Furthermore, the video camera 100 includes an operation unit 114, a digital I / F 115, an input / output unit 116, and a power supply control unit 117. Note that the zoom knob 114a, the still image capturing button 114b, the power button 114c, the mode dial 114d, and the moving image capturing button 114e illustrated in FIG. 2 are collectively expressed as the operation unit 114.

  The functional blocks are connected to each other via a data bus 118 so that data communication is possible.

  In such a video camera 100, the memory 111 has a program storage area and a data work area, is used by time sharing in each functional block via the data bus 118, and is controlled and managed by the memory control unit 112. Has been.

  The operation unit 114 has a function of instructing the CPU 113 to perform an operation based on an operation from the photographer with respect to the keys and buttons shown in FIG.

  The power control unit 117 includes a battery detection circuit, a DC-DC converter, a switch circuit that changes a block to be energized, and the like, and detects whether or not a battery is installed, the type of battery, and the remaining battery level.

  Basic operations such as an imaging operation, a recording operation, and a reproduction operation of the video camera 100 having the above configuration will be described.

  For example, when an imaging operation and a recording operation are instructed by the operation unit 114, light from the subject becomes an optical signal whose predetermined brightness, angle of view, focus, and the like are controlled by the lens 101 to the imaging unit 102. Input.

  The imaging unit 102 converts the input optical signal into an electrical signal and outputs the electrical signal to the camera signal processing unit 103. The camera signal processing unit 103 converts this electric signal into a digital image signal. The image signal is subjected to signal processing such as color separation, gradation correction, and white balance adjustment, and then output.

  On the other hand, the audio signal processing unit 110 outputs the audio signal as audio data by gain-controlling the audio signal input from the microphone 109 to a predetermined level and digitizing it.

  The compression / decompression processing unit 104 compresses and encodes the image data output from the camera signal processing unit 103 and the audio data output from the audio signal processing unit 110 using a predetermined compression encoding method.

  The recording / playback processing unit 106 performs error correction coding processing, modulation processing, and the like on the data after compression coding obtained by the compression / decompression processing unit 104. Further, the recording / playback processing unit 106 adds data such as synchronization and ID and converts it into a form suitable for recording, and then records it on a recording medium such as a memory card 119. At this time, the card control unit 107 also performs recording control of the memory card 119.

  On the other hand, when a reproduction operation is instructed by the operation unit 114, the recording / reproduction processing unit 106 detects original digital data from data read from the memory card 119, and performs processing such as error correction and demodulation. Further, the recording / reproducing processor 106 generates a clock synchronized with the reproduced data by a PLL circuit.

  The compression / decompression processing unit 104 performs decompression processing corresponding to a predetermined compression encoding method on the data output from the recording / playback processing unit 106, and acquires imaging data and audio data before compression encoding. The display unit 105 displays the reproduction data obtained by the compression / decompression processing unit 104.

  When the operation unit 114 instructs to record input data from the digital I / F 115, the CPU 113 inputs the image data or audio data from the external device 121 in the form of a digital signal by the digital I / F 115 and records it. The data is sent to the reproduction processing unit 106.

  At this time, it is assumed that image data and audio data from the external device 121 have already been encoded, and the recording / playback processing unit 106 performs processing necessary for recording on the input data as described above to perform the memory card 119. Record it on a recording medium.

  When the operation unit 114 instructs to record an input signal from the input / output unit 116, the CPU 113 controls the input / output unit 116 and inputs an image and audio signal output from the external device 122.

  The input / output unit 116 converts the image and audio signals output from the external device 122 into digital data and outputs the digital data to the memory 111. The CPU 113 outputs the image and audio data stored in the memory 111 to the compression / decompression processing unit 104, compression-codes them, and sends them to the recording / reproduction processing unit 106.

  As described above, the recording / playback processing unit 106 performs processing necessary for recording on the compression-encoded data and records the data on a recording medium such as the memory card 119.

  The face detection processing unit 108 applies horizontal and vertical bandpass filters to the image data to be detected from the camera signal processing unit 103. Edge components are detected from the image data by these horizontal and vertical band-pass filters.

  After that, the face detection processing unit 108 performs pattern matching on the detected edge component, and extracts a candidate group of eyes, nose, mouth, and ears. Then, the face detection processing unit 108 determines that an eye pair satisfying a preset condition (for example, distance between two eyes, inclination, etc.) from the extracted eye candidate group is an eye pair. Narrow down the candidate group of only those with.

  Further, the face detection processing unit 108 associates the narrowed-down eye candidate group with other parts (nose, mouth, ears) that form the corresponding face, and passes a preset non-face condition filter. Then, a face that is a specific object is detected.

  The face detection processing unit 108 outputs face information (for example, face number information, eye and nose, mouth, and ear position information) according to the face detection result, and ends the process. At this time, the face information is stored in the memory 111. As described above, the face detection processing unit 108 corresponds to a detection unit that detects a specific object from the captured image.

  FIG. 4 is a flowchart showing the procedure of the imaging process in the first embodiment executed by the CPU 113 in FIG.

  The imaging process shown in FIG. 4 includes a face selection and confirmation process procedure in the moving image imaging mode. This imaging process is started when the photographer turns on the power by pressing the power button 114c and sets the mode dial 114d to the moving image imaging mode. Here, the face selection and determination processing in the moving image capturing mode will be described as the same example regardless of whether the image capturing is in progress or in the standby state.

  In FIG. 4, when the moving image capturing mode process is started, a real-time through image of the captured moving image is displayed on the display unit 105 (step S101). Next, the face detection processing unit 108 performs the above-described face detection processing (step S102).

  An initial face selection process is performed from the face detected in step S102 (step S103). In this initial face selection process, the face to be selected first from the faces detected by the face detection processing unit 108 is determined as the main face. In this process, a detection frame, which will be described later, is superimposed on the determined main face and displayed on the display unit 105. The method for determining the face to be selected first may be, for example, the face located on the leftmost side of the screen or the face closest to the center of the screen. Also, the largest face may be used.

  FIG. 5 is a diagram showing a screen showing the initial face displayed on the display unit 105 in FIG.

  FIG. 5 shows that the selection screen 501 indicating the main face is superimposed and displayed on the initial face by the initial face selection process. Note that when the initial face is selected as the main face, an imaging process optimized for the initial face such as the face AF, the face AE, and the face AWB may be performed.

  Here, the face AF performs focus adjustment on the detected face. The face AE is exposure adjustment that optimizes the exposure of the entire captured image in accordance with the detected brightness of the face. The face AWB is white balance adjustment that adjusts the white balance in accordance with the detected face.

  As described above, the initial face selection process includes a superimposing unit that superimposes the selection frame 501 (selected image) indicating that one face is selected from the detected faces on the face and displays the selected frame 501 on the display unit 105. Corresponding to

  Next, it is determined whether or not the still image capturing button 114b is half-pressed (step S104). If the result of determination in step S104 is that the still image capture button 114b has been pressed halfway, face selection change processing is performed (step S105). This face selection changing process corresponds to changing means for changing the face on which the selection frame 501 is superimposed when the still image capturing button 114b is pressed halfway, and details will be described later. In step S104, it is determined whether or not half-pressed until half-pressed.

  Next, it is determined whether or not the still image capturing button 114b has been fully pressed (step S106). If the result of determination in step S106 is that the still image capture button 114b has not been fully pressed, processing returns to step S104. On the other hand, when it is determined that the still image capture button 114b is fully pressed, the currently selected face is determined, and face AF (focus processing), face AE (exposure adjustment processing), face AWB (white balance adjustment processing), etc. The imaging process optimized for is performed (step S107). At this time, the configuration and color of the selection frame 501 may be changed in order to inform the photographer that the selected face has been confirmed. When the process of step S107 ends, the process returns to step S104. As described above, in step S107, when the still image capturing button 114b is fully pressed, the image capturing unit 102 is controlled so that the face on which the selection frame 501 is superimposed is captured as the main subject. Note that the imaging unit 102 may be controlled so as to capture the face as the main subject by performing at least one of the face AF, the face AE, and the face AWB for the main subject.

  The face selection change process will be described. For example, if there is a face recognized in the right direction from the currently selected face, the right face is changed as the main face.

  6, 7, and 8 are diagrams illustrating a screen showing the main face displayed on the display unit 105 after the change by the selection change process.

  FIG. 6 shows that a selection frame 501 is displayed on the right face of the face selected in FIG.

  Note that, as shown in FIG. 7, there may be no face recognized to the right of the face with the main face. At that time, as shown in FIG. 8, the face located farthest in the opposite direction is selected as the main face. In FIG. 8, the main face is changed to the leftmost face located in the opposite direction.

  As described above, in the present embodiment, the right direction has been described as the specific direction for changing the main face. However, the change method is not limited to this, and for example, the direction may be changed to the left direction in order or the vertical direction. good. Or you may change and change at random.

  According to the process of FIG. 4, when the still image capturing button 114b is half-pressed, the object on which the selection frame 501 is superimposed is changed. When the still image capturing button 114b is fully pressed, the image capturing unit 102 is controlled so that the face on which the selection frame 501 is superimposed is captured as the main subject. As a result, it is possible to provide the video camera 100 in which the operation of the photographer is simplified without providing a new operation member dedicated to the change operation and the confirmation operation of the object.

  Further, in this embodiment, half-press and full-press operations that are not used in the normal moving image capturing mode can be used as a single operation member for the face changing operation and confirming operation when the photographer selects a desired face. Use a still image capture button that is a two-stage switch. As a result, since it is not necessary to newly provide a dedicated operation member, it is possible to prevent the video camera 100 from becoming large.

  Furthermore, since the still image capturing button is normally disposed at a place where it is easy to operate in a gripped state, it is easy to operate and it is possible to prevent the video camera from blurring during a face changing operation and a finalizing operation.

  In addition, the photographer performs the face changing operation by half-pressing the still image pickup button, and performing the confirming operation by full-pressing operation, such as face AF, face AE, face AWB, etc. The configuration is such that optimized imaging processing is performed. Therefore, since the imaging process of the face AF, the face AE, the face AWB, and the like is not performed in the selection process, it is possible to prevent the captured moving image from becoming unsightly.

[Second Embodiment]
The configuration of the video camera in the second embodiment is the same as that of the video camera 100 in the first embodiment shown in FIGS.

  In the first embodiment, a still image capturing button is used for a face changing operation and a determining operation when the photographer selects a desired face. In contrast, in the second embodiment, a processing operation in the case of capturing a still image during moving image capturing will be described.

  FIG. 9 is a flowchart showing the procedure of the imaging process in the second embodiment executed by the CPU 113 in FIG.

  The imaging process shown in FIG. 9 includes a face selection and confirmation process procedure in the moving image imaging mode. Further, in the second embodiment, it is possible to perform a face change operation and a determination operation and a still image capturing operation when the photographer selects a desired face with the still image capturing button 114b. This imaging process is started when the photographer turns on the power by pressing the power button 114c and sets the mode dial 114d to the moving image imaging mode. Here, the face selection / confirmation process and the still image capturing process in the moving image capturing mode will be described as the same example regardless of whether the image capturing is in progress or in the standby state, so description of whether the capturing is in progress or the standby state is omitted. .

  Steps S201 to S204 are the same processing as S101 to S104 of FIG. 4 described in the first embodiment, and thus description thereof is omitted.

  As a result of the determination in step S204, when the still image capturing button 114b is half-pressed (YES in step S204), time counting after the still image capturing button 114b is half-pressed is started (step S205).

  Next, it is determined whether or not the count time T1 that has elapsed since the time count is started is greater than a predetermined time T (step S206). As a result of the determination in step S206, when the count time T1 is greater than the predetermined time T (YES in step S206), the face selection change process in step S105 described above is performed (step S209).

  Next, it is determined whether or not the still image capturing button 114b has been fully pressed (step S210). As a result of the determination in step S210, when the still image capturing button 114b is not fully pressed (NO in step S210), the process returns to step S204.

  On the other hand, when the still image capture button 114b is fully pressed (YES in step S210), the currently selected face is determined in the same manner as in step S104 described above, and the face AF, face AE, face AWB, etc. are optimized. An imaging process is performed (step S211), and the process returns to step S204.

  On the other hand, as a result of the determination in step S206, when the count time T1 is equal to or shorter than the predetermined time T (NO in step S206), it is further determined whether or not the still image capturing button 114b is fully pressed (step S207). ).

  As a result of the determination in step S207, when the still image capturing button 114b is fully pressed (YES in step S207), the currently selected face is determined and optimized still images such as face AF, face AE, face AWB, etc. Imaging is performed (step S208), and the process returns to step S204.

  On the other hand, when the still image capturing button 114b is not fully pressed (NO in step S207), the process returns to step S206.

  As described above, in the second embodiment, the time from when the still image capturing button is pressed halfway down until it is fully pressed is counted. The image is captured.

  Therefore, the photographer can capture a still image during moving image capturing by operating the still image capturing button from half-press to full-press at once. In addition, the photographer can perform the face change operation by half-pressing the still image capture button, and the operation that takes a certain amount of time from half-press operation to full-press operation, such as confirming operation by full-press operation, can be used properly .

  As a result, a face changing operation and a confirming operation with still image capturing during moving image capturing can be performed with a still image capturing button of a single operation member. Furthermore, since it is not necessary to newly provide a dedicated operation member, it is possible to prevent the imaging apparatus main body from being enlarged.

  According to the processing of FIG. 9, the selection frame is displayed when the half-pressing operation is performed when the time T1 elapsed from the half-pressing operation of the still image capturing button 114b to the full-pressing operation being equal to or less than a predetermined time T. The imaging unit 102 is controlled so as to capture the face with the superimposed 501 as the main subject. As a result, it is possible to provide the video camera 100 in which the operation of the photographer is simplified without providing a new operation member dedicated to the change operation and the confirmation operation of the object.
