Description

  The present invention relates to a print image data processing apparatus, a print image data processing method, and print image data for obtaining a print result suitable for the type and size of a print sheet when printing an image taken with a digital camera or the like. It relates to a processing program.

  In recent years, with the increase in the speed of personal computers, the acceleration of memory capacity, and the widespread use of digital cameras, film scanners, printers, and the like, the opportunity to handle digital image data on a personal computer has increased. In addition, users can easily print using digital cameras and printers.

  The general printing size with silver salt film was large in L size and postcard size. However, users can easily print using digital cameras and printers, so in addition to L size and postcard size. Thus, A4 size and A3 size printing, and even borderless printing can be easily performed (see Patent Document 1).

The user reads digital image data captured by a digital camera or the like on a personal computer and executes image correction processing such as contrast correction and saturation correction while displaying the image data on a monitor using an application or the like, or After performing trimming processing and editing the image data to the user's preference, the output is obtained from the printer. Also, connect the digital camera directly to the printer without using a personal computer, and display the image data on the liquid crystal display of the digital camera while editing the image on the digital camera in the same way as above to optimize the user's preference. Output can be obtained. Further, the printer reads image data directly from a storage medium such as a memory card, and displays the image data on a liquid crystal display unit provided in the printer, and executes image editing similar to the above on the printer, so that the user's favorite optimum Output can be obtained.
Japanese Patent Laid-Open No. 2004-054898

  In a system including a current digital camera and a personal computer, the number of pixels of image data, the resolution and the number of pixels necessary for monitor display, and the resolution and the number of pixels necessary for printing differ greatly as follows.

  Imaging devices such as CCDs and CMOSs used in digital cameras have 1 million pixels to 10 million pixels or more, and captured image data also has 1 million pixels to 10 million pixels or more.

  In the monitor of a personal computer, as a standard of resolution and the number of pixels, XGA (resolution: 1,024 × 768, number of pixels: 786,432), SXGA (resolution: 1,280 × 1,024, number of pixels: 1,310,720) ), UXGA (resolution: 1,600 × 1,200, number of pixels: 1,920,000) is generally used, and when displaying image data on a monitor, only about 2 million pixels are used at the maximum. . Therefore, normally, there are few full-screen displays on the monitor, and a partial display is made on the monitor in the application. For this reason, the number of pixels required for display is further reduced.

  Since the number of pixels of the liquid crystal display unit included in the digital camera or printer is about 100,000 to 300,000 pixels, when displaying image data of 1 million pixels to 10 million pixels or more on the liquid crystal display unit, the number of pixels of the image data is set. Rather than using all, image data is often sampled and displayed according to the resolution of the liquid crystal display.

  On the other hand, since it is said that at least a resolution of 200 to 300 DPI or more is necessary to print image data neatly with a printer, the resolution necessary to print neatly on postcard paper (148 mm × 100 mm) is 900. X660 (200 DPI) to 1400 x 1000 (300 DPI) or higher, and the resolution required to print beautifully on A4 size (297 mm x 210 mm) paper is 2400 x 1680 (200 DPI) to 3560 x 2520 (300 DPI) or higher It becomes. In order to obtain a beautiful print, the L size requires 2 million pixels or more, and the A4 size requires 4 million pixels or more, which requires a data amount larger than the number of pixels necessary for monitor display.

  As described above, the number of pixels of the image data, the resolution and the number of pixels necessary for the monitor display, and the resolution and the number of pixels necessary for the printing are greatly different, but the user usually displays the image data on the monitor while displaying the image data. Since image editing such as correction processing and trimming processing is executed, there is no need to be aware of the resolution of image data necessary for neat printing.

  For this reason, when the trimming process is executed on the monitor, the image data looks fine on the monitor, so the image is often trimmed to a resolution lower than that required for printing, and the print result with the image quality expected by the user may not be obtained. .

  Further, JPEG, which is a format of image data stored in a digital camera, compresses image data by irreversible compression. If the compression rate is increased, the file size is reduced, but the image quality of the image data is deteriorated. However, when image data with a large number of pixels, for example, image data with 10 million pixels is compressed at a very high compression rate, the image quality deteriorates considerably, but when displayed on a monitor, only about 1 million pixels are sampled and used. Therefore, there is a problem that it is difficult for the user to notice deterioration in image quality. On the other hand, when image data compressed with JPEG or the like is printed on paper, there is a problem that image quality deterioration caused by a high compression rate appears in the print result.

  In other words, there is a problem that the user cannot obtain the print result with the image quality expected by the user even though the user is satisfied with the monitor display.

  FIG. 2 is a block diagram showing functions of the print image data processing apparatus of FIG. The CPU 103 mainly executes each function of the print image data processing apparatus.

  In the figure, 201 is target image data, 202 is an image data input unit for reading the image data 201 from a memory stored in the digital camera 107 or a recording medium such as the HD 105 of the host computer 100, and 203 is a printer. A print condition setting unit for the user to set the print paper type, print paper size, print quality, print image size, and the like for printing at 108, and 204 analyzes the image size and compression rate of the image data 201. An image data analysis unit 205, a trimming designation unit 205 for the user to designate a trimming size or a trimming position for the image data 201, 206 is calculated from printing conditions such as a paper size designated by the user in the printing condition setting unit 203.

An operation unit 301 includes an image data display area 302 that displays image data, a trimming area frame 303 that operates and displays a trimming area, a printing condition display area 304 that displays and specifies printing conditions, and a print start button that starts printing. 305 is provided.

  FIG. 3B shows a warning display executed by the trimming size warning unit 207, which prompts the user to change the trimming size or to change the print settings.

  FIG. 4 is a flowchart showing processing executed by the print image data processing apparatus of FIG.

  First, the image data input unit 202 reads the target image data 201 from the HD 105 or the like (step S401), and the image data analysis unit 204 analyzes the image size, compression rate, and the like of the image data (step S402).

  Next, the printing condition setting unit 203 sets printing conditions such as the paper size input via the operation unit displayed on the monitor 106 (step S403), and the trimming designation unit 205 is displayed on the monitor 106. The trimming position, size, and the like of the image data input via the unit are determined (step S404).

  Next, the resolution and image size of the trimming image calculated from the printing resolution and image size calculated from the printing conditions such as the paper size input via the operation unit and the trimming size specified by the trimming specification unit 205 To determine whether the trimmed image has a trimming size suitable for the print quality expected by the user (step S405).

  If the print quality expected by the user cannot be obtained as a result of the determination in step S405, the trimming size warning unit 207 displays a warning regarding the trimming size on the monitor 106, and changes the trimming size or the print settings. To the user (step S406). Thereafter, when changing the trimming size, the process proceeds to step S404, and when changing the printing condition, the process proceeds to step S403.

  As a result of the determination in step S405, if the print quality expected by the user is obtained, the print image creation unit 208 creates print image data (step S407), and finally outputs the print image data created in step S407. (Step S408), and this process is terminated.

  As described above in detail, according to the present embodiment, the print resolution and image size calculated from the printing conditions such as the paper size input via the operation unit, and the trimming designated by the trimming designation unit 205 The resolution and image size of the trimmed image calculated from the size and the like are compared, and it is determined whether or not the trimmed image has a trimming size suitable for the print quality expected by the user, and the print quality expected by the user is obtained. If not, the trimming size warning unit 207 displays a warning regarding the trimming size on the monitor 106 and prompts the user to change the trimming size or the print setting. This can be prevented before printing.

  Next, a second embodiment of the present invention will be described with reference to FIGS.

  The second embodiment of the present invention is different from the first embodiment in that a compression rate warning unit 501 is provided instead of the trimming designation unit 205 and the trimming size warning unit 207.

  The configuration of the print image data processing apparatus according to the second embodiment is the same as that of the print image data processing apparatus according to the first embodiment.

  FIG. 5 is a block diagram showing functions of the print image data processing apparatus according to the second embodiment of the present invention. The CPU 103 mainly executes each function of the print image data processing apparatus.

  The same functions as those of the print image data processing apparatus in FIG. 2 are denoted by the same reference numerals, description thereof is omitted, and only different portions will be described.

  In FIG. 5, a printing condition determination unit 206 includes a compression rate of image data calculated from printing conditions such as a paper size specified by the user in the printing condition setting unit 203 and a compression rate of image data analyzed by the image data analysis unit 205. To determine whether the image data has the print quality expected by the user. The compression rate warning unit 501 notifies the user of a warning when the image data does not have the print quality expected by the user.

  Since there are various methods for analyzing the compression rate of the image data in the image data analysis unit 205, any method may be used. When the compression rate is previously added to the image data as tag data, the compression rate may be read from the tag data. When the image data is JPEG data, the compression rate can be estimated from a table used for compression. It is also possible to analyze the image data and estimate the compression rate from the relationship between the spatial frequency and the image size.

  The printing condition determination unit 206 compares the compression rate calculated from the printing conditions such as the paper size specified by the user with the compression rate of the image data analyzed by the image data analysis unit 205, and the image data has the print quality expected by the user. For example, it is specified that the compression rate of the image data needs to be 50% or less under the printing conditions (L size, photographic paper, and the highest quality). If the rate is 51%, it is determined that the print quality expected by the user is not achieved. When such a determination is made, the compression rate warning unit 501 warns the user and prompts the user to change the print settings. It is assumed that the compression rate of the image data corresponding to the printing conditions is calculated in advance and stored in the HD 105 as a table or the like.

  FIG. 6 is a diagram illustrating an example of an operation unit and a warning display of the print image data processing apparatus.

  In FIG. 6A, reference numeral 601 denotes an example of the operation unit. The operation unit 601 is displayed on the monitor 106 when the CPU 103 activates the application 102 and executes a print instruction. The operation unit 601 includes an image data display area 602 for displaying image data, a print condition display area 604 for displaying and specifying print conditions, and a print start button 605 for starting printing.

  FIG. 6B shows a warning display executed by the compression ratio warning unit 501. This warning display prompts the user to reduce the paper size or the print quality.

  FIG. 7 is a flowchart showing processing executed by the print image data processing apparatus.

  The same steps as those in FIG. 4 are denoted by the same step numbers and the description thereof is omitted.

  In step S403, when the print condition setting unit 203 sets the print condition such as the paper size, the print condition determining unit 206 calculates the compression rate and the image data analysis unit calculated from the print condition such as the paper size specified by the user. The compression rate of the image data analyzed in 205 is compared, and it is determined whether or not the compression rate calculated from the printing conditions is a compression rate suitable for the print quality expected by the user (step S701).

  In step S701, if the compression rate is not suitable for the print quality expected by the user, the compression rate warning unit 501 displays a warning regarding the compression rate of the image data on the monitor 106 to reduce the paper size or print quality. The user is prompted to lower it (step S702). If the printing conditions are to be changed, the process proceeds to step S403.

  If it is determined in step S701 that the compression rate is suitable for the print quality expected by the user, the process proceeds to step S407.

  As described above in detail, according to the present embodiment, the printing condition determination unit 206 calculates the compression rate calculated from the printing conditions such as the paper size specified by the user and the image analyzed by the image data analysis unit 205. Comparing with the data compression rate, it is determined whether the compression rate calculated from the printing conditions is a compression rate suitable for the print quality expected by the user, and compression suitable for the print quality expected by the user If not, the compression rate warning unit 501 displays a warning regarding the compression rate of the image data on the monitor 106 and prompts the user to reduce the paper size or the print quality. It is possible to prevent the deterioration of the print image quality due to the rate before printing.

  In the first and second embodiments, if the trimming size or the compression rate of the image data is not suitable for the print quality expected under the specified printing conditions, a warning is given to the user, the trimming change or the printing conditions However, if the user desires to print even with poor print quality, it is possible to create print image data according to the printing conditions. In such a case, the print condition setting unit 203 transmits a forced printing instruction to the print image creating unit 208.

  In the first and second embodiments, it has been described that the processing of FIGS. 4 and 7 is executed by the host computer 100. However, the digital camera 107 or the printer 108 has functions equivalent to those of the host computer 100. The digital camera 107 or the printer 108 can perform the same processing. For example, when the printer 107 has a function equivalent to that of the host computer 100, the image data 201 is read from a reading unit such as a card reader provided in the printer 107 via a memory card, or the digital camera 108 and the printer 107 are connected. It is also possible to read out from a memory card held by the digital camera 108 or a built-in memory by connecting with a wired cable, infrared communication means, or wireless communication means.
