Description

  The present invention relates to a portable device such as a digital camera or a mobile phone provided with an imaging unit, and more particularly to a portable device that automatically changes a photometric condition according to the attitude of the portable device and performs photometry.

  Examples of camera photometry include center-weighted average photometry, spot photometry, and multi-division photometry (multi-photometry). Center-weighted average metering is a metering method in which the entire screen imaged by the camera is metered so that the sensitivity at the center of the screen is increased. Spot metering is a metering method in which only the center of the screen imaged by the camera is metered. Multi-division photometry (multi-photometry) is a photometry method in which a screen imaged by a camera is divided into a plurality of areas, and photometry is performed so that sensitivity in a specific area of the plurality of areas is increased. Hereinafter, increasing the sensitivity in a specific region is referred to as weighting. The camera takes an image by performing exposure control according to the amount of light measured.

  In addition, with regard to the photometric method, a camera has been proposed that detects whether the photo is taken in the horizontal position or the photo is held in the vertical position, and the photometry method is automatically changed according to the detection result. (For example, refer to Patent Document 1).

  In addition, a mobile wireless terminal that automatically changes the photometry method according to the imaging direction and the imaging angle of view has been proposed (see, for example, Patent Document 2).

Japanese Patent Laid-Open No. 7-168242 (page 2-5, FIG. 1) JP 2002-369073 A (page 2-4, FIG. 7)

  FIG. 7A is a diagram illustrating a case where the camera is photographed in the vertical direction in multi-division photometry (multi-photometry). In FIG. 7, photometry is performed by weighting the shaded portion. That is, exposure control is performed based on the photometric quantity in the shaded area. Usually, when shooting a subject such as a person or a landscape, the user shoots the subject so that the subject is below the center of the screen. The area is not subject to photometry. This is because the peripheral part above the center of the image to be photographed includes light sources other than the subject such as the sun and illumination, so that the influence of these light sources is eliminated and the subject is photographed with an appropriate exposure.

  However, as shown in FIG. 7B, when shooting with the camera in the horizontal direction, the weighted area comes to the side, and appropriate exposure cannot be obtained depending on the shooting environment.

  Here, the camera being in the vertical direction is a direction in which the image captured by the imaging unit is vertically long in a plane orthogonal to the direction in which light from the subject is incident, and the camera is in the horizontal direction. Is a direction in which the image captured by the imaging unit becomes horizontally long in a plane orthogonal to the direction in which light from the subject is incident.

  FIG. 8A shows a case where weighting is performed in consideration of taking a picture in the horizontal direction in multi-division metering (multi-metering). However, as shown in FIG. When the image is taken in this manner, the weighted area comes to the side, and appropriate photometry cannot be performed depending on the shooting environment.

  Also, as described in Patent Document 1, when shooting with the camera in the horizontal position, multi-division metering (multi-metering) suitable for distant shooting is automatically set, and the camera is set in the vertical position. If you set automatically to center-weighted average metering or spot metering suitable for close-up shooting, for example, close-up shooting with the camera in the horizontal position or long-distance shooting with the camera in the vertical position In such a case, appropriate exposure control cannot be performed.

  As described in Patent Document 2, if the photometry method is automatically changed according to the imaging direction and the imaging angle of view, the subject to be photographed is not appropriate for the imaging direction and the imaging angle of view. In this case, appropriate exposure control cannot be performed.

  Accordingly, an object of the present invention is to provide a portable device and a photometric control method for performing appropriate exposure control by changing a weighted photometric area in multi-division metering according to the posture of the portable device.

  The attitude detection means uses one of a plurality of types of signals corresponding to the degree of inclination of the imaging means with reference to a predetermined direction in a plane orthogonal to the direction in which light from the subject is incident as the attitude of the mobile device. The storage means may store photometric conditions corresponding to each of the signals corresponding to the degree of inclination. According to such a configuration, the calculation means can set an appropriate photometric condition according to the attitude of the mobile device.

Alternatively, the storage unit may store the photometric conditions when the mobile device is in the horizontal orientation and the photometric conditions when the mobile device is in the vertical orientation. According to such a configuration, it is possible to perform photometry under appropriate photometric conditions depending on whether the mobile device is in a vertical orientation or a horizontal orientation.

  You may provide the setting input means in which a user inputs photometry conditions. According to such a configuration, the user can input photometric conditions.

  When the metering condition selected by the computing means does not match the metering condition input by the user to the setting input means, the metering condition selected by the computing means is the metering condition input by the user to the setting input means on the display means of the portable device. There may be provided a control means for displaying a warning indicating that they do not match. According to such a configuration, it is possible to notify the user that the photometry condition set by the user does not match the photometry condition selected by the calculation means.

  If the metering condition selected by the computing means and the metering condition input by the user to the setting input means do not match, the metering condition input by the user from the audio output means of the portable device to the setting input means is the metering condition selected by the computing means Control means for outputting a warning sound indicating that they do not match the above may be provided. According to such a configuration, it is possible to notify the user that the photometry condition set by the user does not match the photometry condition selected by the calculation means.

It is characterized by.

  If the metering condition selected according to the attitude of the portable device and the metering condition input by the user do not match, the user may enter the setting input unit. A warning indicating that the input photometric conditions do not match the photometric conditions selected according to the attitude of the mobile device may be displayed. According to such a configuration, it is possible to notify the user that the photometric conditions set by the user do not match the photometric conditions selected according to the attitude of the mobile device.

  The tilt detection unit 106 is realized by, for example, a known tilt sensor, and detects whether the mobile phone 200 is tilted by detecting whether the mobile phone 200 is tilted. When the mobile phone 200 is tilted, for example, an ON signal is output to the camera / display control / image processing unit 104. When the mobile phone 200 is not tilted, for example, an OFF signal is output to the camera / display control / image processing unit 104. To do.

  FIG. 2 is a diagram showing a case where each block constituting the mobile device according to the present invention is built in the mobile phone 200 as an example of the embodiment. The photoelectric conversion unit 102 and the camera DSP unit 103 may be integrated as a camera module or may be separated. As shown by the arrows in FIG. 2, when the mobile phone 200 is tilted, the blocks constituting the mobile device according to the present invention are also tilted. If the mobile phone 200 is in the vertical direction (the state of FIG. 2), the photoelectric conversion unit 102 is also If the mobile phone 200 is in the horizontal direction, the photoelectric conversion unit 102 is also in the horizontal direction. Here, the vertical direction represents the state shown in FIG. 2, and the horizontal direction represents a state inclined by 90 ° in the direction of the arrow shown in FIG. That is, it is provided on the back surface side (the side not visible in FIG. 2) of the upright member of the two members in the structure shown in FIG. 2 in a plane orthogonal to the direction in which the light from the subject is incident. A state in which a user normally sees characters and the like displayed on the display unit 105 is defined as a vertical direction, and a state tilted by 90 ° in the plane is defined as a horizontal direction. The inclination detection unit 106 detects a state inclined 90 degrees in the direction of the arrow shown in FIG. Specifically, the output signal of the tilt detection unit 106 is an OFF signal when the mobile phone 200 is tilted from a vertical position to a horizontal position when tilted by a predetermined angle (for example, 45 °). Changes from ON to ON signal.

  The camera / display control / image processing unit 104 is realized by, for example, an IC (Integrated Circuit), and determines whether the mobile phone 200 is in the vertical direction or the horizontal direction based on the output signal of the tilt sensor. Specifically, when the signal output from the tilt detection unit 106 indicates that the mobile phone 200 is not tilted, it is determined that the mobile phone 200 is in the vertical direction. Further, when the signal output from the tilt detection unit 106 indicates that the mobile phone 200 is tilted, it is determined that the mobile phone 200 is in the horizontal direction. The camera / display control / image processing unit 104 generates camera attitude information that is information specifying whether the mobile phone 200 is in the vertical direction or the mobile phone 200 is in the horizontal direction, for example, I2C (Inter Integrated). It is output to the camera DSP unit 103 connected by a Circuit) interface or the like.

  The camera DSP unit 103 previously stores photometric conditions corresponding to the case where the mobile phone 200 is in the vertical direction and the case where the mobile phone 200 is in the horizontal direction. The camera DSP unit 103 stores, in advance, a photometry condition corresponding to the case where the mobile phone 200 is in the vertical direction and a photometry condition corresponding to the case where the mobile phone 200 is in the horizontal direction. 104 reads out according to the camera posture information output. Specifically, when the camera posture information indicates that the mobile phone 200 is in the vertical direction, the photometry conditions corresponding to the case where the mobile phone 200 is in the vertical direction are read, and the camera posture information is displayed in the mobile phone 200. Indicates that the mobile phone 200 is in the horizontal direction, the photometric conditions corresponding to the case where the mobile phone 200 is in the horizontal direction are read out.

  Here, the photometry condition is a condition for specifying a value for weighting the result of photometry performed on each region of the photoelectric conversion unit 102 that has been divided into regions in advance.

  FIG. 3A is an example illustrating photometric conditions corresponding to the case where the mobile phone 200 is in the vertical direction. FIG. 3B is another example illustrating photometric conditions corresponding to the case where the mobile phone 200 is in the horizontal direction. In FIG. 3 (a) and FIG. 3 (b), each area shown by hatching is weighted. In this embodiment, the weighted area is an area where the amount of light is used for photometry, and the unweighted area is an area not used for photometry. It can also be said that the unweighted region is a region with a weight of zero.

  At the time of photometry, the camera DSP unit 103 performs photometry processing based on the output corresponding to each region in the photoelectric conversion unit 102 and photometry conditions. The photometric process is, for example, a process for obtaining an average light amount of a weighted area indicated by a photometric condition.

  The camera DSP unit 103 calculates the optimum exposure amount of the photoelectric conversion unit 102 based on the result of the photometry process. The camera DSP unit 103 generates exposure specifying information that is information for specifying a gain value, a shutter speed, and the like for the output of the photoelectric conversion element of the photoelectric conversion unit 102 at the time of imaging so that the calculated exposure amount is realized.

  Based on the exposure specifying information, the photoelectric conversion unit 102 receives the light incident from the lens unit 101, and after the exposure control parameters such as the determined gain value and shutter speed are set, the light incident from the lens unit 101 Is subjected to photoelectric conversion to be converted into an electric signal, an electric signal is generated, and image information is output to the camera DSP unit 103. Note that the posture of the photoelectric conversion unit 102 changes as the posture of the mobile device changes. Specifically, when the mobile phone 200 is in the vertical direction, the photoelectric conversion unit 102 is in the vertical direction, and when the mobile phone 200 is in the horizontal direction, the photoelectric conversion unit 102 is in the horizontal direction.

  FIG. 4 is a diagram schematically showing the photoelectric conversion unit 102 and the camera DSP unit 103. As shown in FIG. 4, the range captured by the photoelectric conversion unit 102 varies between the vertical direction and the horizontal direction.

  The camera DSP unit 103 converts the electrical signal output from the photoelectric conversion unit 102 into image information. Then, the camera DSP unit 103 outputs the image information to the camera / display control / image processing unit 104. The camera / display control / image processing unit 104 outputs image information to the display unit 105 to display an image, or performs image processing such as digital zoom.

  Next, the operation of this embodiment will be described with reference to the drawings. FIG. 5 is a flowchart for explaining the operation of this embodiment.

  First, the tilt detection unit 106 detects whether or not the mobile phone 200 is tilted, and outputs the detection result to the camera / display control / image processing unit 104 (step S101). The camera / display control / image processing unit 104 determines whether the camera is tilted based on the output result of the tilt detection unit 106. If the mobile phone 200 is not tilted, the mobile phone 200 is in the vertical direction. The camera attitude information indicating that the mobile phone 200 is in the vertical direction is generated and output to the camera DSP unit 103. When camera posture information indicating that the mobile phone 200 is in the vertical direction is input, the camera DSP unit 103 reads a photometric condition (for example, FIG. 3A) corresponding to the case where the mobile phone 200 is in the vertical direction. . Then, the camera DSP unit 103 performs photometric processing by applying photometric conditions to the output of the photoelectric conversion unit 102 (step S102).

  The camera / display control / image processing unit 104 identifies whether or not the mobile phone 200 is tilted based on the output signal of the tilt detection unit 106, and when the mobile phone 200 is tilted, the mobile phone 200 is in the horizontal direction. It is determined that the mobile phone 200 is in the horizontal direction, and the camera posture information is generated and output to the camera DSP unit 103. When camera posture information indicating that the mobile phone 200 is in the horizontal direction is input, the camera DSP unit 103 reads a photometric condition (for example, FIG. 3B) corresponding to the case where the mobile phone 200 is in the horizontal direction. . Then, the camera DSP unit 103 performs photometric processing by applying photometric conditions to the output of the photoelectric conversion unit 102 (step S103).

  The camera DSP unit 103 generates exposure specifying information based on the result of the photometry process (step S104). When the user performs a specific operation for performing shooting such as pressing the shutter button on the operation unit 108, the operation unit 108 outputs information indicating that an operation for performing shooting has been performed to the control unit 107. The control unit 107 outputs information that instructs the camera / display control / image processing unit 104 to perform shooting.

  When information for instructing photographing is input, the camera / display control / image processing unit 104 outputs information for instructing photographing to the camera DSP unit 103. When information instructing photographing is input, the camera DSP unit 103 outputs exposure specifying information and information instructing photographing to the photoelectric conversion unit 102. The photoelectric conversion unit 102 receives the light incident from the lens unit 101 based on the exposure specifying information, and images the light incident from the lens unit 101 (step S105).

  As described above, according to this embodiment, since exposure control is performed under the photometric conditions corresponding to the posture of the mobile phone 200, that is, the posture of the camera, it is possible to perform photographing with appropriate exposure. In particular, even when shooting with the mobile phone 200 in the horizontal direction or when shooting in the vertical direction, it is possible to perform appropriate photometry without the influence of the sun, lighting, etc. Even in this posture, it is possible to perform an appropriate exposure setting.

Embodiment 2. FIG.
This embodiment is different from the first embodiment in that the user can set photometric conditions. Since the configuration of this embodiment is the same as that of the first embodiment, description thereof is omitted.

  The operation of this embodiment will be described with reference to the drawings. FIG. 6 is a flowchart for explaining the operation of this embodiment. First, the user operates the operation unit 108 to select a photometric condition (step S201). Here, the photometry conditions to be selected correspond to, for example, the photometry conditions stored in advance by the camera DSP unit 103 and corresponding to the case where the mobile phone 200 is in the vertical direction, and the case where the mobile phone 200 is in the horizontal direction. Metering conditions including the metering conditions set by the user by operating the operation unit 108 may be included.

  Then, the tilt detection unit 106 detects whether or not the mobile phone 200 is tilted, and outputs the detection result to the camera / display control / image processing unit 104 (step S202). Then, the camera / display control / image processing unit 104 generates camera posture information that specifies whether the mobile phone 200 is tilted and outputs the camera posture information to the camera DSP unit 103. The camera DSP unit 103 specifies the corresponding photometric conditions according to the camera attitude information, generates photometric condition information, and outputs the photometric condition information to the camera / display control / image processing unit 104. The camera / display control / image processing unit 104 outputs the photometric condition information to the control unit 107. The control unit 107 determines whether or not the input photometric condition information matches the photometric condition selected by the user (step S203).

  When the photometric condition information matches the photometric condition selected by the user, no alarm is generated by display or sound (step S204), and when the mobile phone 200 is not tilted, step S102 in the first embodiment is performed. When the subsequent operations are performed and the mobile phone 200 is tilted, the operations after step S103 in the first embodiment are performed.

  When the photometric condition information does not match the photometric condition selected by the user, the control unit 107 generates an alarm sound via the audio processing unit 109 and the speaker 111. In addition, the control unit 107 causes the display unit 105 via the camera / display control / image processing unit 104 to match the photometry condition selected by the user with the photometry condition determined in accordance with the tilt of the mobile phone 200. “No” is displayed (step S205).

  When the user changes the photometric condition selected by operating the operation unit 108, the process returns to step S201. When the user does not change the photometric condition selected by operating the operation unit 108, and the mobile phone 200 is not tilted, the operation after step S102 in the first embodiment is performed, and the mobile phone When 200 is inclined, the operations after step S103 in the first embodiment are performed.

  As described above, according to this embodiment, the user can select the photometric condition by himself / herself, and the photometric condition selected by the user does not match the photometric condition determined according to the inclination of the mobile phone 200. Generates an alarm sound or the like to notify the user that the photometric condition selected by the user does not match the photometric condition determined according to the inclination of the mobile phone 200.

  In the above-described embodiment, the tilt detection unit 106 uses a signal indicating that the mobile phone 200 is in the horizontal orientation or a signal indicating that the mobile phone 200 is in the vertical direction as a signal indicating the orientation of the mobile phone 200. Although a signal indicating that the mobile phone 200 is in the posture is output, the signal may be output in accordance with a greater degree of inclination of the mobile phone 200. For example, a signal indicating that the mobile phone 200 has an intermediate posture between the horizontal posture and the vertical posture may be output. In that case, the camera DSP unit 103 stores the photometric conditions corresponding to each of the signals corresponding to the degree of more inclination of the mobile phone 200. In the above embodiment, the weights for the areas to be weighted are set to the same value. However, the weights of the areas may be varied. Further, in the above-described embodiment, the case where the camera DSP unit 103 stores the photometry conditions related to multi-photometry is taken as an example. However, the camera DSP unit 103 stores the photometry conditions related to other photometry methods. Also good. For example, metering conditions (information indicating a metering area) related to spot metering are stored in the camera DSP unit 103, and when zoom shooting is performed, metering may be performed using the metering conditions related to spot metering. .

  The mobile device according to the present invention has been described as being realized as a mobile phone as an example of the embodiment. However, the present invention is not limited to this, and may be built in another device or as a mobile device or a camera alone. It may be realized.
