[0032]
The diagnostic button 51 corresponds to an instruction unit of the present invention.
[0033]
Next, the operation of the digital camera 10 according to the above embodiment will be described.
[0034]
FIG. 3 shows a processing routine executed by the CPU 20. When the digital camera 10 is turned on by the power switch 50, the processing routine shown in FIG. In step 100, it is determined whether or not a diagnostic mode instruction has been made. If the determination is negative, this routine is terminated. If the determination is affirmative, the process proceeds to step 102. The determination in step 100 can be made by determining whether or not a pressing operation is performed by receiving a signal from the diagnostic button 51. In step 102, a through image display process for displaying a moving image (through image) obtained by continuous imaging by the CCD 12 on the LCD 34 is executed.
[0035]
Next, in step 104, it is determined whether or not an on-screen mode is instructed. The on-screen mode instruction is an instruction for displaying the target image on the LCD 34. The determination in step 104 can be made by determining a pressing instruction of the switch 40.
[0036]
For example, a menu including an on-screen mode item is displayed on the LCD 34, and after the on-screen mode item is selected from among the displayed menu items by the operation of the up / down / left / right key 54 by the user, the execution button 56 is pressed. Output an on-screen mode instruction signal. By determining whether or not this on-screen mode instruction signal has been output, it is possible to determine whether or not an on-screen mode instruction has been issued. In this case, various menu items for instruction selection may be displayed on the LCD 34 when the user presses the menu button 52.
[0037]
If the determination in step 104 is negative, the process proceeds to step 108. If the determination is positive, the process proceeds to step 106, and the target image stored in the storage unit 22 is displayed on the LCD 34, and then the process proceeds to step 108. By the processing in step 106, the target image 64 as shown in FIG. 4 is displayed on the LCD 34 together with the through image. For this reason, it is possible to prompt the user (photographer) to position the person's face as the subject at the time of photographing.
[0038]
The target image is obtained by, for example, photographing a user's face to be subjected to the face color diagnosis process in advance by a normal photographing process, and using an edge detection process or the like from the obtained user's face image. The contour information of the eyes and the whites may be extracted and stored. In addition, outline information indicating outlines of general human faces, eyes, and white-eye portions may be stored in advance as a target image.
[0039]
Next, in step 108, it is determined whether or not a shooting instruction has been issued. It is possible to determine whether or not this photographing instruction has been made by determining whether or not a pressing operation has been performed by receiving a signal from the release switch 48.
[0040]
If the result in Step 108 is negative, the program proceeds to Step 126, where other processing is executed and this routine is terminated. The other processing is to execute other processing equipped in the digital camera 10, and includes, for example, processing such as color correction processing of image data.
[0041]
On the other hand, if the result in step 108 is affirmative, the process proceeds to step 110, where the shooting process is executed to obtain image data of the shot image. This shooting process is performed by driving various driving units (not shown) of the digital camera 10 such as focus adjustment (not shown) from the CCD 12 when shooting a subject, zoom, angle of view adjustment using a lens, and exposure adjustment. Image data of an image is obtained. At the time of shooting, the strobe 36 automatically emits light under the control of a strobe control unit (not shown). For this reason, the photographing process is executed under a certain condition in which the influence of ambient light can be suppressed.
[0042]
In the present embodiment, in order to describe the case where the user's face is used as the subject, the image data of the captured image including the image showing the user's face is obtained by the imaging process in step 120.
[0043]
Next, in step 112, a specific area setting process is executed. In the process of step 112, the extraction unit 24 sets a specific area from the captured image of the image data obtained in step 110. In the present embodiment, in order to describe the case where the white eye part and the cheek part of the image indicating the user's face are adopted as the specific area, areas corresponding to the white eye part and the cheek part are set. The specific area setting process in step 112 is obtained by, for example, storing in advance the contour information for recognizing the cheek part and the white eye part of the face in the storage unit 22 and photographing the contour information that matches the stored contour information. The image data of the captured image may be specified, and the image data of the image within the contour of the specified contour information may be set as the specific region.
[0044]
At this time, an area including areas corresponding to the cheeks and whites of the photographed image is estimated according to the target image displayed on the LCD 34 in step 106, and the image data of the image in the estimated area is estimated. The image data of the image in the contour of the contour information that matches the contour information stored in advance in the storage unit 22 may be set as the specific region. In this way, the specific area can be set with high accuracy, and measurement errors can be reduced.
[0045]
Next, in step 114, diagnostic data is calculated from the image data of the image included in the specific area set in step 112. In the present embodiment, the yellow component data included in each of the image data of the white eye part and the cheek part is calculated.
[0046]
Next, in step 116, a storage process is executed for storing the diagnostic data for the specific area calculated in step 114 in the storage unit 22. In the process of step 116, the diagnostic data of the specific area calculated in step 114 is stored in association with the date information read from the timer 32 for each specific area. In the present embodiment, the data of the yellow component of each image of the white eye part and the cheek part is stored in association with the date information.
[0047]
By the processing of step 116, the diagnostic data of the specific area of the user's face at the time of shooting is stored in association with date information indicating the date at the time of shooting.
[0048]
Next, in step 118, a reference data reading process for reading the reference data stored in the storage unit 22 is executed. In the present embodiment, a case will be described in which yellow component data calculated from image data of general white eye and cheek images of a healthy person stored in advance is used.
[0049]
Next, in step 120, the diagnostic data of the image included in the specific area calculated in step 114 is compared with the reference data read in step 118. Next, in step 122, the fluctuation amount is calculated according to the comparison processing result in step 120. This fluctuation amount is a value indicating the fluctuation of the diagnostic data calculated in step 114 from the reference data. For example, the fluctuation amount is calculated by setting the reference data to “1”. In the present embodiment, a value (variation amount) indicating a variation from the reference data of each of the yellow component data of the white eye portion and the cheek portion is calculated.
[0050]
Next, at step 124, after the display process for displaying the fluctuation amount calculated at step 122 on the LCD 34 is executed, this routine is finished.
[0051]
For example, the amount of change shown in FIG. 6 is displayed by the display process in step 124, and an image 60 showing the amount of change in the white-eye part and cheek part is displayed on the LCD 34. More specifically, an image 60A indicating a value indicating the variation amount “0.65” of the white eye compared with the reference data “1” is displayed, and the variation amount “0” of the cheek compared with the reference data “1”. An image 60C showing a value indicating .45 "is displayed.
[0052]
As described above, in the present embodiment, a specific area in the face image of the person in the captured image of the image data obtained by imaging is set, and diagnostic data is obtained from the image data of the image in the specific area. The calculated diagnostic data and the reference data are compared, and the variation amount of the diagnostic data from the reference data is displayed on the LCD 34. For this reason, the digital camera 10 can easily notify the user of self-diagnosis data with a simple configuration. Therefore, it is possible to notify the user of data that allows the user to self-determine the degree of improvement of the disease, the physical condition of the user, and the like.

This corresponds to the function of the means. The determination in step 100 corresponds to the function of the instruction means of the present invention.
[0054]
The present invention is not limited to the above embodiment. For example, in the present embodiment, the case where the yellow component data of the image data of the general white eyes and cheeks of a healthy person stored in advance in the storage unit 22 is used as the reference data in step 118 above. Although explained, it is not limited to this.
[0055]
For example, by converting from the date information of the diagnostic data stored in the above step 116, the diagnostic data of a specific area corresponding to the date information of a predetermined number of days ago, such as the previous day, the day before two days, or one month before, is used as the reference data. It may be used. Moreover, you may make it use the average value of the diagnostic data of the specific area | region corresponding to the date information of these several predetermined days ago as reference | standard data.
[0056]
In this way, for example, the previous day, the day before, the month before, or the fluctuation amount indicating the fluctuation from the average value of the diagnostic data is displayed on the LCD 34, and the fluctuation amount is displayed to the user. Can be notified.
[0057]
In addition, at the time of displaying the calculated fluctuation amount on the LCD 34 in the above-described step 124, the diagnostic data of the day before, the day before, and the month before the photographing date are displayed together with the variation amount of the diagnostic data on the day when the photographing is performed.
