This program causes the computer to execute the process.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows the configuration of the embodiment of the present invention. The television receiver 1 includes a display unit 2 and a reception unit 3 below the display unit 2. The receiving unit 3 includes a light receiving unit 3-1 that receives an infrared signal from the remote commander 11, and a mouse receiving unit 3-2 that receives a radio wave output from the mouse 12. In other words, the television receiver 1 can control the operation when either the remote commander 11 or the mouse 12 is operated.

  FIG. 2 shows the configuration of the remote commander 11. A light emitting unit 61 that outputs an infrared signal is provided above the light emitting unit 61, and a button 62 that is operated when inputting numbers is disposed below the light emitting unit 61. Below the button 62, a memo button 63, a creation view button 64, a palette button 65, and a mode button 66 are provided.

  The memo button 63 is operated when setting the still image mode. The creation view button 64 is operated when entering the zoom mode. Each time the creation view button 64 is operated, the zoom ratio toggles in the order of 1.0, 1.5, 2.0, 2.5, 3.0, 1.0, 1.5, and so on. The palette button 65 is operated when adjusting the color. The mode button 66 is operated when setting various modes.

  A jog dial 67 is disposed below the memo button 63 to the mode button 66, and a stick 68 is disposed at the center thereof. The jog dial 67 is rotated clockwise or counterclockwise when adjusting the zoom ratio. Specifically, the jog dial 67 is rotated clockwise when the image is further enlarged, and is rotated counterclockwise when the enlargement ratio is reduced. The stick 68 can be operated in eight directions including up and down, left and right directions, and diagonally up and down 45 degrees to the right or left, and can be pressed. By operating the stick 68 in the up / down / left / right or diagonal directions, the zoomed screen can be moved in the operated direction.

  A return button 69 is arranged on the lower left side of the jog dial 67, and a menu button 70 is arranged on the lower right side thereof. The return button 69 is operated to cancel all modes such as the zoom mode and the memo mode and return to the normal screen. The menu button 70 is operated when displaying or deleting the menu.

  A volume button 71 and a channel button 72 are arranged below the return button 69 and the menu button 70. The volume button 71 is operated in the + direction when increasing the volume, and is operated in the-direction when decreasing the volume. The channel button 72 is operated in the + direction when increasing the channel number, and is operated in the-direction when decreasing the channel number.

  FIG. 3 shows the configuration of the mouse 12. Each of the left button 91 and the right button 92 can be clicked by pressing it. A wheel 93 is disposed between the left button 91 and the right button 92. The wheel 93 can rotate upward or downward in the drawing. Although illustration is omitted, the mouse has a built-in transmitter that outputs radio waves corresponding to user operations, and radio waves output therefrom are received by the receiver 3-2.

  FIG. 4 shows the internal configuration of the television receiver 1. The tuner 131 receives a television broadcast and outputs the image signal to the image quality improvement processing unit 132. The high image quality processing unit 132 includes a preprocessor 161, a signal processor 162, and an SDRAM controller 163. The preprocessor 161 adjusts the timing of the image signal supplied from the tuner 131 and outputs the image signal to the SDRAM controller 163. The SDRAM controller 163 supplies the image signal supplied from the preprocessor 161 to an SDRAM (Synchronous Dynamic Random Access Memory) 133 for storage.

  The SDRAM controller 163 also reads the image signal stored in the SDRAM 133 and stores it in the built-in frame buffer 182. The XY register 181 holds four coordinate points for designating a range to be written to or read from the SDRAM 133 based on an instruction from the microcomputer 135. The signal processor 162 performs image quality improvement processing on the image data supplied from the frame buffer 182 by increasing or decreasing the number of pixels.

  The image signal output from the signal processor 162 is supplied to the color space converter 134. The color space converter 134 converts the input image signal into a luminance signal (Y) and color difference signals (Cb, Cr), and outputs them to the display unit 2 for display. The color space converter 134 incorporates an OSD mixer 201, superimposes the OSD information supplied from the FPGA unit 136 on the image signal, and outputs it to the output unit 2 for display.

  An FPGA (Field Programmable Gate Array) unit 136 includes an OSD controller 231, an XY register 232, and an event detector 233. The XY register 232 stores a cursor operated by the remote commander 11 and a pointer position operated by the mouse 12. The event detector 233 detects an event of the mouse 12 based on the infrared signal received by the light receiving unit 3-1. The table 241 built in the OSD controller 231 stores pointer shapes. The microcomputer 135 receives the infrared signal output from the remote commander 11 and controls each unit based on the signal output from the light receiving unit 3-1.

  The image quality improvement processing unit 132, the SDRAM 133, the color space comparator 134, the microcomputer 135, and the FPGA unit 136 of the television receiver 1 generally have functional blocks that execute functions as shown in FIG. ing.

  The determination unit 301 executes various determination processes. The timekeeping unit 302 executes a timekeeping operation and outputs time information. The display unit 303 displays a predetermined image on the display unit 2. The moving unit 304 moves an image, a cursor, a pointer, and the like. The erase unit 305 erases the menu. The shape selection unit 306 selects the shape of the pointer. The changing unit 307 changes the zoom rate. The cancel unit 308 cancels the zoom mode.

  The acquisition unit 309 acquires an image signal in the writing range. The writing unit 310 writes an image signal in the SDRAM 133. The reading unit 311 reads an image signal from the SDRAM 133. The holding unit 312 holds the image signal in the frame buffer 182. The image quality improving unit 313 generates a zoom image by increasing the number of pixels of the image signal (similarly, a reduced image can also be generated). The basic processing content of the high image quality processing is disclosed in, for example, Japanese Patent Application Laid-Open Nos. 2002-218414 and 2002-196737. The mode setting unit 314 sets various modes. When the remote commander 11 or the mouse 12 is operated by the user, the execution unit 315 executes processing corresponding to the operation.

  Whether each of the determination unit 301 to execution unit 315 belongs to one of the image quality improvement processing unit 132, the color space converter 134, the microcomputer 135, and the FPGA unit 136 may correspond one-to-one. Although it may correspond to each part, it cannot be determined uniquely, but it is a function that exists in any one of the parts.

  Next, a signal reception process when the remote commander 11 or the mouse 12 is operated will be described with reference to the flowchart of FIG.

  The user operates either the remote commander 11 or the mouse 12 when operating the television receiver 1. Therefore, in step S1, the determination unit 301 determines whether a signal is received from the remote commander.

  When the user operates the remote commander 11, an infrared signal is output from the light emitting unit 61, and the infrared signal is received by the light receiving unit 3-1. The determination unit 301 can determine whether a signal is received from the remote commander 11 based on the output of the light receiving unit 3-1. When a signal is received from the remote commander 11, the execution unit 315 executes corresponding processing in step S2. That is, when the operation of the remote commander 11 is an instruction to change the channel, for example, the execution unit 315 controls the tuner 131 to change the channel to be received. Alternatively, when the instruction is to move the cursor, the execution unit 315 executes processing for moving the cursor.

  If it is determined in step S1 that no signal has been received from the remote commander, in step S3, the determination unit 301 determines whether a signal has been received from the mouse. When the user operates the mouse 12, the receiving unit 3-2 receives the radio wave output from the mouse 12. The event detector 233 detects whether an event has occurred in the mouse 12 from the output of the receiving unit 3-2. The determination unit 301 performs determination processing based on the detection result of the event detector 233. When it is determined that a signal has been received from the mouse 12, the execution unit 315 executes a corresponding process in step S4. For example, when an instruction to display a menu is given by operating the mouse 12, a process for displaying the menu is executed.

  The processing shown in the flowcharts of FIGS. 7, 8, 10, 11, 13, 14, 20, and 21 described below is the specific content of the processing in steps S <b> 2 and S <b> 4 in FIG. Part of it.

  Next, pointer display processing will be described with reference to the flowchart of FIG.

  In step S11, the determination unit 301 determines whether the mouse has been moved. This determination can be made by monitoring the detection result of the event detector 233. If it is determined that the mouse 12 has not been moved, the determination unit 301 determines in step S12 whether the wheel has been rotated. This determination can also be made by monitoring the event detection result of the event detector 233. If it is determined in step S12 that the wheel 93 is not rotated, in step S13, the determination unit 301 determines whether the mouse button has been clicked. This determination is also made based on the detection result of the event detector 233. If none of the mouse buttons (the left button 91 and the right button 92) has been clicked, the process returns to step S11, and the subsequent processes are repeatedly executed.

  That is, the processes in steps S11 to S13 are repeatedly executed until the mouse 12 is operated. If it is determined in step S11 to step S13 that the mouse 12 has been operated, in step S14, the time measuring unit 302 starts a timer. By starting the time measurement, it is possible to determine whether 5 seconds in step S22, which will be described later, or 40 seconds in step S23 has elapsed. In step S15, the display unit 303 displays a pointer. That is, whenever the mouse 12 is operated, the pointer is displayed.

  In step S16, the determination unit 301 determines whether the mouse has been moved. If the mouse 12 has been moved, the moving unit 304 moves the pointer in step S17. That is, when the user operates the mouse 12 and moves the mouse 12 in a predetermined direction, the pointer is moved in the moved direction. Next, in step S20, the timer unit 302 resets the timer. That is, the timer that started the time counting operation in the process of step S14 is reset, and the time counting operation is restarted from 0 again. Thereafter, the process returns to step S16, and the subsequent processes are repeatedly executed.

  If it is determined in step S16 that the mouse 12 has not been moved, the determination unit 301 determines in step S18 whether the wheel has been rotated. When the wheel 93 of the mouse 12 is rotated, the timer 302 resets the timer in step S20. Then, the process returns to step S16 again, and the subsequent processes are repeatedly executed.

  If it is determined in step S18 that the wheel 93 is not rotated, in step S19, the determination unit 301 determines whether the mouse button has been clicked. That is, it is determined whether the user has clicked the left button 91 or the right button 92 of the mouse 12. When the left button 91 or the right button 92 is clicked, the timer 302 resets the timer in step S20. And a process returns to step S16 and the process after it is repeatedly performed.

  The processing executed when the wheel 93 is rotated or the left button 91 or the right button 92 is operated is not described here. For example, steps S43 and S44 in FIG. 8, steps S64 in FIG. S65, S67, S68, steps S150 and S152 in FIG. 14, steps S162, S163, S165, and S166 in FIG. 20, and steps S187, S189, and S191 in FIG. . Here, only the display of the pointer will be described.

  Thus, every time the mouse 12 is operated, the operation of resetting the timer is repeated. If it is determined in step S19 that the mouse button has not been clicked, in step S21, the determination unit 301 determines whether a menu is displayed. When the menu is displayed, in step S23, the determination unit 301 determines whether 40 seconds have elapsed. That is, it is determined whether or not 40 seconds have elapsed since the timer was started in step S14 or the timer was reset in step S20 and the timing operation was started again. If 40 seconds has not elapsed, the process returns to step S16, and the subsequent processes are repeatedly executed.

  If it is determined in step S21 that the menu is not displayed, in step S22, the determination unit 301 determines whether 5 seconds have elapsed. If it is determined that 5 seconds have not yet elapsed, the process returns to step S16, and the subsequent processes are repeatedly executed.

  If it is determined in step S23 that 40 seconds have elapsed, or if it is determined in step S22 that 5 seconds have elapsed, in step S24, the deletion unit 305 deletes the pointer. That is, when the menu is displayed, the pointer is erased when 40 seconds elapse without any operation of the mouse 12. On the other hand, when the menu is displayed, when the mouse 12 is not operated and five seconds elapse, the pointer is deleted at that time. Thereafter, the process returns to step S11, and the subsequent processes are repeatedly executed.

  In this way, when the mouse 12 is operated in any way, a pointer is displayed at that time, and after the pointer is displayed, the mouse 12 is operated until 40 seconds have elapsed with the menu displayed. If not, the pointer is erased. Similarly, when the menu is not displayed, the pointer is deleted if the mouse 12 is not operated for 5 seconds.

  In this way, when a television video image is displayed, unnecessary pointers are prevented from being displayed, making it difficult to view the image. However, when the menu is displayed, there is a possibility that the menu may be operated, so that a long time until deletion is set.

  In the embodiment of the present invention, the shape of the pointer is changed according to circumstances. The processing for changing the shape of the pointer will be described with reference to the flowchart of FIG.

  In step S41, the shape selection unit 306 determines whether the pointer is positioned on the zoom image (as will be described later with reference to FIG. 10), when the creation view button 64 is operated, the zoom image is displayed. ). If the pointer is not positioned on the zoom image, in step S42, the shape selection unit 306 selects a pointer having an arrow shape. That is, the pointer 331 shown in FIG. 9A is selected. Specifically, a cursor 331 having an arrow shape (FIG. 9A), a gripped hand shape (FIG. 9B), or an open hand shape (FIG. 9C) shown in FIG. 9 is stored in the table 241; One of them is selected and supplied to the OSD mixer 201 of the color space converter 134. The OSD mixer 201 superimposes a pointer having a shape selected from the table 241 on the image, and outputs the pointer to the display unit 2 for display.

  If it is determined in step S41 that the pointer is not located on the zoom image, in step S43, the determination unit 301 determines whether the left click has been performed. When the left button 91 of the mouse 12 is operated (left-clicked), in step S44, the shape selection unit 306 selects the pointer of the shape of the gripped hand. That is, the pointer 331 having the shape of the grasped hand shown in FIG. 9B is selected. Similarly to the case in step S42, the pointer 331 having this shape is selected from the table 241, superposed on the image in the OSD mixer 201, output to the display unit 2, and displayed.

  If it is determined in step S43 that the left click has not been performed, in step S45, the shape selection unit 306 selects a pointer having the shape of an open hand. Specifically, an open hand-shaped pointer 331 shown in FIG. 9C is selected, superimposed on the image by the OSD mixer 201, output to the display unit 2, and displayed.

  In the present embodiment, the user can enlarge (zoom) the moving image received by the tuner 131 and displayed on the display unit 2 in real time. When zooming the moving image, the user operates the creation view button 64 of the remote commander 11. In step S61, the determination unit 301 determines whether the creation view button has been operated. When the creation view button 64 is operated, in step S62, the changing unit 307 changes the zoom rate by one step. That is, the zoom ratio changes in a toggle shape every time the creation view button 64 is operated, such as 1.0, 1.5, 2.0, 2.5, 3.0, 1.0. When the creation view button 64 is operated once, the zoom ratio is changed from the current value to the next value to a value larger by one step.

  When the zoom rate is designated in this way, a moving image having a predetermined zoom rate generated by the signal processor 162 is displayed on the display unit 2 in real time, as will be described later with reference to FIG. 11 or FIG. The

  If it is determined in step S61 that the creation view button 64 has not been operated, the determination unit 301 determines in step S63 whether the jog dial has been operated. When the jog dial 67 is operated, in step S64, the changing unit 307 changes the zoom rate corresponding to the operation amount. Specifically, when the jog dial 67 is rotated counterclockwise, the zoom ratio is sequentially changed to a small value such as 3.0, 2.5, 2.0, 1.5, 1.0, and 3.0 according to the amount of rotation. . On the other hand, when the lens is rotated in the clockwise direction, the zoom ratio is changed step by step in increments of 1.0, 1.5, 2.0, 2.5, 3.0, 1.0 in accordance with the amount of rotation. .

  If it is determined in step S63 that the jog dial 67 has not been operated, the determination unit 301 determines in step S65 whether the wheel has been operated. When the wheel 93 of the mouse 12 is operated, the changing unit 307 changes the zoom rate in accordance with the operation amount of the wheel 93 in step S64. The rotation amount of the jog dial 67 and the rotation amount of the wheel 93 are set so as to correspond to each other.

  If it is determined in step S65 that the wheel 93 has not been operated, the determination unit 301 determines in step S66 whether the stick has been operated. If the stick 68 is operated, the moving unit 304 moves the image corresponding to the operation direction in step S67. That is, when the user operates the stick 68 in the up / down / left / right or upper right, lower right, upper left, or lower left direction, a process of moving the image in the operated direction is executed.

  If it is determined in step S66 that the stick 68 has not been operated, the determination unit 301 determines in step S68 whether the left drag has been performed. When the left drag is performed, similarly, in step S67, the moving unit 304 moves the image corresponding to the operation direction. That is, when the user presses the left button 91 of the mouse 12 (as described with reference to FIG. 8, the pointer changes from the shape of the open hand (FIG. 9C) to the shape of the gripped hand (FIG. 9B). For example, when the image is moved in the right direction, the image is moved in the right direction. If it is determined in step S68 that the left drag is not performed, in step S69, the determination unit 301 determines whether the return button has been operated. If the return button 69 is operated, the cancel unit 308 cancels the zoom mode in step S70. As a result, a normal size moving image is displayed again. When the processes of steps S62, S64, S67, and S70 are completed, or when it is determined in step S69 that the return button 69 has not been operated, the zoom instruction process is terminated.

  When the zoom instruction process is performed as described with reference to the flowchart of FIG. 10, next, as shown in FIG. 11 or FIG. 13, a zoom image generation process is performed. One of the zoom image generation processes in FIGS. 11 and 13 is executed. The zoom image generation process in FIG. 11 is a method in which only a necessary range of image data for one frame is written in the SDRAM 133, whereas FIG. 13 shows the image data for one frame written in the SDRAM 133. Of these, only the necessary range is read.

  First, the zoom image generation process of FIG. 11 will be described. In step S81, the acquisition unit 309 acquires the writing range. This writing range is written in the XY register 181 in advance by the microcomputer 135, and the acquisition unit 309 acquires the writing range by reading the value of the XY register 181. In step S82, the writing unit 310 writes image data to the SDRAM. That is, the SDRAM controller 163 writes the acquired range of image data in the SDRAM 133 out of the image data output from the tuner 131 and input via the preprocessor 161 at a necessary timing. That is, only the image data in the specified range is written into the SDRAM 133. In step S83, the reading unit 311 reads image data from the SDRAM.

  For example, as shown in FIG. 12, the memory area of the SDRAM 133 is a range indicated by a frame 351. When the actual image size is the size indicated by the frame 352 and the range indicated by the frame 353 is designated as the writing range, the image data in the range indicated by the frame 353 is written to the SDRAM 133. become. In step S83, the image data in the range of the frame 353 is read out.

  In step S84, the holding unit 312 holds the image data read in step S83 in the frame buffer in step S84. That is, the SDRAM controller 163 causes the frame buffer 182 to hold the image data in the range indicated by the frame 353 read from the SDRAM 133. Next, in step S85, the determination unit 301 determines whether or not all image data has been retained. If there is image data that has not yet been retained, the process returns to step S84 until all image data is retained. Steps S84 and S85 are repeated. If it is determined in step S85 that all the image data has been retained (when all the image data in the range indicated by the frame 353 has been stored in the frame buffer 182), in step S86, the image quality improving unit 313 displays the high image quality. Process.

  That is, the signal processor 162 performs image quality improvement processing based on the image data in the range of the frame 353 stored in the frame buffer 182. Specifically, the number of pixels is increased by determining a class as an image feature from a predetermined pixel in the vicinity of the target pixel and processing the image data based on a prediction coefficient corresponding to the class. Can be reduced or decreased. By using a prediction coefficient generated by learning many images in advance, a higher-quality zoom image can be generated.

  This zoom image is output to the display unit 2 via the color space converter 134 and displayed.

  Next, the zoom image generation process shown in the flowchart of FIG. 13 will be described. In this case, in step S101, the writing unit 310 writes image data to the SDRAM. At this time, the SDRAM controller 163 writes all image data for one frame supplied from the tuner 131 via the preprocessor 161 to the SDRAM 133. In step S102, the acquisition unit 309 acquires a read range. That is, the information of the read range written in the XY register 181 is read. In step S103, the reading unit 311 reads image data from the SDRAM. That is, in this case, since all the image data for one frame in the range indicated by the frame 352 in FIG. 12 is stored in the SDRAM 133, in step S103, the image data in the necessary range indicated by the frame 353 in FIG. Only read out.

  In step S104, the holding unit 312 holds the image data in the frame buffer. That is, the image data in the range indicated by the frame 353 in FIG. 12 read in step S103 is held in the frame buffer 182. In step S105, the determination unit 301 determines whether all the image data has been retained. If there is image data that has not yet been retained, the process returns to step S104, and the subsequent processing is repeatedly executed. If it is determined in step S105 that all image data has been retained, in step S106, the image quality improving unit 313 performs image quality improving processing. The details of this process are the same as the process of step S86 in FIG.

  Compared with the process of FIG. 13, the process of FIG. 11 can write and read image data more quickly.

  In this embodiment, the user can display a menu by operating the remote commander 11 or the mouse 12. The menu display process will be described with reference to the flowchart of FIG.

  In step S131, the determination unit 301 determines whether the pointer has entered from the outside to the inside of the designated area. If it is determined that the pointer is not inside from the outside of the designated area, in step S140, the determination unit 301 determines whether the menu button has been operated. The user operates the menu button 70 when operating the remote commander 11 to display a menu. If the menu button 70 is operated, in step S141, the determination unit 301 determines whether a menu is displayed. If the menu is not displayed, the time measuring unit 302 starts a timer in step S144. That is, the time counting operation is started here. In step S145, the display unit 303 displays the menu together with the cursor at a predetermined position.

  15 and 16 show examples of display in this case. That is, as shown in FIG. 15, in this case, the menu 381 is displayed so as to pop out from the lower right to the left of the screen 371, and finally the menu 381 is displayed at the lower right of the screen 371 as shown in FIG. The whole is displayed.

  On the left side of the menu 381, icons 401 to 403 as first options are displayed. The icon 401 positioned at the top of the icons 401 to 403 is selected by the cursor 391 as a default. For this reason, the options 411 to 415 as the second options are displayed on the right side of the icons 401 to 403. Among the options 411 to 415 for the DRC-MF mode, DRC-MF palette, image quality mode, wide switching, and aspect ratio, the image quality mode option 413 is selected as a default, so that the option 413 is displayed. A cursor 392 is arranged.

  If it is determined in step S141 that the menu is displayed, that is, if the menu button 70 is operated but the menu is already displayed, in step S151, the timer 302 resets the timer. That is, when the menu is displayed, the timer should be started in steps S144 and S138, and the timer is reset here. Next, in step S152, the erasure unit 305 erases the menu. That is, when the menu button 70 is operated while the menu is displayed, the menu 381 is deleted.

  If it is determined in step S140 that the menu button 70 has not been operated, the determination unit 301 determines in step S142 whether the stick has been operated. When the stick 68 of the remote commander 11 is operated, in step S143, the determination unit 301 further determines whether a menu is displayed. If the menu is not displayed, in step S144, the time measuring unit 302 starts a timer, and in step S145, the display unit 303 executes processing for displaying the menu together with the cursor at a predetermined position. That is, as described with reference to FIGS. 15 and 16, the menu 381 is displayed. In other words, in this embodiment, the menu 381 is displayed not only when the menu button 70 is operated but also when the stick 68 is operated.

  If it is determined in step S143 that the menu is displayed, the moving unit 304 moves the cursor in step S146. That is, the cursor is moved in the direction in which the stick 68 is operated. Thereby, the user can move the cursors 391 and 392 on the menu 381 to a predetermined option.

  If it is determined in step S142 that the stick 68 has not been operated, in step S147, the determination unit 301 determines whether a menu is displayed. If the menu is displayed, the determination is performed in step S148. The unit 301 further determines whether the return button 69 has been operated. When the return button 69 is operated, the timer is reset in step S151, and the menu is deleted in step S152.

  If it is determined in step S148 that the return button 69 has not been operated, in step S149, the determination unit 301 determines whether a predetermined time has elapsed without operating the menu. That is, the time is measured in a state where the menu is displayed by the time measuring unit 302, and it is determined here whether or not the time has exceeded a predetermined time. If the predetermined time has elapsed, the timer is reset in step S151, and the menu is deleted in step S152.

  That is, in the state where the menu is displayed, the menu is deleted when the return button 69 is operated or when a certain time or more has passed without any operation.

  If it is determined in step S149 that the menu has not been operated and a certain period of time has not yet elapsed, in step S150, the determination unit 301 determines whether a left click has been performed outside the menu display area. That is, when the left button 91 of the mouse 12 is operated while the pointer 331 is positioned on the menu 381, it is determined that the left button 91 is clicked. In step S151, the timer 302 resets the timer, and in step S152. The display unit 303 deletes the menu. Thus, in this embodiment, the menu can be deleted by left-clicking the mouse 12.

  If it is determined in step S147 that the menu is not displayed, the processes in steps S148 to S152 are skipped. If it is determined in step S150 that the left click is not performed outside the menu display area, the processes in steps S151 and S152 are skipped.

  As shown in FIG. 17, when the pointer 331 is moved from the position shown as the pointer 331A to the position shown as the pointer 331B, that is, between the outermost part of the screen 371 and the frame 372 slightly inside it. When the pointer 331 is moved to the designated area 373 that is a narrow area, it is determined in step S131 that the pointer has entered from the outside to the inside of the designated area. At this time, in step S132, the determination unit 301 determines whether a menu is displayed. If the menu is not displayed, in step S133, the determination unit 301 determines whether the previous pointer position is stored. That is, when the menu is displayed, when the menu is deleted, the position of the pointer and the cursor is stored in step S137 as will be described later. When the previous pointer position is not stored, that is, when an operation as shown in FIG. 17 is performed for the first time and the menu is displayed for the first time, the timer 302 starts the timer in step S138. In step S139, the display unit 303 executes processing for displaying the menu together with the pointer from the initial position.

  In this way, for example, as shown in FIGS. 18 and 19, the menu 381 is displayed. First, as shown in FIG. 18, the menu 381 is displayed so as to jump out from the lower right of the screen 371 to the left, and finally displayed at the lower right of the screen 371 of the menu 381 as shown in FIG. Is done.

  A cursor 391 is displayed on the icon 401 as a default among the icons 401 to 403 as the first option, but no cursor is displayed on the options 411 to 415 as the second option. Instead, the pointer 331 is displayed on the option 413 as a default. Thereby, the user can quickly select and instruct a desired option.

  As described above, in this embodiment, when the menu 381 is displayed by operating the remote commander 11, the cursor 392 is displayed at the default position as shown in FIG. When the menu 381 is displayed by operating 12, the pointer 331 is displayed as shown in FIG. This improves operability.

  In the example of FIGS. 18 and 19, since the final selection is completed only after selecting two options, the cursor 391 is displayed at the default position on the first option. When the selection is finally completed only by selecting an option, when the menu 381 is displayed by operating the mouse 12, the pointer 331 is displayed on the one default option.

  If it is determined in step S132 that the menu has already been displayed, in step S137, the holding unit 312 stores the position of the pointer and the cursor. For example, as shown in FIG. 19, in the state where the menu 381 is displayed, when the pointer 331 is arranged on the designated area 373, the position of the arranged pointer 331 and the menu 381 at that time are displayed. The positions of the cursors 391 and 392 are stored. In step S151, the time measuring unit 302 resets the timer, and in step S152, the display unit 303 deletes the menu.

  That is, as shown in FIG. 19, the user moves the pointer 331 to a predetermined position on the designated area 373 while the menu 381 is displayed, so that the position is stored and the menu 381 is deleted. can do.

  If it is determined in step S133 that the previous pointer position is stored, the reading unit 311 reads the cursor and pointer positions in step S134. That is, as described above, when the menu 381 is deleted by operating the mouse 12 last time (by moving the pointer 331 in the designated area 373) in step S137, the position at the time of deletion is read. In step S135, the time measuring unit 302 starts a timer. In step S136, the display unit 303 displays the menu 381 together with the pointer 331 from the position read in step S134.

  That is, when the user deletes the menu 381 by moving the pointer 331A in the designated area 373, for example, in the upper right direction of the screen in FIG. 17, the user enters the screen 371 from that position (upper right of the screen 371). Then, the menu 381 is displayed.

  In this embodiment, one frame of a moving image can be temporarily displayed as a still image. The memo process for realizing this function will be described with reference to the flowchart of FIG.

  In step S161, the determination unit 301 determines whether the memo button of the remote commander has been operated. When the memo button 63 of the remote commander 11 is operated, the mode setting unit 314 sets the still image mode in step S162. Specifically, the microcomputer 135 prohibits updating of the image data stored in the frame buffer 182. The signal processor 162 repeatedly performs image quality improvement processing on the image data of the same frame, and outputs the image data to the display unit 2 via the color space converter 134 for display. Thereby, the image at the timing when the user operates the memo button 63 is displayed on the display unit 2 as a still image.

  If it is determined in step S161 that the memo button 63 of the remote commander 11 has not been operated, in step S163, the determination unit 301 determines whether the right click has been performed. When the right button 92 of the mouse 12 is clicked (when the right button is clicked), in step S164, the determination unit 301 determines whether the current still image mode is selected. If the current mode is not the still image mode, the mode setting unit 314 sets the still image mode in step S162. That is, as in the case where the memo button 63 of the remote commander 11 is operated, the still image mode is set and the still image is displayed on the display unit 2 when the right button 92 of the mouse 12 is operated.

  If it is determined in step S163 that the right click has not been performed, in step S165, the determination unit 301 determines whether the return button of the remote commander has been operated. When the return button 69 is operated, in step S166, the canceling unit 308 cancels the still image mode set in the process of step S162. As a result, the prohibition of updating the frame buffer 182 is released, and new frame image data is written to the frame buffer 182 again each time. As a result, a moving image is displayed on the display unit 2.

  Even when it is determined in step S164 that the current mode is the still image mode, a process for canceling the still image mode is also executed in step S166. That is, in this embodiment, when the memo button 63 of the remote commander 11 or the right button 92 of the mouse 12 is operated, the still image mode is set and the return button 69 of the remote commander 11 is operated, When the 12 right button 92 is operated again, the still image mode is canceled.

  The memo button 63 of the remote commander 11 is made to correspond to the left button 91 among the buttons of the mouse 12, and the return button 69 is made to correspond to the right button 92, but the reverse is also possible. In this case, each time the left button 91 is clicked, the still image mode is set and canceled.

  In the embodiment of the present invention, input using the menu 381 is possible by operating either the remote commander 11 or the mouse 12 while the menu 381 is displayed. The command reception process at the time of menu display that realizes this function will be described with reference to the flowchart of FIG.

  In step S181, the determination unit 301 determines whether a menu is displayed. When the menu 381 is not displayed, the following processing is skipped. That is, the following processing is executed only when the menu 381 is displayed.

  If it is determined in step S181 that the menu 381 is displayed, the determination unit 301 determines in step S182 whether the remote commander has been operated. When the remote commander 11 is operated, in step S183, the determination unit 301 determines whether the cursor is displayed (whether the displayed menu is a menu displayed by operating the menu button 70). To do. As described with reference to the flowchart of FIG. 14, when the menu 381 is displayed by operating the menu button 70 of the remote commander 11, the cursors 391 and 392 are displayed on the menu 381 (step S140). , S141, S144, S145). In this state, if the remote commander 11 is further operated, the execution unit 315 executes processing corresponding to the operation in step S184. For example, when the stick 68 of the remote commander 11 is operated upward, the cursor 392 in FIG. When the stick 68 is operated downward, the cursor 392 is moved onto the next lower option 414. Further, for example, when the stick 68 is pressed in a direction perpendicular to the remote commander 11, the selection of the option 413 is confirmed. That is, in the case of the display example in FIG. 16, the selection of the image quality mode is confirmed. As described above, in response to the operation of the remote commander 11, corresponding processing such as movement of the cursor and confirmation of processing is executed.

  On the other hand, as described with reference to the flowchart of FIG. 14, when the menu 381 is displayed by operating the mouse 12 and moving the pointer into the designated area 373, the pointer 331 is displayed. (Steps S131, S133, S136, S139 in FIG. 14), and the cursor 392 is not displayed (FIG. 19). Note that the cursor in the determination in step S183 means a cursor for selecting the last stage option. Therefore, the cursor 391 in FIG. 19 is not a cursor here. When it is determined in step S183 that the cursor is not displayed (when the menu 381 is displayed by operating the mouse 12), the erasure unit 305 erases the pointer in step S185. In step S186, the display unit 303 displays a cursor on the menu option closest to the position of the erased pointer.

  For example, as shown in FIG. 19, when the remote commander 11 is operated in a state where the menu 381 and the pointer 331 are displayed, the option closest to the option for which the pointer 331 is displayed (option 413). A cursor 392 is displayed above. That is, when the remote commander 11 is operated in the display state as shown in FIG. 19, the display state is as shown in FIG.

  If it is determined in step S182 that the remote commander 11 has not been operated, the determination unit 301 determines in step S187 whether the mouse has been operated. When the mouse 12 is operated, in step S188, the determination unit 301 determines whether a pointer is displayed (whether the displayed menu is a menu displayed by operating the mouse 12). As described with reference to the flowchart of FIG. 14, when the menu 381 is displayed by operating the mouse 12 and moving the pointer 331 into the designated area 373, the pointer 331 is displayed. In this case, since the user operates the mouse 12 to display the menu 381, and the mouse 12 is further operated, it is considered that the user selects an option on the menu 381 by operating the mouse. . Therefore, in step S189, the execution unit 315 executes a corresponding process.

  For example, in the state shown in FIG. 19, when the mouse 12 is moved upward, the pointer 331 is moved upward, and when it is moved downward, the pointer 331 is moved downward. The When the left button 91 is clicked on the moved previous option, the selection of the option is processed as confirmed. That is, similar to the processing corresponding to the operation of the remote commander 11 in step S184, when the mouse 12 is operated, processing such as movement of the pointer and confirmation of selection is executed in response to the operation.

  As described above, when the menu 381 is displayed by operating the remote commander 11, the cursor 392 is displayed and the pointer 331 is not displayed. In this case, in step S190, the erasure unit 305 erases the cursor. In step S191, the display unit 303 displays a pointer on the menu option closest to the deleted cursor position.

  For example, as shown in FIG. 16, when the mouse 12 is operated while the menu 381 is displayed by operating the remote commander 11, the cursor 392 positioned on the option 413 at the bottom is displayed. The pointer 331 is displayed at the position closest to the option 413 (on the option 413). That is, when the mouse 12 is operated from the display state as shown in FIG. 16, the display state is changed as shown in FIG.

  If the remote commander is operated again in the state where the cursor is displayed after the pointer is deleted in steps S185 and S186, the processing corresponding to the operation of the remote commander is executed by the processing of steps S182, S183, and S184. Will be.

  Similarly, if the user further operates the mouse 12 after displaying the pointer after deleting the cursor in the processes of steps S190 and S191, the process of steps S182, S187, S188, and S189 corresponds to the operation of the mouse 12. Will be executed.

  As described above, when the remote commander 11 is further operated after the remote commander 11 is operated to display the menu 381, processing corresponding to the operation is executed and the mouse 12 is operated. If the mouse 12 is further operated while the menu 381 is displayed, processing corresponding to the operation is executed. Conversely, even when the mouse 12 is operated in a state where the menu 381 is displayed by operating the remote commander 11, the corresponding processing can be executed, and the menu 381 is displayed by operating the mouse 12. Even when the remote commander 11 is operated in this state, the corresponding process can be executed.

  Therefore, it is possible to prevent the user from wondering which of the mouse 12 and the remote commander 11 is operated. As a result, operability is improved.

  The series of processes described above can be executed by hardware or can be executed by software. In this case, for example, the image processing apparatus is configured by a personal computer as shown in FIG.

  In FIG. 22, a CPU (Central Processing Unit) 521 executes various processes according to a program stored in a ROM (Read Only Memory) 522 or a program loaded from a storage unit 528 to a RAM (Random Access Memory) 523.

  When the above-described series of processing is executed by software, various functions can be achieved by installing a program that constitutes the software in a dedicated hardware or by installing various programs. For example, a general-purpose personal computer that can be executed is installed from a network or a recording medium.

  As shown in FIG. 22, the recording medium is distributed to provide a program to the user separately from the main body of the apparatus, and includes a magnetic disk (including a floppy disk) on which the program is recorded, an optical disk (CD- It is not only composed of a removable medium 531 composed of ROM (compact disk-read only memory), DVD (digital versatile disk), magneto-optical disk (including MD (mini-disk)), or semiconductor memory. The program is configured by a ROM 522 in which a program is recorded, a hard disk included in the storage unit 528, and the like provided to the user in a state of being incorporated in the apparatus main body in advance.
