Description

  The present invention relates to an imaging control device and an imaging device control method for capturing an image by an imaging unit in response to an operation on an operation unit.

  When shooting using a remote shooting method in which a live view display displayed on the display screen on the back of an imaging device such as a digital camera is enlarged and displayed on a display screen having a touch panel interface of a computer, and shooting is performed by remote control. There is. In remote shooting, a shooting button displayed on the display screen or a shooting operation on the shooting area is received, and a release command is communicated from the computer to the camera to perform shooting.

  Conventionally, an image pickup apparatus generally referred to as a camera is provided with a push button type release switch. The release switch is not pressed, and the push button is pushed to the movable end. It has an intermediate half-pressed state. In the half-pressed state of the release switch (hereinafter referred to as SW1), shooting preparation operations such as autofocusing, automatic exposure control, and automatic white balance adjustment are performed. When the release switch is further pushed in to a fully depressed state (hereinafter referred to as SW2), an actual photographing operation is performed.

  Furthermore, in recent years, there are cases where a touch panel display is used for a liquid crystal display screen in a digital camera capable of photographing while displaying and checking a subject on a liquid crystal panel screen. In such a digital camera, the SW1 and SW2 operations are realized on the touch panel by performing the shooting preparation operation on the SW1 by touching the touch panel and executing the shooting operation on the SW2 with no touch from the touch panel. This is possible (see Patent Document 1).

JP2011-193249A

  As described above, there is a method of reproducing the release switches SW1 and SW2 using a touch panel, but there are still problems in any of the conventional techniques, and countermeasures for that are required.

  In the example in which the SW1 state is realized by the start of touching the touch panel and the full-press SW2 state is realized when there is no contact from the touch panel, it is difficult to perform only the SW1 operation and only instruct the photographing preparation operation. In addition, it is difficult to operate only SW2, or to realize only a shooting command such as continuous shooting or bulb shooting while maintaining the SW2 state.

Therefore, in the present invention, when performing a long-time release such as continuous shooting or bulb shooting in a shooting instruction by touch operation, shooting can be continued even if the photographer does not maintain a long-time operation state, and operability is improved. The purpose is to improve.

In order to solve the above-described problem, the shooting control method of the present invention provides:
An imaging control device that controls imaging of an image by an imaging means,
Display control means for displaying the shooting button on the display screen of the display means;
Detecting means for detecting a touch operation on the display screen;

The shooting button is movable according to a touch operation for moving a touch position,
When the shooting button is moved to a predetermined position by a touch operation, the control unit performs control so as not to end the shooting process by the imaging unit even if the touch to the shooting button is released. Features.

According to the present invention, in a shooting instruction by touch operation , when performing a long-time release such as continuous shooting or bulb shooting, shooting can be continued even if the photographer does not maintain the operation state for a long time,
In addition, it is possible to provide a device that can be realized by an operation with good operability.

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

  FIG. 1 is a configuration diagram of a remote imaging system according to an embodiment of the present invention.

Example 1
Example 1 showing an embodiment of the present invention will be described below.

  FIG. 1 shows a schematic diagram of an interchangeable lens type imaging device 2.

  The interchangeable lens 1 generally includes a zoom lens 11 for changing a focal length, a diaphragm mechanism 12 for controlling brightness, and a focus lens 13 for focusing on a subject. In addition, the interchangeable lens 1 is configured such that the lens-side mount 14 can be mechanically joined to the mount portion 27 of the imaging device 2. The imaging device 2 reflects light that has passed through the lens with a half mirror 21 and forms an image at the position of the focusing plate 24. The light imaged on the focus plate 24 is inverted by the prism 25 and can be observed as an erect image through the eyepiece lens 26.

  Further, at the time of shooting, the half mirror 21 jumps up, the shutter 22 opens, and the light passing through the lens 1 forms an image on the image sensor 23.

  A contact group 15 is incorporated in the mount portion 14 of the interchangeable lens 1. The contact group 15 is a contact (not shown) for supplying power from the imaging device 2 main body and performing communication. The contact group 15 is divided into applications such as power supply, ground, transmission, reception, and clock.

  The mount part 14 of the interchangeable lens 1 is joined to the mount part 27 of the imaging device 2, whereby the contact group 15 in the mount part 14 and the connection terminal in the contact group 28 in the mount part 27 are connected to each other. .

  As a result, power is supplied from the imaging device 2 to the interchangeable lens 1 via the connection terminal, and communication is started between the interchangeable lens 1 and the imaging device 2.

  Reference numeral 42 denotes a communication interface. In FIG. 1, the imaging device 2 and the display control device 10 are connected via the communication interface 42.

  Next, FIG. 2 shows a block configuration inside the imaging apparatus 2.

  The image sensor 23 is a sensor such as a CCD or a CMOS, and light imaged on the image sensor 23 via the lens 1 is converted into an amount of electric charge corresponding to the amount of incident light in each pixel in the image sensor 23. The The signal generated by the timing generator 32 drives the image sensor 23, transmits the charge accumulated in the sensor, and is sequentially converted into a voltage signal. The converted voltage signal is sampled by correlated double sampling 30 (hereinafter referred to as CDS) and converted to a digital signal by A / D converter 31. The image data converted into the digital signal is input to the IC 33, and first enters the WB circuit 33a for calculating a parameter for white balance with respect to the data, and is temporarily stored in the memory 1 of 35, and if necessary. The data is processed.

  At the time of live view display, the half mirror 21 jumps up, opens the shutter 22, and the light passing through the lens 1 forms an image on the image sensor 23. The captured image data is stored in the memory 2 of 37, a live view image is written in the VRAM 40, and a live view display is performed on the rear display 43 installed in the imaging apparatus 2 by the video IC 41 for display control. Live view display updates the captured images at regular intervals, replacing the confirmation of the subject to be photographed through the optical viewfinder. The user can take a picture by checking the live view on the rear display 43 and operating the release button 40 at a desired timing.

  The switch 40 connected to the CPU 36 is a release switch. The release switch has a non-pressed state, a full-pressed state (SW2) in which the push button is pushed to the movable end, and a half-pressed state (SW1) in between. When the release switch is in the SW1 state, the CPU 36 outputs a shooting preparation process start command, that is, a shooting preparation command, and executes shooting preparation operations such as autofocusing, automatic exposure control, and adjustment of shooting settings such as automatic white balance. . In other words, the WB circuit 33a calculates parameters for white balance adjustment, and the CPU 36 or the IC 33 performs calculation for automatic focus adjustment and automatic exposure adjustment and photographing preparation control. Then, in accordance with the calculation result, data processing in the image processing circuit 33b and adjustment of the lens 1 are performed to execute shooting preparation processing such as automatic focus adjustment and automatic exposure adjustment. When the release switch is further operated to the state of SW2 after performing the shooting preparation operation in SW1, the CPU 36 outputs a shooting operation start command to perform shooting control, and a shooting operation described later is executed. The image is written to When the continuous shooting mode is set, if the release switch is in the SW2 state, the shooting operation is repeated until the release switch is not pressed or until the SW1 state is reached. That is, as long as the release switch is in the SW2 state, continuous shooting is performed and a plurality of images are continuously captured. When the release switch changes from the state of SW2 to the other state, that is, the state of SW1 or not pressed, the CPU 36 outputs a shooting stop command, and the continuous shooting operation ends.

  At the time of shooting operation, the data stored in the memory 1 of 35 is again input to the IC 33 and subjected to the following three image processes. First, the image data converted into a digital signal is converted into RAW data that has been losslessly compressed by a lossless compression circuit 33d that performs lossless compression (reversible compression), and is sent to the CPU bus 34. The image data converted into a digital signal is sent to the CPU bus 34. Finally, in order to create an image for jpeg compression, image processing is performed in the image processing circuit 33b, and YcbCr output as a result is subjected to raster block conversion, and jpeg compression is performed in the jpeg compression circuit 33e. It is sent to the CPU bus 34. The CPU 36 once stores the image data output to the CPU bus 34 as the captured image data in the memory 1 35 and finally writes it in the external memory 39 via the interface circuit 38.

  Immediately after the power is turned on, the CPU 36 initializes the imaging device 2 and communicates with the interchangeable lens according to the program in the memory 37. The CPU 36 controls each block of the imaging device 2 according to a program read from the memory 2 of 37 and executes each process. The flow to be described later is also realized by the CPU 36 controlling the operation of each block based on the read program.

  Reference numeral 42 denotes a communication interface. In FIG. 1, the imaging apparatus 2 and the display control apparatus 10 are connected via a communication interface 42, and various data such as image data, commands (command signals), and the like are connected via the communication interface 42. Send and receive. The imaging device 2 not only executes a shooting operation in response to a shooting operation start command output from the CPU 36 in response to SW2, but also receives a shooting operation start command received from the display control device 100 via the communication interface 42. The camera is configured to execute a shooting operation in response. Similarly, the shooting preparation operation is configured to execute the shooting preparation operation in response to receiving a shooting preparation operation start command from the display control device. With such a configuration, it is possible to perform remote shooting in which a shooting instruction is given from an external device other than the shooting device 2. Also, when remote shooting is performed using an external display control device, a live view image is periodically transmitted to the display control device via the communication I / F 42 and shot while checking the live view image on the display control device side. It may be configured to be able to perform an operation.

  FIG. 3 shows an example of the configuration of the display control apparatus 100 to which the present invention can be applied. The display control device 100 is configured by a personal computer, a smartphone (hereinafter referred to as a PC) or the like.

  In FIG. 3, a CPU 101, a memory 102, a nonvolatile memory 103, an image processing unit 104, a display 105, an operation unit 106, a recording medium I / F 107, and a communication I / F 109 are connected to an internal bus 150. Each unit connected to the internal bus 150 can exchange data with each other via the internal bus 150.

  The memory 102 is composed of, for example, a RAM (a volatile memory using a semiconductor element). The CPU 101 controls each unit of the display control apparatus 100 using the memory 102 as a work memory, for example, according to a program stored in the nonvolatile memory 103. Processing described later is realized by the CPU 101 controlling each unit based on a program read from the nonvolatile 103 memory. The nonvolatile memory 103 stores image data, audio data, other data, various programs for operating the CPU 101, and the like. The nonvolatile memory 103 is composed of, for example, a hard disk (HD) or ROM.

  The image processing unit 104 performs various image processing on the image data stored in the nonvolatile memory 103 and the recording medium 108, the image data acquired via the communication I / F 110, and the like based on the control of the CPU 101. The image processing performed by the image processing unit 104 includes A / D conversion processing, D / A conversion processing, image data encoding processing, compression processing, decoding processing, enlargement / reduction processing (resizing), noise reduction processing, and color conversion. Processing etc. are included. The image processing unit 104 may be configured with a dedicated circuit block for performing specific image processing. Further, depending on the type of image processing, the CPU 101 can perform image processing according to a program without using the image processing unit 104.

  The display 105 displays an image or a GUI screen constituting a GUI (Graphical User Interface) based on the control of the CPU 101. The CPU 101 generates a display control signal according to a program, and controls each unit of the display control apparatus 100 so as to generate a video signal to be displayed on the display 105 and output it to the display 105. The display 105 displays a video based on the output video signal. The display control apparatus 100 itself may include an interface for outputting a video signal to be displayed on the display 105, and the display 105 may be configured with an external monitor (such as a television).

  The operation unit 106 is an input device for receiving user operations including a character information input device such as a keyboard, a pointing device such as a mouse and a touch panel, buttons, dials, joysticks, touch sensors, touch pads, and the like. In the present embodiment, a touch panel is superimposed on the display 105 to form a plane, and coordinate information corresponding to the position touched on the display screen of the spray 105 is output from the touch panel.

  The storage medium I / F 107 can be loaded with a recording medium 108 such as a memory card, a CD, or a DVD. Under the control of the CPU 101, data can be read from the loaded recording medium 108 and data can be written to the recording medium 108. I do. The communication I / F 109 is an interface that is connected to an external device or the Internet by a wired cable or wirelessly and transmits / receives various data such as image data, audio signals, files, and commands. In the present embodiment, image data such as a live view image is received from the connected imaging device 2 via the communication I / F 109, and commands such as a shooting start command, a shooting preparation start command, and a shooting stop command are shot. Send to device.

  The operation unit 106 configured with a touch panel allows the CPU 101 to detect the following operations on the touch panel. Touching the touch panel with a finger or a pen (hereinafter referred to as touchdown). The touch panel is touched with a finger or a pen (hereinafter referred to as touch-on). The touch panel is moved while being touched with a finger or a pen (hereinafter referred to as a move). The finger or pen that was touching the touch panel is released (hereinafter referred to as touch-up). A state where nothing is touched on the touch panel (hereinafter referred to as touch-off). The CPU 101 is notified of these operations and the position coordinates where the finger or pen touches the touch panel via the internal bus 150, and the CPU 101 determines what operation has been performed on the touch panel based on the notified information. . Regarding the move, the moving direction of the finger or pen moving on the touch panel can also be determined for each vertical component / horizontal component on the touch panel based on the change of the position coordinates. It is also assumed that a stroke is drawn when touch-up is performed on the touch panel through a certain move from touch-down. The operation of drawing a stroke quickly is called a flick. A flick is an operation of quickly moving a certain distance while touching a finger on the touch panel and then releasing it, in other words, an operation of quickly tracing a finger on the touch panel. If it is detected that the moving is performed at a predetermined speed or more over a predetermined distance, and a touch-up is detected as it is, it can be determined that a flick has been performed. In addition, when it is detected that the movement is performed at a predetermined distance or more and less than a predetermined speed, it is determined that the drag has been performed. The touch panel may use any of various types of touch panels such as a resistive film type, a capacitance type, a surface acoustic wave type, an infrared type, an electromagnetic induction type, an image recognition type, and an optical sensor type. .

  Next, a method of remote imaging control in a remote imaging system in which the display control device 100 in FIG. 1 and the imaging device 2 are connected via the external interface 38 of the present invention will be described with reference to FIGS.

  The live view display screen is displayed on the touch panel display 51 which is the display 105 of the display control device. As described above, the live view acquired periodically from the imaging device 2 is acquired, and the received image is displayed on the touch panel display 51.

  FIG. 4A is a display example of the operation / display screen 310 of the touch panel display 51 of the display control apparatus 100 during remote shooting. When the imaging device 2 connected to the display control device 100 starts live view, a live view image is transmitted from the imaging device 2 to the display control device 100. Then, the live view image acquired from the imaging device 2 is displayed on the live view display screen 311 installed on the operation / display screen 310 of the display control apparatus 100 (remote live view). The display on the operation / display screen 310 is realized by the CPU 36 performing display control based on the live view image received via the communication I / F 109 and the data stored in the nonvolatile memory 103.

  On the operation / display screen 310, an operation icon 313 for indicating SW2 (hereinafter referred to as SW2 button 313) and an operation icon 314 for indicating SW1 (hereinafter referred to as SW1 button 314) are provided as an operation unit for instructing a shooting command. Are displayed respectively. When the photographer touches the icon display area, the SW1 button 314 and the SW2 button 313 are changed to a display in which the button is depressed, and the photographer can recognize that the button has been pressed in the same manner as the mechanical button. Yes.

  Further, the SW1 button 314 and the SW2 button 313 are arranged so that the SW1 button 314 and the SW2 button 313 are within the range of the movable region of the thumb, for example, so that the SW1 operation and the SW2 operation can be performed with one hand operation. The SW1 button 314 is arranged at a position away from the SW2 button 313, but is configured to be slidable toward the SW2 button 313. As shown in FIG. 4A, it is preferable to display that the SW1 button 314 is slidable by displaying a guideline 315 indicating the sliding direction of the SW1 button 314.

  An operation icon 312 (hereinafter, an enlargement / reduction button 312) is an operation member for switching between enlargement and reduction display of the display area of the live view display screen 311. When the enlargement / reduction button 312 is operated in the display state of the live view screen 311 as shown in FIG. 4A, the live view screen as shown in FIG. 4B is enlarged and displayed. The arrangement of the SW2 button 313 and the SW1 button 314 is changed in accordance with the enlargement of the live view screen. That is, in FIG. 4A, the SW2 button and the SW1 button are arranged in the vertical direction and SW1 is slidable in the vertical direction, but in FIG. 4B, the SW2 button and the SW1 button are horizontal in the figure. Aligned in the direction, SW1 can slide in the horizontal direction. This is because when the live view display screen 311, the SW2 button 313, and the SW1 button 314 are arranged in the same direction (vertical direction in the figure), the SW2 button 313 and the SW1 button 314 are arranged on the live view display screen 311. By enlarging in the vertical direction, the display area of the SW2 button 313 and the SW1 button 314 is narrowed. Therefore, by rotating the SW2 button 313 and the SW1 button 314 by 90 degrees and changing them so that they are aligned in the horizontal direction, the vertical area required for displaying the SW2 button and SW1 is reduced. Therefore, the live view display screen 311 can be sufficiently enlarged without overlapping the SW2 button 313, the SW1 button 314, and the live view display screen 311. Here, when the live view display screen 311, the SW2 button 313, and the SW1 button 314 are arranged side by side in the horizontal direction, the SW2 button 313 and the SW1 button are similarly applied when the live view display screen 311 is expanded in the horizontal direction. 314 may be rotated 90 degrees for display.

  When the photographer detects that the position of the SW2 button 313 is touched (contacted), the display control device 100 (CPU 101) transmits a photographing start command to the imaging device 2. Thereafter, when it is detected that the contact has been released from the SW2 button 313, an imaging stop command is transmitted to the imaging device 2. Further, when it is detected that the position of the SW1 button 314 is touched, a shooting preparation start command is transmitted to the imaging device 2, and when it is detected that the contact has been released from the SW1 button 314, the shooting preparation is stopped to the imaging device 2. Send instructions. Further, the SW1 button 314 can be moved by sliding the SW1 button 314 in the direction of the SW2 button 313 after the SW1 button 314 is touched. Therefore, after the SW1 button 314 is touched, the movement of the touch position is detected, and the display position of the SW1 button 314 is changed according to the touch position. Here, after the display position of the SW1 button 314 is touched, if the movement of the touch position is moved in a direction different from the direction in which the SW1 button 314 can slide, the CPU 101 may touch the SW1 button 314. Judged to have been released. When it is detected that the position of the SW1 button 314 is moved by the photographer's touch operation and the SW1 button 314 overlaps the SW2 button 313, a shooting start command is transmitted to the imaging apparatus 2.

  As described above, it is assumed that a series of operations in which the SW1 button 314 is slid and the SW2 button 313 is slid to issue a shooting command has the display control apparatus 100 with one hand as shown in FIG. ing. Further, a shooting preparation operation is performed by touching the SW1 button 314 with the thumb, and when preparation for shooting is completed, the thumb is slid toward the SW2 button 313 while the SW1 button is touched, and the SW1 button 314 is superimposed on the SW2 button 313. It is assumed that a shooting command is issued.

  In this embodiment, the operation with one hand is shown. However, since the SW1 button 314 and the SW2 button 313 have independent functions, the photographing preparation operation and the photographing can be performed with both hands or with two fingers. An operation may be performed.

  FIG. 6 is a flowchart of the release control of the display control apparatus 100 in the remote shooting according to this embodiment. These processes are realized by the CPU 101 performing control of each unit in FIG. 3, calculation, data processing, and the like based on a program read from the nonvolatile memory 103.

  The display control device 100 is connected to the imaging device 2 via the interface 38. The display control device 100 can communicate with the imaging device 2 and obtain information such as the shooting settings inside the imaging device 2 and the current state.

  In step S101, a power button (not shown) of the display control apparatus 100 is operated to turn on the power, and each part of the display control apparatus 100 is energized to be operable.

  In step S102, the display control apparatus 100 starts communication with the imaging apparatus 2 connected via the communication I / F 109, and transmits and receives information on each other apparatus. In particular, in remote shooting, since the display control apparatus issues a shooting instruction, the display control apparatus 100 receives current setting information from the imaging apparatus 2 in step S102. Here, the setting information refers to shooting setting information such as shooting mode setting information, white balance setting information, and information such as a live view state. The setting information of the imaging device 2 is obtained when the setting is changed by the photographer operating the imaging device 2 or when the setting of the imaging device 2 is changed by operating the display control device 100. An update notification is sent from the device 2 to the display control device 100.

  In step S103, the display control apparatus 100 notifies the imaging apparatus 2 of the start of the remote live view, and the imaging apparatus 2 starts the live view. When the imaging device 2 is notified of the start of the remote live view, the live view image is periodically transmitted from the imaging device 2 to the display control device 100.

  In step S104, the display control apparatus 100 displays the live view image acquired from the imaging apparatus 2 on the live view display screen 311 of the touch panel display 51, and performs live view display according to the live view image received periodically. Update.

  In step S105, the CPU 101 of the display control apparatus 100 determines whether or not the SW1 button 314 displayed on the touch panel display 51 is touched. If it is determined that the SW1 button 314 is touched, the process proceeds to step S106. If the SW1 button 314 is not touched, the process proceeds to step S110.

  When it is detected in step S105 that the SW1 button 314 has been touched, a shooting preparation start command is transmitted to the imaging apparatus 2 via the communication I / F 109 in step S106 in order to cause the imaging apparatus 2 to execute shooting preparation processing. Then, the imaging apparatus is made to execute shooting preparation. Thereafter, the process proceeds to step S107. In step S107, it is determined whether the touch position is moved while the SW1 button 314 is touched and a touch operation for sliding the SW1 button is performed. If it is determined that the SW1 slide operation has been performed, the process proceeds to step S108, where the slide operation is performed to a position where the SW1 button and the SW2 button overlap, and it is determined whether or not the slid SW1 button 314 overlaps the SW button 313. . If it is determined in step S107 that the slide operation is not performed, or if it is determined in step S108 that the SW1 button and the SW2 button are not overlapped, the process proceeds to step S110.

  If it is determined in step S108 that the SW1 button and SW2 button overlap, in step S109, the SW1 button 314 that has been slid to the position where it overlaps with the SW2 button is returned to the original display position. In step S111, a shooting start command is transmitted to the imaging apparatus 2. That is, when the photographer touches the SW1 button and then operates to slide SW1 so as to overlap SW2, the imaging operation is performed by the imaging device 2.

  Here, in S108, the method of determining whether SW1 has slid to the position where the SW1 button and SW2 button overlap each other may be performed by comparing the display position of the SW1 button and the display position of the SW2 button. Alternatively, it may be determined whether the SW1 button and the SW2 button overlap each other by comparing the touch position detected for the slide operation of the SW1 button with a predetermined display position of the SW2. Further, when the SW1 button is slid, the touch position when the SW1 button and the SW2 button overlap is determined in advance and recorded in the nonvolatile memory 103, and the detected touch position is set to the predetermined position. When it becomes, you may determine with having overlapped. In this case, the touch coordinates when they are overlapped in advance are recorded as threshold values, and when the touch coordinates detected during the SW1 slide operation exceed the threshold values, the SW1 button and the SW2 button are regarded as overlapping. It is preferable to send a shooting start command.

  In addition, regarding what state is the state in which the SW1 button and the SW2 button overlap, a state in which part of the button display area overlaps may be defined as the SW1 button and the SW2 button overlapping. . In addition, the button display itself does not overlap, and the state defined as the button display area in the CPU 101 is included in the area defined as the display area of the other button when the SW1 button and the SW2 button overlap. It may be defined.

  In step S110, the CPU 101 determines whether or not the SW2 button 313 displayed on the touch panel display 51 is touched. If it is determined in step S100 that the touch has been made, a shooting start command is transmitted to the imaging apparatus 2 through the communication I / F 109 in step S111. In step S112, it is determined whether or not the touch on the SW2 button 313 has been released. If the touch is released, a shooting stop command is transmitted to the imaging apparatus 2 in step S113. That is, while the SW2 button is being touched, the imaging operation is continuously performed in the imaging device 2.

  In step S115, the CPU 101 determines whether or not the touch on the SW1 button 314 displayed on the touch panel display 51 has been released. If it is determined that the touch on the SW1 button has been released, a shooting preparation stop command is transmitted to the imaging apparatus 2 in SW1 step S114. That is, the shooting preparation operation in the imaging device 2 is stopped in response to the touch on the SW1 button being released.

  During remote shooting, the processing from step S106 to step S115 is repeated.

  In step S116, the operation / display screen 301 is closed, the imaging device 2 is notified of the end of the live view, and the remote live view is ended.

  If communication is disconnected in step S117, the power is turned off in step S118 and the process is terminated.
