 11 (a). If it is in the upper half area, proceed to S918, otherwise proceed to S910.

In S910, the system control unit 101 performs a process of moving the item 615a onto one memory.

In S911, the system control unit 101 determines whether or not the electronic dial 205 has been rotated clockwise. If the right rotation operation is accepted, the process proceeds to S912, otherwise the process proceeds to S915.

In S912, the system control unit 101 determines whether the item 615a is on the curve of the movable range (on the circumference of the item 615). If it is on a curve, proceed to S913, otherwise proceed to S914.

In S913, the system control unit 101 determines whether the item 615a is within the area of the right half of the entire movable range. The region on the right half of the entire movable range referred to here refers to the region shown by the region 1113 in FIG. 11 (a). If it is in the right half area, proceed to S918, otherwise proceed to S914.

In S914, the system control unit 101 performs a process of moving the item 615a to the right by one memory.

In S915, the system control unit 101 determines whether the item 615a is on the curve of the movable range (on the circumference of the item 615). If it is on a curve, proceed to S916, otherwise proceed to S917. Since No was determined in S911, the processing of S915 to S917 is the processing when the electronic dial 205 is rotated counterclockwise.

In S916, the system control unit 101 determines whether the item 615a is within the left half of the entire movable range. The left half region of the entire movable range referred to here refers to the region shown by the region 1114 in FIG. 11 (a). If it is in the left half area, proceed to S918, otherwise proceed to S917.

In S917, the system control unit 101 performs a process of moving the item 615a to the left by one memory. In the present embodiment, the item 615a is moved by one memory in a predetermined amount of rotation (one pulse) of the rotating member, but this one memory is an angle such as 5 degrees or 10 degrees in the irradiation direction. The amount of movement corresponding to is shown.

In S918, the system control unit 101 starts measuring the display count T in the same manner as in S508 of FIG.

In S919, the system control unit 101 determines whether or not the display count T has elapsed for 2 seconds, as in S509 of FIG. If it is determined that the display count T has elapsed for 2 seconds, the process proceeds to S920 and the item 615 is displayed again. If it is determined that the display count T has not elapsed for 2 seconds, the process proceeds to S921.

In S921, the system control unit 101 determines whether or not the rotation member operation is detected again, and if it is detected, proceeds to S902, and if not, proceeds to S919.

Next, the cross-shaped button operation process in the present embodiment will be described with reference to FIG. This process is realized by expanding the program recorded in the non-volatile memory 114 to the system memory 112 and executing it by the system control unit 101. The process of FIG. 10 starts when the process proceeds to S318 of FIG.

In S1000, the system control unit 101 hides the item 616 indicating the selected face, as in S501 of FIG. Whether it is the touch operation described with reference to FIG. 5 or the operation member using the cross-shaped button or the rotating member, the face being selected is shown according to the instruction to change the irradiation direction of the virtual light source. Items are hidden so that the effect of irradiation is easy to understand.

In S1001, the system control unit 101 determines whether or not the lower key 202b of the cross button 202 is pressed. If it is determined that the down key 202b has been pressed, the process proceeds to S1002, and if not, the process proceeds to S1007.

In S1002, the system control unit 101 determines whether the item indicating the irradiation direction (that is, the item 615a) is on the curve of the movable range (on the circumference of the item 615), similarly to S903 in FIG. If it is on a curve, proceed to S1003, otherwise proceed to S1005.

In S1003, the system control unit 101 determines whether the item 615a is within the lower half of the entire movable range, as in S904 of FIG. If it is in the lower half area, proceed to S1004, otherwise proceed to S1005.

In S1004, the system control unit 101 determines whether or not the item 615a is at the bottom of the movable range (on the curve). That is, it is determined whether the item 615a is in a position where it cannot move downward any more. This is the state of D in FIG. If it is determined that the item 615a is at the bottom of the movable range, the process proceeds to S1025, and if not, the process proceeds to S1005.

In S1005, the system control unit 101 moves the item 615a downward by one memory along the curve of the movable range. That is, the movement distance of the item 615a is larger than one memory, but the item 615a moves on the curve so that the coordinates change by one memory in the plus direction of the y-axis of FIG. 11 (e).

In S1006, the system control unit 101 performs a process of moving the item 615a down one memory in the same manner as in S905 of FIG.

In S1007, the system control unit 101 performs image processing in which the direction of irradiating the virtual light source is changed according to the user operation, as in S906 of FIG.

In S1008, the system control unit 101 determines whether or not the upper key 202a of the cross button 202 is pressed. If it is determined that the upper key 202a has been pressed, the process proceeds to S1009, and if not, the process proceeds to S1014.

In S1009, the system control unit 101 determines whether the item indicating the irradiation direction (that is, the item 615a) is on the curve of the movable range (on the circumference of the item 615), similarly to S903 in FIG. If it is on a curve, proceed to S1010, otherwise proceed to S1013.

In S1010, the system control unit 101 determines whether the item 615a is within the upper half of the entire movable range, as in S909 of FIG. If it is in the upper half area, the process proceeds to S1011. If not, the process proceeds to S1013.

In S1011, the system control unit 101 determines whether or not the item 615a is at the top of the movable range (on the curve). That is, it is determined whether the item 615a is in a position where it cannot move upward any more. This is the state B in FIG. If it is determined that the item 615a is at the top of the movable range, the process proceeds to S1025, and if not, the process proceeds to S1012.

In S1012, the system control unit 101 moves the item 615a along the curve of the movable range so as to move upward by one memory. That is, the movement distance of the item 615a is larger than one memory, but the item 615a moves on the curve so that the coordinates change by one memory in the minus direction of the y-axis in FIG. 11 (e).

In S1013, the system control unit 101 performs a process of moving the item 615a onto one memory.

In S1014, the system control unit 101 determines whether or not the right key 202d of the cross button 202 is pressed. If it is determined that the right key 202d is pressed, the process proceeds to S1015, and if not, the process proceeds to S1020.

In S1015, the system control unit 101 determines whether the item indicating the irradiation direction (that is, the item 615a) is on the curve of the movable range (on the circumference of the item 615), similarly to S903 in FIG. If it is on a curve, proceed to S1016, otherwise proceed to S1019.

In S1016, the system control unit 101 determines whether the item 615a is within the right half of the entire movable range, as in S913 in FIG. If it is in the right half area, proceed to S1017, otherwise proceed to S1019.

In S1017, the system control unit 101 determines whether or not the item 615a is in the rightmost portion (right end) of the movable range (on the curve). That is, it is determined whether the item 615a is in a position where it cannot move to the right any more. This is the state C in FIG. If it is determined that the item 615a is in the rightmost part of the movable range, the process proceeds to S1025, and if not, the process proceeds to S1018.

In S1018, the system control unit 101 moves the item 615a along the curve of the movable range so as to be one memory to the right. That is, the movement distance of the item 615a is larger than one memory, but the item 615a moves on the curve so that the coordinates change by one memory in the plus direction of the x-axis of FIG. 11 (e).

In S1019, the system control unit 101 performs a process of moving the item 615a to the right by one memory, similarly to S914 of FIG.

In S1020, the system control unit 101 determines whether the item indicating the irradiation direction (that is, the item 615a) is on the curve of the movable range (on the circumference of the item 615), similarly to S903 in FIG. If it is on a curve, proceed to S1021, otherwise proceed to S1024.

In S1021, the system control unit 101 determines whether the item 615a is within the left half region of the entire movable range, as in S916 of FIG. If it is in the left half area, proceed to S1022, otherwise proceed to S1024.

In S1022, the system control unit 101 determines whether or not the item 615a is in the leftmost portion (left end) of the movable range (on the curve). That is, it is determined whether the item 615a is in a position where it cannot move to the left any more. This is the state of E in FIG. If it is determined that the item 615a is in the leftmost part of the movable range, the process proceeds to S1025, and if not, the process proceeds to S1023.

In S1023, the system control unit 101 moves the item 615a along the curve of the movable range so as to move the item 615a to the left by one memory. That is, the movement distance of the item 615a is larger than one memory, but the item 615a moves on the curve so that the coordinates change by one memory in the minus direction of the x-axis of FIG. 11 (e).

In S1024, the system control unit 101 performs a process of moving the item 615a to the left by one memory, as in S917 of FIG.

S1025 to S1027 are the same processes as S918 to S920 of FIG.

In S1028, the system control unit 101 determines whether or not the cross-shaped button operation is detected again, and if it is detected, proceeds to S1001, and if not, proceeds to S1026.

The movement of the item 615a when the cross button 202 (multi-controller 208) and the rotation operation member are operated will be described with reference to FIGS. 11 (f) to 11 (i). 11 (f) to 11 (i) show the state of the item 615a before and after the movement. When the lower key 202b of the cross button 202 (downward of the multi-controller 208) is operated, the item 615a moves as shown in FIG. 11 (f). At this time, even when the controller wheel 204 is rotated clockwise, the item 615a moves as shown in FIG. 11 (f). On the other hand, as shown in FIG. 11 (g), when the item 615a before movement is on the curve of the movable range, when the lower key 202b of the cross button 202 is operated, the item 615a moves along the curve. ..

Similarly, when the right key 202d of the cross button 202 is operated, the item 615a moves as shown in FIG. 11 (h). At this time, even if the electronic dial 205 is rotated clockwise, the item 615a moves as shown in FIG. 11 (h). When the item 615a is on the curve of the movable range, the item 615a moves along the curve as shown in FIG. 11 (i).

When the controller wheel 204 or the electronic dial 205 is rotated, the item 615a does not move when it is on the curve (boundary) of the movable range.

As described above, in the present embodiment, the operation of the cross-shaped button 202 or the multi-controller 208 allows the item 615a to move along the curve. Since it is not a rotating member, the direction of instruction for movement and the direction of operation are the same. Therefore, unless the item 615a moves in the direction opposite to the operation direction, even if the item 615a does not move only in the operation direction, it is unlikely to give a sense of discomfort to the user as long as it moves in the operation direction. In other words, when instructing to the right, if the item 615a does not move in the minus direction of the X axis, even if it moves slightly in the Y axis direction, if it moves even in the plus direction of the X axis, the user can use the operation direction. It can be seen that the moving directions of the item 615a are correct. As long as there is an operation direction and a movement direction of the item 615a, the user can know that the item 615a is moving based on the operation direction, so that the user can perform an intuitive operation. On the other hand, although the instruction is given to the right, the item 615a moves based on the operation direction when it does not move in the plus direction of the X axis but moves only in the Y axis direction or moves in the minus direction of the X axis. The user is likely to feel that they are not. In this way, by changing the movement process of the item 615a between the rotation operation member and the operation member whose operation direction and movement instruction direction are the same, the user can operate any of the operation members. It can be operated high.

The cross-shaped button operation process is not limited to the cross-shaped button, and the same process may be performed on a member such as a joystick that can be operated in a plurality of component directions.

Further, in this embodiment, only the rotating members of the controller wheel 204 and the electronic dial 205 are described. Not limited to this, all the rotating members arranged at positions where the display surface of the indicator and the rotation axis are orthogonal to each other are subjected to the above processing (so that the rotating member is not moved in the curved direction even if the rotating member is operated on the curve). You may try to do). By controlling in this way, there is an effect that the user can be provided with a comfortable operation.

The controller wheel 204 and the electronic dial 205 can each be instructed to move along one axis, and the Y-axis direction, which is the moving direction of the controller wheel 204, is orthogonal to the X-axis, which is the moving direction of the electronic dial 205. .. Therefore, if the user moves in the X-axis direction but also in the Y-axis direction, which is the direction in which the other operating member can move, the user cannot know which operating member moves along which direction. There is a possibility that it will end up. On the other hand, when it is possible to instruct movement along two axes with one operating member such as the cross key 202 or the multi-controller 208, it is also possible to instruct movement in the X-axis direction and the Y-axis direction within the same operating member. Is. Therefore, it is unlikely that the user will feel uncomfortable as long as the vehicle is moving at least in the indicated direction. In this way, the operability of the user is improved by changing the movement control depending on whether the operating member can instruct the movement of one axis or two axes. If the region is formed (enclosed) along a different axis from the X-axis, which can be instructed to move by operating the operating member, and the Y-axis, which is orthogonal to the X-axis, the movement is not in a circle. However, the processes of FIGS. 9 and 10 are effective. That is, a rhombus or an ellipse is also effective.

From the above, one effect of the present embodiment is that when the irradiation direction of the virtual light source is changed by the touch operation, the finger of the user who performs the touch operation does not touch the selected face, and the visibility does not deteriorate. In addition, since the item 615 that shows the direction of the virtual light source with respect to the selected subject is displayed, the current irradiation direction can be known even if the touch operation is relatively performed. Therefore, the user can perform the operation of changing the irradiation direction by touch operation with good visibility.

From the above, as one effect according to the present embodiment, the user can easily grasp the effect of the virtual light source and can recognize the selected subject.

From the above, as one effect of the present embodiment, when the irradiation direction of the virtual light source is changed by the rotation operation member, the user can perform an intuitive operation.

Next, a modified example of the detailed setting display of S301 of FIG. 3 will be described with reference to the flowchart of FIG. 12 and the screen display example of FIG. Except for the display of the detailed setting display, it is the same as the embodiment described with reference to FIGS. 1 to 11. However, in the modified example, for the sake of explanation, the item 615 is not displayed, and the virtual light source is directly superimposed on the image and displayed (virtual light source 1304), but the item 615 may be displayed.

FIG. 12 is a flowchart for explaining a modified example of the detailed setting display of the process of S301.

The system control unit 101 detects the face included in the selected image. If there are multiple faces, multiple faces are detected. (S1202)

13 (a) to 13 (e) are screen display examples when the display process of the detailed setting screen is executed.

FIG. 13A shows how the face included in the image 1300 (captured image) is detected. It shows that the face 1302 and the face 1306 were detected. Further, FIG. 13A shows a virtual light source 1304 that is displayed superimposed on the image 1300. The virtual light source 1304 is an item indicating the direction in which the light source is applied when performing a process of applying an effect such as when the light source is applied to the selected face. Further, the virtual light source 1304 can be moved at a relative position according to a user's touch operation. Alternatively, it can be moved by using the cross key 202 or the rotation operation member. The movement of the virtual light source is the same as in FIGS. 5, 9 and 10.

The system control unit 101 sets an area having a width equal to or larger than a predetermined width surrounding the detected face with respect to the detected face. (S1204)

FIG. 13B shows a state in which a region having a width equal to or larger than a predetermined width surrounding the face is set for the detected face.

The region having a width equal to or greater than a predetermined width surrounding the face is an region in which the effect does not change when the virtual light source and the face region are moved so as to be separated by a predetermined distance or more. That is, it is an area extended by a predetermined width to the area where the face is recognized, and refers to an area where the virtual light source has a certain effect on the face. An effect of a certain level or more is an effect that makes it possible to recognize that a virtual light source is applied on the display screen, and a position separated by a certain amount of effect is a predetermined width. Therefore, even if the same face is selected, the width in S1204 changes when the user changes the range of the virtual light source or changes the brightness. Since it is unlikely that the virtual light source will be placed at a remote position until the effect of image processing on the face is unknown, a predetermined width should be provided so that the image reduction ratio does not decrease and the visibility of the subject does not deteriorate. While improving the operability. In other words, when the selectable subject is in the central region of the display unit 111 (display surface), the image is displayed without being reduced, but when it is not in the central region, the image is reduced.

In the modified example, when the length from the center of the region recognized as a face to the edge of the region is 1, the predetermined width is 0.7. If the predetermined width is too small with respect to the face area, a virtual light source can be performed by touching the display on a small display unit 111 such as the digital camera 100 or when the face is located at the edge of the image. May overlap the face, making it difficult to see the effect on the face. Further, if the predetermined width is too large with respect to the face area, the reduction ratio described later becomes large, and it may be difficult to confirm the effect of the image. Therefore, if there is a width equal to or larger than the threshold value around the face, the image is not reduced.

In FIG. 13B, the area 1308 is set on the face 1302, and the area 1310 is set on the face 1306. When multiple faces are detected, an area is set for each face.

The shape of the region having a width equal to or larger than the predetermined width surrounding the face shall be a shape in consideration of the detection region of the face. FIG. 13 shows a square-shaped region because the face detection region is square, but if the face detection region is round, it may be a round-shaped region.

The system control unit 101 determines whether the area set in S1204 is within the display range of the display unit 111. When there are a plurality of areas in S1204, it is determined whether or not the plurality of areas are within the display range of the display unit 111. If it is within the display range of the display unit 111, the process proceeds to S1210, and if not, the process proceeds to S1208 (S1206).

In the example of FIG. 13B, it is determined that the area 1310 is not within the display range of the display unit 111.

When S1206 determines that the image is not within the display range of the display unit 111, the system control unit 101 reduces and displays the image so that the area set in S1204 is within the display range of the display unit 111. The reduction ratio for this is calculated (S1210). That is, the closer the face is to the edge of the display unit 111, or the larger the face, the larger the reduction ratio, and the smaller the image is displayed.

The system control unit 101 displays an image on the display unit 111 at the size of the reduction ratio calculated in S1210 (S1212).

In S1206, it has been explained that the determination is performed on all of the plurality of faces, but the determination is not limited to this, and the determination may be performed only on the selected face. If the determination is made only for the selected face, the reduction ratio becomes small and the visibility of the image becomes large. When the judgment is performed for all the faces, the display size of the image does not change even if the selected face is changed, so that the operation for image processing can be continued with the same size. Further, the reduction ratio may be constant regardless of the position and size of the subject.

FIG. 13C shows a state in which the image 1314 obtained by reducing the image 1300 is displayed with respect to the display area 1312 displayed on the display unit 111. As shown in FIG. 13B, when the area 1310 is not within the range of the display unit 111, the image is reduced and displayed. The image 1300 is reduced and the image 1314 is displayed at the reduction ratio calculated so that the area 1310 fits in the display area 1312 of the display unit 111. Since the image is reduced and displayed, the virtual light source 1304 can be arranged on the right side of the face 1306.

When it is determined in S1206 that the image is within the display range of the display unit 111, the system control unit 101 displays the image without reducing it as in S1212. (S1208). That is, even if the same image is displayed, the image is displayed larger when displayed in S1208 than when the image is displayed in S1212.

FIG. 13D shows how the face included in the image 1318 is detected. It shows that the face 1320 and the face 1322 were detected. Further, FIG. 13D shows a virtual light source 1328.

FIG. 13 (e) shows a state in which a region having a width equal to or larger than a predetermined width surrounding the detected face is set for the detected face. The area 1324 is set for the face 1320, and the area 1326 is set for the face 1322. In FIG. 13E, since both the area 1324 and the area 1326 are within the display range of the display unit 111, the image 1318 is displayed without being reduced. Since the virtual light source 1328 can be arranged on the right side of the face 1322 or in another direction without reducing the image, the user can perform a process of changing the direction of the virtual light source with good operability.

As described above, in the modified example, it is controlled whether the image is reduced and displayed or the image is displayed without being reduced according to the information calculated from the position of the face. This makes it easy to move the virtual light source even if the face is located at the edge of the screen and you want to move the virtual light source off the screen.

The image may be reduced and displayed on the condition that the face is located in the edge region (not in the center region) of the image (without considering the predetermined region of S1206), or in S1206. The judgment may be made only on the selected face. Further, regarding the operation of the virtual light source, the same effect can be obtained even when the virtual light source is moved at an absolute position according to the touch operation of the user. Moving the virtual light source to the user's touch position Even when moving in the absolute position, the user's operability is improved by reducing the image so that an area is created around the face.

Further, the target of the virtual light source is not limited to a human face, but may be a subject such as an animal, a vehicle, or a building.

Further, it can be applied to a case where two points, a selected position and a position for performing a predetermined process, are selected instead of the irradiation direction of the virtual light source. For example, if a subject in the selected position is selected at a position different from the selected position, an image effect that causes the subject to flow from a different position or an effect that stretches the subject can be obtained. It is also applicable when calling. Item 615 shows the positional relationship between the selected subject and the virtual position even when the irradiation direction of the virtual light source or a position different from the selected subject is selected in order to apply an image effect.

In the present embodiment, it has been described that the item indicating the irradiation direction of the virtual light source moves in the circle, but this is an example, and may be a rhombus or an ellipse.

In the present embodiment, the explanation has been given by irradiating a virtual light source as an example, but the description is not limited to this, and the case where editing is performed so as to change the color in the image or the arrangement or size of the subject in the image. It is also applicable to. In addition, it can be applied not only to still images but also to moving images. In the present embodiment, the description is limited to an image having depth information, but the description is not limited to this.

It should be noted that the above-mentioned various controls described as being performed by the system control unit 50 may be performed by one hardware, or the entire device may be controlled by sharing the processing among a plurality of hardware. ..
