According to the present invention , an evaluation value of a work environment (for example, an indoor temperature, humidity, brightness, and the like described later) is displayed on a screen that a worker who performs work using an information processing system is watching. The image reflecting the comfort level obtained from these ideal values is displayed . Therefore, the following effects can be obtained.
(1) Even if the worker is enthusiastic about the work, for example, it is possible to easily make the worker aware of the deterioration of the working environment due to the end of the working hours and the air conditioning being turned off.
(2) Since work environment deterioration is reported on the screen that the operator is gazing at, the work being performed using the information processing system is different from the method of acoustically reporting by voice or bell sound. It is possible to notify only the person.
(3) By setting a judgment threshold value for the evaluation value of the work environment for each worker, it is possible to control notification according to the difference in how the worker feels about the work environment, the type of work engaged, and the like.
(4) It has the following advantages compared with the method of acoustically informing the deterioration of the working environment. In the method of notifying with an alarm sound or the like, an alarm sound can be heard by a person other than the worker who is working using the information processing system, which is generally not preferable for an office environment. In particular, as in the ninth aspect of the invention, it is extremely undesirable to adjust the timing at which the notification sound is generated for each worker because the notification sound is generated many times. According to the present invention , such inconvenience can be avoided. In addition, workers who are enthusiastic about the work often miss the alarm sound, but since the notification on the screen according to the present invention is continuous, the deterioration of the work environment is surely ensured. The worker can be made aware.

  In Embodiment 1 of the present invention to be described later, JPEG 2000 still image code data or Motion-JPEG 2000 moving image code data is used as image code data. Motion-JPEG2000 moving image code data is obtained by encoding each frame individually using JPEG2000, with continuous still images as frames. In order to facilitate understanding of the following description, an outline of JPEG2000 will be described here.

  JPEG2000 encoding processing is generally performed according to the flow shown in FIG. The image is divided into rectangular tiles (number of divisions ≧ 1). First, each tile is color-converted into components such as luminance and color difference. At this time, in the case of RGB image data or the like, a DC level shift that reduces half of the dynamic range is also performed.

  The converted component (called a tile component) is divided into four subbands abbreviated as LL, HL, LH, and HH by two-dimensional wavelet transformation. When the wavelet transform (decomposition) is recursively repeated for the LL subband, one LL subband and a plurality of HL, LH, and HH subbands are finally generated.

  FIG. 2 shows subband division by three two-dimensional wavelet transforms. In FIG. 2, n in nLL, nHL, nLH, and nHH means that the subband coefficient is obtained by the n-th decomposition. This n is called a decomposition level. Each subband is also labeled with a resolution level.

  Next, each subband is divided into rectangles called precincts (see FIG. 3). The precinct is a subband divided into rectangles, and precincts corresponding to each of the HL, LH, and HH subbands (a total of three) are treated as a group. However, each precinct obtained by dividing the LL subband is treated as a precinct independently. The precinct roughly represents a position in the image. The precinct can be the same size as the subband. A code block is obtained by further dividing the precinct into rectangles (see FIG. 3). Therefore, the physical size order is image ≧ tile> subband ≧ precinct ≧ code block.

  After the above division, the entropy coding is performed on the subband coefficients (in the case of using an irreversible wavelet transform called 9 × 7 transform, after linear quantization for each subband) in order of bit plane in code block units ( Bit plane encoding) is performed.

  Headers are collected and collected from all code blocks included in the precinct (for example, from the MSB of all code blocks to the third bit plane code) The attached one is called a packet. Since the “part” may be “empty”, the content of the packet may be empty in terms of code. The packet header includes information about codes included in the packet, and each packet can be handled independently. In other words, a packet is a unit of code.

  By collecting packets of all precincts (= all code blocks = all subbands), a part of the code of the entire image (for example, the code of the bit plane from the MSB to the third bit of the wavelet coefficients of the entire image) can be created. But this is called a layer. Since the layer is roughly a part of the code of the bit plane of the entire image, the image quality increases as the number of layers to be decoded increases. That is. A layer is a unit of image quality formed in the bit depth direction. If all the layers are collected, it becomes the sign of all the bit planes throughout the image.

  The upper part of FIG. 4 shows layers when the number of decomposition levels = 2 and the precinct size = subband size, and the lower part shows examples of packets included in the layers surrounded by bold lines. Since the packet is based on a precinct, when precinct size = subband size, the packet spans HL to HH subbands. It is not necessary to generate unnecessary codes as packets. For example, the codes of the lower bit planes included in the layer 9 shown in the upper part of FIG. 4 are usually discarded.

Finally, one code stream (code data) is formed by arranging packets in a predetermined order (progression order) and adding a header or the like. Which component (symbol C) the packet belongs to,
-Which resolution level (symbol R) belongs to
Which precinct ("location") (symbol P) belongs to
-It has four attributes, which layer (symbol L) belongs to. The packet arrangement means the order in which packets are arranged hierarchically. This arrangement order is called a progression order, and JPEG2000 defines five progression orders.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that, in a plurality of block diagrams referred to in the following description, the same or corresponding means will be described with the same reference numbers in order to reduce duplication of description.

[Embodiment 1]
FIG. 5 is a block diagram showing the overall configuration of the system according to the first embodiment of the present invention. The information processing system shown here includes business processing means 100, display data storage means 102, display control means 103, and display means 104. The business processing means 100 is a means for an operator to perform business processing such as document creation, spreadsheet, programming, and the like. Specifically, the business processing means 100 is an application program or the like that runs on a computer. The display data (1) generated by the business processing unit 100 in relation to the business processing is written in the display data storage unit 102 and displayed on the display unit 104 under the control of the display control unit 103. Although not shown in FIG. 5, a GUI (graphical user interface) linked to the screen of the display unit 104 is usually provided, and an operator performs an input operation through this GUI to perform a job.

  The information processing system includes a decoding unit 101. The decoding means 101 is means for decoding still image code data (JPEG2000 still image code data in the present embodiment) or moving image code data (Motion-JPEG2000 moving image code data in the present embodiment). The image data decoded by the decoding unit 101 is also written as display data (2) in the display data storage unit 102 and displayed on the display unit 104 by the display control unit 103.

  Display data (1) and display data (2) are displayed in different display areas (windows) on the screen, or display data (1) is used as display data (2). Can be displayed on the screen as a background (this is the same as in Embodiment 2 below).

  The information processing system includes environment information detection means 110 and environment evaluation means 111. The environment information detection means 110 is a means for detecting work environment information of a worker who performs work using the work processing means 100, and detects work environment information such as a worker's office room and the floor in which the room is located. It is placed in a suitable place. The environment evaluation unit 111 is a unit that evaluates the work environment from the environment information detected by the environment information detection unit 110.

  FIG. 7 is a block diagram showing an embodiment of the environment information detection means 110 and the environment evaluation means 111. In the example shown here, the environment information detection unit 110 includes a temperature detection unit 201 (temperature sensor) that detects room temperature, a humidity detection unit 202 (humidity sensor) that detects indoor humidity, and brightness detection that detects indoor brightness. It is comprised from the part 203 (brightness sensor).

The environment evaluation means 111 is a difference between the indoor temperature t, humidity h, and brightness L detected by each of the detection units 201, 202, and 203 and a preset ideal temperature t0, humidity h0, and brightness L0. Detection units 204, 205, and 206 for obtaining absolute values | t-t0 |, | h-h0 |, | L-L0 |, and absolute values | t-t0 |, | h-h0 |, | L -L0 | is normalized by multiplying by α, β, and γ, respectively, and normalization units 207, 208, and 209, and comfort k from the absolute value of the difference after normalization
k = 1 / (α | t-t0 | + β | h-h0 | + γ | L-L0 |)
And the comfort level k is output as an evaluation value of the work environment. The above α, β, and γ are parameters for normalization, and the parameter is set to a larger value as the parameter contributes more to the comfort level. For example, α = 3, β = 1, and γ2 are set.

  The environment information input unit 110 and the environment evaluation unit 11 can be realized as individual units. However, a sensor having an information processing capability that has been spreading in recent years, a so-called smart sensor (intelligent sensor). It is also possible to implement it.

  When the smart sensor is used, the function corresponding to the environment evaluation unit shown in FIG. 7 can be realized by causing the processor in the smart sensor to execute the process shown in FIG. 8, for example. In FIG. 8, first, the temperature t is input from the temperature sensor (step 11), and then the ideal temperature t0 is input (step 12). Next, the humidity h is input from the humidity sensor (step 13), and then the ideal humidity h0 is input (step 14). Next, the brightness L is input from the brightness sensor (step 15), and then the ideal brightness L0 is input (step 16). Next, Δt = | t-t0 |, Δh = | h-h0 |, ΔL = | L-L0 | are calculated (steps 17, 18, and 19), and their normalized values Δt ′ = αΔt, Δh ′ = βΔh. ΔL ′ = γΔL is calculated (step 20), and finally the comfort level k = 1 / (Δt ′ + Δh ′ + ΔL ′) is calculated (step 21). Such processing is repeatedly executed at regular intervals.

  Refer to FIG. 5 again. The information processing system includes a JPEG 2000 still image code data, a code input unit 121 that takes in the code data from the code storage unit 120, a code editing unit 122 that edits the code data input from the code input unit 121, and an environment evaluation unit. A comfort level determination unit 130 that performs a comparison determination between the comfort level k that is the evaluation result of 111 and one or more threshold values set by the threshold value setting unit 131 is included. The code input to the decoding unit 101 is a code after being edited by the code editing unit 122.

  Although only one block A surrounded by a broken line is shown in FIG. 5, there are generally a plurality of blocks A. In addition, a plurality of blocks B surrounded by broken lines may be provided corresponding to each block A, or one block B may be provided for a plurality of blocks A. In any form, only one set of the environment information detection means 110 and the environment evaluation means 111 may be provided.

  In a mode in which one block B common to a plurality of blocks A is provided, it is preferable that the threshold value can be set for each block A by the threshold value setting means 131, that is, for each worker. This is because there are individual differences in how the comfort level is felt (good or bad) depending on the worker, so the threshold may be changed depending on the individual difference, and the threshold may be changed depending on the type of work. This is because there may be cases.

  In a recent office environment, a client / server system in which a server device and a client device are connected by a LAN or the like is common. Therefore, in the case of a configuration in which one block B common to a plurality of blocks A is provided, it is generally preferable to adopt a system configuration in which the block A is mounted on the client device and the block B is mounted on the server device. The transfer path of the comfort level k from the environment evaluation unit 111 to the comfort level determination unit 130 may be wired or wireless. The code input means 121 may be a means for taking in code data via a network such as the Internet.

  FIG. 6 is a flowchart showing the flow of processing in block B. The code input unit 121 of the block B reads one frame (or several frames) of JPEG2000 still image code data or Motion-JPEG2000 moving image code data from the code storage unit 120 and inputs it to the code editing unit 122 ( step 1). The comfort level determination means 130 inputs the comfort level k from the environment evaluation means 111 (step 2), and compares and determines the comfort level k and the threshold value th set by the threshold value setting means 131 (step 3). If the result of the determination is Yes (k <th) (when it is determined that the degree of comfort k is low), the code editing means 122 performs an editing process for discarding some codes for the input code data (step 4). Then, the edited code data is output to the decoding means 101 of the block A (step 5). If the determination result is No (k ≧ th) (when it is determined that the comfort level k is high), the code editing unit 122 outputs the input code data as it is to the decoding unit 101 (step 5).

  Such processing is repeatedly executed at regular time intervals. Therefore, in the case of still image code data, the same still image code data is repeatedly input to the decoding means 101 at regular time intervals. In the case of moving image code data, code data is sequentially input to the decoding unit 101 in units of one frame (or in units of several frames).

  Further, in a form in which one block B is provided in common to a plurality of blocks A, when the common threshold th is used for all the blocks A, the same code data is applied to the decoding means 101 of the plurality of blocks A at step 5. You can enter. However, when the threshold value th is set for each block A (for each worker), the processing after step 2 is repeatedly executed for each block A using the corresponding threshold value th.

  Next, the relationship between the code editing by the code editing unit 122 and the image displayed on the display unit 104 will be described.

  Assume that the input code data to the code editing means 122 is, for example, resolution progressive code data (for example, JPEG2000 RLCP progressive code data) as shown in the upper part of FIG. When the comfort level k is high, the input code data is input to the decoding unit 101 as it is. Therefore, for example, an image as shown on the left side of FIG. On the other hand, when the comfort level k is low, code data obtained by discarding codes of the 1HL, 1LH, and 1HH subbands as shown in the lower part of FIG. An image in which the vertical and horizontal sizes are reduced by half (the resolution is reduced by half) is displayed as shown on the right side of FIG.

  The code may be discarded when the comfort level is high, and the code may not be discarded when the comfort level is low. Also, the level of comfort is determined in multiple stages using a plurality of threshold values, and from the subband code side of the highest resolution level of the code data, as the comfort level is lower (higher), more codes are discarded. Also good.

  It is assumed that the input code data is, for example, image quality progressive code data (JPEG2000 LRCP progressive code data) as shown in the upper part of FIG. When the comfort level k is high, the input code data is input to the decoding unit 101 as it is, so that an image with good image quality as shown on the left side of FIG. 12, for example, is displayed. On the other hand, when the comfort level k is low, the code editing unit 122 inputs a code in which the codes of layers 2 and 3 shown in the lower part of FIG. 11 are discarded to the decoding unit 101. An image with a low image quality as shown is displayed.

  The code may be discarded when the comfort level is high, and the code may not be discarded when the comfort level is low. Alternatively, the level of comfort may be determined in multiple stages using a plurality of thresholds, and more codes may be discarded as the comfort level is lower (or higher) from the lowest layer side of the code data.

  Further, it is assumed that the input code data is, for example, component progressive code data (JPEG2000 CPRL progressive code data) as shown in the upper part of FIG. When the comfort level k is high, the input code data is input to the decoding unit 101 as it is, so that a color image is displayed. On the other hand, when the comfort level k is low, code data in which the Cr and Cb components are discarded as shown in the lower part of FIG. 13 is input to the decoding unit 101 by the code editing unit 122, so that a monochrome image of only the luminance component is displayed. Will be.

  Note that when the comfort level is high, the Cr and Cb components may be discarded to display a monochrome image, and when the comfort level is low, the color image may be displayed without discarding the Cb and Cr components. Also, the level of comfort is determined in multiple stages using multiple thresholds, and the color of the displayed image is reduced or increased by increasing or decreasing the code discard amount of the Cb and Cr components as the comfort level decreases. You may make it make it.

Further, it is assumed that the input code data is, for example, code data divided into four tiles as shown in FIG. 14 , that is, position progressive code data in units of tiles. When the comfort level k is high, the input code data is input to the decoding unit 101 as it is, so that the entire image is displayed. However, when the comfort level k is low, the code editing unit 122 inputs the code data obtained by discarding the codes of the tiles 2 and 3 as shown in the lower part of FIG. An image from which the area is cut is displayed.

  FIG. 15 exemplifies the change in the display image due to the code discard of such position progressive code data. The left side is an image when the comfort level k is high, and the right side is an image when the level of comfort level k is low. is there.

  It is possible to perform similar code discarding in units of precincts. For example, in the case of code data of RCRL progression that does not perform tile division (it can be considered by replacing the tile in FIG. 14 with a precinct), when the comfort level k is high, the code data is input to the decoding means 101 as it is. An image including a precinct area is displayed. When the comfort level k is low, for example, code data in which the code of the precinct (2, 3) is discarded is input to the decoding unit 101, and an image in which the precinct area is cut is displayed. Can be made.

  It is also possible to discard the code when the comfort level is high and not discard the code when the comfort level is low. Alternatively, the level of comfort may be determined in multiple stages using a plurality of thresholds, and the tile or precinct that discards the code may be increased or decreased as the comfort level decreases.

  As described above, since the image reflecting the level of comfort of the work environment is displayed on the screen of the display means 104 that the worker watches during work, the worker can be surely aware of the deterioration of the work environment. Can be made.

  Here, a supplementary explanation will be given for the case of displaying Motion-JPEG2000 moving image code data. Each frame of Motion-JPEG2000 moving image code data is independently encoded with JPEG2000, and therefore decoding can be performed independently for each frame. When displaying such moving image code data, as described above, in step 1 of FIG. 6, code data is fetched frame by frame (or several frames) from the top frame, and when comfort level is high, when comfort level is low The process of inputting the code to the decompression means 101 and displaying it after the code discarding can be repeated at regular time intervals. However, code data of one frame (or several frames) from the first frame is input to the decompression means 101 as it is regardless of the comfort level, and the comfort level is determined during this period, and the next predetermined number is determined according to the determination result. Processing may be performed such that a necessary code discard is performed when a frame is input, a next comfort level determination is performed during this time, and a necessary code discard is performed when a next predetermined number of frames are input according to the determination result. .

  The JPEG 2000 still image code data and Motion-JPEG 2000 moving image code data can be changed in display image with respect to resolution, image quality, component, and position by simple code discard. However, it is also possible to use still image data or moving image code data encoded by another encoding method as long as similar code cancellation and decoding of the code data in which the code is discarded are possible.

As is clear from the above description, the block A and the block B of the information processing system can be realized by one or more programs using a computer constituted by a CPU, a memory, and the like. In other words, blocks A and B are realized by loading a program for causing a computer to function as a configuration means for blocks A and B or a configuration means for block A or block B and executing the program on a computer CPU. can do. This program may or may not include an application program as the business processing means 100. This is because it is often preferable to install such an application program on a computer as an independent program. Such a program and a computer-readable information recording (storage) medium such as a magnetic disk, an optical disk, a magneto-optical disk, and a semiconductor storage element on which the program is recorded are embodiments of the inventions of claims 10 and 12. .

In addition, as to the correspondence with the claims, the decoding means 101, the code editing means 122, and the code input means 121 constitute the “image data input means” described in claim 1 . The display control means 103, together with the display data storage means 102, constitutes "a means for displaying" according to claim 1.

[Embodiment 2]
FIG. 16 is a block diagram showing an overall configuration of a system according to Embodiment 2 of the present invention. In the system according to the present embodiment, the code editing unit 122 according to the first embodiment is omitted, and resolution conversion processing, smoothing filter processing, monochrome conversion processing, and clipping processing are performed on the decoded image data by the decoding unit 101. The image editing means 106 is provided to perform the determination, and the determination result by the comfort level determining means 130 is input to the image editing means 106.

  In this embodiment, since code editing is not performed, the code data read from the code storage unit 120 by the code input unit 121 and input to the decoding unit 101 is JPEG2000 still image code data or Motion-JPEG2000 code data. It is not limited to moving image code data, and may be still image or moving image code data based on an arbitrary encoding method. For example, JPEG still image code data, Motion-JPEG moving image code data, MPEG moving image code data using inter-frame differences, and the like may be used.

  FIG. 17 is a flowchart showing a flow of an operation of inputting still image or moving image code data by the code input unit 121 and displaying the image on the display unit 104. This operation is repeated at regular time intervals.

  Code data of a still image or code data of one frame (or several frames) of a moving image is input to the decoding unit 101 by the code input unit 121 (step 31), the code data is decoded by the decoding unit 101, and the decoded image Data is input to the image editing means 106 (step 32). The comfort level k is input from the environment evaluation unit 111 to the comfort level determination unit 130 (step 33), and the comfort level determination unit 130 performs a comparison determination between the threshold value th set by the threshold value setting unit 131 and the comfort level k. The result is input to the image editing means 106 (step 34). If the determination result is No (comfort level k is higher than the threshold th), the image editing unit 106 does not perform image editing, and the image data decoded by the decoding unit 101 is stored as display data (2) as display data. The information is written in the means 102 and displayed on the display means 104 by the display control means 103 (step 36). If the determination result is Yes (comfort level k is lower than the threshold th), the image editing unit 106 performs image editing processing on the decoded image data, and the edited image data is stored as display data (2) as display data. It is written in the means 102 (step 106), and it is displayed on the display means 104 by the display control means 103 (step 36).

  An example of the image editing process in step 35 is a resolution conversion process for lowering the resolution. For example, an image as shown on the left side of FIG. 10 is displayed when the comfort level is high, and as shown on the right side of FIG. 10 when the comfort level is low. A reduced image is displayed. Note that the resolution conversion process may be performed when the comfort level is high, and the resolution conversion process may not be performed when the comfort level is low. Alternatively, the level of comfort may be determined in multiple stages using a plurality of threshold values, and the resolution may be converted in stages according to the level of comfort.

  Another example of the image editing process in step 35 is a smoothing filter process. When the comfort level is high, for example, a clear image as shown on the left side of FIG. 12 is displayed, but when the comfort level is low, FIG. An image with reduced sharpness as shown on the right side is displayed. The smoothing filter process may be performed when the comfort level is high, and the smoothing filter process may not be performed when the comfort level is low. Alternatively, the level of comfort may be determined in multiple stages using a plurality of threshold values, and the smoothing degree of the smoothing filter process may be changed in stages according to the level of comfort.

  Another example of the image editing process is a monochrome conversion process in which a color image is displayed when the comfort level is high, and a monochrome image is displayed when the comfort level is low. Note that monochrome conversion may be performed when the comfort level is high, and monochrome conversion may not be performed when the comfort level is low. Alternatively, the level of comfort may be determined in multiple stages using a plurality of thresholds, and the color of the image may be changed in stages according to the level of comfort.

  Another example of the image editing process is a clipping process. When the comfort level is high, for example, an image as shown on the left side of FIG. 15 is displayed. When the comfort level is low, the image editing process is shown on the right side of FIG. An image in which a part of the original image is cut off is displayed. It is also possible to perform the cutting process when the comfort level is high and not to perform the cutting process when the comfort level is low. Alternatively, the level of comfort may be determined in multiple stages using a plurality of thresholds, and the area of the cutout region may be changed in stages according to the level of comfort.

  As described above, since the image reflecting the comfort level of the comfort level of the work environment is displayed on the screen that the worker watches, the worker can be surely aware of the deterioration of the work environment.

[Embodiment 3]
FIG. 18 is a block diagram showing an overall configuration of a system according to Embodiment 3 of the present invention. In the first and second embodiments, the display of display data (image data) different from the display data of the job processing unit 100 is changed according to the comfort level determination result. This is achieved by changing the display of the display data of the business processing means 100 according to the comfort level determination result. The display disturbance / restoration means 107 in FIG. 18 is a means provided for changing the display of such display data in accordance with the comfort level determination result.

  FIG. 19 is a flowchart for explaining the operations of the comfort level determination means 130 and the display disturbance / restoration means 107. This operation is repeatedly executed at regular time intervals.

  First, the comfort level determination means 130 inputs the comfort level k from the environment evaluation means 111 (step 41), and compares and determines the threshold value th and the comfort level k set by the threshold value setting means 131 (step 42). When the comfort level k is lower than the threshold value th (step 42, Yes), it is checked whether the display of the display data is in a disturbed state (step 43). Performs a process of disturbing the display of the display data on the display data storage means 102, for example, a process of intentionally changing the character code by adding a constant to the character code in the display data (step 44). When the display data subjected to this processing is displayed on the display means 104 by the display control means 103, so-called “garbage” occurs. Therefore, the worker can be surely aware of the deterioration of the working environment.

  When it is determined in step 42 that the comfort level is higher than the threshold th, the display disturbance / restoring means 107 checks whether the display state is normal (step 45). When it is not in the normal display state (when it is already in the display disturbance state), the display disturbance / display means 107 performs a process for restoring the character code of the display data on the display data storage means 102 (step 46), and the display data is normal. Restore the displayed state so that the worker can perform normal work.

  In order to facilitate the restoration to the normal display, the display data before the disturbance processing is stored in the display data storage means 102 in step 44, and the normal display data in which the disturbance processed display data is stored in step 46. A method of replacing with may be used.

  Further, the display disturbance method when the comfort level is low is not necessarily limited to the method of causing “garbled characters”. For example, when the comfort level is low, the display disturbing / restoring means 107 designates an extremely large or small font size or a font type that is not normally used to the display control means 103, thereby making the display data unnatural. It is possible to take a method such as displaying in various forms. In short, the display data display may be changed so that the operator can easily recognize that the comfort level is low.

Note that also in the system according to the present embodiment, the block A and the block B can be realized by one or more programs using a computer including a CPU, a memory, and the like. In other words, blocks A and B are realized by loading a program for causing a computer to function as a configuration means for blocks A and B or a configuration means for block A or block B and executing the program on a computer CPU. can do. This program may or may not include an application program as the business processing means 100 .
