Description

  The present invention relates to an imaging apparatus that performs imaging using an auxiliary light device, and more particularly to an imaging apparatus suitable for obtaining an intraoral image for dental treatment.

  Conventionally, various cameras for photographing the inside of the oral cavity have been proposed for performing dental treatment.

  As a camera for photographing the oral cavity, a ring strobe connected with a multi-stage dimming regulator and a close-up lens for close-up photography can be attached to the inside of the ring strobe. A camera that obtains a plurality of types of images at different magnifications is known (see, for example, Patent Document 1).

  Also, in order to reduce the effects of shadows and reflections during flash photography, two flash light emitting units are arranged at different positions with respect to the photographing optical axis, and each of them emits light alternately to shoot and synthesize two images. An imaging device is known that stores a single piece of image data (see, for example, Patent Document 2).

There is also known a camera in which the light emission combination of a plurality of light emitting units can be changed in advance, and a photographer sets a light emission combination and performs shooting.

  FIG. 2 is a block diagram showing a schematic configuration of the camera 1 which is the imaging apparatus according to the present embodiment. Although the camera 1 can be configured using a CCD or CMOS image sensor, the camera 1 of the present embodiment will be described using a CCD.

  The CCD area sensor 41 (hereinafter abbreviated as CCD 41) is a color area imaging sensor in which R (red) light, G (green) light, and B (blue) light transmission filters are arranged in pixel units (pixel units). The object light image formed by the lens unit 3 is converted into an image signal of each color component of R (red) light, G (green) light, and B (blue) light (a signal of a pixel signal received in each pixel unit). The signal is photoelectrically converted into a signal consisting of a column.

  The timing generator 46 generates a drive control signal for the CCD 41 based on a reference clock transmitted from a reference clock generator 79 described later. The drive control signal generated by the timing generator 46 includes, for example, an integration start / end timing signal for controlling the exposure start and end timings in the CCD 41, and a light reception signal readout control signal (horizontal synchronization signal, vertical synchronization signal). Clock signals such as a signal, a transfer signal, etc., and when these clock signals are supplied to the CCD 41, the CCD 41 performs drive control corresponding to each clock signal.

  The signal processing circuit 42 includes a CDS circuit 43 and an AGC circuit 44, and a predetermined process is performed on the image signal via these components.

  A CDS (Correlated Double Sampling) circuit 43 reduces noise generated at the time of reading from the image signal read from the CCD 41 and corrects dark noise by OB clamping operation. An AGC (automatic gain control) circuit 44 adjusts the gain of the image signal processed by the CDS circuit 43.

  The A / D converter 45 converts each pixel signal constituting the image signal input from the AGC circuit 44 into a digital signal. The A / D converter 45 converts each pixel signal of an analog signal into, for example, a 14-bit digital signal based on the A / D conversion clock input from the reference clock generation unit 79.

  In this way, the image signal read out by the CCD 41 is subjected to predetermined processing by the signal processing circuit 42 and the A / D converter 45 and converted into a digital image signal. The digitized image signal is captured by the image processing CPU 61 and subjected to predetermined processing.

  The image processing CPU 61 is composed of a microcomputer, and comprehensively controls image signal processing operations performed by the digital camera 1. In the following, processing for a digital image signal performed by the image processing CPU 61 will be described.

  First, the image signal captured by the image processing CPU 61 is written into the image memory 81 in synchronization with the reading of the image signal output from the CCD 41. That is, a digital image signal used for processing performed by the image processing CPU 261 is once recorded in the image memory 81 and taken out from the image memory 81 and used for processing in each block.

  The image processing CPU 61 includes an image processing unit 62, a white balance control unit 71, and a reference clock generation unit 79, and a predetermined process is performed on the image signal via these components. Hereinafter, a predetermined process for the image signal performed by the image processing CPU 61 will be described.

  As shown in FIG. 2, the image processing unit 62 includes, for example, a black level correction unit 63, a white balance gain calculation unit 66, a gamma correction unit 67, a matrix calculation unit 68, a shading correction unit 69, an image compression unit 70, and the like. Is done. The image processing unit 62 performs known image signal processing on the digital image signal extracted from the image memory 81. Then, the digital image signal that has undergone predetermined processing at these parts is stored in the image memory 81 again.

  In addition, the image processing CPU 61 of the camera 1 according to the present embodiment includes an evaluation unit 71 that is an evaluation unit. The evaluation unit 71 includes a histogram generation unit 73 that reads out an image stored in the image memory 81 and generates a histogram, and a whiteout determination unit 74 that determines the presence or absence of a whiteout portion from the generated histogram. .

  The display device 11 (LCD in this example) displays an image or the like. The LCD drive circuit 85 includes a buffer memory (VRAM) that temporarily stores an image signal read from the image memory 81 by the image processing CPU 61, and causes the display device 11 to display an image of the image signal as a field image.

  The camera control CPU 91 is composed of a microcomputer, and performs overall control of the photographing operation of the camera 1 by sequentially controlling driving of each member based on switch signals generated by switch operations of a switch group 95 described later.

  As described above, in the camera 1, the image processing CPU 61 performs the above-described signal processing on the image signal fetched from the CCD 41, and records the image signal subjected to these processing in the image memory 81.

  The camera 1 records the image signal captured from the CCD 41 under the mode set by the operation switch group 95 in the image memory 81 or displays it on the display device 11.

  In the shooting standby state (the state set to the “still image shooting mode”), the image signal is fetched from the CCD 41 through the signal processing circuit 42 and the A / D converter 45 from the CCD 41 at a predetermined interval such as every 1/30 seconds. It is. As described above, the captured image signal is subjected to predetermined signal processing at a portion from the black level correction unit 63 to the shading correction unit 69 of the image processing unit 62 in the image processing CPU 61, and then as a digital image signal. Recorded in the image memory 81. Then, the image signal recorded in the image memory 81 is read, and the read image signal is displayed on the display device 11 as a field image via the LCD drive circuit 85 (hereinafter referred to as a preview image display).

  At the time of image recording, the image signal is compressed by the image compression unit 70 of the image processing unit 62 in the image processing CPU 61 in order to obtain an image of the set recording resolution, and the obtained compressed image is a memory card driver 82. To the memory card 83.

  In the reproduction mode (the state set to “reproduction mode”), the image signal read from the memory card 83 is subjected to predetermined signal processing by the image processing CPU 61 and displayed on the display device 11 via the LCD drive circuit 85. To do.

  A switch group 95 in FIG. 2 is a switch group corresponding to the release button 52, the main switch button 51, the zoom button 55, the menu button 56, the selection button 57, the set button 58, and the like in FIG.

  Furthermore, in the camera 1 of the present embodiment, four flash light emitting units 12a to 12d, which are auxiliary light devices, are arranged. These flash light emitting units 12a to 12d can selectively emit light.

  In this specification, “acquisition” of an image means a state in which data recorded when the power supply of the imaging apparatus is stopped is recorded in a memory, and in this example, image data is stored in the image memory 81. Is stored. “Photographing and recording” refers to a state in which recorded data is recorded in a memory that does not disappear even when the power supply of the imaging apparatus is stopped. In this example, the image data is stored in the memory card 83. Is.

  In addition, the memory for performing “shooting and recording” is not limited to the memory card or the built-in memory built in the camera of this example, and when a system that performs an interface between the camera and the external PC is configured, the external PC It may be a storage medium such as a hard disk.

  FIG. 3 is a diagram showing an imaging state of the dentition of the person 2 who is the subject using the camera 1 according to the present embodiment.

  As shown in the figure, a close-up of the dentition of the subject 2 is obtained to obtain an intraoral image. In addition, in order to keep the positional relationship between the camera 1 and the person 2 as the subject accurate so as not to cause a deviation during the photographing of a plurality of images, the positional relationship between the camera 1 and the person 2 as the subject is fixed. It is desirable to use a fixture.

(First embodiment)
Hereinafter, an intraoral photographing operation of the camera 1 according to the first embodiment will be described.

  FIG. 4 is a flowchart showing the operation of the camera 1 according to the first embodiment in the shooting mode. A description will be given according to the flow shown in FIG.

  First, in step S101, it is confirmed whether or not the power is on. If the power is not on (step S101; No), that is, if the main switch button is operated, the process ends (step S401).

  If the power is on (step S101; Yes), a preview image is displayed (step S102). Next, it is determined whether or not the release button is depressed by one step, that is, whether or not the switch S1, which is a start instruction operation for photographing preparation operation, is turned on (step S103). If the switch S1 is not turned on (step S103; No), the process returns to step S101, and steps S101 to S103 are repeated.

  When the switch S1 is turned on (step S103; Yes), first, a shooting preparation operation is performed (step S104). The shooting preparation operation refers to focus adjustment (AF operation) for focusing on a subject and determination of exposure conditions for shooting.

  When the shooting preparation operation is completed, first, an image shot with only steady light is acquired (step S105). Next, images obtained by causing all four flash light emitting units 12a to 12d (see FIG. 1) to emit light are acquired (step S106). Next, an image captured by emitting light from the two flash light emitting units 12a and 12c across the optical axis is acquired (step S107). Further, an image captured by emitting light from the two flash light emitting units 12b and 12d across the optical axis is acquired (step S108). These steps S105 to S108 are preferably performed continuously in a short time. The four frames of image data acquired in steps S105 to S108 are temporarily recorded in the image memory 81 (see FIG. 2).

  Next, evaluation is performed using the image data temporarily recorded in the image memory 81 (step S109). This evaluation is performed by the histogram generation unit 73 and the whiteout determination unit 74 in the evaluation unit 71 which is an evaluation unit in the image processing CPU 61 of the camera 1 shown in FIG.

  More specifically, the histogram generation unit reads out the image stored in the image memory 81 and generates a histogram for each image, and the whiteout determination unit 74 determines the presence or absence of a whiteout portion from the histogram.

  FIG. 5 is an example of a histogram of acquired image brightness data. This figure shows the brightness on the horizontal axis and the appearance frequency on the vertical axis. The brightness on the horizontal axis is divided into 8 bits (0 to 255) with the darker side being 0, and The example which displayed the appearance frequency with the histogram is shown.

  For example, when the criterion of determination is that the number of data with brightness 230 or more is 1% or more of the total number of pixels, it is determined that there is a whiteout portion in the image. In this case, in the image from which the histogram shown in FIG. 5A is obtained, the number of data of 230 or more is 1% or more of the total number of pixels, and therefore it is determined that whiteout has occurred. On the other hand, in the image from which the histogram shown in FIG. 5B is obtained, since the number of data of 230 or more is not 1% or more of the total number of pixels, it is determined that whiteout has not occurred. Note that the criterion for determination is not limited to the above, and is appropriately set in advance.

  Returning to FIG. 4, based on the evaluation result of the evaluation unit 71, the combination of the flash light emitting units that emit light during the main photographing is determined (step S110). The combination of the flash light emitting units that emits light during the main photographing is the flash light emission when an image that is determined to have no whiteout by the evaluation in the evaluation unit 71 performed in step S109 is obtained. It is a combination of parts.

  The determination of the combination of the flash light emitting units based on this evaluation gives priority to the combination of the flash light emitting units that can obtain an image with no whiteout among the images subjected to the flash light emission. Only when the overexposure occurs in all the images that have been subjected to flash emission, photographing with only steady light is determined.

  Next, it is determined again whether or not the switch S1 is ON (step S111). If the switch S1 is not turned on (step S111; No), the process returns to step S103, and the four frames of image data acquired in steps S105 to S108 are deleted from the image memory 81.

  On the other hand, when the switch S1 is turned on (step S111; Yes), it waits for the switch S2 that is an instruction operation to start photographing to be turned on (step S112). When the switch S2 is turned on (step S112; Yes), shooting is performed using the combination of flash light emitting units determined in step S110 that does not cause overexposure, and image data obtained by this shooting is stored in the memory card 83. (Step S113). Further, based on the image data obtained by the photographing in step S113, the photographed image is post-view displayed on the display device 11 (step S114). When shooting is performed in step S113 without returning to step S103 in step S111, the four frames of image data acquired in steps S105 to S108 after step S113 are deleted from the image memory 81.

  This completes the shooting of the intraoral image of one frame, and the process returns to step S101.

  In addition, when there are a plurality of combinations of flash light emitting units that do not cause whiteout, a combination of the flash light emitting units may be used to capture and record a plurality of images.

  As described above, an auxiliary light device having a plurality of light emitting units is used, and in response to a half-press operation of the release button, a plurality of images obtained by sequentially changing the light emission combinations of the light emitting units are acquired and acquired. Based on the result of evaluating a plurality of images, the light emission combination of the light emitting unit at the time of actual shooting is determined, and the light emission combination determined according to the full pressing operation of the release button which is an instruction operation for starting the shooting is used. By using an imaging device that performs shooting and recording, it is possible to obtain an imaging device that can automatically obtain a good intraoral image without halation by a simple operation of pressing a release button. Further, it is possible to leave only a good intraoral image as a record without wasting the capacity of the memory card.

  Further, the light emission combination of the light emitting units is a shadow when all the light emitting units emit light, when all the light emitting units do not emit light, or when the two light emitting units sandwiching the photographing optical axis are emitted. A good intraoral image having no part and no halation can be obtained.

  In this embodiment, a combination of flash light emitting units that can obtain an image with no whiteout is given priority. However, when whiteout occurs in any combination, whiteout determination is performed. For example, it may be configured such that the reference that the whiteout occurs due to the portion is changed such that the number of data of 230 or more is 5% or more of the total number of pixels. Further, a combination of flash light emitting parts with the least occurrence frequency of whiteout may be a combination at the time of actual photographing. By doing so, it is possible to shoot with a more narrow aperture than with steady-light shooting, so an image with a very small amount of whiteout is generated, but a deep depth of field can be secured. There is an effect.

(Second Embodiment)
Hereinafter, an imaging apparatus according to the second embodiment will be described. A schematic configuration of a camera 1 that is an imaging apparatus according to the second embodiment is the same as that shown in FIG.

  FIG. 6 is a flowchart showing the operation of the camera 1 according to the second embodiment in the shooting mode. A description will be given according to the flow shown in FIG.

  First, in step S101, it is confirmed whether or not the power is on. If the power is not on (step S101; No), that is, if the main switch button is operated, the process ends (step S401).

  If the power is on (step S101; Yes), a preview image is displayed (step S102). Next, it is determined whether or not the release button is depressed by one step, that is, whether or not the switch S1, which is a start instruction operation for photographing preparation operation, is turned on (step S103). If the switch S1 is not turned on (step S103; No), the process returns to step S101, and steps S101 to S103 are repeated.

  When the switch S1 is turned on (step S103; Yes), first, a shooting preparation operation is performed (step S104). The shooting preparation operation refers to focus adjustment (AF operation) for focusing on a subject and determination of exposure conditions for shooting.

  When the shooting preparation operation is completed, it is determined again whether or not the switch S1 is ON (step S205). If the switch S1 is not turned on (step S205; No), the process returns to step S103.

  On the other hand, when the switch S1 is turned on (step S205; Yes), it waits for the switch S2 that is an instruction to start photographing to be turned on (step S206). When the switch S2 is turned on (step S206; Yes), the image is taken with only steady light and recorded on the memory card (step S207). Next, all the four flash light emitting units 12a to 12d (see FIG. 1) emit light to shoot and record on the memory card (step S208). Next, the two flash light emitting units 12a and 12c across the optical axis are caused to emit light to record and record on the memory card (step S209). Further, the two flash light emitting units 12b and 12d across the optical axis are caused to emit light to record and record on the memory card (step S210). These steps S207 to S210 are preferably performed continuously in a short time.

  Next, each captured image is evaluated using the image data recorded in the memory card 83, and the evaluation result of each image is assigned to the tag information of each image (step S211). This evaluation is performed by the histogram generation unit 73 and the whiteout determination unit 74 in the evaluation unit 71 which is an evaluation unit in the image processing CPU 61 of the camera 1 shown in FIG.

  More specifically, the histogram generation unit reads an image recorded in the memory card 83 and generates a histogram for each image, and the whiteout determination unit 74 determines the presence or absence of a whiteout portion from the histogram. Details are the same as described in FIG. The tag information is recorded in, for example, an Exif file corresponding to each image, and describes whether each image has a whiteout portion.

  Next, the optimum image determined by the above evaluation, that is, a captured image without a whiteout portion is selected, and the image and tag information are displayed on the display device 11 in a post-view (step S212). In addition, when a plurality of optimum images, that is, a plurality of captured images without whiteout portions, are obtained, a slideshow display may be used.

  The selection of the optimum image based on this evaluation is performed when the image that has not been over-flashed is given priority among the images that have been flash-emitted, and the image that has been over-flashed has all been over-lighted. Only a captured image with only steady light is selected.

  As described above, an auxiliary light device having a plurality of light emitting units is used, and in response to an instruction operation to start shooting, the light emission combinations of the light emitting units are sequentially changed, and a plurality of shots are recorded and recorded. Evaluate multiple images, select an image without whiteout, and reproduce the selected image on the display means. By using the release button fully, no halation occurs. It is possible to obtain an imaging device that can easily obtain a simple intraoral image.

  Further, the light emission combination of the light emitting units is a shadow when all the light emitting units emit light, when all the light emitting units do not emit light, or when the two light emitting units sandwiching the photographing optical axis are emitted. A good intraoral image having no part and no halation can be obtained.

  Further, as a modification of the second embodiment, in step S211 of the flowchart shown in FIG. 6, a plurality of images recorded and recorded are evaluated and images are selected, and the unselected images are automatically stored in the memory. It may be deleted from the card and leave only the selected image. By doing so, it is possible to leave only a good intraoral image as a record without wasting the capacity of the memory card.
