Abstract

<P>PROBLEM TO BE SOLVED: To perform motion picture photographing at a free angle of view while improving audio without recording noise caused by an operation of varying power of an optical zoom lens and effectively using an angle of view of the optical zoom lens. <P>SOLUTION: In an audio-priority mode, if a motion picture non-compatible optical zoom lens that is not silence-designed is used, it is reported to move the zoom position of the optical zoom lens to a wide-end prior to motion picture photographing, thereby preventing zooming operation from being performed during motion picture photographing. Thus, a video image with excellent audio, in which zoom driving noise is not recorded in the audio, can be obtained. Furthermore, since the zoom position of the optical zoom lens is located in the wide-end during motion picture photographing, the angle of view of the optical zoom lens can be effectively used from the wide-end and by using an electronic zoom, a photographed video image at a free angle of view can be obtained. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to an imaging apparatus capable of capturing moving images with sound, a control method thereof, and a program.

  In recent years, electronic still cameras (hereinafter referred to as electronic cameras) have become widespread. The electronic camera includes an electronic imaging unit that receives a subject image formed by the photographing lens and performs photoelectric conversion, and outputs an image signal of a still image output from the electronic imaging unit and an image corresponding to the image signal. Information or the like can be recorded on a recording medium.

  Conventional electronic cameras have generally taken only still images, but in recent years, the price of semiconductor memory as a recording medium has been reduced, and the signal processing speed inside the camera has been increased. Along with this, it has become relatively easy to record and reproduce simple moving images.

  In addition, some electronic cameras that have been widely used in recent years are configured to have not only a function for recording and reproducing still images and moving images but also a function for recording and reproducing audio information. In this case, the still image, the moving image, and the sound are generally converted into electric signals and then recorded on a predetermined recording medium as data in a predetermined form.

  In general, in an electronic camera, when a shooting operation using a microphone is performed, for example, simultaneous recording is performed at the time of recording a moving image, or memorandum regarding the still image is recorded during or immediately after recording of the still image. For example, voice recording (so-called voice memo) is performed.

  In this type of electronic camera, those equipped with both an optical zoom mechanism and an electronic zoom mechanism have become common. The optical zoom mechanism zooms in an image by enlarging an optical image formed on the imaging surface by changing the focal length of the optical system. The electronic zoom mechanism zooms the video by electronically enlarging a part of the video. In this case, the image zoom is performed by electronic zoom in addition to the optical zoom, whereby the magnification by the optical zoom can be increased by the magnification by the electronic zoom. However, when an image is enlarged by electronic zoom, an image enlarged from a part of the image to the size of the entire image is generated, so that the image quality is deteriorated as compared with an image enlarged only by the optical zoom. Therefore, the conventional electronic camera generally prioritizes the optical zoom when enlarging an image, and generally performs the electronic zoom after the focal point of the optical zoom reaches the tele end (see, for example, Patent Document 1). reference).

  By the way, when shooting a moving image, it is common to record sound at the same time. However, if optical zoom is performed at this time, noise generated by vibration due to driving of an actuator such as a motor or friction when the lens moves inside the lens barrel is recorded as noise of the audio signal. Therefore, Patent Document 2 proposes an electronic camera that performs electronic zooming before optical zooming and prevents noise from being recorded in audio recorded during zooming during moving image shooting.

JP-A-5-300506 JP 2005-175960 A

  However, in the proposal made in Patent Document 2, the zooming operation of the optical zoom is manually performed as in the optical zoom lens of a single-lens reflex type electronic camera (digital single-lens reflex camera) whose photographic lens can be replaced. Not considered. Therefore, when taking a moving image with sound, it is not possible to perform a zooming operation of the optical zoom that generates noise. For example, when the zoom position of the optical zoom is not at the wide end, there is a problem that it cannot be further widened and the angle of view of the optical zoom lens cannot be used effectively.

  In addition, even when an optical zoom lens for moving images that is quiet in the zooming operation of the optical zoom is attached, the electronic zoom is used in preference to the optical zoom when shooting movies, resulting in poor image quality. There is a problem that a moving image is provided to the user.

  Furthermore, in recent years, due to the increase in the number of pixels of the electronic imaging means mounted on the electronic camera, even if all the pixels are used for still image shooting, the pixels are thinned out due to restrictions on the number of pixels in the moving image file format for moving image shooting. In most cases, a moving image with little deterioration in image quality can be obtained even if a part of the video is enlarged by performing electronic zoom.

  The present invention has been made in view of the above problems, and the sound is good without recording noise generated by the zooming operation of the optical zoom lens, and the angle of view of the optical zoom lens is effectively used. The object is to enable video shooting with a free angle of view.

  An imaging apparatus according to the present invention includes an imaging unit that converts an optical image into a video signal, an audio signal acquisition unit that acquires an audio signal, and an optical zoom unit that performs optical zoom on the optical image formed on the imaging unit. And a zoom position detecting means for detecting a zoom position of the optical zoom means, and a video signal converted by the imaging means and an audio signal acquired by the audio signal acquiring means are recorded on a recording medium as a moving image signal with audio. Recording means for controlling, and control means for permitting moving image shooting with sound by the image pickup means and the sound signal acquisition means after the zoom position detection means detects that the zoom position of the optical zoom means is at a predetermined position. It is provided with.

  According to the present invention, the sound is good without recording the noise generated by the zooming operation of the optical zoom unit, and the video angle can be effectively used, and the moving image can be captured at a free angle of view. Is possible.

Reference numeral 1 denotes a camera exterior. Reference numeral 2 denotes a lens holding housing, which detachably holds the photographing lens 3 via a closely fixed mount 2a. The lens holding housing 2 also holds a shutter 5, an AF sensor 8, a main mirror 4 and the like which will be described later. The mount 2a has an interface unit for communicating various signals with the photographing lens 3 and supplying drive power.

  Reference numeral 3 denotes an interchangeable photographic lens, which is an optical zoom lens. Here, the photographing lens 3 is a moving image non-capable photographing lens in which the zooming operation sound of zoom is not designed to be quiet. Inside the photographic lens 3 are a focus lens group and a zoom lens group 3a which is an optical zoom means, a diaphragm device 3b comprising a plurality of diaphragm blades, and a focal length which is a zoom position detection means for detecting the zoom position of the zoom lens group 3a. It has an encoder 3c. In FIG. 1, each lens group is illustrated as a single lens for convenience, but in actuality, it is configured by a complex combination of lens groups by a large number of lenses. The zoom lens group 3a is driven via a cam mechanism (not shown) by manually rotating (zooming) a zoom ring (not shown) arranged in a ring shape on the exterior of the photographing lens 3. At this time, a driving sound such as a frictional sound is generated from the zoom ring and the cam mechanism and transmitted to the mount 2a and the lens holding housing 2 which are in close contact with the photographing lens 3. The transmitted sound is collected and recorded as noise by an audio recording microphone 15 described later.

  A microcomputer (not shown) (central processing unit: hereinafter referred to as MPU), which is a control means for controlling the entire camera, can communicate with the photographic lens 3 via the mount 2a. Thereby, the zoom position of the zoom lens group 3a can be detected at an arbitrary timing from the signal obtained from the focal length encoder 3c. Further, it is possible to detect whether the photographing lens 3 is a single focus lens, a zoom lens, or a moving image compatible lens designed to be quiet.

  Reference numeral 4 denotes a main mirror composed of a half mirror, which can be rotated according to the operating state of the camera. The main mirror 4 is obliquely provided in the photographing optical path when the subject is observed with the finder, and bends the light beam from the photographing lens 3 and guides it to the finder optical system described later. Further, when photographing or in a live view state described later, the light is retracted from the photographing optical path and the light flux from the photographing lens 3 is guided to the image sensor 6 described later.

  Reference numeral 5 denotes a shutter, which controls the incidence of a light beam from the photographing lens 3 to the image sensor 6. The shutter 5 is open during still image, moving image shooting, and live view states, and the light beam enters the image sensor 6. Reference numeral 6 denotes an image pickup device which is an image pickup means using a CMOS sensor, for example, which converts and accumulates a light beam transmitted through the photographing lens 3 into an image signal.

  Reference numeral 7 denotes a sub-mirror that rotates together with the main mirror 4. The sub mirror 7 bends the light beam transmitted through the main mirror 4 and guides it to an AF sensor 8 to be described later when the main mirror 4 is obliquely provided in the photographing optical path. Further, when the main mirror 4 is retracted from the photographing optical path, it is retracted together and the light flux is guided to the image sensor 6. Reference numeral 8 denotes an AF sensor, which includes a secondary imaging lens, an area sensor including a plurality of CCDs, and the like, and can detect a focus by a known phase difference method.

  Reference numeral 9 denotes a focusing plate disposed on the primary image forming surface of the photographic lens 3. A Fresnel lens (condenser lens) is provided on the incident surface, and a subject image (finder image) is formed on the exit surface. Reference numeral 10 denotes a finder optical path changing pentaprism that corrects a subject image formed on the exit surface of the focusing plate 9 into an erect image. Reference numerals 11 and 12 are eyepiece lenses. Here, an optical system including the focus plate 9, the pentaprism 10, and the eyepieces 11 and 12 is referred to as a finder optical system. Reference numeral 13 denotes an AE sensor, which is composed of photodiodes corresponding to the respective areas in the multi-divided shooting screen, and measures the luminance of the subject image formed on the exit surface of the focusing screen 9.

  A liquid crystal monitor 14 displays captured images and various types of shooting information. Reference numeral 15 denotes an audio recording microphone which is an audio signal acquisition means, which collects audio around the camera during audio recording of the camera and acquires an audio signal. There is an opening in the camera exterior 1 at a position opposite to the sound recording microphone 15 so that sound around the camera can be collected effectively. Reference numeral 16 denotes a recording device as recording means, which writes a moving image signal with sound to a recording medium such as a media card.

  FIG. 2 is a block diagram illustrating a basic configuration for shooting a moving image with sound of the digital single-lens reflex camera according to the first embodiment. When the start of moving image shooting is instructed by the photographer, the audio signal obtained from the audio recording microphone 15 is digitally converted by an A / D converter (not shown) and input to the amplifier 203 through the audio filter 202. Here, the sound filter 202 is set to a frequency characteristic suitable for sound. The gain of the amplifier 203 is controlled to an appropriate level by the gain control circuit 207. The audio signal output from the amplifier 203 is converted into an audio file format by the signal processing circuit 204.

  At the same time, in FIG. 1, both the main mirror 4 and the sub mirror 7 are rotated upward to retract from the photographing optical path, and the shutter 5 is opened, and the light image from the photographing lens 3 is guided to the image sensor 6. The image sensor 6 converts an optical image into an image signal, and the acquired image signal is digitally converted by an A / D converter 209.

  The memory controller 205 associates an audio file format with the image signal digitally converted by the A / D converter 209 to generate a moving image signal with audio and transmits it to the recording device 16 for writing to the recording medium.

  Next, the operation of the digital single-lens reflex camera according to the first embodiment when shooting moving images with sound will be described. FIG. 3 is a rear view of the digital single-lens reflex camera according to the first embodiment. 21 is a power switch, 22 is a live view button, 23 is a moving image button, 24 is an electronic zoom-in button, and 25 is an electronic zoom-out button. The movie button 23 lights in red at the center in the movie standby state, informs the photographer that movie shooting is in the standby state, blinks red in the center during movie shooting, and is shooting movie to the photographer Let me know.

  FIG. 4 is a flowchart showing a detailed operation at the time of moving image recording with sound of the digital single lens reflex camera according to the first embodiment. The flowchart shown in FIG. 4 is realized by the MPU executing a control program. In step S101, the photographer operates the power switch 21 to turn on the camera. In step S102, when the photographer operates the live view button 22, the process proceeds to step S103, and the MPU determines whether the mode setting state of the camera is the voice priority mode. If it is in the voice priority mode, the process proceeds to step S104. If it is not the voice priority mode, the process proceeds to step S117, and normal moving image shooting is performed. Here, normal moving image shooting refers to shooting that allows zoom operation of the shooting lens 3. In this case, when an optical zoom lens that is not designed to be quiet and does not support moving images is used, the zoom drive sound may be recorded in the sound as noise.

  In steps S104 and S105, the MPU determines whether or not the photographing lens 3 attached to the mount 2a is a moving image compatible lens or a single focus lens. If the lens is a moving image compatible lens or a single focus lens, no zoom driving sound is generated, and the process proceeds to step S117 (normal moving image shooting that allows zoom operation during moving image shooting).

  When the photographing lens 3 is an optical zoom lens that does not support moving images in steps S104 and S105, the process proceeds to step S106, and the MPU instructs the liquid crystal monitor 14 to, for example, “operate the zoom lens / zoom lens that does not support moving images to the wide side”. And display a notification.

  In step S107, the MPU determines whether or not the zoom position of the photographing lens 3 has been operated to the wide side by the photographer and the zoom position is at the wide end (wide angle end). If the zoom position is at the wide end, the process proceeds to step S108 as permitting moving image recording with sound. As described above, the MPU can detect the zoom position of the zoom lens group 3a at an arbitrary timing by communicating with the photographing lens 3 via the mount 2a.

  In step S108, a predetermined operation is performed to enter a live view state, and a through image obtained by converting the light beam transmitted through the photographing lens 3 into a video signal by the image sensor 6 is displayed on the liquid crystal monitor 14.

  In step S109, the central portion of the moving image button 23 is lit red to notify the photographer that moving image shooting is in a standby state. In step S110, the MPU determines whether or not the moving image button 23 has been pressed by the photographer. If the moving image button 23 has been pressed, the MPU proceeds to step S111 and starts moving image shooting by a predetermined operation. In step S112, the central portion of the moving image button 23 blinks red to notify the photographer that moving image shooting is in progress.

  In step S113, the MPU always determines whether or not the zoom position is at the wide end during moving image shooting. When it is detected that the zoom position is not at the wide end, it is determined that the photographer has performed the zoom operation, and the process proceeds to step S118. For example, “Please do not zoom the lens / operate the lens to the wide side”. Please display a warning. The photographer continues to display the warning until the photographer operates the zoom position to the wide end and again detects the wide end in step S113.

  Although not shown in the flowchart, the electronic zoom operation during moving image shooting can be performed by operating the electronic zoom-in button 24 and the electronic zoom-out button 25. The electronic zoom buttons 24 and 25 are designed to be quiet, so that the operation sound is not recorded in the sound even if it is operated during moving image shooting.

  In step S114, it is determined whether or not the moving image button 23 has been pressed again by the photographer. If the moving image button 23 has been pressed again, the process proceeds to step S115, and the red flashing at the center of the moving image button 23 is turned off. Thereafter, in step S116, the moving image shooting is terminated by a predetermined operation.

  As described above, in the audio priority mode, when using an optical zoom lens that is not designed to be quiet and does not support moving images, the zoom position of the optical zoom lens must be operated to the wide end before shooting a movie. Some zoom operations can be avoided. As a result, it is possible to obtain an image with good sound without recording the zoom driving sound in the sound.

  During movie shooting, the zoom position of the optical zoom lens is at the wide end, so the field angle of the optical zoom lens can be used effectively from the wide end. Can be obtained.

  In this embodiment, when it is detected that the zoom position is not at the wide end during moving image shooting, a warning is displayed on the liquid crystal monitor. However, when it is detected that the zoom position is not at the wide end, moving image shooting may be stopped. Further, although it is detected whether or not the zoom position of the optical zoom lens is at the wide end, it may be detected that the zoom position is not at the wide end but at a certain zoom position. In this case, the angle of view of the optical zoom lens cannot be effectively used from the wide end, but an image with less deterioration in image quality can be obtained by using the optical zoom than using the electronic zoom.

The photographing lens 42 includes a zoom lens group 42a, a diaphragm device 42b, a focal length encoder 42c, and a zoom drive mechanism 42d. The zoom lens group 42a is a focus lens group or optical zoom means. The diaphragm device 42b is composed of a plurality of diaphragm blades. The focal length encoder 42c is zoom position detecting means for detecting the zoom position of the zoom lens group 42a. The zoom drive mechanism 42d is a drive unit that drives the zoom lens group 42a. In FIG. 5, each lens group is illustrated as a single lens for convenience, but in actuality, it is configured by a complex combination of lens groups by a large number of lenses. When the zoom lens group 42a is driven by the zoom lens driving mechanism 42d, a driving sound such as a frictional sound is generated from a mechanical mechanism such as a cam or a gear, and a sound recording microphone 44 described later collects and records the noise as noise. .

  A microcomputer (not shown) (central processing unit: hereinafter referred to as MPU), which is a control means for controlling the entire camera, determines the zoom position of the zoom lens group 42a at an arbitrary timing from a signal obtained from the focal length encoder 42c. Can be detected.

  A zoom lever 43 is rotatably disposed on the camera exterior 40, and can be rotated optically or electronically during silent moving image shooting by rotating clockwise and counterclockwise. 47 is a shutter button.

  An audio recording microphone 44 is an audio signal acquisition unit that collects audio around the camera and acquires an audio signal when the audio is recorded by the camera. There is an opening in the camera exterior 40 at a position opposite to the sound recording microphone 44 so that sound around the camera can be collected effectively.

  Reference numeral 45 denotes an image pickup element which is an image pickup means using a CMOS sensor, for example, which converts and accumulates a light beam transmitted through the photographing lens 42 into an image signal.

  Reference numeral 46 denotes a recording device as recording means, which writes a moving image signal with sound to a recording medium such as a media card.

Write the attached video signal to the media card.

  Reference numeral 51 denotes a shooting mode switch, which can switch the shooting mode when the camera is in a shooting state between a moving image shooting mode and a still image shooting mode. A liquid crystal monitor 52 displays captured images and various types of shooting information. Reference numeral 53 denotes a moving image button for instructing the start and end of the moving image. The movie button 53 is lit red in the center in the movie standby state, informs the photographer that movie shooting is in the standby state, and blinks in red in the center during movie shooting, and is shooting the movie to the photographer. Let me know.

  Next, an operation of the digital camera according to the second embodiment when shooting a moving image with sound will be described. FIG. 7 is a flowchart showing a detailed operation of the digital camera according to the second embodiment when shooting a moving image with sound. The flowchart shown in FIG. 7 is realized by the MPU executing a control program. In step S201, when the power switch 41 is operated by the photographer and the camera is turned on, the photographing lens 42 is extended a predetermined amount. The photographing lens 42 is an optical zoom lens having an optical zoom mechanism capable of changing the photographing range.

  In step S202, the MPU determines whether or not the shooting mode switch 51 is set to the moving image mode. If the moving image mode is set, the process advances to step S203 to perform a predetermined operation, start a live view, and display a through image on the liquid crystal monitor 52. If the moving image mode is not set, the still image mode is set, so that the process proceeds to step S214 and normal still image shooting is performed.

  In step S204, the MPU determines whether the mode setting state of the camera is the voice priority mode. If it is in the voice priority mode, the process proceeds to step S205. If not in the voice priority mode, the process proceeds to step S215, and normal moving image shooting is performed. Here, normal moving image shooting refers to shooting that allows zoom operation of the shooting lens 42. In this case, the zoom drive sound may be recorded in the sound as noise.

  In steps S205 and S206, the MPU drives the zoom lens group 42a by the zoom drive mechanism 42d, and drives until the zoom position reaches the wide end. If the zoom position is at the wide end, the process proceeds to step S207 as permitting moving image shooting with sound.

  In step S207, the central portion of the moving image button 53 is lit red to notify the photographer that moving image shooting is in a standby state. In step S208, the MPU determines whether or not the moving image button 53 has been pressed by the photographer. If the moving image button 53 has been pressed, the MPU proceeds to step S209 and starts moving image shooting by a predetermined operation. In step S210, the central portion of the moving image button 53 blinks red to notify the photographer that moving image shooting is in progress. During moving image shooting, audio around the camera is collected by the audio recording microphone 44 and converted into an audio signal. Also, the moving image signal acquired by the image sensor 45 is digitally converted by an A / D converter, converted into a moving image signal with sound associated with the sound signal simultaneously recorded by the memory controller, and the media card by the recording device 46. Is written to.

  Although not shown in the flowchart, the electronic zoom operation during moving image shooting can be performed by rotating the zoom lever 43 clockwise and counterclockwise. The optical zoom operation is not performed. The zoom lever 43 is designed to be quiet, and no operation sound is recorded in the sound even if it is operated during moving image shooting.

  In step S211, it is determined whether or not the moving image button 53 has been pressed again by the photographer. If the moving image button 53 has been pressed again, the process proceeds to step S212, and the red flashing at the center of the moving image button 53 is turned off. Thereafter, in step S213, the moving image shooting is terminated by a predetermined operation.

  As described above, in the audio priority mode, the zoom position of the optical zoom lens is driven to the wide end before shooting a movie, and the zoom operation is not performed during movie shooting. It is possible to obtain an image with good sound that is not performed.

  During movie shooting, the zoom position of the optical zoom lens is at the wide end, so the field angle of the optical zoom lens can be used effectively from the wide end. Can be obtained.

  In this embodiment, it is detected whether or not the zoom position of the optical zoom lens is at the wide end, but it may be detected that the zoom position is not at the wide end but at a certain zoom position. In this case, the angle of view of the optical zoom lens cannot be effectively used from the wide end, but an image with less deterioration in image quality can be obtained by using the optical zoom than using the electronic zoom.
