  The central control unit 101 controls each unit of the imaging device 1. Specifically, although not shown, the central control unit 101 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), and a ROM (Read Only Memory), and includes various processing programs for the imaging apparatus 1 (illustrated). Various control operations are performed according to (omitted).

The operation input unit 102 is for performing a predetermined operation of the imaging apparatus 1.
For example, the operation input unit 102 includes a main body side shutter button (main body side operation means) 102 a for inputting an instruction to record an image of a subject imaged by the imaging unit 104. Although not shown, the operation input unit 102 may include a selection / decision button related to an instruction to select an imaging mode, a function, etc., a zoom button (neither is shown) related to a zoom amount adjustment instruction, and the like. .
Then, the operation input unit 102 outputs a predetermined operation signal to the central control unit 101 in accordance with the operation of each button.

  The operation input unit 102 may include a touch panel (not shown) provided integrally with the display panel of the display unit 106.

The memory 103 is composed of, for example, a DRAM (Dynamic Random Access Memory) or the like, and temporarily stores data processed by each unit of the imaging apparatus 1 in addition to the central control unit 101.
Further, the memory (temporary recording means) 103 temporarily records the image data of each frame image associated with the display image data using, for example, identification information (described later) such as time information and a serial number. Specifically, the memory 103 includes a temporary recording area composed of, for example, a ring buffer, and sequentially records image data of a predetermined number of frame images in association with identification information.

  The imaging unit 104 constitutes an imaging unit that images a subject. Specifically, the imaging unit 104 includes a lens unit 104a, an electronic imaging unit 104b, and an imaging control unit 104c.

The lens unit 104a is composed of a plurality of lenses such as a zoom lens and a focus lens, for example.
The electronic imaging unit 104b is composed of, for example, an image sensor such as a charge coupled device (CCD) or a complementary metal-oxide semiconductor (CMOS), and converts an optical image that has passed through various lenses of the lens unit 104a into a two-dimensional image signal. To do.

Then, the imaging control unit 104c scans and drives the electronic imaging unit 104b with a timing generator and a driver, and an optical image formed by the lens unit 104a at a predetermined cycle is converted into a two-dimensional image signal by the electronic imaging unit 104b. The frame image is read out from the imaging area of the electronic imaging unit 104b for each screen and output to the image data processing unit 105.

In addition, the imaging control unit (adjustment unit) 104c sequentially adjusts imaging conditions when imaging an object such as AF (automatic focusing process), AE (automatic exposure process), and AWB (automatic white balance).
Specifically, the imaging control unit 104c is configured to input an image recording instruction based on a predetermined operation of the main body side shutter button 102a of the apparatus main body or the terminal side shutter button 202a of the display terminal 2 by the user, that is, The imaging conditions are sequentially adjusted when the imaging unit 104 captures a live view image. The imaging control unit 104c adjusts the imaging conditions again when the second determination unit 109b (described later) determines that no motion is detected after an image recording instruction is input.
Here, the re-adjustment of the imaging conditions after the image recording instruction is input can be performed by, for example, using the AF frame, the AE frame, the detection result of the face detection process, or the like when capturing the live view image. It is preferable that the accuracy is relatively higher than the adjustment of the imaging condition.

The image data processing unit 105 generates image data of the subject.
That is, the image data processing unit 105 sequentially processes the frame images captured by the imaging unit 104. Specifically, the image data processing unit 105 appropriately adjusts the gain for each RGB color component with respect to the analog value signal of the frame image transferred from the electronic imaging unit 104b, and then uses a sample and hold circuit (not shown). Sample and hold, convert to digital data by an A / D converter (not shown), perform color process processing including pixel interpolation processing and γ correction processing by a color process circuit (not shown), and then a digital luminance signal Y and color difference signals Cb and Cr (YUV data) are generated. Then, the image data processing unit 105 outputs the generated image data (YUV data) of each frame image to the memory 103.
In addition, the image data processing unit 105 converts each frame image to a predetermined size (for example, VGA or QVGA size) based on the display resolution of the display panel, for example, as image data for displaying each frame image constituting the live view image. ) Is reduced. Then, the image data processing unit 105 outputs the generated image data for display of each frame image to the display unit 106 or the wireless control unit 110.

  Further, the image data processing unit 105 performs processing for associating predetermined identification information with the image data of each frame image output to the memory 103 and the image data for display. For example, the image data processing unit 105 uses, as identification information, time information counted by a timing unit (not shown), a serial number counted for each imaging by the imaging unit 104, or the like to display image data or display of each frame image. It is added to the image data for use.

Is displayed.

The motion detection unit (detection means) 107 detects the motion of the apparatus main body.
Specifically, the motion detection unit 107 includes, for example, a triaxial acceleration sensor (not shown), and detects the movement of the apparatus main body based on the acceleration detected by the triaxial acceleration sensor.

The triaxial acceleration sensor detects accelerations in triaxial directions orthogonal to each other, and samples the detected signals of the respective axes at a predetermined frequency. Then, the motion detection unit 107 performs a predetermined calculation based on the detection result by the three-axis acceleration sensor to calculate the movement amount of the apparatus main body, and detects these movement amounts as the movement information of the apparatus main body. Note that the motion detection unit 107 may always detect the motion of the apparatus main body, or at a predetermined timing (for example, when an image recording instruction is input via the body-side shutter button 102a of the apparatus main body). And so on).
Then, the motion detection unit 107 outputs the detected motion information to the recording operation control unit 109.
Note that the movement of the apparatus main body includes, for example, a relatively large movement that occurs when a user who owns the apparatus main body moves or due to camera shake.

  The mode setting unit (setting unit) 108 sets a predetermined mode in which the imaging condition is adjusted by the imaging control unit 104c. For example, the mode setting unit 108 sets a predetermined mode instructed based on a predetermined operation of the operation input unit 102 by the user. Specifically, the mode setting unit 108 sets an imaging condition adjustment mode in which the imaging conditions by the imaging unit 104 are constantly adjusted.

The recording operation control unit 109 includes a first determination unit 109a, a second determination unit 109b, and an acquisition control unit 109c.
Each unit of the recording operation control unit 109 is configured by, for example, a predetermined logic circuit, but the configuration is an example and the present invention is not limited to this.

The first determination unit 109a determines whether the terminal-side shutter button 202a is operated and an image recording instruction is input, or whether the main body-side shutter button 102a is operated and an image recording instruction is input.
That is, the first determination unit (first determination unit) 109a receives a recording instruction transmitted via a predetermined wireless communication line and received via the wireless control unit 110 when the terminal shutter button 202a is operated. It is determined whether or not a recording instruction has been input via the central control unit 101 by operating the main body side shutter button 102a.

The second determination unit 109b determines whether or not the motion detection unit 107 has detected the movement of the apparatus main body.
That is, the second determination unit (second determination unit) 109b detects the movement of the apparatus main body by the movement detection unit 107 when the main body side shutter button 102a is operated and an image recording instruction is input. It is determined whether or not. Specifically, if it is determined by the first determination unit 109a that the main body shutter button 102a is operated and an image recording instruction is input, the second determination unit 109b is output from the motion detection unit 107 and input. Whether the movement of the apparatus main body is detected is determined based on the movement information.

The acquisition control unit 109c controls acquisition of an image recorded in the recording unit 111.
That is, the acquisition control unit (acquisition control unit) 109c, when it is determined by the first determination unit 109a that the terminal-side shutter button 202a is operated and an image recording instruction is input, at the time when the recording instruction is input. The image recorded in the memory 103 is acquired in association with the image displayed on the display unit 106 of the display terminal 2. Specifically, the acquisition control unit 109c receives the recording received by the wireless control unit 110 when the first determination unit 109a determines that the terminal-side shutter button 202a is operated and an image recording instruction is input. The identification information of the display image data associated with the instruction is acquired. Then, the acquisition control unit 109c refers to the memory 103 to acquire the image data of the frame image associated with the identification information of the display image data as the recording image data.

On the other hand, the acquisition control unit (acquisition control unit) 109c determines that the first determination unit 109a has operated the main body side shutter button 102a to input an image recording instruction, and the imaging control unit 104c performs imaging conditions. Is adjusted and an image captured by the imaging unit 104 is acquired. Specifically, for example, when the main body side shutter button 102a is pressed halfway, the imaging control unit 104c adjusts the imaging conditions such as AF, AE, AWB, and then the main body side shutter button 102a is fully pressed. Then, the acquisition control unit 109c acquires the image data captured by the imaging unit 104 and generated by the image data processing unit 105 as recording image data.
At this time, if the second determination unit 109b determines that the movement of the apparatus main body has been detected, the acquisition control unit 109c stores the memory 103 when the recording instruction is input by operating the main body side shutter button 102a. The image data of the newest frame image recorded in is acquired. Specifically, before the recording instruction is input by operating the shutter button 102a on the main body side, for example, when the live view image is captured, the imaging control unit 104c sequentially adjusts the imaging conditions. . Then, at the point when the recording instruction is input by operating the main body side shutter button 102 a, the acquisition control unit 109 c is the most recorded in the memory 103 without the image pickup condition being adjusted again by the image pickup control unit 104 c. Image data of a new frame image is acquired. On the other hand, when the second determination unit 109b determines that the movement of the apparatus main body has not been detected, the acquisition control unit 109c is, for example, operated by the imaging control unit 104c when the main body side shutter button 102a is half-pressed. The image data of an image captured by the imaging unit 104 with the imaging conditions adjusted is acquired as recording image data.
It should be noted that the imaging control unit 104c may adjust the imaging conditions again when the main body side shutter button 102a is fully pressed. In this case, the acquisition control unit 109c uses the imaging control unit 104c to change the imaging conditions. The image data of the image that has been adjusted again and captured by the imaging unit 104 may be acquired as image data for recording.

  In addition, when the imaging condition adjustment mode in which the imaging condition by the imaging unit 104 is constantly adjusted is set by the mode setting unit 108, the acquisition control unit 109c detects the movement of the apparatus main body by the second determination unit 109b. Even if it is determined that the image capturing condition is adjusted by the image capturing control unit 104c, the image data of the image captured by the image capturing unit 104 may be acquired. That is, when the imaging condition adjustment mode is set, for example, when the main body side shutter button 102a is half-pressed regardless of whether or not the apparatus main body moves, the imaging control unit 104c causes the AF, AE to be performed. When the image capturing condition such as AWB is adjusted and then the main body side shutter button 102 a is fully pressed, the acquisition control unit 109 c captures the image data captured by the image capturing unit 104 and generated by the image data processing unit 105. You may make it acquire as image data for recording.

The wireless control unit (communication means) 110 performs communication control of information with an external device such as the display terminal 2 connected via a predetermined wireless communication line.
That is, the wireless control unit 110 constitutes a communication unit that communicates via a predetermined communication line, and includes, for example, a wireless LAN module. Specifically, the wireless control unit 110 includes a communication antenna 110a. For example, the wireless control unit 110 directly communicates with the wireless control unit 204 of the display terminal 2 without going through an external access point (fixed base station). Operates in Peer to Peer (ad hoc mode). In this ad hoc mode, for example, various communication control information such as the communication method, encryption information, channel, and IP address of the wireless communication line are set in advance. Then, the wireless control unit 110 performs wireless communication with the wireless control unit 204 of the display terminal 2 that exists within the wireless communication range and in which common communication control information is set.

The configuration may be built in a free recording medium (not shown) or the like.

The recording unit 111 stores predetermined image data encoded in a predetermined compression format (for example, JPEG format, motion JPEG format, MPEG format, etc.) by an encoding unit (not shown) of the image data processing unit 105. Record in the recording area. Specifically, the recording unit (recording unit) 111 is an image acquired by the acquisition control unit 109c, that is, image data of a frame image associated with identification information of image data for display in the memory 103, The image data captured by the imaging unit 104 with the imaging conditions adjusted and generated by the image data processing unit 105, the image data of the newest frame image recorded in the memory 103, and the like are recorded.

The wireless control unit 204 controls communication of information with an external device such as the imaging device 1 connected via a predetermined wireless communication line.
That is, the wireless control unit 204 constitutes wireless communication means that communicates via a predetermined wireless communication line, and includes, for example, a wireless LAN module including a communication antenna 204a. Specifically, the wireless control unit 204 establishes a wireless communication line directly with the wireless control unit 110 of the imaging device 1 without going through an external access point, similarly to the wireless control unit 110 of the imaging device 1. Operates in Peer to Peer (ad hoc mode). In this ad hoc mode, similarly to the wireless control unit 110 of the imaging apparatus 1, for example, various communication control information such as the communication method, encryption information, channel, and IP address of the wireless communication line are set in advance. Then, the wireless control unit 204 performs wireless communication with the wireless control unit 110 of the imaging apparatus 1 that exists within the wireless communication range and for which common communication control information is set.

The display unit 106 sequentially displays live view images based on the input image data output from the image data processing unit 105. In addition, the wireless control unit 110 transmits the input display image data to the display terminal 2 via a wireless communication line.

The recording unit 111 records the image data of the frame image acquired by the acquisition control unit 109c (step S8), and ends the imaging process.

On the other hand, if it is determined in step S3 that the first determination unit 109a does not input an image recording instruction from the display terminal 2 (step S3; NO), the second determination unit 109b is moved by the motion detection unit 107. It is determined whether or not the movement of the apparatus main body has been detected (step S9).
If it is determined that the movement of the apparatus main body has not been detected (step S9; NO), the first determination unit 109a determines whether or not the main body side shutter button 102a has been half-pressed. (Step S10). Specifically, the first determination unit 109a determines whether or not a half-press signal output from the body-side shutter button 102a is input based on a half-press operation of the body-side shutter button 102a by the user. .

If it is determined in step S10 that the main body side shutter button 102a is not half-pressed (step S10; NO), the CPU of the central control unit 101 returns the process to step S1, and performs the subsequent processes. Control execution.
On the other hand, if it is determined that the main body side shutter button 102a is half-pressed (step S10; YES), the imaging control unit 104c again adjusts the imaging conditions when imaging an object such as AF, AE, AWB, etc. (Step S11), the first determination unit 109a determines whether or not the user has pressed the main body side shutter button 102a fully (Step S12). Specifically, the first determination unit 109a receives a full-press signal indicating an image recording instruction output from the body-side shutter button 102a based on a half-press operation of the body-side shutter button 102a by the user. It is determined whether or not.

If it is determined in step S12 that the main body side shutter button 102a has not been fully pressed (step S12; NO), the CPU of the central control unit 101 returns the process to step S10 and performs the subsequent processes. Control execution.
On the other hand, if it is determined that the main body side shutter button 102a is fully pressed (step S12; YES), the acquisition control unit 109c is imaged by the imaging unit 104 and generated by the image data processing unit 105. Are acquired as image data for recording (step S13). Thereafter, the CPU of the central control unit 101 moves the process to step S8, and the recording unit 111 records the image data of the frame image acquired by the acquisition control unit 109c (step S8), and ends the imaging process. To do.

  If it is determined in step S9 that the movement of the apparatus main body is detected (step S9; YES), the first determination unit 109a determines whether or not the main body side shutter button 102a is fully pressed by the user. Is determined (step S14). Specifically, the first determination unit 109a receives a full-press signal indicating an image recording instruction output from the body-side shutter button 102a based on a half-press operation of the body-side shutter button 102a by the user. It is determined whether or not.

If it is determined in step S14 that the main body side shutter button 102a has not been fully pressed (step S14; NO), the CPU of the central control unit 101 returns the process to step S9 and performs the subsequent processes. Control execution.
On the other hand, if it is determined that the main body side shutter button 102a is fully pressed (step S14; YES), the acquisition control unit 109c records the image data of the newest frame image recorded in the memory 103 for recording. It is acquired as image data (step S15). Thereafter, the CPU of the central control unit 101 moves the process to step S8, and the recording unit 111 records the image data of the frame image acquired by the acquisition control unit 109c (step S8), and ends the imaging process. To do.

As described above, according to the imaging system 100 of the present embodiment, the terminal-side shutter button 202a is operated and a recording instruction is input via the wireless control unit 110, or the body-side shutter button 102a is operated. When it is determined whether a recording instruction has been input, and it is determined that the recording instruction has been input by operating the terminal-side shutter button 202a, it is displayed on the display unit 206 of the display terminal 2 when the recording instruction is input. When it is determined that a recording instruction is input by operating the shutter button 102a on the main body side while acquiring an image recorded in the memory 103 in association with a live view image, the imaging condition is adjusted and the imaging unit Since the image captured by the camera 104 is acquired, the user can use the terminal-side shutter button 202a and the body-side shutter button 102a. Depending on the shutter button that is more manipulation, image acquisition can be switched, it is possible to properly capture an image intended by the user accordingly.
That is, when the user operates the shutter button 202a on the terminal side, it is considered that the user has taken a live view image displayed on the display unit 206 of the display terminal 2 and is displayed on the display unit 206. For example, an image recorded in the memory 103 in association with the live view image may be acquired using predetermined identification information so as not to cause a time delay from the time when the live view image is captured. it can. On the other hand, when the user operates the shutter button 102a on the main body side, for example, the user wants to capture an image in which various imaging conditions such as AF, AE, and AWB are adjusted in consideration of the composition, the angle of view, and the like. Therefore, it is possible to acquire an image in which the imaging conditions are appropriately adjusted according to the subject.
As a result, an appropriate image can be automatically acquired and recorded in consideration of the user's intention of imaging.

Further, when a recording instruction is input by operating the main body side shutter button 102a, it is determined whether or not the movement of the imaging apparatus 1 is detected, and it is determined that the movement of the main apparatus body is detected. When the main body side shutter button 102a is operated and a recording instruction is input, the latest image recorded in the memory 103 is acquired, while it is determined that the movement of the apparatus main body is not detected. Since the image captured by the image capturing unit 104 is acquired by adjusting the image capturing condition, the image intended by the user is appropriately captured in consideration of the movement of the image capturing apparatus 1 when the main body side shutter button 102a is operated. can do. That is, when the movement of the imaging device 1 is detected, for example, it is considered that the user has operated the main body side shutter button 102a while moving, and therefore the memory 103 is not adjusted without adjusting the imaging conditions. The newest recorded image can be acquired. On the other hand, when the movement of the imaging device 1 is not detected, the user may want to capture an image adjusted for various imaging conditions such as AF, AE, and AWB, as described above. Accordingly, it is possible to acquire an image in which the imaging conditions are appropriately adjusted.
At this time, the imaging unit 104 sequentially adjusts the imaging conditions before the main body side shutter button 102a is operated and the recording instruction is input, and after determining that the movement of the imaging device 1 is not detected, the imaging unit Since the image pickup condition by 104 is adjusted again, the image pickup condition may be adjusted to some extent even for the newest image recorded in the memory 103 acquired when the movement of the image pickup apparatus 1 is detected. On the other hand, an image acquired when the movement of the imaging device 1 is not detected can be captured by appropriately adjusting the imaging conditions according to the subject.

  In addition, when the imaging condition adjustment mode in which the imaging condition by the imaging unit 104 is constantly adjusted is set by the mode setting unit 108, the imaging condition is adjusted even if it is determined that the movement of the imaging device 1 is detected. Since the image captured by the image capturing unit 104 is acquired, for example, when there is camera shake or when the user intentionally performs the panning, the image is not adjusted and the image capturing condition is not adjusted. Can be prevented from being imaged.

The present invention is not limited to the above-described embodiment, and various improvements and design changes may be made without departing from the spirit of the present invention.
For example, in the above embodiment, the imaging apparatus 1 records an image acquired under the control of the acquisition control unit 109c. However, the image capturing apparatus 1 is an example and is not limited thereto. Whether or not to record can be arbitrarily changed as appropriate. That is, the imaging apparatus 1 does not necessarily include the recording unit 111 and may be configured to transmit and record the acquired image to an external device via a predetermined communication line.

  In the above embodiment, for example, a wireless communication line has been described as an example of the predetermined communication line. However, the predetermined communication line is a wired communication line that performs communication by connecting the imaging device 1 and the display terminal 2 with a wired cable or the like. May be. That is, since the amount of noise is considered to change depending on various conditions (for example, length, thickness, material, etc.) of the wired cable connecting the imaging device 1 and the display terminal 2, the communication quality is affected, and the live view The display of the image is delayed in time from the time when the image is captured.

  Further, for example, when image capturing is automatically performed at a predetermined timing in interval shooting or the like, the memory 103 is adjusted without adjusting the image capturing conditions in substantially the same manner as when the movement of the image capturing apparatus 1 is detected. The latest image recorded in the image may be acquired.

  In addition, the configuration of the imaging system 100 and the configuration of the imaging device 1 and the display terminal 2 included in the imaging system 100 are merely examples illustrated in the above-described embodiment, and are not limited thereto.

In addition, in the above embodiment, the functions of the first determination unit and the acquisition control unit are controlled by the first determination unit 109a and the acquisition control unit 109c under the control of the central control unit 101 of the imaging apparatus 1. Although the configuration is realized by driving, the configuration is not limited to this, and the configuration may be realized by executing a predetermined program or the like by the central control unit 101.
That is, a program including a first determination processing routine and an acquisition control processing routine is recorded in a program memory (not shown). Then, in the first determination processing routine, the CPU of the central control unit 101 is operated to operate the terminal side operation means and input a recording instruction via the communication means, or the main body side operation means is operated to issue a recording instruction. You may make it function as a means to determine whether it was input. Further, when it is determined by the acquisition control processing routine that the CPU of the central control unit 101 is operated by operating the terminal side operation means and the recording instruction is input, the CPU is displayed on the display means when the recording instruction is input. While it is determined that the recording instruction is input by operating the main body side operation unit while acquiring the image recorded in the temporary recording unit in association with the image, the imaging condition is adjusted and the image is captured by the imaging unit. It may be made to function as a means for acquiring the acquired image.

  Similarly, the detection unit, the second determination unit, the adjustment unit, the setting unit, and the recording unit may be realized by executing a predetermined program or the like by the CPU of the central control unit 101 of the imaging apparatus 1. good.

  Furthermore, as a computer-readable medium storing a program for executing each of the above processes, a non-volatile memory such as a flash memory or a portable recording medium such as a CD-ROM is applied in addition to a ROM or a hard disk. Is also possible. A carrier wave is also used as a medium for providing program data via a predetermined communication line.
