As described above, when the reading program 54G reads a file from the memory stick 116, the display program 54F sequentially displays the thumbnails 201 corresponding to the data stored in the read file. Can know the contents of the file stored in the memory stick 116 and the reading state of the file at that time.

When the reading program 54G reads a file from the memory stick 116, the display program 54F executes the requested process in response to a request for a process for the file read at that time.

Further, even if the reading of the file is slow, the display program 54F sequentially displays the thumbnails 201 corresponding to the data stored in the read file, so that the user can read the next thumbnail 201 based on the displayed thumbnail 201. Can be determined.

The thumbnail 20 in the state shown in FIG.
The processing that can be executed on the files corresponding to 1-1 to 201-3 is the thumbnail 20 in the state shown in FIG.
Executable processing for the files corresponding to 1-1 to 201-7 and the thumbnail 20 in the state shown in FIG.
This is the same as the processing that can be executed on the files corresponding to 1-1 to 201-10.

Next, the thumbnail 201 for displaying an image corresponding to voice or text data will be described. As shown on the left side of FIG. 10, conventionally, icons and the like corresponding to pre-recorded sounds have been displayed. In this case, even if a display corresponding to a plurality of audio data is displayed,
The same icon was only displayed for that number.

On the other hand, as shown on the right side of FIG. 10, the display program 54F generates an image corresponding to audio or text data itself and
Display as 01.

FIG. 11 shows the contents processing routine 152.
Is a thumbnail 2 displaying an image corresponding to audio data
FIG. 11 is a diagram illustrating a procedure for generating 01.

First, the content processing routine 152
Sets an area for displaying the thumbnail 201 in accordance with the size of the thumbnail 201 to be displayed. The content processing routine 152 divides the area displayed by the thumbnail 201 into a rectangular area composed of a predetermined number of pixels according to the size of audio data.

The content processing routine 152 extracts data of an arbitrary part (for example, when audio data is viewed as a data string, data located at the center of the data string) from the audio data, and extracts the extracted data. Based on this, a pixel value of the pixel is generated. For example, the content processing routine 152 cuts out data from audio data in units of 8 bits and regards the data as RGB data.

In the example of FIG. 11, 0fh (hereinafter, a numerical value represented by a hexadecimal number) cut out from audio data is
(H is added at the end) is R data, 7eh is G data, and 57h is B data. Similarly, 0f
In the data following h, 7eh, and 57h, 12h is R data, 25h is G data, and 98h is B data.

When the audio data is encrypted or encoded, the content processing routine 152 generates RGB data from the encrypted or encoded audio data without performing processing such as decoding. I do.

In this way, the content processing routine 152 generates the same number of pixel values as RGB data and the like as the number of divided areas of the thumbnail.

The content processing routine 152 sets RGB data in each of rectangular areas formed by dividing the area to be displayed by the thumbnail 201 and having a predetermined number of pixels. At this point, the thumbnail 201 is composed of images of different colors for each rectangle, as shown in the example of the image 1 in FIG.

The content processing routine 152 is composed of RGB
Blur processing (so-called blurring processing) is applied to the thumbnail 201 in which the data of (1) is set. By blurring the thumbnail 201 in which RGB data is set,
As shown in the example of the image 2 in FIG. 11, there is an effect that the displayed thumbnail 201 is easy to see.

Thumbnail 2 in which RGB data is set
The processing to be added to 01 is not limited to the blur processing, and may be any image processing such as embossing and contour extraction.

The content processing routine 152 further includes
Attribute data such as a title, an artist name, or a reproduction time included in the audio file is overwritten with a text at a predetermined position, as shown in an image 3 in FIG.

Since the content processing routine 152 overwrites attribute data such as title, artist name, or reproduction time included in the audio file with text, the user who has viewed the thumbnail 201 corresponding to the audio data Can know the contents of the audio data corresponding to the thumbnail 201 in more detail.

The image to be set in the thumbnail 201 may be generated based on the spectrum of the audio data. For example, a color (for example, a color corresponding to the level of each frequency band)
-40dB corresponds to the 0-degree color in the color wheel, and 0dB corresponds to 3 in the color wheel.
(Corresponding to the color of 60 degrees) and set the thumbnail 20
An image corresponding to the elapsed time of the audio spectrum can be set in the entire thumbnail 201 by associating the vertical arrangement of 1 with the elapsed time of the audio.

As shown in FIG. 12, the content processing routine 152 divides the area for displaying the thumbnail 201 into a small number of rectangular areas when the audio data is small, and displays the thumbnail 201 when the audio data is large. Is divided into a number of rectangular areas.

In this way, the user of the personal computer 1 can predict the size of the audio data only by looking at the thumbnail 201 corresponding to the audio data.

As shown in FIG. 13, the content processing routine 152 executes the processing of the thumbnail 20 corresponding to the audio data.
The thumbnail 201 is generated based on the text data in the same procedure as the procedure for generating the thumbnail 201. In this case, the content processing routine 152 extracts a text at a predetermined point of the text included in the text data as text displayed on the content 201,
It may be displayed.

As described above, the display program 54F can generate the thumbnail 201 corresponding to audio data or text data.

Note that the display program 54F is not limited to audio data or text data, but also data not containing images, for example, HTML (Hypertext Markup Language).
The thumbnail 201 can be generated corresponding to data stored in a file, data for spreadsheet calculation, or an execution program (load module).

Next, the arrangement of the thumbnails 201 displayed by the display program 54F will be described.

Conventionally, when displaying thumbnails and information attached to the thumbnails, as shown in FIG. 14, it is common to arrange the thumbnails so as not to overlap with each other and to display the information attached to the thumbnails near the thumbnails. there were.

In contrast, the personal computer 1
The display program 54F has three types of display modes in which the thumbnails 201 are superimposed and displayed in addition to a display method (hereinafter, referred to as a square view) in which the thumbnails 201 are arranged in a grid so as not to overlap.

In the first display mode, a virtual straight line or curve (open line) is defined, and the thumbnail 201 is arranged on the virtual straight line or curve (hereinafter, referred to as a line view). In the second display mode, a virtual perfect circle or ellipse (closed line) is defined, and the thumbnail 201 is arranged on the virtual perfect circle or ellipse (hereinafter, referred to as a loop view). In the third display mode,
A virtual spiral is defined, and the virtual spiral has a thumbnail 201.
(Hereinafter referred to as a spiral view).

First, the line view displayed when the icon 202-1 is clicked will be described.
As shown in FIG. 15, the display program 54F defines an axis 221-1 consisting of a straight line or a curve, and
1, thumbnails 201-1 to 201-3 are arranged. When the thumbnail 201-1 is selected and the thumbnail 201-1 and the thumbnail 201-2 overlap, the display program 54F displays the entire thumbnail 201-1 and displays the thumbnail 201-2 of the thumbnail 201-2.
Only the portion not overlapping with 1-1 is displayed.

When the thumbnail 201-1 is selected and the thumbnails 201-1 to 201-3 are arranged in order, when the thumbnail 201-2 and the thumbnail 201-3 overlap, the display program 54F displays the thumbnail 201-1.
Only the part of the thumbnail 201-1 that does not overlap with the thumbnail 201-1 is displayed, and only the part of the thumbnail 201-3 that does not overlap with the thumbnail 201-2 is displayed.

That is, the display program 54F displays the entirety of the selected thumbnail 201, and displays the thumbnails 20 away from the selected thumbnail 201.
From 1, the thumbnail 201 near the selected thumbnail 201 is preferentially displayed (so as to be arranged at a position closer to the user).

Information associated with the data corresponding to the thumbnail 201-1, for example, the text 211-1 indicating the file name, the creation date, the size of the image, etc. The text 211-1 is arranged on the axis 221-2 at which the upper position coincides. Information attached to data corresponding to thumbnail 201-2,
For example, the text 211-2 indicating the file name or the like is arranged on the axis 221-2 at which the lower position of the thumbnail 201-2 coincides with the upper position of the text 211-2. Information accompanying the data corresponding to the thumbnail 201-3, for example, text 2 indicating a file name or the like
11-3 is arranged on the axis 221-2, for example, where the position below the thumbnail 201-3 and the position above the text 211-3 coincide.

The shaft 221-1 and the shaft 221-2
Is not displayed on the screen of the LCD 7. Hereinafter, the shaft 22
When it is not necessary to distinguish 1-1 and the shaft 221-2 individually, they are simply referred to as the shaft 221. Hereinafter, the text 211-
When it is not necessary to individually distinguish 1 to 211-3, they are simply referred to as text 211.

For example, when the horizontal direction of the screen is the x axis and the horizontal direction of the screen is the y axis, as shown in FIG.
1-1 is calculated by Expression (1), and the axis 221-2 is calculated by Expression (2).

X = sin (π / 2t) (y−c0) + c1 (1) x = −sin (π / 2t) (y−c0) + c1 (2) where x is the x axis The coordinates indicate the coordinates, and y indicates the coordinates on the y-axis. t is an elapsed time from a predetermined reference time (for example, a time corresponding to when display is started in the line view), and c0 and c1 indicate a center position of the selected thumbnail.

.Theta. Shown in FIG. 16 corresponds to .pi. / 2t in the equation (1) or (2).

Therefore, for example, based on the positions of the shaft 221-1 and the shaft 221-2 shown in FIG.
When the display is started with the arrangement of the thumbnail 201 and the text 211 shown in FIG.
The position 21-2 moves smoothly toward the position shown in FIG. 17C, and further smoothly moves toward the position shown in FIG.

That is, the thumbnail 201 and the text 211 smoothly move from the arrangement shown in FIG. 17B to the arrangement shown in FIG. 17D in response to the movement of the axes 221-1 and 221-2. Move, and then Figure 17
It moves smoothly to the arrangement shown in (F).

When the positions of the shaft 221-1 and the shaft 221-2 reach the positions shown in FIG.
It moves smoothly toward the position shown in FIG. 17C, and further smoothly moves toward the position shown in FIG.

That is, the thumbnail 201 and the text 211 smoothly move from the arrangement shown in FIG. 17F to the arrangement shown in FIG. 17D in response to the movement of the axes 221-1 and 221-2. Move, and then Figure 17
It moves smoothly to the arrangement shown in (B), and moves smoothly as described above.

Since the selected thumbnail 201 is located at the center of the movement of the axis 221-1, the thumbnail 201 selected by the user does not move, and the thumbnails 201 located above and below the selected thumbnail 201 are not moved. Since the user moves, the user can quickly and reliably recognize the selected thumbnail 201.

Next, the loop view displayed when the icon 202-2 is clicked will be described.
As shown in FIG. 18, the display program 54F includes a perfect circle,
A thumbnail 241-1 to 201-5 is arranged based on the axis 241-1 by defining an axis 241-1 formed of an ellipse or a predetermined loop (including a polygon). Thumbnail 2
When 01-3 is selected, the thumbnail 201-3 is selected.
When the thumbnail 201-2 overlaps the thumbnail 201-2, the display program 54F displays the entire thumbnail 201-3, and displays only the portion of the thumbnail 201-2 that does not overlap with the thumbnail 201-3.

When the thumbnail 201-3 is selected and the thumbnails 201-1 to 201-5 are arranged in order, when the thumbnail 201-2 and the thumbnail 201-1 overlap, the display program 54F displays the thumbnail 201-1.
Only the portion of the thumbnail 201-1 that does not overlap with the thumbnail 201-3 is displayed, and only the portion of the thumbnail 201-1 that does not overlap with the thumbnail 201-2 is displayed. Display program 54F
Displays only the portion of the thumbnail 201-4 that does not overlap with the thumbnail 201-3, and displays only the portion of the thumbnail 201-5 that does not overlap with the thumbnail 201-4.

That is, the display program 54F displays the entirety of the selected thumbnail 201, and displays the thumbnails 20 away from the selected thumbnail 201.
From 1, the thumbnail 201 near the selected thumbnail 201 is preferentially displayed (so as to be arranged at a position closer to the user).

[0138] The display program 54F defines an axis 241-2 corresponding to the axis 241-1. Thumbnail 201-
For example, the text 211-1 corresponding to the text 211-1 corresponds to the position of the center of the right and left of the thumbnail 201-1 and the text 211-1.
1 are located on the axis 241-2 where the positions of the centers coincide. Text 211- corresponding to thumbnail 201-2
2 is the axis 241 where the center position of the left and right center of the thumbnail 201-2 matches the center position of the text 211-2.
2 are arranged. Similarly, the texts 211-3 to 211-5 corresponding to the thumbnails 201-3 to 201-5 respectively are the thumbnails 201-3 to 201-5.
01-5 shows the position of the center of the left and right, and text 2

41-2.

The shaft 241-1 and the shaft 241-2
Is not displayed on the screen of the LCD 7. Hereinafter, the shaft 24
When it is not necessary to individually distinguish 1-1 and axis 241-2, they are simply referred to as axis 241.

As shown in FIG. 19, the display program 54F includes the thumbnail 201 arranged on the axis 241-1 and the text 211 arranged on the axis 241-2.
The selected thumbnail 201 is displayed on the LCD 7 as a center.

FIG. 20 shows the shaft 241-1 and the shaft 241-
Axis 241 of display program 54F when 2 is a circle
It is a figure explaining the processing which calculates -1 and axis 241-2.

Assuming that the number of thumbnails 201 to be displayed is n, the radius r of the circle corresponding to the axis 241-1 and the axis 241-2 can be obtained by equation (3).

R = 64n / 2π (3) 64 included in the equation (3) is a constant corresponding to the thumbnail interval.

Assuming that the coordinates of the center of the screen are (Xcent, Ycent), the coordinates of the center of the axis 241-1 (Xcent1, Ycent1)
Is represented by equation (4), and the coordinates (Xc
ent2, Ycent2) is represented by equation (5).

(Xcent1, Ycent1) = (Xcent, Ycent-r-64) (4) (Xcent1, Ycent1) = (Xcent, Ycent + r + 64) (5) The position of the i-th thumbnail 201 is represented by the formula ( 6).

(X1i, Y1i) = (Xcent1 + rsin (i * 2π / n), Ycent1 + rcos (i * 2π / n)) (6) The position of the i-th text 211 is obtained by Expression (7). Can be

(X2i, Y2i) = (Xcent2 + rsin (i * 2π / n), Ycent2-rcos (i * 2π / n)) (7) In the loop view, a display program corresponding to the operation of the jog dial 4 When 54F changes the arrangement of the thumbnail 201, the user can intuitively
There is an advantage that it is easy to grasp the movement of No. 1.

Next, the spiral view displayed when the icon 202-4 is clicked will be described. As shown in FIG. 21, the display program 54F defines a spiral axis 261 and, based on the axis 261, the thumbnails 201-1 to 201-3 and the text 211.
-1 to 221-3 are arranged. The axis 261 has a position in the depth direction with respect to the screen. Even if the thumbnails 201 have the same size, L
The size displayed on the CD 7 will be different.

[0149] The selected thumbnail 201 is displayed in a large size because it is arranged at the position where the distance from the screen is the shortest. The display program 54F displays the selected thumbnail 201 in a large size, and displays the non-selected thumbnail 201 smaller than the selected thumbnail 201.

Therefore, the display program 54F displays a large number of thumbnails 201 that the user is paying attention to and displays small thumbnails 201 that the user is not paying attention to while displaying a large number of thumbnails 201. Used more efficiently.

Alternatively, for example, as shown in FIG. 22A, the display program 54F defines the axes 261-1 and 261-2, which are spirals having the same axis, and sets the axis 261-1 based on the axis 261-1. , The thumbnail 201 is placed on the axis 26
The text 211 may be arranged based on 1-2.

The coordinates (x, y, z) of the axis 261 formed by a spiral having a radius of r are expressed by the following equations (8), (9), and (1).
0).

X = rsin (t) + c0t (8) y = c1t (9) z = rcos (t) (10) where r is the radius of the spiral, and c0 and c1 are the gradients of the spiral. This is a constant to be determined, and t is an arbitrary value.

As shown in FIG. 23, the coordinates (xi, yi, zi) of the thumbnail 201 arranged on the axis 261 composed of a spiral having a radius of r are represented by Expressions (11), (12), and (12). It is determined by (13).

Xi = Xcent + rsin (i * 2π / 9)-(i * r / 20) (11) yi = Ycent + (i * r / 10) (12) zi = r-rcos (i * 2π / 9) (13) Here, Xcent and Ycent indicate the coordinates of the center of the screen. The z-axis is a coordinate axis that is perpendicular to the x-axis and the y-axis and that corresponds to the depth of the screen. 20 in Expression (11) and 10 in Expression (12) are predetermined constants.

Next, the square view displayed when the icon 202-3 is clicked will be described. As shown in FIG. 24 and FIG. 25, the display program 54F, for example, as the top row of the screen, the center positions in the vertical direction coincide with each other, and the interval between the center positions in the horizontal direction becomes a predetermined distance. Like 5 thumbnails 20
1-1 to 201-5 are arranged.

In the display program 54F, as the second column of the screen, the positions of the respective centers in the vertical direction coincide with each other.
5 so that the distance between the center positions in the horizontal direction is a predetermined distance.
One thumbnail 201-6 to 201-10 is arranged. In other words, the horizontal center position of the thumbnail 201-6 matches the horizontal center position of the thumbnail 201-1, and the horizontal center position of the thumbnail 201-7 is
The horizontal center position of the thumbnail 201-2 matches the horizontal center position of the thumbnail 201-8, and the horizontal center position of the thumbnail 201-8 matches the horizontal center position of the thumbnail 201-3.
The center position in the horizontal direction of 01-9 is the thumbnail 201-4.
Of the thumbnail 201-10.
Of the display program 54F so that the horizontal center position of the thumbnail 201-5 coincides with the horizontal center position of the thumbnail 201-5.
Shows five thumbnails 201-6 in the second column of the screen.
To 201-10.

The display program 54F arranges the thumbnails 201-11 to 201-20 by the same processing as the third and fourth columns of the screen.

The display program 54F can sort the thumbnails 201 in the line view, the loop view, the spiral view, or the square view based on the creation date, shooting time, file name, image size, and the like. .

Next, the movement of the icon 202 when the icon 202 is clicked will be described. FIG.
FIG. 4 is a diagram illustrating an example of movement of an icon 202.

As shown on the right side of FIG. 26, for example, when icons 202-1 to 202-3 are arranged on the screen, when icon 202-1 is clicked, the shape or color of icon 202-1 is changed. The display program 54F changes the position of the icon 202-1 and the icon 202-2 so as to change the position of the icon 202-1 and the position of the icon 202-2.
Move 2-2.

That is, the processing manager 151 determines the position of the icon 202-1 and the icon 202-2 so that the icon 202-1 and the icon 202-2 move at a predetermined cycle when the touch pad 6 is clicked.
Is calculated.

The icon processing routine 153-1 executes the icon 2 processing based on the position calculated by the processing manager 151.
02-1 is displayed so as to be moved to the center of the screen.
The icon processing routine 153-2 is a processing manager 1
Based on the position calculated by 51, the icon 202-2 is
Display to be moved to the lower left of the screen.

The movement of the icons 202-1 to 202-3 is not limited to a linear movement, and may move on a predetermined curve. The direction of movement of the icons 202-1 to 202-3 is not limited to being on the same plane as the screen to be displayed.
The depth direction may be included with respect to the screen.

When the thumbnail 201 is displayed in the loop view, as shown in FIG. 27A, the display program 54F places the icon 202-2 at the center in the horizontal direction of the screen. When the icon 202-1 is clicked in the state shown in FIG. 27A, the display program 54F moves the icons 202-1 to 202-4 at a speed that can be visually confirmed by the user. FIG.
After the state shown in FIG. 27B, the display program 54F arranges the icon 202-1 at the center in the left-right direction of the screen as shown in FIG.

The display program 54F includes an icon 202
-2 through 202-4 are represented by icons 202-2.
To 202-4 based on the numerical values associated with each of them.

For example, the icon 202-1 is associated with 1, the icon 202-2 is associated with 2, the icon 202-3 is associated with 3, and the icon 202-2 is associated with 3.
When 4 is associated with 4, the display program 54
F arranges icons 202-2 to 202-4 from the left side of the screen in ascending numerical order.
That is, the display program 54F displays the icon 202-
2 is arranged on the left side of the screen, the icon 202-3 is arranged on the right side of the icon 202-2, and the icon 202-4 is arranged on the right side of the icon 202-3.

As described above, the display program 54F moves the icon 202 and arranges the icon 202 corresponding to the display mode, for example, at the center of the screen, so that the user can operate the icon 202. That is, it is possible to surely know that, and quickly know the display mode of the thumbnail 201.

Next, the thumbnail 201 or the icon 2
Display of an afterimage associated with the movement of 02 will be described. The content processing routine 152 is, for example, 30 times per second,
The thumbnail 202 is drawn. As shown in FIG. 28, when moving the thumbnail 202, the content processing routine 152 displays an afterimage corresponding to the previous drawing on the screen.

If the display of the afterimage is not set, the content processing routine 152 erases the current screen,
A new thumbnail 202 is drawn.

As shown in the example of FIG. 29, when the display of the afterimage is set, when the thumbnail 202 is drawn,
The content processing routine 152 sets the brightness of the previously displayed screen to, for example, 80% and renders the screen. The content processing routine 152 renders the screen in which the brightness is set to 80% so as to overwrite the thumbnail 202.

Therefore, when the thumbnail 202 is moved, the content processing routine 152 draws the image with the brightness of the previously drawn screen lowered each time the drawing is performed, so that an afterimage is displayed. By performing such processing,
The display program 54F can display an afterimage with a smaller amount of calculation.

FIG. 30 is a diagram for explaining a change in the state corresponding to the display position of the thumbnail 201 or the icon 202 when the thumbnail 201 or the icon 202 is moved. For example, in FIG. 30, state A corresponds to a loop view, and state B corresponds to a square view.

In a state A corresponding to the loop view,
When the icon 202-3 is clicked, the processing manager 151 determines that the content processing routines 152-1 to 152-N draw thumbnails 201-1 to 201-2 next.
01-N is calculated and supplied to each of the content processing routines 152-1 through 152-N.

The processing manager 151 calculates the position of the thumbnail 201 based on the transition function shown in the graph of FIG. Assuming that the distance between the position of the thumbnail 201 in the state A and the position of the thumbnail 201 in the state B is 1, the transition function is based on the elapsed time t from the start of the transition.
The distance of the thumbnail 201 at the elapsed time t from the position of the thumbnail 201 in the state B is output.

That is, assuming that the elapsed time ti, the position of the thumbnail 201 in the state A is Ai, and the position of the thumbnail 201 in the state B is Bi, the position Ci of the thumbnail 201 is calculated by equation (14).

Ci = (Ai−Bi) d (ti) + Bi (14) In the transition function where the elapsed time t is close to 0, the elapsed time t
As the distance increases, the distance d (t) decreases sharply from 1;
Thereafter, the distance d (t) is defined so as to gradually decrease to zero. By defining the transition function in this way, when the display program 54F starts moving the thumbnail 201, the display program 54F quickly moves the thumbnail 201,
The thumbnail 201 is moved slowly as it approaches the destination.

In this way, the display program 5
The 4F can quickly move the thumbnail 201 and eliminate a sense of discomfort associated with the movement of the thumbnail 201 by the user.

The transition function is not limited to the one shown in FIG. 31. For example, in a portion where the elapsed time t is close to 0, the distance d (t) gradually decreases from 1 as the elapsed time t increases. After that, the distance d (t) may suddenly decrease to zero.

The processing manager 151 calculates the position of each of the thumbnails 201-1 to 201-N corresponding to the distance d (t) based on the transition function according to the elapsed time t, and executes the content processing routine. 152-1 to 152-N
Supply to each. Content processing routine 152
-1 to 152-N are thumbnails 201-
1 to 201-N are drawn.

In the state C1 corresponding to the elapsed time t1,
Each of the thumbnails 201-1 to 201-N is displayed at an intermediate position where it moves toward the position of the thumbnails 201-1 to 201-N in the state B. Elapsed time t1
State C corresponding to elapsed time t2 after a predetermined time has elapsed from
2, the thumbnails 201-1 to 201-N further include thumbnails 201-1 to 201-2 in the state B.
It is displayed at an intermediate position where it moves toward the position 01-N.

In the state C3 corresponding to the elapsed time t3 at which the predetermined time has elapsed from the elapsed time t2, the thumbnail 201
Each of -1 to 201-N is displayed at a position closer to the position of the thumbnails 201-1 to 201-N in the state B, in the middle of the movement.

FIG. 32 shows an example of the position of the thumbnail 201 in the state C1 and the position of the thumbnail 201 in the state C2.

During the transition from the state A to the state B, for example, when an input to the effect that a transition is made to the state D is input, the state A
From the state in the middle of transition from state to state B to state D.

For example, as shown in FIG. 33, when the icon 202-4 is clicked in the state C2, the state C2 is set as a new start state, and the state changes to the state D corresponding to the spiral view. The transition from the state C2 to the state D is performed in the same manner as the transition from the state A to the state B.
This is performed via 1 to state E2.

In the spiral view, when the jog dial 4, the keyboard 5, or the touch pad 6 is being operated, and when the jog dial 4, the keyboard 5, and the touch pad 6 are not being operated, the processing manager 151 sets in FIG. As shown in the thumbnail 2
01 is changed.

Further, in the spiral view, when the keyboard 5 or the like is continuously pressed (for example, the direction key is continuously pressed), the keyboard 5 or the like is set to one.
The processing manager 151 changes the position where the thumbnail 201 is displayed, when it is pressed only once and immediately released.

More specifically, when the jog dial 4 and the keyboard 5 are not operated, for example, as shown in FIG. 35, the processing manager 151 gives the content processing routine 152 a thumbnail on a spiral having a larger radius r. 201 is displayed.

The jog dial 4 is kept being rotated.
Alternatively, when the keyboard 5 is continuously pressed, the processing manager 151 causes the content processing routine 152 to display the thumbnail 201 on a spiral having a smaller radius r, as shown in FIG. 36, for example.

When the jog dial 4 is rotated by one click or the keyboard 5 is depressed once and released immediately, the processing manager 151 sends the content processing routine 152 to the intermediate processing routine shown in FIGS. 35 and 36. The thumbnail 201 is displayed on a spiral having a radius r.

The user of the personal computer 1 can immediately determine whether or not the jog dial 4 or the keyboard 5 is operated based on the display position of the thumbnail 201.

The display program 54F may reproduce a predetermined sound or display a predetermined image together with the change of the radius r of the spiral.

When the jog dial 4 and the keyboard 5 are not operated, the processing manager 151
The thumbnail 201 may be displayed on a spiral having a smaller radius r, and when the jog dial 4 or the keyboard 5 is operated, the content processing routine 152 may display the thumbnail 201 on a spiral having a larger radius r. .

Next, the state transition when changing from the state shown in FIG. 38 to the state shown in FIG. 39, the state transition when changing from the state shown in FIG. 41 to the state shown in FIG.
The state transition when the state changes from the state shown in FIG. 4 to the state shown in FIG. 45, or the state transition when the state changes from the state shown in FIG. 47 to the state shown in FIG. 48, and the state transition shown in FIG. State transition when changing to the state shown,
The state transition when the state shown in FIG. 42 changes to the state shown in FIG. 41, the state transition when the state shown in FIG. 45 changes to the state shown in FIG. 44, or the state shown in FIG. The state transition when the state changes to the indicated state will be described.

The state transition when the state shown in FIG. 38 changes to the state shown in FIG. 39, and the state transition shown in FIG.
When the state changes from the state shown in FIG. 44 to the state shown in FIG. 45, or when the state changes from the state shown in FIG. 47 to the state shown in FIG. The state transition corresponds to a request for displaying or reproducing a desired still image, moving image, or sound by the user. Since the operation of the thumbnail 201 or the like ultimately aims to display or reproduce a still image, a moving image, or a sound, this state transition can be said to be of great importance to the user as shown in FIG.

On the other hand, from the state shown in FIG.
State transition when changing to the state shown in FIG. 8, state transition when changing from the state shown in FIG. 42 to the state shown in FIG. 41, and state when changing from the state shown in FIG. 45 to the state shown in FIG. From the state shown in FIG.
The state transition when changing to the state shown in
This is a transition to a transitional state for the purpose of ending the display or reproduction of the moving image or the sound or selecting another thumbnail 201. This state transition can be said to be of low importance to the user, as shown in FIG.

Therefore, as shown in FIG. 50, when a state transition that is important to the user is made, for example, when a desired still image, moving image, or sound is displayed or reproduced, a display program is executed. The display 54F changes the display relatively slowly at a speed at which the user can visually recognize the change in the display in order to ensure that the user recognizes the display or the reproduction.

On the other hand, when making a state transition that is less important to the user, for example, display of a desired still image, moving image, or sound is stopped, or reproduction is stopped.
When the display is changed to the display selected by the thumbnail 201, the display program 54F quickly changes the display.

As described above, the display program 54F makes the user surely recognize important state transitions and quickly executes relatively insignificant state transitions, so that the user can recognize state transitions quickly. Conflicting requirements of response can be satisfied.

Next, the display of the selected thumbnail 201 will be described. As shown in FIG. 51, when the thumbnail 201 is selected, the display program 54F displays a frame 281 on the selected thumbnail 201. When another thumbnail 201 is selected, the display program 54F deletes the frame 281 from the unselected thumbnail 201.

[0219] The display program 54F changes the brightness, saturation, or hue of the frame 281 in accordance with the passage of time. FIG. 52 is a diagram illustrating an example of a change in brightness or saturation of frame 281 corresponding to the passage of time.

For example, the display program 54F changes the brightness or the saturation of the frame 281 which is 0% linearly to 100% in 0.5 seconds, and changes the brightness or the saturation of the frame 281 which is 100%. It is changed linearly to 0% in 0.5 seconds, and this change is repeated.

The processing for changing the brightness of the frame 281 requires a smaller amount of calculation than the processing for changing the saturation or hue.

FIG. 53 shows a frame 28 corresponding to the passage of time.
FIG. 6 is a diagram illustrating an example of a change of one hue.

For example, the display program 54F linearly changes the hue of the frame 281 corresponding to 0 degree of the hue circle in three seconds in one second.
Frame 2 that changes to 60 degrees and reaches 360 degrees on the hue circle
The hue of 81 is returned to 0 degrees, and this change is repeated.

By doing so, the display program 5
4F displays a thumbnail 201 having various brightness, color, or hue from a screen on which a thumbnail 201 is displayed.
The selected thumbnail 201 can be surely recognized. The cycle of the change in the brightness, saturation, or hue of the frame 281 is not limited to one second, but is, for example, 0.1 second to 10 seconds.
A period that can be recognized by a user on the order of seconds may be used.

FIG. 54 shows the selected thumbnail 20.
FIG. 5 is a diagram for explaining display of data attributes and the like corresponding to No. 1; When the thumbnail 201 is selected, the display program 54F displays a frame 281. When a predetermined time elapses without operating the touch pad 6 or the like, the display program 54F displays the frame 281.
The attributes such as the file name of the file in which the data corresponding to No. 1 is stored, the title of the data, the size of the data, and the reproduction time are displayed on the additional attribute display 291.

When the thumbnail 201 is not selected, the display program 54F displays the thumbnail 201
Is deleted, and the frame 281 and the additional attribute display 291 corresponding to are deleted.

For example, as shown in FIG. 55, when one second elapses after the thumbnail 201 is selected, the display program 54F displays attributes such as a file name, an icon indicating a still image or a moving image, data size, and date. Is displayed on the additional attribute display 291. In the example shown in FIG. 55, the additional attribute display 291 indicates that the other thumbnails 20 that have not been selected are displayed.
In order to allow the user to confirm 1, the frame and the background thereof are translucently displayed.

Next, a full-screen display mode for displaying the entire LCD 7 will be described. Display program 54F
Displays a thumbnail 201 or the like in a predetermined range of the display area of the screen of the LCD 7 when activated, as shown in FIG.

When a predetermined icon or a predetermined key of the keyboard 5 is operated, the display program 54F displays FIG.
As shown in the figure, the thumbnail 201 and the like are displayed on the entire display area of the screen of the LCD 7. When the display program 54F displays an image on the entire display area of the screen of the LCD 7, the personal computer 1 operates the jog dial 4, the touch pad 6, the keyboard 5, and the like except for the operation of a specific key combination. Then, an input is accepted as an operation on the display program 54F.

When the thumbnail 201 or the like is displayed in a predetermined range of the display area of the screen of the LCD 7, when the icon 301 shown in FIG. 58 is operated, the display program 54F
Indicates that a thumbnail 20 is displayed on the entire display area of the screen of the LCD 7.
1 or the like is displayed. When the thumbnail 301 or the like is displayed on the entire display area of the screen of the LCD 7, when the icon 301 shown in FIG. 58 is operated, the display program 54F is displayed.
Displays the thumbnail 201 and the like in a predetermined range of the display area of the screen of the LCD 7.

When the thumbnail 201 or the like is displayed in the entire display area of the screen of the LCD 7, clicking the icon 311 shown in FIG. 59 causes the display program 54F to
The thumbnail 2 is displayed in a predetermined range of the display area of the screen of the LCD 7.
01 and the like, and activates another application program corresponding to the icon 311.

As described above, the display program 54F can display the thumbnail 201 and the like on the entire display area of the screen of the LCD 7 when the operation of the icon 301 or the predetermined key of the keyboard 5 is operated. LCD7
When the thumbnail 201 or the like is displayed in the entire display area of the screen of, the display program 54F can directly start another application program in response to the operation of the icon 311. By displaying the thumbnail 201 or the like on the entire screen of the LCD 7, it is possible to prevent the user from erroneous operation such as operating another application program.

When another application program corresponding to the icon 311 is started, the user often wants to link the display program 54F with the other application program.
4F automatically displays the thumbnail 201 and the like in a predetermined range of the display area of the screen of the LCD 7. The user can operate the display program 54F and other application programs more efficiently.

Next, the processing of the display program 54F and the reading program 54G executed by the CPU 51 will be described.

FIG. 60 is a flowchart for explaining the content reading process of the display program 54F and the reading program 54G. In step S11, the reading program 54G reads the number of contents stored in the memory stick 116 via the memory stick interface 114.
The reading program 54G is the memory stick 11
Display program 5 to display the number of contents stored in
Supply to 4F.

In step S12, the reading program 54G reads the memory stick interface 1
The contents stored in the memory stick 116 are sequentially read via the memory 14, and the read contents are supplied to the display program 54F. The process of reading the content from the memory stick 116 by the reading program 54G is executed in parallel with the following process.

In step S13, the processing manager 151 of the display program 54F obtains the number of contents read by the reading program 54G based on the data supplied from the reading program 54G. In step S14, the processing manager 151 of the display program 54F specifies the first content read by the reading program 54G.

In step S15, the processing manager 151 of the display program 54F calculates a position at which the thumbnail 201 corresponding to the content is displayed. In step S16, the content processing routine 152 of the display program 54F generates a thumbnail 201 corresponding to the read content. In step S17, the content processing routine 152 of the display program 54F displays the thumbnail 201 at the position calculated by the processing manager 151. Content processing routine 1
52 indicates that the thumbnail 201 is not displayed when the position where the thumbnail 201 is displayed is outside the display area of the LCD 7.

[0239] In step S18, the display program 54F determines whether or not the thumbnails 201 corresponding to all the read contents have been generated, and determines that the thumbnails 201 corresponding to all the contents have not been generated. If it has, the process proceeds to step S19, and the processing manager 151 of the display program 54F specifies the next content read by the reading program 54G.

[0240] In step S20, the processing manager 151 of the display program 54F determines the number of contents for which the reading program 54G has finished reading, based on the data supplied from the reading program 54G.
Returning to step S15, the process of generating the thumbnail 201 is repeated.

If it is determined in step S18 that the thumbnails 201 corresponding to all the contents that have been read have been generated, the process proceeds to step S21, where the display program 54F reads all the contents stored in the memory stick 116. If it is determined that all the contents stored in the memory stick 116 have not been read, the process returns to step S12, and the processing is repeated from reading the contents.

If it is determined in step S21 that all the contents stored in the memory stick 116 have been read, the thumbnail 2
01 has been generated and the predetermined thumbnail 201 has been generated, and the process ends.

As described above, the display program 54F and the reading program 54G correspond to the memory stick 11
6, the content is read out sequentially, and a thumbnail 201 is generated in correspondence with the read out content.
D7 can be displayed.

Next, the process of displaying audio data by the display program 54F will be described with reference to the flowchart in FIG. In step S31, the display program 54F divides the thumbnail 201 having a predetermined size into a predetermined number of areas corresponding to the size of the audio data. The display program 54F increases the number of divisions of the thumbnail 201 when the audio data is large, and decreases the number of divisions of the thumbnail 201 when the audio data is small.

In step S32, the display program 54F extracts, from the audio data, data having a predetermined length corresponding to the number of divisions (the number of areas) of the thumbnail 201. In step S33, the display program 54F
Converts the extracted data into RGB data (the same number of RGB data as the number of areas) by the process described with reference to FIG. In step S34, the display program 54F sets each data of RGB in each of the areas of the thumbnail 201 generated by the division.

[0246] In step S35, the display program 54F performs a blurring process (blur process) on the thumbnail 201. In step S36, the display program 54F overwrites a predetermined position of the thumbnail 201 with a text indicating an attribute corresponding to the audio data, and the process ends.

As described above, the display program 54F can generate the thumbnail 201 of the audio data corresponding to the size of the audio data. Display program 54
F generates a thumbnail 201 corresponding to data such as text by the same processing.

Next, the process of displaying a line view by the display program 54F will be described with reference to the flowchart in FIG. In step S51, the display program 54F determines the number of axes 221. For example,
The display program 54F sets the number of axes 221 to 1 when displaying only the thumbnail 201, and sets the number of axes 221 to 2 when displaying the thumbnail 201 and the text 211.
And

In step S52, the display program 54F calculates the axis 221 based on the equation (1) or (2).
Determine the orientation of In step S53, the display program 54F determines the display position of the thumbnail 201 based on the axis 221.

In step S54, the display program 54F determines whether or not to display the text 211 corresponding to the content.
If it is determined that 11 is to be displayed, the process proceeds to step S55, and the arrangement of the text 211 is determined based on the axis 221. In step S56, the display program 54F
Displays the text 211 at the position determined in the process of step S55, and proceeds to step S57.

When it is determined in step S54 that the text 211 corresponding to the content is not to be displayed,
Since the process of displaying the text 211 is not required, the processes of steps S55 and S56 are skipped,
The procedure proceeds to step S57.

[0252] In step S57, the display program 54F sets the position determined by the processing in step S53 to
The thumbnail 201 is displayed, the process returns to step S52, and the display process is repeated.

As described above, the display program 54F
The thumbnail 201 and the text 211 are displayed based on the open axis 221 such as a straight line or a curve.

Next, the process of displaying the loop view by the display program 54F will be described with reference to the flowchart in FIG. In step S71, the display program 54F determines the number of axes 241. For example,
The display program 54F sets the number of axes 241 to 1 when displaying only the thumbnail 201, and sets the number of axes 241 to 2 when displaying the thumbnail 201 and the text 211.
And

At step S72, the display program 54F determines the shape of the axis 241. In step S73, the display program 54F determines the display position of the thumbnail 201 based on the axis 241 by, for example, Expression (6).

[0256] In step S74, the display program 54F determines whether or not to display the text 211 corresponding to the content.
If it is determined that 11 is to be displayed, the process proceeds to step S75, and the arrangement of the text 211 is determined based on the axis 241. In step S76, the display program 54F
Displays the text 211 at the position determined by the processing in step S75, and proceeds to step S77.

If it is determined in step S74 that the text 211 corresponding to the content is not to be displayed,
Since the process of displaying the text 211 is not required, the processes of steps S75 and S76 are skipped,
The procedure proceeds to step S77.

[0258] In step S77, the display program 54F moves the position determined by the processing in step S73 to the position determined by the processing in step S73.
The thumbnail 201 is displayed, the process returns to step S73, and the display process is repeated.

As described above, the display program 54F
The thumbnail 201 and the text 211 are displayed based on a closed axis 241 such as a circle or an ellipse.

Next, the display processing of the spiral view by the display program 54F will be described with reference to the flowchart in FIG. In step S91, the display program 54F determines the number of axes 261. For example, when displaying only the thumbnail 201, the display program 54F sets the number of axes 261 to 1, and
When displaying 1 and the text 211, the number of axes 261 is set to 2.

[0261] In step S92, the display program 54F determines whether or not the jog dial 4, the keyboard 5, or the touch pad 6 has been operated to input a selection of the thumbnail 201, and the selection of the thumbnail 201 has been input. If it is determined that there is not, step S9
Proceed to 3 to set a spiral with a large radius r on the shaft 261 and proceed to step S95.

At step S92, the thumbnail 20
If it is determined that selection 1 has been input, the process proceeds to step S94, and the display program 54F sets a spiral with a smaller radius r on the axis 261 in accordance with the frequency of selection input per unit time. The process proceeds to step S95.

In step S95, the display program 54F calculates the thumbnail 201 based on the axis 261 by using, for example, Expressions (11), (12) and (13).
Determine the display position of.

[0264] In step S96, the display program 54F determines whether or not to display the text 211 corresponding to the content.
If it is determined that 11 is to be displayed, the process proceeds to step S97, and the arrangement of the text 211 is determined based on the axis 261. In step S98, the display program 54F
Displays the text 211 at the position determined in the process of step S97, and proceeds to step S99.

If it is determined in step S96 that the text 211 corresponding to the content is not to be displayed,
Since the process of displaying the text 211 is not necessary, the processes of steps S97 and S98 are skipped,
The procedure proceeds to step S99.

[0266] In step S99, the display program 54F moves the position determined by the processing in step S95 to
The thumbnail 201 is displayed, the process returns to step S92, and the display process is repeated.

As described above, the display program 54F displays the thumbnail 201 and the text 211 based on the spiral axis 261. If it is determined that the selection of the thumbnail 201 has been input, the display program 54F determines the thumbnail 201 based on the spiral axis 261 having a small radius r.
And the text 211 are displayed.

Next, the process of moving the icon 202 by the display program 54F will be described with reference to the flowchart in FIG. In step S111, the processing manager 151 of the display program 54F selects one of the icons 202 based on the input from the touch pad 6.
It is determined whether or not is clicked, and any icon 2
If it is determined that 02 has not been clicked, the process returns to step S111, and the determination process is repeated until one of the icons 202 is clicked.

If it is determined in step S111 that one of the icons 202 has been clicked, the flow advances to step S112, and the processing manager 151 of the display program 54F calculates the final display position of each icon 202. I do.

[0270] In step S113, the processing manager 151 of the display program 54F determines in step S112
The display positions of the respective icons 202 are calculated based on the final display positions of the respective icons 202 and the elapsed time from the click, which are calculated in the processing of (1).
In step S114, the icon processing routine 152 of the display program 54F displays the icon 202 at the display position calculated in the processing of step S113.

The icon 202 in step S114
Is executed at a cycle set by the processing manager 151. By appropriately selecting the processing cycle of the display of the icon 202, the icon 202 is displayed as if it is moving.

In step S115, the processing manager 151 of the display program 54F determines whether each icon 202 has been displayed at the final display position, and each icon 202 has been displayed at the final display position. If it is determined that there is no icon, the process returns to step S113, and the process of displaying the icon is repeated.

If it is determined in step S115 that each icon 202 has been displayed at the final display position, the process returns to step S111, and the processing is repeated from the processing of determining whether or not icon 202 has been clicked.

As described above, the display program 54F can display the icon 202 so as to move at a predetermined speed when the icon 202 is clicked.

Next, the process of displaying an afterimage by the display program 54F will be described with reference to the flowchart in FIG. In step S131, the display program 54F draws the already displayed image with a reduced brightness (for example, 80%).

In step S132, the display program 54F draws a new image by overwriting the image drawn in step S131, returns to step S131, and repeats the drawing process.

As described above, the display program 54F draws the image so that the brightness of the already drawn image gradually decreases.
Since the new image is overwritten, the afterimage can be easily displayed.

Next, the state transition processing by the display program 54F will be described with reference to the flowchart in FIG. In step S151, the display program 54F displays the current thumbnail 201 or icon 20.
The original state of transition, such as the display position of 2, is recorded. In step S152, the display program 54F determines the state of the transition destination such as the display position of the destination of the thumbnail 201 or the icon 202.

[0279] In step S153, the display program 54F obtains the importance of the transition. For example, the importance of the transition is predetermined for each transition, and the display program 54F
Is stored in In step S154, the display program 54F determines a transition function based on the importance of the transition. For example, the display program 54F selects a transition function that makes a state transition slowly when the importance of the transition is large, and selects a transition function that makes a state transition quickly when the importance of the transition is small.

[0280] In step S155, the display program 54F calculates the next state based on the transition function corresponding to the elapsed time. In step S156, the display program 54F shifts to the state calculated in the processing in step S155. For example, the display program 54F calculates the positions of the thumbnail 201 and the icon 202 corresponding to the elapsed time in Step S155, and adds the thumbnail 2 to the calculated position in Step S156.
01 and the icon 202 are displayed.

In step S157, the display program 54F determines whether or not to change the state of the transition destination based on the signals from the jog dial 4, the touch pad 6, or the keyboard 5, and determines whether or not to change the state of the transition destination. If it is determined that is not changed, the process proceeds to step S158.

If it is determined in step S157 that the state of the transition destination is to be changed, the flow advances to step S159 to set the current state to the original state of the transition. In step S160, the display program 54F determines the state of the transition destination, such as the display position of the destination of the thumbnail 201 or the icon 202.

[0283] In step S161, the display program 54F obtains the importance of a new transition. Step S
At 162, the display program 54F determines a transition function based on the importance of the new transition.

[0284] In step S158, the display program 54F compares the current state with the state of the transition destination, determines whether or not the state of the transition destination has been reached, and has reached the state of the transition destination. If it is determined that there is no state, the process returns to step S155, and the processing is repeated from the processing of calculating the next state.

If it is determined in step S158 that the state of the transition destination has been reached, the processing ends.

As described above, the display program 54F
Based on the transition function, the display state and the like are changed, and when a request is made during the transition, the state is changed to the requested state. Further, since the display program 54F selects the transition function based on the importance of the transition, the transition is performed relatively slowly so that the user can surely recognize the state transition in the transition having a high importance. In the case of a transition having a low degree of importance, the state is quickly shifted.

Next, the process of enlarged display by the display program 54F will be described with reference to the flowchart in FIG. In step S181, the display program 54F determines whether or not the thumbnail 201 has been clicked on the basis of the signal from the touch pad 6, and if it is determined that the thumbnail 201 has not been clicked, the process returns to step S181. Is repeated.

If it is determined in step S181 that the thumbnail 201 has been clicked, the flow advances to step S182, and the display program 54F determines whether or not the clicked thumbnail 201 is located at the center of the window.

If it is determined in step S182 that the clicked thumbnail 201 is not located at the center of the window, the process proceeds to step S183, where the display program 54F displays the clicked thumbnail 201 such that it is located at the center of the window. Is changed, the process returns to step S181, and the process is repeated.

If it is determined in step S182 that the clicked thumbnail 201 is located at the center of the window, the process proceeds to step S184, where the display program 54F enlarges and displays the clicked thumbnail 201 (when the thumbnail 201 is a still image). If it corresponds to data, it is displayed in its original size, if it corresponds to moving image data, a moving image is generated, and if it corresponds to audio data, audio is reproduced), the process returns to step S181, and the process is performed. repeat.

As described above, when the thumbnail 201 is clicked, the display program 54F displays the clicked thumbnail 201 at the center or enlarges the displayed thumbnail 201.
01 can be quickly known by simple operation.

Next, the process of displaying the frame 281 by the content processing routine 15 of the display program 54F will be described with reference to the flowchart of FIG. In step S201, the content processing routine 152
Determines whether the thumbnail 201 displayed by the user is selected, and determines whether the thumbnail 201 displayed by the user is selected.
If it is determined that 01 has not been selected, step S
Returning to 201, the determination process is repeated until the thumbnail 201 displayed by the user is selected.

If it is determined in step S201 that the thumbnail 201 displayed by the user is selected, the process proceeds to step S202, and the content processing routine 152 starts counting the elapsed time. The process of counting up the elapsed time is continued in the execution of the following process.

[0294] In step S203, the content processing routine 152 determines a brightness change function, for example, as shown in Fig. 52. In step S204, the content processing routine 152 determines the frame 2 based on the elapsed time.
The lightness of 81 is calculated. In step S205, the content processing routine 152 displays the brightness frame 281 calculated in the processing in step S204.

In step S206, the content processing routine 152 determines that the thumbnail 2
It is determined whether or not 01 has been selected, and if it is determined that the thumbnail 201 displayed by the user has been selected, the process proceeds to step S204, and the process of displaying the frame 281 is repeated.

If it is determined in step S206 that the thumbnail 201 displayed by the user is not selected, the process proceeds to step S207, where the content processing routine 152 deletes the frame 281 and returns to step S201 to return to the frame 281. Is repeated.

As described above, the display program 54F can display the frame 281 in which the brightness is periodically changed on the selected thumbnail 201. The display program 54F performs a similar process to the frame 281 in which the saturation or hue is periodically changed for the selected thumbnail 201.
Can be displayed.

Next, the process of displaying the additional attribute display 291 by the content processing routine 15 of the display program 54F will be described with reference to the flowchart of FIG. In step S221, the display program 54F
Determines whether or not a display change has been input based on signals supplied from the jog dial 4, the touch pad 6 or the keyboard 5, respectively. If it is determined that the display change has not been input, Proceeding to S222, the content processing routine 152 determines whether or not the thumbnail 201 displayed by the user is selected.

If it is determined in step S222 that the thumbnail 201 displayed by the user is selected, the process proceeds to step S223, and the content processing routine 152 determines that the thumbnail 201 has been selected for a predetermined time (for example, (1 second) has elapsed.

[0300] If it is determined in step S223 that the predetermined time has elapsed, the flow advances to step S224.
The content processing routine 152 displays an additional attribute display 291 including a text corresponding to the thumbnail 201 and having a translucent frame and background, returns to step S221, and repeats the processing.

[0301] If it is determined in step S221 that a change in display has been input, processing such as moving the thumbnail 201 has been executed, so the flow advances to step S225, and the content processing routine 152 determines The corresponding additional attribute display 291 is deleted, the process returns to step S221, and the process is repeated.

[0302] If it is determined in step S222 that the thumbnail 201 displayed by the user is not selected, the display of the additional attribute 291 is not necessary, so the process proceeds to step S225, and the content processing routine 152 proceeds to step S225. Additional attribute display 2 corresponding to 201
91 is deleted, the process returns to step S221, and the process is repeated.

If it is determined in step S223 that the predetermined time has not elapsed, the flow advances to step S225, where the content processing routine 152
The additional attribute display 291 corresponding to 01 is deleted, the process returns to step S221, and the process is repeated.

As described above, the display program 54F displays the additional attribute display 291 corresponding to the selected thumbnail 201 after a predetermined time has elapsed after the thumbnail 201 has been selected. And the operation of the user can be prevented.

Since the frame and background of the additional attribute display 291 displayed by the display program 54F are translucent, the user
It is possible to confirm the thumbnail 201 and the like arranged below the additional attribute display 291 (the back side of the screen).

Next, LC by the display program 54F
FIG. 71 shows a process of selecting the first display mode in which the thumbnail 201 and the like are displayed in a predetermined area on the display surface of D7 or the second display mode in which the thumbnail 201 and the like are displayed on the entire display surface of the LCD 7. This will be described with reference to a flowchart. In step S251, the display program 54F executes the first display mode (displays a thumbnail 2 in a predetermined area on the display surface of the LCD 7) to display a frame of the predetermined area.
01 etc.).

[0307] In step S252, the display program 54F determines whether or not another application program has been started. If it is determined that another application program has been started, the display program 54F sets the first display mode. Is returned, and the process returns to step S252 to repeat the determination process.

If it is determined in step S252 that another application program has not been activated, the flow advances to step S253 to display the display program 54F.
Determines whether or not a change in the display mode has been input based on signals supplied from the jog dial 4, the touch pad 6, or the keyboard 5, respectively.

If it is determined in step S253 that the change of the display mode has not been input, the display mode does not need to be changed, and the process returns to step S252.
The determination process is repeated.

If it is determined in step S253 that a change of the display mode has been input, step S254 is performed.
Then, the display program 54F sets the second display mode for displaying the entire display screen of the LCD 7.

[0311] In step S255, the display program 54F determines whether or not another application program has been activated. If it is determined that another application program has not been activated, the display program 54F proceeds to step S25.
The process proceeds to step S6, where it is determined whether or not a change in the display mode has been input based on the signals supplied from the jog dial 4, the touch pad 6, or the keyboard 5, respectively.

If it is determined in step S256 that the change of the display mode has not been input, the process returns to step S255 because there is no need to change the display mode.
The determination process is repeated.

If it is determined in step S256 that a change of the display mode has been input, step S251 is performed.
The display program 54F sets the first display mode and repeats the processing.

If it is determined in step S255 that another application program has been started, the display mode is changed to the first display mode. Therefore, the flow returns to step S251, where the display program 54F sets the first display mode and executes processing. repeat.

As described above, the display program 54F switches between the first display mode and the second display mode in response to the input, and switches to the first display mode when another application program is started. be able to.
