JP 2000-324339 A (paragraph numbers [0034], [0040], FIG. 5)

  As described in Patent Document 1, not only for the purpose of correcting aberrations and the like due to the characteristics of the lens used for shooting, but also when considering artificial image processing such as retouching, it is the target of processing. By enlarging only the area and displaying it on the display, it is possible to easily determine whether correction is necessary or not, and to facilitate delicate processing when correction is performed.

  Here, when the lateral chromatic aberration correction described in Patent Document 1 is considered, the lateral chromatic aberration appears more prominently in a portion that is separated from the center of the image of the image data. In the case of the image data, there is a case where it is desired to grasp the state of chromatic aberration in each of the four corners on the image in the image data by enlarging them on the display. However, since the conventional image processing apparatus has only a function of enlarging the entire image data or enlarging and displaying only a specified single region, for example, four corners on the image of the image data Even when the above state is confirmed, an operation such as scrolling the displayed image data is required, which is troublesome for the operator.

  An object of the present invention is to rationally configure an apparatus, a method, and a program that can easily display an enlarged image of each part even when correcting a plurality of places on an image of image data.

  A feature of the present invention is that, in an image processing apparatus including a display unit that executes processing for displaying image data on a display, the display unit specifies a plurality of locations on an image of image data to be processed, and There is a point that multi-display means for displaying a plurality of enlarged images in which the designated portion is enlarged on the display is provided.

  With this configuration, a plurality of locations on the image of the image data to be processed are specified, and a plurality of enlarged images obtained by enlarging the specified locations are displayed on the display, whereby a plurality of positions that are spaced apart on the image are displayed. An enlarged image of the area can be confirmed on the display at the same time. As a result, when checking the state of the image data, it is not necessary to perform the trouble of scrolling or manually specifying the area to be enlarged.

  In the present invention, as the multi-display unit, a process of setting the designated portion based on a plurality of locate data, enlarging the image data of the designated portion, and listing and displaying the enlarged image on the display. It is possible to configure such that at least one of the data value of the locate data, the number of locate data, and the enlargement ratio of the enlarged image can be arbitrarily changed.

  With this configuration, if the locate data can be changed, an enlarged image of an arbitrarily set area can be displayed on the image, and an arbitrarily set position and an arbitrarily set number of image data can be arbitrarily set. Since it is displayed as a list at a rate, for example, compared with displaying enlarged images of preset areas on a display in a distributed manner, enlarged images of image data of necessary areas are aggregated and displayed on the display This makes it easy to grasp the details of the image data.

  In the present invention, as the display unit, the image data is displayed on the display as a source image, an enlargement target area indicating the plurality of designated portions is displayed on the source image, and the multi-display unit includes the plurality of display units. An interface may be provided for changing the locate data by arbitrarily designating any one of the enlargement target areas and moving it on the source image.

  With this configuration, it is possible to easily determine the position of the enlarged image corresponding to the position of the source image from the enlarged target area displayed on the source image displayed on the display. The enlargement target area can be arbitrarily set by a simple operation such as moving on the source image by operating the mouse or the like while being selected by the cursor.

  The present invention includes, as the image processing apparatus, chromatic aberration correcting means for correcting chromatic aberration of the optical lens system that generated the image data, and the multi-display means is a position farthest from the center position on the image of the image data. The processing form may be set so as to set the designated portion in order to display the image as an enlarged image.

  With this configuration, since the position farthest from the center position of the image data is set as the designated location, the image of the region where the chromatic aberration is most noticeable can be enlarged and visually confirmed, and the chromatic aberration correction means corrects the chromatic aberration of the image data In this case, the state of aberration and the state of correction can be accurately grasped from a plurality of enlarged images.

  In the image processing method for displaying image data on a display, the present invention executes a step of enlarging the image data at the designated location after the designation step for designating a plurality of locations of the image data to be processed. Then, a display step of displaying the enlarged image on the display may be executed.

  With this configuration, by executing the designation step, the enlargement step, and the display step, a plurality of locations on the image of the image data can be enlarged and displayed on the display, and the enlarged images of a plurality of regions that are separated from each other on the image Can be confirmed simultaneously on the display. As a result, when checking the state of the image data, it is not necessary to perform the trouble of scrolling or manually specifying the area to be enlarged.

  The present invention relates to an image processing program for causing a computer to execute processing for displaying image data on a display, and a function for specifying a plurality of locations of the image data to be processed, and a function for enlarging image data at the specified location. And a function of displaying the enlarged image data of the plurality of places on a display may be executed by a computer.

  With this configuration, a plurality of locations on the image of the image data to be processed are specified, the image data at the plurality of locations is enlarged, and the image data thus enlarged is displayed on the display. As a result, when checking the state of the image data, it is not necessary to perform the trouble of scrolling or manually specifying the area to be enlarged.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Yes. A media drive 7 corresponding to the structure of the storage means is provided at the upper position of the processing device 4 so as to acquire information from a disk type medium such as a CD, MO or FD, or to acquire information from a semiconductor type medium. The image processing unit A is configured by these.

  The film scanner 2 has a light source unit 2A having a light emitting diode, a halogen lamp, and the like at the bottom, a zoom lens 2B at the middle, and image information from the zoom lens at the top, R (red) and G ( A line CCD type photoelectric conversion unit 2 </ b> C that captures image data separated into three primary colors (green) and B (blue) is disposed. In the film scanner 2, when scanning the photographic film F, the film carrier 8 suitable for the size of the photographic film F is mounted on the upper surface of the light source unit 2A, and scanning is started. In synchronism with the operation of conveying in the sub-scanning direction (longitudinal direction), the photoelectric conversion unit 2C performs processing for converting the image information of the photographic film F into a digital signal along the main scanning direction, and thus converting it into a digital signal The captured image data is transferred to the processing device 4 and stored in the processing device 4.

  The processing device 4 includes a GUI (Graphical User Interface) type interface realized by operating the keyboard 5 and the mouse 6 functioning as a pointing device in accordance with information displayed on the display 3, and further, as described above, the film The image data captured by the scanner 2 or the image data captured via the media drive 7 is stored in the semiconductor memory or hard disk (see FIG. 2) built in the processing device 4 and stored in this way. Software (which will be described in detail later) that performs necessary processing on the processed image data is installed in the processing device 4.

  When the image data is printed on a print medium such as photographic paper, the processing device 4 displays the color tone or the like when the image data is printed on the print medium on the display 3 and needs to be corrected based on this. In some cases, correction processing is performed, and image data (corrected image data) is transmitted to the printing apparatus B (see FIG. 2) by inputting order information such as the print size and the number of prints after the correction processing. Thus, it functions to realize the printing process.

  As shown in FIG. 2, the outline of the control system of the processing device 4 can be shown. That is, a microprocessor (CPU) for processing information is provided, and the media drive 7 for accessing information via the data bus to the microprocessor (CPU), a RAM / ROM composed of semiconductor memory, and data storage And a control interface 11, an operation system 12 composed of a program (software), an image correction unit 13, a chromatic aberration correction unit 14, an order processing unit 15, and a display unit 16. A signal system for inputting signals from the film scanner 2, the keyboard 5, and the mouse 6 to the apparatus 4 is formed. The operation system 12, the image correction means 13, the chromatic aberration correction means 14, the order processing means 15, and the display unit 16 may be configured by a combination of hardware and software, or may be configured only by hardware. Is possible.

  As shown in the figure, the semiconductor memory RAM is formed with a work area where image data is expanded when image processing is performed, and the hard disk HD is formed with an image data storage area for storing image data. Functions as a multi-display means. The multi-display means includes a designation step for designating a plurality of locations on the image of the image data to be processed during the processing by the chromatic aberration correction means 14, an enlargement step for enlarging the designated area, and thus enlargement. The display step of displaying the image data thus displayed on the display 3 is executed. When such processing is performed, the image data to be processed is expanded in the work area of the semiconductor memory RAM, and a process of enlarging and displaying a plurality of designated areas in the expanded image data. The image data for enlargement display is stored in this work area, and the image data set as the processing target and the image data for enlargement display are transferred to the VRAM. The image data and the image data for enlarged display are displayed on the display 3 (this processing form will be described later).

  [Print Processing] In this processing device 4, the image data acquired by the film scanner 2 or the image data acquired from the media drive 7 is attached with index information that can identify the order, and the image data of the hard disk HD. When printing from these image data stored in the storage area, by specifying the order, the operation system 12 causes the image data of the specified order based on the index information to be stored in the semiconductor memory RAM. Further, the operation system 12 further simulates the color tone, contrast, and the like when printed on the print medium based on the image data thus developed and the print conditions, and the thumbnail format image. Generate data (source image) Image data of the thumbnail format (source image) The display unit 16 displays on the display 3 as a pre-judge screen 21 shown in FIG. In the present embodiment, the image data for print processing that has been converted from the work area of the hard disk HD to the number of pixels corresponding to the print size from the work area of the semiconductor memory RAM should be the source image. However, in the present embodiment, the image data of the number of pixels corresponding to the print size is reflected, and the visually recognizable thumbnail image data is defined as the source image.

The pre-judge screen 21 is formed with a thumbnail display area 21A for listing and displaying a plurality of thumbnail-format image data. A print number display section 22 is formed in this screen, and the thumbnail-format image data is scrolled. A scroll bar 23 is formed, and a “clear” switch 24 for setting the number of prints to “0” and an “OK” switch 25 for realizing printing are formed. In addition, a numerical value “1” is displayed as an initial value on the print number display portion 22, and an arbitrary numerical value (number of prints) can be input to the print number display portion 22 by operating the keyboard 5 or the mouse 6. Is possible. It should be noted that all the numerical values can be set to “0” by operating the “clear” switch 24.
If there is no inconvenience in the color tone, contrast, etc. of the image data displayed in the thumbnail display area 21A, the number of prints displayed in the print number display part 22 below the respective image data is confirmed, and then “ By operating the “OK” switch 25, the order processing means 15 executes a process of transmitting the image data and the order data to the printing apparatus B, thereby realizing the printing process. When the switch displayed on the display 3 is operated, the switch is selected by the cursor by operating the cursor key of the mouse 6 or the keyboard 5, and the switch of the mouse 6 is clicked, or a specific key on the keyboard 5 is selected. The operation mode is to operate the keys.

  Further, when it is necessary to correct the image data displayed on the pre-judge screen 21, the “correction” switch 26 is operated at the lower part of the thumbnail display area 21A. When the “correction” switch 26 is operated, a correction dialog box 27 is displayed. By operating the slide switches displayed in the dialog box 27, the image correction means 13 performs color balance and , Hue, Saturation, Brightness, Brightness, and Contrast are corrected, and this correction status is reflected on the pre-judge screen, so that the correction result can be corrected visually and corrected. The process is determined by operating the “OK” switch 28.

  The dialog box 27 displays a “distortion” switch 29 and a “chromatic aberration of magnification” switch 30 as options for image data correction processing. The “distortion” switch 29 realizes processing for correcting image data distorted into a tall shape or a pincushion shape due to the characteristics of the lens of the camera that captured the image data (the processing form is not described in detail). ). The “magnification chromatic aberration” switch 30 realizes correction of chromatic aberration that appears prominently in the peripheral portion of the image data due to the characteristics of the lens of the camera that captured the image data.

  For example, this chromatic aberration of magnification is understood as a phenomenon in which R (red) or B (blue) data out of pixels that should be white in image data is displaced in a direction away from the center of the image data. Is possible. For this reason, when the “magnification chromatic aberration” switch 30 is operated, the data displaced as described above is specified based on the correction parameter, shifted to the original pixel position, and the necessary area. The processing form is set so as to execute the process of interpolating.

  An outline of the processing mode when the “magnification chromatic aberration” switch 30 is operated can be shown as a flowchart in FIG. 3. In other words, when the “chromatic aberration of magnification” switch 30 is operated, a dialog box 31 for correcting the lateral chromatic aberration is displayed as shown in FIG. 6, and the enlargement is performed in a plurality of enlarged display areas 31A on the screen of the dialog box 31. The image data is displayed as a list, and the enlargement target area D is displayed in a form that is divided into lines with respect to the thumbnail display area 21A of the pre-judge screen 21. When performing this display process, the display unit 16 acquires the source image data, acquires the default values of the locate data and the enlargement ratio, and executes the enlarged image display process (# 01, # 02). , # 100 step).

  The enlarged image display process (step # 100) is set in the form of a subroutine as shown in the flowchart of FIG. That is, the enlargement target area D that is a frame-like image is displayed on the thumbnail-format image data based on the locate data, and then the number of the enlarged display areas 31A and the enlarged display area 31A are displayed based on the locate data. Are set (steps # 101 and # 102), and a plurality of reference positions based on the locate data among the image data for print processing already developed in the work area of the semiconductor memory RAM as a processing target. Is specified, image data corresponding to the specified area is generated as image data for enlarged display, and this enlarged display image data is displayed in the enlarged display area 31A (#). 103- # 105 steps).

  In steps # 103, # 104, and # 105, in the image processing method of the present invention, a designation step for designating a plurality of locations of the image data to be processed, and generating image data for enlarged display of the image data at the designated locations. And the step of displaying the enlarged display image thus generated on the display. These steps # 103, # 104, and # 105 are processing targets in the image processing program of the present invention. The function of designating a plurality of locations of the image data, the function of enlarging the image data of the designated locations, and the function of displaying the enlarged image data of the plurality of locations on the display.

  For example, the locate data is given as coordinates P (P1 to P9) set in the image data as shown in FIG. 7, and the enlargement ratio is given as a numerical value. Accordingly, when enlarging the image data, as described above, a plurality of coordinates P are set on the image of the image data stored as a processing target in the work area of the semiconductor memory RAM, and the coordinates P are used as a reference. This is realized by performing an enlarged display process based on the enlargement ratio, storing the processing result in the work area of the semiconductor memory RAM, and transferring the enlarged image formed in the storage area of the VRAM as the enlarged display area 31A. When displaying an enlarged image in this way, the positional relationship corresponding to the enlargement target area D displayed on the image data, that is, the enlarged image of the enlargement target area D in the upper left corner is displayed in the upper left of the dialog box 31. By arranging each enlarged image in a positional relationship corresponding to the enlargement target area D, such as arranging in the corner, the positional relationship between the enlarged image and the enlargement target area D can be easily understood.

  Further, the default value of the coordinate P includes a position farthest from the center position on the image of the image data. The enlargement means that a plurality of pixels of the image data is converted into a size that can be separated and identified on the display 3, and is expanded in the work area of the semiconductor memory RAM as an enlargement process. The processing mode may be such that the image data for print processing is extracted and transferred directly to the VRAM.

  The magnification chromatic aberration correction dialog box 31 displays a correction parameter input section 32, an enlargement ratio adjustment section 33 for adjusting a zoom-type enlargement ratio, an option switch 34, an “OK” switch 35, and the like.

  Then, by inputting a preset correction parameter from the drop-down list to the correction parameter input unit 32, the required magnification chromatic aberration correction is realized (steps # 03 and # 04). Further, the magnification chromatic aberration correction process is realized by the chromatic aberration correction means 14, and this correction parameter should originally be set by specifying the type of lens for each manufacturer. Correction parameters that can correct chromatic aberration of magnification of image data captured by a plurality of lenses are registered in advance.

  The enlargement ratio adjustment unit 33 can adjust the enlargement ratio of the image data displayed in the enlargement display area 31A by operating a slide switch in the screen. Thus, the thumbnail display area 21A can be adjusted along with the adjustment of the enlargement ratio. The size of the enlargement target area D displayed on the screen also changes (steps # 05 and # 06). Further, when the size of the enlargement target area D is changed, the size of the frame-like image indicating the enlargement target area D is changed with reference to the corresponding coordinates P.

  That is, by arbitrarily setting the enlargement ratio, the enlargement ratio of the image data displayed in the enlarged display area 31A can be arbitrarily adjusted by the above-described enlarged image display process (step # 100), and the enlargement target is associated with this adjustment. The size of area D will change.

  The display mode means increasing / decreasing the number of enlargement target areas D or moving the enlargement target area. When the display mode is changed in this way, locate data is acquired. Thus, the display mode can be changed (# 07, # 08 steps) by the enlarged image display process (# 100 steps).

  As a specific setting mode for changing the display mode, as shown in FIG. 8, the cursor is moved to the enlargement target area D formed in the thumbnail display area 21A of the pre-judge screen 21 by the operation of the mouse 6. The confirmation message shown in the figure is displayed by an operation such as clicking the left switch of the mouse 6 and the like, and the “Yes” switch is operated, whereby the locate data corresponding to the enlargement target area D where the cursor matches is displayed. As a result, the enlarged display area D and the corresponding image in the enlarged display area 31A are deleted. As shown in FIG. 9, the cursor is matched with the thumbnail display area 21A of the pre-judge screen 21, and the mouse 6 The confirmation message shown in the figure is displayed by operations such as clicking the left switch, and the “Yes” switch is operated. The Rukoto, the coordinates of the corresponding position is generated as B Kate data, as a result, has an enlarged display area D, and can newly create an image of a corresponding enlargement area 31A. In this way, when the number of enlarged display areas 31A is increased or decreased, the processing mode is set so that the enlarged display area 31A displayed in the dialog box 31 for correcting the chromatic aberration of magnification is set to an appropriate layout.

  Although not shown in the drawing, the cursor is made to coincide with the enlargement target area D formed in the thumbnail display area 21A, and the cursor is moved in a state where the left button is pressed, so that the enlargement is performed by dragging. It is also possible to set the processing mode so as to change the target area D to an arbitrary position on the thumbnail display area.

  When the option switch 34 is operated, an option setting dialog box 41 shown in FIG. 6 is displayed. In this dialog box 41, a correction parameter setting unit 42 for setting a default value displayed in the correction parameter input unit 32, and an enlargement factor for setting a default value of an enlargement factor of image data displayed in the enlarged display region 31A. And a display number setting unit 44 for setting a default value of the display number of the thumbnail display area 21A is formed, and after these settings are made, the lower “OK” switch 45 is operated. Will save the default value.

  After the necessary processing is performed as described above, the correction processing is completed by operating the “OK” switch 35 displayed in the dialog box 31 for correcting the chromatic aberration of magnification (step # 09).

  As described above, according to the present invention, when correcting the chromatic aberration of magnification, the image data displayed in the thumbnail format on the pre-judge screen 21 is used as a source image, and a plurality of enlargement targets set on the image of the source image are used. Since the area D is displayed in a corresponding positional relationship with respect to the enlarged display area 31A of the dialog box 31, it is possible to accurately grasp the state of chromatic aberration in pixel units and reasonably determine the result of the correction process. Yes. In particular, since the lateral chromatic aberration appears more conspicuously as the position is farther from the center position on the image of the image data, an error-free judgment can be made by setting the enlargement target area D from the center position on the source image. To make things.

  Further, according to the present invention, it is possible to change the number of areas designated as the enlargement target, arbitrarily change the position of the area to be enlarged, and arbitrarily change the enlargement ratio of the image data for enlargement display. Therefore, the state of aberration and the correction result are easily grasped based on the image enlarged at the required magnification.
