(Configuration of one embodiment)
First, the configuration of the imaging apparatus 100 according to an embodiment of the present invention will be described. FIG. 1 is a block diagram illustrating a configuration of an imaging apparatus 100 according to the present embodiment. The imaging device 100 is a digital still camera, for example, and can capture a still image.

  The imaging apparatus 100 according to the present embodiment includes, for example, an optical block 101, a driving unit 102, an imaging element 103, an analog processing circuit 104, an image processing unit 105, an MPU 110, a ROM 121, a RAM 122, and an operation input. I / F 123, operation input unit 124, display control unit 125, display unit 126, memory card I / F 127, memory card 128, external input / output I / F 129, GPS communication unit 130, and wireless communication Part 140 and the like.

  The optical block 101 includes, for example, a zoom lens, a diaphragm, and a focus lens. The optical block 101 is an optical system that forms an image of external light information on the image sensor 103, and transmits light from the subject to the image sensor 103. The zoom lens is a lens that changes the angle of view by changing the focal length. The diaphragm is a mechanism that adjusts the amount of light that is transmitted, and is driven by a zoom lens motor. The focus lens moves in the optical axis direction to focus the subject image on the imaging surface of the imaging element 103. The focus lens is driven by a focus lens motor. Each motor receives a drive signal from the drive unit 102 and is driven.

  The image sensor 103 is an example of a photoelectric conversion element, and includes a plurality of elements that can perform photoelectric conversion that converts optical information that has passed through the optical block 101 and entered into an electrical signal. Each element generates an electrical signal corresponding to the received light. As the image sensor 103, a CCD (charge coupled device) sensor, a CMOS (complementary metal oxide semiconductor) sensor, or the like can be applied.

  Note that in order to control the exposure time of the image sensor 103, a mechanical shutter (not shown) can be applied so that the light is blocked during non-shooting and the light is applied only during shooting. Further, the present invention is not limited to this, and an electronic shutter (not shown) may be applied. The mechanical shutter or the electronic shutter is operated by a switch of a shutter button (operation input unit 124).

  The analog processing circuit 104 includes, for example, a CDS / AMP unit, an A / D conversion unit, and an image input controller. The CDS / AMP unit (correlated double sampling circuit / amplifier) removes low-frequency noise contained in the electric signal output from the image sensor 103 and brings the electric signal to an arbitrary level. Amplify. The A / D conversion unit digitally converts the electrical signal output from the CDS / AMP unit to generate a digital signal. The A / D conversion unit outputs the generated digital signal to the image input controller.

  The image input controller performs processing on the digital signal output from the A / D conversion unit to generate an image signal that can be processed. The image input controller outputs the generated image signal to the image processing unit 105, for example. The image input controller controls reading / writing of image data to / from the RAM 122.

  The image processing unit 105 receives an image signal from the image input controller, and generates an image signal subjected to image processing based on a WB control value, a γ value, a contour enhancement control value, and the like. The image processing unit 105 calculates an AE evaluation value and an AF evaluation value based on the image signal and sends them to the MPU 110.

  The image processing unit 105 may perform compression processing, receives an image signal before compression processing, and compresses the image signal in a compression format such as a JPEG compression format or an LZW compression format. The image processing unit 105 sends the image data generated by the compression process to, for example, a memory card I / F.

  The MPU 110 functions as an arithmetic processing device and a control device according to a program recorded in the ROM 121, for example, and controls processing of each component provided in the imaging device 100. The MPU 110 drives the optical block 101 by outputting a signal to the drive unit 102 based on, for example, focus control or exposure control. Further, the MPU 110 controls each component of the imaging device 100 based on a signal from the operation input unit 124. In this embodiment, only one MPU 110 is used. However, the MPU 110 may be configured by a plurality of MPUs such as a separate MPU for signal-related commands and operation-related commands.

  The MPU 110 includes, for example, a timing generator, a proper AWB calculation unit, a video AF control unit, a focus control unit, an AE control unit, an aperture control unit, an image processing selection unit, a GUI management unit, and the like.

  The timing generator outputs a timing signal to the image sensor 103 and the CDS / AMP unit, and controls the exposure period of each pixel constituting the image sensor 103 and the charge readout control.

  The appropriate AWB calculation unit calculates the WB control value based on the color information of the image signal corresponding to the subject image received by the image sensor 103. For example, the appropriate AWB calculation unit calculates the WB control value so that an appropriate white balance (WB) corresponding to the subject is obtained. The appropriate AWB calculation unit sends the calculated WB control value to the image processing unit 105.

  The video AF control unit calculates the focus position of the focus lens based on the AF (auto focus) evaluation value calculated by the image processing unit 105. The AF evaluation value is calculated by the image processing unit 105 based on the luminance value of the image signal. The AF evaluation value is, for example, a contrast value of an image. When the contrast value reaches a peak, it is determined that the subject image is in focus on the imaging surface of the image sensor 103 (contrast detection method).

  Upon receiving the focus control start operation signal, the focus control unit generates a control signal for moving the focus lens in one direction, and outputs the generated control signal to the drive unit 102. The drive unit 102 generates a drive signal based on the control signal received from the focus control unit. The drive unit 102 sends the generated drive signal to the motor. The drive unit 102 drives the focus lens in the optical axis direction during focus control.

  Based on the AE (auto exposure) evaluation value calculated by the image processing unit 105, the AE control unit calculates the aperture amount of the aperture and the shutter speed. The AE evaluation value is calculated by the image processing unit 105 based on the luminance value of the image signal. The AE control unit outputs the aperture amount obtained as a result of the calculation to the aperture control unit.

  The aperture control unit outputs the acquired aperture amount to the drive unit 102 as a control signal. The aperture control unit controls the amount of light based on the aperture value used for the actual shooting at the time of shooting. The drive unit 102 generates a drive signal based on the control signal received from the aperture control unit. The drive unit 102 sends the generated drive signal to the motor.

  The image processing selection unit selects whether or not to perform image processing such as gamma correction and contour enhancement processing on the image signal, and sets parameters necessary for each image processing. The image processing selection unit sends the selection result and the set parameters to the image processing unit 105.

  The GUI management unit manages a GUI (graphic user interface) such as a thumbnail screen of images displayed on the display unit 126 and a menu screen for operating the imaging apparatus 100. For example, the GUI management unit receives an operation signal from the operation input unit 124 and sends a control signal based on the operation signal to the display control unit 125.

  The RAM 122 is, for example, an SDRAM (synchronous DRAM), and temporarily stores image data of captured images. The RAM 122 has a storage capacity capable of storing image data of a plurality of images. The RAM 122 sequentially holds image signals at the time of focus control and outputs image signals. The RAM 122 stores an operation program for the MPU 110. Reading and writing of images to and from the RAM 122 is controlled by an image input controller.

  The operation input unit 124 is, for example, an up / down / left / right key, a power switch, a mode dial, or a shutter button provided in the imaging apparatus 100. The operation input unit 124 sends an operation signal to the MPU 110 or the like via the operation input I / F 123 based on an operation by the user. For example, the shutter button can be half pressed, fully pressed, or released by the user. When the shutter button is half-pressed (S1 operation), an operation signal for starting focus control is output, and when half-pressed, the focus control is finished. In addition, when the shutter button is fully pressed (S2 operation), an operation signal for starting shooting is output.

  The display control unit 125 receives image data from, for example, a VRAM and displays an image on a display unit 126 such as an LCD (liquid crystal display) or an organic EL display. The display unit 126 is provided in the main body of the imaging device 100. The image displayed by the display unit 126 is, for example, an image before shooting (live view display) read from the VRAM, various setting screens of the imaging device 100, images captured and recorded, and the like.

  VRAM (video RAM) is a memory for image display and has a plurality of channels. The VRAM can simultaneously input image data for image display from the RAM 122 and output image data to the display control unit 125. The resolution and the maximum number of colors of the display unit 126 depend on the capacity of the VRAM.

  The memory card I / F 127 controls writing of image data to the memory card 128 or reading of image data and setting information recorded on the memory card 128. The memory card 128 is a magnetic disk, a semiconductor storage medium, or the like, and records captured image data. Note that the present embodiment is not limited to a memory card, and may be, for example, an optical disc (CD, DVD, Blu-ray disc, etc.), a magneto-optical disc, or the like. The memory card 128 may be configured to be detachable from the imaging device 100.

  The external input / output I / F 129 is, for example, a USB terminal, an IEEE 1394 terminal, or the like, and is an interface that can be connected to an external device. Various types of data are input to the information processing apparatus 100 via the external input / output I / F 129.

  The GPS communication unit 130 receives radio waves from GPS satellites and acquires position information of the current position. Here, the position information is, for example, latitude, longitude, altitude, etc. of the current position.

  The wireless communication unit 140 connects to a wireless LAN access point, receives data from a network such as the Internet, and transmits data to the network. In this embodiment, a case where wireless is used as a means connected to the network will be described. However, the present invention is not limited to this, and the imaging apparatus 100 and the network may be connected by wire.

  In addition, the MPU 110 includes a position information acquisition unit, a time information acquisition unit, an imaging condition information acquisition unit, and a parameter determination unit. The position information acquisition unit acquires position information regarding the shooting position received by the GPS communication unit 130 or the wireless communication unit 140 before the main shooting. The time information acquisition unit acquires time information related to the shooting time received by the GPS communication unit 130 or the wireless communication unit 140 or the time information included in the clock provided in the main body of the imaging device 100 before the main shooting.

  The imaging condition information acquisition unit acquires imaging condition information before actual imaging based on at least one of position information and time information. For example, the imaging condition information acquisition unit transmits at least one of position information and time information to an external server device via the wireless communication unit 140 and the network, and acquires the imaging condition information from the server device.

  The parameter determination unit determines one or a plurality of shooting parameters set at the time of actual shooting based on the shooting condition information.

  The parameter determination unit includes a holding unit, a determination unit, a selection unit, and a parameter extraction unit. The holding unit holds a plurality of pre-registered scene modes composed of combinations of a plurality of shooting parameters. The determination unit determines whether or not there is a corresponding scene mode among a plurality of scene modes with respect to at least one of position information, time information, and shooting condition information. When the selection unit determines that there is a corresponding scene mode, the selection unit selects the corresponding scene mode and determines a shooting parameter. In addition, when the parameter extraction unit determines that there is no corresponding scene mode, the parameter extraction unit extracts a shooting parameter based on at least one of position information, time information, and shooting condition information without depending on the scene mode.

  Note that a series of processing in the imaging apparatus 100 may be processed by hardware or may be realized by software processing by a program on a computer.

(Operation of one embodiment)
Next, the operation of the imaging apparatus 100 according to the present embodiment will be described with reference to FIG. FIG. 2 is a flowchart showing the operation of the imaging apparatus according to the present embodiment.

  First, when the power of the imaging device 100 is turned on, communication by GPS or wireless LAN (both depending on the setting) is started before the actual photographing (steps S101 and S102). Then, information that can be acquired is received by the GPS or the wireless LAN, and the information is taken into the imaging apparatus 100 (steps S103 and S104). For example, information that can be acquired by GPS is position information (for example, latitude, longitude, etc.) and date / time information.

  The information that can be acquired by the wireless LAN is, for example, information obtained when the imaging apparatus 100 accesses a specific server or an unspecified server connected to a network such as the Internet. For example, position information (a floor in a building, a specific area, etc.), date information (date information, time information), weather information, store information, peripheral facility information, event information, and the like. Weather information, store information, peripheral facility information, and event information are examples of shooting condition information. In order to acquire weather information, store information, peripheral facility information, and event information, when the imaging apparatus 100 accesses the server, the imaging apparatus 100 transmits position information, date and time information, and the like.

  Next, each information is analyzed based on the information which the imaging device 100 acquired. For example, position information obtained by a LAN access point or the like of GPS or wireless LAN is analyzed (step S105). Thereby, it is possible to determine a place where the photographer performs the photographing. Further, the date and time information obtained by the GPS, the wireless LAN, or the clock built in the imaging apparatus 100 is analyzed (step S106). Thereby, it is possible to determine the date and time when the photographer performs photographing.

  Further, the weather information obtained by the wireless LAN is analyzed (step S107). This makes it possible to determine the brightness and color of the shooting location when the shooting location is outdoors or when indoors, such as when the window is open.

  Further, based on the position information obtained by GPS or wireless LAN and the peripheral facility information, it is analyzed whether the shooting location is indoor or outdoor (step S108). At this time, accompanying information such as peripheral facility (building) information and store information obtained by GPS or wireless LAN is also analyzed (step S109).

  If the indoor / outdoor analysis determines that it is outdoors, the assumed intensity of sunlight is determined based on the date information and weather information. On the other hand, if it is determined to be indoor, the brightness of the indoor light is determined from the surrounding facility information assuming the indoor brightness according to the facility. At this time, the determined sunlight or indoor brightness may be one or a plurality of different brightnesses.

  Next, based on the analysis result described above, the scene mode or shooting parameter of the imaging device 100 to be set at the time of shooting is determined (step S110). For example, it is determined whether or not shooting conditions such as a shooting location and a shooting date and time obtained from the analysis result appropriately match a scene mode registered in advance in the imaging apparatus 100 (step S111). If it is determined that the scene mode is met, the scene mode is selected so that shooting can be performed in the scene mode (step S112). On the other hand, if it is determined that the scene mode does not match, shooting parameter candidates suitable for shooting are extracted based on position information, date information, peripheral facility information, and the like (step S113). One or more imaging parameter candidates may be extracted. The shooting parameters are parameters that can adjust shooting conditions at the time of actual shooting, for example, and include ISO speed, white balance adjustment value, exposure amount, and the like.

  Next, when selecting a parameter before the main shooting, a sample preview showing what kind of image the shooting result will be when the main shooting is performed with the shooting parameters as candidates is displayed on the display 126 (display). Step S114). When a plurality of scene modes and a plurality of shooting parameter candidates are selected, for example, when the user requests a preview display, a plurality of sample images corresponding to the assumed scene mode and shooting parameter settings are displayed. Then, when the user selects one image from the sample images, shooting parameters used for the main shooting are determined, and the shooting parameters are set in the imaging apparatus 100 before the main shooting. When the shutter button is fully pressed, shooting is performed based on the set shooting parameters, and image data is acquired (step S115).

  As described above, the parameters for capturing an image desired by the user are assumed by the imaging apparatus 100 without being operated and selected by the user. Therefore, the user can easily start shooting.

(Information that can be acquired from GPS or wireless LAN)
Next, information that can be acquired by the imaging apparatus 100 from the GPS or the wireless LAN will be described with reference to FIG. FIG. 3 is an explanatory diagram showing information that can be acquired from the GPS or wireless LAN by the imaging apparatus 100 according to the present embodiment.

  Examples of information that can be acquired from the GPS include position information, time information, and date information. Information that can be acquired from the wireless LAN includes, for example, position information, time information, date information, weather information, store information, peripheral facility information, and event information.

  Here, store information is information obtained based on position information. The store information is, for example, floor information in a building, service information provided by the store, and the like. The peripheral facility information is information obtained based on the position information. The peripheral facilities in the peripheral facility information are facilities such as restaurants, gymnasiums, halls, parking lots, and hotels, for example. Event information is information obtained based on position information and date / time information. Events in event information include concerts held in halls (more specifically, classical music concerts, pop music concerts, etc.), bargain information held by stores, sports events held in gymnasiums, stadiums, etc. Fireworks festivals and festivals to be held.

(Scene mode, shooting (adjustment) parameters)
Next, scene modes and shooting (adjustment) parameters that can be set by the imaging apparatus 100 will be described with reference to FIG. FIG. 4 is an explanatory diagram showing scene modes and shooting (adjustment) parameters that can be set by the imaging apparatus 100.

  The scene mode includes a combination of various shooting (adjustment) parameters registered in advance in the imaging apparatus 100 so that an appropriate image can be obtained according to the shooting scene. As shown in FIG. 4A, the scene mode includes, for example, snow, beach, landscape, portrait, child, macro, sunset, dawn, backlight, fireworks, backlight (forced flash), and the like. In the scene mode, various shooting (adjustment) parameters are combined assuming a subject, a shooting location, and a shooting time.

  The shooting (adjustment) parameter is a parameter that can adjust the setting conditions at the time of actual shooting and the image processing conditions at the time of image processing. The shooting (adjustment) parameters include, for example, ISO speed, exposure correction, color balance, sharpness, white balance, noise reduction, red-eye correction, flash intensity, etc., as shown in FIG. 4B.

  In step S111 described with reference to FIG. 2, if the shooting date / time and location match the scene mode registered in advance in the imaging device 100 based on information obtained from GPA or wireless LAN, the matching scene mode Parameter setting can be made. However, the scene mode parameter setting alone may not be sufficient to obtain an appropriate image. Therefore, in the present embodiment, the shooting (adjustment) parameters can be directly set based on the information obtained from the GPA or the wireless LAN, assuming the shooting date and time and the location.

  Next, a specific example when the imaging apparatus 100 of the present embodiment sets parameters will be described. 5 and 6 are explanatory diagrams illustrating the relationship between information acquired by the imaging apparatus 100 and parameters assumed by the imaging apparatus 100. FIG.

  With reference to FIG. 5, for example, a case where the imaging apparatus 100 acquires information “fireworks display” as event information will be described.

  The imaging device 100 determines whether the shooting location is indoor or outdoor based on the acquired position information, peripheral facility information, the distance between the peripheral facility and the imaging device 100, and the like. In the case of a fireworks display, information on the outdoors can be obtained. Further, the imaging device 100 determines whether the shooting location is a location where the event is performed based on the acquired position information, event information, a distance between the location where the event is performed and the imaging device 100, and the like. In the case of the fireworks display, the shooting location is determined to be the venue for the fireworks display. When it is determined that the event information is an event other than a fireworks display, for example, a sports event, selection of a scene mode, which will be described later, is performed according to the sports event. Also, based on the date information, it is determined whether it is a date for the fireworks display.

  Furthermore, the acquired weather information and time information are analyzed, and a scene mode is selected and shooting parameter candidates are extracted according to the shooting scene (shooting scene) assumed by the weather information and time information obtained by the analysis. Or For example, as shown in FIG. 5, if it is sunny and daytime, it is the time zone before the fireworks are launched, so an auto mode or a backlight mode suitable for photographing a person or a landscape is selected. If it is sunny and evening, an auto mode, a backlight mode, and a sunset mode, which are suitable for shooting a person or landscape in the evening, are selected.

Further, if it is sunny and night, fireworks are being launched, so the fireworks mode, auto mode + flash ON, exposure UP + ISO height are selected. The fireworks mode is suitable for photographing the fireworks themselves. The exposure UP + ISO height is suitable for photographing a person during the fireworks launch by increasing the exposure and increasing the ISO speed. Further, noise reduction of the shooting (adjustment) parameter may be increased.
If it is raining or cloudy, for example, exposure UP + ISO height is selected.

  With reference to FIG. 6, for example, a case where the imaging apparatus 100 acquires information “karaoke shop” as peripheral facility information will be described.

  The imaging device 100 determines whether the shooting location is indoor or outdoor based on the acquired position information, peripheral facility information, the distance between the peripheral facility and the imaging device 100, and the like. In the case of a karaoke store, information that is indoors can be obtained. In the case of a karaoke store, the imaging device 100 determines that the shooting location is in the karaoke store.

  At this time, regardless of the weather information, time information, and date information, a scene mode is selected or shooting parameter candidates are extracted according to the shooting scene (shooting scene) in the karaoke store. Since the inside of a karaoke store is often dark, for example, as shown in FIG. 6, an auto mode + flash ON or exposure UP + ISO height suitable for photographing a person in the dark is selected.

  As described above, the imaging apparatus 100 may select a scene mode when there is a matching scene mode, or may adjust various shooting parameters when there is no matching scene mode. For example, when it is assumed that the photographer is not going to shoot the fireworks themselves from outdoor / indoor, weather information, etc., an appropriate combination of shooting parameters as described above can be set. Accordingly, it is possible to provide parameters suitable for shooting for obtaining an appropriate image even for a user who does not have detailed knowledge of the imaging apparatus 100.

  Note that the relationship between the information acquired by the imaging apparatus 100 and the parameters assumed by the imaging apparatus 100 as illustrated in FIGS. 5 and 6 is stored in the memory of the imaging apparatus 100 in advance.
