  FIG. 3 is a block diagram illustrating a configuration example of the digital camera 100 according to the present embodiment. In FIG. 3, a lens unit 150 is a lens unit on which a replaceable photographic lens is mounted.

  The lens 103 is usually composed of a plurality of lenses, but here, only a single lens is shown for simplicity. The communication terminal 6 is a communication terminal for the lens unit 150 to communicate with the digital camera 100 side, and the communication terminal 10 is a communication terminal for the digital camera 100 to communicate with the lens unit 150 side. The lens unit 150 communicates with the system control unit 50 through the communication terminals 6 and 10, controls the diaphragm 1 through the diaphragm driving circuit 2 by the internal lens system control circuit 4, and passes through the AF driving circuit 3. The focus is adjusted by displacing the position of the lens 103.

  The AE sensor 17 measures the luminance of the subject that has passed through the lens unit 150. The focus detection unit 11 outputs defocus amount information to the system control unit 50. Based on this, the system control unit 50 controls the lens unit 150 to perform phase difference AF.

  The quick return mirror 12 (hereinafter, mirror 12) is instructed by the system control unit 50 during exposure, live view shooting, and moving image shooting, and is moved up and down by an actuator (not shown). The mirror 12 is a mirror for switching the light beam incident from the lens 103 between the viewfinder 16 side and the imaging unit 22 side. The mirror 12 is normally arranged so as to reflect the light beam to the viewfinder 16, but when shooting is performed or in live view display, the mirror 12 is directed upward to guide the light beam to the imaging unit 22. Retreat from the bounced light flux (mirror up). Further, the mirror 12 is a half mirror so that the central part can transmit part of the light, and part of the light beam is transmitted so as to enter the focus detection part 11 for performing focus detection.

  The photographer can check the focus and composition of the optical image of the subject obtained through the lens unit 150 by observing the focusing screen 13 via the pentaprism 14 and the finder 16. The eyepiece detection unit 16a detects that the photographer has touched the viewfinder and notifies the system control unit 50 of it. The shutter 101 is a focal plane shutter that can freely control the exposure time of the imaging unit 22 under the control of the system control unit 50.

  The imaging unit 22 is an imaging device configured by a CCD, a CMOS device, or the like that converts an optical image into an electrical signal, and can also detect a focus based on a phase difference. The A / D converter 23 converts an analog signal into a digital signal. The A / D converter 23 is used to convert an analog signal output from the imaging unit 22 into a digital signal.

  The image processing unit 24 (including the defocus calculation unit) performs resizing processing and color conversion processing such as predetermined pixel interpolation and reduction on the data from the A / D converter 23 or the data from the memory control unit 15. Further, the image processing unit 24 includes a defocus calculation unit 25 that calculates a defocus amount due to a phase difference on the imaging surface using the captured image data. Further, predetermined calculation processing is performed based on the image data, and the system control unit 50 performs exposure control and distance measurement control based on the obtained calculation result. Thereby, AF (autofocus) processing, AE (automatic exposure) processing, and EF (flash pre-emission) processing of the TTL (through-the-lens) method are performed.

  The image processing unit 24 further performs predetermined calculation processing using the captured image data, and also performs TTL AWB (auto white balance) processing based on the obtained calculation result. Output data from the A / D converter 23 is directly written into the memory 32 via the image processing unit 24 and the memory control unit 15 or via the memory control unit 15. The memory 32 stores image data obtained by the imaging unit 22 and converted into digital data by the A / D converter 23 and image data to be displayed on the display unit 28. The memory 32 has a storage capacity sufficient to store a predetermined number of still images, a moving image and sound for a predetermined time.

  The memory 32 also serves as an image display memory (video memory). The D / A converter 19 converts the image display data stored in the memory 32 into an analog signal and supplies the analog signal to the display unit 28. Thus, the display image data written in the memory 32 is displayed on the display unit 28 via the D / A converter 19. The display unit 28 performs display according to the analog signal from the D / A converter 19 on a display such as an LCD. The digital signal once A / D converted by the A / D converter 23 and stored in the memory 32 is converted into an analog signal by the D / A converter 19 and sequentially transferred to the display unit 28 for display, thereby providing an electronic viewfinder. It functions and can perform live view display (live view display).

  On the in-finder liquid crystal display unit 41, a frame (AF frame) indicating a focus point currently being auto-focused, an icon indicating a camera setting state, and the like are displayed via the in-finder display unit driving circuit 42. Is done. Various setting values of the camera such as a shutter speed and an aperture are displayed on the liquid crystal display unit 43 outside the viewfinder via the display unit driving circuit 44 outside the viewfinder.

  The nonvolatile memory 56 is an electrically erasable / recordable memory, and for example, an EEPROM or the like is used. The nonvolatile memory 56 stores constants, programs, and the like for operating the system control unit 50. Here, the program is a program for executing various flowcharts described later in the present embodiment.

The mode changeover switch 60 can be directly switched to one of these modes. Alternatively, the mode changeover switch 60 may be used to temporarily switch to the shooting mode list screen, and then select one of the displayed modes and use another operation member for switching. Similarly, the moving image shooting mode may include a plurality of modes.

  The first shutter switch 62 is turned on when the shutter button 61 provided in the digital camera 100 is being operated, so-called half-press (shooting preparation instruction), and generates a first shutter switch signal SW1. In response to the first shutter switch signal SW1, operations such as AF (autofocus) processing, AE (automatic exposure) processing, AWB (auto white balance) processing, and EF (flash pre-emission) processing are started.

  The second shutter switch 64 is turned ON when the operation of the shutter button 61 is completed, that is, when it is fully pressed (shooting instruction), and generates a second shutter switch signal SW2. In response to the second shutter switch signal SW2, the system control unit 50 starts a series of shooting processing operations from reading a signal from the imaging unit 22 to writing image data on the recording medium 200.

  Each operation member of the operation unit 70 is appropriately assigned a function for each scene by selecting and operating various function icons displayed on the display unit 28, and functions as various function buttons. Examples of the function buttons include an end button, a return button, an image advance button, a jump button, a narrowing button, and an attribute change button. For example, when a menu button is pressed, various setting menu screens are displayed on the display unit 28. The user can make various settings intuitively using the menu screen displayed on the display unit 28, and the four-way button and the SET button.

Further, the power control unit 80 controls the DC-DC converter based on the detection result and an instruction from the system control unit 50, and supplies a necessary voltage to each unit including the recording medium 200 for a necessary period.

  The power supply unit 30 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. The recording medium I / F 18 is an interface with the recording medium 200 such as a memory card or a hard disk. The recording medium 200 is a recording medium such as a memory card for recording a captured image, and includes a semiconductor memory, a magnetic disk, or the like.

  The communication unit 54 is connected by wireless or wired cable, and transmits and receives video signals and audio signals. The communication unit 54 can be connected to a wireless local area network (LAN) or the Internet. The communication unit 54 can transmit an image captured by the imaging unit 22 (including a through image) and an image recorded on the recording medium 200, and can receive image data and other various types of information from an external device. it can.

  The posture detection unit 55 detects the posture of the digital camera 100 with respect to the direction of gravity. Based on the attitude detected by the attitude detection unit 55, it is determined whether the image shot by the imaging unit 22 is an image shot with the digital camera 100 held horizontally or an image shot with the image held vertically. It can be determined. The system control unit 50 can add orientation information corresponding to the orientation detected by the orientation detection unit 55 to the image file of the image captured by the imaging unit 22, or rotate and record the image. As the attitude detection unit 55, an acceleration sensor, a gyro sensor, or the like can be used.

  As one of the operation units 70, a touch panel 70a capable of detecting contact with the display unit 28 is provided. The touch detection unit 70b detects that the touch panel 70a has been touched and notifies the system control unit 50 of the touch. The touch panel 70a and the display unit 28 can be configured integrally.

  For example, the touch panel 70 a is configured such that the light transmittance does not hinder the display of the display unit 28, and is attached to the upper layer of the display surface of the display unit 28. Then, the input coordinates on the touch panel 70a are associated with the display coordinates on the display unit 28. Thereby, it is possible to configure a GUI (graphical user interface) as if the user can directly operate the screen displayed on the display unit 28. The system control unit 50 performs the following operations on the touch panel 70a. Alternatively, the state can be detected.

  -A finger or pen that has not touched the touch panel 70a newly touched the touch panel 70a. That is, the start of touch (hereinafter referred to as touch-down).

  The touch panel 70a is being touched with a finger or a pen (hereinafter referred to as touch-on).

  The touch panel 70a is moved while being touched with a finger or a pen (hereinafter referred to as “Touch-Move”).

  -The finger or pen that touched the touch panel 70a is released. That is, the end of touch (hereinafter referred to as touch-up).

  A state where nothing is touched on the touch panel 70a (hereinafter referred to as touch-off).

  When touchdown is detected, it is also detected that touch-on is performed at the same time. After touch-down, unless touch-up is detected, normally touch-on continues to be detected. The touch move is detected in a state where touch-on is detected. Even if the touch-on is detected, the touch move is not detected unless the touch position is moved. After it is detected that all fingers or pens that have been touched are touched up, the touch is turned off.

  These operations / states and the position coordinates at which the finger or pen touches the touch panel 70a are notified to the system control unit 50 through the internal bus, and the system control unit 50 determines which information on the touch panel 70a based on the notified information. It is determined whether such an operation (touch operation) has been performed. Regarding the touch move, the moving direction of the finger or pen moving on the touch panel 70a can also be determined for each vertical component / horizontal component on the touch panel 70a based on the change in position coordinates. When it is detected that a touch movement has been performed for a predetermined distance or more, it is determined that a slide operation (drag) has been performed.

  An operation of quickly moving a certain distance while touching a finger on the touch panel and releasing it is called a flick. In other words, the flick is an operation of quickly tracing the touch panel 70a with a finger. When it is detected that a touch move is performed at a predetermined speed or more at a predetermined distance or more and a touch-up is detected as it is, it can be determined that a flick has been performed (it can be determined that a flick has occurred following the drag). Furthermore, a touch operation in which a plurality of locations (for example, two points) are simultaneously touched to bring the touch positions closer to each other is referred to as pinch-in, and a touch operation that moves the touch positions away from each other is referred to as pinch-out.

  Pinch-out and pinch-in are collectively referred to as pinch operation (or simply pinch). The touch panel 70a may be any one 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. good. Depending on the method, there are a method for detecting that there is a touch due to contact with the touch panel, and a method for detecting that there is a touch due to the approach of a finger or pen to the touch panel, but either method may be used.

  4 and 5 are flowcharts of the system controller 50, and the operation of the camera will be described with reference to the flowcharts.

  In step S401 in FIG. 4, the system control unit 50 performs initial settings such as register initialization, data initialization, and peripheral part initialization. In step S402, the system control unit 50 detects various switches from the operation unit 70 and a touch state from the touch panel 70a. In step S403, touch processing is performed from the detection information of the touch state. This will be described in detail with reference to the flowchart of FIG.

  In step S501 in FIG. 5, the touch state is detected from the touch panel 70a, and if touched off, the process returns; otherwise, the process proceeds to step S502. In step S502, touch coordinates are detected from the touch panel 70a. In step S503, the camera state is detected. If the camera is not in the LV mode, touch processing in various setting modes is performed in step S504. Otherwise, the process proceeds to step S505. If the AF mode is autofocus in step S505, the distance measurement area is calculated from the touch coordinates in step S506, and the process returns. Otherwise, the process proceeds to step S507.

  If it is determined in step S507 that the touch detection result is a touchdown, a distance measurement area is calculated from the touch coordinates in step S508, and the process proceeds to step 511. Otherwise, the process proceeds to step S509. In step S509, the focus drive amount corresponding to the difference amount is calculated from the difference from the previous touch coordinates. Here, the vertical difference of touch coordinates is treated as a difference amount, and the horizontal difference is ignored.

In step S510, the lens is driven with the designated focus drive amount. In step S511, captured image data is acquired. In step S512, the defocus amount due to the phase difference on the imaging surface in the designated ranging area is calculated using the captured image data. In step S513, an enlarged display of the distance measurement area is created on the memory from the captured image data. In step S514, a focus guide display is created on the memory from the defocus amount.
Here, it demonstrates in detail by (a), (b), (c) of FIG.

  FIG. 6 is a focus guide display displayed on the LV display screen, and FIG. 6B shows an in-focus state. (A) shows the state of the front pin. From the in-focus state, the lower Δ mark is broken into two, and as the defocus amount increases, the two Δs are displayed away from each other. (C) shows the state of the rear pin, and from the in-focus state, the upper 割 れ mark is broken in two, and is similarly displayed away according to the defocus amount.

Returning to FIG. 5, in step S515, the enlarged display of the distance measurement area and the focus guide display are superimposed on the LV display screen on the memory.
Further, the enlarged display of the distance measurement area and the focus guide display are displayed at an empty position in the horizontal direction from the distance measurement area. In step S515, the LV display on the memory is updated to the display screen. Here, the display will be described with reference to FIG. 1, FIG. 7A and FIG.

  FIG. 7A shows a state where the screen is touched with a finger from a state where the liquid crystal display screen is not touched in the touch-down state. When touched down, as shown in FIG. 1, the touched-down location becomes a distance measurement area, and the distance measurement area is enlarged and displayed at the left and right open locations touched down. Further, the focus guide display in the distance measurement area is also displayed below the enlarged display. FIG. 7B shows a state in which the touched finger is shifted downward as compared with FIG. 1, so that the lens is shifted to the closest side and the focus is close to focusing.

  Returning to FIG. 4, if the menu button is pressed in step S404, various camera settings are performed in step S405, and the process proceeds to step S402. On the other hand, if the menu button is not pressed, the process proceeds to step S406.

  Here, referring to FIG. 8, the setting of “AF mode” will be described as an example of various camera settings.

  FIG. 8A is a camera setting menu screen displayed on the display unit 28, and has tabs from MENU1 to MENU4. The “AF mode” is on the MENU 4 tab, and when the “AF mode” is selected (FIG. 8A), when the SET button is pressed or a user touch operation to the “AF mode” is performed, The item “AF mode” is selected. Then, the display is switched to the setting screen of FIG. In FIG. 8B, “>>” indicates the currently selected setting, and “auto focus” or “manual focus” can be selected by a cross key or a user touch operation.

  Returning to FIG. 4, if SW1 and SW2 are OFF in step S406, the process proceeds to S407, and if not, the process proceeds to S408.

In step S408, the photometry timer is set to 6 seconds. In step S409, various information of the mounted lens unit 150 is read.
The lens information includes information such as lens specific information, focal length, aperture value, and focus lens position.

  In step S410, if the AF mode is autofocus, distance calculation is performed by a known phase difference detection method in order to focus on the subject. In addition, phase difference detection on the imaging surface and phase difference detection on the focus detection unit 11 are switched depending on the state of the camera (LV state or non-LV state). In step S411, the lens driving amount is calculated based on the data obtained by the distance measurement described above, and the lens is driven. Returning to step S407, if the photometry timer is not being used (when 6 seconds have elapsed), the process proceeds to step S416, and if not, the process proceeds to S412.

  In step S412, if the LV state, the photometric data is acquired from the captured image data, and if the non-LV state, the photometric data is acquired from the AE sensor 17. Then, photometric calculation is performed to determine the shutter speed, aperture value, and the like from camera setting information such as the set ISO sensitivity and shooting mode. In step S413, information on camera settings such as the shutter speed, aperture value, and distance measuring point area obtained by photometric calculation or the like is displayed on the display outside the viewfinder and the liquid crystal display in the viewfinder.

  In step S414, if SW2 is on, in step S415, well-known image sensor gain setting, accumulation operation, and readout operation are performed, and still image capturing operations such as image processing and image writing are performed. Thereafter, the process returns to step S402. If SW2 is not on, the process proceeds to step S416. If the power switch 72 is on in step S416, the process returns to step S402. Otherwise, the process proceeds to step S417. In step S417, in order to end the operation of the camera, an end setting such as an instruction to turn off the power to the peripheral circuits and data saving is performed, and this processing ends.

As described above, when the subject is touched on the LV screen display in the manual focus mode, the distance measurement area is determined, and the enlarged display of the distance measurement area and the focus guide information are displayed in a place that does not affect the touch move. .
Furthermore, when the touch move is performed from the touched state, the lens is driven in accordance with the amount of the touch move, so that a manual focus operation can be performed with one touch, and an operation that can easily focus on the focus guide information can be provided.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment, A various deformation | transformation and change are possible within the range of the summary.
