JP 2005-269605 A

  In Patent Document 1, a main subject can be selected after shooting, but it is impossible to know whether a desired subject is captured at an angle of view before shooting.

  The present invention has been made in view of such problems, and it is an object of the present invention to automatically identify a subject image to be photographed and to encourage a photographer to photograph.

  An imaging apparatus according to the present invention includes an instruction unit that accepts a user input operation, an imaging element, an imaging lens that forms a subject image on the imaging element, and digital image data obtained continuously from the imaging element. A conversion unit for converting the image into the image, a display unit for displaying a subject image based on image data continuously output from the conversion unit, and an image for recording from the conversion unit in response to a shooting instruction being input to the instruction unit. And a recording unit that acquires and records an original image that is data.

  This image capturing apparatus collates a registration unit for registering information on a desired subject image with image data obtained continuously and information on the desired subject image in the registration unit, whereby image data of the desired subject image is obtained. A determination unit that determines whether or not the image data of the desired subject image is obtained, and an extraction unit that extracts the desired subject image from the image data in response to determining that the image data of the desired subject image is obtained. The instruction unit receives an input of a shooting instruction after the extracted subject image is displayed on the display unit.

  According to the present invention, the image data of the desired subject image is collated with the image data of the subject image (so-called through image) continuously obtained from the photographing element before the start of photographing, and information on the desired subject image. If this image data is obtained, the subject image is extracted from the image data and displayed. The user can confirm that the image data of the desired subject image is obtained by looking at this. If a desired subject image can be confirmed, a shooting instruction can be input and image data of the desired subject can be recorded by fully pressing the release button or touching the displayed desired subject image. it can.

  In the present invention, unlike the prior art, the user can visually confirm whether or not image data of a desired subject has been obtained before shooting, and arbitrarily determine whether or not to record image data according to the confirmation result. it can.

  The registration unit acquires and registers reference image data from the conversion unit, analyzes the color temperature distribution based on the reference image data, and corrects the color of the original image based on the color temperature distribution; The recording unit may record a corrected original image that is an original image whose color has been corrected by the correction unit in response to a shooting instruction.

  The correction unit may correct the reference image data based on the color temperature distribution, and the display unit may display the reference image data corrected by the correction unit.

  In this way, it is easy to create a color correction image, and it is expected that the color correction of the actually recorded original image is in line with the user's intention.

  The recording unit may record the uncorrected original image, which is an original image whose color has not been corrected by the correcting unit, and the corrected original image in association with the shooting instruction.

  In this way, the user can arbitrarily select and use either the uncorrected original image or the corrected original image.

  The recording unit may record the both of the uncorrected original image and the corrected original image in association with each other by assigning a common character to at least a part of the file name of the uncorrected original image and the corrected original image, or storing them in the same folder.

  The display unit emphasizes the subject image extraction area by applying blinking, inversion, frame enclosing, and other specific display effects to the subject image extraction area among a plurality of predetermined areas that divide the original image. The instruction unit may accept the designation of the subject image based on the designation of the subject image extraction area.

  If the subject image extraction area is designated, the subject image can be easily designated even in a scene where it is difficult to designate an operation such as underwater.

  When the first designation of the subject image is made from the instruction unit, the display unit enlarges and displays the subject image extraction area, and the recording unit designates the second subject image from the instruction unit within a predetermined time. If it is, the recording of the original image may be started.

  In this way, it is easy to visually confirm whether the extracted subject image is actually the subject image intended by the user, and it is also easy to give a subsequent shooting instruction.

  The image processing apparatus further includes a trimming unit that trims the extracted subject image extraction area from the image data, and the recording unit serves as a trimming source of the subject image extraction area. It may be recorded in association with the original image.

  This makes it easier to recall later what the subject image was intended to be taken.

  The recording unit starts recording the original image continuously when the second designation of the subject image is started from the instruction unit, and continuously when the third designation of the subject image is given from the instruction unit. The recording of the original image may be finished.

  When shooting fast-moving fish or athletes, it may not be possible to shoot at a good angle once at a time, so it is preferable to start and end continuous shooting automatically by specifying a subject image.

  The display unit displays the original images continuously recorded in the recording unit on the same screen and displays a selection unit that selects a desired original image based on a user operation among the original images displayed side by side on the same screen. Further, the display unit highlights the original image selected by the selection unit by adding blinking, inversion, frame enclosing, and other specific display effects, and the recording unit displays the original image selected by the selection unit. Should be recorded.

  In this way, it is possible to easily select and record only the images that the user wants to leave among the continuously shot images.

  It is preferable that the display unit emphasizes and displays an image including a subject image and having a large subject image area among the continuously recorded original images.

  This makes it easy to select and record a large subject image.

  The imaging method according to the present invention obtains image data of a desired subject image by registering information relating to the desired subject image, and collating continuously obtained image data with information relating to the desired subject image. Determining whether the image data of the desired subject image has been obtained, extracting the desired subject image from the image data in response to determining that the image data of the desired subject image has been obtained, and extracting the extracted subject image A step of displaying, and a step of recording image data by receiving designation of the displayed subject image.

  According to the present invention, the image data of the desired subject image is collated with the image data of the subject image (so-called through image) continuously obtained from the photographing element before the start of photographing, and information on the desired subject image. If this image data is obtained, the subject image is extracted from the image data and displayed. The user can confirm that the image data of the desired subject image is obtained by looking at this. If a desired subject image can be confirmed, a shooting instruction can be input and image data of the desired subject can be recorded by fully pressing the release button or touching the displayed desired subject image. it can.

  In the present invention, unlike the prior art, the user can visually confirm whether or not image data of a desired subject has been obtained before shooting, and arbitrarily determine whether or not to record image data according to the confirmation result. it can.

  FIG. 1 is a block diagram of a camera according to a preferred embodiment of the present invention.

  A lens motor is connected to the imaging lens 10. An iris motor is connected to the diaphragm 31. These motors are stepping motors, which are controlled in operation by drive pulses transmitted from motor drivers 30 and 32 connected to the CPU 33, and perform photographing preparation processing in response to half-pressing of the release button 12.

  The lens motor moves the zoom lens of the imaging lens 10 to the wide side or the tele side in conjunction with the operation of the zoom operation button. Further, the focus lens (not shown) of the imaging lens 10 is moved in accordance with zooming magnification of the zoom lens, etc., and focus adjustment is performed so that the photographing conditions are optimized. The iris motor driver 32 operates the diaphragm 31 to perform exposure adjustment.

  Behind the imaging lens 10 is a CCD 36 that photoelectrically converts the subject image formed by the imaging lens 10. A timing generator (TG) 37 controlled by the CPU 33 is connected to the CCD 36, and the shutter speed of the electronic shutter is determined by a timing signal (clock pulse) input from the TG 37.

  The imaging signal output from the CCD 36 is input to a correlated double sampling circuit (CDS) 38 and continuously output as R, G, and B image data that accurately corresponds to the accumulated charge amount of each cell of the CCD 36. . The image data output from the CDS 38 is amplified by an amplifier (AMP) 39 and converted into digital image data by an A / D converter (A / D) 40.

  The image input controller 41 is connected to the CPU 33 via the bus 42, and controls the CCD 36, CDS 38, AMP 39, and A / D 40 in accordance with a control command from the CPU 33. The image data output from the A / D 40 is temporarily recorded in the SDRAM 43.

  The color correction unit 45 reads the image data from the SDRAM 43, corrects the color absorption that varies depending on the water depth and the distance to the subject, and stores the corrected image data in the SDRAM 43. This corrects the bluish subject to a state close to true natural color development. The reason why the subject turns blue is that, of visible light emitted from the sun, red having a long wavelength is absorbed by water at a depth of about 2 meters, whereas blue is not absorbed.

  The image signal processing circuit 44 reads the image data from the SDRAM 43, performs various image processing such as gradation conversion, white balance correction, and γ correction processing, and converts the image data into the luminance signal Y and the color difference signals Cr and Cb. Convert.

  The VRAM 46 is a memory for continuously outputting a through image for angle-of-view confirmation to an image display device (LCD) 22a on which the touch panel 22b is stacked, and stores image data that has passed through the image signal processing circuit 44. In the VRAM 46, two frames of memories 46A and 46B are secured so that image data can be written and read in parallel. The image data stored in the VRAM 46 is converted into an analog composite signal by the video encoder 47 and displayed as a through image on the LCD 22a.

  The compression / decompression processing circuit 48 performs image compression on the YC converted image data in a predetermined compression format (for example, JPEG format). The compressed image data is stored in the recording medium 50 via the media controller 49.

  In addition to the release button 12 and the operation unit 23 described above, an EEPROM 51 is connected to the CPU 33. The EEPROM 51 stores various control programs and setting information. The CPU 33 reads these pieces of information from the EEPROM 51 to the SDRAM 43, which is a working memory, and executes various processes.

  The bus 42 detects an exposure amount, that is, whether the shutter speed of the electronic shutter and the aperture value of the aperture 31 are appropriate for shooting, and detects whether the white balance is appropriate for shooting. 52 and an AF detection circuit 53 that detects whether or not the focus adjustment of the imaging lens 10 is appropriate for shooting.

  The AE / AWB detection circuit 52 detects the appropriateness of the exposure amount and the white balance based on the integrated value of the luminance signal Y of the YC converted image data and the color difference signals Cr and Cb, and sends the detection result to the CPU 33. Send. The CPU 33 controls the operations of the imaging lens 10, the diaphragm 31, and the CCD 36 based on the detection result transmitted from the AE / AWB detection circuit 52.

  The AF detection circuit 53 calculates a focus evaluation value representing the sharpness of the image from the image data digitized by the A / D 40 and transmits the calculation result to the CPU 33. The focus evaluation value is obtained by performing contour extraction processing on a specific area of the image, for example, image data of the central portion of the shooting angle of view by using a band pass filter or the like, and extracting the contour signal and image data of the central portion. Can be obtained by integrating the luminance values. Here, the larger the focus evaluation value is, the more high-frequency components are in that portion, indicating that the portion is in focus.

  The CPU 33 determines the search range for the focus lens focus position from the position of the zoom lens at the time of shooting preparation processing associated with half-pressing of the release button 12, and controls the operation of the imaging lens 10 via the motor driver 30. Then, within the determined search range, the focus lens is moved, for example, from the near point side to the far point side, and the focus evaluation values sequentially transmitted from the AF detection circuit 53 at that time are compared, thereby obtaining a focus evaluation value. The focus lens is stopped at the position where is the maximum, that is, at the in-focus position.

  FIG. 2 is a flowchart showing the flow of registration processing executed by the camera.

  In S1, fish information including information about various subjects such as data indicating a desired subject image such as fish (typically image data itself, but may also include feature amount information of the subject image) and fish description. The recorded recording medium 50 is inserted into a predetermined media slot, and the media controller 49 recognizes the recording medium 50.

  The acquisition source of the fish information is not limited to the recording medium 50, but may be a CD-ROM, a personal computer, a Web site, or the like.

  In S2, the camera is switched to the playback mode (selecting the contact point of SW2-2 in FIG. 1).

  In S 3, the media controller 49 reads fish information from the recording medium 50 and stores it in the VRAM 46. The video encoder 47 sequentially converts the fish subject image included in each fish information into a composite signal and outputs the composite signal to the LCD 22a. By doing so, fish images are reproduced in sequence (see FIG. 3).

  In S4, the user inputs a signal for determining the fish to be photographed from the touch panel 22b in response to the image of the fish to be photographed appearing on the image display device 22a. The CPU 33 repeatedly determines whether or not this signal has been input. If it is determined that the signal has been input, the process proceeds to S5, and if it has not been input, the process proceeds to S3.

  In FIG. 3, a signal for determining a fish to be photographed is input by touching the “yes” portion, and the process proceeds to S5. If the “No” part is touched, the process proceeds to S3, and the subject image of the next fish is displayed.

  In S5, the confirmed fish information is recorded in the EEPROM 51.

  FIG. 4 is a flowchart showing a flow of photographing processing executed by the camera.

  In S11, the camera is switched to the shooting mode (selecting the contact point of SW2-1 in FIG. 1). In response to this, the display of the through image on the LCD 22a starts.

  In S12, the angle of view is adjusted to the fish to be photographed. The CPU 33 extracts a fish video portion from the through image, and collates the extracted fish video portion with the fish subject image (or its feature amount) included in the fish information registered in the registration process. A method of collating and extracting the fish image portion and the registered subject image is arbitrary, and a known object recognition technique may be applied.

  In S13, half-pressing of the release button 12 is detected.

  In S14, it is determined whether or not the extracted fish image portion matches the registered fish subject image. If they match, the process proceeds to S15, and if they do not match, the process proceeds to S13.

  In S15, the extracted fish image is enlarged and displayed on the LCD 22a.

  In S16, the full press of the release button 12 is detected.

  In S <b> 17, the original image, which is recording image data acquired in response to detection of full release button 12, is recorded on the recording medium 50 as compressed still image data.

  According to this process, the user can easily know from the enlarged fish image that he / she caught the same type of fish as the fish he / she registered in advance because he / she wanted to shoot. In response to this, an instruction to record an image (full release button 12 pressed) can be started.

<Second Embodiment>
FIG. 5 is a flowchart showing a flow of photographing processing according to the second embodiment.

  In S21, the shooting mode is set. In response to this, the display of the through image on the LCD 22a starts.

  In S22, in response to half-pressing of the release button 12, extraction of the fish video portion is started.

  In S23, it is determined whether or not the extracted fish image portion matches the registered fish subject image. If they match, the process proceeds to S24, and if they do not match, the process proceeds to S22.

  In S24, the section including the extracted fish image portion is highlighted and displayed by a method such as blinking or inversion. As illustrated in FIG. 6, the screen is divided into four parts in advance, for example, vertically and horizontally, and the outer edge of each section is marked with a solid line so that each can be distinguished. In addition, the section including the extracted fish image portion is displayed in a blinking manner (FIG. 6A) or a reverse display of the background color (FIG. 6B) so that it can be easily identified visually.

  In S25, the touch panel 22b accepts a touch selection of a section including the highlighted fish image portion. That is, the touch selectable portion is larger than the fish image portion itself, and an accurate touch operation can be easily performed even when the photographer wears gloves or the desired fish moves quickly.

  In S26, when the touch panel 22b accepts the touch selection of the section including the fish image portion, the touched section is enlarged and displayed (FIG. 6C). This makes it easy to identify which section has been touched.

  In S <b> 27, it is determined whether or not a second touch is performed on the enlarged section within a predetermined time (for example, 0.5 seconds). If the second touch is made within the predetermined time, the process proceeds to S28, and if not, the process proceeds to S22. The second touch may be a double touch.

  In S28, the original image, which is the recording image data acquired in response to the second touch detection, is recorded on the recording medium 50 as compressed still image data. Data corresponding to the enlarged section may be trimmed from the recording image data, and both the entire image and the trimmed enlarged image may be recorded on the recording medium 50 in association with each other. In this way, it is easy to recall later what kind of subject image was taken for the purpose.

  In addition, if the second touch is made to the enlarged section within a predetermined time, continuous shooting is automatically started, and if the third touch is made to the enlarged section, it is automatically You may end the continuous shooting. This is effective when it is difficult to photograph in a good state such as when a fast-moving subject such as a fish faces sideways.

<Third Embodiment>
Color correction by the color correction unit 45 is performed as follows.

  FIG. 7 is a flowchart showing the flow of color correction processing.

  In S31, a dummy image serving as a reference indicating the color state in the current shooting situation such as underwater is shot. It is preferable not to include subjects such as fish in the dummy image.

  In S32, the output of the color components red R, green G, and blue B is extracted from the image data of the dummy image read from the VRAM 46, and the color distribution (distribution of B / G with respect to R / G) is calculated. And the color temperature (blueness) is estimated (see FIG. 9A).

  In S33, in response to the release button 12 being fully pressed, an original image (see FIG. 8A) that is still image data for recording is acquired and recorded.

  In S35, the playback mode is switched (the SW2-2 side in FIG. 1 is selected).

  In S <b> 36, the color correction unit 45 selects red R, green G, and blue B correction coefficients α, β, and γ stored in the EEPROM 51 based on the blueness estimation result obtained by analyzing the color distribution. Then, the output of red R, green G, and blue B of the original image is multiplied by coefficients α, β, and γ to obtain corrected image data with a natural hue as a whole (see FIG. 9B). Then, the LCD 22a reproduces the original image after the correction (see FIG. 8B). The color-corrected image data may be recorded in association with image data that has not been color-corrected according to a user instruction. Note that the correction coefficient may be selected manually.

  FIG. 10 is a flowchart showing another example of the flow of color correction processing.

  In S41, a dummy image is taken. It is not necessary to include a subject image such as a fish to be taken in the dummy image, but it is desirable to use a white or gray board as the subject image since it is used as a reference for color correction. This board may also be used as a message board for diving.

  In S42, the color distribution of the dummy image is analyzed and blueness is estimated.

  In S43, the playback mode is switched. The color correction unit 45 reproduces the image data by multiplying the outputs of the red R, green G, and blue B of the dummy image data by the coefficients α, β, and γ.

  In S44, recording still image data is acquired in response to the release button 12 being fully pressed. After S44, there is no need to perform the operation unless the release button 12 is fully pressed.

  In S45, the red R, green G, and blue B outputs of the still image data are multiplied by coefficients α, β, and γ, and the image data is reproduced. The color-corrected image data may be recorded in association with image data that has not been color-corrected according to a user instruction.

  In this way, unlike the correction process of FIG. 7, the state of correction of the dummy image can be confirmed before shooting.

<Fourth embodiment>
FIG. 11 shows an example of an original image and its image file name.

  For example, if a fish named “A” is photographed, the fish information includes the wide-angle original image as “KOU *** A” and the cropped enlarged image as “ZOOM *** A”. The two fishes are associated with each other by assigning a common fish name. Note that the original image and the enlarged image may be associated by storing them in the same folder.

  FIG. 12 conceptually shows the storage directory structure of the image file in the recording medium 50.

  A directory corresponding to the fish name “A” is created under the sub-directory “100_fuji” for classifying and storing still images in general, and the wide-angle original image “KOU *” before being multiplied by the correction coefficient is created in the hierarchy below it. ** A ”and an image (extracted image)“ ZOOM *** A ”obtained by trimming the enlarged image are stored. Furthermore, information related to fish such as registered fish images and fish names may be stored together under the directory “100_fuji”.

  By creating such a subdirectory for each original image, the original image and the extracted image can be associated with each other.

<Fifth Embodiment>
FIG. 13 shows an example of a multi-screen in which images taken continuously (continuous shooting) are reproduced on the same screen.

  In this screen, a plurality of original images are displayed in a tile at the same size. When a desired plurality of original images are selected by touching, the selected images are highlighted by blinking or reversing. Only the selected original image is recorded. In this way, only necessary images are left out of the continuously shot images.

  FIG. 14 is a flowchart showing the detailed flow of this process (selected image recording process).

  In S51, a plurality of original images are reproduced side by side on the same screen (FIG. 13).

  In S52, the original image is selected according to the user's touch operation.

  In S53, the area of the selected image is highlighted by blinking or reversing. In FIG. 13, images “3”, “4”, and “9” are selected and highlighted.

  In S54, the user is prompted to confirm whether or not to store the selected image in the same directory. If the user inputs confirmation of the storage of the selected image, the process proceeds to S55. If confirmation is not input, the process proceeds to S52.

  In S55, only the selected original image is recorded on the recording medium 50. The selected original image may be recorded in association with fish information that matches the original image or an enlarged image trimmed from the original image (FIG. 12).

  As shown in FIG. 15, the original image (FIG. 15A), the registered image and fish information (FIG. 15B), and only the registered image (FIG. 15C) are selected according to the user's selection. It may be switched and played back sequentially.

<Sixth Embodiment>
As shown in FIG. 16, in order to make it easier to preferentially record an image showing a larger fish, the fish having a larger size is emphasized preferentially and displayed on a multi-screen. The image may be touch-selected.

  FIG. 17 is a flowchart showing the flow of a photographing process according to the sixth embodiment.

  In S61, the mode is switched to the shooting mode.

  In S62, continuous shooting is automatically performed. As described above, continuous shooting starts by touching a section that is enlarged and displayed within a predetermined time, and ends by touching the section again.

  In S63, the area of the fish subject image included in each continuously shot image is calculated.

  In S64, a predetermined number (for example, the top three) is selected from the fish subject images having the largest area.

  In S65, all the original images are displayed in multiple on the same screen. In addition, the original image selected in S64 is highlighted with a frame or blinking (FIG. 16).

  In S66, a desired original image is touch-selected.

  In S67, the fish information including the touch-selected original image and the video that matches the original image is stored in the same folder.

  In this way, it is possible to easily select and record an image of a large subject image from among the images that have been continuously shot.

<Sixth Embodiment>
The “fish information” in the above embodiment is merely an example, and may be anything as long as it includes the subject image and other information related to the subject. Therefore, if the subject to be photographed is a person or an object, subject information including various information such as the image of the person or object and the name of the person or object may be registered instead of the fish information.

  When human face information is included in the subject information, the conventional face recognition technology is applied to collate the original image with the face information, and the face portion extracted from the through image and the registered face information are What is necessary is just to judge whether it corresponds.
