Description

CROSS REFERENCES RELATED TO THE APPLICATION FIELD OF THE INVENTION

This invention relates generally to graphical editing technologies, and more particularly, to controlling applications of effects by using mask.

BACKGROUND OF THE INVENTION

With the increasing popularity of computing and the use of the Internet in many fields, the ability to control computers and similar devices in a simple, convenient manner has become extremely important. However, existing interfaces to computers and similar devices can be cumbersome and complicated.

In particular, many users of graphical editing programs would benefit from an improved interface used to control the application of various special effects onto an image. For example, graphical editing programs would benefit from improved control of the application of the effects with respect to the intensity and the area of the image that is being subjected to modification by application of the effect.

Some software applications implement mask that are similar to applying a cut out or stencil to protecting area of the underlying image. They also implement control that applies effects only to a localized area, similar to a street paint tool. A mask is described in US-A-2002/0093514 which can be positioned and dynamically moved over an image such that an effect is applied outside of the masked portion of the image. In EP-A-0 853 426 , a plurality of mask patterns are registered, and a desired one among the plurality of registered mask patterns is selected. A desired part of a taken image is cut out using the desired mask pattern to synthesize a new image, which is stored.

DETAILED DESCRIPTION

In the following detailed description of the embodiments of the invention, references are made to the accompanying drawings in which like references indicate similar elements, in which, is shown by way of illustration of specific embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention and it is to be understood that other embodiments may be utilized and that logical, mechanical, electrical and other changes may be made without departing from the scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined only by the appended claims.

A. General System Architecture

Beginning with an overview of the operation of the invention, Figure 1A illustrates a system 100 which can control the effects of image manipulation according to one embodiment of the present invention. System 100 includes server 101 and one or more clients 103. Stored in memory resident within server 101, a typical software application 104 is an image-editing package adapted to manipulate images provided by client 103. The operations of software application 104 may be controlled by server 101 or through control information from client 103. Within the software application 104, an effects block 110 and a mask block 112 reside. These "blocks" denote a collection of one or more instructions, including but not limited to a routine, function, or any other process. The effects block 110 applies a specific effect to the image and the mask block 112 selectively limits the area of the image which is modified by the effects block 110.

As shown in Figure 1B, client 103 may establish communications with server 101 through a wide area network. For instance, client 103 may communicate directly with an Internet Service Provider (ISP) that communicates with server 101.

A client 103 represents any device that may enable user's online access to information. Illustrative examples of a "client" may include, but are not limited or restricted to a digital camera, a stand-alone device to view images inclusive of a kiosk, a hand-held image viewing device (e.g., portable computer, personal digital assistant, iPOD® or other music/video/image viewing device, etc.), a camera cellular phone, and the like. In this embodiment, client 103 may provide a user interface to communicate information to the user. It should be noted that although Figure 1A illustrates only two modules performing the above functionality, more or less modules may be used to perform this functionality.

One exemplary embodiment of client 103 is a digital camera 140 that is illustrated in Figure 1C. For this embodiment, digital camera 140 includes a processor 150, a memory 155 and an input/output device 160 coupled to a bus 165. Input/output device 160 includes an interface to establish a wired or wireless communication path with server 101. Memory 155 is configured to store images that are captured by digital camera 140 and processed by processor 150.

Memory 155 encompasses various types of computer readable media, including any type of storage device that is accessible by processor 150. One of the skilled the art will immediately recognize that the term "computer readable media" encompasses any suitable storage medium such as a programmable electronic circuit, any type of semiconductor memory device such as a volatile memory (e.g., random access memory, etc.) or non-volatile memory (e.g., read-only memory, flash memory, etc.), a hard drive disk, or any portable storage such as a floppy diskette, an optical disk (e.g., compact disk or digital versatile disc "DVD"), memory stick, a digital tape or the like.

Of course, it is appreciated that digital camera 140 may be controlled by operating system software including instructions executed by processor and stored in internal memory. Also, software application 104 may be implemented within memory 155 or another memory component that is integrated within processor 150 or external to processor 150 in lieu of or in addition to such storage within server 101. Thus, the digital camera 140 may perform masking operations and applying effects to the image directly.

As a first illustrative example, software application 104 may be loaded into server 101 to perform the masking and application of effects on an image as described below. These masking operations are controlled by digital camera. According to a second illustrative example, the software application 104 may be loaded within digital camera 140 to perform the masking and application of effects on an image, but the mask is fetched by digital camera 140 from memory implemented within server 101. According to a third illustrative embodiment, a high-resolution image targeted for manipulation is loaded on server 101 while a low-resolution image loaded in digital camera 140. In response to selected operations on the low-resolution image, corresponding operations are performed on the high-resolution image.

B. Embodiments of the Mask

Figure 2A illustrates a first embodiment of a mask as described in block 112 of Figure 1A. Display 200 represents a sample screen while utilizing the software application 104 (Figure 1A). A mask 210 is shown on the display 200, where mask 210 features one or more graphical representations. These graphical representations may have a predetermined shape and size and/or may be set by the user to produce a customizable graphical representation. The predetermined forms of mask 210 may be preloaded into the digital camera during manufacturer or downloaded from a source over a network connection. The customized graphical representations of mask 210 may be stored within digital camera upon completion by the user, and may be transmitted to the server 101 for storage.

For instance, as shown in Figure 2A, the embodiment of mask 210 is translucent and is defined by the clear outline. The mask 210 allows a selective application effects from the effects block 110 (Figure 1A) by moving the mask 210 with respect to a static image as shown on the display 200. The portion of the static image as shown on the display 200 which is within the mask 210 is not modified by the application of the effects. This static image may be still image or an image from a video stream.

Furthermore, the mask 210 is capable of being dynamically moved with respect to the static image during the application of the effects. This allows the user to selectively apply the effect by interactively moving the mask simultaneously while applying the effect.

Another embodiment includes a mask that is able to interact directly with a localized image editing operation. For example, the mask may become entirely transparent in the immediate area where a user is currently applying an image effect. This allows the user to see the entire area that is mask without a mask or line obstructing the immediate work area.

Figure 2B illustrates a second embodiment of mask 215 represented on display 200. Mask 215 shows the portion within mask 215 to have a cross-hatched shading. Any type of shading can be utilized to illustrate the portion within the mask.

Figure 2C illustrates a third embodiment of the mask represented on display 200. According to this embodiment, the shape of the mask can be easily created and modified. For example, within the display 200 there area first mask 220, a second mask 230 and a third mask 240. Each of the first, second and third masks (220, 230, and 240) have different sizes and may function independently or may be combined to form a single mask. Naturally, this specific example utilizes three portions to form independent or combined masks and any number of portions may be utilized to accomplish the same.

Like masks that take different sizes, masks may also take any multitude of shapes. The masks may simulate the use of a fixed edge such as a French Curve. The shape of the mask is infinitely changeable. Furthermore, the user may mask as much area of the image as desired and perform a global image effect on the entire image while protecting portions of the image from the image effects with the masks.

Figure 3 illustrates an exemplary embodiment of a screen display 300 featuring icons 310 representing various shapes for the mask. According to this embodiment, upon execution, a mask 320 is selected from icons 310 corresponding to a plurality of mask with graphical representations, namely different fixed shapes and sizes. Such selection may be accomplished by cycling through a series of mask icons 310 displayed on screen display 320 of a digital camera 330 using at least one control button 340 of digital camera 330. Alternatively, although not shown, such selection may be accomplished through a menu displayed on screen display 300 of digital camera 330, where the menu illustrates images or lists textual descriptions of the plurality of mask types. The selection of the menu entry is also controlled by control button(s) 340.

Figure 4 illustrates an exemplary embodiment of customization of the mask is shown. Display 200 of client 103 features an image 400. Using a stylus 410, for example, a pattern 420 is traced over image 400 illustrated by display 200. Upon completion of an enclosed pattern, a determination is made whether the area within the enclosed pattern 420 is selected to be the mask, illustrated in a transparent form, or whether the area outside the enclosed pattern 420 constitutes the mask. For instance, upon touching stylus 410 within a first area 430, namely the area within enclosed pattern 420 is considered to be the mask. As a result, when applied, an effect will be applied to the portion of image 400 outside first area 430 while no effect is applied inside first area 430 outlined by the mask. The transparent nature of the mask allows the user to see the lack of effects applied to the masked area. However, upon touching the stylus within a second area 440, namely the area outside enclosed pattern 420, any effect will be applied to the portion of image 400 inside first area 430 because the mask now covers second area 440.

C. Operations of the Mask

Figure 5 illustrates a flow diagram. At block 500, the application software 104 (Figure 1A) is initiated. The user may build, create, and/or modify the shape and size of the mask in Block 510. The user may position the mask relative to the static image (Block 520). The user may apply the image effect selectively to the image that is not masked by the mask (Block 530). The user may dynamically reposition the mask while simultaneously applying the image effect (Block 540).

The terminology used in this application with respect to network architecture is meant to include all client/server environments. Therefore it is manifestly intended that this invention be limited only by the following claims and equivalents thereof.
