Description

  The present invention relates to an imaging apparatus, and more particularly to an imaging apparatus having a macro imaging function.

  Some cameras as imaging devices have a built-in strobe on the front surface or upper surface of the camera body as illumination means for irradiating the subject with illumination light. When performing so-called macro photography in which a close subject is photographed by such a camera, a lens barrel having an imaging lens supported therein is extended forward and protrudes greatly from the main body. For this reason, even if the strobe is turned on, a part of the illumination light is blocked by the front end of the lens barrel, and a so-called light spilling state occurs, making it difficult to uniformly illuminate the entire subject. It was.

  In order to eliminate such problems, for example, Japanese Patent Laying-Open No. 2005-301217 (Patent Document 1) discloses a technique of providing a light emitting member at the tip of a lens barrel. In the digital camera described in Patent Document 1, four light emitting diodes as light emitting elements are embedded and arranged at equiangular intervals at the tip of a lens barrel. The light emitting diode is configured such that when a release button is pressed deeply and a shutter release operation is performed, power is supplied in synchronization with the opening operation of the shutter to emit light.

JP 2005-301217 A

  In the digital camera described in Patent Document 1, a light emitting diode as a light emitting element does not need a bulky member such as a booster circuit such as a DC / DC converter or a large-capacitance capacitor unlike a strobe. It can be housed and installed compactly at the tip.

  On the other hand, since the light emitting diode has a smaller amount of light than the strobe, in order to uniformly illuminate the entire subject, a plurality of light emitting diodes are arranged at positions where light is irradiated from a plurality of different directions. There is a need. For this reason, it is not possible to sufficiently satisfy the demand for low power consumption and low cost.

  Therefore, the present invention has been made to solve such a problem, and an object of the present invention is to efficiently distribute light emitted from a light emitting member to a subject, thereby reducing power consumption, downsizing, and low power. An object of the present invention is to provide an imaging apparatus capable of reducing costs.

  Preferably, the light emitting member includes at least one light emitting element disposed at a distal end portion of the lens barrel. The reflecting member is disposed at the tip of the lens barrel, and has a scattering reflection surface for scattering and reflecting the return light forward on at least a part of the surface thereof.

  Preferably, the light emitting member includes at least one light emitting element disposed at a distal end portion of the lens barrel. The reflecting member is disposed at the tip of the lens barrel, and has an inclined reflecting surface for reflecting the return light toward the subject on at least a part of the surface thereof.

FIG. 2 is a plan view schematically showing a state in which macro photography is performed by emitting light from a light emitting member in the digital camera of FIG. It is a figure which shows schematic structure when the digital camera according to the modification 1 of embodiment of this invention is seen from the front (object side). It is AA sectional drawing of FIG. It is a figure which shows schematic structure when the digital camera according to the modification 2 of embodiment of this invention is seen from the front (object side). It is BB sectional drawing of FIG.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that the same or corresponding parts in the drawings are denoted by the same reference numerals and description thereof will not be repeated.

FIG. 1 is an external perspective view of an example of an imaging apparatus according to an embodiment of the present invention.
With reference to FIG. 1, a digital camera 100 that is an imaging apparatus according to the present embodiment includes a camera body 110, a light emitting member 17, and a reflecting member 40.

  The camera body 110 has a lens barrel 30 in which the imaging lens 1 is incorporated in the front surface. The lens barrel 30 is a collapsible barrel and has a movable barrel that is doubly fitted. When the user turns on the power button 32, the movable lens barrel is extended from the camera body 110 to the photographing state position shown in FIG. When the power button 32 is turned off from this state, the movable lens barrel is embedded in the camera body 110 by the drive motor, and a so-called retracted state is obtained.

  The light emitting member 17 is disposed at the tip of the lens barrel 30. The light emitting member 17 includes a plurality of (for example, four) light emitting elements. The four light emitting elements are arranged at equal intervals at positions shifted from each other by 90 ° on the outer peripheral portion of the photographing opening at the tip of the lens barrel 30 exposed by the imaging lens 1.

  A light emitting element consists of a light emitting diode (LED: Light Emitting Diode), for example. The light emitting element is configured such that when the release button 36 is strongly pressed (fully pressed), power is supplied in synchronization with the opening operation of the shutter to emit light.

  The reflection member 40 is disposed at the tip of the lens barrel 30. The reflection member 40 is configured to reflect the return light of the light emitted from the light emitting element toward the subject at the time of so-called macro photography in which a subject close to the subject is photographed. Thereby, the light from the light emitting element can be efficiently irradiated onto the subject.

  FIG. 2 is an exploded perspective view of the tip portion of the lens barrel 30. Referring to FIG. 2, the reflecting member 40 has a circular outer shape that is substantially the same as the tip of the lens barrel 30. The reflection member 40 is formed with a transmission hole 42 having a circular outer shape that is substantially the same as the photographing opening at the tip of the lens barrel 30. The transmission hole 42 is formed so that the optical axis of the imaging lens 1 coincides with the center thereof.

  The reflection member 40 is further formed with four transmission holes 44 so that the positions of the four light emitting elements 17a to 17d coincide with each other. Each light emitting element is surrounded by the reflecting member 40 in a state where the reflecting member 40 is disposed at the tip of the lens barrel 30.

  The reflecting member 40 is made of a reflecting plate, for example. The reflecting plate can be formed of a thin plate using a metal material such as aluminum or an alloy thereof, copper or an alloy thereof, or stainless steel. Or you may form with thermoplastic resins, such as thermosetting resins, such as an epoxy, and a liquid crystal polymer.

  When a metal plate is used as the reflection plate, high light reflection characteristics can be imparted by subjecting the metal background as it is or by performing a surface treatment such as polishing.

  Further, the reflecting member 40 may be a reflecting film. The reflective film can be formed by applying a reflective paint to the tip of the lens barrel 30. As the reflective paint constituting the reflective film, acrylic urethane paint, acrylic paint, acrylic silicon paint, epoxy paint, polyester paint, and the like can be applied.

  Here, it is desirable that the reflection plate and the reflection film as the reflection member 40 have a scattering reflection surface on at least a part of the surface in order to diffuse the reflected light of the incident light. By diffusing the light incident on the scattering reflection surface, it is possible to suppress the light from being concentrated on a part of the subject and to irradiate the entire subject evenly. In addition, a scattering reflection surface can be formed by performing the process for forming many fine uneven | corrugated shapes, for example on the surface of a reflecting plate.

  In the example of FIG. 2, the reflection member 40 has a circular outer shape that is substantially the same as the tip of the lens barrel 30, but a rectangular outer shape having an aspect ratio equivalent to that of the imaging surface of the CCD 3. You may make it have. In this case, the amount of light incident on the CCD 3 can be made uniform within the imaging surface.

  When a reflecting plate is employed as the reflecting member 40, the reflecting plate can be fixed to the lens barrel 30 in a detachable manner. By attaching and detaching the reflector according to the brightness of the subject, the amount of light applied to the subject can be easily adjusted.

  Returning to FIG. 1, in addition to the lens barrel 30, a strobe light emission window 38 is provided on the front surface of the camera body 110. On the upper surface of the camera body 110, a power button 32, a mode dial 34, and a release button 36 are provided. Further, on the bottom surface, a memory card slot to which the external memory card 15 (FIG. 3) is detachably mounted and a lid (not shown) that covers the USB connector are provided.

  When the mode dial 34 is rotated, a still image shooting mode for shooting still images, a moving image shooting mode for shooting movies, a playback mode for displaying the shot images on the display 13 (FIG. 4), and various settings are set. The setting mode to be performed is switched. In the setting mode, a mode in which strobe light is emitted from the strobe light emission window 38 toward the subject and a mode in which light is emitted from the light emitting member 17 toward the subject can be switched.

  The release button 36 is a two-stage push switch. When the release button 36 is lightly pressed (half-pressed) after the framing of the subject, various shooting preparation processes such as determination of exposure conditions and automatic focus adjustment are performed. In this state, when the release button 36 is pressed once more (fully pressed), shooting is performed under the determined exposure condition and the adjusted focal length.

FIG. 3 is a block diagram illustrating the internal configuration of the digital camera 100 of FIG.
Referring to FIG. 3, a digital camera 100 includes an imaging lens 1, a diaphragm mechanism 2, an imaging device (CCD: Charge Coupled Device) 3, a CDS / AGC circuit 4, an A / D converter 5, and a signal. Processing unit 6, SDRAM 7, image processing unit 8, image compression / expansion processing unit 9, zoom processing unit 10, D / A converter 11, video encoder 12, display unit 13, and card control unit 14, a strobe device 16, a light emitting member drive unit 18, a CPU 20, an operation unit 21, a motor drive unit 22, and a CCD drive unit 23.

  The imaging lens 1 includes a main lens 1a, a zoom lens 1b, and a focus lens 1c. A diaphragm mechanism 2 is disposed behind the imaging lens 1. A motor is connected to each of the zoom lens 1b, the focus lens 1c, and the aperture mechanism 2. These motors are stepping motors, and their operation is controlled by drive pulses transmitted from a motor drive unit 22 connected to the CPU 20.

  A CCD 3 is arranged behind the diaphragm mechanism 2. A timing generator (not shown) controlled by the CPU 20 is connected to the CCD 3 via a CCD driving unit 23. The CCD drive unit 23 controls the accumulated charge amount and charge readout timing of each cell of the CCD 3 based on the timing signal input from the timing generator.

  In the digital camera 100 of FIG. 3, the optical image of the object scene is irradiated to the light receiving surface, that is, the imaging surface of the CCD 3 through the imaging lens 1 and the diaphragm mechanism 2. The aperture mechanism 2 adjusts the amount of light that passes through the imaging lens 1.

  The CCD 3 generates a charge corresponding to the brightness of the optical image of the object image formed on the imaging surface, that is, a Raw image signal, by photoelectric conversion. In addition to the CCD, a CMOS (Complementary Metal-Oxide Semiconductor) is used for the image sensor.

  The output signal (RGB signal) of the CCD 3 is sent to a CDS / ADC circuit 4 having a CDS circuit and an AGC circuit. The output signal of the CCD 3 input to the CDS / ADC circuit 4 is subjected to correlated double sampling processing by the CDS circuit and then gain adjusted to an optimum amplitude by the AGC circuit. The output signal of the CDS / ADC circuit 4 is converted into a digital video signal by the A / D converter 5. The digital video signal obtained by the A / D converter 5 is sent to the signal processing unit 6 and subjected to predetermined signal processing (white balance adjustment, color separation, YUV conversion, etc.), whereby image data in YUV format is obtained. Is converted to The image data generated by the signal processing unit 6 is stored in the SDRAM 7.

  Each part of the digital camera 100 is controlled by the CPU 20. An operation unit 21 is connected to the CPU 20. In addition to the power button 32, the mode dial 34 and the release button 36, the operation unit 21 displays a menu screen on the display 13 and a zoom operation button for zooming the zoom lens 1 b of the imaging lens 1 to the wide side and the tele side. Menu buttons are provided.

  In addition to the motor drive unit 22, CCD drive unit 23, signal processing unit 6 and SDRAM 7, the CPU 20 includes an image processing unit 8, an image compression / expansion processing unit 9, a zoom processing unit 10, a strobe device 16, and a light emitting member drive. The unit 18, the D / A converter 11 and the card control unit 14 are connected. A display 13 is connected to the D / A converter 11 via a video encoder 12. An external memory card 15 is connected to the card control unit 14. A light emitting member 17 is connected to the light emitting member driving unit 18.

  The strobe device 16 is controlled in operation by a strobe control circuit (not shown), and emits strobe light from the strobe light emission window 38 toward the subject.

  The light emitting member driving unit 18 performs on / off control of the four light emitting elements constituting the light emitting member 17. Specifically, when the light emitting member driving unit 18 fully presses the release button 36 to release the shutter, the light emitting elements 17a to 17d are turned on in synchronization with the opening of the shutter, and the CCD 3 can shoot a subject. When finished, the light emitting elements 17a to 17d are turned off.

  Next, a basic operation of the digital camera 100 having the above configuration will be described. First, when photographing a subject with the digital camera 100, the power button 32 is operated to turn on the digital camera 100. Then, the mode dial 34 is operated to select the still image shooting mode or the moving image shooting mode.

  In the still image shooting mode, when the release button 36 of the operation unit 21 is not pressed, image data shot at a constant interval (for example, 1/60 seconds) is written in the SDRAM 7 and then D / A converted. The analog video signal is converted by the device 11. The analog video signal is converted into an NTSC signal by the video encoder 12 and displayed on the display 13. Such a display is called a through display.

  When the release button 36 is pressed halfway during the through display, an exposure amount corresponding to the brightness of the subject is determined by an AE detection circuit (not shown), and the aperture diameter and shutter speed corresponding to the determined exposure amount. AE for controlling the diaphragm mechanism 2 and the CCD 3 is executed. Further, an AF detection circuit (not shown) calculates a focus evaluation value while moving the focus lens 1c, and AF for detecting the in-focus position is executed, and the photographing preparation process is completed.

  After shooting preparation processing is completed, when shooting is performed by fully pressing the release button 36, still image shooting is performed based on the determined exposure amount, and image data shot at that timing is written into the SDRAM 7. It is. The image data written in the SDRAM 7 is sent to the display 13 via the D / A converter 11 and the video encoder 12 and displayed, and after being encoded in the JPEG format by the image compression / decompression processing unit 9. The data is stored in the external memory card 15 by the card control unit 14.

(Macro shooting)
When performing macro photography using the digital camera 100 configured in this way, as shown in FIG. 4, the camera body 110 is brought close to the subject 200 and supported by a hand or a tripod. Next, the power button 32 is operated to turn on the digital camera 100. When the release button 36 is half-pressed in this state, the movable lens barrel that is doubly fitted to the lens barrel 30 is extended by the drive motor so as to be in the state shown in FIG. At this time, the lens motor is driven via the motor drive unit 22, and the focus lens 1c is moved to a position where the subject is in focus.

  When the release button 36 is fully pressed in the standby state as described above to release the shutter, power is supplied via the wiring 50 in synchronization with the opening of the shutter, and the light emitting element 17a as the light emitting member 17 is supplied. ˜17d emit light controlled by the light emitting member driving unit 18. When the light emitting elements 17a to 17d are caused to emit light, the mode dial 34 is operated to switch from the mode in which strobe light is emitted from the strobe light emission window 38 to the mode in which light is emitted from the light emitting member 17.

  At this time, when the light emitted from each light emitting element is irradiated onto the subject 200 as shown in FIG. 4, the reflected light enters the reflecting member 40 as return light from the subject 200. The reflection member 40 reflects this return light toward the subject 200. As a result, the subject 200 is directly irradiated with light emitted from each light emitting element as indicated by an arrow L1 in the figure, and through the reflecting member 40 as indicated by an arrow L2 in the figure. Will be indirectly irradiated. Therefore, it is possible to efficiently irradiate the subject 200 with the light emitted from each light emitting element.

  In particular, as described above, since the reflecting member 40 has a scattering reflection surface on the surface thereof, the light incident on the scattering reflection surface is diffused and applied to the subject 200. Can improve the uniformity.

  This eliminates the need to increase the number of light emitting elements constituting the light emitting member 17 in order to make the light irradiated to the subject 200 uniform, thereby simplifying the configuration of the light emitting member 17 and the light emitting member driving unit 18. In addition, power consumption in the light emitting member 17 is suppressed. Therefore, it is possible to obtain a high-quality image during macro photography while reducing the power consumption, size, and cost of the digital camera 100.

  Hereinafter, another configuration example of reflecting member 40 in the digital camera according to the embodiment of the present invention will be described. In the first and second modified examples shown below, even when the light amount of the light emitting member 17 is limited from the viewpoint of reducing power consumption, the light emission of the light emitting member 17 with a small amount of light is effectively used to achieve a good lighting effect. The structure of the reflecting member 40 to obtain is illustrated.

[Modification 1]
FIG. 5 is a diagram showing a schematic configuration when the digital camera 100A according to the first modification of the embodiment of the present invention is viewed from the front (subject side). 6 is a cross-sectional view taken along the line AA in FIG.

  The digital camera 100A in FIG. 5 differs from the digital camera 100 in FIG. 1 only in that the reflecting member 40 is changed to a reflecting member 40A.

  Referring to FIG. 5, four light emitting elements 17a to 17d are arranged at equal intervals at positions shifted by 90 ° from each other at the outer peripheral portion of the photographing opening at the distal end portion of the lens barrel 30 exposed by the imaging lens 1. Has been.

  The reflecting member 40 </ b> A is disposed at the tip of the lens barrel 30. The reflecting member 40 </ b> A has a circular outer shape that is substantially the same as the distal end portion of the lens barrel 30, and a transmission hole that has a circular outer shape that is substantially the same as the photographing opening at the distal end portion of the lens barrel 30.

  With reference to FIG. 6, the reflecting member 40 </ b> A further has an inclined reflecting surface inclined outward from the optical axis of the imaging lens 1.

  When macro photography is performed using the digital camera 100A configured as described above, when a release button (not shown) is fully pressed, power is supplied via the wiring 50 in synchronization with the opening of the shutter. The light emitting elements 17a to 17d emit light.

  At this time, when light emitted from each light emitting element is irradiated toward the subject 200, the reflected light is incident on the reflecting member 40 </ b> A as return light from the subject 200. In the reflecting member 40A, the return light is reflected by the inclined reflecting surface and directed again to the subject 200. For example, as indicated by an arrow L2 in FIG. 6, among the light emitted from each light emitting element, the light directed toward the outer peripheral side of the lens barrel 30 is reflected by the inclined reflection surface as the reflected light is reflected from the subject. Directed to 200. In this way, the light emitted from each light emitting element is directly applied to the subject 200 (corresponding to the arrow L1 in the drawing) and indirectly through the reflecting member 40A (the arrow in the drawing). Equivalent to L2). Therefore, it is possible to efficiently irradiate the subject 200 with light from each light emitting element.

  As a result, it is not necessary to increase the number of light emitting elements constituting the light emitting member 17 in order to make the light irradiated to the subject 200 uniform, and thus the configurations of the light emitting member 17 and the light emitting member driving unit 18 are simplified. In addition, power consumption in the light emitting member 17 is suppressed. Therefore, it is possible to obtain a high-quality image at the time of macro shooting while reducing the power consumption, size, and cost of the digital camera 100A.

[Modification 2]
FIG. 7 is a diagram showing a schematic configuration when the digital camera 100B according to the second modification of the embodiment of the present invention is viewed from the front (subject side). 8 is a cross-sectional view taken along the line BB in FIG.

  The digital camera 100B in FIG. 7 is different from the digital camera 100 in FIG. 1 in that the number of light emitting elements constituting the light emitting member 17 is changed from four to three, and the reflecting member 40 is changed to the reflecting member 40B. It differs only in respect.

  Referring to FIG. 7, three light emitting elements 17 a to 17 c are arranged at equal intervals at positions shifted from each other by 120 ° on the outer peripheral portion of the photographing opening at the tip of the lens barrel 30 exposed by the imaging lens 1. Has been.

  The reflecting member 40 </ b> B is disposed at the tip of the lens barrel 30. The reflection member 40 </ b> B has a circular outer shape that is substantially the same as the distal end portion of the lens barrel 30 and a transmission hole that has a circular outer shape that is substantially the same as the imaging opening at the distal end portion of the lens barrel 30.

  As shown in FIG. 7, by reducing the number of light emitting elements from four to three, the illumination luminance varies between the irradiation range of each light emitting element (areas 50a to 50c in the figure) and other areas. Will occur.

  In the digital camera 100B according to the second modification, the reflection member 40B reflects the return light toward a relatively low region in order to eliminate the variation in illumination luminance due to the decrease in the number of light emitting elements. In addition, an inclined reflecting surface is provided on the reflecting member 40B. As an example, as shown in FIG. 8, the reflection member 40 </ b> B has an inclined reflection surface that is inclined outward from the optical axis of the imaging lens 1.

  When performing macro photography using the digital camera 100B configured in this manner, when a release button (not shown) is fully pressed, power is supplied via the wiring 50 in synchronization with the opening of the shutter. The light emitting elements 17a to 17c emit light.

  At this time, when the light emitted from each light emitting element is applied to the subject 200 as shown in FIG. 8, the reflected light enters the reflecting member 40 </ b> A as return light from the subject 200. In the reflecting member 40A, the return light is reflected by the inclined reflecting surface and directed toward the subject 200. For example, as indicated by an arrow L2 in FIG. 8, the light emitted from each light emitting element toward the outer periphery of the lens barrel 30 is reflected by the reflected light reflected by the inclined reflecting surface. The light emitted from the element 17b is directed to a region where light is not distributed. As a result, the light emitted from each light emitting element can be efficiently and evenly applied to the subject 200.

  Therefore, according to the digital camera 100B according to the second modification, the light irradiated to the subject 200 can be made uniform without increasing the number of light emitting elements, and thus the configurations of the light emitting member 17 and the light emitting member driving unit 18 are simplified. In addition, power consumption in the light emitting member 17 is suppressed. As a result, a high-quality image can be obtained during macro shooting while reducing the power consumption, size, and cost of the digital camera 100B.

  In the above-described embodiment, the light emitting diode is exemplified as the light emitting member. However, the light emitting member is provided at the tip portion of the lens barrel and can generate other necessary light emission amounts. The light emitting element may be used. In addition, the number of light emitting diodes arranged in the lens barrel is not limited to a plurality, and even if it is one, the effects of the present invention can be enjoyed.

  Further, in the above-described embodiment, a camera having a retractable imaging lens has been described as an example. However, the present invention can also be applied to a camera having a vertically bent imaging lens in which a lens barrel moves inside the camera. It is.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is shown not by the above description of the embodiments but by the scope of claims for patent, and is intended to include meanings equivalent to the scope of claims for patent and all modifications within the scope.
