(Embodiment 1)
FIG. 1 is a diagram showing an embodiment of camera shake state display by a camera shake state notification method according to the present invention. In a camera having a camera shake detection function, one component of camera shake is monitored in time series. An example of graph display on the screen 5 (FIG. 4) is shown.
At the time of shooting, the photographer looks at the through image displayed on the monitor, places the desired subject 51 in the camera field of view, presses the shutter key 8 (FIG. 4) halfway, and when the autofocus is completed, confirms the composition and confirms the shutter key 8 Press fully. At the same time as the through image display from the start of photographing, the shake detection unit 31 (FIG. 5) detects the amount and direction of camera shake (the direction of camera shake), and one component of the camera shake components is graphed (step in FIG. 6). S3 to S5, steps T3 and T4 in FIG. 7, or step T6). A line graph (in the example of FIG. 1, a line graph of a pitch (PITCH) component) 56 is displayed in the graph display field 52. In the illustrated example, a line graph 56 is developed in time series from left to right, and when the range of the graph display field 52 is exceeded, the oldest one is deleted in order and a new camera shake amount is displayed (the line graph is displayed as a graph). If the range of the column 52 is exceeded, the graph appears to move from right to left on the monitor screen 5). The center line 53 of the graph display field 52 means camera shake 0 (zero). Note that the graph to be displayed is not limited to a line graph. For example, a wavy graph, a line graph, or a bar graph may be used, and the thickness and shape of the line may be changed.

  As described above, the upper and lower hand shake states that are most likely to cause blur are displayed in time series, so that the photographer can easily grasp the transition of the hand shake that tends to occur. The digital camera 100 can be consciously stabilized by, for example, holding the camera firmly so that the upper and lower camera shakes of the digital camera 100 do not occur immediately before. That is, instead of re-setting the camera every time there is a warning as in the case of Patent Document 1 described above, the digital camera 100 is spontaneously stabilized immediately before the shutter key 8 is pressed to prevent camera shake. Therefore, the photographer does not feel bothered as in the case of the technique of Patent Document 1.

Although only one component is displayed in the example of FIG. 1, as shown in FIG. 2, three components of the camera shake amount, that is, a pitch component, a yaw (YAW) component, and a roll (ROLL) component are displayed. As shown in FIG. 3, two components may be displayed.
Here, as shown in FIG. 8, when the horizontal direction of the camera 200 is the X axis, the vertical direction is the Y axis, and the axis that penetrates the camera from the front to the back is the Z axis, the pitch is centered on the Z axis. Y-direction movement (that is, left-right up-and-down movement), yaw is movement in the Z-direction around the Y-axis (that is, left-right back-and-forth movement), and roll is Y-centered around the X-axis It means directional movement (that is, vertical movement back and forth).

FIG. 2 is a diagram showing an example of a camera shake state display by the camera shake state notification method according to the present invention, and shows an example in which three components of camera shake are displayed in a graph on the monitor screen 5 in time series.
At the same time as the through image display from the start of shooting, the shake detection unit 31 detects the amount of camera shake and the orientation, and the three components (pitch component, yaw component, roll component) are each graphed by the graphing means. Then, the graphs are displayed in the graph display field 52 as line graphs 56, 57, and 58 having different colors. In the example shown in the figure, line graphs 56, 57, and 58 are developed in time series from left to right. When the range of the graph display column 52 is exceeded, the oldest one is deleted in order and a new camera shake amount is displayed.
In the example of FIG. 2, three line graphs are displayed in the same display column. However, a display column may be provided on the left side, the right side, or the upper side of the screen 5 and displayed separately (see FIG. 3). ). The position of the display column is not limited to the periphery. That is, a line graph may be displayed at a position that does not interfere with the subject. The graph to be displayed is not limited to a line graph. For example, a wavy graph, a line graph, or a bar graph may be used, and the thickness and shape of the line may be changed.

  In this way, the camera shake state is displayed in chronological order with the three components of up / down, left / right, and front / back, so that the photographer can easily grasp the transition and size of the top / bottom, left / right, front / rear camera shake. The digital camera 100 can be consciously stabilized without camera shake of the digital camera 100 occurring immediately before. Similarly to the example of FIG. 1, since the digital camera 100 can be voluntarily stabilized immediately before the shutter key 8 is pressed to prevent camera shake, the photographer can be as in the case of the technique of Patent Document 1. There is no annoyance.

FIG. 3 is a diagram showing an example of a camera shake state display by the camera shake state notification method according to the present invention, and shows an example in which two components of camera shake are displayed in a graph on the monitor screen 5 in time series.
At the same time as the through image display from the start of shooting, the shake detection unit 31 detects the amount and direction of camera shake, and the two components (pitch component and yaw component) are respectively graphed by the graphing means. A line graph 56 is displayed in the horizontal graph display field 52 and a line graph 57 is displayed in the vertical graph display field 53. In the illustrated example, a line graph 57 is developed in time series from the left to the right of the graph display field 52, and a line graph 56 is developed in time series from the top to the bottom of the graph display field 53. When the range of the graph display fields 52 and 53 is exceeded, the oldest ones are erased in order and a new camera shake amount is displayed. Each line graph is desirably displayed in a different color. The graph to be displayed is not limited to a line graph. For example, a wavy graph, a line graph, or a bar graph may be used, and the thickness and shape of the line may be changed.
In the example of FIG. 3, two line graphs are displayed in separate display fields, but may be displayed together in the same display field. The position of the display column is not limited to the periphery. That is, a line graph may be displayed at a position that does not interfere with the subject.

  In this way, the camera shake state is displayed in time series with two components of pitch and yaw that are likely to cause camera shake, so that the photographer can grasp the transition and size of camera shake that tends to occur. The digital camera 100 can be consciously stabilized without camera shake of the digital camera 100 occurring immediately before. As in the example of FIGS. 1 and 2, the digital camera 100 can be spontaneously stabilized immediately before the shutter key 8 is pressed to prevent camera shake. So you don't feel bothered.

  In the description of FIGS. 1 to 3, the case where the device capable of detecting the shake amount and the direction is used as the shake detection unit 31 (FIG. 5). However, the shake detection unit 31 (FIG. 5) is used as the shake detection unit 31 (FIG. 5). In the case of a simple device (or program) that can detect only the camera shake amount, the camera shake amount may be displayed in time series.

FIG. 4 is an external view of a digital camera as an embodiment of the camera according to the present invention. 4A is a front view of the digital camera 100, FIG. 4B is a configuration example of an imaging unit inside the camera, and FIG. 4C is a rear view.

FIG. 5 is a diagram showing an embodiment of the electronic circuit configuration of the digital camera 100 of FIG.
In FIG. 5, the digital camera 100 has an automatic focusing (autofocus (AF)) function in a photographing mode which is a basic mode, a motor 11 that moves a focusing position and an aperture position, and a lens optical that constitutes the photographing lens 2. System 12, CCD 13 as image sensor, timing generator (TG) 14, vertical driver 15, sample hold circuit (S / H) 16, A / D converter 17, color process circuit 18, DMA (Direct Memory Access) controller 19, DRAM interface (I / F) 20, DRAM 21, control unit 22, VRAM controller 23, VRAM 24, digital video encoder 25, display unit 26, JPEG circuit 27, memory card 28, built-in memory 29, key input unit 30, blur A detection unit 31 is provided. In FIG. 5, the lens optical system 12 to the color process circuit 18 correspond to an image pickup unit in the present invention.

In the monitoring state in the shooting mode, the focus position and the aperture position are moved by driving the motor (M) 11, and the imaging element is arranged behind the shooting optical axis of the optical system 12 constituting the shooting lens 1. The CCD 13 is scanned and driven by a timing generator (TG) 14 and a vertical driver 15, and outputs a photoelectric conversion output corresponding to a light image formed at regular intervals for one screen.
The CCD 13 is a solid-state imaging device that captures a two-dimensional image of a subject, and typically captures an image of several tens of frames per second. The imaging element is not limited to a CCD, and may be a solid-state imaging device such as a CMOS (Complementary Metal Oxide Semiconductor).

  The photoelectric conversion output is appropriately gain-adjusted for each primary color component of RGB in the state of an analog value signal, sampled and held by a sample hold circuit (S / H) 16, and digital data by an A / D converter 17. The color process circuit 18 performs color process processing including image interpolation processing and γ correction processing in the color process circuit 18 to generate a digital luminance signal Y and color difference signals Cb and Cr, and a DMA (Direct Memory Access) controller 19. Is output.

  The DMA controller 19 uses the luminance signal Y and the color difference signals Cb and Cr output from the color process circuit 18 once by using the composite synchronization signal, the memory write enable signal, and the clock signal from the color process circuit 18 once. DMA transfer is performed to the DRAM 21 used as a buffer memory via the interface (I / F) 20.

  The control unit 22 is used as a CPU, a program storage memory such as a flash memory in which an operation program executed by the CPU including processing for camera shake detection in the shooting mode as will be described later is fixed, and a work memory The digital camera 100 controls the entire digital camera 100. After the DMA transfer of the luminance and chrominance signals to the DRAM 21, the luminance and chrominance signals are transferred from the DRAM 21 via the DRMA interface 20. Read and write to the VRAM 24 via the VRAM controller 23.

The control unit 22 performs execution control such as calculation of a camera shake component from a camera shake (camera shake amount and orientation) detection value, time-series display of a camera shake state, and the like in a shooting mode.
For example, the camera shake components of the camera body (up / down, front / rear, left / right) are calculated based on the camera shake (shake amount and orientation) detection signal from the camera shake detection unit 31, and the calculated camera shake components are graphed to display the liquid crystal monitor screen 5. (See FIGS. 1 to 3).

  The control unit 22 also extracts a processing program and menu data corresponding to each mode stored in a program storage memory such as a flash memory in response to the status signal from the key input unit 30, and In addition to performing execution control of other functions, for example, execution of imaging and playback of recorded images, etc., display of a function selection menu at the time of function selection, selection function menu specified by cursor key 3 or the like and determination of image selection Control.

  The digital video encoder 25 periodically reads the luminance and color difference signals from the VRAM 24 via the VRAM controller 23, generates a video signal based on these data, and outputs the video signal to the display unit 26.

As described above, the display unit 26 functions as a monitor display unit (electronic finder) in the shooting mode. By performing display based on the video signal from the digital video encoder 25, the display unit 26 receives from the VRAM controller 23 at that time. An image based on the stored image information is displayed in real time.
In this way, in the display state of a so-called through image in which the image at that time is displayed in real time on the display unit 26 as a monitor image, the shutter key 8 (see FIG. When 4) is operated, a trigger signal (shooting instruction signal) is generated.

  In response to the trigger signal, the control unit 22 immediately stops the path from the CCD 13 to the DRAM 21 after the DMA transfer of the luminance and color difference signals for one screen captured from the CCD 13 to the DRAM 21 at that time. Transition to saved state.

In this stored recording state, the control unit 22 transmits the luminance and color difference signals for one frame written in the DRAM 21 through the DRAM interface 20 to each of Y, Cb, and Cr components of 8 pixels × 8 pixels horizontally. Are read in units called basic blocks and written into a JPEG (Joint Photograph Cording Experts Group) circuit 27. The JPEG circuit 27 uses ADCT (Adaptive Discrete Cosine Transform), a Huffman code which is an entropy coding system. Data compression is performed by processing such as conversion.
The obtained code data is read out from the JPEG circuit 27 as a data file of one image, and is recorded and stored in either the memory card 28 or the built-in memory 29 that is detachably mounted as a recording medium of the digital camera 100.
Then, along 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 card 28 or the built-in memory 29, the control unit 22 activates the path from the CCD 13 to the DRAM 21 again.

  In the playback mode, which is the basic mode, the control unit 22 selectively reads out the image data recorded in the memory card 28 or the built-in memory 29, and is completely opposite to the procedure in which the data is compressed in the image shooting mode by the JPEG circuit 27. The image data compressed in accordance with the procedure is expanded, the expanded image data is expanded and stored in the VRAM 24 via the VRAM controller 23, and then periodically read out from the VRAM 24. A signal is generated and reproduced by the display unit 26.

The JPEG circuit 27 supports a plurality of compression ratios, and a mode for storing data corresponding to the compression ratio includes a mode corresponding to a high resolution (generally called high definition, fine, normal, etc.) with a low compression ratio. There is a low-resolution (commonly called economy) mode with a high compression rate.
It also supports high to low pixel counts. For example, there are pixel sizes called SXGA (1600 × 1200), XGA (1024 × 786), SVGA (800 × 600), VGA (640 × 480) and the like.

The key input unit 30 includes the mode selection key 2, the cursor key 3, the set key 4, the shutter key 8, the power key 9, and the like described above, and signals associated with these key operations are directly sent to the control unit 22. .
The mode selection key 2 includes a slide key in the illustrated example, and performs selection of a shooting mode that is a basic mode and a moving image shooting mode that is a lower mode, and a playback mode and a moving image playback mode that is a lower mode thereof. Can do.
The cursor key 3 is normally used for a cursor movement operation performed when selecting a menu. The set key 4 is normally used when confirming the point result with the cursor key 3 or confirming the set value. When the set key 4 is pressed, the point result with the cursor key 3 is confirmed and the process designated by the cursor is started. Is done.
The shutter key 8 has a two-step pressing structure of half-pressing and full-pressing, and outputs a first trigger signal (in this case, an automatic focusing instruction signal) when half-pressed and released, and when fully pressed and released, as described above. A (second) trigger signal (imaging instruction signal) is output.
Note that selection of various shooting modes and playback modes such as movie shooting and movie playback may be performed by providing a dedicated key.

The shake detection unit 31 may use a known small azimuth and vibration detection device, and detects the shake (pitch, yaw, roll) of the top, bottom, left, and back of the digital camera 100 at the time of shooting and converts it into a digital signal. A camera shake (camera shake amount, camera shake direction) detection signal is sent to the control unit 22. As the azimuth and vibration detection device, for example, two or three angular velocity sensors / vibration gyros as described above can be used.
The shake detection unit 31 is configured as a camera shake calculation device including a small azimuth and vibration detection device and a one-chip microcomputer, and the calculated camera shake component information (pitch, yaw, roll information) of the camera body is controlled. 22 may be transmitted.
In addition, the shake detection unit 31 may be a small and inexpensive device that can detect only vibration (amount of camera shake).
In addition, the blur detection unit 31 is configured as a one-chip microcomputer that realizes a function of acquiring a difference between images in the comparison target area of the images before and after being captured in the DRAM 21 and calculating and calculating a shake amount in a cyclic manner. Alternatively, in place of the blur detection unit 31, a function of acquiring a difference between images in the comparison target area of the images before and after being captured in the DRAM 21, calculating a camera shake amount, and storing it cyclically is realized. The program to be stored may be stored in the program storage memory.

(Camera shake display operation)
FIG. 6 is a flowchart illustrating an example of a camera shake state notification operation of the digital camera. The processing shown below is basically explained by an example in which the control unit 22 executes in accordance with a program stored in advance in a program memory such as a flash memory, but it is not necessary to store all functions in the program memory. Alternatively, a part or all of them may be received via a network. Hereinafter, an example in which the present invention is applied to the digital camera 1 shown in FIGS. 4 and 5 will be described.

  In the shooting mode, the control unit 22 executes AE processing at a focal length corresponding to the zoom value at that time, obtains image data from the CCD 13, and achieves white balance corresponding to the color of the light source by automatic white balance (AWB) processing. As described above, after adjustment is performed by the color process circuit 18, the VRAM 24 is rewritten with video through image data obtained by thinning out image data from the CCD 13, and a through image is displayed on the display unit 26 (step S1).

  The shake detection unit 31 detects the up / down, left / right, and front / rear shakes (pitch, yaw, roll) of the digital camera 100 and sends detection signals (digital signals) to the control unit 22 at predetermined time intervals. Receives a camera shake detection signal output from the shake detector 31 (step S2) and displays a camera shake component to be displayed (pitch component in the display example of FIG. 1, pitch component, yaw component, and roll component in the display example of FIG. 2). In the example of FIG. 3, a pitch value and a yaw component are extracted to generate a graph value (step S3), and the generated graph value is stored in a graph value storage area (not shown) secured on the DRAM 21. It is stored cyclically as the latest value of the time series graph value. That is, when the graph value storage area is full, the storage area is shifted and the oldest value is deleted (step S4).

  Next, the control unit 22 applies the time series graph values stored in the graph value storage area to the digital video encoder 25 via the VRAM controller 23 to generate a video signal and output it to the display unit 26 to display the liquid crystal monitor screen. 5 is a time-series graph indicating a camera shake state (graph display column 52 in the display examples of FIGS. 1 and 2, pitch component in the graph display column 52 and yaw component in the graph display column 53) in the display example of FIG. (See FIGS. 1 to 3) (step S5).

  The control unit 22 checks the signal from the key input unit 30, and proceeds to step S7 if the shutter key 8 is half-pressed, and returns to step S1 if not pressed (step S6).

  Next, the control unit 22 performs AF (automatic focusing) processing so as to focus on a predetermined focus area, locks the focusing position when focusing is completed (step S7), and the shutter key 8 is fully pressed. It is checked whether or not an operation has been performed. If the shutter key 8 has been fully pressed, the process proceeds to step S9. Although not shown, the through image is displayed even during the focusing operation (step S8).

  When the shutter key 8 is fully pressed, the control unit 22 immediately follows the path from the CCD 13 to the DRAM 21 after the DMA transfer of the image data for one screen captured from the CCD 13 to the DRAM 21 is completed. After stopping and switching to the CCD drive system at the time of actual photographing, which is different from the through image acquisition, the image compression processing is performed on the captured image data, and then the JPEG circuit 27 compresses the image data. Then, the image file (compressed image data) and the value of the camera shake component immediately before the shutter key is fully pressed are associated and recorded and stored in the storage memory 28, and the image data for one sheet is finished (step S9).

  By the operation shown in the flowchart of FIG. 6, the digital camera 100 can detect camera shake and display the camera shake state in time series. Therefore, the photographer can easily grasp the transition of the camera shake, and the shooting instruction (shutter key 8 The digital camera 100 can be consciously stabilized, for example, by firmly holding the camera so that camera shake of the digital camera 100 does not occur until immediately before.

  In the flowchart shown in FIG. 6, steps S2 to S4 are shown as operations subsequent to step S1, but it is actually desirable that the operations are performed in parallel with the through image display.

<Modification>
In the flowchart of FIG. 6, the graph indicating the camera shake state is displayed in chronological order on the through image displayed at the time of shooting. However, if the photographer knows the camera shake state immediately before shooting, the camera will not shake. Since the camera can be stably photographed, the camera shake state from that point to the past may be displayed between the autofocus process and the photographing instruction (shutter key full press).

  FIG. 7 is a flowchart showing another embodiment of the camera shake state notification operation of the digital camera. The processing shown below is basically explained by an example in which the control unit 22 executes in accordance with a program stored in advance in a program memory such as a flash memory, but it is not necessary to store all functions in the program memory. Alternatively, a part or all of them may be received via a network. Hereinafter, an example in which the present invention is applied to the digital camera 1 shown in FIGS. 4 and 5 will be described.

  In the shooting mode, the control unit 22 executes AE processing at a focal length corresponding to the zoom value at that time, obtains image data from the CCD 13, and achieves white balance corresponding to the color of the light source by automatic white balance (AWB) processing. As described above, after adjustment is performed by the color process circuit 18, the VRAM 24 is rewritten with video through image data obtained by thinning out image data from the CCD 13, and a through image is displayed on the display unit 26 (step T1).

  The shake detection unit 31 detects the up / down, left / right, and front / rear shakes (pitch, yaw, roll) of the digital camera 100 and sends detection signals (digital signals) to the control unit 22 at predetermined time intervals. Receives a camera shake detection signal output from the camera shake detection unit 31 at predetermined time intervals (step T2), extracts a camera shake component to be displayed, generates a graph value (step T3), and generates the generated graph value on the DRAM 21. Is stored as the latest value of the time-series graph values stored in the graph value storage area secured in the. At this time, if the graph value storage area is full, the storage area is shifted and the oldest value is erased (step T4).

  The control unit 22 examines the signal from the key input unit 30, and proceeds to step T6 if the shutter key 8 is half-pressed, and returns to step T1 if not pressed (step T5).

  The control unit 22 applies the time series graph values stored in the graph value storage area to the digital video encoder 25 via the VRAM controller 23 to generate a video signal and output the generated video signal to the display unit 26. A time series graph (see FIGS. 1 to 3) is displayed in the graph display field of the screen 5 (step T6), and AF (automatic focusing) processing is performed so that a predetermined focus area is in focus (step T7). If the AF process is finished, the in-focus position is locked and the process proceeds to step T10. If not, the process proceeds to step T9. Although not shown, the through image is displayed even during the focusing operation (step T8).

  The control unit 22 performs the same processing as the above steps T2 to T4, generates a graph value of the camera shake component, and cyclically stores it in the graph value storage area on the DRAM 21 (step T9).

  Next, the control unit 22 checks whether or not the shutter key 8 has been fully pressed. If the shutter key 8 has been fully pressed, the process proceeds to step T11. If not, the process returns to step T9 (step T10).

  When the shutter key 8 is fully pressed, the control unit 22 immediately follows the path from the CCD 13 to the DRAM 21 after the DMA transfer of the image data for one screen captured from the CCD 13 to the DRAM 21 is completed. After stopping and switching to the CCD drive method during actual shooting, which is different from the through image acquisition, the captured image data is subjected to image compression processing. The component values are associated and recorded in the storage memory 28, and photographing of one image data is finished (step T11).

  By the operation shown in the flowchart of FIG. 7, the camera shake state is displayed in time series only at the time of autofocus, so that the photographer can easily grasp the shift and the current state of the camera shake, and the camera shake of the digital camera 100 until the shooting instruction is given. It is possible to consciously stabilize the digital camera 100 by holding the camera firmly so as not to occur. In addition, since the graph is displayed only during autofocus, the graph does not get in the way, and it is easy to determine the composition before autofocus processing.

  In the flowchart shown in FIG. 6, steps T2 to T5 are shown as operations subsequent to step T1, but in practice, it is desirable to perform the steps in parallel with the through image display. Further, there are various programs for displaying as shown in FIGS. 1 to 3, and the program is not limited to the examples of the flowcharts of FIGS.

  Moreover, although the case where the shake detection unit 31 is a device capable of detecting the shake amount and the direction is taken as an example in the flowcharts of FIGS. 6 and 7, a sensor or the like that can detect only the shake amount is available. In the case of a simple device (or a microcomputer or a program programmed to detect only the amount of camera shake), step S2 (T2) is indicated as “the camera shake detection unit 31 is the camera shake (camera shake amount) of the digital camera 100”. And the detection signal (digital signal) is sent to the control unit 22 at predetermined time intervals, so that the control unit 22 receives the camera shake detection signal output from the shake detection unit 31, and “S3 (T3) Is “takes out the amount of camera shake to be displayed and generates a graph value of the amount of camera shake”.

  FIG. 8 is an explanatory diagram of camera shake components. The horizontal direction of the camera 200 is the X axis, the center of the camera 200 is the origin, the vertical axis perpendicular to the X axis is the Y axis, the origin passes through the X axis, Y If the axis perpendicular to the axis is the Z-axis, the pitch is the horizontal blur around the Z-axis, the yaw is the left-right blur around the Y-axis, and the roll is the vertical blur around the X-axis. Means.

  In the description of the above embodiment, a graph indicating the amount of camera shake is displayed when a through image is displayed. However, the graph is always displayed when the power is turned on, when the shutter is half-pressed (half-press of the shutter key), or when in shooting mode. You may make it do.

In the description of the above embodiment, the camera shake amount is displayed and then recorded in association with the captured image. However, based on the camera shake amount immediately after the shutter is fully pressed or when the image is recorded. The image can be corrected and recorded as an image without blurring.

  In the description of the above embodiment, still image shooting is taken as an example, but the present invention can also be applied to moving image shooting. That is, in the moving image shooting mode, an operation program at the time of moving image shooting is configured so as to perform the same processing as steps S2 to S4 in FIG. 6 in parallel with the moving image display, and a part of the screen displaying the moving image is handled. The amount of blur can be displayed in time series.

In addition, the present invention can be applied when shooting with pan and tilt operations. That is, the operation program is configured to perform the same processing as steps S2 to S4 in FIG. 6 between the pan operation or tilt operation and the shooting instruction, that is, camera shake detection, graph value generation, graph display, etc. The amount of camera shake can be displayed in time series on a part of the displayed screen.

(Embodiment 2)
In the first embodiment, the digital camera 100 includes the shake detection unit 31 including a vibration detection device such as an angle sensor / vibration gyro. The camera shake detection unit 31 detects camera shake, graphs the detection results, and displays the time series. Although the camera shake state is notified by displaying it manually, the method for notifying the camera shake state is not limited to this, and the digital camera 100 does not include the shake detection unit 31 device including the vibration detection device. Can also notify the camera shake state. Hereinafter, description will be given based on FIGS. 4 and 9 to 12. The inventor according to the present embodiment is a digital camera 100 in FIG. 4, may be provided with a vibration detection unit 31 as shown in FIG. 5, in the following description, digital camera 100 is 4, in FIG. 5 It is assumed that the shake detection unit 31 is not provided.

9 is a diagram showing an example of a through image displayed on the liquid crystal monitor screen 5 of the digital camera 100, and FIG. 10 is a diagram showing an example in which an enlarged image of a partial image of the through image 90 in FIG. 9 is displayed in a window. is there. 9 and 10, reference numeral 90 indicates a through image, reference numerals 91 and 92 indicate suspension bridge piers, reference numeral 93 indicates a suspension bridge, reference numeral 94 indicates the sea, and reference numeral 95 indicates the sky.
For the sake of explanation, it is assumed that the piers 91 and 92 are painted white, the sky 95 is cloudy and light gray, and the photographer is focusing on the pier 91 and is shooting, the color of the pier 91 is Since it is confused with the background (cloudy weather 95), it may not be clear to the photographer whether or not there is a blur just by looking at the through image 90 as shown in FIG.

Here, when the enlarged image 96 (through image) of the through image 90 (in this example, the tip of the pier 91) is displayed in the window 99 as shown in FIG. 10, the enlarged image 96 and other parts of the through image are displayed. Therefore, the photographer can easily visually recognize the presence or absence of camera shake. In particular, it is easy to determine the presence or absence of blurring by enlarging the front end or the end where blurring is easy to identify and displaying a window near the center of a subject with little blurring. Further, when the color or the like of the enlarged image 96 is highlighted, it becomes easy to compare with other parts of the through image.
In this example, it has been described that the color of the subject is confusing with the background, but even if this is not the case, by enlarging the partial image on the through image and displaying the window, It goes without saying that the comparison can be made and the presence or absence of blurring can be determined.

  FIG. 11 is a flowchart illustrating an example of a shake state notification operation in the digital camera 100. The processing shown below is basically explained by an example in which the control unit 22 executes in accordance with a program stored in advance in a program memory such as a flash memory, but it is not necessary to store all functions in the program memory. Alternatively, a part or all of them may be received via a network. Hereinafter, an example in which the present invention is applied to the digital camera 1 shown in FIGS. 4 and 5 (however, it does not include the shake detection unit 31) will be described.

  In the shooting mode, the control unit 22 executes AE processing at a focal length corresponding to the zoom value at that time, obtains image data from the CCD 13, and achieves white balance corresponding to the color of the light source by automatic white balance (AWB) processing. In this way, after adjusting the color process circuit 18, the VRAM 24 is rewritten with video through image data obtained by thinning out image data from the CCD 13 to display a through image on the display unit 26, and the cursor is moved to a predetermined position on the screen. Display (step U1).

  When the photographer wants to enlarge and display a part of the through-displayed image and display the window, the cursor is moved to the portion of the displayed through-image to be displayed by operating the cursor key 3 and then set. Since the key 4 is pressed, the control unit 22 checks the signal from the key input unit 30, and if the set key 4 is pressed, the process proceeds to step U3, and if not, the process proceeds to step U10 (step U2).

  When the image portion to be enlarged is designated, the control unit 22 examines the position of the cursor (coordinates on the screen 5) at the time when the set key 4 is pressed in step U2, and centered on the position designated by the cursor. The frame of the predetermined size is superimposed and displayed on the screen 5 on which the through image is displayed (step U3).

  Next, partial image data corresponding to a portion surrounded by a frame is cut out from the DRAM 21 (step U4), and the cut-out image data is subjected to enlargement processing at a predetermined magnification (twice in the vertical and horizontal directions in the embodiment) (step U5). The enlarged image data is adjusted by the color process circuit 18 so as to enhance the color and the like, and then superimposed on the video through image data of the VRAM 24 so as to be superimposed on the through image displayed on the screen of the display unit 26. Then, a window is displayed at a predetermined portion on the screen (in the center of the screen in the embodiment) (the enlarged image in the window is also displayed through) (step U6).

  The photographer operates the cursor key 3 to move the frame displayed in the above step U3 when the portion designated for enlargement display is different from the desired portion or when it is desired to enlarge another portion. 22 checks the signal from the key input unit 22 and returns to step U4 if it is determined that the frame moving operation has been performed, and if not, deletes the frame and proceeds to step U8 (step U7).

  When the photographer wants to display the display position of the window at a desired position instead of the center of the screen, the photographer moves the window in which the enlarged partial image is displayed by operating the cursor key 3. The signal from the input unit 30 is examined, and if it is determined that the window moving operation has been performed, the process proceeds to Step U9, and if not, the process proceeds to Step U10 (Step U8).

  When the window moving operation is performed, the control unit 22 adjusts the image data enlarged in step U5 in the color process circuit 18 so as to emphasize the color and the like, and then converts the image data into the video-through image data in the VRAM 24. It superimposes on the through image displayed on the screen of the display unit 26 so as to be superimposed, and displays it in the moved window (step U9).

  The control unit 22 checks the signal from the key input unit 30, and proceeds to step U11 if the shutter key 8 is half-pressed, and returns to step U1 if not pressed (step U10).

  Next, the control unit 22 performs AF (automatic focusing) processing so as to focus on a predetermined focus area, and locks the focusing position when focusing is completed. Although not shown in the drawing, a through image (or a window when an enlarged partial image is displayed in a window) is also displayed during the focusing operation (step U11), and whether or not the shutter key 8 has been fully pressed is determined. If the shutter key 8 is fully pressed, the process proceeds to step U13 (step U12).

  When the shutter key 8 is fully pressed, the control unit 22 immediately follows the path from the CCD 13 to the DRAM 21 after the DMA transfer of the image data for one screen captured from the CCD 13 to the DRAM 21 is completed. After stopping and switching to the CCD drive system at the time of actual photographing, which is different from the through image acquisition, the image compression processing is performed on the captured image data, and then the JPEG circuit 27 compresses the image data. Then, the image file (compressed image data) and the value of the camera shake component immediately before the shutter key is fully pressed are recorded and stored in the storage memory 28, and the photographing of one image data is finished (step U13).

  With the operation shown in the flowchart of FIG. 11, a part of the subject is enlarged and displayed on the screen on which the through image captured when the subject is photographed is displayed, so that the camera shake state is amplified. When the digital camera 100 is shaken, the image displayed in the window appears to be swayed up and down or left and right. Therefore, the photographer can recognize that the camera shake has occurred, and reset the camera. It is possible to suppress blurring. Therefore, even if the digital camera 100 is not particularly equipped with a device for detecting blur, it is possible to obtain an image without camera shake.

  In addition, since an enlarged display portion of the through image can be designated, a front end and an end portion that can easily detect blurring can be enlarged and displayed in a window. In addition, since the window can be displayed at the center of the screen, it is possible to easily compare the enlarged portion with the center portion where there is little blur among the through images, and it is easy to determine the presence or absence of blur.

  In addition, since the display position of the window can be specified, if the window is displayed in a portion where the enlarged portion and the center portion of the through image that is less likely to be compared are easily compared, the enlargement image and the through image in the window Comparison with the part etc. which became becomes easy.

As shown in FIG. 12, when the enlarged image 97 (through image) of the outline of the partial image of the through image 90 (in this example, the tip of the pier 91) is displayed in the window 99, the entire image is complicated or similar. Since the comparison between the contour 97 and the other parts of the through image can be easily performed, the photographer can easily visually recognize the presence or absence of blur such as camera shake. Furthermore, if the outline is thickened or displayed in black and highlighted, it is easy to compare with other parts of the through image.

After performing thickening processing so as to be emphasized (step U6-2), the color process circuit 18 adjusts the color of the partially enlarged image data extracted from the contour to black, and then the video through image data of the VRAM 24 Is superimposed on the through image displayed on the screen of the display unit 26 so as to be superimposed on the window and displayed in a window on a predetermined portion on the screen (in the center of the screen in the embodiment), and the process proceeds to Step U7 (Step U6-3). .

  In the example of FIG. 14, the contour of the partial image enlarged in step U6-1 is extracted, but after extracting the contour of the partial image cut out in step U4 in the previous stage of step U5, In step U5, the contour enlargement process may be performed, and the processes after step U6-2 in FIG. 14 may be performed. In addition, after extracting the outline of the entire image in the previous stage of step U4, the portion specified in step U4 is cut out, and after the enlargement process is performed in step U5, the processes after step U6-1 are performed. May be.
