As shown in FIG. 3, the handwriting tablet 110 has a resistive film 30 for detecting input coordinates in the X direction.
1 and a resistive film 302 for detecting input coordinates in the Y direction
Are provided. Detection terminals are formed at the left and right ends of the resistance film 301, respectively, and the detection terminals are respectively connected to external connection terminals 305c (X1) and 305d (X2). Detection terminals are formed at upper and lower ends of the resistance film 302, respectively, and the detection terminals are respectively connected to external connection terminals 305a (Y1) and 305b (Y2). Each of the above-described external connection terminals 305a to 305d
Are connected to the tablet control unit 109.

Next, a coordinate detection process for detecting the coordinates of the input position on the touch panel 106 will be described with reference to FIG. FIG. 4 is a flowchart showing a procedure of a coordinate detection process in the electronic device of FIG.

This coordinate detection process is a process executed by the CPU 101 based on an interrupt signal generated each time a timer built in the CPU 101 measures a predetermined time. Executed according to the program. When the coordinate detection process is started by the interrupt signal, as shown in FIG. 4, first, in step S401, a pen input detection set is performed. In this pen input detection set, settings for determining pen input are made to the tablet control unit 109. The tablet control unit 109 applies 5 V to the external terminal Y1 (external connection terminal 305a), and outputs the external terminal Y2 (3
05b) set to open (do not connect to anything)
The external terminal X1 (305c) is connected to the A / D converter, and the external terminal X2 (305d) is set to open. Switching between these terminals is performed by a circuit provided inside the tablet control unit 109 and configured by transistors and the like.

Next, in step S402, the voltage of the external terminal X1 (305c) is A / D converted, and the presence or absence of pen input is determined based on the digital signal obtained by the A / D conversion. Here, as shown in FIG.
2, when the resistance film 301 of the handwriting tablet 10 is pressed, the point Xp (30) on each of the resistance films 301 and 302 is pressed.
3), Yp (304) contacts. Currently external terminal Y1
Assuming that 5 V is applied to (305a), the point Xp
(303), a potential of 5 V is detected through Yp (304) through the external terminal X1 (305c). On the other hand, when there is no pen input, the external terminal X1 (305
c) is pulled down (connected to ground potential through a resistor) in the tablet control unit 109,
A potential of 0 V is detected. Therefore, the external terminal (305
If the result of the A / D conversion of c) is 0 V, it is determined that there is no pen input, and if the result is 5 V, it is determined that there is pen input. Note that in an actual circuit, noise and a loss voltage due to circuit and wiring resistance occur, so that the range of the voltage to be determined is provided. For example, if the result of the A / D conversion is 4 V, it is determined that there is a pen input.

If it is determined in step S402 that there is a pen input, the flow advances to step S403 to perform an X coordinate detection set for detecting the X coordinate by the tablet control unit 109. In this X coordinate detection set, the external terminal Y1 (external connection terminal 305a) is connected to the A / D converter, the external terminal Y2 (305b) is set to open (no connection is made), and the external terminal X1 (305c) is set. Is connected to the ground, and 5 V is applied to the external terminal X2 (305d). In a succeeding step S404, the external terminal Y1
The value of the X coordinate is detected by A / D converting the voltage of (305a). Here, since the external terminal X1 (305c) is at 0V and the external terminal X2 (305d) is at 5V, the external terminal Y
1 shows the voltage at the pressed point Xp (303) of the resistive film 301, and this voltage has a value proportional to the distance from the left end. That is, a higher voltage is detected as the pressed point Xp (303) moves to the right. Further, conversion to coordinates corresponding to the display unit 113 is performed based on the detected voltage. This coordinate conversion is performed based on the following equation (1).

X = Vx / (5 / Xdot) (1) where X is the display unit 1 corresponding to the pressed point Xp (303).
13, the X coordinate of the position on 13, Vx is the detected voltage, and Xdot indicates the total number of dots in the X direction of the display unit 113. Further, “5” in the equation represents a voltage applied to X2 (305d). However, when a voltage loss occurs due to a circuit, wiring resistance, or the like, it is necessary to substitute a value in consideration of the voltage loss in place of “5”.

Next, the process proceeds to step S405, where the Y coordinate detection set is performed in the same manner as the X coordinate detection set. This Y
In the coordinate detection set, 5V is applied to the external terminal Y1 (305a).
Is applied, the external terminal Y2 (305b) is connected to the ground, the external terminal X1 (305c) is connected to the A / D converter, and the external terminal X2 (305d) is opened. In the following step S406, similarly to the detection of the X coordinate, the value of the Y coordinate is detected by A / D converting the voltage of the external terminal Y1 (305a). Here, Y is depressed point Yp (30
If Y is the value of the Y coordinate of the position on the display unit 113 corresponding to 4), Vy is the detected voltage, and Ydot is the total number of dots in the Y direction of the liquid crystal display 108, Y1 (30
Since the voltage applied to 5a) is 5 V, the value of the Y coordinate is calculated based on the following equation (2).

Y = Vy / (5 / Ydot) (2) However, when a voltage loss occurs due to a circuit, wiring resistance, or the like, a value considering this voltage loss is substituted for “5”. There is a need.

Next, the flow advances to step S407 to determine the presence or absence of pen input. This determination is made in order to eliminate the influence of chattering, noise, and the like at the time of input. Here, if there is a pen input, the process proceeds to step S408, where RA
With reference to the continuous flag Xa stored in the work area 103b of M103, it is determined whether or not this pen input is a continuous input. Here, when the continuous flag Xa is set, it is determined that the pen input is a continuous input, and the process proceeds to step S409.
The X and Y coordinate data calculated in S406 is temporarily stored in the coordinate storage area 103e of the RAM 103 as continuous input data. When storing the coordinates, information indicating that the stored coordinate data is continuous input data is stored in association with the coordinate data. Then, the process exits. Coordinate storage area 10
Each application determines whether or not the data stored in 3e is coordinate data in a necessary range, and the application acquires necessary data according to this determination and executes a corresponding operation.

On the other hand, if it is determined in step S408 that the continuation flag Xa is not set, it is determined that the pen input is not a continuous input, and the flow advances to step S410 to calculate in steps S404 and S406. The X and Y coordinate data are temporarily stored in the coordinate storage area 103e of the RAM 103. When storing these coordinates,
Information indicating that the stored coordinate data is not continuous input data is stored in association with the information. In a succeeding step S411, the continuous flag Xa is set, and the process exits.

If it is determined in step S402 that there is no pen input, the flow advances to step S412 to determine whether or not the continuation flag Xa has been set. If the continuation flag Xa has been set, the flow advances to step S413. The data that the input pen 202 has been released from the handwriting tablet 110 is stored in the coordinate storage area 103e, and the process proceeds to step S414. If the continuation flag Xa is not set, the process skips step S413 and proceeds to step S414. In step S414, the continuation flag Xa is reset, and the process exits.

If it is determined in step S407 that there is no pen input, it is determined that the pen input determined in step S402 is an invalid input due to the influence of chattering, noise, or the like at the time of input, and S402
As in the case where it is determined that there is no pen input, the process proceeds to step S412.

Next, a menu selection process in the electronic device will be described with reference to FIG. FIG. 5 is a flowchart showing a procedure of menu selection processing in the electronic device of FIG.

When the power is turned on, as shown in FIG.

To display the menu. In this menu display, the display unit 113 displays a menu screen for selecting each individual process such as shooting and image reproduction according to each application program stored in the ROM 102 in advance.

Next, the process proceeds to step S503, and it is determined whether or not there is a pen input for selecting individual processing. In this determination, the presence or absence of a pen input is determined with reference to the coordinate data stored in the coordinate storage area 103e of the RAM 103.
If there is no pen input, the process waits until there is a pen input, and if there is a pen input, the process proceeds to step S504. Step S504
Then, referring to the coordinate data stored in the coordinate storage area 103e, it is determined which of the individual processes the pen input is an input to select. If the pen input is an input for selecting the shooting menu, step S
In step S505, the application program related to the photographing function is executed. After the execution of the application program is completed, the process returns to step S502 again, and the display unit 1
13 displays a menu screen. If the pen input is an input for selecting the image reproduction menu, step S50
The program proceeds to step S6, where the application for image reproduction is executed. After the execution of the application program, the process returns to step S502 again to display the menu screen on the display unit 113. If the pen input is an input for selecting another menu (phonebook, schedule, clock), the process proceeds to step S507, where an application program corresponding to the selected menu is executed, and after the execution of this program is completed, the process returns to step S502 again. Return, display unit 113
To display the menu screen.

Next, the procedure of the photographing operation executed in step S505 will be described with reference to FIGS. FIG. 6 is a flowchart showing the procedure of the photographing operation in step S505 in FIG. 5, and FIGS. 7 and 8 are flowcharts showing the procedure of an interruption process by a key input operation during the photographing operation.

When the photographing operation is selected, first, as shown in FIG.
The CCD module including the CD control unit 107 is brought into an operable state (enable).

Then, the flow advances to step S602 to determine whether or not an interrupt event has occurred due to a key input operation. When the interrupt event has occurred, the process proceeds to step S70 shown in FIG.
1 or step S714 shown in FIG. 8, and if no interrupt event has occurred, the process proceeds to step S603. Here, the key input operation means the shutter SW11
4 pressing operation and various setting key operations. The pressing operation of the shutter SW 114 includes a half-press position,
An operation corresponding to each of the shutter 0N positions is included.

In step S 603, a process for taking in an analog electric signal of an optical image obtained by photoelectric conversion by the CCD 106 is performed. Here, the signal output from the CCD 106 is 640 × 48 in order to increase the processing speed.
It is not the total pixel of 0 dot, but the thinned 320
It is a non-interlaced analog signal of × 240 dots.

In the following step S604, the CCD 106
Analog signal from the CCD controller 107
After performing noise removal processing and gain processing,
A / D conversion into a 0-bit digital signal and image processing unit 10
8 is output.

Next, the process proceeds to step S605, in which the image processing unit 108 performs processing such as correction for auto white balance, AE, and flash photography, or YUV.
Processing such as signal conversion into a (4: 2: 2) format is performed. The YUV-converted signal is written into the VRAM 103c by the CPU 101, and the VRAM 103c
The YUV signal written to is constantly LC
It is output to the D control unit 111.

Next, the process proceeds to step S606, where the LCD
The YUV signal read from the VRAM 103c is converted into an RGB signal by the control unit 111, and in step S607, the RGB signal is output to the display drive unit 112. In step S608, the LCD control unit 111 is output by the display drive unit 112. The display unit 113 is driven on the basis of the RGB signals from the CPU and the captured image (subject image) is displayed on the display unit 113.

As described above, steps S602 to S6
By repeating the processing up to 08 continuously in a cycle of 1/30 second, the day view finder processing for displaying the captured image on the display unit 113 is executed. If a key input operation by the photographer is detected during the viewfinder processing, an interrupt event occurs, and this interrupt event is detected in step S602. When this interrupt event is detected, the process proceeds to step S701 shown in FIG. 7 or step S714 shown in FIG. Here, at the stage when this interrupt event occurs, either the normal mode or the half-press mode is set internally. The normal mode is a mode in which the processing shown in FIG. 6 is executed. When an interrupt event occurs due to a key input operation in the normal mode state, the flow proceeds to step S701 shown in FIG. The half-press mode is a state in which the shutter SW 114 is pressed to the half-press position and various camera settings are locked.
When an interrupt event occurs due to a key input operation in this half-press mode,
The transition to step S714 shown in FIG. 8 is performed.

When an interrupt event occurs due to a key input operation in the normal mode, step S701 shown in FIG.
The key status is read to determine the operated key, and in a succeeding step S702, it is determined whether or not the shutter SW 114 has been pressed to the shutter ON position. If the shutter SW 114 has been pressed down to the shutter ON position, the flow advances to step S703 to set various camera settings controlled in the image processing unit 108, such as auto white balance, AE, and flash correction in flash shooting, to the current settings. Then, the process proceeds to step S716 shown in FIG.

In step S716, the VGA standard (64
A capture signal of a full image (0 × 480 dots) is captured, a predetermined process is performed by the image processing unit 108, and the YUV signal obtained by this process is written to the image development area 103 a of the RAM 103. Here, in the above-described viewfinder processing, a thinned image signal is fetched in order to increase the processing speed.
Since a full image of the standard (640 × 480 dots) is required, a capture signal of the full image is captured.

Next, the process proceeds to step S717, where the JPE
A compression process conforming to the G standard is performed on the captured image signal, and in the subsequent step S718, a selection menu for selecting a folder as a storage destination of the captured image is displayed on the display unit 1.
13 and waits for a folder selection in step S719.

When the folder for storing the captured image is selected, the flow advances to step S720 to store the compressed image data in the data storage unit 104 (flash memory) as an image file belonging to the selected folder. In the following step S721, the photographed image is displayed on the display unit 113 so that the photographed image can be confirmed, and the time is displayed. After exiting this processing, the process moves to step S602 shown in FIG.
Resume viewfinder processing.

If it is determined in step S702 that the shutter SW 114 has not been pressed down to the shutter ON position, the flow advances to step S704 to determine whether or not the shutter SW 114 is at the half-pressed position. If it is at the push position, the process proceeds to step S705, where the internal state is set to the half-press mode state. At step S706, as in step S703, auto white balance, AE, strobe correction for strobe shooting, etc. The various camera settings controlled in the image processing unit 108 are held at the current setting values, and the processing exits from this processing and proceeds to step S602 shown in FIG. 6, where the viewfinder processing is restarted.

If it is determined in step S704 that the shutter SW 114 is not at the half-pressed position, it is determined that the operated key is not the shutter SW 114, and the flow advances to step S707 to determine whether the operated key is a setting change key. If it is determined whether the operated key is the setting change key, the process proceeds to step S708. In step S708, camera mode setting is performed.
Here, various camera settings controlled in the image processing unit 108, such as auto white balance, AE, and strobe correction in the case of strobe shooting, are changed and set according to the input conditions. Then, the process goes through step S602 shown in FIG. 6 after exiting this process, and the viewfinder process is restarted.

If it is determined in step S707 that the operated key is not the setting change key, the flow advances to step S709 to determine whether the operated key is the shooting end key. If the operated key is the shooting end key, the process advances to step S710 to end the display driving, and in the following step S711, the operation of the CCD module ends, and the main shooting operation ends. If the operated key is not the shooting end key, it is determined that a valid key or switch operation has not been detected, the process exits the process, the process proceeds to step S602 shown in FIG. 6, and the viewfinder process is restarted.

When an interrupt event occurs due to a key input operation in the half-press mode, step S71 shown in FIG.
In step S715, the process proceeds to step S715, where it is determined whether or not the shutter SW 114 has been pressed to the shutter ON position. If the shutter SW 114 is pressed down to the shutter ON position, step S716 is performed with various camera settings, such as auto white balance, AE, and strobe correction for strobe shooting, already set in a half-pressed state.
Proceed to. The series of processing from step S716 to step S721 is as described above, and a description thereof will be omitted.

If the shutter switch 114 has not been pressed to the shutter ON position, the flow advances to step S722 to determine whether or not half-press release has been detected.
Proceeding to 723, the half-press mode is canceled to set the normal mode state. Then, the process goes through step S602 shown in FIG. 6 after exiting this process, and the viewfinder process is restarted. If half-press release is not detected, it is determined that a valid key input operation has not been detected, and the process exits the process. The process shifts to step S602 shown in FIG. 6 to restart the viewfinder process.

Next, the image reproducing process in step S506 in FIG. 5 will be described with reference to FIGS. 9 to 11 are flowcharts showing the procedure of the image reproduction process in step S506 in FIG. 5, FIG. 12 is a diagram showing a screen display example in step S802 in FIG. 9, and FIG.
FIG. 14 is a diagram showing an example of the screen display of step S803 of FIG. 13, FIG. 14 is a diagram showing an example of the display change of the time axis displayed on the screen of FIG. 13, and FIG. 15 is a diagram showing an example of the screen display of step S823 of FIG. .

In the image reproducing process, as shown in FIG. 9, first, the display mode selected in step S801 is determined. Here, the present apparatus is provided with two reproduction modes in advance, and determines the display mode in which mode the stored image is to be displayed. One of the playback modes is a folder display mode, and the other is a time series display mode. The flag stored in the flag area 103f of the RAM 103 is used to determine the display mode, and a flag indicating the folder display mode is set as an initial value.

When the folder display mode is selected,
Proceeding to step S802, folder management display processing is performed. In this process, the folders and the images belonging to the folders are displayed on the display unit 113. For example, as shown in FIG. 12, each registered folder 1101 is displayed on the display unit 11.
In a third area 1101, thumbnail images of images belonging to one selected folder among the folders 1101 and a scroll bar 1103 for scrolling the thumbnail images are arranged in an area 1102, and a plurality of function buttons are arranged in an area 1104. Is displayed. The thumbnail image region 1102 is divided into twelve regions, and one thumbnail image is displayed for each divided region. Also, 1
When the number of images belonging to one folder is 12 or more, the thumbnail images displayed in the area 1102 can be scrolled by operating the scroll bar 1103. Area 110 of this thumbnail image
When the thumbnail image displayed in 2 is selected, an image corresponding to the selected thumbnail image is displayed on the entire screen of the display unit 113.

The function buttons displayed in the area 1104 include buttons such as “MENU”,..., “Delete”, and “end”.
When a selection is made in step 2, a process corresponding to the selected function button is executed. When "end" is selected from the function buttons, the folder management display process is terminated, and the process exits the process and returns to the menu display process in step S502 shown in FIG.

If it is determined in step S801 that the time-series display mode has been selected, the flow advances to step S803 to delete the thumbnail images of the images shot in time series based on the stored time data (shooting date and time) of the images. It is displayed on the display unit 113. Here, for example, FIG.
As shown in FIG. 3, a time axis display area 1106 is provided,
The time axis display area 1106 includes a time axis 11 on which a scale 1106d of the selected time unit (year, month, day) is engraved.
06b (scale) is displayed. This time axis 1106
The scale 1106d of b is engraved so as to send time downward. In this example, the daily scale (from February 27 to 3)
Until March 7). Reference time data of a unit larger than the current scale unit engraved on the time axis 1106b is displayed in the area 1106a. When a point 1106c on the time axis 1106b is designated by pen input, a time corresponding to the designated point 1106c (March 1, 2000 in this example) is displayed in the area 1105. A thumbnail image of an image after the time set by the designated point 1106c is read from the data storage unit 104 and displayed in the area 1102, and a scroll bar 1103 is displayed. Each function button is displayed in area 1104.

Then, the flow advances to step S804 to determine, with reference to the coordinate data stored in the coordinate storage area 103e of the RAM 103, whether or not there is a pen input while the screen is displayed. Here, if there is no pen input, the process waits until there is a pen input, and if there is a pen input, the process proceeds to step S805. In step S805, it is determined whether or not the pen input is pen-up data. If the pen input is pen-up data, step S806 is performed.
Then, the scale change mode flag stored in the flag area 103f of the RAM 103 is reset. That is, the scale change mode described later is canceled. Then, the process returns to step S804 again.

On the other hand, if the pen input is not pen-up, the flow advances to step S807 to determine whether the pen input is a pen continuous input. If the pen input is not a continuous input, step S8 shown in FIG.
Proceed to 13. If the pen input is a continuous input, the process proceeds to step S808, and the flag area 103 of the RAM 103
It is determined whether the scale change mode is set by referring to the scale change mode flag stored in f. The scale change mode is a mode for changing the time unit of the scale 1106d of the time axis 1106b, and the time unit is set to be changeable within a predetermined range such as between year, month, and day units. ing. If the scale change mode has not been set, the process returns to step S804.

If the scale change mode has been set, the flow advances to step S809 to determine whether or not this pen input is a continuous input corresponding to the scale change mode. In the present embodiment, the coordinates of the designated point by pen input are (Xp, Yp), the coordinates of the current designated point 1101c are (Xup, Yup), and the following equation (3) is used between the X coordinates of each point. It is determined whether or not this pen input is a continuous input corresponding to the scale change mode according to whether or not the relationship shown in (1) is established. That is, it is determined whether or not the pen input is a continuous input corresponding to the scale change mode according to whether or not the input pen 202 has been moved in the X direction.

Xup ≠ Xp (3) When this relationship is not established, that is, when the coordinates Xup and Xp are equal, it is determined that the pen input is not a continuous input (continuous input in the X direction) corresponding to the scale change mode. Then, the process returns to step S804. When the relationship of the above formula (3) is established, it is determined that the pen input is a continuous input corresponding to the scale change mode, and the process proceeds to step S810, where the relationship shown in the following formula (4) is established between the X coordinates. It is determined whether or not.

Xup <Xp (4) When this relationship is established, it is determined that the scale is enlarged in the scale change mode, and the flow advances to step S811 to set the time unit of the scale 1106d of the time axis 1106b to the currently set time. The time axis 1106b is displayed in a unit smaller than the unit. Then, again at step S
Return to 802. On the other hand, when the relationship of the above equation (4) does not hold, it is determined that the scale is reduced in the scale change mode, and the flow advances to step S812 to set the time unit of the scale 1106d of the time axis 1106b to the currently set time. Change the unit to a larger unit than the time axis 11
06b is displayed. Then, the above step S802 is repeated.
Return to

Specifically, in the time axis display area 1106 in which the scale change mode is set as shown in FIG. 14A, when the input pen 202 is moved rightward in the continuous input state with the designated point 1106c as a starting point, this continuous Enlargement of scale by input, ie, scale unit 11 of time axis 1106b
06d is changed from month to day with the designated point 1106c as the center. After changing the scale unit, FIG.
As shown in (d), a time axis 1106b engraved with a day scale 1106d is displayed.
The display position and the designated time of 106c are held in the state before the change. In addition, the day “01” of the designated point 1106c
"200" as information to indicate the year and month
"0.03" (March 2000) is displayed in the area 1106a. By the time the scale unit changes to the time unit of the day, it is assumed that the scale unit changes stepwise to the circumferential unit and the two-day unit according to the continuation of the continuous input. Here,
The progress status is omitted.

In the time axis display area 1106 in which the scale change mode is set as shown in FIG.
When the input pen 202 is moved leftward in the continuous input state with the designated point 1106c as a starting point, the scale is reduced by the continuous input, that is, the scale unit 1106 of the time axis 1106b.
d is changed from a unit of one month to a unit of two months (bimonthly) around the designated point 1106c. After the change of the scale unit, as shown in FIG.
A time axis 1106b engraved with 06d is displayed, but the display position and the designated time of the designated point 1106c, which is the starting point, are held in the state before the change. Also, the time axis 11
“2000” and “2001” are information in the area 110 as information for indicating the year of the scale 1106d of 06c.
6a. When the continuous input is further continued, a stepwise change to a larger scale unit is performed. Finally, as shown in FIG. 14D, the scale unit 1106d of the time axis 1107b is changed to a unit of February (bimonthly). Is changed to yearly. As described above, the scale unit is changed by the continuous input. When the continuous input is completed, the scale change mode flag is reset in step S806, so that the scale change mode ends at this point. In the present embodiment, the maximum scale unit of the time axis 1106b is set to one year unit, but a plurality of year units such as two year units may be set to the maximum scale unit.

If it is determined in step S807 that the pen input is not a continuous input, the flow advances to step S813 shown in FIG. In step S813, the RAM
The scale change mode flag in the flag area 103f of 103 is reset, and in the subsequent step S814, the coordinates input by pen input are determined. If the input coordinates are the coordinates (Xup, Yup) of the designated point 1106c, the flow advances to step S815 to set a scale change mode flag in the flag area 103f of the RAM 103, and then to change the mode in step S816. The display of the designated point 1106c is changed so as to inform the operator. For example, as shown in FIG.
The display of the designated point 1106c is changed by encircling 6c. Then, the process returns to step S804.

On the other hand, when the input coordinates are the designated point 11
If it is in the area of the time axis 1106b excluding the area of 06c, the flow advances to step S817 to determine whether or not the period search mode is set by referring to the period search mode flag in the flag area 103f of the RAM 103. here,
The period search mode is XX / XX / XX to XX / XX
This is a mode for performing data search and display for a period set as month XX day. If the period search mode has not been set, the process advances to step S818 to change the display start time. That is, the designated point 1106c is moved to a position corresponding to the input coordinates, and the display start time corresponding to the designated point 1106c after the movement is set to the display start time 1 in the RAM 103.
03g. In a succeeding step S819, it is determined whether or not there is image data having time data matching the time data stored in the display start time 103g by searching the time data of the image data stored in the data storage unit 104. judge. Here, it is assumed that the comparison of the time up to the minimum unit of the designated time is performed. For example, 1
If you specify November 2, 998,
Image data having time data in the range of 00:00:00 to 23:59:59 on January 2 is searched for as the corresponding image data. If the corresponding image data exists, the process proceeds to step S820, displays the thumbnail image of the corresponding image data on the display unit 113, and returns to step S804.

On the other hand, if it is determined in step S819 that there is no corresponding image data, the flow advances to step S821 to determine whether or not there is image data after the selected time. If no exists, the flow advances to step S824 to clear the display of the thumbnail image display area 1102, and the flow returns to step S804. When the corresponding image data exists, the process proceeds to step S822, and the time data closest to the selected time among the time data of the corresponding image data is stored in the display start time area 103g as the display start time, and in the subsequent step S823 As shown in FIG.
02, lower the brightness of the thumbnail image displayed,
Then, the process returns to step S804. Here, by lowering the brightness of the thumbnail image, it is possible to notify the operator that there is no image data corresponding to the specified time. If there is image data after the selected time, the scale 1106 on the time axis 1106b is displayed.
By changing the display mode of the scale portion where the corresponding image data exists in the day, time, etc. indicated by d, there is no image data corresponding to the specified time, but image data after the selected time exists. Can be notified to the operator. For example, as shown in FIG.
Of the days indicated by the scale 1106d of 06b, the day on which the corresponding image data exists (the 2nd and 6th days in this example) is displayed with low brightness.

If it is determined in step S817 that the period search mode has not been set, step S8
25, the display end time is stored in the display time end area 103h of the RAM 103, and the stored display end time is stored in FIG.
5 is displayed in an area 1107. In a succeeding step S826, the thumbnail image of the image data existing in the period from the display start time of the display start time area 103g to the display end time of the display end time area 103h is displayed on the display unit 113, and the process returns to the step S804.

If it is determined in step S814 that the input coordinates are in the area 1104 for displaying the function button, the flow advances to step S827 shown in FIG. 11 to determine whether the input coordinates correspond to the period for setting the period search mode. It is determined whether it is in the area of the search mode setting button (not shown). If the input coordinates are in the area of the period search setting button, the flow advances to step S828 to set a period search mode flag in the flag area 103f of the RAM 103, and in step S829, the time specified by the current specified point 1106c is set. It is stored in the display start time area 103g as the start time of the period search, and the stored time is displayed in the area 1105 in FIG. Then, the above step S804
Return to

If it is determined in step S827 that the input coordinates are not in the area of the period search mode setting button, the flow advances to step S830 to determine whether or not the input coordinates are in the area of the period search mode release button. judge. When the input coordinates are in the period search mode release button area, the process proceeds to step S831, and the period search mode flag in the flag area 103f is reset.
In a succeeding step S832, the display start time displayed in the area 1107 is changed to the currently designated time, and the process returns to the step S804. On the other hand, when the input coordinates are not in the area of the period search mode release button, the process advances to step S833 to determine whether or not the input coordinates are in the area of the folder management display button. If it is in the folder management display button area, the flow advances to step S834. In step S834, a folder management display mode flag is set in the flag area 103f, and the process returns to step S801. If the input coordinates are not in the area of the folder management display button, the flow advances to step S835 to execute processing corresponding to other buttons (deletion, menu switching, etc.), and then returns to step S804.

If the coordinates input in step S812 are in another area, the process returns to step S804 without performing any processing.

As described above, in the present embodiment, the designated point 1106c which is the starting point of the continuous input according to the direction of the continuous input
Since the scale unit of the time axis 1106b is changed and displayed centering on the position of, there is no need to perform an input operation such as resetting the designated point 1106c, and it is possible to provide a user-friendly operation environment.

In the present embodiment, an example has been described in which the time unit of the scale used for managing the photographed image is changed. However, another unit, for example, a scale on which a scale such as distance and weight is engraved is used. It goes without saying that the principle of the present invention can be applied to the change of the scale unit even when other data is managed. In the present embodiment,
Although the example of changing the scale unit of the time axis in the image data management has been described, the scale unit is similarly changed in another application (for example, schedule management) using a scale engraved with the time unit scale. It goes without saying that it is possible.

Further, in the present embodiment, the folder management display mode and the period search mode are configured to be performed independently, but they may be configured to be performed simultaneously. An example in this case will be described with reference to FIG. FIG. 16 is a diagram illustrating an example of a display screen when the electronic device in FIG. 1 is configured to simultaneously perform the folder management display mode and the period search mode.

In the case where the folder management display mode and the period search mode are simultaneously performed in the electronic device,
As shown in FIG. 16, a time axis display area 1401, an area 1402 for displaying a folder for storing image data in a time range designated on the time axis, and a thumbnail image of image data belonging to the selected folder are displayed. Area 14
03 and are displayed at the same time. Thus, the folder management display mode and the period search mode can be performed simultaneously.

In this case, first, the time is designated on the time axis to display the corresponding folder and the thumbnail image of the image data belonging to the folder, or the time is designated after selecting the folder. It is possible.

(Second Embodiment) Next, an embodiment of the present invention will be described with reference to FIG. FIG. 17 is a flowchart showing a main part of a procedure of an image reproducing process according to the second embodiment of the electronic apparatus of the present invention. In addition,
This embodiment has the same configuration as the above-described first embodiment, and a description thereof will be omitted.

This embodiment is different from the above-described first embodiment in that the change rate of the scale unit of the time axis is set according to the distance from the start point to the end point of the continuous input, and based on the set change rate. The difference is that the scale unit is changed.

Specifically, a series of processes from step S809 to step S812 shown in FIG. 9 in the first embodiment described above is replaced with a series of processes from step S1501 to step S1510 shown in FIG. .

If it is determined in step S808 that the scale change mode has been set, then in step S1501, as shown in FIG.
It is determined whether or not (the X coordinate of the start point of the continuous input) and the coordinate Xp (the X coordinate of the end point of the continuous input) satisfy the relationship of the above equation (3). When the coordinate Xup is equal to the coordinate Xp,
It is determined that the pen input is not a continuous input (continuous input in the X direction) corresponding to the scale change mode, and the process returns to step S804 (shown in FIG. 9). If the relationship of the above formula (3) is established, it is determined that the pen input is a continuous input corresponding to the scale change mode, and the flow advances to step S1502 to determine whether the relationship shown in the above formula (4) is established between the X coordinates. Determine whether or not.

When the relationship shown in the above formula (4) is established between the X coordinates, it is determined that the scale is enlarged in the scale change mode, and the flow advances to step S1503 to execute the relationship shown in the following formula (5) between the X coordinates. Is determined.

Xp−Xup> Xa (5) Here, Xa is a preset threshold value.

If the relationship of the above formula (5) is established, the enlargement rate of the scale is set to a large value in step S1505. If the relationship of the above formula (5) is not satisfied, the process proceeds to step S1504.
Use to set the scale enlargement ratio to small. That is, the enlargement ratio is set according to the distance from the start point to the end point of the continuous input. Here, the enlargement rate of this scale is defined as the time axis 110
When the time unit of the scale 1106d of 6b is changed to a unit smaller than the currently set time unit, the number of change steps per time is changed for each scale unit such as year unit, week unit, day unit, and the like. Represent. For example, when the enlargement ratio is set to a large value, the enlargement ratio is set as two stages. In the case of this enlargement ratio, when the current scale unit is a year unit, the scale unit is changed from a year unit to a day unit. It will be changed by two steps. Also, when the magnification is set to small,

The unit is changed to the unit and the time axis 1106b is displayed. The display position and the designated time of the designated point 1106c, which is the starting point, are held in the state before the change. In a succeeding step S1606, the count value Tc of the counter Tc is incremented by one, and the process returns to the step S804 (shown in FIG. 9).

On the other hand, when the relationship of the above equation (4) is not established, it is determined that the scale is to be reduced in the scale change mode, and the flow advances to step S1608. It is determined whether or not the relationship shown in the following equation (8) holds.

Tc> T (8) If the relationship of the above equation (8) is established, step S1609
Then, the scale reduction rate is set to be large, and if the relationship of the above equation (8) is not satisfied, the scale reduction rate is set to be small in step S1611. That is, like the enlargement ratio, the reduction ratio is set according to the time required for continuous input from the starting point.

When the reduction ratio is set as described above, the flow advances to step S1610 to change the time unit of the scale 1106d of the time axis 1106b to a unit larger than the currently set time unit according to the set reduction ratio. Time axis 11
06b is displayed. Note that the designated point 1106 as the starting point
