Description

A method of producing a work of art or craft

Field of technology

The proposed invention falls within the field of creating works of art or crafts, such as paintings or collages in particular.

Current state of the art

The boundary between the definition of a work of art and a work of craftsmanship is not precisely anchored. The interpretation is usually that the author brings more of his own creative invention and fantasy into the work of art. A work of art, compared to a work of craftsmanship, is also understood as a work produced in a single or a few (almost) identical copies.

A craft work is understood rather in the way that its author (craftsman) creates the work rather according to predetermined rules, as is customary in the given area, while the level of his creative invention and imagination is required to be low or none. The craft work can also be produced in a larger number of pieces. However, for the purposes of this invention, the precise marking of the boundary is not essential. The described principle of the invention can be used both for a work of art and for a work of craftsmanship.

Nowadays, there are different approaches to creating works of art or craft based on a template. The basic solution is coloring books, where the template is marked with contour lines on the background material. The segments (fields) delimited by lines are filled with color either according to the author's imagination or according to the color template arranged next to it.

A special design of coloring books is the so-called coloring by numbers. In that case, each segment has a numerical code assigned to it (as a rule, the number is given directly in the segment). The legend indicates which digit is assigned which color. The segment with the appropriate number is then filled with the color according to the legend.

Document US 10991129 B2 describes a method of projecting colored lights onto a surface, which can create a temporary work of art or craft. The method includes selecting a color from a list of one or more colors using an application in a mobile electronic device, identifying the color of a surface onto which the selected color is to be projected, and determining the color of light to be projected onto the surface. This is done by the processor so that the color of the light combined with the color of the surface creates the selected target color.

On the obverse side of the background material, the author can show the original on the background material. By projecting the original onto the background material placed between the author and the projection device, a situation where the author shields the projected original with his own body is avoided, as is the case when the projection device is placed behind his back.

The essence of the invention

The essence of the invention is a method of producing a work of art or craft. The production consists in the treatment of the surface of the translucent base material. Translucent base material for the purposes of this invention means both a translucent material and an opaque material arranged in such a way that the material formed by it is translucent as a whole. Such a translucent material made of an opaque substance is, for example, wire, perforated sheet or expanded metal. It is obvious that between the parts made of opaque material there are holes through which light shines through.

Translucent background material is placed between the author and the projection equipment. Projection, or display device for the purposes of this invention means, for example, a monitor, display or projector, etc. The projector can be both digital (and possibly connected to a PC) and analog, which can contain individual images of the original with variously represented segments. What is essential is that the projection device is capable of emitting light radiation in a specific, defined and limited direction. The background material can be in direct contact with the projection device (this applies in particular to a monitor or display), or it can be arranged at a certain distance from the projection device (this applies in particular to a projector). The background material must be oriented with its front side facing the author and the reverse side facing the projection device. The face of the base material is the side whose surface is being treated.

Furthermore, with the projection device, at least one sub-segment of the mirror-turned original is shown by optically detectable radiation onto the reverse side of the background material. The original can be both digital and analog (physical). The digital master can be at least temporarily stored in the memory of a computing device that is included in the projection device or is connected to it. Alternatively, a camera that is connected to a projection device can capture a physical model and display it in real time as a digital model on the projection device. An analog original can be contained on motion picture, slide, etc.

By displaying at least one sub-segment on the reverse side of the translucent base material, this optically detectable segment is displayed (shows through) on its front side. This segment has a different luminance and/or color than the area of the face of the base material outside the segment shown. This definition means that the depicted segment can be lit while its surroundings are not. Conversely, the segment's surroundings can be illuminated and the segment itself can be represented by not being illuminated. It is also possible to consider a version where both the shown segment and its surroundings are illuminated, but in a different color. Color or chromaticity, for the purposes of this invention, means both a different color tone (hue, including gray) and a pattern (raster).

The author on the obverse adjusts the surface of all currently depicted segments recognizable on the obverse. Only one segment can be displayed at a time. In another embodiment, all segments of one type can be shown at a given moment (that is, intended for identical treatment of their surface). Alternatively, more than one, but not all, segments of one type may be represented. After modifying the surface of all segments shown at a given moment, their representation is terminated.

Further, at least once, a step is performed including the representation of other segments, the modification of their surface optically the same or different from the previously represented segments, and the termination of their representation after the modification of their surface. This step can be repeated until the artwork or craft is complete. Optically, the same adjustment is applied if not all segments of the given type have been shown in the previous step. This means that even in this next step, the same optical surface treatment is performed on the segments as in one or more previous steps. This division of the representation of segments for optically identical surface treatment into several production steps is particularly advantageous due to the clarity of the face of the base material during production, especially if there are a large number of segments of the same type. Furthermore, it can help at least partial drying (so-called "settling") of the binder or dye on the surface already

- 2 CZ 2023 - 56 A3 edited segments. This will reduce the risk of it blurring before the next, nearby segment is displayed. In contrast, the optically different surface modification applies especially if all segments of one type already have a modified surface.

Modification of the surface of the shown segments can be done by removing at least part of the underlying material. This includes, for example, scraping, etching, surface burning, etc.

Instead of or along with removing at least part of the surface of the segment, its surface can be modified by adding material. The added material is essentially arbitrary, the only thing that is important is that it is optically recognizable differently compared to other added material used. The added material may typically be selected from the group comprising at least dyes, metals, minerals, clays, biological material, synthetic or semi-synthetic compounds and materials. This means that the surface of the underlying material can be provided with a material having a certain color and/or texture. This allows for various paintings, collages, etc.

A computer program can advantageously be used to implement the above-described invention for a digitally displayed original. This contains instructions that, if the program is executed by a computer, cause the computer to perform some of the steps of the described method. These steps include at least temporarily displaying at least one sub-segment of the mirrored digital master using a projection device. The author can then adjust the surface of the face of the background material in place of the segments.

The computer program further causes the computer, upon completion of displaying the currently displayed segments, to perform a step at least once that includes temporarily displaying additional segments of the mirrored digital master using the projection device. The author can then adjust the surface of the face of the background material in the place of these segments in the same way or differently from the previously shown segments.

Said computer program can be at least temporarily stored on a computer-readable storage medium.

The present invention provides an innovative way of producing a work of art or craft. In contrast to the previously known methods described above, the base material is not provided with contour lines, so it is not necessary to overlap them. The method will allow even less gifted people to create a quality work according to the template; will allow to maintain the exact proportions of the individual parts of the work, the controlled gradual representation of the segments can prevent damage to the immature added material, and at the same time it eliminates the problem of visible contour lines and/or numbers.

An example of the implementation of the invention

In the method of producing a work of art, the translucent background material 1 is placed between the author 2 and the projection device 3 at time T0 (see Fig. 1 and Fig. 2). Projection device 3 in this case is a projector connected to a PC. The background material is oriented with its front side 4 towards the author 2 and the reverse side 5 towards the projection device 3.

The projection device 3 subsequently shows two sub-segments 6 of the mirror-turned digital original onto the reverse side 5 of the background material 1 by means of optically detectable radiation at time T1.

On the front side 4 of the base material 1, due to its translucency, the optically recognizable two sub-segments 6 are shown (see Fig. 3). The representation here is made by illuminating the surface of the segments 6, so that they have a higher luminosity than the non-illuminated area of the front side 4 of the base material 1 outside the segments 6 shown.

Author 2 on obverse side 4 adjusts the surface of both segments 6 shown at the given moment (noticeable on obverse side 4). The modification is done by adding a material, which here is the dye having the first shade.

After modifying the surface of both segments 6 shown at the given moment, the author 2 presses a button on the PC to end their representation at time T2. In the place of the previously shown first pair of sub-segments 6, the surface of the face side 4 is modified (see Fig. 4).

At time T3, two more segments 6 are shown for surface treatment optically the same as the segments 6 shown earlier (at time T1) (see Fig. 5). Author 2 on obverse side 4 modifies their surface again by adding material, which here is the dye having the first shade.

After adjusting the surface of both segments 6 shown at the given moment, the author 2 presses a button on the PC to end their representation at time T4. At time T4, there is already a modified surface on the front side 4 of the base material 1 in the place of two pairs of segments 6 (see Fig. 6).

At time T5, three more segments 6 are shown for a surface treatment optically different from that of segments 6 shown earlier (at times T1 and T3) (see Fig. 7). Author 2 on obverse 4 modifies their surface by adding material, which here is a dye having a second shade.

After adjusting the surface of all three segments 6 shown at the given moment, author 2 presses a button on the PC to end their representation at time T6. Thus, at time T6, the face of the base material 1 has a modified surface in all previously displayed segments 6 and the work of art is finished (see Fig. 8).
