Description

  The present invention relates to an image display apparatus having pixels including light emitting elements, and more particularly, an image display apparatus, an image processing apparatus, an image display system, and an image display apparatus control suitable for suppressing uneven display of an image by gradation display. The present invention relates to a program and an image processing apparatus control program.

  2. Description of the Related Art Conventionally, an electro-optical device, for example, a liquid crystal display device using liquid crystal as an electro-optical material has been widely used as a display device in place of a cathode ray tube (CRT) in display units of various information processing devices and liquid crystal televisions. Here, in the conventional electro-optical device, for example, an element substrate provided with pixel electrodes arranged in a matrix, switching elements connected to the pixel electrodes, and a counter electrode facing the pixel electrodes are formed. It is composed of a counter substrate and a liquid crystal which is an electro-optic material filled between the two substrates. In such a configuration, when a certain scanning line is selected, the switching element becomes conductive. In this conductive state, when an image signal having a voltage corresponding to the gradation is applied to the pixel electrode via the data line, a charge corresponding to the voltage of the image signal is applied to the liquid crystal layer between the pixel electrode and the counter electrode. Is accumulated. After the charge accumulation, even if the switching element is turned off, the charge accumulation in the liquid crystal layer is maintained by the capacitance of the liquid crystal layer itself, the storage capacity, and the like. As described above, when each switching element is driven and the charge amount to be accumulated is controlled according to the gradation, the alignment state of the liquid crystal changes for each pixel. For this reason, since the density changes for each pixel, gradation display is possible.

  At this time, the charge may be accumulated in the liquid crystal layer of each pixel for a part of the period. First, each scanning line is sequentially selected, and second, the pixel intersecting with the selected scanning line is selected. The configuration in which an image signal having a voltage corresponding to the gradation of the pixel is applied to the corresponding data line enables time-division multiplex driving in which the scanning line and the data line are shared by a plurality of pixels.

  However, the image signal applied to the data line is a voltage corresponding to the gradation of the pixel, that is, an analog signal. For this reason, a D / A conversion circuit, an operational amplifier, and the like are required for the peripheral circuit of the electro-optical device, which increases the cost of the entire device. Furthermore, display unevenness occurs due to the non-uniformity of these D / A conversion circuits and operational amplifiers and various wiring resistances, so that high-quality display becomes extremely difficult and particularly high definition. There is a problem that it becomes conspicuous when displaying. There is also a problem such as an increase in power consumption due to a D / A conversion circuit, an operational amplifier, or the like.

  Therefore, a method has been developed in which gradation is obtained by controlling the light emission time of the electro-optic element. In this method, it is sufficient to supply a binary signal (digital signal) indicating whether or not the electro-optic element emits light to the data line, and there is an advantage that the above-described analog circuit that adversely affects image quality is unnecessary. However, a problem has arisen that it takes too long to select a scanning line in performing this control.

Therefore, a non-sequential scanning method has been developed as a driving method of a liquid crystal display using a digital signal for solving the above problem. This is the ratio of 2 ⁿ values (n = 0, 1, 2,... (N−1)) of several bits of the bit string constituting the gradation data of bit length N indicating the light emission gradation of the optical element. This is a method of obtaining gradation by controlling the light emission time of this optical element by selecting scanning lines non-sequentially using a numerical group corresponding to the above (see, for example, Patent Document 1).
JP 2001-166730 A.

However, although the principle of the non-sequential scanning method is theoretically described, a specific method for actually realizing it is not clarified.
In addition, the scanning line selection order is determined based on data in a predetermined order in a memory or the like of a control unit that controls each driving circuit of the electro-optical device according to the number of scanning lines and the number of gradations to be controlled in advance. Although stored and controlled, an appropriate method for determining the selection order in the non-sequential scanning method is not clarified.

  Therefore, the present invention has been made paying attention to such an unsolved problem of the conventional technique, and is suitable for displaying an image using a scanning line selection process by a non-sequential scanning method. An object is to provide an image display device, an image processing device, an image display system, an image display device control program, and an image processing device control program.

[Invention 1] In order to achieve the above object, an image display apparatus of Invention 1 includes a pixel matrix in which pixels including optical elements are arranged in a matrix,

A bit length N of gradation data indicating the light emission gradation of the optical element corresponding to the image data acquired by the image data acquisition means and an addition number obtained by adding 1 to the total number of the scanning lines are expressed as the gradation data. While obtaining a numerical value group divided into numerical values according to a ratio consisting of 2 ⁿ values (n = 0, 1, 2,..., (N−1)) of several bits of the bit string constituting
A serial number is associated with each scanning line in the order of arrangement, and a predetermined number among the serial numbers associated with the scanning line is assigned to the least significant bit (0th digit) of the bit string constituting the gradation data. The initial value corresponding to the least significant bit is added to the initial value corresponding to the least significant bit and the largest numerical value included in the numerical value group is added to the most significant bit ((N -1) The initial value of the scanning line corresponding to the digit)), and the other bits between the most significant bit and the least significant bit are ordered in descending order of the number of bit digits of the other bits. A value obtained by adding 1 to the number of bit digits of the other bits from the smallest of the initial value corresponding to the bit one digit higher than the number of bit digits of the other bits and the numerical value included in the numerical value group Number And initial value setting means for setting an initial value of the other bits a value obtained by adding the,

  With this configuration, the scanning line selection order determination unit generates a random number when determining the selection order of the scanning line with the serial number indicated by the initial value, and selects the selection order based on the generated random number. Since it can be determined as the initial scan line selection order, the scan line selection order should be irregular for each bit, not regular order such as ascending or descending order for each bit. Is possible.

Therefore, since it is possible to select scanning lines in an irregular order and display an image, it is possible to obtain an effect that display unevenness in high-definition image display can be suppressed.
Here, when the numerical value group is generated as described above, when the total number of scanning lines +1 cannot be divided at an accurate ratio (divided by an integer corresponding to the ratio), the decimal point in the portion that cannot be accurately divided is calculated. By rounding, rounding off, or selecting nearby values, it is possible to divide the values into neighboring values corresponding to the respective ratios. For example, when the total number of scanning lines is 240 and the bit length of gradation data is 6 bits, the division is performed at a ratio of 1: 2: 4: 8: 16: 32. In this case, Since there is a portion that cannot be divided accurately, a portion that cannot be divided into numerical values with an accurate ratio, such as 4, 7, 15, 30, 62, and 123, is set as its neighborhood value.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 7 are diagrams showing an embodiment of an image display device, an image processing device, an image display device control program, and an image processing device control program according to the present invention.
First, the configuration of the image display apparatus according to the present invention will be described with reference to FIGS. FIG. 1 is a block diagram showing a configuration of an image display device 10 according to the present invention, and FIG. 2 is a diagram showing a configuration of a pixel circuit constituting a panel 10a of the image display device 10.

The image display device 10 includes a panel 10a, a control unit 10b, a drive unit 10c, a frame memory 10d, an image analysis unit 10e, and an image conversion unit 10f.
The panel 10a is configured by arranging pixel circuits including light emitting elements in a matrix, and causes the light emitting elements selected by voltage supply (or current supply) from the driving unit 10c to emit light for a predetermined time. As shown in FIG. 2, the pixel circuit 3 includes a scanning line 30, a data line 31, a current supply line 32, a switching transistor 33, a driving transistor 34, an optical element 35, and a storage capacitor 36. It is a configuration that includes. Here, the operation of the pixel circuit 3 in the present embodiment is controlled in response to the bright signal supplied from the control unit 10b via the drive unit 10c being written as high or low, and the scanning line 30 Regardless of whether or not is driven, the optical element 35 emits light when the bright signal is written as high through the data line 31, and does not emit light when it is written as low. In the present embodiment, the optical element 35 is an electroluminescence element. Further, the image display device 10 according to the present embodiment uses binary bit data as a signal (bright signal) to be applied to the data line 31, and uses this bit data for an optical element in a period of one frame. The light emission time of 35 is controlled. Thus, gradation display is performed by controlling the light emission time of the optical element 35 according to the time corresponding to each bit of the bit string constituting the gradation data.

  The control unit 10b controls the driving unit 10c according to the basic vertical scanning signal, horizontal scanning signal, dot clock signal, and gradation data. That is, the drive unit 10c is caused to select the scanning lines in the image display area in the panel 10a in a specific order by non-sequential scanning based on the image data for non-sequential scanning, and the voltage is applied to the pixels of the selected scanning line. (Or supply current).

The drive unit 10c is controlled by the control unit 10b, and selects the scanning lines in the image display area in the panel 10a in a specific order by non-sequential scanning, and the scanning line selected based on the image data to be displayed. A voltage is applied (or current is supplied) to the pixel.
The frame memory 10d is a memory for handling an image to be displayed in the image display area, takes out image data corresponding to non-sequential scanning on this memory, and drives the pixels of the corresponding scanning line of the panel 10a.

The image analysis unit 10e analyzes image data acquired from an external device and transmits the analysis result to the image conversion unit 10f. The analysis content here includes the number of colors and resolution of the image data.
The image conversion unit 10f converts the acquired image data into non-sequential scanning image data based on the analysis result from the image analysis unit 10e and the number of scanning lines on the display panel. The converted image data is stored in the frame memory 10d. In this embodiment, the selection order of scanning lines is determined using random numbers, and conversion processing for rearranging the pixels constituting the image data based on the determined selection order is performed, thereby performing non-sequential scanning. Generate image data.

  Here, in the present embodiment, although not shown, the image display device 10 is a storage medium storing a program for controlling the above-described units, a CPU for executing these programs, and executing the programs. And a RAM for storing necessary data. And the process of each said part is implement | achieved by running the said program by said CPU.

  The storage medium is a semiconductor storage medium such as RAM or ROM, a magnetic storage type storage medium such as FD or HD, an optical reading type storage medium such as CD, CDV, LD, or DVD, or a magnetic storage type such as MO. The optical reading type storage medium includes any storage medium as long as it is a computer-readable storage medium regardless of electronic, magnetic, optical, or other reading methods.

Further, a more specific operation of the image display device 10 will be described based on FIGS. 1 and 3. Here, FIG. 3 shows scanning corresponding to each bit of the gradation data in the selection order of the scanning lines determined by random numbers when the vertical direction is the serial number (0 to 13) of the scanning line and the horizontal direction is time. It is the figure which showed a mode that a line was selected.
First, image data such as a moving image is transmitted from an external device such as a PC (Personal Computer) to the image analysis unit 10e. Thus, the image analysis unit 10e performs image data analysis processing. As described above, the analysis processing examines the number of colors and resolution of the input image. Thus, when information such as the resolution of the image is known, the image conversion unit 10f inputs the input image data based on this information and information such as the total number of scanning lines of the panel 10a and the number of controllable light emission gradations. Is converted into image data for non-sequential scanning. The image data conversion process will be specifically described below.

Here, for convenience of explanation, a case where the total number of scanning lines is 14 and the bit length of gradation data is 4 bits will be described as an example.
First, 15 obtained by adding 1 to the total number 14 of scanning lines is set to 2 ⁿ values (n = 0, 1, 2,..., (N−) of the number of bits of the bit string constituting the gradation data of bit length N. A numerical value group divided according to the ratio of 1)) is generated. That is, since the bit length N of the gradation data is 4 bits, a value 15 obtained by adding 1 to the total number of scanning lines at a ratio of 2 ⁰ : 2 ¹ : 2 ² : 2 ³ = 1: 2: 4: 8. To divide. In this case, it can be divided into 1: 2: 4: 8. Therefore, it is divided into four numerical values 1, 2, 4, and 8 according to the respective ratios.

  Next, serial numbers 0 to 13 are associated with each of the total 14 scanning lines. Then, the serial number 0 of the first selected scanning line (hereinafter referred to as the initial scanning line) is set as an initial value in the LSB (0th bit) of the gradation data. Next, for the third bit (MSB) of the gradation data, the largest 8 among the divided values is added to the serial number 0 of the scanning line selected immediately before, and this serial number 8 is added to the initial scanning line. Set as serial number. Further, the second largest 4 among the divided values is added to the serial number 8 of the scanning line previously selected for the second bit of the gradation data, and this 12 is used as the serial number of the initial scanning line. Set. Furthermore, the third largest 2 among the divided numbers is added to the serial number 12 selected immediately before the first bit of the gradation data. In this case, the numerical value after the addition is the serial number. Since 13 is exceeded, the remainder (0) when the addition result 14 is divided by the total number of scanning lines 14 is set as the serial number of the initial scanning line. In addition, in the case of 15 with 12 added to 3, 15/14 = 1 (remainder 1), the serial number of the initial scanning line in this case is 1.

Therefore, serial number 0 is set as an initial value for LSB, serial number 8 is set as an initial value for MSB, and serial number 12 is set for the second bit in the bit length of 4 bits of gradation data. As an initial value, serial number 0 is set as the initial value for the first bit.
In this way, according to the bit length of the gradation data, as described above, the numerical value obtained by sequentially adding the divided numerical values to the serial number of the scanning line selected immediately before, from the largest to the smallest, The serial number of the initial scanning line corresponding to each bit of the gradation data is determined.

  Further, a random number is generated, and the selection order of the initial scanning lines determined as described above is determined based on the random number. For example, a numerical value of 0 to 3 is associated with each bit of the gradation data. Here, “0” is associated with bit 0 (LSB), “1” is associated with bit 1, “2” is associated with bit 2, and “3” is associated with bit 3 (MSB). Then, it is assumed that random numbers 0 to 3 are calculated using a known random number calculation method, and numerical values 0 to 3 are calculated in the order of “3 → 0 → 2 → 1”. In the present embodiment, the selection order of initial scanning lines is determined using this calculation order as it is. That is, the selection order is as follows: the initial scan line of serial number 8 corresponding to the MSB → the initial scan line of serial number 0 corresponding to the LSB → the initial scan line of serial number 12 corresponding to bit 2 → the initial scan of serial number 0 corresponding to bit 1. Determine the order of the lines.

  Thereafter, 1 is added to the serial number of the initial scanning line corresponding to each bit, and the selection order is determined for the scanning line of the serial number of the addition result using the calculation result of the random number as described above. . At this time, when the result of adding 1 to the initial value corresponding to each bit exceeds the value obtained by subtracting 1 from the total number of scanning lines (here, 13), the addition result is set to 0. That is, when the thirteenth scanning line is selected and 1 is added to the serial number 13, the addition result is not set to a numerical value (14) exceeding the serial number 13 of the scanning line, and 0, which is the minimum value of the serial number of the scanning line. And From the random number calculation result, the selection order of the scanning lines corresponding to each bit of the gradation data is determined by the order of MSB → LSB → second bit → first bit. Accordingly, when the selection order is determined in the order of the 8th scanning line, the 0th scanning line, the 12th scanning line, and the 0th scanning line corresponding to each bit of the gradation data, 1 is assigned to the serial number of the previous scanning line corresponding to each bit, such as the order of selecting the ninth scanning line, the first scanning line, the thirteenth scanning line, and the first scanning line. The selection order is determined so as to sequentially select the scanning lines having the added serial numbers.

As described above, when the scanning line selection order is determined, the image data is converted by rearranging the pixels constituting the acquired image data in the arrangement order corresponding to the selection order based on the determined selection order. Then, image data for non-sequential scanning is generated.
Depending on the total number of scanning lines, the addition number obtained by adding 1 to the total number of scanning lines is the 2 ⁿ values (n = 0, 1, 2,...) Of the number of bits of the bit string constituting the N-bit gradation data. , (N-1)) may not be accurately divided. For example, consider a case where the total number of scanning lines is 240 and the bit length of gradation data is 6 bits. In this case, the addition number 241 obtained by adding 1 to the number of scanning lines is divided at a ratio of 1: 2: 4: 8: 16: 32. However, 241 cannot be accurately divided into this ratio. Therefore, when it is not possible to divide into numerical values with an accurate ratio, such as 4, 7, 15, 30, 62, 123, a numerical value group is generated by setting the value as a neighborhood value thereof.

The generated image data for non-sequential scanning is stored in the frame memory 10d. Then, the image of the non-sequential scanning image data stored in the frame memory 10d is selected by the control unit 10b and the driving unit 10c in the selection order corresponding to the image data as shown in FIG. As a result, the image is displayed in the display area of the panel 10a.
Further, the flow of operation processing of the image display apparatus 10 will be described with reference to FIG. FIG. 4 is a flowchart showing an operation process of the image display apparatus 10.

As shown in FIG. 4, first, the process proceeds to step S100, where the image analysis unit 10e determines whether image data has been acquired. If it is determined that the image data has been acquired (Yes), the process proceeds to step S102, and so on. If not (No), wait until acquisition.
When the process proceeds to step S102, the image analysis unit 10e performs an analysis process on the acquired image data, and the process proceeds to step S104. Here, as described above, the number of colors and resolution of the image are analyzed and examined.

In step S104, the image analysis unit 10e transmits the analysis result to the image conversion unit 10f, and the process proceeds to step S106.
In step S106, the image conversion unit 10f determines the selection order of scanning lines using random numbers, and the pixel data of the image data acquired in step S100 in the arrangement order according to the selection order based on the determined selection order. The image data for non-sequential scanning is generated by rearranging, and the process proceeds to step S108.

In step S108, the image conversion unit 10f stores the converted image data in the frame memory 10d, and proceeds to step S110.
In step S110, the control unit 10b and the drive unit 10c perform a process of displaying the image data stored in the frame memory 10d by scanning non-sequentially in the selection order corresponding to the image data, and the process proceeds to step S100. Here, the frame memory has two areas of a predetermined capacity, and these two areas are switched to display an image. That is, while the converted image is stored in one area, the image stored in the other area is displayed.

Furthermore, the flow of processing for determining the selection order of scanning lines in the image conversion unit 10f will be described with reference to FIG. FIG. 5 is a flowchart showing a process for determining the scanning line selection order in the image conversion unit 10f.
As shown in FIG. 5, first, the process proceeds to step S200, the total number of scanning lines in the display area and the number of light emission gradations of the display image are set, and the process proceeds to step S202.

  In step S202, gradation data having a bit length N corresponding to the set number of gradations is generated, and the process proceeds to step S204. Here, if the number of gradations is determined from the beginning, this process need not be performed if gradation data is generated in advance. The gradation data is a variable having a bit length corresponding to the number of input gradations, for example, a variable having a bit length of 4 bits for 16 gradations and a 6-bit bit for 64 gradations. The variable has a length. In the present embodiment, there are 256 gradations of 8 bits.

In step S204, the sum obtained by adding 1 to the total number of scanning lines is the 2 ⁿ values (n = 0, 1, 2,..., (N−1)) of the number of bits of the gradation data having the bit length N. A numerical value group divided into numerical values corresponding to each ratio of the ratio group consisting of is generated, and the process proceeds to step S206.
In step S206, the number of the initial scanning line corresponding to each bit of the gradation data is calculated and set based on the generated numerical value group, and the process proceeds to step S208.

In step S208, the order of selecting the initial scanning line is determined by random number calculation, and the process proceeds to step S210.
In step S210, an initial scanning line is selected and the process proceeds to step S212.
In step S212, 1 is added to each of the initial scanning line numbers selected in step S210, and the process proceeds to step S214.

In step S214, it is determined whether there is an addition result of the number corresponding to each bit that exceeds the total number of scanning lines. If it is determined that there is an excess (Yes), the process proceeds to step S216. If not (No), the process proceeds to step S222.
When the process proceeds to step S216, the number of the addition result is updated to “0”, and the process proceeds to step S218. In other words, the serial number associated with the scanning line is updated to the minimum value (“0” in this embodiment).

In step S218, the scanning line with the number of the addition result corresponding to each bit is selected, and the selection order of the selected scanning line is determined using the same calculation result as in step S208, and the process proceeds to step S220.
In step S220, 1 is added to the number of the scanning line selected immediately before (the number selected in step S218), and the process proceeds to step S214.

On the other hand, if there is no addition result exceeding the total number of scanning lines and the process proceeds to step S222, the addition result is set as it is, and the process proceeds to step S218.
In the image conversion unit 10f of the image display device 10, the selection order of scanning lines using random number calculation is determined for all using the random number calculation order once calculated. Not limited to this, every time 1 is added to the serial number and the serial number of the scanning line to be selected next is determined, random number calculation is performed, and the selection order of the scanning lines may be determined using the calculation order.

  In the present embodiment, the timing of random number calculation is not particularly defined in the image conversion unit 10f of the image display device 10, but the random number calculation is performed in a predetermined frame (for example, one frame) when displaying an image. It can be done every time. As a result, for example, when one high-definition image is continuously displayed, a plurality of types of scanning line selection orders can be set, and the selection order of scanning lines can be made more irregular as viewed from the entire display time. It becomes.

As described above, in the image conversion unit 10f, as described above, the selection order of scanning lines in non-sequential scanning is determined using a random number, and based on the determined selection order, the image data is sorted in the arrangement order corresponding to the selection order. Image data for non-sequential scanning can be generated by rearranging the pixel data.
Further, the configuration of the image display system according to the present invention will be described with reference to FIG. FIG. 6 is a block diagram showing the configuration of the image display system 2 according to the present invention.

As shown in FIG. 6, the image display system 2 includes an image display device 20 and an image processing device 21.
The image display device 20 includes a panel 10a, a control unit 20a, a drive unit 10c, and a frame memory 20b.
Here, the panel 10a and the drive unit 10c are the same as those shown in FIG.

The control unit 20a controls the drive unit 10c based on the scanning line selection order information and the non-sequential scanning image data stored in the predetermined area of the frame memory 20b to display the non-sequential scanning image data image. Do.
The frame memory 20b stores the image data for non-sequential scanning and the selection order information of the scanning lines corresponding to the image data from the image processing device 21 in respective predetermined areas on the memory.
The image processing device 21 includes an image analysis unit 21a, a device information acquisition unit 21b, and an image conversion unit 21c.

The image analysis unit 21a analyzes image data acquired from an external device and transmits the analysis result to the image conversion unit 21c. The analysis content here includes the number of colors and resolution of the image data.
The device information acquisition unit 21b acquires information of the image display device 20 such as information on the number of light emission gradations of the light emitting elements in addition to the number of scanning lines and the number of data lines of the display area in the panel 10a. It is transmitted to the image conversion unit 21c.

The image conversion unit 21c converts the acquired image data into non-sequential scanning image data based on the analysis result from the image analysis unit 21a and the acquisition result of the apparatus information acquisition unit 21b. Then, the selected scanning line selection order and non-sequential scanning image data are transmitted to the image display device 20.
Here, in the present embodiment, although not shown, the image processing apparatus 21 stores a storage medium storing a program for controlling the above-described units, a CPU for executing these programs, and executing the programs. And a RAM for storing necessary data. And the process of each said part is implement | achieved by running the said program by said CPU.

  The storage medium is a semiconductor storage medium such as RAM or ROM, a magnetic storage type storage medium such as FD or HD, an optical reading type storage medium such as CD, CDV, LD, or DVD, or a magnetic storage type such as MO. The optical reading type storage medium includes any storage medium as long as it is a computer-readable storage medium regardless of electronic, magnetic, optical, or other reading methods.

Furthermore, a more specific operation of the image display system 2 will be described.
First, image data is transmitted from an external device such as a PC to the image analysis unit 21 a of the image processing device 21. As a result, the image analysis unit 21a performs image data analysis processing. As described above, the analysis processing examines the number of colors and resolution of the input image. In this embodiment, the number of bits of gradation data of the input image is 7 bits, and the total number of scanning lines of the image display device 20 is 127.

On the other hand, the device information acquisition unit 21b acquires information on the image display device 20 such as information on the number of light emission gradations of the light emitting elements, in addition to the number of scanning lines and the number of data lines in the display area of the panel 10a, and obtains the acquisition result. The image is transmitted to the image conversion unit 21c.
When the analysis result of the image analysis unit 21a and the acquisition result of the device information acquisition unit 21b are acquired, the image conversion unit 21c performs a process of converting the input image data into image data for non-sequential scanning. Here, the generation processing of the image data for non-sequential scanning in the image conversion unit 21c is the same as the processing of the image conversion unit 10f in the image display device 10, and thus description thereof is omitted.

When the image conversion unit 21c generates non-sequential scanning image data, the image conversion unit 21c transmits the generated image data and scanning line selection order information corresponding thereto to the image display device 20. The image display device 20 stores the image data for nonsequential scanning acquired from the image processing device 21 and the selection order of the scanning lines corresponding thereto in a predetermined area of the frame memory 20b.
In the image display device 20, the control unit 20a removes the scanning lines from the driving unit 10c according to the selection order of the scanning lines based on the non-sequential scanning image data and the scanning line selection information stored in the frame memory 20b. By sequentially selecting and applying a voltage (or current) to a pixel corresponding to the selected scanning line, an image display process of image data is performed. That is, the image display system 2 is configured such that the image analysis unit 10e, the image conversion unit 10f, and the selection order storage unit 10g in the image display device 10 are provided outside as the image processing device 21. However, unlike the image display device 10, it is necessary to acquire information such as the total number of scanning lines and the number of light emission gradations from the image display device 20, and therefore it is necessary to add a device information acquisition unit 21b for acquiring these information. is there.
In the image display system 2, since the total number of scanning lines is 127, 128 obtained by adding 1 to this number is 2 ⁿ values (n of the number of bits of a bit string constituting 7-bit gradation data). = 0, 1, 2, ... (7-1)). That is, 128 is divided into numerical groups according to the ratio of 1: 2: 4: 8: 16: 32: 64, and the numerical values corresponding to each bit are 1, 2, 4, 8, 16, There are seven of 32 and 64.

Further, the flow of operation processing of the image processing apparatus 21 will be described with reference to FIG. FIG. 7 is a flowchart showing the operation process of the image processing apparatus 21.
As shown in FIG. 7, first, the process proceeds to step S300, and the image analysis unit 21a determines whether or not image data has been acquired. If it is determined that the image data has been acquired (Yes), the process proceeds to step S302. If not (No), wait until acquisition.

When the process proceeds to step S302, the image analysis unit 21a performs an analysis process on the acquired image data, and the process proceeds to step S304. Here, as described above, the number of colors of the image and the image size are analyzed and examined.
In step S304, the image analysis unit 21a transmits the analysis result to the image conversion unit 21c, and the process proceeds to step S306.

In step S306, the apparatus information acquisition unit 21b detects the number of scanning lines (in this case, the number of data lines) of the display area in the panel 10a, and the process proceeds to step S308.
In step S308, the device information acquisition unit 21b transmits the detection result to the image conversion unit 21c, and the process proceeds to step S310.
In step S310, the image conversion unit 21c determines the scanning line selection order using random numbers, and the pixel data of the image data acquired in step S300 in the arrangement order corresponding to the selection order based on the determined selection order. The image data for non-sequential scanning is generated by rearranging, and the process proceeds to step S312.

In step S312, the image conversion unit 21c transmits the image data generated in step S310 and the scanning line selection order information corresponding thereto to the frame memory 20b, and the process proceeds to step S300.
In the image conversion unit 21c of the image processing apparatus 21, the selection order of scanning lines using random number calculation is determined for all using the random number calculation order calculated once. Not limited to this, every time 1 is added to the serial number and the serial number of the scanning line to be selected next is determined, random number calculation is performed, and the selection order of the scanning lines may be determined using the calculation order.

  In the present embodiment, the timing of random number calculation is not particularly defined in the image conversion unit 10f of the image display device 10, but the random number calculation is performed in a predetermined frame (for example, one frame) when displaying an image. It can be done every time. As a result, for example, when one high-definition image is continuously displayed, a plurality of types of scanning line selection orders can be set, and the selection order of scanning lines can be made more irregular as viewed from the entire display time. It becomes.
