Description

  The present invention relates to a still image capturing apparatus and a still image capturing method, and more particularly to a still image capturing apparatus and a still image capturing method having various camera control functions such as an autofocus function and a brightness adjustment mechanism.

  Conventionally, there are digital cameras provided with an autofocus function, a brightness adjustment function, and the like. This digital camera includes an imaging unit such as a CCD element, a signal processing unit that performs white balance correction, γ correction, etc. on a video signal generated by the imaging unit, and an image subjected to predetermined signal processing such as JPEG. An image processing unit for compressing the image file, a memory for recording the image-processed video signal, an IC card slot into which an IC card is inserted, an electronic viewfinder such as an LCD (Liquid crystal display), and the operation of the entire camera A control unit for controlling the control.

  Some digital cameras include a shutter button that is pressed in two stages of shallow pressing and deep pressing. In this type of digital camera, when a subject is photographed, when the shutter button is pressed lightly, the signal processing unit performs camera control such as focusing, aperture, and shutter speed on an image drawn in advance from the imaging unit. . Thereafter, the digital camera captures a camera-controlled image by further pressing the shutter button. The captured image data is compressed by the image processing unit and then recorded on the IC card by the control unit.

  However, in a conventional digital camera, after pressing the shutter button, camera control such as focusing and brightness adjustment is performed, and after an optimal image corresponding to the shooting environment is drawn, the process proceeds to image capture. Therefore, it takes a considerable time from pressing the shutter button to capturing an image, and there are cases where the user misses a photo opportunity even in a scene where the user wants to shoot quickly.

  That is, the conventional digital camera detects the focus, brightness, etc. of the image drawn from the imaging unit when the user presses the shutter button deeply at a stroke in an attempt to shoot the subject in a hurry, and the signal processing unit After the camera is controlled such as focusing, adjusting the shutter speed and proper exposure by the aperture, the captured image is captured. Therefore, this digital camera requires a considerable amount of time to control the camera from when the user presses the shutter button to capture the actually drawn image to capture the subject. For this reason, the user may not be able to capture the desired image even when the user presses the shutter button with a photo opportunity. In addition, there is a certain limit in reducing the time required for the camera control itself.

  SUMMARY An advantage of some aspects of the invention is that it provides a still image capturing apparatus and a still image capturing method capable of capturing an image without missing a photo opportunity.

  In order to solve the above-described problem, a still image imaging apparatus according to the present invention is processed by an imaging unit that images a subject, an image processing unit that processes an image signal generated by the imaging unit, and the image processing unit. Image output means for outputting the image, a shutter button serving as a trigger for imaging the subject, and a focus control and exposure correction by controlling the imaging means. A coarse adjustment is performed to generate a first image signal, and the image signal generated by the image pickup means is detected when the shutter button is pressed lightly, and the image pickup means is controlled to respond to the shooting environment. Control means for adjusting the focus control and adjusting the exposure to generate a second image signal, and further recording the second image signal by pressing the shutter button deeply. The control means records the first image signal when it is detected that the shutter button is operated to be lightly pressed and deeply pressed within a predetermined time. is there.

  The present invention also provides an image pickup means for picking up a subject, an image processing means for processing an image signal generated by the image pickup means, an image output means for outputting an image processed by the image processing means, and a shallow press. Alternatively, in a still image capturing method in a still image capturing apparatus configured to be capable of being pressed in two steps of deep pressing and having a shutter button serving as a trigger for capturing an image of a subject, and a control unit that controls the image capturing unit, the image capturing unit includes: By performing control, coarse adjustment of focus control and exposure correction is performed to generate a first image signal, and when the shutter button is pressed lightly, the image signal generated by the imaging unit is detected, and the imaging unit To adjust the focus control and exposure correction according to the shooting environment to generate a second image signal, and then the shutter button is pressed down to make the second image No. is recorded, is obtained so as to record the first image signal by operation of the pressing operation and the depth of the shutter button is pressed shallow within a predetermined time is performed.

  According to the present invention, the urgent level of image capture by the user is estimated according to the pressing speed of the shutter button, and an image captured before camera control is captured. Therefore, the time required for normal camera control is reduced. Since the image is captured with the omission, an image closer to a photo opportunity can be taken, and the photo opportunity can be prevented from being missed.

  Hereinafter, a digital camera which is a still image capturing apparatus to which the present invention is applied will be described in detail with reference to the drawings.

  As shown in FIG. 1, the digital camera 1 includes an imaging unit 4 that generates an image signal of a subject, a signal processing unit 5 that performs A / D conversion on the image signal, and performs white balance correction and γ correction, and signal processing. A memory 6 for storing the image signal processed by the unit 5; an image processing unit 7 for compressing the image signal recorded in the memory 6; and a control unit 8 for controlling a photographing operation using these mechanisms. .

  The digital camera 1 has an LCD panel 9 serving as an electronic viewfinder, and an image captured from the imaging unit 4 is displayed. In addition, the digital camera 1 has a mounting portion on which an IC card for recording a compressed image signal is mounted.

  An imaging unit 4 that captures an image of a subject and generates an image signal is provided on the front surface of the housing of the digital camera 1 and is attached with an imaging element such as an imaging lens 12 and a CCD element 13.

  The imaging lens 12 of the imaging unit 4 is connected to a lens control unit 14 and is subjected to focus control by the lens control unit 14 that receives a control signal from the control unit 8. The CCD element 13 of the imaging unit 4 is connected to the CCD control unit 15 and is controlled by the CCD control unit 15 that receives a control signal from the control unit 8.

  The CCD element 13 generates an image signal from the light taken in from the imaging lens 12. Then, the CCD element 13 outputs the generated image signal to the signal processing unit 5 and the detection unit 17.

  The detection unit 17 detects a high frequency component, a brightness component, and the like of the image signal and outputs detection data to the control unit 8. The control unit 8 extracts information necessary for focusing and brightness adjustment based on the detection data of the received image signal, generates a control signal, and then sends the control signal to the lens control unit 14 or the CCD control unit 15. The image pickup lens 12 and the CCD element 13 are controlled.

  The signal processing unit 5 that performs various signal processing on the image signal output from the CCD element 13 performs A / D conversion on the image signal generated by the CCD element 13 and receives a control signal from the control unit 8 to perform white balance. Make corrections and gamma corrections. The signal processing unit 5 is connected to a memory 6 that stores image signals, and outputs the image signals subjected to signal processing to the memory 6.

  The image processor 7 and the image display circuit 20 are connected to the data bus of the memory 6. The image processing unit 7 compresses the image signal stored in the memory 6 into a predetermined file format such as JPEG. Thereafter, the image processing unit 7 outputs the compressed image signal to the IC card mounted via the card interface.

  The image display circuit 20 converts the image signal stored in the memory 6 and outputs the image to the LCD panel 9 serving as an electronic viewfinder.

  In the digital camera 1, a shutter button 25 serving as a trigger for capturing a subject is formed on the upper surface of the housing. The shutter button 25 is formed so that it can be pressed in two stages of shallow pressing and deep pressing. The shutter button 25 is connected to a detection switch 26 that detects a pressed state. The detection switch 26 is connected to the control unit 8 described later, and thus the shutter button 25 is in a state where it is not pressed at all, a state where it is pressed lightly, or a state where it is pressed deeply. Each pressed state is detected.

  The control unit 8 that controls the photographing operation is composed of an MPU (microprocessing unit) and is mounted via the card interface 21 in addition to the lens control unit 14, the CCD control unit 15, the detection unit 17, the image display circuit 20, and the like described above. Connected to the IC card.

  When photographing the subject, the control unit 8 receives data such as high-frequency components and brightness components of the image signal output from the imaging unit 4 and focus data of the captured image from the detection unit 17, and corrects the white balance. Then, control signals necessary for camera control such as exposure correction by the shutter speed and aperture and focusing are output to the lens control unit 14 and the CCD control unit 15. Then, the control unit 8 outputs the image signal stored in the memory 6 to the image processing unit 7, and outputs the compressed image data to the IC card.

  The control unit 8 is connected to a detection switch 26 that detects a pressed state of the shutter button 25, and detects a pressing transition of the shutter button 25. Then, the control unit 8 captures an image after the camera control or captures a plurality of images before and after the camera control and selects one of the images in accordance with the pressing transition of the shutter button 25.

  The detection switch 26 that is connected to the control unit 8 and detects the pressed state of the shutter button 25 includes a first switch 26 a that detects a state where the shutter button 25 is pressed lightly and not pressed deeply, and the shutter button 25. And a second switch 26b for detecting a state where the button is pressed lightly and deeply. The first and second switches 25a and 25b are input according to the stroke of pressing the shutter button 25. The detection switch 26 receives the first switch 26a when the shutter button 25 is pressed lightly. When the first switch 26a is input, the control unit 8 that detects the first switch 26a controls the imaging unit 4 to perform focusing according to the imaging environment, and to perform exposure correction by the shutter speed and the aperture, thereby generating the second image. Generate a signal.

  The detection switch 26 receives the second switch 26b when the shutter button 25 is pressed deeply. When the second switch 26b is input, the control unit 8 that has detected this captures the second image signal that has been subjected to focusing by the imaging unit 4 and exposure correction by the shutter speed and aperture according to the shooting environment. To do.

  The digital camera 1 configured as described above is used as follows.

  The digital camera 1 captures an image after performing camera control such as exposure correction for adjusting the focus and the aperture and the shutter speed in accordance with the shooting environment in accordance with the pressing transition of the shutter button 25 of the user, Further, after capturing the first image signal generated by coarsely adjusting the image capturing unit 4 in advance, the camera control of the image capturing unit 4 is further performed to generate the second image signal, and then the second image signal is captured. To do.

  Specifically, as shown in FIG. 2, in the digital camera 1, before the shutter button 25 is pressed, the pre-camera control is performed by the control unit 8, and the lens control unit 14 and the CCD control unit 15 are driven to take an image. The first image signal is generated by performing coarse adjustment such as focusing and brightness adjustment by the unit 4. At this time, the control unit 8 detects data necessary for focusing, exposure correction, and the like from the image data generated by the imaging unit 4 and performs a predetermined calculation process, and then the lens control unit 14 and the CCD control unit 15. And a control signal is output to the image display circuit 20 and the like, and the coarsely adjusted image is displayed on the LCD panel 9. Note that the imaging unit 4 performs the above rough adjustment so that the moving image can be immediately responded even when the digital camera 1 captures the moving image.

  When the shutter button 25 is pressed in two steps from a shallow press to a deep press at a certain time interval, the control unit 8 causes the first switch 26a to be pressed when the shutter button 25 is pressed lightly. Is input as a trigger to drive the lens control unit 14 and the CCD control unit 15, thereby performing camera control such as exposure correction for adjusting the focusing, aperture, shutter speed, and the like for the imaging unit 4. A second image signal is generated. Thereafter, the control unit 8 captures an image generated by the camera control triggered by the input of the second switch 26b when the shutter button 25 is pressed deeply, and stores the image data in the memory 6. Output. Next, the control unit 8 outputs the image data in the memory 6 to the image processing unit 7, compresses the image data into a predetermined file format such as JPEG, and the compressed image data is connected to the IC connected via the card interface 21. Output to card.

  As shown in FIG. 3, the control unit 8 inputs the first and second switches 26a and 26b within a certain period of time when the shutter button 25 is pressed all at once from a shallow press to a deep press. With this as a trigger, an image signal generated by coarsely adjusting the imaging unit 4 in advance by pre-camera control before the shutter button 25 is pressed is captured, and image data is output to the memory 6. Thereafter, the control unit 8 outputs a control signal to the imaging unit 4 to perform camera control such as focus correction and exposure correction by adjusting the aperture and shutter speed according to the shooting environment. Thereafter, the control unit 8 captures an image signal generated by camera control and outputs the image data to the memory 6. Thereafter, the control unit 8 compares the captured images before and after the camera control, and the evaluation value of the captured image before the camera control is less than or equal to a predetermined threshold based on predetermined parameters such as focus accuracy and exposure amount. If there is, this is output to the image processing unit 7, and after compression processing, an image signal is output to the IC card.

  In this way, the control unit 8 is connected to the detection switch 26 that detects the pressed state of the shutter button 25, and whether the shutter button 25 is pressed deeply within a certain time or until it is pressed deeply within a certain time. First, it is detected whether it was pressed in two stages. When the shutter button 25 is pressed all at once, it is determined that the urgency of the user's image capture is high. Therefore, the control unit 8 performs pre-camera control before performing camera control such as focusing and exposure correction. The image signal generated by is captured. And the control part 8 performs contrast evaluation with the image captured after camera control based on the predetermined parameter for the image generated by this pre-camera control. As a result, when the evaluation value of the image generated by the pre-camera control is equal to or less than a predetermined threshold, the control unit 8 selects the image generated by the pre-camera control, compresses it, and records it on the IC card. .

  Therefore, according to the digital camera 1 to which the present invention is applied, it is possible to take an image of a subject while saving the time required for camera control, and it is possible to record an image closer to a photo opportunity. Even in this case, the image generated by the pre-camera control recorded on the IC card is comparable to the image captured after the camera control in various parameters (focal accuracy, exposure amount, etc.), and after the camera control. It is an image in which the state closer to the photo opportunity is recorded for the time required for camera control than the captured image.

  The control unit 8 may capture the image before and after the camera control and display the image output to the memory 6 on the LCD panel 9 so that the user can select the image. That is, the control unit 8 stores the image captured before the camera control in the memory 6 and displays it on the LCD panel 9 together with the image captured after the camera control for selection by the user. Then, the control unit 8 outputs to the image processing unit 7 either or both of the image selected by the user, the image captured at a time close to the shutter chance without the camera control, and the image captured after the camera control. And record it on the IC card. Thus, the user can select an image captured after camera control corresponding to the shooting environment is compared with an image captured with pre-camera control and in a state closer to a photo opportunity. it can.

  Next, the operation of the digital camera 1 to which the present invention is applied will be described.

  As shown in FIG. 4, the digital camera 1 to which the present invention is applied is in a state where the system such as the control unit 8 is activated when the apparatus is turned on in step S1. In step S2, the control unit 8 performs, as preprocessing, an image signal generated by pre-camera control, which is given when capturing an image captured by roughly adjusting the imaging unit 4 before camera control. The flag for determining whether or not the capture has been performed is cleared. Next, in step S3, the control unit 8 sets the camera control mode to the “pre-camera control” mode, and performs pre-camera control such as focus and brightness on the imaging unit 4 before the shutter button 25 is pressed. And capture the image. That is, the control unit 8 performs a predetermined calculation on the image signal previously captured by the imaging unit 4 based on the image information transmitted by the detection unit 17 and transmits the control signal to the imaging unit 4. Perform focus adjustment and exposure compensation. The image signal generated by the pre-camera control is displayed on the LCD panel 9 serving as an electronic viewfinder via the image display circuit 20.

  In step S <b> 4, the control unit 8 detects whether the shutter button 25 is pressed deeply within a predetermined time by detecting an operation transition of the detection switch 26. When the shutter button 25 is not pressed down at a stroke within a predetermined time, the control unit 8 detects whether or not the shutter button 25 is pressed lightly in step S5. Then, the control unit 8 repeatedly detects an operation transition of the shutter button 25 when the shutter button 25 is not pressed down at a stroke and is not pressed down within a certain time.

  Such a loop for monitoring the operation transition of the shutter button 25 is formed by counting a certain time during which the degree of urgency for capturing an image is estimated. The shutter button 25 is pressed deeply in one loop, When the first and second switches 25a and 25b are input, it is determined that the urgency of the user's image capture is high, and the imaging unit 4 is coarsely adjusted in advance by pre-camera control by the control unit 8 first. The captured image is captured. Specifically, when the shutter button 25 is deeply pressed in one loop and the first and second switches 25a and 25b are input, the control unit 8 is captured before camera control in step S6. It is determined whether or not the captured image can be captured. Next, the control unit 8 captures the image captured by the imaging unit 4 in step S7, and sets a flag for determining that the image has been captured before camera control in step S8. Thereafter, in step S9, the control unit 8 shifts to camera control corresponding to the shooting environment in the same manner as in normal shooting, and captures an image captured from the image pickup unit 4 on which the camera control is performed. Therefore, since the control unit 8 captures an image while omitting the time required for normal camera control, it can also capture an image closer to a photo opportunity.

  On the other hand, if the shutter button 25 is not pressed deeply in the one loop, but only lightly pressed and only the first switch 26a is input, the user's urgent image capture is not high in step S10. Thus, the control unit 8 performs camera control such as exposure correction by controlling the focusing and the aperture and shutter speed according to the shooting environment. Specifically, when the shutter button 25 is lightly pressed in one loop and only the first switch 26a is input, the control unit 8 performs focusing and exposure based on the image data captured from the imaging unit 4. A calculation process necessary for correction is performed, a control signal is transmitted to the imaging unit 4 to perform camera control, and a normal shooting mode is set to capture an image captured by the imaging unit 4 that has undergone camera control. At this time, when the shallow release of the shutter button 25 is released in step S11, the control unit 8 performs coarse adjustment of the image captured in the imaging unit 4 again by the pre-camera control and displays it on the LCD panel 9. "Camera control" mode.

  Next, in step S12, the control unit 8 forms a loop for detecting whether or not the shutter button 25 is further pressed from the lightly pressed state. Then, when the shutter button 25 is pressed down deeply, the control unit 8 waits for the above-described camera control to end in step S13, and captures the camera-controlled image in step S14. Therefore, the user can take an image in which the focus, the exposure amount, and the like are adjusted with higher accuracy.

  Next, in step S15, the control unit 8 determines the presence / absence of a flag for determining whether an image generated by the imaging unit 4 coarsely adjusted by the pre-camera control is captured. If there is a flag, the control unit 8 evaluates the image generated by the imaging unit 4 coarsely adjusted by the pre-camera control in step S16 based on various parameters, and the evaluation value is equal to or less than a predetermined threshold value. It is determined whether or not. This parameter is, for example, focus accuracy or exposure amount. In step S <b> 17, when the evaluation value of the image generated and captured by the pre-camera control is equal to or less than a predetermined threshold value, the control unit 8 selects this image.

  On the other hand, when the image generated by the imaging unit 4 coarsely adjusted by pre-camera control is not captured and the above-described determination flag is cleared, or generated by the imaging unit 4 coarsely adjusted by pre-camera control When the evaluation value of the captured image is higher than the predetermined threshold value, in step S18, the control unit 8 selects an image generated and captured by the camera-controlled imaging unit 4.

  Next, the control unit 8 outputs the image selected in step S17 or step S18 to the memory 6, and in step S19, outputs it to the image processing unit 7, compresses it into a predetermined file format such as JPEG, and in step S20. Then, the compressed image data is written to the IC card mounted via the card interface 21.

  As described above, according to the digital camera 1 to which the present invention is applied, the urgency of the image capture of the user is estimated according to the pressing transition of the shutter button 25, and rough adjustments such as focus accuracy and brightness are performed. The image captured in the image capturing unit 4 is based on an image captured from the image capturing unit 4 that has been subjected to camera control such as focus control and exposure correction according to the shooting environment, and predetermined parameters such as focus accuracy and exposure amount. To evaluate. Then, the control unit 8 of the digital camera 1 selects the image when the evaluation value of the image generated and captured by the pre-camera control is equal to or less than a predetermined threshold, outputs the image to the image processing unit 7, and outputs it to the IC card. Record.

  Therefore, according to the digital camera 1 to which the present invention is applied, it is possible to record a captured image while omitting the time required for normal camera control. A close image can be taken.

  Note that the digital camera 1 can be switched so as to capture only the image captured by the imaging unit 4 that has performed the camera control, regardless of the depression of the shutter button 25.

In other words, when the subject is dark and it is necessary to emit a flash, if the flash is emitted when capturing an image generated by pre-camera control, the flash is emitted when capturing an image of the camera-controlled imaging unit 4 May not be in time. Then, waiting for the strobe light emission may increase the delay from the photo opportunity. Also, if the subject is dark and it is necessary to slow down the shutter speed, it takes more time to capture the image. Therefore, if the image generated by the pre-camera control is captured, it is captured after the camera control. When capturing an image, the delay from the photo opportunity may increase. Furthermore, even if the image is captured after the focus, brightness, etc. are sufficiently adjusted by camera control, there may be a case where the photo opportunity is in time.

  Therefore, when the control unit 8 detects that it is necessary to slow down the flash emission or the shutter speed based on the image signal generated by the pre-camera control, the control unit 8 automatically prohibits the capture of the image generated by the pre-camera control. . Specifically, as shown in FIG. 5, the control unit 8 presses the shutter button 25 from a shallow press to a deep press at a stroke, and the first and second switches 26a and 26b are input within a certain time. Even if the image data is detected from the image captured from the image pickup unit 4 that has been subjected to rough adjustment such as focusing and brightness adjustment before the shutter button 25 is pressed, the flash emission is performed. If it is determined that the shutter speed needs to be reduced, the normal shooting mode is set. Then, the control unit 8 performs camera control such as focus control and exposure correction by adjusting the aperture and shutter speed. After that, the control unit 8 captures the camera-controlled image immediately after the camera control is finished, outputs the data to the memory 6 and the image processing unit 7, compresses the image data, and writes it to the IC card.

  In this case, the control unit 8 prohibits capturing of an image captured before the camera control. Therefore, in step S4 shown in FIG. 4, the control unit 8 presses the shutter button 25 all at once in one loop for monitoring the operation transition of the shutter button 25, and the first and second detection switches 26a and 26b are input. Even in such a case, in step S6, camera control is performed in the normal shooting mode, and an image is captured after the camera control.

  As a result, the digital camera 1 to which the present invention is applied does not capture an image generated by the pre-camera control and does not capture an image generated when pre-flash shooting or shooting with a slow shutter speed is performed. Therefore, it is possible to capture an image on which camera control such as focusing and exposure amount adjustment has been performed without significant delay.
