  EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated in detail with reference to an accompanying drawing.

  <Apparatus Configuration> With reference to FIG. 1 and FIG. 2, the function and appearance of an image pickup apparatus according to an embodiment to which the present invention is applied (in this embodiment, a digital camera is taken as an example) will be described.

  In FIG. 1 showing the external appearance of the digital camera 100 of the present embodiment, a display unit 101 includes a liquid crystal display panel (LCD) that displays images and various types of information. The shutter button 102 is an operation unit for issuing a shooting instruction. A mode switching button 103 is an operation unit for switching various modes. A connector 107 is an interface for connecting the connection cable 108 and the digital camera 100. The operation unit 104 is an operation unit including operation members such as various switches, buttons, and a touch panel that accept various operations from the user. The controller wheel 106 is a rotatable third rotating member included in the operation unit 104. The smooth ring 112 and the click ring 113 are two-stage dial type rotating members that can rotate around the lens barrel. The smooth ring 112 is a second rotating member on the front side (subject side) with respect to the optical axis direction, and the click ring 113 is a first rotating member on the rear side (photographer side). Shaft). As will be described later, the user can execute the function assigned to each member by rotating the smooth ring 112, the click ring 113, and the controller wheel 106 for each shooting mode. The power button 105 is an operation unit for switching power on and power off. The recording medium 109 is a recording medium such as a memory card or a hard disk. The recording medium slot 110 is a slot for storing the recording medium 109. The recording medium 109 stored in the recording medium slot 110 can communicate with the digital camera 100. A lid 111 is a lid of the recording medium slot 110.

  In FIG. 2 showing the internal configuration of the digital camera 100 of the present embodiment, a photographing lens 203 is a lens group including a zoom lens and a focus lens. The shutter 204 has an aperture function. The image pickup unit 205 is an image pickup element configured by a CCD, a CMOS, or the like that converts an optical image of a subject into an electric signal. The A / D converter 206 converts an analog signal into a digital signal. The A / D converter 206 is used to convert an analog signal output from the imaging unit 205 into a digital signal. The barrier 202 covers the imaging system including the imaging lens 203 of the digital camera 100, thereby preventing the imaging system including the imaging lens 203, the shutter 204, and the imaging unit 205 from becoming dirty or damaged.

  The image processing unit 207 performs resizing processing and color conversion processing such as predetermined pixel interpolation and reduction on the data from the A / D converter 206 or the data from the memory control unit 209. The image processing unit 207 performs predetermined calculation processing using the captured image data, and the system control unit 201 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 207 further performs predetermined arithmetic processing using the captured image data, and also performs TTL AWB (auto white balance) processing based on the obtained arithmetic result.

  Output data from the A / D converter 206 is directly written into the memory 210 via the image processing unit 207 and the memory control unit 209 or via the memory control unit 209. The memory 210 stores image data obtained by the imaging unit 205 and converted into digital data by the A / D converter 206 and image data to be displayed on the display unit 101. The memory 210 has a storage capacity sufficient to store a predetermined number of still images and a predetermined time of moving images and audio.

  The memory 210 also serves as an image display memory (video memory). The D / A converter 208 converts the image display data stored in the memory 210 into an analog signal and supplies the analog signal to the display unit 101. Thus, the display image data written in the memory 210 is displayed on the display unit 101 via the D / A converter 208. The display unit 101 performs display according to an analog signal from the D / A converter 208 on a display such as an LCD. A digital signal that has been A / D converted by the A / D converter 206 and accumulated in the memory 210 is converted into an analog signal by the D / A converter 208, and sequentially transferred to the display unit 101 for display, thereby displaying an electronic viewfinder. It can function as a through image display. In other words, the live view image is assumed to be a parallax image, and the live view is assumed to be a paraphrase of the live view display.

  The nonvolatile memory 213 is an electrically erasable / recordable memory, and for example, an EEPROM or the like is used. The nonvolatile memory 213 stores constants, programs, and the like for operating the system control unit 201. Here, the program is a program for executing various flowcharts described later in the present embodiment.

  The system control unit 201 controls the entire digital camera 100. By executing the program recorded in the non-volatile memory 213 described above, each process of the present embodiment to be described later is realized. A system memory 212 uses a RAM. In the system memory 212, constants and variables for operation of the system control unit 201, programs read from the nonvolatile memory 213, and the like are expanded. The system control unit 201 also performs display control by controlling the memory 210, the D / A converter 208, the display unit 101, and the like.

  The system timer 211 is a time measuring unit that measures the time used for various controls and the time of a built-in clock.

  The mode switching button 103, the first shutter switch 102a, the second shutter switch 102b, and the operation unit 104 are operation means for inputting various operation instructions to the system control unit 201.

  A mode switching button 103 switches the operation mode of the system control unit 201 to any one of a still image shooting mode, a moving image recording mode, a reproduction mode, and the like. As modes included in the still image recording mode, there are an auto mode, an auto scene discrimination mode, a manual mode, a shooting mode for each shooting scene, a program AE mode, a custom mode, and the like. A mode switching button 103 is used to directly switch to one of these modes included in the still image recording mode. Alternatively, after switching to the still image recording mode once with the mode switching button 103, switching to any one of these modes included in the still image recording mode may be performed using another operation member. Similarly, the moving image recording mode may include a plurality of modes.

  The first shutter switch 102a is turned on when the shutter button 102 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 processing, AE processing, AWB processing, and EF processing are started.

  The second shutter switch 102b is turned on when the operation of the shutter button 102 is completed, so-called full press (shooting instruction), and generates a second shutter switch signal SW2. In response to the second shutter switch signal SW2, the system control unit 201 starts a series of shooting processing operations from reading a signal from the imaging unit 205 to writing image data on the recording medium 109 (shooting control).

  Each operation member of the operation unit 104 is appropriately assigned a function for each scene by selecting and operating various function icons displayed on the display unit 101, 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 101. The user can make various settings intuitively using the menu screen displayed on the display unit 101 and the four-way buttons and the SET button.

  Note that as one of the operation units 104, a touch panel capable of detecting contact with the display unit 101 is provided. The touch panel and the display unit 101 can be configured integrally. For example, the touch panel is configured so that the light transmittance does not hinder the display of the display unit 101, and is attached to the upper layer of the display surface of the display unit 101. Then, the input coordinates on the touch panel are associated with the display coordinates on the display unit 101. Thereby, it is possible to configure a GUI as if the user can directly operate the screen displayed on the display unit 101.

  The controller wheel 106 is a rotatable operation member included in the operation unit 104, and is used when a selection item is designated together with a direction button. When the controller wheel 106 is rotated, an electrical pulse signal is generated according to the operation amount, and the system control unit 201 controls each unit of the digital camera 100 based on the pulse signal. Based on this pulse signal, it is possible to determine the angle at which the controller wheel 106 is rotated, how many rotations, and the like. The controller wheel 106 may be any operation member that can detect a rotation operation. For example, a dial operation member that generates a pulse signal by rotating the controller wheel 106 in accordance with a user's rotation operation may be used. Further, an operation member made of a touch sensor may be used to detect a rotation operation of a user's finger on the controller wheel 106 without rotating the controller wheel 106 itself (so-called touch wheel). Similarly, when the smooth ring 112 and the click ring 113 are rotated, an electric pulse signal is generated according to the operation amount, and the system control unit 201 controls each part of the digital camera 100 based on the pulse signal. Control.

  The power control unit 214 includes a battery detection circuit, a DC-DC converter, a switch circuit that switches a block to be energized, and the like, and detects whether or not a battery is attached, the type of battery, and the remaining battery level. Further, the power control unit 214 controls the DC-DC converter based on the detection result and an instruction from the system control unit 201, and supplies a necessary voltage to each unit including the recording medium 109 for a necessary period.

  The power supply unit 215 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 lithium ion battery, an AC adapter, or the like. The recording medium I / F 216 is an interface with the recording medium 109 such as a memory card or a hard disk. The recording medium 109 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 217 is communicably connected to an external device via a wireless antenna or a wired cable, and transmits and receives video and audio. The communication unit 217 can be connected to a wireless LAN (Local Area Network) or the Internet. The communication unit 217 can transmit image data (including a through image) captured by the imaging unit 205 and an image file recorded on the recording medium 109 to an external device, and image data and other various information from the external device. Can be received.

  The posture detection unit 218 detects the posture of the digital camera 100 with respect to the direction of gravity. According to the posture detected by the posture detection unit 218, it is possible to determine whether the image captured by the image capturing unit 205 is taken with the digital camera 100 held sideways or taken vertically. is there. The system control unit 201 can add information related to the posture detected by the posture detection unit 218 to the image data captured by the imaging unit 205 or rotate and record the image data. As the attitude detection unit, an acceleration sensor, a gyro sensor, or the like can be used.

The digital camera 100 can be switched between at least a playback mode for playing back an image and a shooting mode for shooting. The shooting mode includes an auto mode, a plus movie auto mode, a manual mode (M), an aperture priority AE mode (Av), a shutter speed priority AE mode (Tv) mode, and a program AE mode (P). Further, as shooting modes, a creative shot mode, a creative filter mode, and a plurality of scene-specific shooting modes (SCN) are provided. The auto mode is a mode in which various parameters of the camera are automatically determined by a program incorporated in the digital camera 100 based on the measured exposure value. The plus movie auto mode is a mode in which a scene several seconds before immediately before the user issues a shooting instruction (SW2 on) is recorded as a moving image. The M mode is a mode in which various parameters of the camera can be freely changed by the user. The Av mode is a mode in which the camera automatically determines the shutter speed so that the appropriate exposure is obtained when the user determines the aperture. The Tv mode is a mode in which the camera automatically determines the aperture so that the appropriate exposure is obtained when the shutter speed is determined. The P mode is a mode in which the camera automatically sets the shutter speed and the aperture according to the brightness of the subject. In Creative Shot mode, the camera automatically identifies the scene, and the captured image is automatically subjected to image processing (filter processing) such as “Composition”, “Color / Light”, “Bokeh”, etc. This is a mode for generating (including the original image). For example, “Retro (old texture)”, “Monochrome (select from black and white, sepia, blue)”, “Special (special and bold effect)”, “Natural (suppress natural impression) "Effective effect)", "Auto (camera is selected from all effects)", etc. In the creative filter mode, the camera performs pre-selected filter processing on the captured image to generate a new image, For example, “rough monochrome (contrast adjustment)”, “soft focus (blurring condition)”, “fish-eye style”, “toy camera style (color tone)”, “diorama style” (Selection of a portion to be clearly displayed) ”, etc. The scene-specific shooting mode (SCN) is a shutter suitable for the shooting scene for each shooting scene. This mode is realized by combining speed, aperture, strobe lighting, sensitivity setting, white balance (WB) setting, etc. The digital camera 100, for example, captures by scene (1) to (15) described below. However, the present invention is not limited to these scene-specific shooting modes.

  <Assignment of Functions for Each Shooting Mode> Next, functions assigned to the smooth ring 112, the click ring 113, and the controller wheel 106 for each shooting mode will be described with reference to FIGS.

  As shown in FIG. 8, in the auto mode and / or the plus movie auto mode, the zoom ring setting operation in the step zoom function is assigned to the click ring 113. There are no functions assigned to the smooth ring 112 and the controller wheel 106. In this way, by assigning the step zoom function to the click ring 113, the user can set a desired zoom magnification using a rotary operation member having a click feeling. Note that the smoothing ring 112 may be used to set the zoom magnification in the auto mode or the plus movie auto mode. Thereby, the user can obtain a manual operation feeling.

  In the case of the creative shot mode, a category selection function is assigned to the click ring 113. There are no functions assigned to the smooth ring 112 and the controller wheel 106. As described above, by assigning the creative shot category selection function to the click ring 113, the user can select a desired category while operating the rotation operation member having a click feeling.

  In the creative filter mode, a filter switching function is assigned to the click ring 113, a filter effect setting function is assigned to the smooth ring 112, and no function is assigned to the controller wheel 106. By assigning functions to the click ring and smooth ring in this way, the user can set the strength of the filter effect by operating a rotation operation member without a click feeling, and by operating a rotation operation member with a click feeling. The filter effect can be switched. The smoothing ring 112 is assigned the above-described filter effect setting function in the case of autofocus (AF), but when switched to manual focus (MF) or manual focus (AF + MF) after autofocus (AF), As will be described later with reference to FIG. 6, the focus adjustment function is assigned with priority over other functions. The AF + MF function is a function that can finely adjust the focus with manual focus after focusing with AF, and enables higher-precision focusing.

  In the scene-by-scene shooting mode (SCN), a scene switching function is assigned to the click ring 113, and no function is assigned to the smooth ring 112 and the controller wheel 106.

In the case of aperture priority AE mode (Av), aperture (Av), invalid (initial setting), exposure correction value, D range correction value, dark area correction value, ISO sensitivity, WB correction value, aspect ratio, and step A zoom magnification setting function can be assigned. A shutter speed (Tv) setting function cannot be assigned. Further, in the shutter speed priority AE mode (Tv), the shutter speed (Tv), invalid (initial setting), exposure correction value, D range correction value, dark part correction value, ISO sensitivity, WB correction value, aspect ratio, A step zoom magnification setting function can be assigned. A function for setting the aperture (Av) cannot be assigned. Furthermore, in the case of the program AE mode (P), setting function of invalidity (initial setting), exposure correction value, D range correction value, dark area correction value, ISO sensitivity, WB correction value, aspect ratio, and step zoom magnification Can be assigned. A function for setting the aperture (Av) and the shutter speed (Tv) cannot be assigned.

  As described above, since a desired function can be assigned to the controller wheel 106, the user can adjust the aperture, shutter speed, exposure correction value, D range correction value, dark portion correction value, ISO sensitivity, white balance correction value, aspect ratio, zoom You can set the magnification.

  Next, functions assigned to the click ring 113 in manual focus (MF) or manual focus (AF + MF) after autofocus (AF) will be described with reference to FIG.

  As shown in FIG. 11, the function that can be assigned to the click ring 113 is a function that switches the type of imaging parameter that can be set. Then, after switching the type, parameters can be set using a smooth ring, a controller wheel, or other operation members.

  For example, in the manual mode, the shutter speed (Tv) and the aperture (Av) (initial setting), the D range correction value, the shutter speed (Tv) and the aperture (Av), and dark part correction are selected as the types of shooting parameters to be switched. Value, shutter speed (Tv) and aperture (Av), ISO sensitivity, shutter speed (Tv) and aperture (Av), WB correction value, shutter speed (Tv) and aperture (Av), aspect ratio and shutter speed (Tv) And aperture (Av), step zoom, shutter speed (Tv), and aperture (Av) can be switched.
