20150160800
Embodiments described herein relate generally to image adjustment of an image display device.
A conventional image display device, for example, a conventional television receiver, displays on its screen, a setting menu indicating an adjustment item of an image and audio and degrees of an adjustment (an adjustment value) with on-screen display (OSD), and the adjustment value are set by operating buttons provided at a main body or a remote control.
In a conventional image display device, a setting menu is superimposed on an image displayed on a screen. Thus, even if an image is changed by changing adjustment values, the change cannot be easily visibly recognized. Inevitably, setting cannot be easily performed. Furthermore, in order that the values be adjusted, they are each changed by a fixed value at a time by giving an instruction with a button. Thus, it is not easy to greatly or finely change the value.
Furthermore, it is hoped that with respect to each of picked-up images, especially, pictures, adjustment values could be set, and once an actual image (actual picture) is set, it could be repeatedly displayed in the same adjustment state.
Also, it is hoped that once an actual image (actual picture) is finely set in a given image display device (monitor), even if any image display device (monitor) is applied, it could reproduce an image (picture) identical to the actual image (actual picture) at the same adjustment value as in the actual image (actual picture).
A general architecture that implements the various features of the embodiments will now be described with reference to the drawings. The drawings and the associated descriptions are provided to illustrate the embodiments and not to limit the scope of the invention.

A first embodiment will be explained with reference to the accompanying drawings.
It should be noted that a main menu (menu for monitor) to be displayed by the monitor apparatus 10 is a simple setting menu having a small size which is limited regarding display items and adjustment values. The simple setting menu is set as a specific menu for the monitor apparatus 10, which is not displayed in a display module of the personal computer 12. If the personal computer 12 issues a request for transmission of an HTML menu which is a detailed adjustment menu, and the monitor apparatus 10 displays the detailed adjustment menu, the simple setting menu displayed by the monitor apparatus 10 is dismissed when the detailed adjustment menu is displayed. It should be noted that the detailed adjustment menu includes at least a first group of adjustment items and adjustment values, and also a includes second group of adjustment items and adjustment values which are obtained by adding another or other adjustment items and another or other adjustment values to the first group of adjustment items and adjustment values.
The image source device 11 is a device which supplies an image signal to the monitor apparatus 10, and includes a camera device 15, a TV tuner, a DVD (registered trademark)/BD (registered trademark) player 14, a set-top box, etc. The image source device 11 and the monitor apparatus 10 are connected to each other by a cable 16 conforming to image display standards of a display port or a High-Definition Multimedia Interface (HDMI) monitor port. HDMI Standards include, for example, HDMI 1.4 and HDMI 2.0.
The personal computer 12 is connected to the monitor apparatus 10 by a wireless LAN (e.g., IEEE802) using an access point 8 or a cable LAN. To be more specific, the personal computer 12 may be directly connected to a LAN port of the monitor apparatus 10 by a LAN cable (not shown). Alternatively, it may be set that the personal computer 12 is connected to the access point 8 by a wireless LAN 6-1, and the access point 8 is connected to the LAN port of the monitor apparatus 10 by a wireless LAN 6-2 or a LAN cable (not shown). Furthermore, in order to output an image signal to the monitor apparatus 10, the personal computer 12 is connected to a monitor port of the monitor apparatus 10 by a video cable, e.g., an HDMI cable 17.
It should be noted that the monitor apparatus 10 and the image source device 11 do not need to be physically separated from each other; that is, in the first embodiment, a television receiver may be provided as a combination of the monitor apparatus 10 and the image source device 11. The personal computer 12 receives a setting menu image for image adjustment, from the monitor apparatus 10, and causes the setting menu image to be displayed by a web browser.
However, in a TV mode in which a TV signal is input to the monitor apparatus 10, and a TV image is displayed, or a movie mode in which an image such as a movie is displayed, image adjustment cannot be performed after calibration, and an image is displayed in a default image setting determined in a predetermined TV/movie mode.
The OSD signal production module 38 makes a main menu to be displayed on the LCD panel 26 by on-screen display (OSD). An output of the OSD signal production module 38 is supplied to the image processing module 24, and the main menu is superimposed on an image to be adjusted such as a picture. As described above, the main menu can be omitted. If it is omitted, the OSD signal production module 38 can also be omitted. The system controller 28 also controls brightness and color temperature of the backlight 40.
The CPU 50 is a processor which controls operations of various modules provided in the personal computer 12. The CPU 50 executes software loaded from an SSD 58, which is a nonvolatile storage device, into the main memory 54, and as the software, various kinds of software can be applied. The software includes an operating system (OS) 54a, a browser 54d, etc.
The browser 54d causes an HTML menu image to be displayed by the touch screen display 68 based on an HTML file which is sent from the wireless communication device 34 of the monitor apparatus 10, and received by the wireless communication device 64.
The CPU 50 also executes a basic input output system (BIOS) stored in the BIOS ROM 56. The BIOS is a program for controlling hardware.
The system controller 52 is an interface which connects the CPU 50 and various components. The system controller 52 incorporates a memory controller not shown which controls an access to the main memory 54. To the system controller 52, the main memory 54, the BIOS ROM 56, the SSD and/or hard disk drive (HDD) 58, the graphics controller 60, the sound controller 62, the wireless communication device 64, the EC/KBD controller 66, a display interface 70, etc., are connected.
The graphics controller 60 controls an LCD 68a serving as a display monitor of the personal computer 12. The graphics controller 60 transmits a display signal to the LCD 68a under a control by the CPU 50. The LCD 68a displays a screen image based on the display signal. At a display surface of the LCD 68a, a touch panel 68b is provided. It should be noted that the monitor of the personal computer 12 is not limited to the touch screen display 68, and an ordinary monitor formed of LCD 68a may be applied as the monitor of the personal computer 12. In this case, an item in the HTML menu and a value of the item can be selected using a mouse or the like.
The sound controller 62 is a controller which processes an audio signal or an alarm, and produces an audio signal or an alarm to be output from a speaker 42a. The alarm is given, for example, in the case where an operation is not correctly performed.
The cable and wireless communication device 64 is configured to execute communication with another device through a LAN cable, and also wireless communication such as wireless LAN or 3G mobile communication or near field wireless communication such as near field communication (NFC). With the cable and wireless communication device 64, the personal computer 12 is connected to the monitor apparatus 10.
The EC/KBD controller 66 is a one-chip microcomputer in which an embedded controller and a keyboard controller are packed, the embedded controller being provided to perform a power control, the keyboard controller being provided to control a keyboard. The EC/KBD controller 66 also includes a panel controller which controls the touch panel 68b. The EC/KBD controller 66 has a function of powering up and down the personal computer 12 in accordance with an operation of a power supply button not shown.
Next, image adjustment according to an embodiment will be explained.
Of operation buttons of the monitor apparatus 10, if a menu button, a center key of a cruciform button or a center key of a double-button is pressed, while an image to be adjusted is being displayed by the monitor apparatus 10 as shown in
It should be noted that although the main menu is superimposed on the background image, the image is not limited to the above image to be adjusted. The image to be adjusted may be selected afterward. Also, as the background image, an image prepared in advance in a memory in the monitor apparatus 10 may be applied, or an image for adjustment which is supplied from the image source device 11 or the personal computer through cables 16 and 17 for HDMI or the like may be applied.
The main menu includes, for example, the items “Image input”, “Image mode”, “Adjustment mode”, “Color temperature”, “Color temperature”, “Backlight”, “Volume of headphones”, “Software (firmware) update”, “Initialization”, “Format indication of image signal being input”, “Indication of IP address of device”, “Indication of elapsed time from execution of calibration” and “Indication of version of software”. Any of the items is selected with a cursor which is moved by pressing an up or down key. After the cursor reaches the uppermost item, if the up key is further pressed, the cursor is moved to the lowermost item. Similarly, after the cursor reaches the lowermost item, if the down key is further pressed, the cursor is moved to the uppermost item. In such a manner, the up and down keys cause the cursor to be moved in a manner of loop operation.
For example, selection of each of the items is performed as follows. The image input is set to one of “HDMI 1”, “HDMI 2” and “Display port”. The image mode is set to one of “Adobe RGB”, “RGB”, “BT. 709”, “EBU”, “SMPTE-C”, “DICOM-sim”, “Television” and “Movie”. The adjustment mode is set to one of “Preset” and “Custom”. The color temperature is set to fall within the range of 4,000 to 15,000 K while being changed in increments or decrements of 100 K. The backlight is set to fall within the range of 40 to 350 cd/m2 while being changed in increments or decrements of 10 cd/m2 (only in a manual setting).
The volume of the headphones is set to fall within the range of 0 to 100 while being changed in increments or decrement of 5 (it can be adjusted when a headphones terminal is used). “Software (firmware) update” and “Initialization” are each set to one of “Execution” and “Non-execution”. “Format of image signal”, “IP address”, “Elapsed time after execution of calibration” and “Version of software” are automatically displayed. It should be noted that “Calibration” is a color calibration, and is automatically performed when a sensor connected to a USB terminal of the monitor apparatus 10 is brought into intimate contact with the LCD panel 26 to measure brightness and color.
A choice (item value) of each item is selected by pressing a left or right key. Also, the left and right keys, as well as the up and down keys, may be set to cause the cursor to be moved in the manner of loop operation. However, with respect to selection of an item value, there is a case where preferably, the cursor should not be moved in the manner of loop operation. Whether to move the cursor in the manner of loop operation or not is determined arbitrarily.
In such a manner, by operating operation buttons of the monitor apparatus 10, the main menu is superimposed on the image by the OSD, and an item and an item value are selected by operation of operation buttons, thereby selecting an image adjustment value.
Next, it will be explained with reference to a flowchart of
In block B52, in the personal computer 12, a browser is launched, with a background image displayed by the monitor apparatus 10 as shown in
When the IP address of the monitor apparatus 10 is input as a URL, the personal computer 12 establishes a communication channel to the monitor apparatus 10. It is confirmed that the communication channel is established (yes in block B56). Thus, the monitor apparatus 10 is requested to transmit an HTML file of the setting menu image, which is stored in the setting menu storage module 36 (block B58). The monitor apparatus 10 transmits the HTML file and set values of various adjustment items stored in the flash memory 30 to the personal computer 12 (block B82). It should be noted that the set values stored in the flash memory 30 may be reset to initial values at the time of powering down the monitor apparatus 10.
The personal computer 12 displays an HTML menu based on the HTML file and set values received from the monitor apparatus 10 (block B60). In the case of changing a presently displayed background image after the HTML file is displayed, an image to be adjusted is selected as another image (not shown). Also, in the case where the presently displayed background image is not changed, i.e., it is selected, an indication to the effect that the image to be adjusted is the presently displayed background image is selected (block B61). Upon determination of the selected image, an image signal for the selected image is input from a display interface 70 of the personal computer 12 to an input module 10 of the monitor apparatus 10, e.g., an HDMI input module 10, and displayed on the display 68 of the monitor apparatus 10. If the selected image is input, displaying of the main menu is stopped, and only a selection image for image adjustment is displayed on the display 68 of the monitor apparatus 10 (block 83).
An example of the HTML menu is shown in
The following is an explanation of the case where HDMI 2 to which the personal computer 12 is connected is selected in the detailed menu. An HMTL menu includes, for example, the items “Image mode”, “Backlight”, “Color temperature”, “RGB Drive”, “Image detailed adjustment”, “High image quality” and “Resolution plus”.
Choices of the items are, for example, the following. “Image mode” is set to one of “User”, “sRGB”, “BT. 709”, “EBU”, “SMPTE-C”, “DCI”, “DICOM-sim”, “Television” and “Movie”. A choice to be displayed is selected when being tapped or clicked (hereinafter referred to as “tapped”). In such a manner, since an item and an item value can be selected by single tapping, the operability is improved. A button operation which is performed as in that in the main menu needs two selections, i.e., a selection of an item and that of an item value.
In each of the items “Backlight”, “Color temperature”, “RGB Drive” and “Image detailed-adjustment”, a slider is displayed, and a value can be set by moving the slider. It is therefore easy to greatly change the value or finely adjust it. In the case of changing the RGB Drive, the slider is displayed by checking a check box of each of “R”, “G” and “B”; and the brightness of each of R, G and B can be adjusted by moving the slider leftwards or rightwards. “Backlight” is set to fall within the range of 50 to 100 cd/m2, while being changed in increments or decrements of 10 cd/m2. “Color temperature” is set to fall within the range of 4,000 K to 15,000 K, while being changed in increments or decrements of 100 K. “RGB Drive” is set to fall within the range of 0 to 100% with respect to each of R, G and B. It should be noted that “RGB Drive” cannot be set to 30% or less with respect to the total value of “R”, “G” and “B”. Also, “Color temperature” and “RGB Drive” are independent of each other. “Image detailed-adjustment” includes the items “Contrast”, “Black level”, “Gamma”, “Coloring”, “Color strength” and “Sharpness”. “Contrast” is set to fall within the range of 0 to 100 while being changed in increments or decrements of 10; “Black level” is set to fall within the range of −50 (dark) to +50 (light) while being changed in increments or decrements of 10; “Gamma” is set to fall within the range of 1.6 to 2.7 while being changed in increments or decrements of 0.1; and “Coloring”, “Color strength” and “Sharpness” are each set to fall within the range of −50 to +50 while being changed in increments or decrements of 10. “High image quality” and “resolution plus” are each set to “ON” or “OFF”.
In the menu, a field to which a file name is input to save or restore a set file, a save button and a restoration button are displayed. The save and restoration will be described later.
In setting of the above image mode, if “Television” or “Movie” is selected, “Backlight”, “Color temperature”, “RGB Drive”, the items of “Image detailed-adjustment” and “Save/restoration of set file” in the detailed menu are displayed in gray and inhibited from being selected. Furthermore, in the image mode of “Television” or “Movie”, only the items “High image quality”, “Resolution plus” (super high resolution), etc., can be selected. In the image mode of “Television” or “Movie”, in order that a television or movie be viewed as optimal images, an apparatus which supplies the television/movie sets “Backlight”, “Color temperature”, “RGB drive” and “image detailed-adjustment” of the monitor apparatus 10 to optimal values such that the values are inhibited from being changed. Also, in setting of another image mode for an image obtained by a user or the like, the items “High image quality”, “Resolution plus”, etc., are inhibited from being selected.
In block B62, if set values of the items are adjusted, they are transmitted to the monitor apparatus 10.
In the monitor apparatus 10, the system controller 28 stores the adjusted set values in the flash memory 30, and sets them in the image processing module 24 or the backlight 40. Thereby, the monitor apparatus 10 adjusts a display made due to an image signal from the image source device 11. A menu for setting values of adjustment items is displayed by the personal computer 10, not the monitor apparatus 10. Thus, the image displayed by the monitor apparatus 10 is not obstructed by the menu, and it is therefore possible to check in detail how changes of the set values are reflected in the display and to what degree the set values should be changed, and is thus possible to determine accurate set values. Each time setting of the monitor apparatus 10 is changed, set values of the monitor apparatus 10 are transmitted to the personal computer 12 (block B86). In block B88, the monitor apparatus 10 displays an image subjected to adjustment.
The set values transmitted to the personal computer 12 are displayed on the display 68 of the personal computer 12 in block B64; and also if the set values correctly reflect correction, e.g., if they are new in time, it is determined that the set values are changed (block B66). That is, if the time described in attribute information of the set values transmitted to the personal computer 12 is later than the time at which set values adjusted in block B62 were transmitted to the monitor apparatus 10, a set file of the set values transmitted to the personal computer 12 can be saved by inputting its file name in the item “Save and restoration of set file” (block B72). If it is set to save the set file, in block B74, the set file is stored in a memory device such as the SSD 58 or HDD4. In order to change settings with reference to the set items, if it is not set to save the set file, processing to be executed is returned to block B62. Also, if it is necessary to perform a detailed adjustment using a new image after saving the set file, in block B76, it is determined whether a subsequent adjustment image is present or not. In block B76, if it is determined that a new adjustment image is present, the processing is returned to block B61 to select a new image, and the processes of blocks B61 to B70 are executed.
In block B66, if the set values are not correctly received by the personal computer 12, or the set values do not correctly reflect correction, e.g., if the set values are not new in time, it is determined that the set values are not changed. If the set values are not changed, a communication channel is re-established, the processing is returned to block B61, and the processes of blocks B61 to B70 are executed.
Furthermore, in block B76, if a subsequent adjustment image is not present, processing ends in block B78.
In such a manner, the monitor apparatus 10, which has an image adjustment function and actually displays an image, communicates with the personal computer 12, which performs a menu display and an adjustment-value operation, though a network. Thus, if this communication is not correctly performed, the set values of the personal computer 12 are not correctly reflected in the image adjustment by the monitor apparatus. In view of this point, the personal computer 12 determines whether the set values are correctly changed in the monitor apparatus 10 or not. If the set values are not correctly changed, there is a possibility that communication between the monitor apparatus 10 and the personal computer 12 may not be correctly performed. Thus, a communication channel is established in block B70, and the processing is returned to block B58. If the set values are correctly changed, the set values adjusted by the personal computer 12 are reflected in the monitor apparatus 10, and it is therefore determined whether the set file should be saved or not in block B72. If it is determined that the set file should be saved, the set file transferred from the monitor apparatus 10 is saved in block B74; and if it is determined that the set file should not be saved, the processing is returned to block B62.

A set file which is saved in block B74, as shown in
To be more specific, in each of set files, parameter values set in the items of the detailed menu as shown in
Referring to a flowchart shown in
A flow of an interrupt operation and saving of such a detailed set file as shown in
Based on the menu as shown in
If the desired set values are determined, the user of the personal computer 12 inputs a file name of a file to be saved, to a filename input field in the menu (
Next, a flow of restoration of the set file will be explained with reference to
In the case where an image name is specified by referring to the detailed set file as shown in
To be more specific, an image signal is output from the personal computer 12 to one or more monitor apparatuses 10-1 to 10-4 through an allotter 7, and at the same time, the detailed set file is output to one or more monitor apparatuses 10, to thereby enable an image adjusted with the same set parameters to be displayed by one or more monitor apparatuses 10. Therefore, one or more monitor apparatuses 10 can display the adjusted image set by the user in the same state, as a result of which it is possible to save time and trouble which would be required and given if the monitor apparatuses 10 are each adjusted, and also possible to cause an image whose quality is maintained as that of an art work to be displayed on any of the monitor apparatuses 10.
In restoration of an image in the monitor apparatus 10, as shown in
Thereby, image adjustment can be re-achieved in the same adjustment items and adjustment values as in those previously selected and set, without re-selecting adjustment items and re-setting adjustment values.
Furthermore, with file data having a format as shown in
As explained above, according to the first embodiment, an electronic apparatus having a web browser is connected to a monitor apparatus which performs image adjustment, through a network; and a menu image for image adjustment is transmitted from the monitor apparatus to the electronic apparatus, and displayed by the electronic apparatus. The user can select an adjustment item or items on the menu image displayed by the electronic apparatus, and set values of the adjustment items. The set values are transmitted to the monitor apparatus, and image adjustment is performed by the monitor apparatus based on the adjustment values set in the menu image. Therefore, it is possible to solve the following problems of a conventional method in which values of adjustment items are set using buttons of a main body of the monitor apparatus or those of a remote control while viewing a menu displayed by the monitor apparatus with OSD, and also possible to set accurate set values in a short time. In the conventional method, the menu is superimposed on an image, and it is therefore hard to confirm how the image is adjusted; and it is also hard to perform an operation with the buttons. Those problems, as described above, are solved by the first embodiment. In the conventional method, in order to accurately confirm how adjustment is reflected in the image, it is necessary to dismiss the menu each time such a confirmation is made, and the operation is troublesome. In the first embodiment, setting can be performed while viewing an entire image displayed by the monitor apparatus. Accordingly, it is possible to finely confirm how adjustment is reflected in the image. In addition, the WEB browser can be more easily operated than the buttons, thus improving the convenience of the user.
The electronic apparatus has only to include a web browser; that is, it is not necessary to install a specific application on the electronic apparatus. Thus, a notebook or tablet computer owned by the user can be applied; that is, it is not necessary to prepare a specific remote control or apparatus manufactured at a high cost. Furthermore, the electronic apparatus includes a larger display as a remote control, and also input interfaces such as a mouse, a keyboard and a touch panel. Therefore, even if settings are complicated, their contents can be displayed by the electronic apparatus, thus enabling inputting and operation to be easily performed. Although the monitor apparatus and the personal computer need to be connected to each other through LAN, it can be achieved at a low cost to provide a cable or wireless LAN interface at the monitor apparatus.
Moreover, once values are set, they can be saved in a file in the personal computer. Thus, in the case of setting adjustment values for an image identical or similar to a previous one, setting whose values are saved can be easily restored simply by reading the file, and setting of the adjustment values can be performed in a short time. Also, in the case of displaying an image signal identical to a previous one, on the monitor apparatus, it is possible to easily achieve the same setting as in the previous image signal.
It should be noted that since the processing according to the first embodiment can be achieved with a computer program, it is possible to easily obtain the same advantages as in the first embodiment simply by installing a computer-readable storage medium storing the computer program onto a computer.
