Description

  The present invention relates to an image processing apparatus having a function of storing and reproducing image processing conditions for an input image signal, and a display apparatus using the image processing apparatus.

  In recent years, various image formats have been used. For example, various signals such as NTSC, S terminal, D terminal, etc. are used for images related to various resolutions by analog RGB or DVI and video related to personal computers. These various image signals have respective resolutions, and image processing is indispensable in order to perform display on a display device having a single resolution. For this reason, the form of the input image signal is specified, the conditions for performing the corresponding image processing are selected and implemented, and the image processing conditions set by the user are stored in combination with the form of the input signal, By calling this, video equipment that ensures convenience has been proposed.

  Specifically, in the prior art, when adjustment data corresponding to the input image signal connected by the user is stored even when used by an unspecified number of users, the stored adjustment data is not stored. Adopted. Since the number of users is unspecified, in many cases, the optimum adjustment data for the same input image signal is expected to differ depending on the user, and the stored adjustment data is not necessarily optimum. Absent.

  In the prior art, adjustment data that has been changed by different users as necessary for the same input image signal is updated and stored in the apparatus each time it is changed. If the adjustment data is different from the one desired by the user, it will be necessary to adjust it again. However, the stored adjustment data is likely to have different contents each time. Changing to adjustment data is very cumbersome and is highly likely to be set incorrectly.

  The present invention has been made in view of the above, and aims to facilitate setting of image processing conditions in an image processing apparatus shared by an unspecified number of users and a display apparatus using the same. Yes.

Since the image setting condition corresponding to the image form specified by the image detection means is selected from the first and second storage means so as to select the condition, the second setting by the user setting is performed. Since the selection is made when the condition is updated, there is an effect that convenience is improved. Furthermore, by default, the first condition that is an image setting condition prepared for each image form is selected in advance, and the same image processing condition is always set initially, so the image processing condition is reset. The amount of work to be performed is reduced, and the convenience is improved.

  According to the invention of claim 7, when there is an overwrite update to the second storage means, the second condition is selected, and when there is no overwrite update to the second storage means, the first condition is selected. Since the image setting condition corresponding to the input port detected by the port switching detection means is selected from the first and second storage means so as to select the condition, the second condition is set by the user. Since the selection is performed when is updated, there is an effect that convenience is improved. Furthermore, by default, the first condition that is an image setting condition prepared for each input port is selected in advance, and the same image processing condition is always set initially, so the image processing condition is reset. The amount of work to be performed is reduced, and the convenience is improved. In addition, since the setting condition is overwritten in the second storage means, the required storage capacity is small compared to the conventional example in which a plurality of image processing conditions associated with frequency, time, program, and the like are held. Play.

  Exemplary embodiments of an image processing apparatus and a display apparatus using the same according to the present invention will be explained below in detail with reference to the accompanying drawings.

(First embodiment)
FIG. 1 is a block diagram showing a configuration of an image processing apparatus 1 and a display apparatus 2 using the same according to the first embodiment of the present invention. Here, a case where there are three input ports is shown as an example.

  The input port 10 has three first input ports 100, a second input port 101, and a third input port 102. In this case, each input port 100 to 102 is input with an image signal of an arbitrary image format (images with different resolution, number of scanning lines, number of effective pixels in the scanning line, vertical / horizontal synchronization signal conditions, etc.). It will be described as being done. Of the image signals input to the input ports 100 to 102 (hereinafter referred to as input image signals), an input image signal to be displayed is selected by an image selection means (input port selection means) 11. As the image selection means 11, a multiplexer, a selector, or the like can be used. For example, based on the input from the external input 13 such as a switch, a multiplexer is used to select one of the three input ports 100 to 102 and input it to the image processing means 15.

  An external input 13 such as a switch is connected to the image selection means 11 for selecting the input port 10 and is connected to the image processing means 15 for setting in image processing. Further, the storage contents of the condition 2 storage means 121 described later are set by using an external input 13 such as a switch. Note that the external input 13 such as a switch is used here, but instead of the external input 13 such as a switch, the external remote controller (IR, wireless, etc.) receiving unit and the input from the receiving unit are recognized and corresponding signals are output. There may be provided remote control receiving means having a function to do this. In this case, the user switches the input port by operating the remote controller.

  The input image signal selected by the image selection unit 11 is processed by the image detection unit 14 by, for example, resolution, number of scanning lines, number of effective pixels in the scanning line, vertical / horizontal synchronization signal conditions (pouch, period of synchronization signal, etc.) ) Etc., the form of the image is specified. The result of specifying the image form is input to the storage unit 12 and the image processing unit 15.

  In this case, the storage unit 12 includes a condition 1 storage unit 122 (122a to 122c) that stores a first condition (condition 1) that is an image setting condition prepared in advance for each image form, and a user arbitrarily. Condition 2 storage means 121 (121a to 122c) for storing the second condition (condition 2), which is the set image setting condition, for each image form, and these condition 1 storage means 122a to 122c and condition 2 storage. And condition selection means 123 for selecting image setting conditions stored in the means 121a to 122c.

  The condition selection unit 123 of the storage unit 12 performs image processing on the detection result input from the image detection unit 14, that is, the result of specifying the image form and the value of a write flag described later (that is, the condition 2 storage units 121a to 121c). Based on whether or not the setting condition setting update process has been performed), the conditions for performing the image processing are determined from the image setting conditions stored in the condition 1 storage units 122a to 122c and the condition 2 storage units 121a to 122c. Select and output to the image processing means 15. The image processing unit 15 performs image processing using the image setting condition output from the condition selection unit 123, and the display device 2 performs display by input from the image processing unit 15.

  FIG. 2 is a block diagram showing an example of details of the storage unit 12. The image detection means 14 detects a control signal (vertical / horizontal synchronization signal, clock, etc.) of the input image signal input from the input port 10. The image detection means 14 specifies the image form from these control signals. For example, the number of scanning lines is detected by counting the number of horizontal synchronizing signals between the vertical synchronizing signals, or the number of images included in one scanning line is detected by counting the number of clocks in the horizontal synchronizing signal period, thereby specifying the image form. The detected result is input to an MPU (Micro Processing Unit) 124, a numerical value necessary for image processing is calculated, and output to an LUT (Look Up Table) 125.

  Further, the image form specifying result as the detection result is input to the condition setting means 120. When the image processing setting condition is set by the user by the external input 13 such as a switch, the set image processing setting condition is determined as a condition corresponding to the image form, and the condition 2 storage unit 121 stores the image processing setting condition. The set image processing setting condition is written in the corresponding image form among the three condition 2 storage units 121a to 121c. In this case, the write flag provided for each of the three image forms is set to Low when writing to the condition 2 storage unit 121 is not performed, and is set to High when writing is performed to the condition 2 storage unit 121.

  The condition selection means 123 selects one of the three image forms 1 to 3 from the result detected by the image detection means 14, and stores it in the condition 1 storage means 122 corresponding to the resolution and the number of pixels from the write flag. The selected image processing condition (when the writing flag is Low) or the image processing condition (when the writing flag is High) stored in the condition 2 storage unit 121 is selected. The MPU 124 uses the image processing conditions selected by the condition selection unit 123 to calculate numerical values necessary for image processing and write them to the LUT 125. The image processing means 15 uses the LUT 125 value and the input image data to perform resolution conversion, image display position, image display range, enlargement / reduction, image brightness, contrast, gamma, tone, color temperature, OSD. Perform image processing such as settings.

  FIG. 3 shows a flowchart of the present embodiment. Here, for the sake of simplicity, it is assumed that the input port is not switched, and the processing for one input port will be described. After the image processing apparatus 1 is turned on (step S100), the storage unit 12 performs initialization (step S110). In this initialization, at least processing for setting the write flags of all image forms 1 to 3 to Low is performed. The image selection unit 11 selects an input port based on a signal from the external input 13 such as a switch, and inputs the signal of the selected input port to the image processing unit 15 (step S120). Subsequently, the image detection unit 14 performs input detection (step S120), and detects a valid image input (step S130). When a valid image is input, the image detection unit 14 detects image information and specifies the image form (step S140).

  Subsequently, the condition selection unit 123 selects an image processing condition (step S150). Here, the writing flag is referred to (step S150a). When the write flag corresponding to the specified image form is Low, the condition selection unit 123 reads the image processing condition written in the pre-stored condition 1 storage unit 122 (step S150b), and the write flag is When it is High, the image processing conditions written in the condition 2 storage unit 121 are read (step S150c). Further, the condition selection unit 123 selects three images from the condition 1 storage unit 122 or the condition 2 storage unit 121 selected by the write flag based on the detection result (image form specifying result) of the image detection unit 14. Any one of forms 1 to 3 is selected. Then, the condition selection unit 123 inputs the read image processing condition to the image processing unit 15. The image processing means 15 performs image processing on the image data input from the input port selected using the input image processing conditions (step S160). When the image processing condition setting is updated by the external input 13 such as a switch (step S170), the condition setting unit 120 changes the write flag for the image form corresponding to the detection result of the image detection unit 14 from Low to High. After changing (step S180), the image processing condition is written into the condition 2 storage unit 121 (step S190). The condition selection unit 123 performs image processing of an image form corresponding to the detection result of the image detection unit 14 among the image processing setting conditions stored in the condition 2 storage unit 121 by changing the write flag from Low to High. A setting condition is selected, and the selected image processing condition is input to the image processing means 15 (steps S150a and 150c). The image processing means 15 performs image processing on the image data input from the input port selected using the input image processing conditions (step S160).

  Next, when there are inputs of different image formats in the first input port 100 and the second input port 101, switching of the input port and updating of the image processing conditions will be described using the time chart shown in FIG. . A valid input is always input to the first input port 100. The second input port 101 has no input in the initial state, and valid image data is input from the middle.

  First, the storage unit 12 performs initialization (S200), and the image selection unit 11 selects an input image from the input port selected by the external input 13 such as a switch. In this case, it is assumed that the first input port 100 is selected. At this time, since there is a valid input in the first input port 100, the image detection means 14 detects the image form of the first input port 100 (S210). The image form input to the first input port 100 at this time is referred to as image form 1. The condition selection unit 123 determines the image form detection result and the write flag, and the write flag of the image form 1 input to the first input port 100 is Low, so the condition 1 storage unit for the image form 1 The image processing conditions stored in 122a are selected, and image processing is performed by the image processing means 15 using these conditions (S220).

  Thereafter, when an operation using the external input 13 such as a switch is performed to set an image condition (S230), the condition setting unit 120 writes the image processing condition into the condition 2 storage unit 121a for the image form 1. At this time, the writing flag of the image form 1 changes from Low to High (S240). The change of the write flag of the image form 1 from Low to High indicates that there is a condition written in the condition 2 storage unit 121a of the image form 1. Since the writing flag of the image form 1 has changed from Low to High, the condition selection unit 123 changes the image from the condition 2 storage unit 121a out of the image forms detected by the image detection unit 14 (in this case, the image form 1). Processing conditions are selected and input to the image processing means 15. Thereby, the image processing means 15 performs the image processing of the first input port 100 using the image processing conditions of the image form 1 newly written in the condition 2 storage means 121a (S260).

  It is assumed that after there is a valid input at the second input port 101, switching from the first input port 100 to the second input port 101 is performed by operating the external input 13 such as a switch. Accordingly, the image selection unit 11 switches the input port from the first input port 100 to the second input port 101 (S260). In this case, the form of the image input to the second input port 101 is set to the image form 2. Since the second input port 101 is not set by the user for image processing (writing to the condition 2 storage unit 121b for the image form 2), the write flag for the image form 2 is Low. The image detection means 14 detects the image form of the second input port 101 (S270). The detection signal (in this case, image form 2) is output to the condition selection means 123. The condition selection means 123 determines the image processing conditions written in the condition 1 storage means 122a for the image form 2 based on the write flag (Low in this case) for the image form 2 and the detection signal of the image detection means 14. Select and output to image processing means 15. Accordingly, in this case, the image processing conditions written in the condition 1 storage unit 122a for the image form 2 are used for the image processing (S280).

  Thereafter, it is assumed that switching from the second input port 101 to the first input port 100 is performed by operating the external input 13 such as a switch. Accordingly, the image selection unit 11 switches the input port from the second input port 101 to the first input port 100 (S290). The image detection means 14 detects the image form of the first input port 100 (S300). The detection signal (in this case, the image form 1) is output to the condition selection means 123. The condition selection means 123 determines the image processing conditions written in the condition 2 storage means 121a for the image form 1 based on the write flag for the image form 1 (High in this case) and the detection signal of the image detection means 14. Select and output to image processing means 15. Therefore, in this case, the image processing conditions written in the condition 2 storage means 12a for the image form 1 are used for the image processing (S310). As described above, for the image of the first input port 100, since the writing flag of the image form 1 is High, unless the form of the input image is changed, it is stored in the condition 2 storage unit 121a of the image form 1. The image processing of the input port 1 is performed using the image processing conditions that have been set.

  Next, in this apparatus, when power is turned on for the first time, power is turned on again, and reset operation is performed, image processing is performed by selecting the condition 1 side that is an image setting condition prepared in advance for each image form. Further, when the user sets the image processing conditions, the condition 2 side storage means 121 for the same image form is used as long as the image form does not change no matter how many times the instruction setting from the user is changed. Overwrite the storage area. This is because, in the case of the same image form, it is considered that the image processing condition updated last is most likely to be used unless the power is turned off.

  By using this method, the storage capacity required for one image format is only for writing one kind of image processing condition, and a plurality of image processing conditions associated with frequency, time, program, etc. are retained. Compared to the conventional example, the storage capacity can be greatly reduced.

  As the condition 2 storage means 121 set by the user, DRAM, SRAM, or the like can be used as long as the current storage is maintained. Of course, flash memory and other EEPROM (Electrically Erasable Programmable Read-Only Memory, electrical erasable and write-type storage elements, which retain the stored contents even when the power is cut off), hard disks (even if the power is cut off using magnetic media) It is also possible to use a storage medium (such as holding the storage contents). However, the process of rewriting EEPROM such as flash memory is more complicated than DRAM and SRAM, and the unit price of the device is also expensive. In addition to the price of a single hard disk, it is expensive because peripheral parts are required for control. In the present apparatus, condition 1 is used when the power is shut off or reset. Therefore, there is no problem even if the stored contents for condition 2 are erased by shutting off the power. Accordingly, DRAM and SRAM are preferable from the viewpoint of ease of rewriting process and cost, and SDRAM is particularly preferable because of its low unit cost.

  Next, in the present apparatus, in particular, the resolution conversion of an image enables easy setting by using the display mode, and the display mode will be described below. In the image processing means 15, at least a pixel input as a display mode is directly associated with a pixel of the display device 2, a display without resolution conversion (hereinafter referred to as a through mode), and an entire display portion by the display device 2 by resolution conversion. Display that does not maintain the aspect ratio of the input image (displays the number of pixels in the vertical and horizontal directions to be output by enlarging or reducing the vertical and horizontal directions of the input image. Display that maintains the aspect ratio of the input image, and at least one of horizontal and vertical matches the number of horizontal and vertical pixels output by the image processing means 15 (hereinafter referred to as magnification mode) Select from the following three methods.

  When the aspect ratios of the display device 2 and the input image match, the input image is displayed in the full display area of the display device 2 in both the full screen mode and the scaling mode. On the other hand, when the aspect ratios of the display device 2 and the input image do not match, different display is performed in the scaling mode and the full screen mode as shown in FIG. By selecting these three display modes, even if the input image and the aspect ratio assumed by the image processing means 15 do not match, at least the display mode setting of the image display mode is set to the through mode, the magnification mode, and the full screen mode. By selecting the three modes, it is possible to easily set the resolution. Three switches for directly selecting these modes may be provided. If the switch performs control to sequentially switch the three display modes by pressing one switch, the three display modes can be switched by one switch, and the installation area of the switch can be reduced.

  Thus, according to the first embodiment, when there is an overwrite update to the condition 2 storage unit 121, the condition 2 is selected, and when there is no overwrite update to the condition 2 storage unit 12, Since the image setting condition corresponding to the image form specified by the image detection unit 14 is selected from the condition 1 storage unit 122 and the condition 2 storage unit 121 so that the condition 1 is selected, the user's Since the selection is made when the second condition by the setting is updated, there is an effect that convenience is improved. Furthermore, by default, condition 1 which is an image setting condition prepared for each image form is selected in advance, and the same image processing condition is always set initially, so that the operation for resetting the image processing condition is reset. The amount is reduced and the convenience is improved. In addition, since the setting conditions are overwritten in the condition 2 storage unit 121 for each image form, it is necessary as compared with the conventional example in which a plurality of image processing conditions associated with the frequency, time, program, and the like are held. There is an effect that the storage capacity is small.

  When the correspondence between a plurality of input ports and the image forms input from these input ports is fixed, storage means for condition 1 and condition 2 is provided for each input port, and the input ports are switched and The corresponding image processing condition may be selected based on the presence or absence of the update setting process for the second storage unit. That is, in this case, a plurality of input ports to which image signals are input, a port switching detection unit that detects switching of the plurality of input ports, and a first image setting condition prepared in advance for each input port. First storage means for storing conditions and second conditions that are image setting conditions set by the user are stored for each input port, and the second condition is overwritten and updated when the setting is changed. When there is an overwrite update to the storage means and the second storage means, the second condition is selected, and when there is no overwrite update to the second storage means, the first condition is selected. A condition selection means for selecting an image setting condition corresponding to the input port detected by the port switching detection means from the first and second storage means; and an image setting condition selected by the condition selection means. So that and an image processing means for performing image processing. In this case, if there is an overwrite update to the second storage means, the second condition is selected, and if there is no overwrite update to the second storage means, the first condition is selected. Thus, since the image setting condition corresponding to the input port detected by the port switching detection means is selected from the first and second storage means, the second condition according to the user setting is updated. This makes it possible to improve the convenience. Furthermore, by default, the first condition that is an image setting condition prepared for each input port is selected in advance, and the same image processing condition is always set initially, so the image processing condition is reset. The amount of work to be performed is reduced, and the convenience is improved. In addition, since the setting condition is overwritten in the second storage means, the required storage capacity is small compared to the conventional example in which a plurality of image processing conditions associated with frequency, time, program, and the like are held. Play.

(Second Embodiment)
FIG. 6 is a block diagram showing a second embodiment of the present invention. Description of the same parts as those of the first embodiment is omitted. In this case, the image processing conditions of the condition 1 storage unit 122 can be rewritten. The storage element connection terminal 126 is connected to the external storage element 41 that stores the contents to be written in the condition 1 storage means 122. In the memory element connection terminal 126, a terminal for detecting that the memory element 41 is connected may be set. When the connection of the storage element 41 is detected, the reading control unit 127 performs reading only when the update of the image processing information of the condition 1 storage unit 122 is set by the external input 40 such as a switch in order to prevent malfunction. The information read by the read control unit 127 is input to the write control unit 128, and the image processing conditions in the condition 1 storage unit 122 are updated or newly written.

  In the present embodiment, the image processing conditions written in the preset condition 1 storage unit 122 are used when the power is turned on and restarted, or when reset is performed. The image processing condition written in the condition 1 storage unit 122 is not a condition that is rewritten every time it is used, but is rewritten and added / updated as necessary. Examples of the storage means to be used include an EEPROM such as a flash memory, an EPROM (Erasable Programmable Read-Only Memory), or a hard disk.

  In addition to this, it is also possible to use a ROM (Read-Only Memory) to write and mount necessary information in advance and replace the ROM itself when rewriting, addition or update is necessary. However, in consideration of workability, it is preferable to use the rewritable storage means.

  In the present embodiment, the information to be updated is prepared in a file format. In the file configuration, the corresponding image processing conditions are recorded for each format of the input port. New items are set for the newly standardized format. To set up this file, run the software on the computer, change the settings as necessary, save the changed conditions in a file format, and use them for updating, so you can flexibly deal with each usage environment. It becomes possible. There are no particular restrictions on how the file is updated. A serial port, a parallel port, a USB port, or the like may be provided as an external port, and updating may be performed via this port. Further, by installing a slot for a memory device such as a memory card, the update may be performed via the memory card or the like.

(Third embodiment)
FIG. 7 is a block diagram showing a third embodiment of the present invention. The image processing apparatus 1 is the same as that of the first embodiment or the second embodiment, and for the sake of simplicity, only main blocks are described and surrounded by a dotted line. An input image subjected to image processing by the image processing apparatus 1 is input to the liquid crystal display control means 21 as an image signal and a control signal. The liquid crystal display control means 21 uses these signals to adjust the timing for displaying on the subsequent liquid crystal display 20 and display on the liquid crystal display 20. The liquid crystal display control means 21 uses the buffer 22 to set the arrangement of display data (number of data to be input to the liquid crystal display) and the input method (parallel, serial, etc.) necessary for displaying on the liquid crystal display 20. Then, timing adjustment is performed to absorb the difference in timing between the input to the liquid crystal display control means and the signal required for display by the liquid crystal display.

  The present invention does not limit the display method. For example, in addition to liquid crystal displays, CRT (Cathode Ray Tube), PDP (Plasma Display Panel), EL displays, light modulation elements that modulate transmitted or reflected light according to the input of electrical signals, light sources and projection type A front or rear projector using a combination of an optical system and a screen can be used.

  For the audio signal related to the input image, the image selection unit 11 selects the image and simultaneously selects the audio information if the selected image has audio information. The image processing unit 11 also sets at least one of the volume, sound quality, localization, and number of channels used for the sound. The image setting conditions in the conditions 1 and 2 include settings related to these sounds. As a result, it is possible to simplify the setting for the related sound simultaneously with the setting of the image.
