Note that the unit of image information embedded in the image data is not limited to the above example.

  Next, the image output apparatus will be described. FIG. 3 is a block diagram showing an internal configuration of the image output apparatus according to the embodiment of the present invention. An image output apparatus (hereinafter referred to as a printing apparatus) 100 shown in the figure is installed in a store such as a DPE store or a home appliance mass retailer, and is used by a general user. It is suitable for printing a printed image.

  Image data recorded on the recording media 76 of various digital cameras is read by the recording media reader / writer 108 and temporarily stored in the work memory 130 via the memory controller 106.

  The touch panel 122 is arranged on the display 124, and is an input unit for selecting an image to be printed by touching the image displayed on the display 124, or designating the number of prints, the size of the print paper, the print magnification, and the like. Function as. The billing device 128 performs, for example, cash collection by a coin machine and change processing according to the number of prints designated by the touch panel 122.

  The calculation unit 112 is a block for performing various calculations described later, and the trimming unit 114 is a block for trimming an image to be printed as necessary.

  When the image data read from the recording medium is RAW data (unprocessed image data output from an image sensor such as a CCD), the RAW development engine 116 performs linear matrix processing, white balance processing, Data that can be output to the display 124 or the like is generated by performing a synchronization process or the like.

  The RGB / YMC (K) conversion circuit 118 converts R, G, B data subjected to various types of image processing into Y, M, C, (K) (yellow, magenta, cyan, (black)) data. The converted Y, M, C, (K) data is output to the printer 110.

  As the printer 110, for example, a printer that employs a TA (Thermo Auto Chrome) system as a printing system can be used. The TA type printer is a color photographic paper (hereinafter referred to as “TA paper”) itself having each of C, M, and Y coloring layers, which is colored by heat and fixed by irradiation with light of a predetermined wavelength. It has means for conveying TA paper, a thermal head, a fixing lamp, and the like. When printing a color image on TA paper, the TA paper is first transported and the thermal head is controlled by Y data to develop the yellow layer of the TA paper, and then the yellow color is fixed by the fixing lamp. Color development of the magenta layer and cyan layer of TA paper is similarly performed based on the M data and C data, thereby printing a color image on the TA paper. The printer 110 of this embodiment is a TA printer. However, the present invention is not limited to this, and the present invention can be applied to other types of printers such as other thermal printers and inkjet printers.

  Next, the printing operation by the printing apparatus 100 having the above configuration will be described with reference to the flowchart of FIG. FIG. 4 is a flowchart showing the printing operation by the printing apparatus of this embodiment.

  First, image data is input from the recording medium 76 inserted in the recording medium reader / writer 108 of the printing apparatus 100 or the imaging apparatus 10 connected to the communication I / F 120, and an image to be printed is selected by the touch panel 122. (Step S30). Then, from the image data selected in step S30, the image pickup surface size (Xp [pixel], Yp [pixel]) of the image pickup device CCD18, the pixel density (Xc [pixel / mm], Yc [pixel / mm]) of the CCD 18; Image information such as the distance (L [mm]) between the imaging surface of the CCD 18 and the subject and the focal length (f [mm]) of the lens of the optical system 16 are acquired (step S32).

  Next, the calculation unit 112 calculates the diagonal length d [mm] of the CCD 18 (step S34). Here, a method for calculating the diagonal length d [mm] of the CCD 18 will be described. FIG. 5 is a plan view showing the image sensor. As shown in FIG. 5, the length w [mm] in the horizontal (X) direction and the length h [mm] in the vertical (Y) direction of the CCD 18 are expressed by the following equations (1) and (2), respectively. The

w = Xp / Xc (1)
h = Yp / Yc (2)
Therefore, the diagonal length d [mm] is calculated by the following equation (3).

d = (w ² + h ² ) ^1/2 (3)
The EXIF tag information of the image data includes the length w [mm] in the horizontal (X) direction and the length h [mm] in the vertical (Y) direction of the CCD 18 and the diagonal length d [mm] in advance. Also good. In this case, the above calculation step can be omitted.

  Returning to the description of the flowchart of FIG. 4, the process then proceeds to step S36, where the diagonal angle of view (θ [rad]) is calculated, and the diagonal length of the imaging range (diagonal length D [mm]) is calculated (step). S38). FIG. 6 is a diagram schematically illustrating the positional relationship between the imaging element and the imaging range during imaging. Since tan (θ / 2) = (d / 2f) from FIG. 6, the diagonal view angle θ [rad] is expressed by the following equation (4).

θ = 2 · arctan (d / 2f) (4)
When θ is expressed in degrees [deg], θ = (180 / π) × 2 · arctan (d / 2f).
The diagonal imaging length D [mm] is calculated by the following equation (5).

D = 2L · tan (θ / 2) (5)
The vertical and horizontal lengths (actual dimensions) of the imaging range 140 imaged by the imaging device 10 are calculated from the diagonal length of the imaging range 140 thus obtained and the aspect ratio of the CCD 18. The photographing magnification is expressed by the following formula (6).

(Shooting magnification) = f / L
= D / (2L · tan (θ / 2))
= D / D (6)
The diagonal imaging length D [mm] may be calculated by the imaging device 10 and embedded in the image data.

  Returning again to the description of the flowchart of FIG. 4, the process then proceeds to step S <b> 40, a print magnification input acceptance screen is displayed on the display 124, and the print magnification is input by the touch panel 122. Here, the print magnification is a magnification with respect to the actual size of the imaging range.

When it is input that the image is printed at the print magnification displayed in step S44, the print paper size input acceptance screen is displayed on the display 124, and the print paper size is input by the touch panel 122 ( Step S46). Then, it is determined whether or not the image fits on the input size print paper (step S48). If it is determined in step S48 that the image fits on the print paper, the process proceeds to step S52. On the other hand, if it is determined in step S48 that the image does not fit on the print paper, the image is trimmed (step S50). In step S50, trimming is performed by accepting designation of a range (for example, two diagonal points) to be printed by the touch panel 122. Then, image data for printing is created based on the pixel density (Xd [dot / mm], Yd [dot / mm]) of the printer 110 (step S52).

  Next, a screen for selecting whether or not to print the print magnification on the printing paper on which the image is printed is displayed on the display 124 (step S54). When printing the print magnification in step S54, the print magnification is printed (step S58), and the image is printed (step S60). On the other hand, if the print magnification is not printed, the image is printed as it is (step S60).

  Next, another embodiment of the printing operation by the printing apparatus 100 having the above configuration will be described with reference to the flowchart of FIG. FIG. 10 is a flowchart showing another example of the printing operation by the printing apparatus of the present embodiment. In this embodiment, the print magnification is automatically set based on the size of the print paper designated by the user.

The print magnification is calculated so that the entire image fits on the print paper (step S84).

  Next, a screen for selecting whether or not to print the print magnification on the printing paper on which the image is printed is displayed on the display 124 (step S86). When printing the print magnification in step S86, the print magnification is printed (step S88), and the image is printed (step S90). On the other hand, if the print magnification is not printed, the image is printed as it is (step S90).
