[First embodiment]
A. Configuration of Digital Camera FIG. 1 is a block diagram showing an electrical schematic configuration of a digital camera 1 that implements the image reproducing apparatus of the present invention.
The digital camera 1 includes a CCD 2, a DSP / CPU 3, a TG (timing generator) 4, a unit circuit 5, a DRAM 6, a flash memory 7, a ROM 8, a key input unit 9, an image display unit 10, an audio processing unit 11, and a card I / F 12. The card I / F 12 is connected to a memory card 13 that is detachably attached to a card slot of the digital camera 1 (not shown).

  The CCD 2 photoelectrically converts the projected subject and outputs it to the unit circuit 5 as an imaging signal. The CCD 2 is driven in accordance with a predetermined frequency timing signal generated by the TG 4. A unit circuit 5 is connected to TG4. The unit circuit 5 includes a CDS (Correlated Double Sampling) circuit that holds the image pickup signal output from the CCD 2 by correlated double sampling, a gain adjustment amplifier (AGC) that amplifies the image pickup signal, and a digital signal of the amplified image pickup signal. An output signal of the CCD 2 is sent to the CPU 2 as a digital signal through the unit circuit 5.

The image display unit 10 includes a color LCD and its driving circuit, and displays the subject imaged by the CCD 2 as a through image when in the shooting standby state, and is read out from the storage memory card 13 and expanded when the recorded image is reproduced. The recorded image is displayed. The image display unit 10 corresponds to display means of the present invention.
The key input unit 9 includes a plurality of operation keys such as an execution key, a cancel key, a cursor key, and a mode key, and outputs an operation signal corresponding to the user's key operation to the DSP / CPU 3. The key input unit 9 also has a function as a designating unit of the present invention. The DRAM 6 is used as a buffer memory for temporarily storing digitized subject image data after being imaged by the CCD 2, and in the DSP / CPU 3. Also used as working memory.

The sound processing unit 11 includes a built-in microphone, an amplifier, an A / D converter, a built-in speaker, a D / A converter, and the like. When shooting a moving image with sound, the sound processing unit 11 converts sound input to the built-in microphone into a digital signal. Send to DSP / CPU3. The audio data sent to the DSP / CPU 3 is sequentially stored in the DRAM 10 and recorded on the memory card 13 together with the image data generated by the DSP / CPU 3.
In addition, when reproducing a moving image with sound, the sound processing unit 11 outputs sound based on sound data attached to each image or a searched color name described later from a built-in speaker. In addition, various notification sounds are reported by built-in speakers as necessary. The audio processing unit 11 corresponds to the audio output unit of the present invention.

The DSP / CPU 3 is a one-chip microcomputer that has various digital signal processing functions including image file compression / decompression processing and controls each part of the electronic camera 21.
In particular, the DSP / CPU 3 determines whether image data to be reproduced has been selected from the image data recorded on the memory card 13 by the user's operation of the key input unit 9. This determination is made based on whether or not an operation signal corresponding to selection of image data has been sent from the key input unit 9.
When the DSP / CPU 3 determines that image data is selected, the DSP / CPU 3 reads the image data via the card I / F 12, expands the read image data, and causes the image display unit 10 to display the image. This function corresponds to the image display control means of the present invention.

The DSP / CPU 3 determines whether or not a part for which a color name is to be displayed is designated by the user's operation of the key input unit 9.
Here, when an image is displayed on the image display unit 10, the user moves the pointer by operating the cursor, moves the pointer to a portion of the image where the name of the color is desired, and operates the execution key (designation). means). When an operation signal corresponding to the operation of the execution key is sent from the key input unit 9, the DSP / CPU 3 determines that the display designation of the color name has been performed.
When the DSP / CPU 3 determines that the display designation of the color name has been performed, the DSP / CPU 3 acquires the RGB value (color information) of the pixel at the position where the pointer is placed. This function corresponds to the acquisition means of the present invention. Then, the most appropriate color name is searched from the acquired RGB values using the color name table recorded in the ROM 8. This function corresponds to the search means of the present invention.

  Then, the DSP / CPU 3 notifies the user of the searched color name. This function corresponds to the notification means of the present invention. As a notification method, the searched color name may be displayed on the image display unit 10 (display control means), or the searched color name may be output from the built-in speaker of the audio processing unit 11 (audio output). Control means). Further, both image display and audio output may be performed.

  In the flash memory 7 and the ROM 8, necessary control programs and necessary data (color name table) are recorded in each part of the DSP / CPU 3, and the DSP / CPU 3 operates in accordance with the programs, and thereby the image of the present invention. Functions as display control means, acquisition means, search means, notification means, display control means, and audio output control means.

FIG. 2A shows a color name table recorded in the ROM 8.
In the color name table, color names corresponding to RGB values are recorded.
That is, 27 color names of black, dark blue, blue, green,..., Yellow, light yellow, and white are stored, and RGB values corresponding to the color names are recorded.
Here, the R value, the G value, and the B value are each 0 to 255, and each of them is divided into three to determine the corresponding color names. That is, the RGB value is divided and recorded in a range from “0 to 85”, a range from “86 to 170”, and a range from “171 to 255”, and the number of colors determined by the RGB value is three. X 3 x 3 with 27 colors.
Therefore, when the R value “94”, the G value “211”, and the B value “20”, the R value “94” is in the range of 86 to 170, and the G value “211” is in the range of 171 to 255. Since the B value “20” is in the range of 0 to 85, the color name corresponding to the RGB value is “lime”.

Although the RGB value is divided into three, the number of divisions is arbitrary, and it is not necessary to divide RGB equally. That is, the R value may be divided into three, the G value may be divided into five, and the B value may be divided into four. In this case, the number of color names is 3 × 5 × 4, which is 60.
Further, although there is one color name for the RGB values, a plurality of color names may be provided for the RGB values. For example, in addition to the general color names as shown in FIG. 2, a plurality of color names such as “Z8102 object color name” and “common color name” of JIS standard are recorded corresponding to one RGB value, and the user's operation You may make it change a color name by.
For example, a greenish blue may be recorded with a plurality of color names such as “Asagi Color”, “Nando Color”, “Turquoise Blue”, and “Marine Blue”.

B. Operation of Digital Camera 1 The operation of the digital camera 1 will be described with reference to the flowchart of FIG.
When the image reproduction mode is set by the user operating the key input unit 9, it is determined in step S1 whether or not image data to be displayed is selected. This determination is made based on whether or not an operation signal corresponding to image data selection is sent from the key input unit 9.
If image data has been selected, the process proceeds to step S2. If there is no selection, the process remains in step S1 until the selection is made.

In step S2, the selected image data is read from the memory card 13 via the card I / F 12, and the read image data is expanded and displayed on the image display unit 10. Here, it is assumed that an image as shown in FIG. 4 is displayed.
Here, the image shown in FIG. 4 includes an object 21 having a ribbon-like shape, an object 22 having a rectangular parallelepiped shape, and an object 23 having a cylindrical shape. The object 21 has a red color, the object 22 has a dark blue color, and the object 23 has an orange color.

Next, the process proceeds to step S3, and it is determined whether or not designation of color name display has been performed. If the designation of color name display is performed, the process proceeds to step S4, and if not, the process remains in step S3 until it is performed.
Here, when the image is displayed, the user moves the pointer to a location where the user wants to know the color name by operating the cursor key. When the movement of the pointer is completed, that is, when the pointer is moved to a location where the name of the color is desired, the execution (color display) key is operated. When the operation of the color display key is performed, it is determined that the color name display is designated. Here, as shown in FIG. 4, it is assumed that the cursor is moved to the front side of the object 22 and the color display key is operated.

Next, in step S4, the RGB value of the pixel at the position where the color name display is designated, that is, the position of the pointer when the color display is designated is acquired. That is, with reference to FIG. 4, the RGB value at the position where the pointer is set, that is, the position of the black point 24 is acquired. For example, the acquired RGB values are R value “21”, G value “46”, and B value “135”. It should be noted that only the RGB value of the pixel at the center of the image may be acquired, or a predetermined position (a position focused when the image is photographed, or specified by the user in advance). The RGB value of the pixel at the set position or a plurality of predetermined positions may be automatically selected. In this case, the RGB value of the pixel is acquired without specifying the color name display.
Next, in step S5, the color name at the position of the pointer (the position of the black dot 24) is searched using the detected RGB value and the color name table recorded in the ROM 8. That is, the color name corresponding to the read R value “21”, G value “46”, and B value “135” is searched. Since the R value “21” is in the range of 0 to 85, the G value “46” is in the range of 0 to 85, and the B value “135” is in the range of 85 to 170, the position of the pointer (black dot 24 The name of the color at () is “dark blue”.

In step S 6, the searched color name, that is, “dark blue” is displayed on the image display unit 10. In addition, you may alert | report "it is dark blue" with an audio | voice. Moreover, you may make it alert | report by an audio | voice with an image display.
The color name may be switched by the user's operation of the key input unit 9. For example, it may be changed to “color name of Z8102 object” or “common color name” of JIS standard.

C. As described above, when the image reproduction mode is set and the image data is selected, the image of the selected image data is displayed on the image display unit 10. Then, the user looks at the image, operates the key input unit 9, puts the pointer on the part for which the name of the color is desired, and presses the execution key. Then, it is determined that the color name display has been designated, and the RGB value of the pixel at the position of the combined pointer is acquired, and the color name is searched using the acquired RGB value and the color name table recorded in the ROM 8. The user is notified of the searched color name.

D. As described above, in the first embodiment, since the color name of the designated part of the color name display is notified, even when the color is unknown, the user can easily know the color name. be able to.
It is also convenient when you want to buy the same paint or fabric as the colors shown in the image.
In addition, even visually impaired persons can easily identify how many of these colors are useful in daily life.

  The image reproducing apparatus in the first embodiment is not limited to the above embodiments, and may be a mobile phone, a PDA, a digital video camera, a personal computer, etc. Any device can be used.

[Second Embodiment]
Next, a second embodiment will be described.
In the second embodiment, a color name is searched when an image is captured, the retrieved color name is recorded in association with the captured image data, and the associated color name is displayed when the image data is reproduced. It is.

E. Configuration of Digital Camera 1 The second embodiment also implements the image recording apparatus of the present invention by using a digital camera 1 having the same configuration as that shown in FIG.
The digital camera 1 according to the second embodiment differs from the first embodiment in configuration functions in the following points.
Regarding Image Shooting Processing When the image capturing mode is set by the user's operation of the key input unit 11, the DSP / CPU 3 starts imaging by the CCD 2 and displays the captured subject on the image display unit 10 as a through image.

Then, it is determined whether or not the user has pressed the shutter button. This determination is made based on whether or not an operation signal corresponding to the operation of pressing the shutter button is sent from the key input unit 9.
When the DSP / CPU 3 determines that the shutter button has been pressed, it starts still image shooting processing. Here, even-numbered pixel signals and odd-numbered pixel signals in one screen are sequentially output to the CCD 4 at a relatively long output imaging timing, and the data for the entire area is acquired in the buffer memory (DRAM 6). This function corresponds to the image acquisition means of the present invention.
Then, the RGB value for each pixel of the image data stored in the DRAM 6 is acquired for each pixel. This function corresponds to the acquisition means of the present invention. In addition, position data indicating where the pixel is located in the image is also acquired.

The DSP / CPU 3 searches for a color name for each pixel based on the acquired RGB value for each pixel. At this time, a search is performed using the color name table recorded in the ROM 8. This function corresponds to the search means of the present invention.
Then, the retrieved color name is associated with the position data of the pixel from which the color name is retrieved, and the retrieved color name is associated with the acquired image data and recorded in the memory card 13. This function corresponds to the recording control means of the present invention.

Image Reproduction Process Next, a process for reproducing image data captured by the above image capturing process will be described.
Similar to the first embodiment, when image data is selected by the user's operation of the key input unit 9 and displayed on the image display unit 10, the user knows the name of the color in the image. Move the pointer to the desired part and press the Enter key.

  When an operation signal corresponding to pressing of the execution key is sent from the key input unit 9, the DSP / CPU 3 determines that the color name display is designated, and from the position data where the designated pointer is located in the image. The color name corresponding to the position data and recorded in association with the selected image data is read from the memory card 13. Then, the read color name is notified. This function corresponds to the notification means of the present invention. As a notification method, the read color name may be displayed on the display device 10 (display control means), or the searched color name may be output from the built-in speaker of the audio processing unit 11 (audio output). Control means).

H. Operation of Digital Camera 1 The image shooting operation of the digital camera 1 will be described with reference to the flowchart of FIG.
When the image capturing mode is set by the user's operation of the key input unit 9, imaging by the CCD 2 is started and a through image of the subject is displayed on the image display unit 10 in step S11.
In step S12, it is determined whether the shutter button has been pressed. This determination is made based on whether or not an operation signal corresponding to pressing the shutter button is sent from the key input unit 9. If the shutter button is pressed, the process proceeds to step S13. If the shutter button is not pressed, the process stays at step S12 and continues to display the through image until the button is pressed.

Next, in step S13, a still image shooting process is performed. In this case, even-numbered pixel signals and odd-numbered pixel signals in one screen are sequentially output to the CCD 2 at a relatively long output imaging timing, and the data of the entire surface is captured in the buffer memory (DRAM 6). The process of compressing image data is started.
Next, the process proceeds to step S14, and RGB values and position data for each pixel of the image data are acquired. Position data refers to data indicating the position to which a pixel corresponds in the entire image of image data.

Next, the process proceeds to step S15, and a color name corresponding to the detected RGB value for each pixel is searched based on the color information table recorded in the ROM 8. Note that the color name corresponding to the RGB value for each pixel may not be searched, and only the color name at the center of the image may be automatically searched, or a predetermined position (the image is captured). Sometimes, only the color name of the focused position, the setting position designated in advance by the user, a plurality of predetermined positions, etc.) may be automatically searched. When a plurality of color names are recorded in the ROM 8 corresponding to the RGB values, a plurality of color names are searched for each pixel.
In step S16, the retrieved color name and the position data in the image of the pixel from which the color name is retrieved are recorded in the memory card 13 in association with the compressed image data. At this time, the pixel position data and the color name are recorded in association with each other.

Next, the operation of reproducing the image data recorded on the memory card 13 will be described with reference to the flowchart of FIG.
When the image reproduction mode is set by the user's operation of the key input unit 9, it is determined in step S21 whether or not the image data to be reproduced is selected by the user from the image data recorded on the memory card 13. . This determination is made based on whether or not an operation signal corresponding to image data selection has been sent from the key input unit 9.
If image data is selected, the process proceeds to step S22. If image data is not selected, the process remains in step S21 until it is selected.
In step S22, the selected image data is read from the memory card 13, and the read image data is expanded and displayed on the image display unit 10. Also here, it is assumed that an image as shown in FIG. 4 is displayed.

Next, the process proceeds to step S23, and it is determined whether or not color name display is designated. If the designation of color name display is performed, the process proceeds to step S24, and if not, the process remains in step S23 until it is performed.
Here, when the image is displayed, the user moves the pointer to a location where the user wants to know the color name by operating the cursor key. When the movement of the pointer is completed, that is, when the pointer is moved to a location where the name of the color is desired, the execution key is operated. When the execution key is operated, it is determined that the designation of color name display has been performed. Here, as shown in FIG. 4, it is assumed that the cursor is moved to the front side of the object 22 and the execution key is operated.

In step S24, the color name at the position where the color name display is designated, that is, the position of the black dot 24 is read out. Here, the color name is read by calculating the position data of the black point 24 and reading the color name recorded corresponding to the calculated position data. It should be noted that the color name of the central portion of the image or a predetermined position (a focused position when the image is photographed, a preset position designated by the user in advance, a plurality of predetermined positions, etc.) When only the color name is associated with the image data, the color name may be automatically read out without specifying the color name display.
Next, the process proceeds to step S 25, where the read color name is displayed on the image display unit 10, or the sound output unit 11 outputs the sound of the color name. Note that both image display and audio output may be performed. When a plurality of color names are recorded in association with the position data, the color names may be switched by the user's operation of the key input unit 9.
For example, when the name of the greenish blue color is notified as “Asagi color”, it may be switched to “Nado color” or “Turquoise blue” by operating the key input unit 9. Good.

Thus, when the image shooting process is started, a through image of the subject is displayed on the image display device 10, and when the shutter button is pressed, the still image shooting process is performed.
Then, the RGB value for each pixel of the imaged image data and the position data where the pixel is located in the image are acquired, and the corresponding color name is searched for each pixel from the acquired RGB value. Then, the retrieved color name and position data are recorded in association with the captured image data. The color name and the position data are recorded in the memory card 13 in association with each other.

  When the image reproduction mode is set and the recorded image data is selected, an image of the selected image data is displayed on the image display unit 10. Then, the user looks at the image, operates the key input unit 9, puts the pointer on the part for which the name of the color is desired, and presses the execution key. Then, it is determined that the color name display is designated, the position data of the position of the combined pointer is calculated, the color corresponding to the position data and recorded in association with the selected image data The name is read out and displayed on the image display unit 10.

As described above, in the second embodiment, since the color name is searched and recorded by the color information of the acquired image, even if the color is not known by reproducing the recorded image, The user can easily know the name of the color.
It is also convenient when you want to buy the same paint or fabric as the colors shown in the image.
In addition, even visually impaired persons can easily recognize how many of these colors are useful in daily life.
Since the color name and the image data are recorded in association with each other, it is not necessary to search for the color name when reproducing the image data.

In the above embodiment, the image data is acquired by imaging with the CCD 2. However, the present invention is not limited to this, and the image data may be acquired from the outside such as the memory card 13 or the communication cable.
Further, the image recording apparatus in the second embodiment is not limited to the above embodiment, and may be a mobile phone, a PDA, a digital video camera, a personal computer, etc. Any device can be used.

[Modification]
The following modes are also possible as modifications of the first embodiment and the second embodiment.
When the color name is displayed on the image display unit 10 in the first embodiment and the second embodiment, as shown in FIG. 7A, it is displayed at a predetermined position in the image such as the upper right of the image. You may do it. Thereby, since the color name is always displayed at a predetermined location, the display of the color name can be made easier to see.
Further, as shown in FIG. 7B, the position may be displayed at a position in the image determined based on the position designated by the pointer or the position data corresponding to the color name. Thereby, it can be easily understood which part of the color the color name indicates.

Further, the pointer is moved by operating the cursor of the key input unit 9 and the color name at the position of the pointer when the execution key is pressed is displayed. However, the color name of the part touched by the touch panel or the like is displayed. May be displayed. This simplifies the user's operation of moving the cursor and pressing the execution key.
Further, a color name display mode may be provided so that the color name of the portion where the pointer is located is always displayed. In this case, the displayed color name changes without pressing the execution key and when the pointer moves. Thereby, the user's operation is reduced, and the color of the image can be easily recognized.

  In addition, the RGB value of the pixel of the part specified by the pointer is acquired. However, the RGB value of the average value of the area is acquired by specifying the area where the color name is desired instead of the pixel unit. It may be. Moreover, you may make it acquire the average value of the RGB value of the whole designated object. For example, as shown in FIG. 4, if the black point 24 of the object 22 is designated by the pointer, the average value of the RGB values of the pixels of the object 22 may be acquired. Thereby, even when the color of a certain region or object is partially different due to light adjustment, the color of the region or the entire object can be recognized.

  Alternatively, the type of the light source of light may be determined from the color of the image, and color correction corresponding to the RGB value may be retrieved after performing color correction to eliminate the influence of the light source color. Alternatively, a color name table may be recorded for each light source without performing color correction, and after determining the light source of light, the color name may be searched using the color name table corresponding to the light source. This is because if the light source is different (sunlight, fluorescence), the same color will change slightly. Thereby, the original color can be displayed without being influenced by the light source.

  If a plurality of color names, JIS standard “Z8102 object color name”, “common color name”, etc. are recorded for the RGB values, the color name display can be performed by operating the key input unit 9. However, it may be displayed so that it is automatically switched at intervals of a fixed time. For example, in the case of greenish blue, the color name is displayed as “Asagi Color”, and after a certain time elapses, it is displayed as “Nado Color” and after a certain time elapses “Turquoise Blue”. Good.

  Furthermore, at the time of displaying a through image, an RGB value or the like of a designated position or region or a central position of the image may be acquired to search for a color name and display the color name. In this case, any device that can image a subject may be used.
