Description

Technical Field

[0001] The present invention relates to an electronic device and a method for controlling the electronic device.

Background Art

[0002] In recent years, electronic devices having a recording function such as digital cameras are provided with a signal processing engine for processing audio signals, which can arbitrarily program the configuration of a sound system (such as signal processing settings) according to various situations. On the display of these electronic devices, a screen (window) showing the signal processing configuration is displayed, and the user can construct the internal configuration of the sound system using an operation device. Specifically, the user can set the arrangement of control elements (components) for recording settings of various audio signal processes and the connection between each component on the display of a personal computer (PC). By setting the arrangement and connection of components, etc., the user can arbitrarily program the internal configuration (such as the content of signal processing) of the sound system. Components include mixers, compressors, various effects, faders, ON / OFF switches, etc. For example, the user can connect an arbitrary input terminal to the input side of an arbitrary component and an arbitrary output terminal to the output side of the component to connect the input terminal and the output terminal. As a result, the user can set, as a signal processing circuit of the signal processing engine, a signal communication path for outputting an audio signal input from an input terminal from an output terminal via the component.

[0003] The signal processing engine has a plurality of predetermined buses and outputs or records a plurality of audio signals input from a plurality of input terminals to an output terminal selected to form a specified signal processing circuit. Since the plurality of input terminals are connected to the output terminal via a plurality of buses, the internal structure of the signal processing engine is complex.

[0004] Each component can be classified according to its characteristics into those configured for input terminals and those configured for output terminals (recording side). When configuring a signal processing circuit that passes through each component of the signal processing engine, the user makes various settings related to the input and output terminals.

[0005] In electronic devices that process audio signals from multiple input terminals and output them to multiple output terminals, user configuration becomes complex. For example, cinema cameras display settings for all input and output terminals on the screen to accept user settings. However, it is difficult for users to construct signal processing circuits with multiple input and output terminals without fully understanding the complex internal configuration.

Best Mode for Carrying Out the Invention

[0012] <Embodiment><000​​​​​​​​The A / D converter 15 converts the analog signal (image signal) output from the image sensor 13 into a digital signal (image; image data). The digital signal converted by the A / D converter 15 is written to the memory 25 as RAW image data. The A / D converter 15 generates development parameters corresponding to the RAW image data based on the shooting information and writes them to the memory 25. The development parameters include various parameters such as exposure settings, white balance, color space, and contrast. These development parameters are used for image processing when recording images using the JPEG format, etc. The D / A converter 21 converts the digital signal (image; image data) output from the memory control unit 22 into an analog signal.

[0015] The timing generator 14 is a circuit that supplies clock signals and control signals to the image sensor 13, A / D converter 15, and D / A converter 21. The timing generator 14 is controlled by the memory control unit 22 and the system control unit 50.

[0016] The image processing unit 20 performs various image processing such as pixel interpolation, color conversion, correction, and resizing on the data from the A / D converter 15 or the data output from the memory control unit 22. The image processing unit 20 performs predetermined image processing and calculation processing using the captured image data and outputs the obtained results to the system control unit 50. Based on the results of the image processing and calculation processing by the image processing unit 20, the system control unit 50 controls the exposure control unit 40 and the distance measurement control unit 41 to perform AF (autofocus) processing, AE (automatic exposure) processing, and EF (flash pre-flash) processing.

[0017] The image processing unit 20 performs predetermined calculations using the captured image data and also performs AWB (Auto White Balance) processing based on the obtained calculation results. The image processing unit 20 reads the image stored in memory 25 and performs compression processing such as lossless compression or decompression processing. Images to be processed include JPEG format, MPEG-4 AVC (Advanced Video Coding) format, HEVC (High Efficiency Video Coding) format, and uncompressed RAW data images. The image processing unit 20 writes the processed data to memory 25.

[0018] The image processing unit 20 performs predetermined calculations using the captured image data and performs various image data editing processes. Specifically, the image processing unit 20 can perform cropping to adjust the display range and size of the image by hiding unnecessary parts around the image data. The image processing unit 20 can perform resizing to change the size of the image data and screen display elements by enlarging or reducing them. The image processing unit 20 can apply image processing such as color conversion to data that has undergone compression or decompression processing, such as lossless compression, on uncompressed RAW data. Through such image processing, the image processing unit 20 can realize RAW development to create image data converted to JPEG format, and video extraction processing to extract specified frames from video formats such as MPEG-4, convert them to JPEG format, and save them.

[0019] The image processing unit 20 performs the process of superimposing an OSD (On-Screen Display) such as a menu and arbitrary characters to be displayed on the display unit 23 along with the display image data onto the display image. The image processing unit 20 can acquire distance information to the subject from the input image data or the output of the image sensor 13 at the time of shooting. The image processing unit 20 can detect a subject present in the image data and detect the subject area. The image processing unit 20 can acquire area information such as the position and size of the subject in the image, information on the tilt of the subject, and information on the certainty of the subject.

[0020] The memory control unit 22 controls the A / D converter 15, timing generator 14, image processing unit 20, image display memory 24, D / A converter 21, and memory 25. RAW image data generated through the A / D converter 15 is written to the image display memory 24 or memory 25 via the image processing unit 20 and the memory control unit 22. Alternatively, RAW image data generated through the A / D converter 15 is written to the image display memory 24 or memory 25 via the memory control unit 22 without going through the image processing unit 20. The D / A converter 21 controls the image display memory The display image data stored in the memory 24 and memory 25 is converted into analog signals and supplied to the display unit 23.

[0021] The display unit 23 displays image data and various information for display that has been written to the image display memory 24 and memory 25. The display unit 220 includes a TFT LCD (Thin Film Transistor LCD) and the like. The display unit 23 can realize an electronic viewfinder function that displays live images by sequentially displaying captured image data.

[0022] Memory 25 stores captured still images and moving images. Memory 25 has sufficient storage capacity to store a predetermined number of still images and moving images of a predetermined duration. Memory 25 is also used as a workspace for the system control unit 50.

[0023] The exposure control unit 40 controls the shutter 12, which has an aperture function. The exposure control unit 40 has a flash dimming function by working in conjunction with the flash 44. The distance measuring control unit 41 controls the focusing of the photographic lens 11. The zoom control unit 42 controls the zooming of the photographic lens 11. The barrier control unit 43 controls the operation of the barrier 10, which is a protective member. The flash 44 has an AF assist light projection function and a flash dimming function.

[0024] The system control unit 50 is a control unit consisting of at least one processor and / or at least one circuit. That is, the system control unit 50 may be a processor, a circuit, or a combination of a processor and a circuit. The system control unit 50 controls the entire digital camera 100. The non-volatile memory 51 is an electrically erasable and recordable non-volatile memory. The non-volatile memory 51 is, for example, EEPROM (Electrically Erasable Programmable) (registered trademark).

[0025] The shutter button 60 has a first shutter switch 61 and a second shutter switch 62. The first shutter switch 61 (SW1) turns on during the operation of the shutter button 60, when it is half-pressed (indicating preparation for shooting), and outputs a first shutter switch signal SW1. The system control unit 50 starts shooting preparation processing such as AF processing, AE processing, AWB processing, and EF processing in response to the first shutter switch signal SW1.

[0026] The second shutter switch 62 turns on when the shutter button 60 is fully pressed (shooting instruction), and outputs the second shutter switch signal SW2. The system control unit 50 instructs the start of a series of shooting operations, including exposure processing, development processing, and recording processing, in response to the second shutter switch signal SW2. In the exposure processing, the system control unit 50 writes the signal read from the image sensor 13 to the memory 25 as RAW data via the A / D converter 15 and the memory control unit 22. In the development processing, the system control unit 50 uses the calculation results from the image processing unit 20 and the memory control unit 22 to develop the RAW data written to the memory 25 and writes it to the memory 25 as image data. In the recording processing, the system control unit 50 reads the image data from the memory 25, compresses the image data using the image processing unit 20 and stores it in the memory 25, and then writes the image data to the external recording medium 91 via the card controller 90.

[0027] The control unit 63 includes various buttons and a touch panel. For example, the control unit 63 includes a power button, a menu button, a mode setting switch for setting shooting mode / playback mode / other special shooting modes, directional keys, a set button, and a macro button. Also, for example, the control unit 63 includes a flash setting button, a single shot / continuous shot / self-timer switching button, a menu navigation + (plus) button, a menu navigation - (minus) button, a shooting quality selection button, an exposure compensation button, and a date / time setting button.

[0028] The metadata generation and analysis unit 70, when recording image data to the external recording medium 91, adds various metadata, such as Exif (Exchangeable image file format) information, to the image data based on the information at the time of shooting. Furthermore, when reading image data recorded on the external recording medium 91, the metadata generation and analysis unit 70 analyzes the metadata attached to the image data. Metadata includes, for example, various setting information at the time of shooting, image data information related to the image data, and characteristic information of the subject contained in the image data. When recording moving image data, the metadata generation and analysis unit 70 can also generate and attach metadata to each frame.

[0029] The power supply 80 can be 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, or an AC adapter. The power control unit 81 supplies power from the power supply 80 to each part of the digital camera 100.

[0030] The card controller 90 transmits and receives data to and from an external recording medium 91, such as a memory card. The external recording medium 91 is, for example, a memory card, which records images (still images, videos) taken by the digital camera 100.

[0031] The communication unit 71 has a communication circuit for transmitting and receiving. Specifically, the communication unit 71 may be wireless communication such as Wi-Fi and Bluetooth®, or wired communication such as Ethernet and USB.

[0032] The audio signal input unit 28 has a microphone terminal to which various microphones can be connected. The built-in microphone connected to the audio signal input unit 28 is equipped with a diaphragm that generates an electrical signal in accordance with the amount of change in air vibration, and has the characteristic that the amount of electricity generated changes depending on the direction of the input air vibration, even if the amount of change is the same. The audio signal input unit 28 is capable of accepting digital signal input. The audio signal input unit 28 is an audio input terminal to which devices such as the built-in microphone of the digital camera 100, an external microphone with a 3.5φ terminal, and accessories can be connected. Accessories are external devices that are attached to the digital camera 100 via an accessory shoe. The digital camera 100 has multiple audio input terminals.

[0033] The microphone drive circuit 27 drives the audio signal input unit 28 based on control by the system control unit 50. The signal processing circuit 26 performs A / D conversion of the electrical signal and converts the audio information according to the connection type of the audio signal input unit 28, and performs predetermined signal processing. The signal processing circuit 26 can acquire the input level of the audio data to be recorded after signal processing. The signal processing circuit 26 temporarily stores the processed audio data and the input level of the audio data in the memory 25. The data stored in the memory 25 by the signal processing circuit 26 is used for audio output, level meter display, recording processing, etc. The signal processing circuit 26 includes one or more audio output terminals, the same number as or fewer than the audio input terminals.

[0034] The recording preparation process for shooting with the digital camera 100 will be explained using Figure 2. The recording preparation process shown in Figure 2 is started, for example, when the user sets the digital camera 100 to shooting mode using the mode setting switch on the operation unit 63. When the digital camera 100 is set to shooting mode, the system control unit 50 starts preparing for video recording including audio and operates the microphone drive circuit 27.

[0035] In step S201, the system control unit 50 constructs the signal processing circuit 26 by connecting the audio input terminal (hereinafter referred to as the input terminal) and the audio output terminal (hereinafter referred to as the output terminal). Furthermore, the system control unit 50 updates the input terminals connected to the output terminals when the connection status of devices to each input terminal changes. Input terminals and output terminals The process of determining the combination and constructing the signal processing circuit 26 is called automatic input terminal switching. Details of the automatic input / output terminal switching process will be described later with reference to Figure 3.

[0036] The input terminals for constructing the signal processing circuit 26 are the audio signal input section 28 to which the built-in microphone, external microphone, accessories, etc. are connected. The audio output terminals connected to the input terminals are terminals to which the audio recording channels (recording channel buffers) in the memory 25, external recording media 91, built-in speakers, headphones, etc. are connected.

[0037] The audio channels to be recorded are connected to the output terminals. The audio recording channels (audio recording ch) connected to each connection terminal are treated as a set of two channels, such as CH1 / CH2 and CH3 / CH4. One output terminal is connected to CH1 / CH2, and one output terminal is connected to CH3 / CH4.

[0038] The number of output terminals can be pre-configured by the user using the control unit 63. In the automatic input / output terminal switching process, the type of each input terminal and the priority for determining which output terminal to connect each input terminal to when multiple devices are connected to multiple input terminals can be pre-configured by a program or the like.

[0039] In step S202, the system control unit 50 controls the display content on the selection screen for selecting the input terminal to be configured. On the selection screen, the system control unit 50 displays selectable input terminals based on the combination of input and output terminals (wiring status) determined in step S201. On the selection screen, the user selects the input terminal whose settings they want to change from among the selectable input terminals. The system control unit 50 displays the settings screen corresponding to the input terminal selected by the user. The settings screen displays setting items related to the input terminal selected by the user, allowing the user to configure settings related to the selected input terminal without being aware of the wiring status.

[0040] Figures 3, 4(A), and 4(B) illustrate the details of the automatic input / output terminal switching process in step S201 of Figure 2. The automatic input / output terminal switching process is initiated, for example, when the user changes the shooting mode using the mode setting switch on the operation unit 63. Alternatively, the automatic input / output terminal switching process may be initiated when the connection status of a device to any of the input terminals changes. A change in the connection status of a device to an input terminal includes cases where a device is connected to an input terminal and cases where the connection between an input terminal and a device is disconnected.

[0041] In step S301, the system control unit 50 determines whether the shooting mode is video mode. If the shooting mode is not video mode, the process proceeds to step S318. If the shooting mode is not video mode, i.e., audio recording is not performed, the process proceeds to step S318. In step S318, the system control unit 50 terminates the process shown in Figure 3 without performing automatic switching of input / output terminals. In other words, no settings related to input terminals are made. If the shooting mode is video mode, i.e., audio recording is performed, the process proceeds to step S302.

[0042] In step S302, the system control unit 50 determines whether audio recording is enabled. Even if the shooting mode is video mode, if audio is not added to the video, such as in time-lapse video, or if the setting is not to perform audio recording, audio recording is determined to be disabled.

[0043] If audio recording is enabled, the process proceeds to step S303. The system control unit 50 performs automatic switching of input / output terminals in steps S303 to S317. On the other hand, if audio recording is disabled, the process proceeds to step S318. In step S318, the system control unit 50 terminates the process shown in Figure 3 without performing automatic switching of the input / output terminals.

[0044] In steps S303 and S309, the system control unit 50 determines whether the output terminal setting made by the user matches any of the expected output terminal settings. In the example in Figure 3, the expected output terminal settings are 2-channel recording or 4-channel recording.

[0045] In step S303, if the output terminal setting is 2ch recording, the process proceeds to step S304. If the output terminal setting is not 2ch recording, the process proceeds to step S309. In step S309, if the output terminal setting is 4ch recording, the process proceeds to step S310. If the output terminal setting is not 4ch recording, i.e., does not match the expected output terminal setting, the process proceeds to step S318. In step S318, the system control unit 50 terminates the process shown in Figure 3 without performing automatic switching of the input / output terminals.

[0046] In steps S304 to S308 and S310 to S317, the system control unit 50 determines the connection status with the output terminals based on the connection status of the devices to the input terminals and the pre-set priority of each input terminal. The system control unit 50 electronically connects one or more of the input terminals to each of the multiple input terminals. The determination of the connection status between input and output terminals in the automatic input / output terminal switching process in Figure 3 will be explained using Figures 4(A) and 4(B).

[0047] Figures 4(A) and 4(B) illustrate the combinations of input and output terminals according to the connection status of the input terminals in the automatic input / output terminal switching process of Figure 3. In the examples of Figures 4(A) and 4(B), the digital camera 100 has three input terminals to which the built-in microphone 401, an external microphone 402, and an accessory 403 are connected, respectively. In Figure 4(A), the digital camera 100 is set to 2ch recording 404, and the output terminals are CH1 / CH2 and CH3 / CH4. In Figure 4(B), the digital camera 100 is set to 4ch recording 405, and the output terminals are CH1 / CH2 and CH3 / CH4.

[0048] Which of the three input terminals is connected to output terminals CH1 / CH2 and output terminals CH3 / CH4 is determined, for example, based on the priority set for the input terminals. In the examples in Figures 4(A) and 4(B), the priority of the input terminals, from highest to lowest, is the input terminal to which accessory 403 is connected, the input terminal to which external microphone 402 is connected, and the input terminal to which built-in microphone 401 is connected. In the example in Figure 3, it is assumed that the priority of the input terminals does not change depending on the connected device.

[0049] For example, in Figure 4(A), if the built-in microphone 401 is connected to one of the three input terminals, the input terminal connected to the output terminals CH1 / CH2 (hereinafter referred to as output terminals CH1 / CH2) is the input terminal of the built-in microphone 401. Also, if the built-in microphone 401, external microphone 402, and accessory 403 are connected to the three input terminals respectively, the input terminal connected to output terminals CH1 / CH2 will be the input terminal of the accessory 403, which has the highest priority.

[0050] In Figure 4(B), when the built-in microphone 401 is connected to one of the three input terminals, the input terminals connected to the output terminals CH1 / CH2 and CH3 / CH4 (hereinafter referred to as output terminals CH3 / CH4) are all the input terminals of the built-in microphone 401. When the built-in microphone 401, external microphone 402, and accessory 403 are connected to the three input terminals respectively, the input terminal connected to output terminals CH1 / CH2 will be the input terminal of the accessory 403, which has the highest priority. In this case, the output terminals CH3 / CH4 are connected. The input terminal to be used will be the input terminal for external microphone 402, which has the second highest priority.

[0051] In step S304, the system control unit 50 determines whether or not an accessory is connected to the input terminal. If an accessory is connected to the input terminal, the process proceeds to step S305. If an accessory is not connected to the input terminal, the process proceeds to step S306.

[0052] In step S305, the system control unit 50 connects the accessory's input terminal to the output terminals CH1 / CH2. That is, if the accessory is connected to the input terminal with the highest priority, the system control unit 50 connects the input terminal to which the accessory is connected to the output terminals CH1 / CH2.

[0053] In step S306, the system control unit 50 determines whether an external microphone is connected to the input terminal. If an external microphone is connected to the input terminal, the process proceeds to step S307. If an external microphone is not connected to the input terminal, the process proceeds to step S308.

[0054] In step S307, the system control unit 50 connects the input terminal of the external microphone to the output terminals CH1 / CH2. That is, since no accessory is connected to the input terminal with the highest priority, and the external microphone is connected to the input terminal with the second highest priority, the system control unit 50 connects the input terminal to which the external microphone is connected to the output terminals CH1 / CH2.

[0055] In step S308, the system control unit 50 connects the input terminal of the built-in microphone to the output terminals CH1 / CH2. That is, since no accessories or external microphones are connected to input terminals with a higher priority than the input terminal of the built-in microphone, the system control unit 50 connects the input terminal to which the built-in microphone is connected to the output terminals CH1 / CH2.

[0056] Through the processing in steps S304 to S308, the system control unit 50 can determine the combination of input and output terminals as shown in Figure 4(A). When the digital camera 100 is set to 2ch recording 404, the input terminal connected to the output terminals CH1 / CH2 is determined to be one, regardless of the connection status of each input terminal.

[0057] Figure 5 illustrates the settings screen when input and output terminals are connected one-to-one. By determining that only one input terminal is connected to output terminals CH1 / CH2, the user can change the settings related to the input terminal and the output terminal to which that input terminal is connected without having to be aware of the connection status of the input and output terminals.

[0058] Specifically, when the user selects "Recording Settings" on the recording menu screen 501 in Figure 5, the system control unit 50 displays the recording settings screen 502. The recording settings screen 502 displays settings related to the input terminal (wind cut, audio noise reduction) and settings related to the output terminal (recording mode, recording level) on a single screen. Since the recording settings screen 502 displays the items to be set, the user can configure settings related to the processing and functions executed in the signal processing circuit 26 without having to be aware of the wiring status of the input and output terminals.

[0059] In step S309, the system control unit 50 determines whether the output terminal setting is for 4-channel recording. If the output terminal setting is for 4-channel recording, the system control unit 50 determines and connects the input terminals for each of the output terminals CH1 / CH2 and CH3 / CH4. If the output terminal setting is for 4-channel recording, the process proceeds to step S310. If the output terminal setting is not for 4-channel recording, the process proceeds to step S318.

[0060] In step S318, the system control unit 50 terminates the process shown in Figure 3 without performing automatic switching of input / output terminals. In the example shown in Figure 3, the output terminal settings are assumed to be 2-channel recording or 4-channel recording, but are not limited to these. For example, if there are three output terminals, the system control unit 50 can determine which input terminal to connect to each output terminal based on the priority of the input terminals.

[0061] In step S310, the system control unit 50 determines whether or not an accessory is connected to the input terminal. If an accessory is connected to the input terminal, the process proceeds to step S311. If an accessory is not connected to the input terminal, the process proceeds to step S315.

[0062] In step S311, the system control unit 50 connects the accessory's input terminal to the output terminals CH1 / CH2. That is, if the accessory is connected to the input terminal with the highest priority, the system control unit 50 connects the input terminal to which the accessory is connected to the output terminals CH1 / CH2. Once the accessory's input terminal is connected to the output terminals CH1 / CH2, the system control unit 50 determines which input terminal to connect to the output terminals CH3 / CH4 next.

[0063] In step S312, the system control unit 50 determines whether an external microphone is connected to the input terminal. If an external microphone is connected to the input terminal, the process proceeds to step S313. If an external microphone is not connected to the input terminal, the process proceeds to step S314.

[0064] In step S313, the system control unit 50 connects the input terminal of the external microphone to the output terminals CH3 / CH4. That is, since the input terminal of the accessory with the highest priority is connected to the output terminals CH1 / CH2, and the external microphone is connected to the input terminal with the second highest priority, the system control unit 50 connects the input terminal to which the external microphone is connected to the output terminals CH3 / CH4.

[0065] In step S314, the system control unit 50 connects the built-in microphone to output terminals CH3 / CH4 because no external microphone is connected to the input terminal.

[0066] In step S315, the system control unit 50 determines whether an external microphone is connected to the input terminal. If an external microphone is connected to the input terminal, the process proceeds to step S316. If an external microphone is not connected to the input terminal, the process proceeds to step S317.

[0067] In step S316, the system control unit 50 connects the input terminal of the external microphone to the output terminals CH1 / CH2. That is, since no accessory is connected to the input terminal with the highest priority, and the external microphone is connected to the input terminal with the second highest priority, the system control unit 50 connects the input terminal to which the external microphone is connected to the output terminals CH1 / CH2.

[0068] In step S314, the system control unit 50 connects the input terminal of the built-in microphone to the output terminals CH3 / CH4. That is, the input terminal with the highest priority has no accessories connected to it, and the input terminal of the external microphone, which has the second highest priority, is connected to the output terminals CH1 / CH2. For this reason, the system control unit 50 connects the input terminal to which the built-in microphone is connected to the output terminals CH3 / CH4.

[0069] In step S317, the system control unit 50 connects the input terminal of the built-in microphone to the output terminals CH1 / CH2. In step S314, the system control unit 50 also connects the input terminal of the built-in microphone to the output terminals CH3 / CH4.

[0070] Through the processing in steps S310 to S317, the system control unit 50 can determine the combination of input and output terminals as shown in Figure 4(B). When the digital camera 100 is set to 4ch recording 405, the input terminals connected to each of the output terminals CH1 / CH2 and output terminals CH3 / CH4 are determined to be one, regardless of the connection status of each input terminal.

[0071] When the output terminal of the digital camera 100 is set to 4ch recording 405, each of the multiple output terminals (CH1 / CH2, CH3 / CH4) is electronically connected to one of the multiple input terminals (built-in microphone, external microphone, accessory input terminal). In this case, the recording settings screen 502 in Figure 5 has setting items related to multiple input terminals and multiple output terminals. If all settings are displayed on a single screen, the setup process becomes complicated. Furthermore, it becomes difficult to ensure sufficient space for displaying all the setting items. Therefore, before transitioning to the recording settings screen 502, the digital camera 100 displays a selection screen for selecting the input terminal to be configured.

[0072] Figure 6 illustrates the selection screen for selecting the input terminal to be configured. The recording menu screen 601 shows the menu before transitioning to the recording settings. When the user selects "Recording Settings" using the operation unit 63, the system control unit 50 displays the setting target selection screen 602.

[0073] The setting target selection screen 602 displays the expected input terminal options. On the setting target selection screen 602, input terminals that are connected to output terminals and are subject to setting changes are displayed differently from input terminals that are not connected to output terminals and are not subject to setting changes. Input terminals connected to output terminals are displayed as selectable, while input terminals not connected to output terminals are displayed in gray. In the example in Figure 6, "Built-in microphone" and "Accessory" are displayed as selectable, while "External microphone" is displayed in a grayed-out state.

[0074] When the user selects "Built-in Microphone" on the setting target selection screen 602, the system control unit 50 displays a recording settings screen 603 for configuring settings related to the processing and functions performed in the signal processing circuit 26. On the recording settings screen 603, the user can configure specific recording settings for the input terminal to which the built-in microphone is connected, and specific recording settings for the output terminal connected to the input terminal of the built-in microphone. In this way, the system control unit 50 displays a recording settings screen 603 for configuring settings related to the input terminal selected on the setting target selection screen 602 and the output terminal connected to that input terminal.

[0075] Figures 7(A) to 7(F) show examples of selection screens for selecting the input terminal to be configured. Figure 7(A) shows the configuration target selection screen 701 corresponding to combination 406 in Figure 4(A) where output terminals CH1 / CH2 are connected to the input terminals of the built-in microphone. In combination 406, the items related to the built-in microphone connected to the output terminals are the configuration targets, so the configuration target selection screen 701 displays "Built-in Microphone" as a selectable option. Also, since no external microphone or accessories are connected, the "External Microphone" and "Accessories" displays are grayed out. Therefore, the user can easily understand that "External Microphone" and "Accessories" cannot be selected as configuration targets on the configuration target selection screen 701.

[0076] Figure 7(B) shows the setting target selection screen 702 corresponding to combination 407 in Figure 4(A) where output terminals CH1 / CH2 are connected to the input terminal of an external microphone. The setting target selection screen 702 displays "External Microphone" as selectable, and also shows "Built-in Microphone" and "Accessories" The option "" will be displayed in gray.

[0077] Figure 7(C) shows the setting target selection screen 703 corresponding to combination 408 in Figure 4(A) where output terminals CH1 / CH2 are connected to the accessory input terminal. The setting target selection screen 703 displays "Accessories" as selectable, while "Built-in Microphone" and "External Microphone" are grayed out.

[0078] Figure 7(A) shows the setting target selection screen 701 corresponding to combination 409 in Figure 4(B), where both output terminals CH1 / CH2 and output terminals CH3 / CH4 are connected to the input terminals of the built-in microphone. In combination 409, the items related to the built-in microphone connected to the two output terminals are the setting targets, so the setting target selection screen 701 displays "Built-in Microphone" as selectable, while "External Microphone" and "Accessories" are grayed out.

[0079] Figure 7(D) shows the setting target selection screen 704 corresponding to combination 410 in Figure 4(B), where output terminals CH1 / CH2 are connected to the input terminals of an external microphone, and output terminals CH3 / CH4 are connected to the input terminals of the built-in microphone. The setting target selection screen 704 displays "Built-in microphone" and "External microphone" as selectable options, while "Accessories" is grayed out.

[0080] Figure 7(E) shows the setting target selection screen 705 corresponding to combination 411 in Figure 4(B), where output terminals CH1 / CH2 are connected to the accessory input terminal and output terminals CH3 / CH4 are connected to the built-in microphone input terminal. The setting target selection screen 705 displays "Built-in Microphone" and "Accessory" as selectable options, while "External Microphone" is grayed out.

[0081] Figure 7(F) shows the setting target selection screen 706 corresponding to combination 412 in Figure 4(B), where output terminals CH1 / CH2 are connected to the accessory input terminal and output terminals CH3 / CH4 are connected to the external microphone input terminal. The setting target selection screen 706 displays "External Microphone" and "Accessory" as selectable options, while "Built-in Microphone" is grayed out.

[0082] Figures 8(A) to 8(C) show examples of setting screens for input terminals and their corresponding output terminals. Figure 8(A) shows recording setting screen 801, which is displayed when the user selects "Built-in microphone" on setting target selection screens 701, 704, and 705. Figure 8(B) shows recording setting screen 802, which is displayed when the user selects "External microphone" on setting target selection screens 702, 704, and 706. Figure 8(C) shows recording setting screen 803, which is displayed when the user selects "Accessories" on setting target selection screens 703, 705, and 706.

[0083] The recording settings screens 801-803 are used to configure settings related to the input terminal selected by the user on the setting target selection screens 701-706, and settings related to the output terminal to which that input terminal is connected. The recording settings screens 801-803 can display the sound pressure level of the output terminal via the level meter 804, which corresponds to the output terminal to which the input terminal is connected. The user can adjust the sound pressure level of the output terminal while checking it on the level meter 804.

[0084] The recording settings screens 801-803 display the settings for the input terminal selected by the user and the settings for the output terminal to which that input terminal is connected, all on a single screen. This allows the user to configure recording settings for input and output terminals without having to be aware of the connection status. Only the items that can be configured are displayed, and items that cannot be configured are not displayed, thus limiting the display area on the recording settings screens 801-803.

[0085] In the setting target selection screens 701 to 706, input terminals connected to output terminals are displayed as selectable, while input terminals not connected to output terminals are grayed out, allowing the user to easily identify the input terminal to be configured. For example, in the recording setting screen 801, the recording level cannot be set for audio from the built-in microphone, so the recording level item is grayed out. Therefore, the user can easily recognize that the recording level cannot be set. After the user has configured settings for each process and function in each recording setting screen shown in Figure 8, they can instruct the operation unit 63 to configure the settings, and the settings for each function configured on the recording setting screen will be reflected in the processing of the audio signal.

[0086] Using Figure 9, the details of the control process for the input terminal selection screen (setting target selection screens 701-706) in step S202 of Figure 2 will be explained. The control process for the input terminal selection screen is started, for example, when the connection status of a device to any of the input terminals changes. That is, when the input terminal connected to any of the output terminals is updated due to a change in the connection status of a device, the system control unit 50 updates the input terminals that are displayed as selectable on the selection screen by executing the process shown in Figure 9.

[0087] In step S901, the system control unit 50 determines whether the digital camera 100 is set to record audio. The system control unit 50 can determine whether to record audio based, for example, whether it is in video recording mode or whether the setting to record audio is turned on. If the camera is set to record audio, the process proceeds to step S902. If the camera is not set to record audio, the process proceeds to step S914.

[0088] In steps S902 to S913, the system control unit 50 determines whether or not to display each input terminal as selectable on the input terminal selection screen and controls the display of the selection screen. Figure 9 shows an example of processing when the digital camera 100 has three input terminals for connecting a built-in microphone, an external microphone, and an accessory.

[0089] In step S902, the system control unit 50 determines whether the output terminals CH1 / CH2 are connected to the input terminals of the built-in microphone (i.e., whether they are connected to the built-in microphone). If the output terminals CH1 / CH2 are connected to the input terminals of the built-in microphone, the process proceeds to step S903. If the output terminals CH1 / CH2 are not connected to the input terminals of the built-in microphone, the process proceeds to step S904. In step S903, the system control unit 50 displays "Built-in Microphone" as a selectable option on the input terminal selection screen.

[0090] In step S904, the system control unit 50 determines whether output terminals CH3 / CH4 are connected to the input terminals of the built-in microphone (i.e., whether they are connected to the built-in microphone). If output terminals CH3 / CH4 are connected to the input terminals of the built-in microphone, the process proceeds to step S903. If output terminals CH3 / CH4 are not connected to the input terminals of the built-in microphone, the process proceeds to step S905. In step S903, the system control unit 50 displays the "Built-in Microphone" item as selectable on the input terminal selection screen.

[0091] In step S905, the system control unit 50 grays out the "Built-in Microphone" item on the input terminal selection screen. The system control unit 50 may also hide the "Built-in Microphone" item.

[0092] In step S906, the system control unit 50 determines whether the output terminals CH1 / CH2 are connected to the input terminals of an external microphone (i.e., whether they are connected to an external microphone). If the output terminals CH1 / CH2 are connected to the input terminals of an external microphone, the process proceeds to step S907. If the output terminals CH1 / CH2 are not connected to the input terminals of an external microphone, The process proceeds to step S908. In step S907, the system control unit 50 displays the "External Microphone" option as selectable on the input terminal selection screen.

[0093] In step S908, the system control unit 50 determines whether output terminals CH3 / CH4 are connected to the input terminals of an external microphone (i.e., whether they are connected to an external microphone). If output terminals CH3 / CH4 are connected to the input terminals of an external microphone, the process proceeds to step S907. If output terminals CH3 / CH4 are not connected to the input terminals of an external microphone, the process proceeds to step S909. In step S907, the system control unit 50 displays the "External Microphone" item as selectable on the input terminal selection screen.

[0094] In step S909, the system control unit 50 grays out the "External Microphone" item on the input terminal selection screen. The system control unit 50 may also hide the "External Microphone" item.

[0095] In step S910, the system control unit 50 determines whether the output terminals CH1 / CH2 are connected to the accessory input terminals (i.e., whether they are connected to an accessory). If the output terminals CH1 / CH2 are connected to the accessory input terminals, the process proceeds to step S911. If the output terminals CH1 / CH2 are not connected to the accessory input terminals, the process proceeds to step S912. In step S911, the system control unit 50 displays the "Accessory" item as selectable on the input terminal selection screen.

[0096] In step S912, the system control unit 50 determines whether the output terminals CH3 / CH4 are connected to the accessory input terminals (i.e., whether they are connected to an accessory). If the output terminals CH3 / CH4 are connected to the accessory input terminals, the process proceeds to step S911. If the output terminals CH3 / CH4 are not connected to the accessory input terminals, the process proceeds to step S913. In step S911, the system control unit 50 displays the "Accessory" item as selectable on the input terminal selection screen.

[0097] In step S913, the system control unit 50 grays out the "Accessories" item on the input terminal selection screen. The system control unit 50 may also hide the "Accessories" item.

[0098] As a result of the processing in steps S902 to S913, input terminals that have been updated from an unconnected state to a connected state will be displayed as selectable on the selection screen. In addition, input terminals that have been updated from an connected state to an unconnected state will be controlled so that they cannot be selected on the selection screen (they will be hidden or grayed out).

[0099] Steps S914 to S916 are the processes to be performed when the digital camera 100 does not record. In step S914, the system control unit 50 grays out the "Built-in Microphone" item on the input terminal selection screen. The system control unit 50 may also hide the "Built-in Microphone" item. In step S915, the system control unit 50 grays out the "External Microphone" item on the input terminal selection screen. The system control unit 50 may also hide the "External Microphone" item. In step S916, the system control unit 50 grays out the "Accessories" item on the input terminal selection screen. The system control unit 50 may also hide the "Accessories" item.

[0100] Furthermore, the system control unit 50 may control the selection screen so that the input terminal cannot be selected if the settings related to the input terminal connected to the output terminal are made on the device connected to that input terminal. For example, in step S910, output terminal CH1 / CH Even if an accessory input terminal is connected to terminal 2, if settings are made on the device (accessory) side, the system may be controlled so that "Accessory" is not selected on the selection screen. Whether or not to control the selection of an input terminal connected to an output terminal can be set in advance, for example, based on the type of input terminal or the type of device connected to the input terminal. The system control unit 50 can determine whether or not to control the selection of an input terminal connected to an output terminal based on the type of input terminal or the type of device connected to the input terminal.

[0101] In the above embodiment, the digital camera 100 automatically switches the connection status of the input and output terminals in response to changes in the connection status of the input terminals. The digital camera 100 also displays a settings screen for changing settings related to the input terminals and the output terminals to which those input terminals are connected. Even if the user is unaware of the connection status between the input and output terminals, they can easily change the settings related to the input terminals connected to the output terminals.

[0102] Furthermore, the various controls described above, which are performed by the system control unit 50, may or may not be performed by a single piece of hardware (e.g., a processor or circuit). Multiple pieces of hardware (e.g., multiple processors, multiple circuits, or a combination of one or more processors and one or more circuits) may share the processing to control the entire device.
