Description

  The present invention relates to an information recording apparatus, an information recording method, and a recording program, and more particularly to an information recording apparatus, an information recording method, and a recording program for recording an image file on a recording medium with a high-definition number of pixels.

  In recent years, various services related to photography have been provided. For example, when a user takes a picture with a digital camera and brings a digital camera or digital camera media in which a photo image file is recorded to a photo shop such as a minilab, the photo shop uses an information recording device to remove the digital camera or media from the digital camera. There is a service for reading an image file and writing it on a recording medium such as a CD-R or a DVD-R (for example, JP-A-5-182373). Also, a still image file or a movie file obtained by shooting with a digital camera is converted into a file of a standard such as Video-CD or DVD-Video that can be played back on an image playback device such as a DVD player or a DVD recorder. There is also a service for writing to a recording medium such as -R or DVD-R.

JP-A-5-182373 (page 4-6, Fig. 3)

  In a digital camera, a series of image files is recorded as a file having the number of pixels determined by the imaging means. For example, when creating a Video-CD standard file based on a still image file obtained by a digital camera, Usually, the file is created after being converted into a standard number of pixels (360 × 240 pixels or the like) of the Video-CD standard. The standard number of pixels of the Video-CD standard is set so that a moving image of about 90 minutes can be reproduced on a CD-R having a capacity of about 700M. There is a problem that a high-quality image file obtained by the camera cannot be reproduced sufficiently.

  Here, when creating a movie file that can be played back on an image playback device based on a still image file obtained with a digital camera, a slide show movie file in which still images are displayed at regular intervals is created. Since the playback time of the recording medium is at most about several minutes to several tens of minutes, the capacity of the recording medium such as a CD-R has a sufficient margin, and a file is created with a higher definition pixel number than the standard pixel number. It is difficult to say that the current CD-R writing service makes full use of the capacity of the recording medium.

  In addition, the capacity of the image file itself to be recorded may exceed the recordable capacity of a recording medium such as a CD-R, DVD-R, or Blu-ray disc. In this case, the capacity of the image file is reduced. However, if the number of pixels of the image file is reduced, the image quality deteriorates and the number of pixels changes every time recording is performed, and the uniformity of the image file to be backed up is lost.

  The above-mentioned problem also occurs when converting an image file into a DVD-Video standard file for recording on a DVD-R, or when converting an image file into an HDTV standard file for recording on a Blu-ray disc. The same occurs not only when the image file is recorded on the recording medium, but also when the image file is recorded on an internal storage means such as a hard disk drive. Furthermore, not only when an image file is recorded, but also when another type of file is recorded.

  The present invention has been made in view of the above problems, and its main purpose is to provide a recording medium such as a CD-R / RW, a DVD ± R / RW, a DVD-RAM, or a Blu-ray disc, an HDD, or the like.

  In the present invention, the specific number of pixels is preferably the number of pixels selected from a range that can be set by a standard corresponding to the recording medium, and the recording medium is a CD-R / RW. Is more than 360 × 240 pixels, when the recording medium is DVD ± R / RW, more than 702 × 480 or 720 × 480 pixels, and when the recording medium is a Blu-ray disc, The number of pixels can be larger than 700 pixels in the vertical direction.

  Further, the information recording apparatus of the present invention is an information recording apparatus for recording one or a plurality of input files on a recording medium or storage means, and the means for inputting the file and the recording medium or the storage means can be recorded. Means for comparing the capacity with the total capacity of the file, means for compressing the file when the total capacity of the file is greater than the recordable capacity, and the compressed file or the compressed A file and a means for recording the input file in the recording medium or the storage means.

  In the present invention, it is preferable that the compression unit compresses the capacity of the file by reducing the color information or the number of frames without changing the number of pixels of the file.

  The present invention further includes means for converting the input file, the pixel-converted file, or the compressed file into a file of any standard of Video-CD, DVD-Video, or HDTV. In the recording means, at least one of the disk-converted file and the compressed file, or the pixel-converted file and the compressed file of the disk-type recording medium A configuration may be adopted in which the file converted from the standard is recorded in at least one of the files and an area inside the area where the input file is recorded.

  In the present invention, the file may be an image file based on a photographic image taken with a digital camera.

  In the recording program of the present invention, at least means for comparing the number of pixels of the input file with a predetermined specific number of pixels, and the number of pixels of the file differ from the specific number of pixels. In this case, the file is converted into the recording medium by means for converting the file so that the number of pixels becomes the specific number of pixels, the file with the converted number of pixels, or the file with the converted number of pixels and the input file. Function as a recording means.

  Also, the recording program of the present invention provides a computer for comparing at least the total capacity of one or more input files with the recordable capacity of a recording medium or storage means for recording the files, Means for compressing the file when the total capacity is larger than the recordable capacity, the compressed file, or the means for recording the compressed file and the input file in the recording medium or the storage means; It is to function as.

  The information recording method of the present invention includes a step of inputting a file, a step of comparing the number of pixels of the file with a predetermined specific number of pixels, the number of pixels of the file and the specific number of pixels. Are converted so that the number of pixels is equal to the specific number of pixels, the file with the converted number of pixels, or the file with the converted number of pixels and the input file At least recorded on the recording medium.

  The information recording method of the present invention includes a step of inputting one or a plurality of files, a step of comparing the recordable capacity of the recording medium or the storage means, and the total capacity of the files, A step of compressing the file when the total capacity is larger than the recordable capacity, and a step of recording the compressed file or the compressed file and the input file on the recording medium or the storage means And at least.

  Thus, in the information recording apparatus of the present invention, the number of pixels of the input file, and the specific number of pixels higher in definition than the number of pixels set as standard in the standard corresponding to the recording medium for recording the file, And a pixel number conversion means for converting the file so that the number of pixels becomes a specific number of pixels regardless of the number of pixels of the original file when the number of pixels is different. Thus, since the input file is always recorded on the recording medium with a high pixel count, the recorded file can be reproduced with high image quality.

  Further, the information recording apparatus includes a capacity comparison unit that compares a recordable capacity of a recording destination such as a recording medium for recording an input file or an HDD, and a total capacity of one or more input files, and a file When the total capacity of the file exceeds the recordable capacity of the recording destination, the file compression unit compresses the capacity without changing the number of pixels of the file, so that the input file is recorded on the recording medium with an appropriate capacity. Therefore, it is possible to prevent problems such as recording failure due to insufficient recording capacity at the recording destination.

  The information recording apparatus, information recording method, and recording program of the present invention have the following effects.

  The first effect of the present invention is that recording can always be performed on a recording medium with a high number of pixels regardless of the number of pixels of the input file.

  The reason is that the number of pixels of the input file is compared with the number of pixels comparing means for comparing the number of pixels higher in definition than the number of pixels set as standard in the standard corresponding to the recording medium for recording the file. This is because it includes pixel number conversion means for converting the file so that the number of pixels becomes a specific number of pixels regardless of the number of pixels of the original file when the number of pixels is different.

  In addition, the second effect of the present invention is that even when the capacity of the input file is large, it can be recorded in the recording destination as a file having an appropriate capacity without reducing the number of pixels. is there.

  The reason is that a capacity comparison means for comparing the recordable capacity of a recording destination such as a recording medium for recording the input file or HDD, and the total capacity of one or more input files, and the total capacity of the file This is because it includes file compression means for compressing the capacity without changing the number of pixels of the file when the recording capacity exceeds the recordable capacity of the recording destination.

  By using such means to record an image file acquired by a digital camera on a recording medium, the image file can be reproduced with a high number of pixels, and the utility value of the recording medium can be increased.

  In a preferred embodiment, the information recording apparatus of the present invention records file input means for inputting one or a plurality of image files from a digital camera or media, the number of pixels of the input image file, and the image file. The pixel number comparison means for comparing a specific pixel number with a higher definition than the standard pixel number of the standard corresponding to the recording medium, and when the pixel number is different, regardless of the pixel number of the original image file, the image A pixel number converting means for converting the number of pixels of the file to a specific number of pixels, a capacity comparing means for comparing the recordable capacity of the recording medium and the total capacity of the image file set to the specific number of pixels, and an image When the total capacity of the file exceeds the recordable capacity of the recording medium, file compression means that compresses the capacity without changing the number of pixels of the image file, and the number of pixels is converted or converted as necessary. File conversion means for converting an image file whose capacity has been compressed into a format that can be used by an image playback device, and a file recording means for recording the converted image file or the converted image file and the original image file Since it is provided at least and an image file is always recorded on a recording medium with a high number of pixels and an appropriate capacity, a recording medium with high utility value can be created.

  In order to describe the above embodiment in detail, an information recording apparatus, an information recording method, and a recording program according to a first example of the present invention will be described with reference to FIGS. 1 to 4 are external views schematically showing the configuration of the information recording apparatus according to the present embodiment. FIG. 5 is a block diagram showing the function of the information recording apparatus, and FIG. 6 is a flowchart showing the procedure of the information recording method of this embodiment. FIG. 7 is a diagram schematically showing a file recording area in the recording medium of the present embodiment, and FIG. 8 is a diagram schematically showing the structure of the recording medium (CD-R).

  As shown in FIG. 1, the information recording apparatus 1 of this embodiment is for a digital camera such as a smart media, a compact flash (registered trademark), a memory stick (registered trademark), an SD memory card, a multimedia card, or a mobile phone with a camera. For example, a medium loading unit 2 for loading a recording medium (hereinafter referred to as a medium 8), a photographing device (hereinafter referred to as a digital camera 7) such as a digital camera 7 or a camera-equipped mobile phone 7a, wired or wireless, File input means such as a device connection unit 3 for connection by infrared rays, a network connection unit for downloading a file from the server 19 via a communication network 18 such as the Internet, and the input still image file, moving image file, music sound file , Content files, application files A recording medium loading unit 4 for loading a recording medium 9 such as a CD-R / RW, DVD ± R / RW, DVD-RAM, Blu-ray disc, etc. An operation unit 6 such as a keyboard and a mouse and a display unit 5 such as an LCD and a CRT (a touch panel having both the operation unit 6 and the display unit 5 is shown in the figure) are provided.

  The function of the information recording apparatus 1 is shown in a block diagram as shown in FIG. That is, a file input unit 10 for inputting a file using the media loading unit 2, the device connection unit 3, a network connection unit, etc., an information input unit 11 such as a display unit 5 or an operation unit 6, and a pixel of the input file The number of pixels that compare with the number of pixels that can be set with the standard corresponding to the recording medium and the number of pixels that is higher in definition than the standard number of pixels (hereinafter referred to as a specific number of pixels). When the number comparison unit 12 and the number of pixels of the input file are different from the specific number of pixels, regardless of the number of pixels of the input file (that is, the number of pixels of the input file is greater than the specific number of pixels) The number of pixels conversion means 13a for converting an input file so that the number of pixels becomes a specific number of pixels and a file set to a specific number of pixels can be converted into a DVD player or a DVD player. File editing means 13 such as a file format conversion means 13b for converting to a file of a standard such as Video-CD, DVD-Video, HDTV, etc. that can be used by an image playback device such as a reader, and a converted file (the number of pixels is converted) A file recording unit 14 for recording the converted image file and the original image file on the recording medium 9.

  Note that the number of pixels of a file in this specification is a concept that includes not only the number of pixels of an image file but also the number of pixels of image information of a file that includes image information in part. In this embodiment, since the input still image file is converted into a moving image file that can be played back by an image playback device, the file editing means 13 is provided with the file format conversion means 13b. When the file is used on a personal computer or the like, it is not necessary to provide the file format conversion means 13b. Further, each of the above means may be configured as hardware in the information recording apparatus 1, and a recording program for causing the computer to function as at least the pixel number comparing means 12, the pixel number converting means 13a, and the file recording means 14 is installed. The above means may be executed by the recording program. 1 shows a kiosk-type information recording apparatus 1 that can be installed in a store such as a photo shop or a convenience store. However, the information recording apparatus 1 can be of any form, for example, as shown in FIG. It may be a dedicated set-top box, a portable writer as shown in FIG. 3, or the recording program may be installed in a personal computer having file input means 10 as shown in FIG. May be used.

  Next, a procedure until a file is recorded on the recording medium 9 by using the information recording apparatus 1 having the above configuration will be described with reference to a flowchart of FIG. In the following, a case where a moving image file in a format that can be played back by an image playback device is created from a still image file obtained by shooting with a digital camera will be described. However, when a moving image file such as avi is input, When converting a file into a moving image file such as mpeg1 or mpeg2 that can be played back on an image playback device, or when a still image file specific to a digital camera is input, the still image such as jpeg that can be played back on the image playback device The same applies to conversion to a file.

  First, in step S101, a recording medium 9 such as a CD-R / RW, a DVD ± R / RW, a DVD-RAM, or a Blu-ray disc is loaded into the recording medium loading unit 4 of the information recording apparatus 1. Any commercially available recording medium can be used as the recording medium 9, but file conversion may be performed only on the specific recording medium 9, in which case the recording medium is recorded in step S <b> 102. The recording medium 9 can be specified based on whether or not identification information for identifying the recording medium 9 is recorded in the predetermined area 9. The content of the identification information is not limited, but if the contents of the identification information are easily known, the identification information itself is also copied. Therefore, at least a part of the identification information is information that cannot be recorded by the computer OS, Specifically, information in the program memory area, information by guide groove modulation (ATIP: Absolute Time In Pre-groove) given at the time of CD-R molding, and the like are preferable.

  Here, the structure of a general recording medium 9 (CD-R) will be described with reference to FIG. 8. The CD-R is formed on a polycarbonate substrate 100 with an organic dye layer 101 such as cyanine, phthalocyanine, or azo. A reflective layer 102 made of silver or the like and a protective layer 103 are laminated to form a pit by applying a laser beam of a predetermined power to the organic dye layer 101 to decompose the dye and deform the substrate to form pits. Recording is performed, but the laser power has an optimum value depending on the type of the laser head that irradiates the laser beam and the type of the organic dye layer 101 to be used. -The drive side needs to recognize the recommended type of R type and laser recording power. Therefore, information such as the disc application code and recommended laser recording power is written as information by guide groove modulation (ATIP) at the recording medium manufacturing stage, and this information is read by the drive firmware. The laser power is adjusted by control. Since such guide groove modulation (ATIP) can only be created at the time of manufacture, copying at the user level can be prevented. Further, lead-in start time, maximum lead-out startable time, etc., which are guide groove modulation (ATIP) other than the above, can be used as identification information by appropriately setting.

  Next, in step S103, the medium 8 is loaded in the media loading unit 2 of the information recording apparatus 1, or the digital camera 7 is connected to the device connection unit 3, or the network connection unit is connected to the communication network 18, and in step S104, An image file stored in the digital camera 7 or the media 8 or an image file recorded in the server 19 is input using the file input means 10. The recording medium 9 loaded in the recording medium loading unit 4 may be an unused recording medium in which no file is recorded, or may be a used recording medium in which a file is recorded in advance.

  Next, in step S105, the pixel number comparison unit 12 is used to obtain the number of pixels of the file with reference to the header information of the input file, and the number of pixels of this file and a predetermined specific pixel. Compare the number. This specific number of pixels is the number of pixels selected from among the number of pixels that can be set according to the standard corresponding to the recording medium 9. Conventionally, an input file is set as a standard within the above range. The number of pixels to be recorded (for example, in the case of a CD-R, a moving picture file of about 360 minutes so that a moving picture file of about 90 minutes can be recorded in a capacity of 700 MB, and in the case of a DVD-R, a moving picture of about 90 minutes in a capacity of about 4.9 GB In this embodiment, the image data is converted to 720 × 480 pixels so that the file can be recorded, and in the case of a Blu-ray disc, the moving image file of about 2 hours is recorded in a capacity of about 20 GB. Then, in order to reproduce the file with higher image quality, the number of pixels with higher definition than the standard number of pixels (for example, more than 360 × 240 pixels in the case of CD-R) , Preferably 702 × 480 or 720 × 480 pixels, DVD-R has more than 720 × 480 pixels, preferably 1024 × 768 pixels, Blu-ray disc has more than 700 pixels in the vertical direction, preferably Is set to 1280 × 1024 pixels).

  If the number of pixels of the input file is different from the specific number of pixels in step S106, the number of pixels of the input file is converted into the specific number of pixels using the pixel number conversion means 13a in step S107. To do. Here, when the number of pixels is different, the number of pixels of the input file may be higher or lower than the specific number of pixels. In either case, the input file has a specific number of pixels. Convert to a number. For example, if the number of pixels in the input file is higher, the pixels in the file are thinned out to a specific number of pixels. If the number of pixels in the input file is lower, the file pixels are complemented. Let it be a specific number of pixels.

  Next, when creating a file that can be played back by an image playback device, in step S108, the file format conversion means 13b is used to create a slide predetermined for a file (still image file) set to a specific number of pixels. A file in a format that can be played back by an image playback device (eg, Video-CD for CD-R, DVD-Video for DVD-R, Blu-ray disc, etc.) by adding difference data based on the effect. In the case of HDTV standard file). Note that this step can be omitted if the file is not converted to a file that can be played back by the image playback device as described above. Here, the conversion of the number of pixels in step S107 and the conversion of the file format in step S108 are performed separately in this order, but this procedure is for convenience, and the conversion of the number of pixels is performed at the time of file conversion. If these processes can be performed, these processes may be performed simultaneously.

  In step S109, the data recording unit 14 is used to store at least one of a file set to a specific number of pixels and a file obtained by converting the file into a format that can be played back by an image playback device, or at least one of these and the original Are recorded on the recording medium 9. Here, when recording at least one of a file for an image playback device, a file set to a specific number of pixels, and an original image file on the recording medium 9, a recording area in which the file can be read is limited in the home appliance. Therefore, first, after writing a file for home appliances on the inner peripheral side of the logical address area of the recording medium 9, and closing the session as necessary, at least the file set to a specific number of pixels and the original image file One of the files, a reduced image file such as a thumbnail image file or a screen nail image file as necessary, an application such as a slide show program, a slide show setting file, an information file, etc. Write outside the file.

  When recording the file for the image playback device and at least one of the file set to a specific number of pixels and the original image file, various information is recorded on the recording medium 9 as shown in FIG. Identification information is recorded outside the innermost logical address area of the recording medium 9, a file for home appliances is recorded on the inner peripheral side of the logical address area located outside, and a specific area is specified in the outer area. At least one of the file set to the number of pixels and the original image file is recorded.

  As described above, in the information recording apparatus, the information recording method, and the recording program of the present embodiment, the input file is not recorded on the recording medium 9 as it is or after converting only the format, and corresponds to the recording medium 9. The input file is always recorded on the recording medium 9 with a high number of pixels in order to convert to a specific number of pixels higher than the standard number of pixels selected from the range that can be set by the standard. The recording medium 9 having high utility value can be created.

  Next, an information recording apparatus, an information recording method, and a recording program according to the second embodiment of the present invention will be described with reference to FIGS. FIG. 9 is a block diagram illustrating functions of the information recording apparatus according to the present embodiment, and FIGS. 10 and 11 are flowcharts illustrating a procedure of the information recording method according to the present embodiment.

  The function of the information recording apparatus 1 of the present embodiment is shown in a block diagram as shown in FIG. That is, a file input unit 10 for inputting a file using the media loading unit 2, device connection unit 3, network connection unit, and the like, an information input unit 11 such as the display unit 5 and the operation unit 6, and a recording destination (recording medium 9 Alternatively, the capacity comparison means 15 for comparing the recordable capacity of the internal storage means 17) such as an HDD and the total capacity of one or a plurality of input files, and the total capacity of the input files can be recorded at the recording destination. The file compression means 16 that compresses the capacity without changing the number of pixels of the input file and the file compressed to an appropriate capacity can be used in an image playback device such as a DVD player or a DVD recorder. A file editing means 13 such as a file format converting means 13b for converting into a file of a standard such as Video-CD, DVD-Video, HDTV, etc. A file recording unit 14 for recording the converted file (at least one of the compressed file and the converted standard file) or the converted file and the original image file in the internal storage unit 17 such as the recording medium 9 or the HDD. I have.

  In this embodiment, since the input still image file is converted to a moving image file that can be played back by the image playback device, the file editing means 13 is provided with the file format conversion means 13b. When the file is used on a personal computer or the like, it is not necessary to provide the file format conversion means 13b. In addition, each of the above means may be configured as hardware in the information recording apparatus 1, or a recording program for causing the computer to function as at least the capacity comparison means 15, the file compression means 16, and the file recording means 14 is installed. The above means may be executed by the recording program. Further, the information recording apparatus 1 of the present embodiment may be a kiosk type as shown in FIG. 1, a dedicated set top box as shown in FIG. 2, or a portable writer as shown in FIG. However, as shown in FIG. 4, a personal computer or a DVD recorder may be used.

  Next, a procedure until a file is recorded on the recording medium 9 using the information recording apparatus 1 having the above configuration will be described with reference to a flowchart of FIG. In the following, a case where a moving image file in a format that can be played back by an image playback device is created from a still image file obtained by shooting with a digital camera will be described. However, when a moving image file such as avi is input, When converting a file into a moving image file such as mpeg1 or mpeg2 that can be played back on an image playback device, or when a still image file specific to a digital camera is input, the still image such as jpeg that can be played back on the image playback device The same applies to conversion to a file.

  First, in step S201, a recording medium 9 such as a CD-R / RW, a DVD ± R / RW, a DVD-RAM, or a Blu-ray disc is loaded into the recording medium loading unit 4 of the information recording apparatus 1, and as necessary. In step S202, the recording medium 9 is specified based on whether or not identification information for identifying the recording medium 9 is recorded in a predetermined area of the recording medium 9.

  Next, in step S203, the medium 8 is loaded into the media loading unit 2 of the information recording apparatus 1, or the digital camera 7 is connected to the device connection unit 3, or the network connection unit is connected to the communication network 18, and in step S204, An image file stored in the digital camera 7 or the media 8 or an image file recorded in the server 19 is input using the file input means 10.

  Next, in step S205, the capacity comparison unit 15 is used to obtain the recordable capacity of the recording destination (the recording medium 9 or the internal storage unit 17 such as an HDD) (for example, when the recording medium 9 is the recording destination). The recordable capacity of the recording medium 9 is obtained from information recorded outside the logical address area of the recording medium 9), and the recordable capacity and the total capacity of one or more input files are obtained. Compare.

  If the total capacity of the input file exceeds the recordable capacity of the recording destination in step S206, the file compression means 16 is used to reduce the capacity of the input file in step S207. Perform compression. As a method for compressing the file, there is a method for reducing the number of pixels of the file. However, when the number of pixels of the file is reduced, the high-resolution file obtained by the digital camera is effectively used as shown in the first embodiment. You will not be able to. Therefore, in this embodiment, in order to reduce the capacity without changing the number of pixels, for example, in the case of a still image file, the color information of the still image file or the like is reduced, for example, the color is reduced from 16.670 million colors to 256 colors. In the case of a file, the capacity of the file is reduced to fit in the recording medium 9 by reducing the time information of the moving image file, such as by reducing the number of frames per second.

  Next, when creating a file that can be played back by an image playback device, a slide effect predetermined for a file (still image file) compressed to an appropriate capacity using the file format conversion means 13b in step S208. A file in a format that can be played back by an image playback device (for example, a Video-CD for a CD-R, a DVD-Video for a DVD-R, a Blu-ray disc) In this case, an HDTV standard file) is created. In this embodiment as well, this step can be omitted if the file is not converted to a file that can be played back by the image playback device. Here, the file compression in step S207 and the file format conversion in step S208 are performed separately in this order. However, this procedure is for convenience and, for example, when the number of frames per second is reduced. Since it is more convenient to compress the file at the time of file conversion, it may be configured to perform these processes simultaneously.

  In step S209, the data recording unit 14 is used to compress at least one of the file compressed to an appropriate capacity and the file converted into a format that can be played back by the image playback device, or at least one of these files and the original Are recorded on the recording medium 9 or the internal storage means 17. At this time, when recording at least one of the file converted into a format reproducible by the image playback device, the file compressed to an appropriate capacity, and the original image file on the recording medium 9, the file for home appliance is recorded on the recording medium. 9 is written to the inner periphery of the logical address area, the session is closed if necessary, and at least one of the file compressed to an appropriate capacity and the original image file, a reduced image file as required, and a slide show An application such as a program, a slide show setting file, an information file, and the like are written outside the home appliance file recorded at the end of the recording medium 9.

  As described above, in the information recording apparatus, the information recording method, and the recording program according to the present embodiment, the input file is not recorded as it is, or only the format is converted and is not recorded in the recording destination. Since the capacity is compressed and recorded without changing the number of pixels, the problem that the input file cannot be recorded on the recording medium 9 can be prevented, and the file can be recorded in the recording destination as an appropriate capacity file.

  In this embodiment, the capacity is compressed without changing the number of pixels of the file when the input file does not fit in the recording destination, but the first number that converts the number of pixels of the file into a specific number of pixels is used. It is also possible to combine the embodiment and the present embodiment that performs file compression. The procedure in that case will be described with reference to the flowchart of FIG.

  First, in step S301, a recording medium 9 such as a CD-R / RW, a DVD ± R / RW, a DVD-RAM, or a Blu-ray disc is loaded into the recording medium loading unit 4 of the information recording apparatus 1, and as necessary. In step S302, the recording medium 9 is specified based on whether or not identification information for identifying the recording medium 9 is recorded in a predetermined area of the recording medium 9.

  Next, in step S303, the medium 8 is loaded in the media loading unit 2 of the information recording apparatus 1, or the digital camera 7 is connected to the device connection unit 3, or the network connection unit is connected to the communication network 18, and in step S304, An image file stored in the digital camera 7 or the media 8 or an image file recorded in the server 19 is input using the file input means 10.

  Next, in step S305, the pixel number comparison means 12 is used to obtain the number of pixels of the file from the header information of the input file, and the number of pixels of this file and a predetermined specific number of pixels are obtained. Compare.

  In step S306, when the number of pixels of the input file is different from the specific number of pixels (including both cases where the number of pixels of the input file is higher than the specific number of pixels). In step S307, the number of pixels of the input file is converted to a specific number of pixels by thinning out or complementing the pixels.

  Next, in step S308, the capacity comparison unit 15 is used to acquire the recordable capacity of the recording medium 9 from information recorded in advance on the recording medium 9, and the recordable capacity and the specific number of pixels are set. Compare the total capacity of converted files.

  If the input file capacity exceeds the recordable capacity of the recording medium 9 in step S309, the file compression means 16 is used in step S308 without changing the number of pixels of the input file. The capacity of the file is compressed by reducing the color information of the still image file or the number of frames per second of the moving image file so that all the files can fit in the recording medium 9.

  Next, when a file that can be played back by the image playback device is created, a file of a format that can be played back by the image playback device is created using the file format conversion means 13b in step S310, and data recording is performed in step S311. Using the means 14, at least one of a file converted into a specific number of pixels and compressed in capacity as necessary and a file converted into a format that can be played back by an image playback device, or at least one of these files The file and the original image file are recorded on the recording medium 9. At that time, similarly, a file converted into a format that can be played back by an image playback device, a file converted into a specific number of pixels, and compressed in capacity as necessary, and at least one of the original image file are recorded on the recording medium 9. In the case of recording to a home appliance file, the file is written on the inner peripheral side of the logical address area of the recording medium 9, the session is closed as necessary, and then converted into a specific number of pixels. For home appliances in which at least one of a compressed file and an original image file, a reduced image file, an application such as a slide show program, a slide show setting file, an information file, etc. are recorded at the end of the recording medium 9 as necessary. Write outside of file.

  In this way, when the input file is not recorded on the recording medium 9 as it is or after converting only the format, it is recorded with a specific number of pixels, and the input file does not fit on the recording medium 9 By compressing the capacity without changing the number of pixels, a file can always be recorded with a high number of pixels, and a high-value recording medium 9 can be created.

  In each of the above embodiments, the file recorded in the digital camera 7 or the medium 8 is written to the recording medium 9. However, the present invention is not limited to the above embodiment, and any file can be written. For example, the present invention can be applied in the same manner when recording music files, contents, applications, etc. downloaded via the Internet.
