Description

  The present invention relates to an imaging apparatus and an imaging apparatus control method, and more particularly to a technique suitable for use in wireless transmission control for automatically transmitting an image recorded by an imaging apparatus to an external device.

  2. Description of the Related Art In recent years, imaging devices capable of transmitting images with a wireless communication function are known. The wireless transmission function may detect whether or not wireless communication with an external device is possible, and automatically start image transmission from the imaging device when it is determined that wireless communication is possible.

  In such an imaging apparatus, the wireless transmission operation is executed at random during activation in an imaging mode (moving image or still image) included in the imaging apparatus, that is, during subject shooting. For this reason, the image pickup unit of the image pickup apparatus is affected by the influence of radio waves generated during the wireless transmission operation or the fluctuation of the GND potential due to the current fluctuation generated at the time of transmission. As a result, the captured image has interference noise. Occurs and the image quality is degraded.

In order to avoid this, a technique has been proposed in which interference noise is prevented from occurring in a captured image by stopping the imaging operation during the wireless transmission operation (see, for example, Patent Document 1).
In addition, a technique for controlling the wireless transmission operation according to a mode change function (for example, recording standby state / recording state / imaging mode / reproduction mode) included in the imaging apparatus to prevent interference noise from being generated in the captured image. Is also known.

JP 2004-088447 A

Even during shooting, there are cases where there is a high and low possibility that interference noise will occur in the shot image. However, in the example of Patent Document 1, imaging is not always possible during wireless transmission operation, or wireless transmission is not always possible during imaging, regardless of whether interference noise is likely to occur in the captured image. There was a possibility of restricting shooting or wireless transmission more than necessary.
In view of the above-described problems, the present invention appropriately controls the timing of automatically transmitting a recorded image to an external storage device according to the shooting state of the imaging device, and causes interference noise in the recorded image.

  According to the present invention, since it is determined whether or not the shooting state of the imaging device is likely to be subjected to noise and the wireless transmission is restricted at an appropriate timing, the possibility that interference noise occurs in the shot image is reduced. It becomes possible to make it.

In addition, a wireless reception unit 16 is provided for receiving a signal indicating whether or not the imaging apparatus is capable of wireless transmission with an external device. Note that the wireless unit may be internal or external.

  With the configuration as described above, the image data in the internal recording memory 13 or the external recording memory inserted in the external memory slot 14 is wirelessly transmitted to the external device during the imaging mode of the imaging apparatus of the present embodiment. It is determined whether or not this is possible. If transmission is possible, it is determined whether to perform wireless transmission according to a result of comparing a camera control gain value, which is an exposure correction control value included in the imaging apparatus, with a reference gain value provided in advance. . Then, by performing transmission control according to the determination result, it is possible to eliminate the influence on the image being wirelessly transmitted and to prevent the image quality from being deteriorated.

<First Embodiment>
Hereinafter, the operation of the imaging apparatus of the present embodiment will be specifically described.
In FIG. 1, the optical signal that has passed through the lens 1 is input to the solid-state imaging device 3 through the diaphragm 2. The solid-state imaging device 3 is driven by a driving pulse output from the TG 6, converts an incident optical signal into an electrical signal by photoelectric conversion, and then outputs the electrical signal.

  The electrical signal output from the solid-state imaging device 3 is input to the AGC 5 through the CDS A / D 4 that converts the analog signal into a digital signal after performing correlated double sampling. The AGC 5 outputs a desired signal to the camera signal processing circuit 7 by multiplying the input signal by a gain according to the brightness at the time of shooting the subject.

  The camera signal processing circuit 7 performs Y / C separation, video signal processing, color signal processing, and gamma correction on the input signal to generate an image. In addition, a luminance value is calculated from the input signal for calculating an exposure evaluation value for performing exposure correction according to the brightness of the subject.

  The image generated by the camera signal processing circuit 7 is input to the video signal processing circuit 10. The video signal processing circuit 10 performs optimal processing on the video signal, and then outputs a video signal to the LCD 12 serving as a display device. Further, when recording is started by the recording selection means provided in the imaging apparatus, or when a release button for still image recording is selected, the video signal input by the video signal processing circuit 10 and the memory 11 is The encoding / decoding process is performed. Then, the image is output to the internal recording memory 13 designated in advance by the user or the external recording memory inserted in the external memory slot 14 to record the image.

  Next, a description will be given of an operation for automatically wirelessly transmitting image data to / from an external device when image data is recorded in the internal recording memory 13 or an external recording memory inserted in the external memory slot 14. To do.

  In order to wirelessly communicate with an external device and an external device inside or outside the imaging apparatus, the CPU 9 outputs a transmission command to the wireless transmission control unit 15 and simultaneously switches the switch 17 to the transmission mode. The wireless transmission control unit 15 transmits a radio wave to the receiving antenna of the external device via the switch 17 and the antenna 18 in response to a command input from the CPU 9 via the switch 17 and the antenna 18. Thereafter, the CPU 9 transmits a switch switching signal to the switch 17 so that the signal flows to the wireless reception unit 16 side.

  When the external device detects the received radio wave signal and determines “communication OK”, the external device transmits a synchronization signal indicating communication OK to the imaging device. The imaging apparatus receives the synchronization signal indicating “communication OK” transmitted from the external device by the antenna 18, and outputs a radio signal to the wireless reception unit 16 via the switch 17.

  The wireless receiver 16 converts the input radio signal into a baseband signal, and then outputs a synchronization signal to the CPU 9. The CPU 9 compares the synchronization signal input from the wireless reception unit 16 with the synchronization signal transmitted for confirmation of connection with the external device, and determines that “communication is OK” if they match. When it is determined that “communication is OK” with the external device, the video signal processing circuit 10 outputs a signal indicating “transmission OK” to the external device.

  The video signal processing circuit 10 takes out the image data from the internal recording memory 13 in which the image data is recorded or the external recording memory inserted into the external memory slot 14 in accordance with the signal input from the CPU 9 and wirelessly transmits it. Image data is output to the control unit 15. Here, the CPU 9 outputs a signal indicating “transmission OK” to the video signal processing circuit 10 and simultaneously switches the switch 17 to the wireless transmission control unit 15 side in order to execute radio wave transmission.

  The wireless transmission control unit 15 modulates the input image data into a desired wireless system, and then converts it to a transmission frequency. Thereafter, the image data is wirelessly transmitted from the antenna 18 to the external device via the switch 17.

  After performing wireless transmission and transmitting the image data recorded in the recording memory of the imaging apparatus to the external device, the CPU 9 notifies the video signal processing circuit 10 whether or not all the image data recorded in the recording memory of the imaging apparatus has been transmitted. Check. When all the transmissions are determined to be complete, the CPU 9 transmits a transmission stop signal to the wireless transmission control unit 15 and stops the wireless transmission function of the image data.

Next, a method of wireless transmission control of image data will be described with reference to FIG. 2 using camera control gain values provided in the imaging apparatus.
In the CPU 9, the comparator 100 compares the output signal from the exposure evaluation value calculation unit 8 with the exposure determination reference value 101 provided in advance in the CPU 9.

  The comparator 100 determines whether or not the exposure state of the subject currently being photographed is appropriate exposure, and outputs a signal to the exposure control unit 102 if it is determined that it is outside the appropriate exposure range. The exposure control unit 102 calculates a control signal for optimal exposure from the aperture control 103, the electronic shutter control 104, and the AGC control 105 provided therein, and controls the aperture 2, TG6, and AGC5. Is output.

  Here, when the AGC control 105 is in an operating state, particularly when the subject photographing is in a low illumination state, the control value of the AGC control 105 is output to the transmission determination unit 106. The signal input to the transmission determination unit 106 is input to the comparator 108 provided inside the transmission determination unit 106.

  The comparator 108 is supplied with a reference gain control value 107 prepared in advance for determining whether or not to transmit image data wirelessly. The comparator 108 determines whether or not to perform wireless transmission from the two input signals, and outputs image data transmission information to the video signal processing circuit 10 when it is determined that wireless transmission is to be performed.

  Further, after determining that wireless transmission is to be performed, a control signal is output so that the switch 17 is switched from the transmission / reception switch control unit 109 provided in the CPU 9 to the wireless transmission control unit 15 side. Note that the device (wireless unit) that performs wireless communication may be a separate device from the imaging device as described above. In this case, the imaging device only needs to have an interface with the wireless communication device and means for controlling the function of the wireless communication device using a command or the like.

Further, a memory card with a so-called communication function in which a wireless communication device and an external memory are integrally formed may be used. In this case, when a memory card with a communication function is inserted into the external memory slot 14, the imaging apparatus accesses the memory card with a communication function and controls the communication function using a command or the like.
Further, each configuration illustrated in FIG. 2 may be provided as individual hardware. Further, the hardware may include only the CPU 9, and the CPU 9 may behave as hardware that functions as each component illustrated in FIG. 2 by reading various programs.

  Next, the operation of the comparator 108 when wirelessly transmitting the image data recorded inside the imaging apparatus will be described with reference to FIG. While the AGC control 105 provided in the imaging apparatus is in operation, the AGC control value increases as the brightness during subject photographing decreases. The maximum value at which the AGC control value can be operated is defined as the MAX gain.

  The reference gain control value described in FIG. 3 is set as the reference gain control value A up to the MAX gain. Therefore, when the AGC control value is equal to or less than the reference gain control value A, the wireless transmission control is in the “ON” state, and when the AGC control value is equal to or greater than the reference gain control value A, the wireless transmission control is in the “OFF” state. It becomes. Of course, the reference gain control value A may be set to the value of the MAX gain.

Next, the operation of image wireless transmission control to an external device according to the camera control gain value, which is an exposure correction parameter provided in the imaging apparatus, will be described using the flowchart of FIG. The following flowchart is realized by the CPU 9 controlling each part of the imaging apparatus according to an input signal or a program.
In S400, the imaging apparatus is turned on. In step S401, a recording standby state in the subject shooting mode is set. In step S <b> 402, it is determined whether image data exists in an internal recording memory provided in the imaging apparatus or an external recording memory inserted in the external memory slot 14.

  Next, the process proceeds to S403, and if it is determined in the determination result that there is no image data in the recording memory, the process proceeds to S411 and control is performed so as not to perform the wireless transmission operation to the external device. On the other hand, if it is determined that there is image data in the recording memory as a result of the determination, the process proceeds to S404, where it is determined whether to perform wireless communication with the external device.

  Next, the process proceeds to S405, and if it is determined in the determination result that wireless communication with the external device is not possible, the process proceeds to S411 and the wireless transmission operation to the external device is not performed. On the other hand, if it is determined in the determination result that the wireless communication with the external device is possible, the process proceeds to S406 to detect the current exposure state during photographing of the subject, particularly the camera control gain value.

  In step S407, it is determined whether the detected camera control gain value is larger than a reference gain control value provided in advance in the imaging apparatus. If the detected camera control gain value is larger than the reference gain control value in this determination result, it is determined that the wireless transmission is inappropriate, and the process proceeds to S412 to control not to perform the wireless transmission operation. Here, even when the wireless transmission operation is not performed, the camera control gain value detection during photographing of the subject is performed again, and if it is below the reference gain control value for a certain period, control is performed to shift to the wireless transmission operation. .

  On the other hand, if it is determined in the determination result that the detected camera control gain value is smaller than the reference gain control value, it is determined that wireless transmission is appropriate, and control is performed to start the wireless transmission operation in S408. The image data inside the imaging apparatus is transmitted to the external device. During the wireless transmission of image data to an external device, the camera control gain value at the time of subject shooting is always detected. If the camera control gain value is smaller than the reference gain control value, the wireless transmission is continued. Control to do. Further, when the value is larger than the reference gain control value, control is performed so as to stop the wireless transmission.

  In step S409, it is determined whether image data that has not been wirelessly transmitted remains in the recording memory included in the imaging apparatus after the image data is wirelessly transmitted to the external device. If it is determined that image data still remains, the process returns to S408 to continue the wireless transmission to the external device. On the other hand, if all the image data has been transmitted, the process proceeds to S410 to control to stop wireless transmission to the outside.

  As described above, in the present embodiment, in order to control whether or not to wirelessly transmit image data recorded in the imaging apparatus during subject photographing, the current exposure state during subject photographing, particularly the camera control gain, is controlled. The value is detected and compared with a reference gain control value prepared in advance.

  If the current camera control gain value is smaller than the reference gain control value as a result of the comparison, control is performed to start a wireless transmission operation to an external device. On the other hand, when the control gain value is larger than the reference gain control value, control is performed so as not to perform the wireless transmission operation to the external device. Further, even during the wireless transmission operation to the external device, the camera control gain value during subject shooting is detected, and the detection result is compared with the reference gain control value, which is larger than the reference gain control value. In the event of a failure, the wireless transmission is controlled to stop.

  Thus, by performing wireless transmission ON / OFF control according to the control gain value at the time of subject shooting, even in the subject shooting mode, wireless transmission is not performed in a low illumination environment where interference noise is easily noticeable in the image. Control. As a result, the interference noise hardly affects the image, and as a result, it is possible to prevent the image quality from deteriorating.

<Second Embodiment>
In the first embodiment, the method of performing the wireless transmission ON / OFF control to the external device according to the camera control gain value at the time of shooting the subject has been described.
On the other hand, in the second embodiment, the reference gain value for wireless transmission determination described in the first embodiment is switched according to the storage time of the solid-state imaging device (hereinafter referred to as an electronic shutter). A method of performing wireless transmission ON / OFF control based on the reference gain control value will be described with reference to the flowchart of FIG.

If it is determined in S405 (wireless communication OK?) In the flowchart shown in FIG. 4 that the wireless communication with the external device is “OK”, the processing shown in the flowchart in FIG. 5 is started.
First, in S501, the current speed of the electronic shutter at the time of subject shooting is detected. Next, in S502, the result of speed detection is compared with a reference shutter speed value provided inside the imaging apparatus.

  If the comparison result shows that the current electronic shutter speed, that is, the electronic shutter speed at the time of subject shooting, is faster than the reference shutter speed, the process proceeds to S503, and the reference gain control value A is read. On the other hand, if the current electronic shutter speed is slower than the reference shutter speed, the process proceeds to S504, and the reference gain control value B is read.

  Next, in S505, the current camera control gain value at the time of subject shooting is detected, and the detection result is compared with the reference gain control value (S506). As a result of this comparison, if the reference gain control value or less is determined, it is determined that wireless transmission is possible. In this case, the process proceeds to S507, and control is performed to start the wireless transmission operation. Then, the image data inside the imaging apparatus is transmitted to the external device, and the wireless transmission is controlled until the transmission of all the image data in the recording memory included in the imaging apparatus is completed (S508 to S510).

  Here, detection / comparison of the current electronic shutter speed is continued even during the image data wireless transmission operation. When the condition for changing the reference gain control value is satisfied, the reference gain control value is changed. Then, the detection of the camera control gain value and the comparison with the changed reference gain value are continued, and the wireless transmission to the external device is stopped when the wireless transmission condition is not satisfied according to this result. Control. Furthermore, even after wireless transmission is stopped, electronic shutter speed detection / comparison and camera control gain value detection / comparison are performed, and control is performed so that wireless transmission to an external device is restored when the conditions are satisfied.

  The above operation will be specifically described. For example, in an imaging apparatus capable of controlling the camera control gain value, which is an exposure correction control value, from 0 dB to 30 dB, the reference gain value A is “20 dB” when it is faster than the reference shutter speed, and the reference control when it is slower than the reference shutter speed. The gain value B is “10 dB”. In this imaging apparatus, when the reference shutter speed is 1/60 s and the current electronic shutter speed at the time of subject shooting is 1/100 s, “20 dB” that is the reference gain control value A is read. .

  On the other hand, if the current electronic shutter speed at the time of subject shooting is 1/30 s, the reference gain control value B “10 dB” is read out. Therefore, when the electronic shutter speed at the time of subject shooting is 1/100 s, the reference gain control value is “20 dB”. For this reason, when the current camera control gain value is “20 dB” or less, control is performed to execute wireless transmission to the external device. When the current camera control gain value is “20 dB” or more, wireless transmission to the external device is performed. Control to stop transmission.

  Further, when the electronic shutter speed at the time of shooting the subject is 1/30 s, the current camera control gain value is “10 dB”. For this reason, when the current camera control gain value is “10 dB” or less, control is performed to execute wireless transmission to the external device. When the current camera control gain value is “10 dB” or more, wireless transmission to the external device is performed. Control to stop transmission.

  As described above, the reference gain control value for wirelessly transmitting the image data recorded in the imaging device is changed according to the electronic shutter speed of the solid-state imaging device currently shooting the subject during subject shooting. Then, by comparing the reference gain control value and the camera control gain value at the time of subject shooting, and performing wireless transmission control to an external device according to the comparison result, interference noise is conspicuous in the image even in the subject shooting mode. Control is performed so as not to execute wireless transmission in a low-light environment where it becomes easy. For this reason, it is possible to prevent the interference noise from affecting the image, and as a result, to reduce the quality of the image.

<Third Embodiment>
In the second embodiment, the reference gain value for performing wireless transmission ON / OFF control to an external device is changed according to the electronic shutter speed at the time of subject shooting, the changed reference gain control value, and the current camera Compare control gain values. And the method of performing wireless transmission ON / OFF control according to the comparison result was demonstrated.
In the third embodiment, a method for performing transmission power control during wireless transmission by comparing the camera control gain value during subject photographing described in the first embodiment with a reference gain control value will be described with reference to FIG. I will explain.

In the imaging apparatus, a reference gain control value A (first reference gain value) and a reference gain control value B (second) are used to control transmission power in a stepwise manner when wireless transmission to an external device is performed. ) And a reference gain control value C (third reference gain value).
Here, the relationship between the reference gain control values A, B, and C is as follows. Further, the relationship between the radio transmission power X, Y, and Z is as follows.
The relationship between the camera control gain value = 0 to n (dB) and the reference gain control values A, B, and C included in the imaging apparatus is 0 (dB)> A (dB)> B (dB)> C (dB)> n (DB) = MAX, and the wireless transmission power is normal power X (W)> Y (W)> minimum power Z (W).

  After determining that the wireless transmission to the external device is OK, the camera control gain value at the time of photographing the subject is detected. When the camera control gain value is smaller than the reference gain control value A, control is performed so that wireless transmission is performed with normal wireless transmission power X (W), for example, transmission power 1 (W).

  On the other hand, when the camera control gain value is larger than the reference gain control value A and smaller than the reference gain control value B, control is performed so that wireless transmission is performed at Y (W), which is a state in which the transmission power is lowered than usual. To do. For example, control is performed to perform wireless transmission with a transmission power of 0.5 W.

  When the camera control gain value is larger than the reference gain control value B and smaller than the reference gain control value C, the transmission power is further reduced to Z (W), for example, the transmission power is 0.2 W. Control to perform wireless transmission. When the camera control gain value is larger than the reference gain control value C, control is performed so as to stop wireless transmission to the external device.

  In this way, the control gain value at the time of subject shooting is compared with the reference gain control value for performing wireless transmission power control provided in advance in the imaging apparatus. And by controlling the wireless transmission power according to this comparison result, the interference noise is less likely to affect the image in a low illuminance environment where the interference noise is conspicuous in the image, resulting in a reduction in image quality. Can be prevented.

  Here, the camera control gain value detection is performed again while wireless transmission to the external device is being performed with the wireless transmission power reduced in accordance with the camera control gain value at the time of subject shooting. When the camera control gain value changes and shifts from the current transmission power control camera control gain region to another transmission power control gain region, control is performed to change the wireless transmission power.

That is, software (computer program) that realizes the functions of the above-described embodiments is supplied to a system or apparatus via a network or various computer-readable storage media. Then, the computer (or CPU, MPU, etc.) of the system or apparatus reads out and executes the program.
