Description

  The present invention is open to a stereoscopic perception print original image creation method and a stereoscopic perception image forming method for creating an original image that enables printing in which a subject is perceived in three dimensions, and more specifically, using equipment such as glasses at all. In addition, the present invention relates to a stereoscopic perception print original image creation method and a stereoscopic perception image forming method that make it easy to perceive a subject stereoscopically by simply printing an original image obtained by processing a photographic image taken by a camera.

  A general stereoscopic photograph was viewed through stereoscopic glasses using the binocular parallax of an observer. In addition, as one that easily realizes stereoscopic viewing by lenticular stereo printing from only one original image without using stereoscopic glasses, one original image is taken with a digital camera, and software is executed by a personal computer. The original image is shifted laterally by various distances equal to or less than the pitch of the lenticular lens to generate a plurality of virtual images, and a plurality of virtual images are generated by the printer according to a print instruction from the personal computer. A stereoscopic image that can be observed as a 3D image using binocular parallax through a lenticular lens is printed by alternately printing in a vertical strip for each distance subdivided into the same number of virtual images. A stereoscopic image generation apparatus that performs this has been proposed (see, for example, Patent Document 1).

  In order to form other stereoscopic images, specify the protruding part to project the specified part by printing image information of photographic film on photographic paper and performing image processing of the image information captured by photoelectric conversion Save the information, create a mask based on this protrusion designation information, overlay the mask on the surface of the photocurable resin layer formed on the surface of the photographic paper, irradiate the light from the light source, then unexposed A method has been proposed in which a photocurable resin is removed to effectively form a three-dimensional image even with a small amount of photographic paper (see, for example, Patent Document 2).

Furthermore, as another stereoscopic image is formed, the surface of the paper is irradiated with a laser beam, and by removing the material of the portion and the portion without the recess, characters, patterns, photographs on the surface, It has been proposed to provide a paper processed product that is excellent in three-dimensional expression in which paintings and the like are expressed (see, for example, Patent Document 3).

However, in the stereoscopic image generating apparatus described in Patent Document 1, a stereoscopic image can be generated from only one original image. However, in order to observe a printed image as a stereoscopic image, it can be viewed through a lenticular lens. For example, it was necessary to install a lenticular lens on the front surface of a display screen of a television or to attach a lenticular lens to the surface of a photo frame.
In addition, the method for forming an image having unevenness described in Patent Document 2 requires a complicated printing apparatus having components that perform a mask formation process, a resin film formation process, a light irradiation process, an unexposed resin removal process, and the like. Thus, a stereoscopic image cannot be easily obtained.
Furthermore, the paper processed product described in Patent Document 3 requires a laser processing machine for processing the paper processed product, and a stereoscopic image cannot be easily obtained.

  Therefore, the present invention addresses such a problem, and the object can be easily perceived in three dimensions simply by printing an original image obtained by processing a photographic image taken with a camera without using any device such as glasses. It is an object of the present invention to provide a stereoscopic perception print original image creation method and a stereoscopic perception image forming method.

  Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a block diagram showing an embodiment of a stereoscopic perception print original image creation method according to the first invention. This stereoscopic perception print original image creation method creates an original image that enables printing in which a subject is perceived in three dimensions, and processed a photographic image taken with a camera without using glasses or other devices. By simply printing the original image, the subject is easily perceived in three dimensions. Hereinafter, the procedure will be described.

First, a photographic image including a subject and a background is digitized to obtain a digital image (step S1). At this time, whether a negative image (for example, 35 mm size) or positive film of a photograph taken with a film camera is read with a film scanner to create a digital image, or a digital image of a photograph taken with a digital camera is used. either will do. In addition, since the negative film has a wide range of bright and dark colors that can be recorded, the range of selection of color information is widened when digitizing. Thereafter, the obtained digital image is processed on the computer using image processing software.

  With respect to the acquired digital image, a step of cutting an image of a subject to be processed from a background image using image processing software is performed. At this time, first, a mask tool is used on the image processing software to mask around a necessary subject in the photograph (step S2). As a specific example, FIG. 2 shows a state in which a photographic image of a bird walking on the ground is surrounded by a mask (enclosed by a white broken line) as a subject. In addition, the photographic image as the above specific example uses an object in which light strikes the subject substantially uniformly and the background image is close to gray having an intermediate brightness. Then, when masking the periphery of the subject, it is preferable to enlarge the image processing software at an appropriate magnification so as to accurately mask the periphery of the subject.

  Next, the boundary between the subject and the background is repaired with the color on the subject side (step S3). This is because the boundary portion between the subject and the background is usually a mixture of both colors, so that when the subject image is pasted on a new background image created in a later step, the boundary portion appears dirty. Sometimes, the boundary portion is finished finely. After repairing in this way, the image of the subject subject is cut out from the background image (step S4).

  Next, a new background image for creating the clipped subject image is created (step S5). At this time, a new image frame having the same size as the original background image is created, and the gradation tool is used on the image processing software to gradually change the two colors from one color to the other in the image frame. Create a new background image by changing the color to. For example, white and yellow are designated, white is arranged at the top of the background image, yellow is arranged at the bottom, and the color is gradually changed from white to yellow near the center of the image.

  Next, the cut image of the subject is pasted on the created new background image (step S6). Thereafter, the background image on which the subject image is pasted is shaded on the background image around the subject (step S7). At this time, on the background image of the outer periphery of the subject, adjust the shadow direction, shadow shade, shade blur strength, shadow width size, etc. mainly on the lower side of the subject according to the degree of perception. And shading. This process may be repeated several times until an optimum result is obtained while the operator observes the display image on the computer. Next, the subject and the shadow are combined on the background image (step 8). This completes the creation of the original image that enables printing in which the subject is perceived in three dimensions.

  FIG. 3 is a photograph showing a specific example of the original image for printing created as described above. In this example, in FIG. 2, the image of the subject is cut out from the background image in a state where the subject (bird) is surrounded by a mask, and the subject is placed on the new background image created by the gradation tool using, for example, white and yellow. Is pasted, the subject (bird) is shaded on the background image corresponding to the outer peripheral portion of the subject, and the subject and the shadow are combined on the background image.

  FIG. 4 is a block diagram showing an embodiment of a stereoscopic perception print original image creation method according to the second invention. In this embodiment, an image of a subject subject is separated from a background image, and the original background image is used as it is as the background image of the subject. In this case, the present invention can be applied when the original background image is a beautiful background such as a sky and has a natural gradation.

  In FIG. 4, steps S1 to S2 are exactly the same as in the case of the first invention shown in FIG. In step S9, the subject image is separated into objects from the background image. On the other hand, the background image (original background image) after the subject image is separated is directly used as the background image (step S10). Then, the background image is shaded on the background image corresponding to the outer peripheral portion of the separated subject in the same manner as in step S7 of FIG. 1 (step S11). Next, similar to step S8 in FIG. 1, the subject and the shadow are combined on the background image (step S12). This completes the creation of the original image that enables printing in which the subject is perceived in three dimensions.

  In the above, the stereoscopic perception print original image creation method for creating an original image that enables printing in which the subject is perceived in three dimensions has been described. A perceptual image forming method will be described.

  FIG. 5 is a block diagram showing an embodiment of a stereoscopic image forming method according to the third invention. This stereoscopic perception image formation method prints an image in which a subject is perceived in three dimensions, and it is easy to print an original image obtained by processing a photographic image taken with a camera without using any equipment such as glasses. The subject is perceived in three dimensions. Hereinafter, the procedure will be described.

  The embodiment of FIG. 5 forms a stereoscopic image using an original image for printing created in correspondence with the stereoscopic image printing original image creation method according to the first invention shown in FIG. Steps S1 to S7 are exactly the same as in the case of the first invention shown in FIG. Next, as in step S8 in FIG. 1, the subject and shadow are combined on the background image to create an original image that enables printing in which the subject is perceived in three dimensions (step S13). Thereafter, the created original image for printing is printed by a printer (step S14). This completes the formation of an image in which the subject is perceived in three dimensions. Note that when photographic paper is printed by a printer, it is preferable to print, for example, in wide four cuts as a size at which the effect of stereoscopic perception can be recognized remarkably.

FIG. 6 is a block diagram showing an embodiment of a stereoscopic image forming method according to the fourth invention.
The embodiment of FIG. 6 forms a stereoscopic image using a print original image created in correspondence with the stereoscopic image print original image creation method according to the second invention shown in FIG.
