Description

  The invention described in this specification relates to a technique for displaying a work screen suitable for use in checking the correction strength. Note that the invention described in this specification has aspects as an electronic device, a printing apparatus, a work screen display method, a program, and a storage medium.

  With the spread of digital cameras, opportunities for users to print out captured images are increasing. For example, there are increasing opportunities for users to operate a DPE (Development Printing Enlargement), a print kiosk, or their own printing system to print out a photographed image.

In such a printing system, various conveniences are provided so that the user can easily and surely perform printing without using a specialized operator.
For example, when converting image data photographed with a digital camera or the like into print data, an optimum correction process is automatically applied.

  For example, at the time of color conversion from an RBG image to a CMYK image, a correction process for improving the appearance is automatically executed. This is because the RGB image is not simply a color-converted CMYK image, resulting in an image that does not look good.

  By the way, the correction strength used in correction processing is an average value that is statistically preferred by the largest number of users so that it can handle a wide range of users and a wide variety of image prints while avoiding complicated settings. Is usually applied.

  Strictly speaking, however, the appropriate value of the correction strength differs for each user and also differs depending on the type of image data. As a result, only a safe print result can be obtained by applying a statistically determined correction strength to all image data.

  On the other hand, various correction functions and setting methods are prepared in existing image processing software. However, these correction functions and setting methods are too flexible for general users. For this reason, the results are inconvenient for general users who are unfamiliar with image processing.

  Actually, when a general user uses existing image processing software, it takes a long time to reach a target correction result, or even reaching a target correction result is difficult.

FIG. 1 shows an example of a screen on image formation described in FIG. 3 of Japanese Patent Application Laid-Open No. 2005-267485. This screen is for inputting the user's evaluation for the print result for each correction parameter. When an evaluation other than OK is input on this work screen, the corresponding correction parameter is adjusted at the next printing.

  However, this method has a problem that it does not know how the evaluation result is reflected in the image correction until the user gets used to using the printer. That is, the user cannot predict the correction result in advance, and there is a problem in usability.

FIG. 2 shows a screen example described in FIG. 7 of Patent Document 2. This screen is used to specify the correction amount of the correction parameter while confirming the image displayed on the image display unit before printing the image. By using this screen, an image according to preference can be printed.

  Incidentally, in the case of this method, when any one of brightness, hue, contrast, and sharpness correction is designated, images with different degrees of the processing are displayed on the left and right of the original image.

JP, 2001-350467, A FIG. 3 shows the example of a screen explained in Drawing 2 of patent documents 3. In FIG. In this screen, a small screen for image quality adjustment such as density correction, color correction, sharpness, and soft focus is displayed in the vicinity with the entire target image displayed in a large size.

All of the three methods described above require that the correction effect on the entire screen be confirmed using a partial display on a display that has a resolution much lower than that of an actual print.
For this reason, it is difficult to correct fine portions of an image, particularly noise correction and sharpness correction, and it is necessary to add a display screen enlargement function. However, if the screen is enlarged, only a part of the image can be seen.

  As a result, the user needs to move the center of the enlarged image to the partial image to be confirmed. In other words, prior confirmation of the correction result is very difficult and complicated for general users.

  Therefore, the inventor proposes a work screen display technique that enables easy setting of correction strength suitable for the user's preference and the contents of various image data.

(A) Technology 1
As one of the proposed techniques, a first feature region that includes the most image components targeted by the selected correction function and a second feature region that includes the least image components targeted by the selected correction function Processing for automatically extracting from the correction target image, an overall view of the target image corrected by the selected correction function, an enlarged view of the corrected image for the first feature region, and a second feature region A work screen display technique is proposed that includes processing for displaying an enlarged view of a corrected image side by side on a display screen.

(B) Technology 2
As one of the proposed technologies, the first feature region most suitable for confirming the correction effect of the selected correction function in the target image, and the confirmation of the correction effect of the correction function that obtains a correction effect contrary to the correction function Processing for automatically extracting the second feature region most suitable for the correction target image, an overall view of the target image corrected by the selected correction function, and the corrected image of the first feature region A work screen display technique is proposed that includes processing for displaying an enlarged view and an enlarged view of a corrected image for the second feature region side by side on the display screen.

  If this display technique is used, it is possible to confirm the effect of the correction in a state in which the two feature regions in which the difference in the correction effect is the largest among the target images are enlarged.

  Therefore, even on a display having a resolution much lower than that of an actual print, the user can easily and reliably confirm the detailed correction effect corresponding to the current correction strength.

  Moreover, it is possible to confirm an image of a portion where the correction effect works best and a portion where the correction effect works weakly or a portion which deteriorates reciprocally in one screen. For this reason, the balance of the correction strength can be easily and easily adjusted.

Hereinafter, a case where the work screen display technique proposed by the inventor is installed in a printer will be described.
In addition, the well-known or well-known technique of the said technical field is applied to the part which is not illustrated or described in particular in this specification.
Moreover, the form example demonstrated below is one form example of invention, Comprising: It is not limited to these.

(A) Configuration Example (A-1) Configuration of Print System (a) Overall Configuration FIG. 4 shows a functional block configuration of the print system 1 according to the configuration example.
The print system 1 shown in FIG. 4 can be classified mainly into four functional blocks: an image processing module 3, a touch panel display 5, a hard disk drive 7, and an image forming unit 9.

(B) Detailed Configuration FIG. 5 shows a detailed configuration of the print system 1.

(I) Image Processing Module The image processing module 3 includes a control unit 31, an interface unit 33, a JPEG decompression unit 35, an RGB / size conversion unit 37, and an image processing unit 39. The touch panel display 5 includes a display unit 51 and an input unit 53.

The control unit 31 is configured by a computer system. That is, the control unit 31 includes a CPU (Central Processing Unit) 311 and a RAM (Random
Access Memory) 313 and ROM (Read Only Memory) 315.

  The CPU 311 controls movements related to image processing and printing processing according to a program stored in the ROM 315. A part of the program here corresponds to a display program for a work screen for adjusting correction intensity. The CPU 311 operates as a “feature area extraction unit” and a “work screen generation unit” in the claims. Details of the program will be described later. The RAM 313 is a temporary storage area for programs, image data, and the like.

  The interface unit 33 is a circuit device used for transmitting / receiving various data to / from an external device. For example, it includes an Ethernet (registered trademark) interface, a USB interface, a wireless USB interface, an IrDA interface, an infrared remote control interface, a Bluetooth interface, and the like.

  The interface unit 33 is configured by a card reader that reads image data from an external storage medium. For example, it is composed of a card reader corresponding to various storage media such as a memory stick, smart media, PC card, compact flash (registered trademark), and SD. By installing this circuit device, direct printing becomes possible.

  The JPEG decompression unit 35 is a processing device that executes decompression processing when the image data fetched from the interface unit 33 is compressed and encoded. By this decompression process, the image data is converted into luminance data Y and color difference data Cb and Cr. The converted luminance data Y and color difference data Cb and Cr are output to the RGB / size converter 37.

  The RGB / size conversion unit 37 is a processing device that applies RGB conversion processing and size conversion processing to uncompressed image data taken in from the interface unit 33 and image data decompressed by the JPEG decompression unit 35. Note that R (red), G (green), and B (blue) primary color data obtained by the RGB conversion process are stored in the RAM 313.

  The image processing unit 39 performs a process of converting the primary color data read from the RAM into complementary color data (Y (yellow), M (magenta), C (cyan), K (black)) and a process of gamma conversion. .

  The primary color data to be processed by the image processing unit 39 is primary color data after execution of correction processing based on the correction intensity set through the work screen (user interface) proposed by the inventor.

(Ii) Touch Panel Display The touch panel display 5 includes a display unit 51 and an input unit 53. In the case of this embodiment, the display unit 51 is a liquid crystal display, and is used to display image data, operation information, management information, and other information.

  The input unit 53 is an input device for receiving user operation information. In the case of this embodiment, a touch panel is used. Accordingly, the position touched by the finger is transmitted to the CPU 311 through the touch panel.

(Iii) Hard Disk Drive The hard disk drive 7 is a large-capacity storage area used for storing image data. The hard disk drive 7 stores image data before correction, image data after correction, individual correction values, and the like.

  In this embodiment, the hard disk drive 7 built in the print system 1 is used as a storage area for image data. However, a portable external storage memory owned by the user or an external device connected using network technology is used. A storage memory may be used.

(Iv) Image Forming Unit The image forming unit 9 records an image on a recording medium (for example, paper) based on the complementary color data input from the image processing unit 39. In the case of this embodiment, the image forming unit 9 is composed of a print head and a print engine corresponding to the sublimation printing method, and the recording method may be other recording methods.

(A-2) Work Screen Example (a) Basic Layout FIG. 6 shows a basic layout of a work screen proposed by the inventor. The work screen shown in FIG. 6 is displayed when the correction strength is set.
On the work screen 61, a correction target image display area 63, correction effect confirmation areas 65 and 67, correction intensity adjustment buttons 69 and 71, and a preview display operation button 73 are laid out on the same screen.

  The correction target image display area 63 is an area for displaying the entire image to be corrected. By confirming this display area, the user can confirm the effect of correction on the entire screen.

  The correction effect confirmation area 65 is an area for enlarging and displaying an image block (feature area) that includes the most image components on which the selected correction function operates. In the case of this embodiment, the image block uses an image size obtained by dividing the entire correction target screen into 16 parts. In the correction effect confirmation area 65, an image obtained by enlarging the original image several times is displayed. For example, an image magnified 4 times (vertically 2 ×× 2 ×) is displayed.

  Note that the computer 311 automatically executes extraction of an image block including the most image components on which the selected correction function operates. Since there are various methods for this kind of extraction technique, details are omitted. Incidentally, when the correction function is noise cancellation, an image block having the largest noise component is extracted. When the correction function is sharpness, an image block having the largest edge component is extracted.

  The correction effect confirmation area 67 is an area for enlarging and displaying an image block (feature area) having the smallest image component on which the selected correction function operates. Also in this case, the correction effect confirmation area 67 displays an image obtained by enlarging an image corresponding to 16 divisions of the entire original image several times. For example, an image magnified 4 times (vertically 2 ×× 2 ×) is displayed.

  Note that the computer 311 also automatically extracts an image block having the smallest image component on which the selected correction function operates. For example, when the correction function is noise cancellation, an image block with the smallest noise component or an image block with the largest edge component is extracted. When the correction function is sharpness, an image block having the smallest edge component or an image block having the largest noise component is extracted.

  The correction intensity adjustment buttons 69 and 71 are operators for adjusting the correction intensity of the corresponding correction effect confirmation area. When the effect of the selected correction function is in conflict with the effect of other correction functions, the controls corresponding to the two opposite correction functions are displayed separately. However, if there is no conflict between the effect of the selected correction function and the effect of other correction functions, only one correction intensity adjustment button is displayed.

  The preview display operation button 73 is an operator prepared for comparing images before and after setting the correction strength. For example, when the preview display is on, the corrected image is displayed in the correction target image display area 63 and the correction effect confirmation areas 65 and 67. For example, when the preview display is off, the image before correction is displayed in the correction target image display area 63 and the correction effect confirmation areas 65 and 67.

(B) Specific Example Hereinafter, a specific example of the work screen will be described.
FIG. 7 shows an example of the correction target image. The correction target image 81 shown in FIG. 7 is a snap photo in which the face of the person 83 is greatly shown in the center of the screen.

That is, the blue sky 85 in which noise is easily visible is located in the background of the person 83, and a face with a fine outline such as the eyes and nose is located in the center of the screen.
FIG. 8 shows an example of a display screen when the image shown in FIG. 7 is selected as a correction target. The basic display layout is as described in FIG.

FIG. 8 shows a state where a correction target image and noise correction are selected by a touch operation on a subject or a menu screen.
The contents of the partial images displayed in the correction effect confirmation areas 65 and 67 are automatically extracted by the CPU 311 based on the data distribution of the primary color data corresponding to the correction target image 81. Therefore, a part of the blue sky (image block) that needs the most noise correction is displayed in the correction effect confirmation area 65 surrounded by the outer frame 91.

  On the other hand, in the correction effect confirmation area 67, the peripheral portion (image block) of the human eye having the least noise component (that is, having the largest edge component) on which noise correction is applied is surrounded by an outer frame 93 and displayed. .

  In general, a relationship in which correction effects are contradictory is recognized between noise correction and sharpness correction. For example, it is recognized that the sharpness is weakened when the intensity of noise correction is increased, and the noise becomes conspicuous when the intensity of sharpness is increased. For this reason, it is considered difficult to determine the two correction strengths in a balanced manner.

  However, on this work screen 61, enlarged views of two characteristic areas in which conflicting correction effects appear are displayed side by side on the screen, so that the effect of the selected correction strength can be easily confirmed. Accordingly, it is possible to set a correction intensity optimum for the user's preference and image content while checking the balance of correction effects.

In the case of FIG. 8, the outer frames 91 and 93 of the extraction area and the correction effect confirmation areas 65 and 67 are clarified so that the correspondence between the automatically extracted image block and the correction effect confirmation areas 65 and 67 becomes clear. Line segments 95 and 97 that connect the two are displayed superimposed on the screen.
For this reason, even if the image portion displayed in the correction effect confirmation areas 65 and 67 is automatically extracted, the user can easily confirm the positional relationship in the correction target image.

  Note that the correction strength adjustment buttons 69 and 71 associated with the correction effect confirmation areas 65 and 67 can be operated independently, and an image to which a correction effect corresponding to the operation amount is added is to be corrected. This is reflected in the display contents of the image display area 63 and the correction effect confirmation areas 65 and 67.

  Note that when determining the correction amount, comparing the images before and after changing the correction intensity is effective in improving work efficiency. In this case, the preview display operation button 73 may be operated.

  Note that the user can print the correction target image prior to setting the correction strength, and perform the setting while confirming the print result in advance. It is also possible to print and confirm the correction target image after setting the correction strength.

It is also possible to check the difference between the image displayed on the display and the image printed by the image forming unit 9 in advance, and strictly set the correction intensity.
The image displayed in the correction effect confirmation areas 63 and 65 can also be selected by the user himself. In general, it is sufficient to check an image that is automatically extracted, but it may be different from the region that the user is paying attention to because it is automatic.

  Therefore, in this case, the correction effect can be confirmed by moving both or one of the outer frames 91 and 93 displayed in the correction target image display area 63 to a desired position.

(A-3) Flowchart FIG. 9 shows a flowchart example of a program related to the display of the above-described work screen.
First, the program automatically extracts a feature region that requires noise correction and a feature region that requires sharpness correction, and displays an enlarged image corresponding to each feature region (S1).

  Thereafter, the program executes noise correction and sharpness correction based on the correction intensity designated through the work screen (S2, S3). These correction processes are performed on the entire correction target image.

  Thereafter, a determination process for inquiring the user whether or not to confirm the setting of the correction strength is executed (S4). Until the correction strength determination operation is detected, the correction operation with the set correction strength is repeated.

On the other hand, when the operation for determining the correction strength is detected, the program executes a determination process for confirming whether or not to save the image data reflecting the current correction strength (S5).
If a negative result is obtained in this determination process, the program ends the process.

  On the other hand, when a correction result is obtained in this determination process, the image data before correction, the image data after correction, and the set correction intensity value are stored in a storage medium in a state associated with the user name, setting date, and other additional information. (S6). By this saving, the setting value saved from the next time can be read and used.

(A-4) Effect In the case of the above-described work screen, a feature region in which a correction effect that is the weakest or opposite to the feature region that has the strongest correction effect is automatically displayed in the correction target screen during the correction intensity setting operation. The partial image corresponding to the extracted area can be enlarged and displayed.

  For this reason, the user can determine an appropriate correction strength while finely comparing the correction effects of the two characteristic regions having the largest or opposite difference in correction effects in the correction target image as an enlarged view. At this time, the user does not need to perform any operation such as scrolling or searching for the target area, and can concentrate on the adjustment of the correction intensity, so that the correction intensity can be set easily and efficiently.

  In the work screen described in the embodiment, the positional relationship between the image extracted as the feature region and the correction target image can be displayed in association with a frame display, a thick line, etc., so that the partial correction effect and the entire image correction effect can be displayed. Can be confirmed at the same time.

Further, since the preview display can be switched as shown in the embodiment, the difference in image quality before and after the correction according to the set correction intensity can be easily compared.
Needless to say, the work screen shown in the embodiment can be used not only before printing but also for adjusting the correction strength after printing. If the correction strength is adjusted by comparison with the actual print result, the correction strength can be set more strictly.

  In the case of this embodiment, the set correction intensity information can be stored for each user and for each image. Therefore, if the set values are read out even at different image correction opportunities, it is possible to easily realize a correction result optimal for the user's preference and the type of image.

(B) Other embodiment examples (B-1) Other correction examples In the case of the above-described embodiment examples, a case has been described in which a correction function having a relationship in which the correction effects on the image are contradictory is selected.

  However, the present invention can also be applied to the case where the correction strength of a correction function that does not necessarily have a conflicting effect with other correction functions, such as color correction and luminance correction, is adjusted.

(B-2) Application Device Example The work screen creation or display function described above can be installed in electronic devices other than the printing system. Further, the display purpose of the work screen may be not only for printing but also for the purpose of screen display.
