DESCRIPTION OF EMBODIMENTS

1. Configuration of Projector According to First Embodiment

FIG.1is a block diagram showing a configuration of a projector100as a display device.

The configuration of the projector100will be described with reference toFIG.1.

The projector100includes an operation unit110, an operation signal receiver120, an image input interface130, a frame memory140, an image processor150, an image projection unit160, and a PJ controller170. Hereinafter, the interface is abbreviated as an I/F.

The operation unit110includes a plurality of operation keys. A user inputs various instructions to the projector100by operating the operation keys of the operation unit110. When the user operates the operation key of the operation unit110, the operation unit110outputs, to the PJ controller170, an operation signal corresponding to the operated operation key. The operation keys of the operation unit110include a power key for switching power on and off, a menu key for displaying a menu for performing various settings, a direction key for selecting a menu item, and an enter key for determining an operation.

The operation signal receiver120is a receiving device for an infrared signal, and includes a light receiving element, a decoder, and the like (not shown). The operation signal receiver120receives and decodes an infrared signal transmitted from a remote control10. The operation signal receiver120decodes the infrared signal and outputs, to the PJ controller170, an operation signal corresponding to the operated operation key or button on the remote control10. The operation signal receiver120may receive a wireless signal by Bluetooth or the like from the remote control10. Bluetooth is a registered trademark. When a wireless signal is received, the operation signal receiver120may include an antenna and a reception circuit. The operation unit110and the operation signal receiver120can also be referred to as an operation input I/F.

The remote control10includes a plurality of operation keys similar to those of the operation unit110. For example, the remote control10includes a menu key for displaying a menu for performing various settings, direction keys corresponding to four directions, upper, lower, left, and right, for selecting a menu item, and an enter key for determining an operation. The remote control10also includes a combination button for instructing a combination of the decoration image300or for instructing cancellation of a combination. When the combination button is turned on, the projector100combines the decoration image300with an input image supplied from an information processing device50to generate a composite image400, and displays the generated composite image400on a screen30. When the combination button is turned off, the projector100displays an input image supplied from the information processing device50on the screen30. The remote control10may be a mobile terminal such as a smartphone. In this case, an I/F image of the operation key is displayed on a touch panel of the mobile terminal by application software installed in the mobile terminal.

An image input I/F130includes a connector and an interface circuit, and is wired to the information processing device50via a cable55. The information processing device50is an external device that supplies an image signal to the projector100, and for example, a desktop personal computer, a notebook personal computer, a tablet personal computer, or a smartphone is used. The image input I/F130extracts an input image in the image signal received via the cable55, and outputs the extracted input image to the image processor150. As the image input I/F130, for example, a high-definition multimedia interface (HDMI) is used. HDMI is a registered trademark. In the embodiment, a case will be described in which a coupling form between the information processing device50and the projector100is wired, but the coupling form between the information processing device50and the projector100may be wireless.

The frame memory140is coupled to the image processor150. The image processor150includes an on screen display (OSD) processor155.

The image processor150loads the input image input from the information processing device50into the frame memory140.

The OSD processor155superimposes an OSD image on the input image loaded into the frame memory140under control of the PJ controller170. The OSD processor155includes an OSD memory (not shown). The OSD memory stores OSD image information representing figures, fonts, and the like for forming the OSD image. When the OSD processor155is instructed by the PJ controller170to superimpose an OSD image, the OSD processor155reads necessary OSD image information from the OSD memory and superimposes the OSD image on an input image loaded into the frame memory140.

The image processor150performs, for example, an image process on the image loaded into the frame memory140, such as a resolution conversion process, a resizing process, distortion aberration correction, a shape correction process, a digital zoom process, and adjustment of hue or luminance of the image. The image loaded into the frame memory140is an input image or an image in which an OSD image is superimposed on the input image.

The image processor150outputs image information, which is information on the image loaded into the frame memory140, to a panel driver167of the image projection unit160.

The frame memory140and the image processor150are implemented with an integrated circuit, for example. The integrated circuit includes a large scale integrated circuit (LSI), an application specific integrated circuit (ASIC), a programmable logic device (PLD), a field-programmable gate array (FPGA), a system-on-a-chip (SoC), and the like. The frame memory140and the image processor150may include an analog circuit as a part of a configuration of the integrated circuit, or may have a configuration in which the PJ controller170and the integrated circuit are combined.

The image projection unit160includes a light source161, three liquid crystal panels163R,163G, and163B as a light modulation device, a projection lens165as an optical system unit, and the panel driver167. Hereinafter, the liquid crystal panels163R,163G, and163B are collectively referred to as a liquid crystal panel163. The liquid crystal panel163corresponds to a display panel. The light source161, the liquid crystal panels163R,163G, and163B, and the projection lens165in the image projection unit160correspond to an optical device.

The light source161includes a solid-state light source such as a light-emitting diode or a semiconductor laser. As the light source161, a discharge type light source lamp such as an ultra-high pressure mercury lamp or a metal halide lamp may be used. A light emitted from the light source161according to an instruction from the PJ controller170is converted into a light having a substantially uniform luminance distribution by an integrator optical system (not shown), and is separated into color light components of red (R), green (G), and blue (B) that are three primary colors of lights by a color separation optical system (not shown). Thereafter, the light separated into the color light components of red (R), green (G), and blue (B) is respectively incident on the liquid crystal panels163R,163G, and163B. The light separated into the color light components incident on the liquid crystal panels163R,163G, and163B is referred to as a color light.

Each of the liquid crystal panels163R,163G, and163B is implemented with a transmissive liquid crystal panel in which liquid crystal is sealed between a pair of transparent substrates. In each liquid crystal panel163, rectangular image forming regions164R,164G, and164B including a plurality of pixels arranged in a matrix are formed, and a drive voltage can be applied to each pixel.

The panel driver167forms images in the image forming regions164R,164G, and164B of the liquid crystal panels163R,163G, and163B. Specifically, in accordance with an instruction from the PJ controller170, the panel driver167applies a drive voltage corresponding to image information input from the image processor150to each pixel of the image forming regions164R,164G, and164B, and sets each pixel to light transmittance corresponding to the image information. A light emitted from the light source161is transmitted through the image forming regions164R,164G, and164B of the liquid crystal panels163R,163G, and163B to be modulated for each pixel, and an image light corresponding to the image information is formed for each color light. The formed image lights with each color are combined for each pixel by a color composition optical system (not shown) to become an image light representing a color image, and are enlarged and projected on the screen30which is a projection surface by the projection lens165. In the embodiment, a case where the projection surface is the screen30is shown, but it is also possible to use an indoor wall surface, a ceiling, an outdoor outer wall, or the like as the projection surface.

The PJ controller170includes a PJ storage171and a PJ processor173.

The PJ storage171includes a volatile storage device and a nonvolatile storage device.

The volatile storage device includes, for example, a random access memory (RAM). The nonvolatile storage device is implemented with, for example, a read only memory (ROM), a flash memory, and an electrically erasable programmable read-only memory (EEPROM).

The volatile storage device is used as a calculation area for the PJ processor173.

The nonvolatile storage device stores a control program executed by the PJ processor173, a plurality of decoration images300, partial images250, and disposition information. Details of the decoration image300and the disposition information will be described later with reference toFIG.3. The partial image250is a part image obtained by dividing the decoration image300into a plurality of parts. In other words, the decoration image300is divided into a plurality of regions, and the partial image250is an image of each portion of the decoration image300divided into a plurality of regions. The decoration image300is generated by combining the partial images250. The PJ storage171stores the partial image250for each of the plurality of decoration images300. The partial image250will be described with reference toFIG.8.

The PJ processor173is an arithmetic processing device including a processor such as a central processing unit (CPU) or a micro-processing unit (MPU). The PJ processor173may be implemented with a single processor, or may be implemented with a plurality of processors. The PJ processor173may be implemented with an SoC integrated with part or all of the PJ storage171or other circuits. The PJ processor173may be implemented with a combination of a CPU that executes a program and a digital signal processor (DSP) that executes a predetermined arithmetic process. Further, all functions of the PJ processor173may be implemented in hardware, or a programmable device may be used.

2. Display of Composite Image by Projector According to First Embodiment

In the following description, the projector100projecting an image light onto the screen30to form an image on the screen30is referred to as a display. The image displayed on the screen30by the projector100is referred to as a projection image. An input image in an image signal received by the projector100from the information processing device50is referred to as a content image200. In the following description, a case where the user operates the remote control10to cause the projector100to execute a process will be described, but a similar process can be executed by the projector100by operating the operation unit110. The content image200corresponds to a first image.

The projector100generates the composite image400by combining the decoration image300with the content image200in the image signal received from the information processing device50. The projector100displays, on the screen30, an image light based on the generated composite image400. The decoration image300corresponds to a second image.

FIG.2is a diagram showing an example of the content image200.FIG.3is a diagram showing an example of the decoration image300.FIG.4is a diagram showing an example of the composite image400.

The content image200is an image in the image signal supplied from the information processing device50to the projector100as described above, and may be a moving image or a still image.

In the description forFIGS.2to4, a case where the decoration image300is combined with the content image200to generate the composite image400will be described. An operation of selecting the partial image250to be disposed in the decoration image300by an operation of the user will be described later.

The decoration image300is, for example, an image stored in advance in the PJ storage171of the projector100, and can be combined with various content images200. The decoration image300may be stored in the PJ storage171as a so-called template. The projector100may store a plurality of decoration images300in the PJ storage171. The projector100may download the decoration image300from a server device (not shown), for example. The projector100may be configured to read, from an external storage device, the decoration image300stored in the storage device such as a universal serial bus (USB) memory or an SD card and use the decoration image300.

The decoration image300is, for example, a rectangular image, and includes a disposition portion310and a frame330.

The disposition portion310is located at a center of the decoration image300, and the frame330is disposed along an outline of the disposition portion310over an entire periphery of the disposition portion310. The disposition portion310is a region in which the content image200is disposed when the composite image400is generated. The image processor150superimposes the content image200on the disposition portion310of the decoration image300loaded into the frame memory140. At this time, the frame330is disposed along an outline of the content image200outside the content image200.

The frame330is a region in which a decoration image for decorating the content image200disposed in the disposition portion310is formed. An image formed at the frame330is different for each of a plurality of decoration images300. That is, the plurality of decoration images300have different appearances.

FIG.3shows an example of the decoration image300in which the frame330is formed around an entire periphery of the decoration image300, but the frame330may be formed at any one side, two sides, or three sides of upper and lower sides, left and right sides, and the upper, lower, left, and right sides of the rectangular decoration image300.

The disposition information is information indicating a position and a range in which the content image200is disposed inside the decoration image300. The disposition information includes starting point information, and width and height information.

For example, a coordinate system is set for the decoration image300.FIG.3shows a coordinate system in which an upper left vertex O of the decoration image300is an origin, a horizontal coordinate of the decoration image300is an M-axis, and a vertical coordinate is an N-axis. Hereinafter, the coordinate system set in the decoration image300is described as an MN coordinate system.

The starting point information is coordinate information indicating a position of a starting point serving as a reference when the content image200is disposed in the disposition portion310. In the embodiment, an upper left vertex U of the disposition portion310is set as a starting point when viewed in the drawing. Coordinates of the vertex U in the MN coordinate system are denoted as (M1, N1).

The width information is information indicating a width W in an M-axis direction from the vertex U as the starting point. The height information is information indicating a height H in an N-axis direction from the vertex U as the starting point.

When the decoration image300to be combined with the content image200is selected by an operation on the remote control10by the user, the PJ controller170reads the selected decoration image300and disposition information on the decoration image300from the PJ storage171. The PJ controller170outputs the read decoration image300and disposition information to the image processor150.

When the decoration image300and the disposition information are input from the PJ controller170, the image processor150loads the input decoration image300into the frame memory140.

Next, the image processor150executes a reduction process. The image processor150executes the reduction process of reducing the content image200input from the image input I/F130in accordance with a size of the disposition portion310.

First, the image processor150compares resolution of the content image200input from the image input I/F130with width and height information in the disposition information to calculate a reduction ratio at which the content image200is reduced. As an example, the reduction ratio is a ratio of resolution corresponding to the width W and the height H to the resolution of the content image200, but a calculation method is not limited to this example.

After determining the reduction ratio, the image processor150executes a reduction process of reducing the content image200at the determined reduction ratio.

Next, the image processor150executes a combination process.

FIG.4shows the composite image400loaded into the frame memory140. The composite image400shown in FIG.4is an example in which an image process such as shape correction is not performed by the image processor150.

For example, a coordinate system is set in the frame memory140.FIG.4shows, when viewed in the drawing, a coordinate system in which an upper left vertex O of the frame memory140is set as an origin, a horizontal coordinate of the frame memory140is an S axis, and a vertical coordinate is a T axis. In the following description, the coordinate system set in the frame memory140is described as an ST coordinate system.

The image processor150generates the composite image400in the frame memory140by superimposing the content image200reduced by the reduction process on the decoration image300. The image processor150generates the composite image400having a size equal to or smaller than a maximum size of an image that can be loaded into the frame memory140in order to store the entire composite image400in the frame memory140. The maximum size of the image that can be loaded into the frame memory140is the same as a maximum size of an image that can be drawn in the image forming region164of the liquid crystal panel163.

InFIG.4, coordinates of an upper left vertex V of the decoration image300loaded into the frame memory140are assumed to be (S0, T0). The image processor150calculates a coordinate value S1by adding the coordinate value M1in an M coordinate of the starting point information in the disposition information to S0, which is an S coordinate value of the upper left vertex V of the decoration image300, as the S coordinate value of the vertex U in the ST coordinate system.

Similarly, the image processor150calculates a coordinate value T1by adding the coordinate value N1in an N coordinate of the starting point information in the disposition information to TO, which is a T coordinate value of the upper left vertex V of the decoration image300, as the T coordinate value of the vertex U in the ST coordinate system.

Next, based on the disposition information and the coordinate values of the vertex U in the ST coordinate system, the image processor150superimposes the content image200reduced by the reduction process on the disposition portion310of the decoration image300loaded into the frame memory140.

The image processor150generates the composite image400by superimposing the content image200on the disposition portion310of the decoration image300loaded into the frame memory140such that an upper left vertex of the content image200is located at the coordinates of the vertex U in the ST coordinate system. An image of the disposition portion310of the decoration image300loaded into the frame memory140before the content image200is superimposed is rewritten to the content image200.

Accordingly, the content image200is loaded into a region of the frame memory140into which the disposition portion310of the decoration image300is loaded, and an image of the frame330is left in the frame memory140as it is. In the process, the composite image400is generated so that the disposition portion310of the decoration image300as the second image does not overlap the content image200as the first image.

After generating the composite image400, the image processor150may perform, for example, an image process such as a resolution conversion process, a resizing process, distortion aberration correction, a shape correction process, a digital zoom process, and adjustment of hue or luminance of an image on the generated composite image400. These image processes are not essential processes, and the image processor150may not execute the above image process. The image processor150may execute a combination of a plurality of image processes among the above image processes.

When the image process is ended, the image processor150reads the image information on the composite image400loaded into the frame memory140, and outputs the read image information to the panel driver167of the image projection unit160.

When the image information is input from the image processor150, the image projection unit160applies a drive voltage corresponding to the input image information to each pixel of the image forming regions164R,164G, and164B, and sets each pixel to light transmittance corresponding to the image information. A light emitted from the light source161is separated into R, G, and B color lights by the color separation optical system, and passes through the image forming regions164R,164G, and164B of the liquid crystal panels163R,163G, and163B. Accordingly, the color light is modulated for each pixel, and an image light corresponding to the image information is formed for each color light. The formed image lights with each color are combined for each pixel by a color composition optical system (not shown) to become an image light representing a color image, and is enlarged and projected on the screen30which is a projection surface by the projection lens165. At this time, the composite image400displayed on the screen30is displayed on the screen30such that the frame330of the decoration image300and the content image200do not overlap.

3. Decoration Image Selection Method by Projector According to First Embodiment

Next, a selection method for selecting the decoration image300to be combined with the content image200will be described. The projector100has two modes, a preset mode and a partial image selection mode as a selection mode for selecting the decoration image300to be combined with the content image200.

The preset mode corresponds to a first method, and is a mode in which the user selects the decoration image300from a plurality of decoration images300prepared in advance.

The partial image selection mode corresponds to a second method, and is a mode in which the decoration image300is divided into a plurality of regions and the user selects an image to be displayed in each of the divided regions. An image displayed in the divided region is the partial image250.

FIG.5is a diagram showing an example of a mode selection image210displayed on the screen30.

For example, it is assumed that the combination button on the remote control10is turned on and an instruction to display the composite image400is input to the PJ controller170. When the instruction to display the composite image400is input, the PJ controller170displays the mode selection image210shown inFIG.5on the screen30. The mode selection image210corresponds to a second user interface image.

A selection image211and a selection image213are displayed in the mode selection image210.

The selection image211is an image for selecting the preset mode. The selection image213is an image for selecting the partial image selection mode. As shown inFIG.5, in the selection image211, the preset mode is displayed in text, and in the selection image213, the partial image selection mode is displayed in text.

In the mode selection image210, a selection frame215indicated by a broken line is displayed in addition to the selection image211and the selection image213. The selection frame215is an image indicating which selection button of the selection image211and the selection image213is in a selected state. The selection frame215is displayed so as to surround a periphery of the selection image211or the selection image213.

A display position of the selection frame215in the mode selection image210is changed by operating a right direction key or a left direction key on the remote control10. When the right direction key on the remote control10is pressed while the selection frame215surrounds the selection image211, the PJ controller170changes a display of the mode selection image210so that the selection frame215surrounds the selection image213. When the left direction key on the remote control10is pressed in a display state where the selection frame215surrounds the selection image213, the PJ controller170changes the display of the mode selection image210so that the selection frame215surrounds the selection image211.

FIG.6is a diagram showing an example of a first selection image220displayed on the screen30. The first selection image220corresponds to a first user interface image.

The first selection image220is an image displayed on the screen30when the enter key on the remote control10is pressed and the preset mode is selected, in a state where the selection frame215surrounds the periphery of the selection image211.

When the enter key on the remote control10is pressed, the PJ controller170changes a display of the screen30from the mode selection image210shown inFIG.5to the first selection image220shown inFIG.6.

A plurality of preset images230are displayed in the first selection image220. Any two of the plurality of preset images230respectively correspond to an image indicating a first combination or an image indicating a second combination.

The preset image230is a reduced image obtained by reducing the decoration image300, and may be generated by the PJ controller170based on the decoration image300or may be stored in the PJ storage171in advance. In the first selection image220shown inFIG.6, four preset images230, a first preset image230A, a second preset image230B, a third preset image230C, and a fourth preset image230D, are displayed. The number of preset images230displayed in the first selection image220is not limited to four, and may be less than four or more than four. When a plurality of preset images230are displayed on the first selection image220and cannot be displayed on one screen, five or more preset230may be displayed by displaying the first selection image220in a horizontally scrollable or vertically scrollable manner.

The first preset image230A, the second preset image230B, the third preset image230C, and the fourth preset image230D shown inFIG.6are images in which patterns of displayed images are different from each other. Accordingly, when a different preset image230is selected from the first selection image220, an image of the first selected preset image230is different from an image of the second selected preset image230. This means that an image selected as the image indicating the first combination and an image selected as the image indicating the second combination are different images.

In addition, the first preset image230A, the second preset image230B, the third preset image230C, and the fourth preset image230D may have different colors or may have at least one of different colors or patterns for each preset image230. The first preset image230A, the second preset image230B, the third preset image230C, and the fourth preset image230D may have different shapes, such as widths and outlines, of the preset images230. That is, the preset images230have different appearances.

FIG.7is an enlarged view of the first preset image230A.

The decoration image300can also be referred to as an image generated by combining a plurality of partial images250. The same applies to the preset image230which is a reduced image of the decoration image300. That is, the decoration image300can be said to be an image in which the partial images250, which are part images constituting the plurality of decoration images300, are selected in advance and the pre-selected partial images250are combined.

FIG.7shows a state where the first preset image230A is divided into eight regions, a first region231, a second region232, a third region233, a fourth region234, a fifth region235, a sixth region236, a seventh region237, and an eighth region238, by broken lines. As shown inFIG.7, the first region231, the second region232, the third region233, the fourth region234, the fifth region235, the sixth region236, the seventh region237, and the eighth region238do not overlap each other.

One partial image250selected from a plurality of candidate images corresponding to the plurality of partial images250is disposed one by one in each of the regions231to238of the first preset image230A divided into eight. The plurality of partial images250correspond to the plurality of candidate images. The partial image250displayed in any one of the regions231to238corresponds to a first partial image. The partial image250displayed in another one of the regions231to238corresponds to a second partial image. A plurality of candidate images that are candidates for the first partial image correspond to a plurality of first candidate images. A plurality of candidate images that are candidates for the second partial image correspond to a plurality of second candidate images. The plurality of first candidate images and the plurality of second candidate images may be the same or different.

For example, in the first region231, the second region232, the third region233, and the fourth region234in the first preset image230A, an image in which a star-shaped figure is displayed is selected in advance as the partial image250. In the fifth region235and the sixth region236, an image in which a plurality of triangular figures are displayed is selected in advance as the partial image250. In the seventh region237, an image in which a plurality of rectangular figures are displayed is selected in advance as the partial image250. In the eighth region238, an image in which a plurality of circular figures are displayed is selected in advance as the partial image250. Accordingly, a combination of the partial images250selected in the first region231to the eighth region238includes one of the plurality of first candidate images and one of the plurality of second candidate images, and corresponds to the first combination or the second combination.

AlthoughFIG.7shows the first preset image230A, the same applies to the second preset image230B, the third preset image230C, and the fourth preset image230D.

In the second preset image230B, the third preset image230C, and the fourth preset image230D as well, one partial image250selected from the plurality of partial images250stored in the PJ storage171is disposed in each of the first region231to the eighth region238. Accordingly, the first combination or the second combination is formed. The plurality of partial images250stored in the PJ storage171correspond to the plurality of candidate images.

AlthoughFIG.6shows an example in which images having different patterns are displayed as the preset image230, the images displayed as the preset image230may be images having the same color and the same pattern, and having different pattern dispositions. In other words, two preset images230having different pattern dispositions have different dispositions of candidate images. For example, it is assumed that the first preset image230A is an image in which star-shaped figures are disposed in the first region231, the second region232, the third region233, and the fourth region234, and triangular figures are disposed in the fifth region235, the sixth region236, the seventh region237, and the eighth region238. At this time, the second preset image230B may be an image in which triangular figures are disposed in the first region231, the second region232, the third region233, and the fourth region234, and star-shaped figures are disposed in the fifth region235, the sixth region236, the seventh region237, and the eighth region238.

Returning toFIG.6, the description of the first selection image220will be continued.

The selection frame225is displayed in the first selection image220.

The selection frame225is displayed to surround a periphery of any one of the first preset image230A to the fourth preset image230D. A display position of the selection frame225in the first selection image220is changed by operating any one of the upper, lower, left, and right direction keys provided on the remote control10.FIG.6shows a state where the selection frame225surrounds the periphery of the first preset image230A.

When the enter key provided on the remote control10is pressed in a state where any one of the first preset image230A to the fourth preset image230D is surrounded by the selection frame225, the PJ controller170determines that the preset image230whose periphery is surrounded by the selection frame225is selected.

In a state where the selection frame225surrounds any one of the first preset image230A to the fourth preset image230D, an operation of pressing the enter key provided on the remote control10corresponds to an operation of selecting an image indicating the first combination, and the selected preset image230corresponds to the image indicating the first combination. The operation of selecting the preset image230may be another known selection operation, and a display for indicating the selected preset image230may be an expression other than the selection frame225. Acquiring an operation signal from the remote control10or the like by the PJ controller170corresponds to receiving an operation.

When the enter key is pressed and the preset image230is selected, the PJ controller170reads, from the PJ storage171, the decoration image300that is a source of the preset image230and the disposition information, and outputs the read decoration image300and disposition information to the image processor150.

The image processor150loads the decoration image300input from the PJ controller170into the frame memory140, and executes a reduction process of reducing the content image200input from the image input I/F130in accordance with the size of the disposition portion310based on the disposition information.

Next, the image processor150loads the content image200subjected to the reduction process on the disposition portion310of the decoration image300loaded into the frame memory140to generate the composite image400. Accordingly, the image of the disposition portion310is rewritten to the content image200. Thereafter, the image processor150performs an image process such as a resolution conversion process, a resizing process, and a shape correction process on the composite image400, and outputs image information on the composite image400after the image process to the image projection unit160. The image projection unit160generates an image light corresponding to the input image information and projects the generated image light onto the screen30, so that the composite image400is displayed on the screen30.

FIG.8is a diagram showing an example of a second selection image240displayed on the screen30. The second selection image240corresponds to the first user interface image. The second selection image240is an image displayed on the screen30when the enter key on the remote control10is pressed, in a state where the selection frame215surrounds the periphery of the selection image213.

Next, an operation when the selection image213shown inFIG.5is selected and the partial image selection mode is selected will be described. When the enter key on the remote control10is pressed, the PJ controller170changes a display of the screen30from the mode selection image210shown inFIG.5to the second selection image240shown inFIG.8.

A plurality of partial images250are displayed in the second selection image240.FIG.8shows an example in which eight partial images250are displayed. The eight partial images250are respectively displayed in eight regions260obtained by dividing the decoration image300into eight regions. The eight regions260include a first region261, a second region262, a third region263, a fourth region264, a fifth region265, a sixth region266, a seventh region267, and an eighth region268. As shown inFIG.8, the first region261, the second region262, the third region263, the fourth region264, the fifth region265, the sixth region266, the seventh region267, and the eighth region268are regions that do not overlap the other regions260.

The partial image250displayed in the first region261is referred to as a partial image251in the first region261. The partial image250displayed in the second region262is referred to as a partial image252in the second region262. The partial image250displayed in the third region263is referred to as a partial image253in the third region263. The partial image250displayed in the fourth region264is referred to as a partial image254in the fourth region264. The partial image250displayed in the fifth region265is referred to as a partial image255in the fifth region265. The partial image250displayed in the sixth region266is referred to as a partial image256in the sixth region266. The partial image250displayed in the seventh region267is referred to as a partial image257in the seventh region267. The partial image250displayed in the eighth region268is referred to as a partial image258in the eighth region268.

The partial images250displayed in the respective regions260of the first region261to the eighth region268can be changed individually by an operation of the user. The user can change the partial image250displayed in each region260by operating the remote control10.

A selection frame245, a left arrow image246, and a right arrow image247indicated by broken lines are displayed in the second selection image240. First, the user operates the direction key on the remote control10to move the selection frame245to the region260where the user wants to change the partial image250.FIG.8shows a state where the first region261is surrounded by the selection frame245and the first region261is selected. When the user moves the selection frame245to the region260where the user wants to change the partial image250, the user presses the enter key on the remote control10. When the enter key on the remote control10is pressed, the PJ controller170determines that the region260surrounded by the selection frame245is selected, and displays the left arrow image246and the right arrow image247in the selected region260.

The left arrow image246and the right arrow image247indicate directions in which the projector100receives an operation by the direction key on the remote control10. The left arrow image246indicates that the projector100receives an operation of the left direction key. The right arrow image247indicates that the projector100receives an operation of the right direction key on the remote control10.

When the user presses the right direction key or the left direction key on the remote control10, the partial image251in the first region261displayed in the first region261is changed. The PJ controller170changes the partial image251in the first region261every time an operation of the right direction key or the left direction key on the remote control10is received.

The PJ storage171stores setting data indicating a display order of the plurality of partial images250. Every time the right direction key or the left direction key on the remote control10is pressed, the PJ controller170selects one of the partial images250according to the setting data, and displays, in the first region261, the selected partial image250as the partial image251in the first region261.

FIG.9is a diagram showing the partial image251in the first region261after a change.

When the partial image251in the first region261to be displayed is displayed in the first region261, the user presses the enter key on the remote control10. When the enter key is pressed, the PJ controller170becomes ready to receive an operation to move the selection frame245from the first region261.

The partial image251in the first region261to the partial image258in the eighth region268displayed in each region260, which is the first region261to the eighth region268, and the selection frame245correspond to images for receiving an operation of selecting one of the plurality of first candidate images as a candidate for the first partial image and an operation of selecting one of the plurality of second candidate images as a candidate for the second partial image.

With respect to the second region262to the eighth region268, the user performs a similar operation as in the case of the first region261to display the partial image250selected by the user in each region260, which is the first region261to the eighth region268.

When the selected partial image250is displayed in the first region261to the eighth region268, the user inputs a predetermined operation set in advance to the remote control10. The predetermined operation may be an operation of another button provided on the remote control10or a long press operation of the enter key. In the embodiment, a case where the predetermined operation is a long press operation of the enter key will be described.

When the PJ controller170receives the long press operation of the enter key, the PJ controller170outputs, to the image processor150, the selected partial image250in each region260, coordinate information indicating coordinates of the frame memory140in which the partial image250is disposed, and disposition information.

In the second selection image240, the partial images250read from the PJ storage171and displayed in the first region261to the eighth region268before a predetermined operation is input correspond to the first candidate image and the second candidate image.

In the second selection image240, the partial images250displayed in the first region261to the eighth region268when a predetermined operation is input correspond to the first partial image and the second partial image.

The image processor150loads the plurality of partial images250input from the PJ controller170into the frame memory140according to the coordinate information. Thereafter, the image processor150executes a reduction process of reducing the content image200input from the image input I/F130in accordance with the size of the disposition portion310based on the disposition information.

Next, the image processor150loads the content image200subjected to the reduction process on the disposition portion310of the decoration image300loaded into the frame memory140to generate the composite image400. Accordingly, the image of the disposition portion310is rewritten to the content image200.

Thereafter, the image processor150performs an image process such as a resolution conversion process, a resizing process, and a shape correction process on the composite image400, and outputs image information on the composite image400after the image process to the image projection unit160. The image projection unit160generates an image light corresponding to the input image information and projects the generated image light onto the screen30, so that the composite image400is displayed on the screen30.

AlthoughFIGS.7to9show an example in which the decoration image300is divided into eight regions, the first region261to the eighth region268, the number of divisions of the decoration image300may be other than eight.

FIG.10is a diagram showing another example of the second selection image240displayed on the screen30.

The second selection image240shown inFIG.10shows an example in which the decoration image300is divided into two regions260, the first region261and the second region262.

The first region261is a region for selecting the partial image250disposed at an upper side of the content image200displayed on the screen30and at a left side of the content image200toward the screen30, when the decoration image300is combined with the content image200and displayed on the screen30. The second region262is a region for selecting the partial image250disposed at a lower side of the content image200displayed on the screen30and at a right side of the content image200toward the screen30, when the decoration image300is combined with the content image200and displayed on the screen30. In the example inFIG.10as well, the first region261and the second region262do not overlap.

When the decoration image300is divided into two regions260, the first region261and the second region262shown inFIG.10, the partial image250having a shape corresponding to shapes of the first region261and the second region262may be stored in the PJ storage171in advance. That is, an image obtained by combining the partial images250disposed in the first region261, the third region263, the fifth region265, and the seventh region267shown inFIG.8is stored in the PJ storage171as the partial image250corresponding to the first region261. Similarly, an image obtained by combining the partial images250disposed in the second region262, the fourth region264, the sixth region266, and the eighth region268shown inFIG.8is stored in the PJ storage171as the partial image250corresponding to the second region262.

When the second selection image240shown inFIG.10is displayed on the screen30, the PJ controller170may combine the partial images250in the first region261to the eighth region268shown inFIG.8to generate the partial image250corresponding to the shape of the first region261shown inFIG.10. The same applies to the second region262.

FIG.11is a diagram showing another example of the second selection image240displayed on the screen30.

The second selection image240shown inFIG.11shows an example in which the decoration image300is divided into three regions260, the first region261, the second region262, and the third region263.

The first region261is a region for selecting the partial image250disposed at the upper side of the content image200displayed on the screen30, when the decoration image300is combined with the content image200and displayed on the screen30.

The second region262is a region for selecting the partial image250disposed at the lower side of the content image200displayed on the screen30, when the decoration image300is combined with the content image200and displayed on the screen30.

The third region263is a region for selecting the partial images250displayed at a left side and a right side of the content image200displayed on the screen30, when the decoration image300is combined with the content image200and displayed on the screen30.

When the second selection image240shown inFIG.11is displayed on the screen30as well, the partial images250corresponding to shapes of the first region261, the second region262, and the third region263may be stored in the PJ storage171in advance. When the second selection image240shown inFIG.11is displayed on the screen30, the partial images250in the first region261to the eighth region268shown inFIG.8may be combined to generate the partial image250corresponding to the shape of the first region261shown inFIG.11.

FIG.12is a diagram showing another example of the second selection image240displayed on the screen30.

The second selection image240shown inFIG.12also shows an example in which the decoration image300is divided into three regions260, the first region261, the second region262, and the third region263.

The first region261is a region for selecting the partial image250disposed at the left side of the content image200displayed on the screen30, when the decoration image300is combined with the content image200and displayed on the screen30.

The second region262is a region for selecting the partial image250disposed at the right side of the content image200displayed on the screen30, when the decoration image300is combined with the content image200and displayed on the screen30.

The third region263is a region for selecting the partial images250disposed at the upper side and the lower side of the content image200displayed on the screen30, when the decoration image300is combined with the content image200and displayed on the screen30.

When the second selection image240shown inFIG.12is displayed on the screen30as well, the partial images250corresponding to shapes of the first region261, the second region262, and the third region263may be stored in the PJ storage171in advance. When the second selection image240shown inFIG.12is displayed on the screen30, the partial images250in the first region261to the eighth region268shown inFIG.8may be combined to generate the partial image250corresponding to the shape of the first region261shown inFIG.12.

4. Operation of Projector According to First Embodiment

FIG.13is a flowchart showing an operation of the projector100.

The operation of the projector100will be described with reference to the flowchart shown inFIG.13.

First, the PJ controller170determines whether the combination button on the remote control10is turned on and whether an instruction to display the composite image400is received from the remote control10(step S1). When the instruction to display the composite image400is not received (step S1: NO), the PJ controller170waits until the PJ controller170receives the instruction to display the composite image400.

When the PJ controller170receives the instruction to display the composite image400from the remote control10(step S1: YES), the PJ controller170displays the mode selection image210shown inFIG.5on the screen30(step S2). Next, the PJ controller170determines whether the preset mode is selected by determining whether an operation of selecting the selection image211is received from the remote control10(step S3). In step S3, when an operation of selecting the selection image211is received, the PJ controller170determines that the preset mode is selected.

When the PJ controller170determines that the preset mode is selected (step S3: YES), the PJ controller170displays the first selection image220shown inFIG.6on the screen30(step S4).

Next, the PJ controller170determines whether an operation of selecting one of the preset images230displayed in the first selection image220is received from the remote control10(step S5). In step S5, the PJ controller170determines whether any one of the first preset image230A, the second preset image230B, the third preset image230C, and the fourth preset image230D displayed in the first selection image220is selected.

Next, when the PJ controller170does not receive the operation of selecting one of the preset images230from the remote control10(step S5: NO), the PJ controller170waits until the PJ controller170receives the operation of selecting one of the preset images230from the remote control10.

When the PJ controller170receives the operation of selecting one of the preset images230from the remote control10(step S5: YES), the PJ controller170reads, from the PJ storage171, the decoration image300that is a source of the selected preset image230and disposition information. The PJ controller170outputs the read decoration image300and disposition information to the image processor150(step S6).

The image processor150loads the decoration image300input from the PJ controller170into the frame memory140according to the disposition information (step S7). Next, the image processor150performs a reduction process (step S8). The image processor150reduces the content image200input from the image input I/F130in accordance with the size of the disposition portion310based on the disposition information.

Next, the image processor150executes a combination process (step S9). The image processor150executes a combination process of loading the content image200subjected to the reduction process on the disposition portion310of the decoration image300loaded into the frame memory140to generate the composite image400.

Next, the image processor150performs an image process such as a resolution conversion process, a resizing process, and a shape correction process on the composite image400, and outputs image information on the composite image400after the image process to the image projection unit160.

The image projection unit160executes a projection process based on the input image information (step S10). The image projection unit160applies a drive voltage corresponding to the image information input from the image processor150to each pixel of the image forming regions164R,164G, and164B, and sets each pixel to light transmittance corresponding to the image information. A light emitted from the light source161is separated into R, G, and B color lights by the color separation optical system, and passes through the image forming regions164R,164G, and164B of the liquid crystal panels163R,163G, and163B. Accordingly, the color light is modulated for each pixel, and an image light corresponding to the image information is formed for each color light. The formed image lights with each color are combined for each pixel by a color composition optical system (not shown) to become an image light representing a color image, and is enlarged and projected on the screen30which is a projection surface by the projection lens165.

Next, an operation when the partial image selection mode is selected instead of the preset mode by determining whether an operation of selecting the selection image213is received by an operation of the remote control10will be described.

When an operation of selecting the selection image213is received, the PJ controller170determines that the partial image selection mode is selected instead of the preset mode (step S3: NO). In this case, the PJ controller170displays the second selection image240shown inFIG.8on the screen30(step S11).

Next, the PJ controller170determines whether an operation of selecting one of the plurality of regions260displayed in the second selection image240is received (step S12). When the PJ controller170does not receive the operation of selecting one of the plurality of displayed regions260(step S12: NO), the process proceeds to determination in step S15. The determination in step S15will be described later.

When the PJ controller170receives the operation of selecting one of the plurality of displayed regions260(step S12: YES), the PJ controller170determines whether an operation on the direction key is received (step S13). The PJ controller170determines whether any one of the left direction key and the right direction key provided on the remote control10is operated.

When the operation on the left direction key or the right direction key is not received (step S13: NO), the PJ controller170waits until the operation of the direction key is received.

When the operation on the left direction key or the right direction key is received (step S13: YES), the PJ controller170changes the partial image250displayed in the region260selected in step S12according to the operation on the direction key (step S14).

Next, the PJ controller170determines whether a predetermined operation is received (step S15). The predetermined operation is an operation indicating that selection of the partial images250displayed in the plurality of regions260in the second selection image240is ended. The predetermined operation may be, for example, a long press of the enter key or an operation of another button provided on the remote control10.

When the predetermined operation is not received (step S15: NO), the PJ controller170returns to the determination in step S12. When the predetermined operation is received (step S15: YES), the PJ controller170outputs, to the image processor150, the partial image250selected in the region260, coordinate information indicating coordinates of the frame memory140in which the partial image250is disposed, and disposition information (step S16). Thereafter, the image processor150loads the partial image250into the frame memory140according to the coordinate information (step S7), and performs a reduction process on the content image200input from the image input I/F130according to the disposition information (step S8).

Next, the image processor150executes a combination process of loading the content image200subjected to the reduction process on the disposition portion310of the decoration image300loaded into the frame memory140to generate the composite image400(step S9).

Next, the image processor150performs an image process such as a resolution conversion process, a resizing process, and a shape correction process on the composite image400, and outputs image information on the composite image400after the image process to the image projection unit160. The image projection unit160executes a projection process (step S10), and displays an image light corresponding to the image information on the screen30.

5. Second Embodiment

Next, a second embodiment will be described.

Since a configuration of the projector100according to the second embodiment is the same as that of the first embodiment, the same reference signs are used for the configuration of the projector100, and a detailed description thereof will be omitted.

In the projector100according to the second embodiment, the decoration image300is displayed in a double manner. The projector100according to the second embodiment further displays a decoration image300inside the decoration image300. In the second embodiment, the decoration image300displayed at an outer side is referred to as an outer decoration image300A, and the decoration image300displayed at an inner side is referred to as an inner decoration image300B. The inner decoration image300B corresponds to a third image.

FIG.14is a diagram showing a third selection image270. The third selection image270corresponds to a third user interface image.

A plurality of partial images280are displayed in the third selection image270shown inFIG.14.FIG.14shows an example in which eight partial images280are displayed. The eight partial images280are respectively displayed in eight regions290obtained by dividing the decoration image300into eight regions. The eight regions290include a ninth region291, a tenth region292, an eleventh region293, a twelfth region294, a thirteenth region295, a fourteenth region296, a fifteenth region297, and a sixteenth region298.

The partial image280displayed in the ninth region291is referred to as a partial image281in the ninth region291. The partial image280displayed in the tenth region292is referred to as a partial image282in the tenth region292. The partial image280displayed in the eleventh region293is referred to as a partial image283in the eleventh region293. The partial image280displayed in the twelfth region294is referred to as a partial image284in the twelfth region294. The partial image280displayed in the thirteenth region295is referred to as a partial image285in the thirteenth region295. The partial image280displayed in the fourteenth region296is referred to as a partial image286in the fourteenth region296. The partial image280displayed in the fifteenth region297is referred to as a partial image287in the fifteenth region297. The partial image280displayed in the sixteenth region298is referred to as a partial image288in the sixteenth region298.

A selection frame275, a left arrow image276, and a right arrow image277are displayed in the third selection image270. The selection frame275is an image surrounding a periphery of any one of the ninth region291to the sixteenth region298. The left arrow image276is an image indicating that the projector100receives an operation of the left direction key on the remote control10. The right arrow image277is an image indicating that the projector100receives an operation of the right direction key on the remote control10.

A method for selecting the partial image281in the ninth region291to the partial image288in the sixteenth region298displayed in the ninth region291to the sixteenth region298is the same as a method for selecting the partial image251in the first region261to the partial image258in the eighth region268described inFIG.8.

In the third selection image270, the partial images250read from the PJ storage171and displayed in the ninth region291to the sixteenth region298before a predetermined operation is input correspond to a third candidate image and a fourth candidate image.

In the third selection image270, the partial images250displayed in the ninth region291to the sixteenth region298when a predetermined operation is input correspond to the third partial image and the fourth partial image.

In the third selection image270shown inFIG.14, to simplify the diagram, the partial image251in the first region261to the partial image258in the eighth region268are not displayed, but the partial image251in the first region261to the partial image258in the eighth region268may be displayed.

The PJ controller170outputs, to the image processor150, the partial image250constituting the outer decoration image300A, the partial image250constituting the inner decoration image300B, coordinate information indicating the coordinates of the frame memory140in which the partial image250is disposed, and disposition information.

The image processor150loads the partial image250constituting the outer decoration image300A into the frame memory140according to the input coordinate information. Next, the image processor150performs a reduction process on the content image200according to the input disposition information, and disposes the content image200subjected to the reduction process at the disposition portion310of the outer decoration image300A. Further, the image processor150loads the partial image250constituting the inner decoration image300B into the frame memory140according to the input coordinate information. At this time, the image processor150loads the partial image250constituting the inner decoration image300B into the frame memory140according to the coordinate information, so that the inner decoration image300B is superimposed on at least a part of the content image200.

FIG.15shows a projection image displayed on the screen30.

The outer decoration image300A and the inner decoration image300B are displayed in the projection image. The outer decoration image300A is displayed outside the content image200along an outline of the content image200. The inner decoration image300B is displayed along the outline of the content image200so as to at least partially overlap the content image200. The inner decoration image300B may be displayed such that the entire inner decoration image300B overlaps the content image200, or may be displayed outside the content image200similarly to the outer decoration image300A.

The inner decoration image300B is displayed so as to at least partially overlap the content image200. Therefore, transmittance of the inner decoration image300B may be changed by an operation on the remote control10or the like. In the examples inFIGS.14and15, the outer decoration image300A and the inner decoration image300B do not overlap, but the outer decoration image300A and the inner decoration image300B may at least partially overlap.
