[Basic configuration]

  Referring to FIG. 1, the size measuring apparatus of the present invention is basically configured as follows. The first capturing means 1 captures an object scene image in which a whole body image of a designated person appears. The accepting means 2 accepts an input operation for inputting the height of the designated person in relation to the capturing process of the first capturing means. The first measuring unit 3 measures the size of the specific part of the designated person based on the object scene image captured by the first capturing unit and the height input by the input operation. The second capturing means 4 captures an object scene image in which a specific part of a designated person and a desired object appear. The second measuring unit 5 measures the size of a desired object based on the object scene image captured by the second capturing unit and the size measured by the first measuring unit.

If the height of the designated person is input and an object scene image in which the whole body image of the designated person appears is taken in, the size of the specific part of the designated person is measured. After that, if the object scene image in which the specific part of the designated person and the desired object appear is taken in, the size of the desired object is measured. Thereby, the size of a desired object can be easily measured.
[Example]

  Referring to FIG. 2, the digital camera 10 of this embodiment includes a focus lens 12 and an aperture unit 14 driven by drivers 18a and 18b, respectively. The optical image of the object scene is irradiated onto the imaging surface of the image sensor 16 through these members.

  When the camera mode is selected by the mode changeover switch 38md provided in the key input device 38, the CPU 40 activates the driver 18c to execute the moving image capturing process under the imaging task. In response to the vertical synchronization signal Vsync generated every 1/60 seconds, the driver 18c exposes the imaging surface and reads out the charges generated on the imaging surface in a raster scanning manner. From the image sensor 16, raw image data representing the object scene is output at a frame rate of 60 fps.

  The signal processing circuit 20 performs processing such as color separation, white balance adjustment, and YUV conversion on the raw image data from the image sensor 16 to create image data in YUV format. The created image data is written into the SDRAM 24 through the memory control circuit 22.

  The LCD driver 26 repeatedly reads out the image data stored in the SDRAM 24 through the memory control circuit 22 and drives the LCD monitor 28 based on the read image data. As a result, a real-time moving image (through image) representing the scene is displayed on the monitor screen.

  The signal processing circuit 20 also supplies the CPU 40 with Y data generated by YUV conversion. The CPU 40 performs simple AE processing on the Y data and calculates an appropriate EV value. The aperture amount and the exposure time that define the calculated appropriate EV value are set in the drivers 18b and 18c, respectively, and thereby the brightness of the through image is appropriately adjusted.

  When the shutter button 38s is half-pressed, the CPU 40 performs strict AE processing on the Y data given from the signal processing circuit 20, and calculates the optimum EV value. The aperture amount and the exposure time that define the calculated optimal EV value are set in the drivers 18b and 18c, respectively, as described above. As a result, the brightness of the through image is adjusted strictly.

  Subsequently, the CPU 40 performs AF processing on the high frequency component of the Y data given from the signal processing circuit 20. The focus lens 12 is moved in the optical axis direction by the driver 18a, and is arranged at the focal point. As a result, the sharpness of the through image is improved.

  When the shutter button 38s is fully pressed, the CPU 40 executes a still image capturing process. Image data representing the object scene when the shutter button 38s is fully pressed is saved in a work area (not shown) formed in the SDRAM 24.

  Thereafter, the CPU 40 activates the I / F 30 in order to execute the recording process. The I / F 30 reads the image data saved in the work area through the memory control circuit 22 and records the read image data on the recording medium 32 in a file format. When the recording process is completed, the display of the through image is resumed.

  When the playback mode is selected by the mode changeover switch 38md provided in the key input device 38, the CPU 40 executes the following processing under the playback task. First, the CPU 40 designates the latest image file recorded on the recording medium 32 as a reproduction image file, and instructs the I / F 30 and the LCD driver 26 to execute reproduction processing focusing on the designated image file.

  The I / F 30 reads the image data of the designated image file from the recording medium 32 and writes the read image data to the SDRAM 24 through the memory control circuit 22. The LCD driver 26 reads the image data stored in the SDRAM 24 through the memory control circuit 22 and generates an optical image corresponding to the read image data. As a result, the generated optical image is displayed on the LCD monitor 28.

  By the operation of the key input device 38 by the operator, the CPU 40 designates a subsequent image file or a preceding image file as a reproduction image file. The designated image file is subjected to a reproduction process similar to that described above, and as a result, the display on the LCD monitor 28 is updated.

  As an operation mode of the digital camera 10, a size setting mode is prepared for performing processing for calculating the size between both eyes of a person captured by the imaging surface. A register RGST shown in FIG. 3 is provided for processing in the size setting mode.

  When the size setting mode is selected by the operation of the key input device 38 by the operator, the graphic generator 34 outputs graphic data representing the cursor CS1 and graphic data representing the cursor CS2 to the LCD driver 26.

  As a result, the guide line GL1 including the cursor CS1 and the cursor CS2 is displayed on the screen of the LCD monitor 28. Referring to FIG. 4A, cursor CS1 and cursor CS2 are each composed of a horizontal line segment. The cursor CS1 is displayed at the upper center of the screen, and the cursor CS2 is displayed at the lower center of the screen. Note that the number of pixels between the cursor CS1 and the cursor CS2 is represented by HT1.

  The operator of the digital camera 10 adjusts his / her standing position while observing the display on the LCD monitor 28 so that the whole body image of the person HB appearing on the imaging surface fits in the guideline GL1 (FIG. 4B )reference). That is, adjustment is performed so that the top of the person HB is in contact with the cursor CS1 and the foot is in contact with the cursor CS2. By adjusting in this way, the height of the person HB appearing on the imaging surface can be represented by the number of pixels HT1 between the cursor CS1 and the cursor CS2.

  The face detection circuit 36 is configured as shown in FIG. The face detection circuit 36 moves the verification frame FD from the start position to the end position of the object scene image stored in the SDRAM 24 in a raster scanning manner, and some images belonging to the verification frame FD are registered in the dictionary 36d. Check against the face image.

  First, the search area is set so as to cover the entire evaluation area EVA. Further, the face detection frame FD has a size that changes in the range of “200” to “20”, and is scanned in the raster direction on the evaluation area EVA in the manner shown in FIG.

  When the image of the verification frame FD matches the registered face image, the face detection circuit 36 registers the current size and position of the verification frame FD in the register 36e. The collation frame FD is reduced every time it reaches the end position, and then set again at the start position. When the minimum size collation frame FD reaches the end position, a search end notification is returned from the face detection circuit 36 to the CPU 40.

  When the shutter button 38s is fully pressed in the state where the size setting mode is selected, the CPU 40 responds to the search end notification returned from the face detection circuit 36 and determines whether or not the search for the face of the person HB has succeeded. Is determined. If at least one matching frame FD is registered in the register 36e, it is determined that the face image search has been successful. On the other hand, if the matching frame FD is not registered in the register 36e, it is determined that the face image search has failed.

  When the face image search fails, the CPU 40 notifies the operator that the size calculation between both eyes is impossible.

  When the search for the face image is successful, it is determined whether or not the position of the matching frame FD is within an allowable range where the face of the person HB is expected, for example, immediately below the cursor CS1. This is because the number of pixels HT1 between the cursor CS1 and the cursor CS2 does not match the height of the person HB appearing on the imaging surface when the position of the matching frame FD, that is, the face position of the person HB is at the center or lower part of the screen.

  If it is within the allowable range, the CPU 40 detects the black-eye portions of both eyes of the person HB in the image of the verification frame FD set in the register 36e, and detects the number of pixels WD_ey1 therebetween (see FIG. 7). .

  Next, the CPU 40 causes the LCD monitor 28 to display a message prompting the user to input the height of the person HB.

As described above, the height of the person HB appearing on the imaging surface can be represented by the number of pixels HT1. Therefore, the size WD_ey0 between the actual eyes of the person HB is obtained by using the actual height HT0 of the person HB, the size WD_ey1 between the eyes of the person HB appearing on the imaging surface, and the height HT1 of the person HB appearing on the imaging surface. The following equation 1 can be used.

  When the operator inputs the height of the person HB through the key input device 38, the CPU 34 calculates the size WD_ey0 between the eyes, and sets the calculated size WD_ey0 between the eyes in the register RGST.

  In parallel with the imaging task described above, the CPU 40 measures the size of the desired object under the size calculation task.

  When the setting of the size WD_ey0 between both eyes in the register RGST is completed, the size of a desired object can be measured. First, the object whose size is to be measured and the person HB are arranged side by side so as to be equidistant from the digital camera 10. The operator of the digital camera 10 confirms that the object and the face of the person HB are within the same angle of view while watching the through image display on the LCD monitor 28. For example, when it is desired to measure the size of the fish FS, with reference to FIG. 7, a state where the person HB holds the fish FS with both hands and holds it next to the face can be considered. The details of the process of measuring the size of the object will be described below using the example of FIG.

  When a touch operation is performed on the monitor screen while the through image is displayed on the LCD monitor 28, the touch position is detected by the touch sensor 38 and the detection result is given to the CPU 40.

  When the operator touches both ends in the horizontal direction of the fish FS appearing on the imaging surface, it is determined whether or not the size WD_ey0 between the eyes is set in the register RGST. If not set, the CPU 40 notifies the operator that the object size cannot be measured.

  If the size WD_ey0 between the eyes is set, the graphic generator 34 outputs graphic data representing the cursor CS3 and graphic data representing the cursor CS4 to the LCD driver 26.

  As a result, the guide line GL2 including the cursor CS3 and the cursor CS4 is displayed on the screen of the LCD monitor 28. Referring to FIG. 8, cursor CS3 and cursor CS4 are each composed of a vertical line segment. In addition, the cursor CS3 and the cursor CS4 are respectively displayed at the ends touched by the operator, that is, at both ends of the fish FS appearing on the imaging surface. Note that the number of pixels between the cursor CS3 and the cursor CS4 is represented by WD_obj1.

  The face detection circuit 36 searches for the face image of the person HB in the image displayed on the LCD 28 as in the processing in the size setting mode. If the face image search fails, the CPU 40 notifies the operator that the object size cannot be measured.

  If the search for the face image is successful, the CPU 40 detects the black eye portions of both eyes of the person HB in the image of the matching frame FD and detects the number of pixels WD_ey2 between them, as in the processing in the size setting mode. To do.

  Since the guide line GL2 indicates both ends of the fish FS appearing on the imaging surface, both ends of the actual fish FS arranged side by side with the face of the person HB have the guide line GL2 at the face position of the person HB and the light of the digital camera 10. It corresponds to what was projected on the plane orthogonal to the axis.

  Therefore, the actual size WD_obj0 of the fish FS can be calculated by obtaining the distance between the cursor CS3 and the cursor CS4 projected on the plane perpendicular to the optical axis of the digital camera 10 at the face position of the person HB.

Therefore, the actual size WD_obj0 of the fish FS is the actual size WD_ey0 between the eyes of the person HB set in the register RGST, the size WD_ey2 between the eyes of the person HB appearing on the imaging surface, and between the cursor CS3 and the cursor CS4. Can be obtained by the following equation (2) using the number of pixels WD_obj1.

  The CPU 40 displays on the LCD monitor 28 the size WD_obj0 of the fish FS obtained in this way.

  The CPU 40 executes a plurality of tasks including an imaging task shown in FIGS. 8 to 10, a reproduction task shown in FIG. 11, and a size calculation task shown in FIG. Note that control programs corresponding to these tasks are stored in the flash memory 44.

  Referring to FIG. 8, in step S1, the moving image capturing process is started, and in step S3, the face detection circuit 36 is activated. In step S5, it is determined whether or not the size setting mode is selected. If the determination result is NO, the process proceeds to step S9. If YES, the guideline GL1 is displayed on the LCD monitor 28 in step S7.

  In step S9, it is determined whether or not the shutter button 38s is half-pressed. As long as the determination result is NO, the simple AE process is repeatedly executed in step S11. The brightness of the through image is appropriately adjusted by the simple AE process.

  When the determination result is updated from NO to YES, a strict AE process is executed in step S13, and an AF process is executed in step S15. As a result of the strict AE process and the AF process, the brightness and focus of the through image are strictly adjusted.

  In step S17, it is determined whether or not the shutter button 38s is fully pressed. If the determination result is NO, the process proceeds to step S19, and if YES, the process proceeds to step S21.

  In step S19, it is determined whether or not the shutter button 38s has been released. If the determination result is YES, the process returns to step S5, and if NO, the process returns to step S17.

  In step S21, a still image capturing process is executed. In step S23, it is determined whether or not the operation mode is the size setting mode. If the determination result is NO, the recording process is executed in step S25, and then the process returns to step S5.

  If the determination result of step S23 is YES, it will be determined whether the search of the face of the person HB was successful in response to the search end notification returned from the face detection circuit 36 in step S27. If the determination result of step S27 is YES, it will progress to step S29, and if it is NO, it will alert | report to an operator that the size calculation between both eyes is impossible in step S31.

  In step S29, it is determined whether or not the position of the verification frame FD is within an allowable range in which the position of the verification frame FD is expected to be the face of the person HB. If the determination result is NO, the process proceeds to step S31, YES If so, the process proceeds to step S33.

  In step S33, the black eyes of both eyes of the person HB are detected to detect the number of pixels WD_ey1 therebetween, and in step S35, a message prompting the user to input the height of the person HB is displayed on the LCD monitor 28.

  In step S37, it is repeatedly determined whether or not the operator has input the height of the person HB through the key input device. When the determination result is updated from NO to YES, the process proceeds to Step S39.

  In step S39, the size WD_ey0 between the eyes of the person HB is calculated using the actual height HT0 of the person HB, the size WD_ey1 between the eyes appearing on the imaging surface, and the height HT1 of the person HB appearing on the imaging surface. In step S41, the calculated size WD_ey0 between the eyes is set in the register RGST, and then the process returns to step S5.

  Referring to FIG. 11, in step S51, a number indicating the latest image file is set in variable K, and in step S53, the image file of the Kth frame recorded on recording medium 32 is reproduced.

  In step S55, it is repeatedly determined whether or not the operator has performed an operation to update the reproduction file. When the determination result is updated from NO to YES, the variable K is incremented or decremented in step S57, and the process returns to step S83.

  Referring to FIG. 12, in step S61, it is repeatedly determined whether or not the operator has performed an operation of designating an object by touching the monitor screen. If the determination result is updated from NO to YES, the register is updated in step S63. It is determined whether or not the size WD_ey0 between both eyes of the person HB is set in RGST.

  If the decision result in the step S63 is NO, it notifies the operator that the object size cannot be measured in a step S65, and the process returns to the step S61. If YES, the guideline GL2 is displayed at the location touched by the operator in step S67.

  In step S69, it is determined whether or not the search for the face of the person HB has been successful in response to the search end notification returned from the face detection circuit 36. If the determination result is NO, the process proceeds to step S65. In step S71, the black eye portions of both eyes of the person HB appearing on the imaging surface are detected, and the number of pixels WD_ey2 between them is detected. In step S73, the number of pixels WD_obj1 between the cursor CS3 and the cursor CS4 is detected.

  In step S75, the actual size WD_ey0 between both eyes of the person HB set in the register RGST, the size WD_ey2 between both eyes appearing on the imaging surface, and the number of pixels WD_obj1 between the cursor CS3 and the cursor CS4 are designated. The actual size WD_obj0 of the detected object is calculated. In step S77, the calculated actual size WD_obj0 of the object is displayed on the LCD monitor 28, and then the process returns to step S61.

  As can be seen from the above description, the CPU 40 captures an object scene image in which the whole body image of the designated person appears (S3, S21, S27, S29, S111, S113), and captures an input operation for inputting the height of the designated person. Accepted in connection with processing (S35, S37). Further, the CPU measures the size of the specific part of the designated person based on the captured object scene image and the height input by the input operation (S33, S39, S41), and the specific part of the designated person and the desired part are measured. The object scene image in which the object appears is captured (S1, S3, S69). Further, the CPU measures the size of a desired object based on the captured object scene image and the measured size (S71 to S75).

  If the height of the designated person is input and an object scene image in which the whole body image of the designated person appears is taken in, the size of the specific part of the designated person is measured. After that, if the object scene image in which the specific part of the designated person and the desired object appear is taken in, the size of the desired object is measured. Thereby, the size of a desired object can be easily measured.

  In this embodiment, the object size is calculated while the through image is displayed on the LCD monitor 28. However, the object in the image recorded on the recording medium 32 is calculated during the reproduction. May be. In this case, the reproduction task shown in FIGS. 13 and 14 is executed instead of the reproduction task shown in FIG. 11 and the size calculation task shown in FIG. Note that steps S81 to S87 in FIG. 13 are the same processes as steps S51 to S57 in FIG. Steps S89, S91, and S95 to S105 are the same processes as steps S61, S67, S69, S65, and S71 to S77 in FIG. Step S93 is the same process as step S3 of FIG.

  In this embodiment, the actual size between both eyes of a person is calculated and used to measure the size of the object. However, the size of another part of the person may be calculated and used. For example, it may be the width of the face or the size between both nostrils.

  In this embodiment, if the size between the eyes of the person is set in the register, the size of the object is calculated using the size. However, when setting the size between the eyes, the feature information of the person's face is also stored in a flash memory or the like, and the newly detected face matches the set face when measuring the size of the object. It may be determined using stored feature information. Then, it is only necessary to calculate the size of the object only when the faces match in the discrimination result. However, in this case, the processing of steps S111 and S113 shown in FIG. 15 is executed between steps S29 and S33 shown in FIG. 10, and the processing shown in FIG. 16 is performed between steps S69 and S71 shown in FIG. It is necessary to execute the processes of steps S121 to S125.

  Referring to FIG. 15, the feature information of the face of person HB is detected in step S <b> 111, and the detected feature information is stored in flash memory 44 in step S <b> 113. Referring to FIG. 16, in step S121, the facial feature information of the person HB is detected, and in step S123, the newly detected facial feature information and the facial feature information stored in the flash memory 44 are obtained. Match. In step S125, it is determined whether or not the collation result exceeds the reference level REF. If the determination result is NO, the process proceeds to step S65, and if YES, the process proceeds to step S71.

  In this embodiment, the state in which the person is facing the front with respect to the digital camera 10 has been described as an example. However, as long as the face can be detected as a person's face, the person may face to the side or the side. In this case, an image of a face orientation pattern other than the front orientation is also registered in the dictionary 36d, and the face orientation of the person on the imaging surface can be specified by collating these images. Furthermore, by correcting the calculated size between both eyes according to the face direction, the size between both eyes and the size of the object can be calculated more accurately.

  In this embodiment, the digital still camera has been described. However, the present invention can also be applied to a digital video camera.
