Description

  The present invention relates to an imaging apparatus such as a digital camera, and more particularly to an imaging apparatus having a function of marking a point of interest at the time of shooting, and a mark creation method and program used in the imaging apparatus.

  Generally, in a digital camera, an image of a subject that is currently being photographed is displayed as a through image on a screen provided on the back of the camera body, and the user (photographer) can view the screen at any time while viewing the screen. A photographed image can be obtained by depressing the shutter key.

  Here, if the image is a subject photographed relatively close to the subject or an image photographed by enlarging using the zoom function, it is possible to know where the photographed image was focused. However, if the focal length of the lens is insufficient, or if the image was taken without sufficient zooming in due to reasons such as not being able to release the high-speed shutter, the area occupied by the point of interest in the captured image is small. Therefore, it is not possible to know where the image was taken after paying attention.

  The same applies to images that are normally captured, and depending on the composition of the subject, it may be difficult for the photographer himself or herself to know where the image was captured with attention.

  As a method for solving such a problem, when a photographed image is printed, a method in which a user performs marking on the printed material using a pen or the like is considered. There is a problem that it takes a lot of time and makes the printed matter dirty.

For example, in the case of a digital camera having a touch panel as disclosed in Patent Document 1, it is possible to mark a portion touched by a user with a finger during shooting. However, it cannot be applied to a digital camera that does not have a touch panel, and installing a touch panel only for marking is problematic in terms of cost.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing an external configuration when a digital camera is taken as an example of an imaging apparatus according to an embodiment of the present invention. FIG. 1 (a) is mainly a front configuration, and FIG. It is a perspective view which shows the structure of a back surface.

  This digital camera 1 has a photographing lens 3, a self-timer lamp 4, an optical viewfinder window 5, a strobe light emitting unit 6, a microphone unit 7, and the like on the front surface of a substantially rectangular thin plate-like camera body 2. ) A power key 8 and a shutter key 9 are provided on the right end side. The power key 8 is a key operated every time the power is turned on / off, and the shutter key 9 is a key for instructing a photographing timing at the time of photographing.

  Also, on the back of the digital camera 1, a shooting mode (R) key 10, a playback mode (P) key 11, an optical viewfinder 12, a speaker unit 13, a macro key 14, a strobe key 15, a menu (MENU) key 16, a ring A key 17, a set (SET) key 18, a display unit 19, and the like are provided.

  The shooting mode key 10 is operated automatically from the power-off state to automatically turn on the power and shift to the still image shooting mode. On the other hand, by repeatedly operating from the power-on state, the still image mode and the moving image mode are switched. Set cyclically. The still image mode is a mode for photographing a still image.

  The shutter key 9 is commonly used for these photographing modes. That is, in the still image mode, a still image is taken at the timing when the shutter key 9 is pressed. In the moving image mode, shooting of a moving image is started at a timing when the shutter key 9 is pressed, and shooting of the moving image is ended when the shutter key 9 is pressed again.

  When the playback mode key 11 is operated from the power-off state, the playback mode key 11 is automatically turned on to enter the playback mode. The optical viewfinder 12 is used for optically confirming a subject to be photographed by a user during photographing. The speaker unit 13 is used during audio reproduction.

  The macro key 14 is operated when switching between normal shooting and macro shooting in the still image shooting mode. The strobe key 15 is operated when switching the light emission mode of the strobe light emitting unit 6. The menu key 16 is operated when selecting various menu items. The ring key 17 is integrally formed with item selection keys in the up, down, left, and right directions, and the set key 18 located in the center of the ring key 17 sets the item selected at that time. To operate.

  The display unit 19 is composed of a color liquid crystal panel with a backlight, and displays a through image on the monitor as an electronic viewfinder in the photographing mode, and reproduces and displays the selected image and the like in the reproduction mode.

  Further, the digital camera 1 is provided with an optical zoom function, and the enlargement ratio of the image can be changed by physically changing the focal length by operating the zoom keys 20a and 20b. Of the zoom keys 20a and 20b, one zoom key 20a is for the telephoto end and is used when the zoom magnification is changed to the telephoto side. The other zoom key 20b is for the wide end and is used when the zoom magnification is changed to the wide angle side.

  Although not shown, the digital camera 1 has a memory card slot for attaching / detaching a memory card used as a recording medium, a serial interface connector for connecting to an external personal computer, etc., for example, USB (Universal). Serial Bus) connector and the like are provided.

  FIG. 2 is a block diagram showing an electronic circuit configuration of the digital camera 1.

  In the digital camera 1, a lens optical system 22 including a focus lens and a zoom lens (not shown) constituting the photographing lens 3 is provided so as to be movable within a predetermined range in the optical axis direction by driving a motor 21. A CCD (charge coupled device) 23, which is an image sensor, is disposed behind the optical axis. The CCD 23 receives light from each part of the subject input through the photographing lens 3 and outputs an electrical signal corresponding to the intensity of the light.

  In the recording mode, which is the basic mode, the CCD 23 is scanned and driven by a timing generator (TG) 24 and a driver 25, and outputs a photoelectric conversion output corresponding to a light image formed at regular intervals for one screen. The photoelectric conversion output of the CCD 23 is appropriately gain-adjusted for each primary color component of RGB in the state of an analog value signal, sampled and held by the sample hold circuit 26, and converted into digital data by the A / D converter 27. The

  Then, in the color process circuit 28, image processing including pixel interpolation processing and γ correction processing is performed to generate a digital luminance signal Y and color difference signals U and V (Cb, Cr), and DMA (Direct Memory Access). ) Output to the controller 29.

  The DMA controller 29 once uses the luminance signal Y and the color difference signals U and V output from the color process circuit 28 by using the composite synchronization signal, the memory write enable signal, and the clock signal from the color process circuit 28 once. And the DMA transfer to the DRAM 31 used as the buffer memory via the DRAM interface (I / F) 30.

  The control unit 32 controls the entire digital camera 1 and is constituted by a microcomputer including a CPU, a ROM storing an operation program executed by the CPU, a RAM used as a work memory, and the like. .

  After the DMA transfer of the luminance and color difference signals to the DRAM 31, the control unit 32 reads the luminance and color difference signals from the DRAM 31 via the DRAM interface 30 and writes them to the VRAM 34 via the VRAM controller 33.

  The digital video encoder 35 periodically reads the luminance and color difference signals from the VRAM 34 via the VRAM controller 33, generates a video signal based on these data, and outputs the video signal to the display unit 19.

  As described above, the display unit 19 functions as a monitor display unit (electronic finder) at the time of shooting. By performing display based on the video signal from the digital video encoder 35, the display unit 19 captures from the VRAM controller 33 at that time. An image based on the image information is displayed in real time.

  As described above, when the image at that time is displayed in real time as the monitor image on the display unit 19, for example, when the shutter key 9 is pressed at a timing at which still image shooting is desired, a trigger signal is generated.

  In response to the trigger signal, the control unit 32 immediately stops the path from the CCD 23 to the DRAM 31 immediately after the DMA transfer of the luminance and color difference signals for one screen captured from the CCD 23 to the DRAM 31 is completed. , Transition to the record storage state.

  In this recording and storage state, the control unit 32 outputs the luminance and color difference signals for one frame written in the DRAM 31 to 8 pixels × 8 pixels for each of Y, Cb, and Cr components via the DRAM interface 30. The data is read out in units called basic blocks and written in a JPEG (Joint Photographic Coding Experts Group) circuit 37. The JPEG circuit 37 uses an ADCT (Adaptive Discrete Cosine Transform) and an entropy coding system. Data compression is performed by processing such as conversion.

  The obtained code data is read out from the JPEG circuit 37 as a data file of one image and written in the recording memory 38. The memory 38 includes a memory card that is detachably mounted as a recording medium in addition to an internal memory such as a flash memory built in the main body in advance. With the compression processing of the luminance and color difference signals for one frame and the completion of writing all the compressed data to the memory 38, the control unit 32 activates the path from the CCD 23 to the DRAM 31 again.

  The control unit 32 is further connected with an audio processing unit 39, a USB interface (I / F) 40, and a strobe driving unit 41.

  The sound processing unit 39 includes a sound source circuit such as a PCM sound source, digitizes a sound signal input from the microphone unit (MIC) 7 during sound recording, and performs a predetermined data file format such as MP3 (MPEG-1 audio layer). 3) Data compression is performed in accordance with the standard to create an audio data file and send it to the memory 38. On the other hand, when reproducing the audio, the audio data file read from the memory 38 is uncompressed and converted into an analog signal. The sound is output through a speaker unit (SP) 13 provided on the back side.

  The USB interface 40 performs communication control when image data and other information are transmitted / received to / from another information terminal device such as a personal computer connected by wire via a USB connector. The strobe drive unit 41 charges a strobe capacitor (not shown) at the time of shooting, and then drives the strobe light emitting unit 6 to flash based on control from the control unit 32.

  In addition to the shutter key 9 described above, the key input unit 36 includes a power key 8, a shooting mode key 10, a playback mode key 11, a macro key 14, a strobe key 15, a menu key 16, a ring key 17, and a set key. 18, zoom keys 20 a and 20 b and the like, and signals accompanying these key operations are sent directly to the control unit 32.

  Further, when shooting a moving image instead of a still image, when the shutter key 9 is pressed, the captured moving image is compressed by the JPEG circuit 37 using a technique such as motion-JPEG and recorded in the memory 38. . When the shutter key 9 is operated again, the recording of the moving image data is finished.

  On the other hand, in the playback mode which is the basic mode, the control unit 32 selectively reads out the image data recorded in the memory 38 and is compressed by a procedure completely opposite to the procedure of data compression in the recording mode by the JPEG circuit 37. Decompress image data. The decompressed image data is held in the DRAM 31 via the DRAM interface 30, and then the content held in the DRAM 31 is stored in the VRAM 34 via the VRAM controller 33. The image data is periodically read out from the VRAM 34. A video signal is generated and reproduced and output by the display unit 19.

  If the selected image data is not a still image but a moving image, the multiple frames of still image data that make up the moving image data are played back and displayed sequentially in chronological order, and all the still image data is played back. For example, the top still image data is displayed until the next playback instruction is given.

  In addition, the digital camera 1 has a camera shake correction function. By moving a part of the lens optical system 22 or the CCD 23 in the direction opposite to the moving direction of the camera body 2 detected by the gyro sensor 42, an image forming point is obtained. Correct the deviation. The gyro sensor 42 includes, for example, a vibration type that detects an angular velocity. However, since the principle and configuration thereof are known, detailed description thereof is omitted here. As for the correction method, in addition to the optical type that adjusts and corrects the optical mechanism at the time of shooting, there is an electronic type that processes and corrects the captured image data, and this is also a general method. Detailed description will be omitted.

  Here, in the present embodiment, the gyro sensor 42 generally used in the camera shake correction is used, and the user (photographer) in the marked shooting mode uses the camera body of the digital camera 1 as shown in FIG. It is configured to detect a movement trajectory when 2 is moved. The “marked shooting mode” is a mode for marking a portion that is noticed by the user during shooting. This marked shooting mode can be arbitrarily set by the user through a mode setting screen 50 as shown in FIG.

  That is, the mode setting screen 50 is provided with check items 51 and 52 for selecting “normal shooting mode” or “marked shooting mode”, and the check item 52 is checked by operating a cursor key or the like. Thus, the “marking shooting mode” is set. At that time, by checking the check item 53 together, it is possible to process a peripheral image other than the marked part in the photographed image. The mode setting screen 50 is displayed on the display unit 19 by pressing the menu key 16 in the shooting mode.

Hereinafter, the image processing in the marked shooting mode will be described.
Note that the processes shown in the following flowcharts are executed when the control unit 32, which is a microcomputer, reads a program.

  FIG. 5 is a flowchart showing the shooting process of the digital camera 1 in the embodiment, and shows a process when the shooting mode of the still image is set by operating the shooting mode key 10.

  First, it is determined whether or not “marked shooting mode” is set (step A10). When it is not “marked shooting mode”, that is, when “normal shooting mode” is set in the check item 51 of the mode setting screen 50 shown in FIG. 4 (No in step A10), normal shooting processing is performed. Is executed. In a normal photographing process, the subject image data obtained through the CCD 23 as an image sensor is displayed on the display unit 19 as a through image. Then, at the timing when the user depresses the shutter key 9, the image data obtained at that time is captured as a photographed image, which is compressed by a predetermined method and recorded and stored in the memory 38.

  On the other hand, if the “marked shooting mode” is set in the check item 52 of the mode setting screen 50 (Yes in step A10), the user's attention is marked in the following procedure. .

  That is, the control unit 32 first acquires an image of the subject that is currently being photographed by the CCD 23 and displays it on the display unit 19 as a through image on the monitor 19 (step A11). Here, when the user presses the shutter key 9 halfway (Yes in Step A12), the control unit 32 determines that the marking operation by the user has been started, and the movement information of the camera body 2 detected by the gyro sensor 42 ( Based on the movement direction and movement amount), the movement locus of the camera body 2 is measured (step A13).

  When the half-pressed state of the shutter key 9 is released (Yes in Step A14), the control unit 32 determines that the marking operation by the user has been completed, and the movement locus of the camera body 2 obtained up to this point. Is shaped into an appropriate shape as a mark (step A15), and a mark is created based on the shaped movement trajectory and displayed on the through image (step A16).

6 and 7 show the situation at this time.
Now, for example, when photographing a distant view, it is assumed that there is a building 60 that is noticed by the user in the view. In the figure, 61 is a monitor visual field, that is, a monitor screen of the display unit 19, and 62 is a pointer provided at the center position of the monitor screen 61.

  In such a case, first, as shown in FIG. 6, the shutter key 9 is half-pressed with the camera body 2 held so that the pointer 61 on the monitor screen 61 comes near the building 60. Thereby, marking is started from the position of the pointer 61 at that time, and when the camera body 2 is moved by the pointer 61 so as to surround the building 60 as shown in FIG. Measured.

  When the halfway pressing of the shutter key 9 is released after the marking operation is completed, a mark 64 is created based on the movement trajectory 63 obtained up to that point and displayed at the corresponding position in the through image. In this case, even if the movement trajectory 63 is distorted, it is shaped into an appropriate shape as a mark and is visualized.

  That is, as shown in FIG. 8A, if the shape drawn by the movement locus 63 is close to a circle, a mark 64 shaped into a circle is displayed. Also, as shown in FIG. 8B, if the shape drawn by the movement trajectory 63 is close to a rectangle, a mark 64 shaped into a rectangle is displayed.

  Returning to FIG. 5, after the mark is displayed, when the user presses the shutter key 9 again (Yes in Step A <b> 17), the control unit 32 executes a shooting process to capture the image of the subject currently displayed on the monitor. (Step A18).

  When the digital camera 1 has an AF (automatic focusing) function, the shutter key 9 is first half-pressed in step A12 and the shutter key 9 is pressed again in step A17. The marking process is performed when the shutter key 9 is half-pressed in step A12, the AF process is performed when the shutter key 9 is half-pressed in step A17, and the photographing process is performed when the shutter key 9 is fully pressed. And

  If the processing of the peripheral image is specified by the check item 53 on the mode setting screen 50 shown in FIG. 4 (Yes in step A19), the control unit 32 increases the brightness of the peripheral image outside the mark, Alternatively, after performing predetermined processing such as monochrome (step A20), the mark is combined with the captured image obtained at that time and recorded in the memory 38 (step A21). Note that the photographed image and the mark may be recorded in association with different areas, and the two may be combined according to a specific instruction operation during reproduction or printing.

9 to 11 show the situation at this time.
When the camera body 2 of the digital camera 1 is moved after the mark is displayed, the mark 64 also moves in accordance with the movement of the camera body 2 and is always displayed at the position of the building 60. The movement control of the mark 64 is also performed based on the movement information of the camera body 2 detected by the gyro sensor 42.

  Here, as shown in FIG. 9, when the user determines the composition and presses the shutter key 9, the image of the subject currently displayed on the monitor screen 61 is recorded as a captured image together with the mark 64.

  FIG. 10 is a diagram illustrating an example of a photographed image with a mark, and a mark 64 is added to the building 60 that the user has focused on. In this case, if the processing of the peripheral image is designated, the image quality of the peripheral image outside the mark 64 is changed as shown in FIG. 11, and a captured image highlighting the building 60 in the mark 64 is obtained.

  In this way, it is possible to easily shoot a place where the user is paying attention when shooting. Accordingly, when the photographed image is viewed later, it is possible to easily determine from the mark which part is the photographed image.

  In addition, since the gyro sensor 42 mounted in advance for camera shake correction is used to detect and mark the movement trajectory of the camera body 2, no special equipment dedicated to marking such as a touch panel is required. Can be realized at low cost.

  In the above embodiment, the shutter key 9 is used for the marking operation in step A12. However, a specific key may be provided for the marking operation and the marking process may be performed by pressing the key.

  Further, when the shutter key 9 is used for the marking operation in step A12, it is also possible to perform the AF process at the same time as the marking process and perform the photographing while focusing on the marked part. In this case, AF is not released when the half-press of the shutter key 9 is released in step A14, and the photographing process is executed at the timing when the shutter key 9 is pressed again in step A17.

  In the above embodiment, the digital camera has been described. However, the present invention is not limited to the digital camera of the present invention, and may be an electronic device having an imaging function such as a mobile phone with a camera or a PDA (Personal Digital Assistant). It can be applied to all of them.
