TECHNICAL FIELD OF THE INVENTION
The present invention relates to a photographic processing apparatus and a photographic processing method having an image processing function.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, an image such as a human face is subjected to image processing using an image display medium on a certain image display medium by using a pattern recognition technology, and the image is corrected into an image that is easy to view on the image display medium, or the image is There are image processing techniques for modifying rights protection or adding artistic decoration.
[0003]
According to such an image processing technology, for example, in a technical field such as computer graphics, digital data is used as data relating to an image, and based on this data, the image is enlarged, reduced, rotated, inverted, projected, and shaded. And various other three-dimensional operations.
[0004]
Also, in the technical field of photographic processing devices, for example, the color of the pupil of the eye is corrected when the photographer is affected by strobe light at the time of photographing, or when the color contact is attached. Since there is a demand for producing prints, the above-described image processing technology is required.
[0005]
In the technical field of photographic processing apparatuses, image information recorded on a film in analog form is read using a scanner or the like to convert the image information into an electric signal, and the digital information obtained based on the electric signal is obtained. 2. Description of the Related Art A technique for producing a print by exposing and developing using image data obtained by performing image processing on data has become widespread.
[0006]
By the way, in such an image processing technology, various techniques for identifying and extracting a certain part of a human face, for example, only an eye, and performing image processing on only that region have been proposed as the pattern recognition technology advances. However, for example, by using a general-purpose and inexpensive device such as a personal computer, which has an image display means, it is possible to obtain a simple method that can be executed by an unskilled person without specialized knowledge as described below. It is difficult.
[0007]
That is, in the technical field of photographic processing, photographic processing apparatuses that automatically perform development and printing on photographic light-sensitive materials are rapidly spreading, and unskilled persons who do not have expertise in photographic processing and image processing can use such automatic processing. Since a color print is produced in a short time and at low cost by operating a photographic processing apparatus, it is required that even an unskilled person can easily operate the apparatus and perform image processing.
[0008]
For example, with reference to FIG. 5, a description will be given of a method of performing a certain image processing by specifying only the eyes of a human face image displayed on an image display medium with reference to FIG. Reference numeral 10 indicates an eye, and 20 indicates an eyebrow.
[0009]
In the image as described above, the operator visually recognizes the portion of the eye 10 and uses a pointing device such as a mouse, for example, as a plurality of points at positions as close as possible to the eye 10 around the eye region. R₁~ R₈And specify the plurality of points R₁~ R₈Are sequentially defined by defining a region surrounded by a polygon connected by line segments or the like, and the region of the eye 10 on the image is specified.
[0010]
At this time, since the image display medium digitizes the image obtained by the imaging device once as image data and re-images and displays the image, the image data is merely a numerical value. Therefore, when the plurality of points are specified on the image display medium, if the area other than the eye is specified widely, the area other than the eye is excluded when performing the image processing after specifying the area. A great deal of time is spent on data processing. Therefore, when specifying a plurality of points as described above, it is necessary to specify the points as close to the eyes as possible in order to execute data processing quickly and accurately.
[0011]
However, there is a problem in that skillfully specifying the plurality of points by a pointing device on an image display medium requires unexpected skill, and the specification is failed, and it takes a long time. Moreover, even if it takes a long time, the designation accuracy is not improved.
[0012]

[0027]
In the present specification, regarding the image of a human face, the head of the face (including the head) is referred to as the upper or lower part of the face (including the head), and the right or left of the face toward the image in accordance with the top and bottom of the human body. Shall be. Therefore, in this specification, the left or right of the face is not the right or left of the subject person.
[0028]
FIG. 1 is a block diagram schematically showing the configuration of a photographic processing apparatus according to the present invention. The photographic processing apparatus according to the present invention is similar to a conventionally known photographic processing apparatus except that it includes an image processing unit 50 described in detail below, and various chemical processes such as development, fixing, washing, and drying are performed. Device 61 that automatically performs physical processing or physical processing in a series of steps, performs color separation such that each pixel of a color image is approximately separated into three primary colors of blue, green, and red and photometry is performed. The control unit 70 includes a photographic processing unit 60 including a color scanner device 62 for reading out the light intensity of each of blue, green, and red as a color signal in order for each color.
[0029]
Then, after converting each color signal into a digital signal, after performing image processing as described later, the photographic photosensitive material is scanned and exposed based on the image processed image data, and the normal photographic processing is performed to perform color printing. And so on. The description of the processing device 61 and the color scanner device 62 is omitted, and the image processing unit 50 according to the present invention will be described below.
[0030]
The image processing unit 50 includes an image display unit 51, a pointing device 52, an arithmetic processing unit 53, and a storage unit 54. The operation of the entire photo processing device 1 is controlled by the control unit 70.
[0031]
First, the image display unit 51 reads image information recorded on a photographic photosensitive material such as a film as image information by a color scanner 62 or the like, and reads the image data read as digital data on a display device (hatched in the figure). ) To display an image, and is constituted by a CRT or a liquid crystal display device. In addition, an interface (not shown) capable of inputting and outputting statistical data relating to the target image and additional instructions and information relating to arithmetic processing and image processing to be described later may be provided along with the image display unit 51. .
[0032]
The pointing device 52 designates an arbitrary point on the image display unit 51, and is configured by a so-called mouse or trackball.
[0033]
In addition, the arithmetic processing unit 53 includes, in addition to arithmetic processing performed for processing for specifying an area on which image processing according to the present embodiment is performed on the image data (hereinafter, referred to as “image processing area specifying processing”), Performs various types of image processing such as color correction and density correction, image processing for processing specific to photographic images described later, and scaling, rotation, inversion, projection, shading, synthesis, and division generally performed on images. And various logic circuits, arithmetic circuits, registers and the like.
[0034]
In addition, the storage unit 54 stores not only basic numerical values based on statistical data relating to the target image according to the present embodiment, but also data in the middle of arithmetic processing such as the image data, data obtained by processing the basic numerical values, and the like. And comprises a RAM, a ROM, and the like. As described above, since the storage unit 54 stores the basic numerical values based on the statistical data regarding the target image, the position of the processing area can be estimated based on the statistical data without requiring any special complicated operation. . Since no special device or processing is required for the storage unit 54, the storage unit can be realized at low cost.
[0035]
Next, a basic concept of the image processing area specifying process performed by the image processing unit 50 according to the present embodiment will be described. In the present embodiment, a case will be described where a subject is a human face as an object of image processing, an eye image is specified from among the images, and image processing is performed on at least a part of the specified area.
[0036]
In the present embodiment, four points that are prerequisites for specifying the image processing area are specified, and the positional relationship of each part of the face based on the statistical data is used to reference the line segment determined by the four points. At the position where the region is statistically estimated, a tool such as a circle corresponding to the shape of the eye, an eyeglass-shaped icon, or a mask-shaped icon is displayed to specify the eye region. Hereinafter, first, the statistical data will be described.
[0037]
FIG. 2 is a plan view schematically showing a result of statistically examining a mutual positional relationship between the positions of the eyes 10, the nose 31, the mouth 32, and the like in the human face. In general, it is known that the positional relationship of the existence area, where the left and right eyes 10 exist in the human face, is almost constant from a statistical point of view.
[0038]
That is, as shown, when the line segment CD is set to be located on a line segment passing through the lower end of the left eye and the lower end of the right eye, the positions of both ends (the inner and outer corners of the eye) of the right eye and the position of the left eye The positions at both ends are four points P that divide the line segment CD into five equal parts₁, P₂, P₃, P₄Approximately corresponds to the position. That is,
h₁≒ h₂≒ h₃≒ h₄≒ h₅(1)
It is. Further, the line segment AC is almost equally divided by the line segment BD. Therefore,
AF ≒ DF ≒ FB ≒ FC ≒ v₁≒ v₂≒ 0.5V (2)
It is. Similarly, assuming that a, b, c, and d are constants that can be obtained statistically (setting values can be changed), the size L of the eye itself in the line segment BD direction (vertical direction of the face) is
L ≒ h₁≒ aH (a ≒ 0.2) (3)
And the eye is bh from the point F₁Ch from the point of (b ≒ 0.5)₁A positional relationship (positional relationship 1) of being located in an area up to the point of (c ≒ 0.5) is obtained.
[0039]
The size W of the eye itself in the line segment AC direction (lateral direction of the face) is equal to the lower end P of the eyebrows.₅And the lower end of the nose P₆And jaw C,
y₁≒ y₂≒ 0.5Y (4)
From
W @ dy₁(D ≒ 0.3) (5)
And the eye is dy when viewed from a position in contact with the line segment when viewed from the line segment BD.₁(Positional relationship 2).
[0040]
Therefore, the length of the line segment AC and the length of the line segment BD are respectively obtained on the displayed image, and based on the length data, the above-described formulas (1) to According to (5) and the positional relationships 1 and 2, an area in which the presence of an eye is estimated can be calculated by arithmetic processing and displayed as an image.
[0041]
Utilizing the statistical data on the positional relationship of each part of the face described above, four points are designated as follows, and a line segment defined by the four points is determined.
[0042]
That is, first, a point A on the top of the head, a point B on the chin, a line connecting the lower ends of both eyes and passing straight through the face on a straight line of a straight line passing up and down substantially at the center of the face. One point C of the end and one point D of the left end of the face are designated. The point C is located between the right eye and the edge of the face, and the point D is located between the left eye and the edge of the face. When the above four points are designated, a line segment AB connecting point A and point B, a line segment CD connecting point C and point D are determined, and an intersection F between line segment AB and line segment CD is determined. . At this time, the four points are set so as to be positions where a quadrilateral shape can be specified, and the diagonal lines have a positional relationship substantially orthogonal to each other. Since four points are designated at such positions, the designation operation is simple without skill.
[0043]
Next, using the line segment, based on the positional relationship of each part of the face based on the statistical data, an area where the eye area is estimated based on the line segment determined by the four points (hereinafter referred to as “estimated Area)) to specify the image processing specific area.
[0044]
That is, it is presumed that the left eye is above and in contact with the line segment DF, and the right eye is above and in contact with the line segment CF, and the position is determined by the positional relationship of each part shown in FIG. It is determined according to DF and CF. Based on the positional relationship between the parts, the estimated area of the eye is calculated and calculated according to the positions of the four points and the equations (1) to (5). At this time, the size of the estimation area is set so as to include the variation of the designated positions when the four points are designated, and to have a size such that the estimation area can include a true area.
[0045]
Therefore, since the processing area can be estimated by performing the arithmetic processing using a well-known arithmetic circuit or the like, the arithmetic processing unit or the like can be realized at low cost. Moreover, since the estimated position of the processing area is obtained by performing arithmetic processing on the basis of the line segment, the processing area can be quickly estimated by simple arithmetic processing, and the processing area can be specified in a short time without using a specially complicated device. . Further, since the processing area is estimated based on the statistical data, the processing area can be accurately estimated with statistical certainty.
[0046]
FIG. 3 is a flowchart showing the actual procedure (step 43) of performing image processing according to the basic concept of the image processing area specifying process described above in the order of steps. First, an image of a target face is captured as image data by a scanner or the like from an image recording means such as a film, and is displayed on the image display unit 51 as an image display medium (step 42).
[0047]
At this time, if the face is facing obliquely or down, the image is displayed in such a way that the image is corrected in such a direction that it is easy to specify four points by rotating it to the position almost facing the front on the image display. It may be displayed on the unit 51.
[0048]
Next, the aforementioned four points are designated by a pointing device 52 such as a mouse (step 43a). At this time, four points are designated sequentially from the top of the head in a predetermined direction. However, the order itself is not limited as long as which one of the four points is the crown or chin is appropriately defined. The designated position needs to be inside the face area, but may be a slightly shifted position as long as it is inside. For example, in the case of the top of the head, a position on the contour line of the face is preferable, but a slightly shifted position, that is, a hair portion may be used. By specifying the four points in this manner, as described above, a positional relationship and a line segment obtained by performing arithmetic processing from statistical data based on the positional relationship of each part of the face are determined (step 43b). The position of the eye is statistically estimated with reference to and is displayed as an image processing area (step 43c).
[0049]
At this time, in order to make it easier to see the relationship between the estimated area of the eyes and the contour of the face on the image display unit, an icon indicating the estimated area can be displayed at the same time as displaying the face image. This icon may be a simple circle (FIG. 4A) as shown in FIGS. 4A to 4C, an icon in which the estimation area is shaped like glasses (FIG. 4B), or , An icon in the form of a mask having an opening in the estimation area (FIG. 4 (c)) or the like can be set. The shape of the estimation region may be a circle or an ellipse, or may be a shape that approximates the shape of the eye and is close to the contour of the eye.
[0050]
If the shape of the estimation area is a circle or an ellipse, an icon can be easily set, and the storage capacity of the storage unit is not pressed. Further, if the shape of the estimation area is a spectacle shape, the image expression can be easily imagined when performing image processing, so that image processing can be easily performed. Furthermore, if the shape of the estimation area is a mask-shaped icon with an opening, image processing operations can be performed without being affected by the flesh color portion, so that image processing can be easily performed.
[0051]
In this way, if the estimated area correctly contains the eyes, the processing area is specified. At this time, the position and size of the eyes and the positional relationship between the eyes may be shifted from the statistical estimation region due to the variation of the age and gender of the subject person. By the operation, the position of the glasses or the position of the opening of the mask-shaped icon can be displaced, or the size can be enlarged or reduced to approximate the position and size of the display image (step 43d). Therefore, it is possible to display the estimated area so that the positional relationship with the display image can be easily understood, and adjust the size and the position.
[0052]
After specifying the processing area as described above, at least a part of the processing area, for example, extracting an eye or a pupil, changing the color of the part, enlarging or reducing the part, The image data can be formed by performing image processing such as adding a partial image (step 44).
[0053]
That is, it is possible to judge that the circular area inside the eye is the pupil and change the color of the pupil arbitrarily to remove red-eye or to attach a color contact. Further, the contrast between the pupil region and the adjacent region can be enhanced with black and white. In addition, adding a white point in the pupil to produce a so-called catchlight effect, enlarging only the periphery of the eye to make it a patchy eye, or conversely changing the periphery of the eye to a small eye Can be.
[0054]
As described above, it is possible to specify a region to be image-processed in a relatively short time by designating a smaller number of designated points than those of the conventional method at a position that is easy to designate by a simple algorithm. . In addition, since the position of the designated point is not particularly complicated, it is possible to easily specify an area for image processing without requiring skill.
[0055]
As described above, in the present embodiment, the case where the image processing area is the two eyes of the subject person has been described, but the present invention is not limited to this configuration, and the image processing area may be one eye, nose or mouth. And so on. That is, if data on the positional relationship of each part of a certain object can be obtained quantitatively by a statistical method or the like and the data can be used to estimate the area of each part, the target image is not only a person, but also an animal or plant. For an inanimate object such as a building or an article, as well as an inanimate object, the area can be specified only by specifying four points that can define the positional relationship of each part as in the case of a human face.
[0056]
