[0002]
[Prior art]
In recent years, with the spread of digital cameras and the like, there is a printing apparatus having a so-called direct printing function for directly reading out and printing image data stored in a storage medium. In addition, this type of printing apparatus has a function that can print a list of a plurality of images on a single sheet of paper when printing image data directly from a storage medium, that is, a so-called thumbnail-format index print function. There is also. According to the index print function, a large number of reduced images are printed on a single sheet based on a matrix expression format (list print pattern) in which the number of rows and columns is defined in advance, and the user sees the print result and selects the user's favorite It is possible to select and print an image.
[0003]
On the other hand, recent facsimile machines tend to be multi-functional in addition to the main communication function as well as the printer function and scanner function so that they can operate independently.

[0005]
For example, when the main scanning direction of the printing operation by the ink jet method is the horizontal direction of the paper transported in the vertical direction, and the reduced image is printed in an m × n matrix representation format along each vertical and horizontal direction, the number of horizontal image arrangements If n image data cannot be developed using the free space of the memory according to n, n image data cannot be processed in parallel according to the printing operation along the main scanning direction. A list of reduced images could not be printed. This depends on not only the free space of the memory but also the data size depending on the resolution of the image data itself, and there are cases where the list can be printed at a low resolution but cannot be printed at a high resolution.
[0006]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
[0024]
FIG. 1 is a block diagram showing a configuration of a facsimile apparatus as an embodiment of a printing apparatus according to the present invention. As shown in this figure, the facsimile apparatus A according to the present invention includes a CPU 10, an NCU 11, a RAM 12, a modem 13, a ROM 14, an EEPROM 15, a gate array 16, a codec 17, a DMAC 18, a reading unit 21, a printing unit 22, an operation unit 23, The display unit 24, the slot unit 25, the external connection unit 26, and the like are schematically configured. The CPU 10, NCU 11, RAM 12, modem 13, ROM 14, EEPROM 15, gate array 16, codec 17, and DMAC 18 are connected to each other by a bus line 27. The bus line 27 includes an address bus, a data bus, and a control signal line. A reading unit 21, a printing unit 22, an operation unit 23, a display unit 24, a slot unit 25, and an external connection unit 26 are connected to the gate array 16. A public telephone line 28 is connected to the NCU 11. A personal computer B is connected to the external connection unit 26.
[0025]
The CPU 10 controls the operation of the entire facsimile apparatus. The NCU 11 is connected to the public telephone line 28 and performs network control. The RAM 12 provides a work area for the CPU 10, a storage area for various data, and the like. The modem 13 modulates or demodulates facsimile data. The ROM 14 stores data such as programs to be executed by the CPU 10 and setting values. The EEPROM 15 stores various flags and setting data. The gate array 16 functions as an interface between the CPU 10 and each unit 21 to 26. The codec 17 performs encoding and decoding of facsimile data. The DMAC 18 mainly writes data to and reads data from the RAM 12.
[0026]
The reading unit 21 includes an image sensor, an LED light source, and the like, and reads images such as characters and figures from a document. The printing unit 22 prints an image such as a character or a graphic by using, for example, an inkjet method. The operation unit 23 includes a key switch group such as a numeric keypad and character keys, and transmits a command corresponding to a user's key operation to the CPU 10. The display unit 24 includes a display such as an LCD, and displays an operation state, operation guidance, and the like. The slot unit 25 includes a connector for connecting a storage medium C such as a smart medium or a compact flash, and a reader / writer that reads and writes data with the storage medium C while allowing the storage medium C to be inserted and removed. As a function. The external connection unit 26 is connected to the personal computer B via a cable when the facsimile apparatus A is used as a peripheral device, and exchanges data and signals with the personal computer B.
[0027]
Explaining the point, the facsimile apparatus A has a direct printing function of directly reading out and printing image data captured by a digital camera (not shown) and stored in the storage medium C in addition to the main facsimile communication function. . In addition to basic facsimile transmission / reception functions, facsimile communication functions include copy functions, polling functions, automatic reduction functions, broadcast transmission functions, memory transmission functions, fax transmission functions, timer transmission functions, communication management report output functions, and call recording functions. There are various functions that use the RAM 12 as a memory, such as a function, an answering machine function, a redial function, and a called number display function. Therefore, the RAM 12 is shared by the facsimile communication function and the printing function, and the size of the free space of the RAM 12 when performing printing varies depending on the usage status of the facsimile communication function.
[0028]
In addition, when the facsimile apparatus A directly reads out and prints image data from the storage medium C based on the direct printing function, the facsimile apparatus A collects a large number of images corresponding to the image data stored in the storage medium C together with one sheet. It has a function that can print a list, that is, a so-called thumbnail index print function. According to this index print function, a number of reduced images are printed as a list on a single sheet based on a list print pattern in a form of representing an image in a matrix, and the user selects a desired image by looking at the print result. Can be printed.
[0029]
By the way, at the time of list printing based on the index print function, for example, the main scanning direction of the printing operation by the ink jet method is set to the horizontal direction of the paper transported in the vertical direction, and is arranged along the vertical and horizontal directions of the paper. Multiple reduced images are printed.
[0030]
However, when printing the list, if the RAM 12 is also used for the facsimile communication function and the free space is small, expansion or reduction is performed via the RAM 12 in accordance with the printing operation in the main scanning direction (the lateral direction of the paper), and further The number of image data to be processed in parallel, such as conversion to print data, is limited. Also, there are image data having a large data size and a small one depending on the level of resolution, and image data having a large data size occupies a large amount of free space in the RAM 12. In other words, the free space in the RAM 12 is required to be as large as possible in order to process a plurality of image data simultaneously with a printing operation along the main scanning direction. However, since the free capacity of the RAM 12 varies depending on the use situation, if the list print pattern has a fixed number of image arrangements in the vertical and horizontal directions, the free capacity of the RAM 12 may satisfy the size corresponding to the number of image arrangements in the horizontal direction. Accordingly, there is a possibility that the required number of image data cannot be developed in the RAM 12 and the list cannot be printed.
[0031]
Therefore, the CPU 10 in the present embodiment changes the number of vertical and horizontal image arrangements based on the list print pattern according to the free capacity of the RAM 12 and the data size of the image data. Specifically, the CPU 10 calculates the upper limit number of image data that can be expanded and reduced with respect to the free capacity of the RAM 12 in accordance with the printing operation along the main scanning direction, and the number of image arrays along the horizontal direction of the paper based on the upper limit number. Is the maximum. At this time, even if the total number of images to be printed in a list per sheet is the same, the CPU 10 changes the ratio of the number of image arrays along the vertical and horizontal directions of the paper according to the free space of the RAM 12 and the data size of the image data.
[0032]
FIG. 2 is an explanatory diagram for explaining an example of changing the list print pattern. As an example, the total number of images to be printed in a list is 12, and the main scanning direction S of the printing operation is the horizontal direction of the paper P.
[0033]
As shown in FIG. 2A, when the free space of the RAM 12 is sufficiently large, the CPU 10 causes the image G to be printed based on a list print pattern of 3 × 4 in the vertical and horizontal directions of the paper P. That is, the free capacity of the RAM 12 at this time is set to a size that can expand and reduce up to four image data in accordance with the printing operation along the main scanning direction S. As a result, the CPU 10 arranges a maximum of four images in the horizontal direction of the paper P and arranges three images in the vertical direction of the paper P according to the total number of images.
[0034]
On the other hand, as shown in FIG. 2B, when the free space of the RAM 12 is relatively small compared to the image data, the CPU 10 is based on a list print pattern of 4 × 3 in the vertical and horizontal directions of the paper P. The image G is printed. That is, the free capacity of the RAM 12 at this time is set to a size that can expand and reduce up to three image data in accordance with the printing operation along the main scanning direction S, and cannot expand and reduce four or more image data. As a result, the CPU 10 arranges a maximum of three images in the horizontal direction of the paper P, and arranges four images in the vertical direction of the paper P according to the total number of images. It is changed according to the data size.
[0035]
[0036]
[0037]
Next, operations based on the index print function will be described with reference to the drawings.
[0038]
FIG. 3 is a flowchart showing a data processing procedure based on the index print function. First, the CPU 10 determines whether or not a user's key operation for starting list printing has been performed by the index print function (S1).
[0039]
When starting the list printing (S1: YES), the CPU 10 reads out the image data directly from the storage medium C inserted into the slot unit 25, and sequentially reduces the image data while developing it in the RAM 12 (S2). Here, the image data developed in the RAM 12 is data to be ejected by the printing operation in the main scanning direction S on the paper P, and is converted into printing data for buffering processing accompanying printing through development and reduction. Temporarily stored in the RAM 12. Note that it is desirable that image data having the same resolution is continuously read out, but image data having different resolutions may be read in a mixed manner.
[0040]
As the image data is successively expanded and reduced in this way, the CPU 10 checks whether there is image data that overflows the free capacity of the RAM 12 (S3).
[0041]
When there is image data that overflows with respect to the free capacity of the RAM 12 (S3: YES), the CPU 10 excludes the image data that has overflowed at that time, and the number of image data that has been developed using the free capacity of the RAM 12 so far. Is determined as the number of image arrays to be printed in the main scanning direction S (S4). In other words, the number of image data expanded without overflowing in the RAM 12 is the upper limit number that can utilize the free capacity of the RAM 12 to the maximum. Note that a standard value is set in advance as the number of image arrays to be printed along the main scanning direction S, and a number of image data corresponding to the standard value can be expanded and reduced using the free space of the RAM 12. May skip S3 and S4 and proceed to the next process (S5).
[0042]
When the number of image arrays to be printed along the main scanning direction S is determined, the CPU 10 performs a list printing process based on the number of image arrays (S5). In this list printing process, image data expanded and reduced via the RAM 12 is used as print data, and the image G is line-by-line with respect to one sheet of paper P according to the printing operation along the main scanning direction S. Be launched. That is, in the horizontal direction of one sheet P, the image G is printed side by side according to the upper limit number of image data that can be processed in parallel using the free capacity of the RAM 12. Note that in the vertical direction of the paper P, the images G are printed vertically in accordance with the number obtained by dividing the number of image arrangements in the horizontal direction from the number of all image data stored in the storage medium C. When the printing process for one line is completed along the horizontal direction of the paper P, the printing process for the next line is performed in the same manner. As a result, all the images G read from the storage medium C are printed as a list in a matrix-like thumbnail format on the single sheet P together with the designated numbers.
[0043]
When the list printing process is completed for all the image data stored in the storage medium C (S6: YES), the CPU 10 then shifts to a mode based on the direct printing function. Here, the CPU 10 determines whether or not the user has designated and input a favorite image number from among a plurality of images G that are printed as a list on a single sheet P through the above-described series of processing (S7). ).
[0044]
When the image number is designated and input by the user (S7: YES), the CPU 10 reads the image data corresponding to the number from the storage medium C, and performs direct printing processing based on the image data (S8). In this direct printing process, the image data read from the storage medium C is used as print data via the RAM 12, and one image is printed on one sheet. When a plurality of image numbers are designated and input, images are continuously printed for each sheet based on a plurality of corresponding image data.
[0045]
When the direct printing process is finished (S9: YES), the CPU 10 finally finishes the entire process and returns to the original standby state.
[0046]
In S9, when the direct printing process is continued without finishing (S9: NO), the CPU 10 continues the direct printing process as it is.
[0047]
In S7, when the image number is not designated and input by the user (S7: NO), the CPU 10 finishes this entire process and returns to the original standby state.
[0048]
In S6, when the list printing process is continued without finishing (S6: NO), the CPU 10 continues the list printing process as it is.
[0049]
If the image data does not overflow in the free capacity of the RAM 12 in S3 (S3: NO), the CPU 10 returns to S2 in order to continuously expand and reduce the next-order image data via the RAM 12.
[0050]
If the list printing is not started in S1 (S1: NO), the CPU 10 does not start the index printing process.
[0051]
Therefore, according to the facsimile apparatus A, the list print pattern is changed in accordance with the free space of the RAM 12 that is also used for various facsimile communication functions. The number of image arrays along the lateral direction of the paper P can be changed appropriately according to the number of image data that can be developed in the RAM 12 in accordance with the printing operation in the main scanning direction S. The image G can be printed in a list with the image P placed in the vertical and horizontal directions of a single sheet P. This leads to efficient use of the RAM 12 without increasing the capacity, and the facsimile apparatus A can be multi-functionalized by adding an index print function and the like together with the facsimile communication function.
[0052]
In addition, this invention is not limited to said embodiment.
[0053]
In the above embodiment, all images are printed as a list on one sheet. However, when all the images cannot be stored in one sheet, a plurality of images are printed as a list on a plurality of sheets. Also good.
[0054]
In addition, the CPU 10 expands and reduces the image data via the RAM 12, but the reduction of the image data may be realized by hardware configured with a logic circuit or the like.
[0055]
The reduced size of the image data, the vertical and horizontal intervals in the list printing pattern, the total number of images that can be printed on the list on one sheet, and the like may be fixed or variable. In particular, it is desirable that the total number of images that can be printed as a list on one sheet of paper is variable when all the image data for one sheet needs to be expanded in the RAM 12 at a time. Further, it is not always necessary to print a plurality of images in the same number in the vertical and horizontal directions. For example, the first row may be four columns and the second row may be three columns. Furthermore, to put it extremely, if the free space of the RAM 12 is extremely small, it may be a list print for one column in which only one image is printed in each row.
[0056]
Furthermore, in the above-described embodiment, the number of image arrangements is determined by determining overflow while sequentially fetching image data into the RAM 12, but the number of image arrangements may be determined according to a predetermined free space in the RAM 12.
[0057]
