Abstract

<P>PROBLEM TO BE SOLVED: To achieve guide display appropriate to a photographing condition. <P>SOLUTION: A guide display production control section 109 captures a tilt detection signal, and then captures a shake signal output judgement signal from a shake signal output judgement section 114. Subsequently, the control section 109 determines whether photographing is carried out with a video camera fixed in position or held with hands. If photographing with the video camera held with hands is to be carried out, the control section 109 determines whether the tilt of the video camera is a set value α (>β) or above. If it is the set value α or above, the guide display is set ON. If the tilt is less than the set value α, it is set OFF. If photographing with the video camera fixed in position is to be carried out, the control section 109 determines whether the tilt of the video camera is a set value β or above. If it is the set value β or above, the guide display is set ON. If the tilt is less than the set value β, it is set OFF. Thus, photographing with the video camera fixed in position can be set small in the set value for a tilt according to which the guide display is set ON or OFF, compared with photographing with the video camera held with hands. Accordingly, in photographing with the video camera fixed in position, in which case tilt may be more likely to occur, the guide display is given for a smaller tilt. <P>COPYRIGHT: (C)2008,JPO&INPIT

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.
(First embodiment)
FIG. 1 is a block diagram showing a schematic configuration of a video camera according to the first embodiment. Reference numeral 101 denotes a lens unit for photographing a subject. A CCD 102 photoelectrically converts a subject image formed by the lens unit 101.

  Reference numeral 103 denotes a camera signal processing circuit, which converts an analog imaging signal into a digital signal by a built-in A / D converter, performs predetermined signal processing such as gamma correction and white balance, and is finally standardized Generate a video signal.

  A display processing circuit 104 superimposes and outputs a guide display signal (to be described later) on the output video signal from the camera signal processing circuit 103 and displays it on the display device 105. Reference numeral 105 denotes a display device such as a viewfinder or a liquid crystal panel.

  Reference numeral 106 denotes an inclination detection sensor for detecting the inclination of the video camera, and is constituted by, for example, an acceleration sensor. Reference numeral 107 denotes an amplifier circuit that amplifies the output of the tilt detection sensor 106.

  Reference numeral 111 denotes a shake detection sensor for detecting the shake of the video camera, and is constituted by an angular velocity sensor, for example. Reference numeral 112 denotes a high-pass filter (HPF) that removes a DC component from the output of the shake detection sensor 111. Reference numeral 113 denotes an amplifier circuit that amplifies the output of the HPF 112.

  Reference numeral 108 denotes a camera system control microcomputer (hereinafter abbreviated as “microcomputer”), which includes a camera control unit 110, a guide display generation control unit 109, and a shake signal output determination unit 114. The camera control unit 110 performs drive control of the CCD 102 and the camera signal processing circuit 103. The guide display generation control unit 109 takes in the output of the amplifier circuit 107, generates a guide display signal corresponding to the detected inclination, and outputs it to the display processing circuit 104. The guide display generation control unit 109 controls the output of the guide display signal based on the control signal from the shake signal output determination unit 114. The shake signal output determination unit 114 compares the frequency of the output of the amplifier circuit 113 with a predetermined threshold, determines whether or not the state exceeding the threshold continues for a predetermined time, and guides the control signal from the determination result. Output to the generation control unit 109.

  In the video camera of the present embodiment, incident light that has passed through the lens unit 101 forms an optical image on the imaging surface of the CCD 102 and is photoelectrically converted by the CCD 102. In the camera signal processing circuit 103, the output of the CCD 102 is subjected to A / D conversion, predetermined signal processing such as gamma correction and white balance, and then output as a standardized video signal. The output video signal from the camera signal processing circuit 103 is supplied to the display device 105 via the display processing circuit 104 and is monitored as a captured image.

  Next, video camera tilt detection and guide display generation will be described. The tilt detection sensor 106 outputs a detection signal based on the tilt of the video camera. The output of the inclination detection sensor 106 is amplified by a predetermined amount by the amplifier circuit 107 and input to the microcomputer 108 as an inclination detection signal. Based on the tilt detection signal input to the microcomputer 108, the guide display generation control unit 109 generates a guide display signal corresponding to the tilt of the video camera. The guide display signal is also controlled using the shake signal output determination unit 114. The guide display signal output from the guide display generation control unit 109 is supplied to the display device 105 via the display processing circuit 104.

  Next, shake components applied to the video camera will be described. The shake detection sensor 111 outputs a shake detection signal based on the shake of the video camera. The output of the shake detection sensor 111 is amplified by a predetermined amount by the amplifier circuit 113 after the direct current component is removed by the HPF 112 and input to the microcomputer 108 as a shake detection signal. Based on the shake detection signal input to the microcomputer 108, the shake signal output determination unit 114 determines the state of the shake detection signal. Specifically, the shake signal output determination unit 114 calculates a frequency from the input shake detection signal, compares the frequency with a predetermined threshold value, and determines whether or not the set time is continued in a state where the threshold value is exceeded. To do. The frequency threshold may be set so that a camera shake frequency component (for example, 5 [Hz] or more) can be detected.

  Here, calculation of the frequency from the shake detection signal will be described. The calculation of the frequency is performed by counting the number of times the fluctuation detection signal is folded back and forth per unit time. For example, the number of times of folding per cycle per unit time is 2 [1] Hz, that is, the frequency is ½ of the number of times of folding. Therefore, when the number of times of folding is 10, “10/2 = 5”. The frequency [Hz] is calculated.

  FIG. 5 is a characteristic diagram showing shake detection signals during hand-held shooting with a video camera and during fixed shooting with a tripod or the like. 5A and 5B, the vertical axis represents a shake detection signal, and the horizontal axis represents time. A characteristic line 501 in FIG. 5A is a shake detection signal at the time of hand-held shooting, and is a signal component in which the fluctuation of the output fluctuation of the shake detection signal is continuously turned up and down and the frequency of the shake can be detected. On the other hand, the characteristic line 501 ′ in FIG. 5B is a shake detection signal at the time of fixed imaging, and the fluctuation of the output of the shake detection signal is minute, and the return of increase / decrease is discontinuous. Is a signal component that is difficult to detect. From such a difference in shake detection signals, it can be determined whether the video camera is in a hand-held shooting state or a fixed shooting state.

  Based on the determination result, the shake signal output determination unit 114 causes the guide display generation control unit 109 to output a shake signal output determination signal that is binarized (Lo, Hi) as to whether the camera is in the handheld shooting state or the fixed shooting state. Supplied as a control signal. In other words, if the frequency of the shake detection signal is continuously input for a set time with the frequency exceeding the threshold, the shake signal output determination signal (Lo) is output as handheld shooting. On the other hand, when the frequency of the shake detection signal exceeds the threshold value and is not input continuously for a set time, the shake signal output determination signal (Hi) is output assuming that fixed shooting has been performed. There is no problem even if the logic of the control signal is reversed.

  Next, the guide display signal output control executed in the microcomputer 108 will be described with reference to the flowchart of FIG. FIG. 2 is a flowchart for explaining the processing operation executed by the guide display generation control unit 109 of the microcomputer 108. First, in step S <b> 201, an inclination detection signal is taken from the inclination detection sensor 106 through the amplifier circuit 107.

  Next, in step S209, a shake signal output determination signal is fetched from the shake signal output determination unit 114. In step S202, the shake signal output determination signal captured in step S209 is determined. If fixed shooting, the process proceeds to step S206, and if handheld shooting, the process proceeds to step S203.

  In the case of handheld shooting, in step S203, it is determined whether or not the tilt of the video camera is equal to or greater than a set value α. If the inclination is not less than the set value α, the guide display is set to ON in step S204. On the other hand, if the inclination is less than the set value α, the guide display is set to OFF in step S207.

  On the other hand, in the case of fixed shooting, in step S206, it is determined whether or not the tilt of the video camera is greater than or equal to the set value β. If the inclination is greater than or equal to the set value β, the guide display is set to ON in step S204. On the other hand, if the inclination is less than the set value β, the guide display is set to OFF in step S207.

  In step S205, a display instruction is given to the display processing circuit 104. In other words, after step S204, a guide display signal is generated and output, and is superimposed on the output video signal from the camera signal processing circuit 103 (guide display display). In contrast, when step S207 is performed, the guide display signal is not superimposed on the output video signal from the camera signal processing circuit 103 (the guide display is not displayed).

  Here, the relationship between the setting value α and the setting value β is α> β, and the setting value of the inclination for turning on / off the guide display is set smaller in the fixed shooting than in the handheld shooting. . That is, during fixed shooting where the tilt is conspicuous, the guide display is made for a smaller tilt.

  In the present embodiment, it is determined that the camera is in the handheld shooting state when the output frequency of the shake detection sensor 111 exceeds the threshold and the setting time is not continued, and the fixed shooting state is detected when the setting time is continued. However, the shooting state may be determined based on the amplitude of the output of the shake detection sensor 111.

  Furthermore, in this embodiment, the shake state of the video camera is detected by the shake detection sensor 111, but the shake state is detected from a shake change signal obtained by band-limiting the detection signal of the tilt detection sensor 106 or a motion vector detected from the captured image. Can also be detected.

  FIG. 3 is a diagram illustrating the relationship between the tilt of the video camera and the output of the tilt detection sensor (acceleration sensor) 106. In FIG. 3, reference numeral 100 denotes a video camera, 105 denotes a liquid crystal panel as a display device, and 106 denotes a tilt detection sensor. By appropriately setting the gain setting of the amplifier circuit 107, the output of the inclination detection sensor 106 can be set to take the following voltage range.

FIG. 3B shows a state where the video camera is in the normal position. In this state, the output of the inclination detection sensor 106 is half of the power supply voltage _Vcc . On the other hand, when the video camera 100 is tilted 90 degrees to the right as shown in FIG. 3A, the output of the tilt detection sensor 106 becomes the same as the power supply voltage _Vcc . Conversely, as shown in FIG. 3 (c), when tilted 90 degrees to the left, the output of the tilt detection sensor 106 becomes the GND level.

  In the middle inclination between FIG. 3 (a) and FIG. 3 (b), FIG. 3 (b) and FIG. 3 (c), the output of the inclination detection sensor 106 changes linearly with respect to the inclination. Therefore, if a predetermined voltage threshold is provided for the output at the normal position shown in FIG. 3B, it can be determined whether or not the predetermined angle is exceeded. In other words, by switching the voltage threshold of the sensor output between hand-held shooting and fixed shooting, it is possible to set a setting value for the inclination for turning on / off the guide display. If the orientation of the tilt detection sensor 106 is reversed, the sensor output voltage when the video camera is tilted is opposite to that shown in FIG.

  FIG. 4 shows a range where the guide display is displayed on the display device 105. As described above, by switching the voltage threshold of the sensor output between the hand-held shooting and the fixed shooting, as shown in FIG. 4, the region where the guide display in the fixed shooting is turned off is narrower than that in the hand-held shooting. be able to. This makes it possible to recognize the tilt of the video camera more quickly when it is fixed to a tripod or the like.

  As described above, the guide display can be performed in a manner suitable for the shooting state by detecting the shake of the video camera and changing the setting value of the tilt for turning the guide display ON / OFF. In other words, during hand-held shooting, by widening the area where the guide display is turned off, the photographer is too aware of the tilt of the camera and the framing is disturbed, or the monitor display always feels complicated due to the guide display moving constantly. This has the effect of preventing shooting and reducing the hindrance to shooting. On the other hand, at the time of fixed shooting, by narrowing the area where the guide display is turned off, the photographer corrects the tilt of the video camera based on the guide display, thereby improving the shooting accuracy.

(Second Embodiment)
A second embodiment of the present invention will be described. The configuration of the video camera of the second embodiment is the same as that of the first embodiment, and detailed description thereof is omitted here.

  FIG. 6 is a flowchart for explaining the processing operation executed by the guide display generation control unit 109 of the microcomputer 108. First, in step S <b> 601, an inclination detection signal is taken from the inclination detection sensor 106 via the amplifier circuit 107.

  Next, in step S <b> 609, a shake signal output determination signal is captured from the shake signal output determination unit 114.

  Next, in step S602, it is determined whether or not the tilt of the video camera is greater than or equal to a set value α. If the inclination is not less than the set value α, the guide display is set to ON in step S603. On the other hand, if the inclination is less than the set value α, the guide display is set to OFF in step S607.

  In step S604, the shake signal output determination signal fetched in step S609 is determined. If it is fixed shooting, the process proceeds to step S605 to increase the display sensitivity. This is an operation for exaggerating the guide display. On the other hand, if it is handheld shooting, the process proceeds to step S606, and the display sensitivity (exaggeration level) is set to the normal setting.

  In step S608, a display instruction is given to the display processing circuit 104. That is, when step S603 is performed, a guide display signal is generated and output, and the guide display is superimposed on the output video signal from the camera signal processing circuit 103 (display of guide display). On the other hand, when step S607 is performed, the guide display is not superimposed on the output video signal from the camera signal processing circuit 103 (the guide display is not displayed).

  FIG. 7 shows a guide display when the display sensitivity is changed in the second embodiment. As can be seen from FIG. 7, even when the tilt of the video camera with respect to the horizontal position is the same, the guide display is exaggerated in the fixed shooting compared to the handheld shooting (in other words, the guide display does not change even when the tilt is the same). It can be seen that it is displayed). As described above, the guide display is exaggerated during fixed shooting, whereby the tilt of the video camera becomes clearer and the photographer can easily recognize. In addition, since it becomes easy to understand the change in the inclination with respect to a minute movement during fixed shooting, it becomes easier to align the horizontal state.

  As described above, by detecting the shake of the video camera and changing the display sensitivity (exaggeration level) of the guide display, the guide display can be performed in a form suitable for the shooting state. In other words, in fixed shooting, the display sensitivity (exaggeration level) is increased compared to hand-held shooting and the guide display is exaggerated, which makes it easier for the photographer to understand the tilt of the video camera during fixed shooting where the tilt of the shooting result is noticeable. I can inform you. Furthermore, since the amount of displacement of the tilt of the video camera with respect to the delicate tilt can be clearly understood, the horizontal state can be easily adjusted.

(Third embodiment)
A third embodiment of the present invention will be described. The basic configuration of the video camera of the third embodiment is the same as that shown in FIG. 1, but as shown in FIG. 8, a gain variable amplifier circuit 801 capable of changing the gain is provided instead of the amplifier circuit 107.

  The microcomputer 802 of this embodiment further includes a gain control unit 803 that changes the gain of the variable gain amplifier circuit 801.

  FIG. 10 is a diagram illustrating a configuration example of the gain variable amplifier circuit 801. The variable gain amplifier 801 includes an amplifier 805, a resistor 806, and a gain changeover switch 804. In response to the switch switching signal from the camera control microcomputer 802, the input resistor 806 of the amplifier 805 is connected in parallel, and the amplifier gain is increased. This gain change is performed to exaggerate the guide display during fixed shooting.

  FIG. 9 is a flowchart for explaining processing operations executed by the guide display generation control unit 109 and the gain control unit 803 of the microcomputer 802. First, in step S <b> 901, a tilt detection signal is taken from the tilt detection sensor 106 via the variable gain amplifier circuit 801.

  Next, in step S <b> 911, a shake signal output determination signal is captured from the shake signal output determination unit 114. In step S902, the shake signal output determination signal fetched in step S911 is determined. If it is fixed shooting, the process proceeds to step S903, and if it is handheld shooting, the process proceeds to step S909.

  In the case of fixed shooting, it is checked in step S903 whether or not the sensor sensitivity is increased. Here, it is determined whether or not the gain of the variable gain amplifier circuit 801 is set high. If the sensor sensitivity has increased in step S903, the process proceeds to step S904. If the sensor gain has not increased, the gain is set to increase in step S908 so as to increase the sensor sensitivity.

  On the other hand, in the case of handheld shooting, it is checked in step S909 whether the sensor sensitivity is set to normal. If the sensor sensitivity is not a normal setting in step S909, that is, if it is a setting for fixed shooting, the sensor sensitivity is changed to a normal setting in step S910. This is an operation for turning off the gain changeover switch 704 in the variable gain amplifier circuit 801. If the sensor sensitivity is a normal setting in step S909, the process proceeds to step S904.

  In step S904, it is determined whether or not the tilt of the video camera is greater than or equal to a set value α. If the inclination is not less than the set value α, the guide display is set to ON in step S905. On the other hand, if the inclination is less than the set value α, the guide display is set to OFF in step S907.

  In step S906, a display instruction is given to the display processing circuit 104. That is, when step S905 is performed, a guide display signal is generated and output, and the guide display is superimposed on the output video signal from the camera signal processing circuit 103 (guide display display). On the other hand, when step S907 is performed, the guide display is not superimposed on the output video signal from the camera signal processing circuit 103 (the guide display is not displayed).

  As described above, by detecting the shake of the video camera and changing the sensor sensitivity of the tilt detection sensor 106, guide display can be performed in a form suitable for the shooting state. That is, at the time of fixed shooting, the gain of the gain variable amplifier circuit 801 is changed to be higher than that at the time of hand-held shooting, so that the tilt of the video camera is fixed at the time of fixed shooting where the inclination of the shooting result is conspicuous as in the second embodiment. It is possible to inform the photographer more clearly. Furthermore, since the amount of displacement of the tilt of the video camera with respect to the delicate tilt can be clearly understood, the horizontal state can be easily adjusted.

(Fourth embodiment)
A fourth embodiment of the present invention will be described. In the fourth embodiment, as described in the first and second embodiments, the setting value of the tilt for turning on / off the guide display is changed and fixed between the hand-held shooting and the fixed shooting. When shooting, the display sensitivity is increased and the guide display is exaggerated. The configuration of the video camera of the fourth embodiment is the same as that of the first and second embodiments, and detailed description thereof is omitted here.

  FIG. 11 is a flowchart for explaining the processing operation executed by the guide display generation control unit 109 of the microcomputer 108. First, in step S <b> 1101, an inclination detection signal is captured from the inclination detection sensor 106 via the amplifier circuit 107.

  Next, in step S <b> 1109, a shake signal output determination signal is fetched from the shake signal output determination unit 114. In step S1102, the shake signal output determination signal captured in step S1109 is determined. If fixed shooting, the process proceeds to step S1103. If handheld shooting, the process proceeds to step S1106.

  In the case of fixed shooting, it is determined in step S1103 whether or not the tilt of the video camera is equal to or greater than a set value β. If the inclination is equal to or larger than the set value β, the guide display is set to ON in step S1104, and processing for further increasing the display sensitivity (exaggeration level) is performed. On the other hand, if the inclination is less than the set value β, the guide display is set to OFF in step S1108.

  On the other hand, in the case of handheld shooting, it is determined in step S1106 whether or not the tilt of the video camera is equal to or greater than a set value α. If the inclination is equal to or greater than the set value α, guide display is set to ON in step S1107, and processing for setting the display sensitivity to the normal state is performed. On the other hand, if the inclination is less than the set value α, the guide display is set to OFF in step S1108.

  In step S1105, a display instruction is given to the display processing circuit 104. That is, when steps S1104 and S1107 are performed, a guide display signal is generated and output, and the guide display is superimposed on the output video signal from the camera signal processing circuit 103 (guide display display). In contrast, when step S1108 is performed, the guide display is not superimposed on the output video signal from the camera signal processing circuit 103 (the guide display is not displayed).

  In summary, when the fixed shooting is performed and the tilt is less than the set value β in step S1103, or when the handheld shooting is performed and the tilt is less than the set value α in step S1106, the video is recorded. The camera is substantially horizontal, and the guide display is set to OFF in step S1108.

  Here, the relationship between the set value α and the set value β is set so that α> (display sensitivity magnification × β). The tilt setting value for turning on the guide display is always smaller in fixed shooting than in handheld shooting, and the guide display in fixed shooting becomes exaggerated as the tilt of the video camera increases. .

  As described above, the guide display when the video camera is tilted is performed with a small tilt at the time of fixed shooting where the tilt is easily noticeable, so that the photographer can be notified of the tilt of the camera quickly. At the same time, when the tilt is large, the guide display is exaggerated than the actual tilt, so that the tilt of the video camera becomes clearer. Furthermore, since the change in the inclination with respect to a minute movement becomes easy to understand, the horizontal state can be more easily matched and the horizontal accuracy can be improved.
