Description: TECHNICAL FIELD [0001] The present invention relates to a photographic apparatus provided with an electronic camera and a film camera. BACKGROUND OF THE INVENTION In recent years, in addition to cameras using silver halide (silver salt) films, electronic cameras using image sensors called solid-state imaging devices have been developed. This type of electronic camera uses MOS or CCD (Charge Coupler) as an image sensor.
d Device), etc., and the image formed on the imaging device such as a MOS or CCD is stored in a magnetic disk or a semiconductor memory, and the content of the storage device is reproduced by a display device or a printer. I have. However, the total number of pixels in one screen of an electronic camera is currently 400,000 pixels, but there is a problem that the sharpness is inferior to that of a photograph using a silver halide film camera. . On the other hand, in the case of a silver halide film camera, as described above, a high-quality image can be obtained. However, handling is troublesome because of the photosensitivity, and the cost is high because it is a consumable. In addition, after photographing, there is a problem that the photographed contents cannot be confirmed without developing and printing on photographic paper. Therefore, if a photograph that failed to be photographed is printed, the cost is further increased, and at least unless the image is developed, the degree of copying is not known. There was a problem that the same subject had to be taken several times under different conditions. As a method for solving the above-described problem, it is conceivable to provide an electronic camera and a film camera, and a composite camera having both functions.However, the optical system of the electronic camera and the optical system of the film camera are separately provided. If provided, there are problems such as an increase in cost and an increase in the size of the device. Further, when one optical system is shared by an electronic camera and a film camera, the light from the optical system must be separated into a solid-state image sensor and a photosensitive film, so that a photograph becomes dark. There is. This problem is particularly serious when taking a picture in a dark place such as at night or indoors. [Purpose of the Invention] The present invention has been made in view of the above-described circumstances, and a purpose thereof is to enable a simple configuration to immediately and accurately confirm photographed contents even in a dark place after photographing. Further, it is an object of the present invention to provide a photographic device capable of taking a clear film photograph. SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, according to the present invention, when a shutter switch is pressed, the electronic camera and the film are imprinted with a slightly shifted timing.

The internal structure of this camera is such that light from a subject is reflected by a reflecting mirror 16 installed at an angle of 45 ° through the photographing lens 2 along the optical path L, passes through a pentaprism 17 to a finder 11. In addition to this, the reflection mirror 16 automatically pops up in conjunction with the opening operation of the shutter curtain 18 and is sent to a silver halide film (photosensitive film) 19 to form a single-lens reflex structure. Further, a flexible circuit board 20 is formed on the back cover 13, and on this circuit board 20, a liquid crystal display device 14 is electrically connected via an interconnector 21, and the keyboard 15 is electrically connected.

In this embodiment, a CCD is used as an image sensor,
A large number of CDs are arranged in a matrix, for example, the total number of pixels is 40
The resolving power is increased by configuring the pixel to be 10,000 pixels. Then, an image of a subject corresponding to one screen is imprinted on the image sensor 26, and by detecting the distribution of shading of the subject image, the image formed thereon is converted into an electric signal. Note that as a process for extracting a signal from the image sensor 26, a frame transfer type or an interline type is known as a CCD sensor, but any one of them may be employed. Then
The image sensor 26 is formed on a film wiring board 27, and a semiconductor chip 28 constituting an LSI (large-scale integrated circuit) is mounted on the film wiring board 27. The sensor 26 and the semiconductor chip 28 are electrically connected. FIG. 1 shows a block circuit diagram of this camera, which has a one-chip microcomputer as its core. In the figure, reference numeral 31 denotes a control unit for controlling various operations. A signal corresponding to the operation of the shutter switch 6, the shutter speed dial 8, the film sensitivity dial 10, and the strobe ON / OFF switch 32 is input. Control signal a ₀ ,
b ₀ , c ₀ , d ₀ , and e ₀ are output. Here, the control signal e ₀ is an ON / OFF designation signal given to each of the strobe drive circuits 33 and 34, and is output according to the operation state of the strobe ON / OFF switch 32. The strobe drive circuits 33 and 34 start the corresponding electronic camera strobe 35 and film camera strobe 36. As described above, the photographic device of this embodiment is provided with the electronic camera strobe device and the film camera strobe device, and each of the strobe devices has the same configuration. An appropriate exposure is provided. The control signal a ₀ is sent to the optical system control mechanism 37 to drive the aperture mechanism to open the aperture by a predetermined amount. The control signal b ₀ is supplied to the electronic camera control circuit 38 as an electronic camera drive signal, and is also supplied to the electronic camera strobe drive circuit 33 as an operation command signal. In this case, the control circuit 38 includes the photographing lens 2 and the reflection mirror.
16, data corresponding to the subject image received by the image sensor 26 through the focus lens 25 and the like are sequentially read as image data for one screen, written into the semiconductor memory 39 as an image recording medium, and the display control unit 40 is read. The display is made to be displayed on the liquid crystal display device 14 through the LCD. Semiconductor memory 34
Is composed of RAM (random access memory),
For example, the image data for 36 screens can be stored, and the writing and reading operations are executed under the control of the control circuit 38. The control circuit 38 is supplied with a key input signal output from a key input unit 41 corresponding to an operation key on the keyboard 15, and the control circuit 38 responds to this by inputting a key input signal.
Display operation, writing to the semiconductor memory 39,
Controls the read operation. Further, a signal f ₀ is output from the control circuit 38, and the signal f ₀ is applied to the control unit 38 to sequentially output the control signals c ₀ and d ₀ from the control unit 31. This signal c ₀ is sent to the mirror control unit 42 and controls the flip-up operation of the reflection mirror 16. The signal d ₀ is sent to the shutter control unit 43 and controls the opening operation of the shutter curtain 18. Operation of Embodiment Now, in order to perform nighttime shooting or dark indoor shooting, first, the strobe ON / OFF switch 32 is operated to set the strobe ON. The signal e ₀ is output from the control unit 31 by this flash ON setting, and is sent to each of the flash drive circuits 33 and 34 to make them drivable. In this state, when the photographing lens 2 is pointed at the subject at the time of photographing, the subject image is captured by the photographing lens 2, the reflection mirror 16, the pentaprism 1
7. Since an image is formed on the finder 11 through the spectral prism 23, the user manually operates the distance ring 3 and the aperture ring 4 and then presses the shutter switch 6. Then, the operation signal is sent to the control circuit 31, and the control unit 31
First, the signal a ₀ is output and the optical system control mechanism 37
And the aperture is opened by a predetermined amount. Next, the signal b ₀ is output from the control section 31 in conjunction with the operation of the shutter switch 6 and is supplied to the electronic camera control circuit 38 and to the electronic camera strobe drive circuit 33. As a result, the electronic camera strobe 35 emits light, and at the same time, the light dispersed by the spectral prism 23 is sent to the image sensor 26 through the focusing lens 25.
Is a semiconductor memory that sequentially reads image data for one screen corresponding to the subject image received by the image sensor 26;
At the same time as sending to 39, it sends to the display control unit 40. Therefore, the image data for one screen read from the image sensor 26 is written to the semiconductor memory 39 and the display control unit 40
After being converted into a display drive signal by the, it is displayed on the liquid crystal display device 14. When reading of the image data for one screen is completed in this manner, the signal f ₀ is output from the control circuit 38 and sent to the control unit 31. As a result, the signal c _{0 is} output from the control unit 31.
Is output, the mirror control unit 42 flips up the reflection mirror 16, and subsequently, a signal d ₀ is output from the control unit 31, and the shutter control unit 43 opens the shutter curtain 18. The signal d ₀ output from the control unit 31 when the shutter curtain 18 is opened.
Is also sent to the film camera strobe drive circuit 34, so that the film camera strobe 36
Emits light. For this reason, the subject image from the photographing lens 2 is sent to the photosensitive film 19 when the shutter curtain 18 is opened, and is captured. Thus, when the shutter is pressed during shooting,
The subject image is projected onto the image sensor 26 with the emission of the electronic camera strobe 35 and recorded in the semiconductor memory 39, and is then projected onto the photosensitive film 19 with the emission of the film camera strobe 36. That is, when the shutter is pressed, imprinting by the electronic camera and imprinting by the film camera are performed at staggered timings, and the respective strobes are fired at the imprinting timing.
The same subject can be photographed almost simultaneously with an electronic camera and a film camera, and even at night, stroboscopic photographing can be performed, and clear electronic and film photographs can be taken. Since the above operation is repeated every time the shutter is pressed, the image data for 36 screens is sequentially recorded in the semiconductor memory 39 in the order in which the image data was taken. Since the photographed contents are displayed on the liquid crystal display device 14, it is possible to confirm whether or not the photographed object has been successfully photographed by looking at the display. The subject can be taken again. Also, 36
Before or after the photographing of the screen has been completed, when confirming the already photographed contents, the ten-key K1 on the keyboard 15 is used to confirm the image number, for example, if the tenth image is to be confirmed, the image number is set to `` 10 ”And press the display key K2
Operate. As a result, the address of the semiconductor memory 34 is specified, and the tenth image data is read out and displayed on the liquid crystal display device 14. Here, in order to check the next eleventh image, if the plus key K3 is operated once, the eleventh image data is read out from the semiconductor memory 39 and displayed. , The twelfth image data is read and displayed. Thus, each time the plus key K3 is operated, the next image can be sequentially displayed. On the other hand,
For example, if the minus key K4 is operated once in the state where the tenth image is displayed, the ninth image data is read out from the semiconductor memory 39 and displayed.
After the first operation, the eighth image data is read out and displayed. Thus, each time the minus key K4 is operated, the previous image can be sequentially displayed. In the above embodiment, the electronic camera strobe 35 was used.
And a strobe 36 for a film camera, but two capacitors are provided for a single light-emitting part (discharge tube), and a charging circuit for the two capacitors is formed simultaneously with turning on the strobe ON / OFF switch. Then, one capacitor can be discharged at the time of imprinting of the electronic camera, and the other capacitor can be discharged at the time of imprinting of the film camera to instantaneously emit a single light emitting portion twice. . In the above embodiment, the CCD is used as the image sensor of the solid-state imaging device.
May be a combination of CPD and the like. In addition to a semiconductor memory as a recording medium of the electronic camera, a magnetic disk and a magnetic bubble memory as a nonvolatile solid-state memory may be used. In addition, the electronic camera may be a color camera. In this case, for example, this can be realized by disposing a color filter called a mosaic filter in which three primary colors are scattered in a mosaic form immediately before the image sensor. [Effects of the Invention] As described in detail above, when the shutter switch is pressed, the electronic camera and the film are imprinted at slightly different timings, and the strobes are respectively imprinted. Since the light is emitted at the timing, it is possible to confirm the shooting content immediately and accurately after shooting even in a dark place with a simple configuration,
Moreover, there is an effect that a clear film photograph can be taken.
