  A rear monitor 10 made of a TFT (Thin Film Transistor) liquid crystal panel is provided on the rear side of the digital camera 1, and a finder 11 for observing a subject image is provided above the rear monitor 10. An eyepiece lens 13 is provided inside the viewfinder 11, and a pentaprism 14 is provided behind the eyepiece lens 13. Below the pentaprism 14 is provided an in-finder display device 12 composed of a self-luminous organic EL (Electro Luminescence) panel having translucency. When the subject light reflected by the first mirror 5 passes through the in-finder display device 12, the photographing information displayed on the in-finder display device 12 is superimposed, and the subject image is observed together with the photographing information in the finder 11. The in-finder display device 12 constitutes a display unit that superimposes photographing information on a subject image incident through the photographing lens 2.

  A projector mirror 15 is provided above the eyepiece lens 13 and the pentaprism 14 with the right end portion thereof being pivotally supported. A projector light source 17 is provided above the reflection surface of the projector mirror 15 via a lens 16. Around the upper half of the projector light source 17, there is provided a reflector 18 for reflecting the light emitted from the projector light source 17 downward. When the projector mirror 15 is at the illustrated observation position, the subject image on which the photographing information is superimposed by the in-viewfinder display device 12 is guided to the eyepiece lens 13 by the pentaprism 14 as shown in FIG. The image is formed and observed in the finder 11. On the other hand, when the projector mirror 15 is at the projection position shown in FIG. 2 with the left end rotated downward about the support shaft at the right end, the light emitted from the projector light source 17 is reflected by the projector mirror 15. The reproduced image guided to the in-finder display device 12 and displayed on the in-finder display device 12 is reflected by the first mirror 5 and projected onto the screen 35 in front of the digital camera 1 by the photographing lens 2. 2 that are the same as or correspond to those in FIG. 1 are assigned the same reference numerals, and descriptions thereof are omitted.

  The photographing lens 2 has optical elements such as a focal length longer than the eyepiece lens 13 and an effective lens diameter larger than that of the eyepiece lens 13. The photographing lens 2 is on the side opposite to the side on which the eyepiece 13 of the in-viewfinder display device 12 is provided, and the projection performance is higher than that of the eyepiece. The projector light source 17 constitutes a light source provided on the side where the eyepiece 13 of the in-viewfinder display device 12 is provided, and the projector mirror 15 and the pentaprism 14 transmit light emitted from the projector light source 17. Light guide means for guiding to the in-viewfinder display device 12 is configured. Further, the photographing lens 2 and the first mirror 5 are illuminated by the light guided by the light guide means, and the in-finder display device 12 is illuminated from the side of the in-finder display device 12 where the eyepiece 13 is provided, so that the in-finder display is performed. Projecting means for projecting a reproduced image projected on the side opposite to the side on which the eyepiece 13 of the apparatus 12 is provided to the subject side is configured.

  FIG. 3 is a block diagram showing an outline of an electric circuit configuration of the digital camera 1 shown in FIG.

  The digital camera 1 includes a CPU (Central Processing Unit) 21. A non-volatile memory and a buffer memory (not shown) are connected to the CPU 21, and a control program and the like that are referred to when the CPU 21 performs various controls are stored in the non-volatile memory. In accordance with a control program stored in the nonvolatile memory, the CPU 21 controls each part of the circuit using the buffer memory as a temporary storage work area, and operates various device functions of the digital camera 1.

  The subject light taken into the digital camera 1 through the photographing lens 2 forms an image on the imaging surface 8 a of the imaging device 8. The image sensor driving circuit 22 drives the image sensor 8 based on a control signal from the CPU 21, whereby the subject image formed on the imaging surface 8 a of the image sensor 8 is converted into an analog image signal, and AFE (Analog Front End) circuit 23. The imaging signal is subjected to predetermined analog processing in the AFE circuit 23 and converted into a digital signal in an A / D (Analog / Digital) converter 24. An ASIC (Application Specific Integrated Circuit) 25 constitutes an image processing circuit. The imaging signal converted into a digital signal by the A / D converter 24 is input, and white balance processing or gamma is applied to the imaging signal. Image processing such as correction is performed, and image data of the captured image is generated. The image data generated by the ASIC 25 is subjected to compression processing by the CPU 21, temporarily stored in the buffer memory, and recorded in a memory card (not shown) that is detachable from the digital camera 1.

  Based on the control signal from the CPU 21, the image display circuit 26 displays the currently set shooting information such as the shutter speed and exposure value on the in-finder display device 12 and is imaged on the imaging surface 8 a of the imaging element 8. The captured image or the like is displayed on the rear monitor 10 as a through image. In the present embodiment, an image selected by a user from images recorded on a memory card or the like is reproduced and displayed on the in-finder display device 12 by the image display circuit 26. The CPU 21 and the image display circuit 26 constitute display switching control means for displaying a desired recorded reproduced image on the in-finder display device 12 in place of shooting information.

  Also connected to the CPU 21 are an operation mode SW (switch) 11 for switching the operation mode of the digital camera 1, an AF-SW 28 for detecting a half-press operation of the shutter button, and a release SW 29 for detecting a full-press operation of the shutter button. ing. When the operation mode SW 27 is switched, the operation mode of the digital camera 1 is a camera mode in which the subject is photographed with the finder 11 and a live view mode in which the subject is photographed with the rear monitor 10. Alternatively, the operation mode is switched to any one of the projector modes in which the captured image is projected onto the external screen 35 and the captured image is reproduced and displayed. Further, the focal length of the taking lens 2 is automatically adjusted by operating the AF-SW 28. Further, when the release SW 29 is operated, a subject image incident from the photographing lens 2 is photographed.

  In addition, the above-described AF module 9 is connected to the CPU 21 through the AF circuit 30, and the above-described AF motor 4 is connected through the AF lens driving circuit 31.

  When the operation of the AF-SW 28 is detected, the AF circuit 30 causes the AF module 9 to separate the subject light reflected by the second mirror 6 and incident on the separator lens and form an image on the AF sensor. The interval between the two imaged subject images is measured. The AF lens driving circuit 31 drives the above-described AF motor 4 so that the measured interval becomes constant, and the AF lens driving circuit 31 performs AF at the in-focus position where the subject image focused on the imaging surface 8a of the imaging element 8 is in focus. The lens 3 is moved, and the focal length of the taking lens 2 is automatically adjusted by the phase difference detection method. The CPU 21, the AF circuit 30, the AF module 9, the AF lens driving circuit 31, and the AF lens 3 constitute a focal length adjusting unit that adjusts the focal length of the photographing lens 2.

  Further, a shutter drive circuit 33 is connected to the CPU 21. The shutter drive circuit 33 performs control to open the shutter 7 when the operation of the release SW 29 is detected. When the shutter 7 is opened for a predetermined time under the control of the shutter drive circuit 33, the subject image is exposed to the imaging surface 8a of the imaging device 8 for a predetermined time, and shooting is performed.

  Further, a mirror drive circuit 32 and a light source drive circuit 34 are connected to the CPU 21. The mirror drive circuit 32 drives each mirror 5, 6, 15 based on a control signal from the CPU 21. The first mirror 5 and the second mirror 6 are mirror-downed by the mirror driving circuit 32 as shown in FIG. 1B in the camera mode shown in FIG. 1A and the projector mode shown in FIG. In the live view mode shown, the mirror is raised as shown in FIG. In addition, the projector mirror 15 is moved up to the observation position by the mirror driving circuit 32 as shown in FIG. 1A in the camera mode shown in FIG. 1A and moved to the observation position. In the projector mode shown in FIG. The mirror is moved down to move to the projection position. The light source drive circuit 34 controls the projector light source 17 to emit light when the projector mirror 15 moves to the projection position in the projector mode. The light emitted from the projector light source 17 is guided to the in-finder display device 12 by the projector mirror 15 and the pentaprism 14, and illuminates the in-finder display device 12 from the eyepiece 13 side. For this reason, the reproduced image displayed on the in-finder display device 12 is projected on the photographing lens 2 side of the in-finder display device 12 by this illumination, reflected by the first mirror 5 and reflected by the photographing lens 2 as shown in FIG. Is projected onto the screen 35.

  The mirror drive circuit 32 supplies the observation position shown in FIG. 1A for guiding the subject image on which the photographing information is superimposed by the in-finder display device 12 to the finder 11 and the light emitted from the projector light source 17 to the in-finder display device 12. Driving means for driving the projector mirror 15 is configured at the projection position shown in FIG. 2 where the reproduction image that is guided and displayed on the in-finder display device 12 is projected by the photographing lens 2. Further, the focus adjustment of the subject image projected on the screen 35 is performed in advance by displaying a predetermined pattern image as shown in FIG. 4 on the screen 35, and the focus of the photographic lens 2 on the projected pattern image under the control of the CPU 21. The position of the AF lens 3 is adjusted by the above-described focal length adjusting means so that the distance is matched. The CPU 21 causes the focal length adjustment means to adjust the focus of the projected image on the screen 35 using a predetermined pattern image displayed on the in-finder display device 12 by the display control means and projected onto the screen 35 by the photographing lens 2. Consists of focus adjustment means.

  FIG. 5 is a flowchart showing an outline of the photographing process and the projection process performed by the CPU 21.

  When the CPU 21 detects that the power switch is turned on (ON) in FIG. 5 and S1 and power is supplied to each part of the circuit, and the operation mode SW27 is operated in S2, the operation mode is set to the camera mode in S3. It is determined whether or not it has been switched to. If the camera mode has been switched and this determination is “YES”, the CPU 21 sets the operation state of the in-finder display device 12 to “ON” in S 4 and displays the shooting information currently set in the digital camera 1. The image is displayed on the in-finder display device 12. In this state, when subject light is incident from the photographing lens 2, the finder 11 observes a subject image on which photographing information is superimposed. Next, in S5, the CPU 21 determines whether or not the AF-SW 28 is “ON”. If this determination is “NO”, the process of S5 is repeated. When the AF-SW 28 is turned “ON” and the determination in S5 is “YES”, the CPU 21 performs photometry / AF processing in S6. In this photometry / AF processing, the CPU 21 detects the phase difference of the subject image by the AF circuit 30 based on the photometry result of the AF module 9, and drives the AF motor 4 to the AF lens drive circuit 31 according to the detection result. Then, the AF lens 3 is moved to the in-focus position where the subject image is in focus.

  Next, in S7, the CPU 21 determines whether or not the release SW 29 is “ON”. If this determination is “NO”, the process returns to S5 and the above-described process is repeated. When the release SW 29 is “ON” and the determination in S7 is “YES”, the CPU 21 causes the first mirror 5 and the second mirror 6 to jump up from the state shown in FIG. 1A in S8. An up process is performed to guide the subject light incident from the photographing lens 2 to the image sensor 8. Subsequently, in S9, the CPU 21 performs an aperture driving process for controlling the aperture amount of the aperture, and adjusts the amount of subject light incident from the photographing lens 2 so as to obtain an appropriate exposure. Subsequently, the CPU 21 performs a photographing process in S10. In this photographing process, the subject image exposed to the imaging surface 8a of the image sensor 8 by the shutter 7 for a predetermined time is subjected to photoelectric conversion, predetermined image processing is performed to generate image data, and the generated image data is recorded on a memory card. To do. Next, in S11, the CPU 21 performs a process of returning the mirrors 5 and 6 mirrored up in S8 to the original mirror-down position shown in FIG. 1A, and ends the photographing process.

  If the operation mode is not switched to the camera mode in S3 and the determination in S3 is “NO”, the CPU 21 determines in S12 whether or not the operation mode is switched to the live view mode by the operation mode SW27. Is determined. When the live view mode has been switched and this determination is “YES”, the CPU 21 raises the first mirror 5 and the second mirror 6 to the positions shown in FIG. Process. Subsequently, in S <b> 14, the CPU 21 performs a process of opening the shutter 7 so that subject light incident through the photographing lens 2 passes through the shutter 7 and reaches the imaging surface 8 a of the imaging device 8. Next, in S <b> 15, the CPU 21 performs a process of displaying the subject image captured on the imaging surface 8 a of the imaging element 8 on the rear monitor 10 as a through image. In the live view mode, the subject light captured in the digital camera 1 via the photographing lens 2 does not reach the finder 11 by the processing of S13, so that the subject image cannot be observed from the finder 11, but By the process of S15, it is possible to compose the subject on the rear monitor 10.

  Next, in S <b> 16, the CPU 21 determines whether or not the AF-SW 28 is “ON”. If this determination process is “NO”, the process returns to S13 and the above-described process is repeated. On the other hand, when the AF-SW 28 is “ON” and the determination in S16 is “YES”, the CPU 21 performs photometry / AF processing in S17. In the live view mode, the first mirror 5 and the second mirror 6 are mirrored up in the process of S13, and the subject light does not reach the AF module 9. Therefore, the photometry / AF process in S17 is performed in S6. Unlike the processing, it is performed by a contrast detection method using a subject image formed on the imaging surface 8a of the imaging element 8. The AF motor 4 is driven by the AF lens driving circuit 31 by the photometry / AF processing by the contrast detection method, and the AF lens 3 is moved to the in-focus position where the subject image is in focus.

  Next, in S18, the CPU 21 determines whether or not the release SW 29 is “ON”. If this determination is “NO”, the process returns to S13 and the above-described process is repeated. When the release SW 29 is “ON” and the determination in S18 is “YES”, the CPU 21 performs the aperture driving process in S19 as in S9. Subsequently, the CPU 21 performs a photographing process in S20 as in S10. Thereafter, in S21, the CPU 21 performs mirror down processing for returning the first mirror 5 and the second mirror 6 mirrored in S13 from the positions shown in FIG. 1B to the original positions shown in FIG. To finish the shooting process.

  If the operation mode is switched to the projector mode in S12 and the determination in S12 is “NO”, the CPU 21 moves the projector mirror 15 to the projection position shown in FIG. 2 in S22. I do. Subsequently, the CPU 21 turns on the operation state of the in-finder display device 12 in S23, and turns on the projector light source 17 to start lighting the projector light source 17 in S24. The light emitted from the projector light source 17 is collimated by the lens 16 together with the light reflected downward by the reflecting plate 18 and is guided to the projector mirror 15 and the pentaprism 14 so that the in-finder display device 12 is connected to the eyepiece 13 side. Illuminate from.

  Next, in S25, the CPU 21 determines whether or not the AF-SW 28 is “ON”. When this determination is “YES”, the CPU 21 displays the pattern image formed of the black and white stripe patterns shown in FIG. 4 on the in-finder display device 12 in S26, and the white projection surface of the screen 35 is displayed. A pattern projection process is performed to project the pattern. In this pattern projection processing, a pattern image displayed on the in-finder display device 12 is projected on the photographing lens 2 side of the in-finder display device 12 by light from the projector light source 17, reflected by the first mirror 5 and reflected by the photographing lens 2. By enlarging, the pattern image is greatly projected on the screen 35.

  Next, the CPU 21 performs AF processing in S27. In this AF process, the CPU 21 reflects light from the pattern image projected on the screen 35 to the AF module 9 by the second mirror 6 as shown in FIG. The circuit 30 detects the phase difference of the pattern image. Based on the detection result, the CPU 21 controls the AF lens driving circuit 31 to drive the AF motor 4 to move the AF lens 3 to a focus position where the pattern image projected on the screen 35 is in focus.

  When the AF-SW 28 is not “ON” and the determination in S25 is “NO”, or when the processing in S27 is completed, the CPU 21 selects the user from the images recorded on the memory card or the like in S28. An image projection process is performed in which the image selected by the above item is reproduced and displayed on the in-finder display device 12 and a desired reproduced image is projected onto the screen 35. Next, in S29, the CPU 21 determines whether or not an operation for ending the projector mode has been performed by a switching operation of the operation mode SW27 or the like. If this determination is “NO”, the processing returns to S25 and the above-described processing is repeated. On the other hand, if the determination in S29 is “YES”, the CPU 21 performs an image display end process in S30. In this process, the CPU 21 returns the projector mirror 15 moved to the projection position shown in FIG. 2 in S22 to the observation position shown in FIG. The projection of the reproduced image on 35 is terminated. When the process of S30 ends, the CPU 21 ends the projection process.

  According to the digital camera 1 according to the present embodiment, as described above, the subject image on which the photographing information is superimposed by the in-finder display device 12 is observed in the finder 11 by the processing in FIGS. Further, in the process of S28, the in-finder display device 12 is illuminated by the light guided from the projector light source 17 to the in-finder display device 12 by the projector mirror 15 and the pentaprism 14, and the desired image displayed on the in-finder display device 12 is displayed. Is displayed on the side opposite to the side on which the eyepiece lens 13 of the in-viewfinder display device 12 is provided, and is projected onto the screen 35 provided on the subject side by the photographing lens 2. In the present embodiment, the photographing lens 2 has optical elements such as a focal length longer than that of the eyepiece lens 13 and an effective lens diameter larger than that of the eyepiece lens, so that the projection performance is higher than that of the eyepiece lens 13. Therefore, the reproduced image projected on the screen 35 can be clearly projected by enlarging it at a higher magnification than when projected by the eyepiece lens 13 as in a conventional digital camera. Therefore, a desired reproduced image can be projected onto the screen 35 to be confirmed and viewed by a large number of people.

  In addition, since the distance between the external screen 35 and the digital camera 1 is indeterminate and changes depending on the projection environment, if a reproduced image is projected on the screen 35 immediately after the processing of S24, There is a high possibility that the camera will be out of focus. However, in the present embodiment, the pattern image shown in FIG. 4 is displayed on the in-finder display device 12 by the CPU 21 in the processing of FIGS. The focal length of the photographic lens 2 is adjusted by the focal length adjustment unit based on the control of the focus adjustment unit in step S27 so that the pattern image projected on the screen 35 is in focus. Therefore, the reproduced image displayed on the in-finder display device 12 can be projected on the screen 35 in a focused state.

  In the present embodiment, when the projector mirror 15 is driven to the observation position shown in FIG. 1A by the mirror drive circuit 32, the subject image on which the photographing information is superimposed is observed from the finder 11 by the in-finder display device 12. The 5 and S22, when the projector mirror 15 is driven to the projection position shown in FIG. 2 by the mirror driving circuit 32, the in-finder display device 12 is illuminated by the light emitted from the projector light source 17, and the finder is displayed. A reproduced image displayed on the inner display device 12 is projected by the photographing lens 2. For this reason, it is possible to provide a low-cost digital camera 1 capable of clearly enlarging the reproduced image by simply providing the projector mirror 15 driven by the mirror driving circuit 32 together with the projector light source 17 in the existing digital camera. Become.

  In the above embodiment, the case where the photographing apparatus according to the present invention is applied to the single-lens reflex digital camera 1 to which the photographing lens 2 is detachable has been described. However, the photographing apparatus according to the present invention has an integral photographing lens. The present invention can also be applied to a compact digital camera or a digital camera other than the single-lens reflex system capable of observing a subject image incident from the photographing lens 2 and reaching the image sensor 8 with the finder 11.

  In the above embodiment, in the projector mode, when the shutter button is pressed halfway and the AF-SW 28 is turned “ON” in the process of FIG. 5 and S25, the AF function is activated in the process of S27. The present invention is not limited to this. For example, in the projector mode, a dedicated operation member for activating the AF function of S27 is provided, and when this operation member is operated, the pattern image shown in FIG. A configuration in which the distance is adjusted is also possible.

  Moreover, although the case where the self-light-emitting organic EL panel which has translucency was used as the display apparatus 12 in a finder was demonstrated in the said embodiment, the display panel used for the display apparatus 12 in a finder has translucency, for example. A transparent liquid crystal or the like may be used, and the type can be changed as appropriate.

  In the above embodiment, the case where the subject image is displayed on the rear monitor 10 when the operation mode is switched to the live view mode has been described, but the present invention is not limited to this. For example, in the live view mode, a through image may be displayed on the in-finder display device 12 based on image data generated from an imaging signal output from the imaging device 8. In the live view mode, a through image may be displayed on either the rear monitor 10 or the in-viewfinder display device 12 but not both. According to the above configuration, the subject image can be observed in the viewfinder 11 even in the live view mode, and the photographer can check the composition of the subject by looking through the viewfinder 11 as in the camera mode. . In the above configuration, a through image is displayed on the in-finder display device 12 with the first mirror 5 and the second mirror 6 in the live view mode and the incidence of light on the in-finder display device 12 is blocked. Although displayed, since the self-luminous organic EL panel is used for the in-finder display device 12, the photographer can visually recognize the subject image with the finder 11.

  In the above embodiment, the case where the reproduced image is projected onto the screen 35 by the photographing lens 2 has been described, but the present invention is not limited to this. For example, another lens different from the photographic lens 2 having a higher projection performance than the eyepiece lens 13 is provided at an arbitrary position on the side opposite to the side where the eyepiece lens 13 of the in-viewfinder display device 12 is provided. It is also possible to adopt a configuration in which the reproduced image is projected onto the screen 35 by the lens.

  In the above embodiment, the case where the image of the striped pattern shown in FIG. 5 is projected onto the screen 35 as the predetermined pattern image in the processing of FIGS. 5 and S26 has been described, but the predetermined pattern image to be projected onto the screen 35 is It can be changed as appropriate.

  In the above embodiment, the case where the operation mode is switched by operating the operation mode SW27 has been described with reference to FIGS. However, the present invention is not limited to this. For example, it is possible to adopt a configuration in which the operation mode is switched on the menu screen displayed on the rear monitor 10. In addition, for example, a dedicated projector mode operation SW for operating the projector mode may be provided, and the operation mode may be switched to the projector mode by operating the projector mode operation SW.

  In the above embodiment, the case where the pentaprism 14 is provided in the finder has been described. However, a configuration in which a pentamirror is provided instead of the pentaprism 14 is also possible.

  In the above embodiment, the case where the photographing apparatus according to the present invention is applied to a digital camera has been described. However, various kinds of video cameras such as a video camera for photographing a moving image and a still image provided with display means for superimposing photographing information on a subject image. The present invention can also be applied to a photographing apparatus.
