[0031]
The print setting unit 131 is used to make settings related to printing such as an aspect ratio when printing an image. Setting information such as the aspect ratio is supplied to the system controller 115. The frame display unit 132 displays a frame W (predetermined frame) in the optical viewfinder 14. In the present embodiment, the aspect ratio of the image sensor 112 is 4: 3, which is generally used in a CCD or the like, and the image signal read from the image sensor 112 has the aspect ratio of 4: 3. , And is recorded in the memory card 100 after being compressed.
[0032]
Next, the operation of changing the aspect ratio of the display image and the frame display will be described.
[0033]
The aspect ratio at the time of printing an image to be printed (hereinafter, referred to as “print aspect ratio”) is set to 4: 3 as a default.
[0034]
First, it is assumed that the print aspect ratio is set to 4: 3, and that a sheet having an aspect ratio of 4: 3 is set as the print sheet 200. In this case, the image signal read from the image sensor 112 is processed at the aspect ratio of 4: 3 and is displayed on the image display LCD 15 such as a liquid crystal panel at the aspect ratio of 4: 3. The image is compressed and recorded on the memory card 100. When this image signal is printed, the image signal is printed on a print sheet 200 having an aspect ratio of 4: 3, and the entire area of the captured image is printed.
[0035]
Next, from the state where the print aspect ratio is set to 4: 3, when a panorama type having an aspect ratio of 3: 1 is set as the print paper 200 and the print aspect ratio is changed to 3: 1, the print aspect ratio (3 1) is output from the print setting unit 131 to the system controller 115. The system controller 115 outputs a control signal to the display circuit 118 so as to have the same aspect ratio as the set print aspect ratio of 3: 1. Then, the display circuit 118 changes the aspect ratio according to the control signal so that the aspect ratio of the image to be displayed on the image display LCD 15 (hereinafter, referred to as “screen display aspect ratio”) becomes the same as the aspect ratio 3: 1. Perform processing.
[0036]
This aspect ratio changing process is performed by, for example, a mask process. FIG. 4 is a diagram illustrating an example of an aspect of the aspect ratio changing process. 10A shows the state before the screen display aspect ratio is changed (for example, the aspect ratio is 4: 3), and FIGS. 10B and 10C show the state after the change. When the set print aspect ratio is 3: 1, by applying a black mask process to the upper and lower portions of the display screen as shown in FIG. The same processing as in step 1 is performed. In the case of the wide TV type having the set print aspect ratio of 16: 9, as shown in FIG. 3B, the mask process is performed similarly, and the aspect ratio is apparently the same as the aspect ratio of the print paper 200 of 16: 9. The following processing is performed.
[0037]
Note that, as long as the screen display aspect ratio can be changed, the aspect is not limited to the mask processing in which the screen display aspect ratio is apparently changed. For example, the mask processing may be performed on the left and right portions, or the screen may be reduced vertically or horizontally instead of the mask processing.
[0038]
In the present embodiment, a frame W indicating an imaging range of a subject to be imaged in the optical viewfinder 14 is displayed. FIG. 5 is a diagram illustrating a display example of a frame W in the optical viewfinder 14. The frame W is displayed on a liquid crystal, but is not limited to the liquid crystal display as long as a plurality of types of the frame W can be switched and displayed. For example, a transparent plate or the like to which a frame W corresponding to various aspect ratios is added in advance A configuration in which the switching is controlled in a controlled manner may be employed.
[0039]
The frame W displayed in the optical viewfinder 14 is changed and controlled by the frame display changing process according to the setting of the print aspect ratio. For example, when the print aspect ratio is a normal 4: 3 state, a frame W1 is displayed in the optical viewfinder 14 as shown in FIG. If the print aspect ratio is changed to the panorama type 3: 1 from this state, information on the print aspect ratio (3: 1) is output from the print setting unit 131 to the system controller 115. The system controller 115 controls the frame display unit 132 to display a frame having the same aspect ratio as the set print aspect ratio of 3: 1, and controls the position of the frame display in the optical viewfinder 14. As a result, as shown in FIG. 5B, a frame W2 corresponding to an aspect ratio of 3: 1 is displayed in the optical viewfinder 14 instead of the frame W1.
[0040]
In the case of a wide TV type having a print aspect ratio of 16: 9, although not shown, a frame W corresponding to the aspect ratio of 16: 9 is displayed in the optical viewfinder 14 by the same processing.
[0041]
In the aspect ratio changing process on the image display LCD 15, images before and after recording can be displayed. Therefore, the screen display aspect ratio can be changed for any of the images. In this case, since only the unrecorded image at the time of imaging is displayed on the optical viewfinder 14, when printing a recorded image, matching between the visible image and the frame display change cannot be achieved. Therefore, when a recorded image is to be printed, it is desirable that the frame display change processing be automatically stopped.
[0042]
According to the present embodiment, the aspect ratio of the image displayed on the image display LCD 15 is changed in accordance with the set print aspect ratio, so that the recorded image and the subject image to be captured are printed. The image range is clearly seen on the image display LCD 15. Therefore, for example, when the user intends to print a stored image or to capture a landscape or the like, the aspect ratio of the image displayed on the image display LCD 15 is the same as the aspect ratio at the time of printing. Since the same area as the image confirmed on the image display LCD 15 is printed, the composition can be easily determined. Therefore, it is possible to easily determine the optimum composition at the time of printing or imaging.
[0043]
Further, since the frame display in the optical viewfinder 14 is changed according to the set print aspect ratio, the image range to be printed with respect to the subject image to be picked up can be clearly understood by the optical viewfinder 14. Therefore, it is possible to easily determine the optimum composition at the time of imaging.
[0044]
It should be noted that the configuration may be such that one of the aspect ratio changing process on the image display LCD 15 and the frame display changing process on the optical viewfinder 14 is selectively executed as desired by the user.
[0045]
(Second embodiment)
In the first embodiment, the print aspect ratio is set by the print setting unit 131. However, in the second embodiment, information indicating the aspect ratio of the print paper 200 is stored in the print cartridge 207 to be mounted. The control in the case where it is added in advance will be described. Therefore, except for the configuration in which the aspect ratio information of the print cartridge 207 is supplied to the system controller 115, the apparatus configuration, the aspect ratio change processing, and the frame display change processing are the same as in the first embodiment.
[0046]
A manual mode in which the print aspect ratio set by the print setting unit 131 is applied and an automatic mode in which the print aspect ratio added to the print cartridge 207 is applied as the print aspect ratio used for control by the system controller 115 are optional. May be settable. In this case, the control mode described in the first embodiment is used in the manual mode, and the control mode described below is used in the automatic mode.
[0047]
FIG. 6 is a diagram illustrating the print cartridge 207 according to the present embodiment. In the print cartridge 207, information (hereinafter, referred to as “aspect ratio information”) indicating the aspect ratio of the contained print paper 200 is additionally set in advance. The addition of the aspect ratio information is realized by adding a predetermined notch shape M to a part of the outer edge of the print cartridge 207, for example, as shown in FIG. Alternatively, as shown in FIG. 3B, the printing can be realized by printing a predetermined electrode E on a part of the print cartridge 207. The aspect of adding the aspect ratio information is not limited to these.
[0048]
When the print cartridge 207 is mounted, the aspect ratio information is mechanically read out from the cutout shape M when the print cartridge 207 is as in the example of FIG. In such a case, the data is electrically read from the electrode E. Then, the read aspect ratio information is supplied to the system controller 115, so that the system controller 115 grasps the aspect ratio of the attached print paper 200.
[0049]
The system controller 115 outputs a control signal to the display circuit 118 so as to have the same aspect ratio as the aspect ratio defined by the aspect ratio information. Subsequent processing is the same as the aspect ratio changing processing in the first embodiment. The system controller 115 also controls the frame display unit 132 so that the aspect ratio is the same as the aspect ratio defined by the aspect ratio information, and similarly to the frame display change processing in the first embodiment, the optical viewfinder 14. To control the position of the frame display inside.
[0050]
For example, when a print cartridge 207 containing a panorama type in which the aspect ratio of the print paper 200 is 3: 1 is attached to the main body, the read 3: 1 aspect ratio information is output to the system controller 115, and As a result of the above processing, a screen display as illustrated in FIG. 4B is displayed on the image display LCD 15 and a frame display as illustrated in FIG. 5B is displayed in the optical viewfinder 14, respectively. This is performed in the same manner as in the first embodiment.
[0051]
According to the present embodiment, not only the same effects as in the first embodiment are achieved in facilitating the determination of the optimum composition at the time of printing or imaging, but also the user can set the printing aspect ratio one by one. Even if the print cartridge 200 with the aspect ratio information is simply mounted, the screen display and the frame display in the viewfinder that match the aspect ratio of the print paper 200 are performed, so that the usability is improved.
[0052]
In the first and second embodiments, the print aspect ratio is recognized by displaying a frame in the optical viewfinder 14. However, the present invention is not limited to this. As long as the region display allows the region to be recognized, other configurations other than the frame display, such as, for example, vertical and horizontal masking, may be adopted.
[0053]
Another object of the present invention is to supply a storage medium storing program codes of software for realizing the functions of the embodiments to a system or an apparatus, and a computer (or CPU, MPU, or the like) of the system or the apparatus stores the storage medium. It is also achieved by reading and executing the program code stored in the.
[0054]
In this case, the program code itself read from the storage medium realizes the functions of the above-described embodiment, and the storage medium storing the program code constitutes the present invention.
[0055]
Further, as a storage medium for supplying the program code, for example, a floppy (registered trademark) disk, hard disk, magneto-optical disk, CD-ROM, CD-R, CD-RW, DVD-ROM, DVD-RAM, DVD -RW, DVD + RW, magnetic tape, nonvolatile memory card, ROM, and the like can be used.
[0056]
When the computer executes the readout program code, not only the functions of the above-described embodiment are realized, but also an OS (Operating System) running on the computer based on the instruction of the program code. This also includes a case where some or all of the actual processing is performed and the functions of the above-described embodiments are realized by the processing.
[0057]
Further, after the program code read from the storage medium is written into a memory provided in a function expansion board inserted into the computer or a function expansion unit connected to the computer, the function expansion is performed based on the instruction of the program code. This also includes the case where the CPU or the like provided in the board or the function expansion unit performs part or all of the actual processing, and the processing realizes the functions of the above-described embodiments.
