## Background
TECHNICAL FIELD
The disclosure relates to a picture editor which can analyze color pictorial data of a plurality of color pictures to obtain pictorial information code, add the pictorial information code to the color pictorial data, pick out and display the color pictorial data matching designated pictorial information, according to the pictorial information code.
BACKGROUND
As significant proliferation of personal computers (PC) proceeds, a digital still camera (hereinafter, a “digital camera”) for providing pictures to be displayed in the PC has been also widely diffused in recent years. Using the PC and the digital camera increases works of selecting some pictures to be printed from the pictures loaded into the PC from the digital camera, and of selecting some pictures which match the image from the loaded pictures to make a scrapbook. A user selects the picture from an index of the pictures displayed in a video monitor with a cursor stopping at the desired image after moving along the pictures one by one from the first picture. Therefore, even if it is known that the desired picture is in the last, the user needs to move the cursor along the pictures one by one to the last, which takes a lot of time to select the picture.
To solve the above problem, Japanese patent publication laid-open No. H10(1998)-126724 discloses functions of displaying plural thumbnail pictures in predetermined arrangement imported from a digital camera to a video monitor, showing a cursor in a freely movable way on a screen of the video monitor, acquiring its position (coordinate), considering a picture on which the cursor is placed as a printing output picture candidate, fetching a picture of high resolution corresponding to the selected thumbnail picture from the digital camera to a memory when confirmation is inputted, showing the picture on the video monitor, and adding an index to the displayed picture.
The picture selecting process disclosed in the '724 publication is the process in which the plural pictures loaded to the memory are displayed as an m x n array in a predetermined size on a displaying device, and the picture on which the cursor is placed is considered as the printing output picture candidate. Thus, the process still has the problem that it takes much time to select the pictures. Even when it is intended to select the picture of the bright and intense yellow image, it is not clear whether the picture has the brightest and the most intense image among the plural pictures loaded to the memory.
SUMMARY
At least some example aspects of the disclosure has been made in view of the above circumstances and has an object to overcome the above problems and to provide a picture editor which can analyze color pictorial data of a plurality of color pictures to obtain pictorial information code, add the pictorial information code to the color pictorial data, pick out and display the color pictorial data matching designated pictorial information, according to the pictorial information code.

Operation of the picture editor 1 of the above structures will be explained with reference to FIGS. 5 to 16. A “Step” in a flowchart is abbreviated to “S”.
FIG. 5 is a state transition diagram of the picture editor. The operation of the picture editor 1 is briefly explained with FIG. 5.
Firstly, the picture editor 1 is turned on (S1). An edit process is selected with the keyboard 14 or the mouse 15 (S2). The color pictorial data is imported from the digital camera 10 and stored in the pictorial data storing unit 3. The stored color pictorial data is loaded to the pictorial data analyzing unit 4 (S3). The color pictorial data is analyzed in the pictorial data analyzing unit 4 (S4). Retrieval information according to the analysis of the color pictorial data is added to the imported color pictorial data (S5).
When a scrapbook 19 described later (see FIG. 14) is created by using the color pictorial data edited as above, the color picture which matches the image to be stuck thereon should be selected. For that purpose, the picture editor 1 is set in a preview mode with the keyboard 14 or the mouse 15 (S6). The retrieval information which matches the image is inputted (S7). The color image which fit the image best is selected from the plurality of the color pictures which are picked out by a matching pictures retrieve process and displayed on the video monitor 13 (S8). The selected color picture is placed in the preview mode (S6). The completed scrapbook 19 is displayed on the video monitor 13, and printed on the printer (S9). The picture editor 1 is turned off.
Next, each process will be explained in detail.
Firstly, a pictorial data analyze process is explained with reference to FIG. 6. FIG. 6 is a flowchart of the pictorial data analyze process. The pictorial data analyzing unit 4 performs the operation to analyze each kind of the pictorial information on the brightness (V), the saturation (S) and the hue (H) of the color pictorial data stored in the pictorial data storing unit 3, based on the RGB data (R: red, G: Green, B: Blue), and to digitize the color pictorial data.
The pictorial data analyzing unit 4 is initialized (S101). The color pictorial data stored in the pictorial data storing unit 3 is imported, and all the pixels of the color pictorial data are searched. It is verified whether all the pixels of the color pictorial data are searched (S102). If all the pixels are not searched (S102, NO), the RGB data of one unsearched pixel is loaded (S103). The operation is performed to digitize the brightness (V) and the saturation (S) of the loaded RGB data (S104). Next, the hue (H) is digitized. In S105, the pictorial data analyzing unit 4 verifies whether the R data is the maximum value. If the R data is not the maximum value (S105, NO), the flow advances to S107. If the R data is the maximum value (S105, YES), the flow advances to S106. In S106, the operation is performed to digitize the hue (H) based on the proportion of the difference between B and G in chromatic color, and then the flow goes on to S107. In S107, the pictorial data analyzing unit 4 verifies whether the G data is the maximum value. If the G data is not the maximum value (S107, NO), the flow advances to S109. If the G data is the maximum value (S107, YES), the flow goes on to S108. In S108, the operation is performed to digitize the hue (H) based on the proportion of the difference between B and R in the chromatic color and a hue position of G saturated color, and then the flow goes on to S109. In S109, it is verified whether the B data is the maximum value. If the B data is not the maximum value (S109, NO), the flow advances to S111. If the B data is the maximum value (S109, YES), the flow goes on to S110. In S110, the operation is performed to digitize the hue (H) based on the proportion of the difference between G and R in the chromatic color and a hue position of B saturated color, and then the flow goes on to S111. In S111, the hue position H is converted into a value at the time of setting the value of the whole hue position 100. In S112, a representative hue value h (H) of the one pixel is increased by one, and the flow returns to S102. The process through S102 to S112 is performed on all the pixels of the color pictorial data to analyze and digitize each kind of the pictorial information on the brightness (V), the saturation (S) and the hue (H) of the color pictorial data based on the RGB data. When all the pixels are searched, (S102, YES), the flow ends.
Next, a retrieval information add process will be explained with reference to FIGS. 7 to 9. FIGS. 7, 8 and 9 are flowcharts of the retrieval information add process. In this flow, each kind of the averaged pictorial information on the brightness, the saturation and the hue of the color pictorial data which is analyzed and digitized in the pictorial data analyze process shown in FIG. 6 is added to the color pictorial data stored in the pictorial data storing unit 3. The information code of the pictures divided into the groups, according to the averaged pictorial information of the pictures and the images of the color pictorial data of the pictures which are classified, is added to the color pictorial data stored in the pictorial data storing unit 3.
In S201, the operation is performed to obtain an average value V/N of the sum of the brightness of all the pixels. A recording process of the average value V/N in the Tag No. 2 of the retrieval information adding data 16 shown in FIG. 3 is set up. The flow advances to S202, and the operation is performed to obtain an average value S/N of the sum of the saturation of all the pixels. The recording process of the average value S/N in the Tag No. 3 of the retrieval information adding data 16 shown in FIG. 3 is set up. The flow advances to S203, and the operation is performed to obtain an average value MAXh(i)/N of the mode of the hue distribution of all the pixels. The retrieval information adding unit 5 sets up the recording process of the average value MAXh(i)/N in the Tag No. 4 of the retrieval information adding data 16 shown in FIG. 3. At the same time, the operation is performed to obtain a position i of the mode of the hue distribution of all the pixels, and sets up the recording process of the value of the position i in the Tag No. 5.
The flow goes on to S204. In S204, it is determined whether the color image is automatically set based on a table of ranges for color-image automatic setting 17 shown in FIG. 10, or the color image is manually set in a color-image manual setting screen 18 shown in FIG. 11.
FIG. 10 is an explanatory diagram of the table of ranges for color image automatic setting. As shown in FIG. 10, in the table of ranges for color-image automatic setting 17, the averaged values of the pictorial information are divided into the plurality of the ranges, and the color image of the color picture is assigned to each of the ranges with a color image number. Therefore, the averaged values of each kind of the pictorial information can be applied to any divided ranges in the table of ranges for color-image automatic setting 17, so that the color image of the color picture can be picked out with the color image number.
FIG. 11 is an explanatory view of a manual setting process of the color image to the loaded picture. The color image of the color-image set picture 18a displayed on the color-image manual setting screen 18 can be selected from a keyword group 18b, and determined with a decide button 18f This will be explained later in detail.

Now that the pictorial data analyze process shown in FIG. 6 and the pictorial information add process shown in FIGS. 7 to 9 have been performed for each of the color pictorial data, the retrieval information is added to the color pictorial data of all the pictures stored in the pictorial data storing unit 3.
Next, a retrieval information input process for picking-out of the desired color image data by the retrieval information will be explained with reference to FIG. 12. FIG. 12 is a flowchart of the retrieval information input process. It is noted that the brightness, the saturation and the hue corresponds to lightness, vividness and tone respectively in the flowchart.
Firstly, the search criteria is selected in S301. In S302, it is judged whether the search criteria is the lightness or not. If it is the lightness (S302, YES), the flow advances to S303 wherein the desired lightness is defined. Next, the flow goes on to S304 wherein the desired number of the pictures to be picked out is designated, and then to S312.
In S302, if the search criteria is not the lightness (S302, NO), the flow advances to S305 and it is judged whether the search criteria is the vividness or not. If it is the vividness (S305, YES), the flow advances to S306 wherein the desired vividness is defined. Next, the flow goes on to S307 wherein the desired number of the pictures to be picked out is designated, and then to S312.
In S305, if the search criteria is not the vividness (S305, NO), the flow advances to S308 and it is judged whether the search criteria is the tone or not. If it is the tone (S308, YES), the flow advances to S309 wherein the desired tone is defined. Next, the flow goes on to S310 wherein the desired number of the pictures to be picked out is designated, and then to S312.
In S308, if it is not the tone (S308, NO), the flow advances to S311. In S311, the desired color image is selected as the search criteria, and then the flow advances to S312.
In S312, a search button is selected to start the search. After the selection, the flow goes on to S313 and a matching pictures retrieve process is performed by the defined search criteria.
It is noted that each of the search criteria of the lightness, the vividness and the tone is defined individually in the retrieval information input process shown in FIG. 12, but may be done for the combination of them.
Next, the matching pictures retrieve process in which the pictures are picked out by the search criteria defined in FIG. 12 will be explained with reference to FIG. 13. FIG. 13 is a flowchart of the matching pictures retrieve process.
Firstly, matching pictures are load in S401, and it is judged whether the search criteria is the lightness or not in S402. If it is the lightness (S402, YES), the flow advances to S403 wherein the designated number of the pictures which match the defined lightness are picked out in descending order, and then ends.
In S402, if the search criteria is not the lightness (S402, NO), the flow advances to S404 and it is judged whether the search criteria is the vividness or not.

In S406, if the search criteria is not the tone (S406, NO), the flow advances to S408 wherein the pictures which match the selected color image are picked out in descending order, and then ends.
Next, the screen display of the video monitor 13 which is connected to the picture editor 1 being operated as above will be explained.
The screen display of FIG. 11 is explained firstly. FIG. 11 is the explanatory view of the manual setting process of the color image to the loaded image. This screen display is shown when “manual” is selected for setting the color image in the retrieval information add process. In the color-image manual setting screen 18 displayed in the video monitor 13, there are shown the color-image set picture 18a, the keyword group 18b for the selection of the color image, a next page button 18c for going to the next page, a previous page button 18d for going back to the previous page, a page number input/page number display 18e, a decide button 18f for selecting the color image, and a correct button 18g for changing the color image.
The abovementioned display screen is used as follows: the color-image set picture 18a is selected with the next page button 18c and the previous page button 18d. The color image which matches the color-image set picture 18a is selected from the keyword group 18b for the selection of the color images, and decided with the decide button 18f. The page number displayed at the time is shown in the page number input/page number display 18e. If there is a page to be modified, the page to be modified is selected with the next page button 18c and the previous page button 18d, and the information of the image is reset with the correct button 18g. After that, the color image which matches the color-image set picture 18a is selected again from the keyword group 18b and determined with the decide button 18f. The color image is manually added to the color pictorial data stored in the pictorial data storing unit 3 while the pages are forwarded one by one. The abovementioned operation is performed with a pointer of the mouse 15. The display screen in FIG. 11 shows that “Cool” of the color image No. 20 is selected for the 8th of 1000 (8/1000) color picture. It is noted that it may be possible to select the page directly with the keyboard 14.
Next, one example of using the picture editor 1 will be explained with reference to the screen display of the video monitor 13 shown in FIGS. 14 to 16. FIG. 14 is an exemplary view of the screen display of the whole preview for making of the scrapbook. FIG. 15 is an explanatory view of the automatic retrieval of the image having the desired lightness, vividness, and tone from the entire color pictorial data. FIG. 16 is an explanatory view of the automatic retrieval of the image having the desired color image from the entire color pictorial data.
For making of the scrapbook 19 as shown in FIG. 14, items 19a to 19e matching the image read from the pictorial data of the respective items are stuck on the scrapbook 19. When the need for the color picture having the slight lightness comes about during the sticking process, it takes much time and is an onerous task for a user to search voluminous color pictures one by one to find the desired color picture. Moreover, the color picture can be hardly selected from the voluminous pictures which match the search criteria and have no extreme differences. Therefore, the simple process of loading the color pictorial data which matches the image by using the picture editor 1 will be explained.
Firstly, the screen display of the video monitor 13 is changed to the screen display as shown in FIG. 15 by key entry with the keyboard 14. Herein, the screen display is explained in detail. In a picture automatic retrieval screen 20 of the desired HSV (H: Hue, S: Saturation, V: Brightness) displayed in the video monitor 13, matching pictures 20a, 20b and 20c which match the search criteria are displayed in descending order. It is possible to scroll the screen down to see more matching pictures if any by a scroll button 20r. The four words as search criteria are “lightness”, “vividness”, “tone” and “color image”. At each heads of signs of the search criteria, there are placed a spot 20d for defining the lightness, a spot 20e for defining the vividness, a spot 20f for defining the tone and a spot 20g for defining the color image. When one of the spots is selected with the mouse 15, the selected spot turns to a different color, which means the search criteria of the selected spot has been designated. At each ends of the signs of the search criteria, there are placed a slider 20h for setting the level of the lightness, a slider 20k for setting the vividness, and a slider 20m for setting the tone. When one of the spots is selected, a controller of the corresponding slider turns to a different color. Furthermore, a number of picture display part 20n which displays a number of the matching pictures, inputted with the keyboard 14, is placed with a search button 20p. 
The abovementioned display screen is used as follows: when the spot 20d for defining the lightness is selected with the mouse 15, the spot 20d turns the different color, which means the lightness has been selected as the search criteria. As mentioned above, the controller of the slider 20h also turns the different color. The level of the lightness is set at a position indicating the slight lightness by the controller being moved with the mouse 15. Next, “5” is inputted with the keyboard 14 as the number of the pictures to be retrieved, and the search button 20p is selected with the mouse 15. The search starts, and then the 5 matching pictures which match the defined lightness are displayed in descending order from the left side. In this case, only three images are displayed. The scroll button 20r is selected with the mouse 15 to scroll the screen down, so that the other two more pictures can be displayed. If the displayed pictures do not match the image, other matching pictures can be found by a fine-tuning of the controller of the slider 20h. In this case, the leftmost matching picture 20a shown first is the color picture which has the desired lightness. The matching picture 20a is loaded, and stuck at a position of the item 19b on the scrapbook 19 after the display goes back to the screen display of FIG. 14. Finally, the scrapbook 19 has been finished.
When the “color image” is selected as the search criteria in the picture automatic retrieval screen 20 to define the desired HSV shown in FIG. 15, a color image automatic retrieval screen 21 shown in FIG. 16 is displayed in the screen display of the video monitor 13. In the color image automatic retrieval screen 21 displayed in the video monitor 13, retrieved matching pictures 21a, 21b and 21c are displayed in descending order. It is possible to scroll the screen down to see more matching pictures if any by the scroll button 21d. A keyword group 21e for the selection of the color image, a retrieve button 21f for the retrieval of the color image, and a matching picture number display 21g for the display of the number of the retrieved chosen pictures are displayed.
The color image automatic retrieval screen 21 is used as follows: when the color image automatic retrieval screen 21 shown in FIG. 16 is displayed, the desired color image is selected from the keyword group 21e for the selection of the color image with the mouse 15. The retrieve button 21f is selected with the mouse 15, and then all of the retrieved matching pictures 21a, 21b and 21c which match the selected color image are displayed in descending order. Further, the number of the matching pictures is shown in the matching picture number display 21g. 
The screen display in FIG. 16 shows that “Cool” is selected from the keyword group 21e for the selection of the color image, and then all of the retrieved matching pictures 21a, 21b and 21c which are retrieved by the retrieve button 21f are displayed in descending order. The matching picture number display 21g shows that the number of the matching pictures is 10.
As described above, the desired color pictorial data can be obtained by being automatically selected from the keyword group 21e for the selection of the color image. In this case, the retrieved matching picture 21a is the desired color pictorial data, so that the matching picture 20a can be stuck at the position of the item 19b on the scrapbook 19 after the display goes back to the screen display of FIG. 14.
