  The aperture 50 is driven by an iris motor (not shown) to change the opening amount (aperture value). The CPU 110 controls the iris value of the iris 50 by controlling the driving of the iris motor via the iris motor driver 132.

  The image sensor 134 is composed of a color CCD having a predetermined color filter array (for example, a Bayer array). Light incident on the light receiving surface of the image sensor 134 via the photographing optical system 126 is converted into signal charges in an amount corresponding to the amount of incident light by the photodiodes arranged on the light receiving surface.

  A timing generator (TG) 136 mainly generates a timing signal for driving the image sensor 134 in accordance with a command from the CPU 110.

  The AE / AWB detection circuit 154 calculates a physical quantity necessary for AE control and AWB control from the input image signal in accordance with a command from the CPU 110. For example, as a physical quantity necessary for AE control, one screen is divided into a plurality of areas (for example, 16 × 16), and an integrated value of R, G, and B image signals is calculated for each divided area. The CPU 110 detects the brightness of the subject (subject brightness) based on the integrated value obtained from the AE / AWB detection circuit 154, and determines the aperture value and the shutter speed from a predetermined program diagram.

  Further, as a physical quantity necessary for AWB control, one screen is divided into a plurality of areas (for example, 16 × 16), and an average integrated value for each color of R, G, and B image signals is calculated for each divided area. . The CPU 110 obtains the ratio of R / G and B / G for each divided area from the obtained R accumulated value, B accumulated value, and G accumulated value, and R of the obtained R / G and B / G values. The light source type is discriminated based on the distribution in the color space of / G and B / G. Then, according to the white balance adjustment value suitable for the determined light source type, for example, the value of each ratio is approximately 1 (that is, the RGB integration ratio is R: G: B≈1: 1: 1 in one screen). Then, a gain value (white balance correction value) for the R, G, and B signals of the white balance adjustment circuit is determined.

  The AF detection circuit 156 calculates a physical quantity necessary for AF control from the input image signal in accordance with a command from the CPU 110. In the digital camera 10 of the present embodiment, AF control is performed based on the contrast of the image, and the AF detection circuit 156 calculates a focus evaluation value indicating the sharpness of the image from the input image signal.

  The voice input processing circuit 160 processes a voice signal input via the microphone 20 in accordance with a command from the CPU 110, and the voice output processing circuit 162 processes a voice signal to be output from the speaker 42 in accordance with a command from the CPU 110. .

  The operation of the digital camera 10 of the present embodiment configured as described above is as follows.

  As described above, in the digital camera 10 according to the present embodiment, shooting preparation is performed by pressing the release button 22, that is, AE, AF, and AWB are performed, and shooting is performed by pressing the release button.

  FIG. 4 is a flowchart showing a processing procedure at the time of photographing by the digital camera 10 of the present embodiment.

  CPU 110 determines whether the camera mode is set to the shooting mode based on the input from operation unit 112 (step S10).

If it is determined that the shooting mode is set, the CPU 110 determines whether or not the release button 22 is pressed based on an input from the operation unit 112 (step S11). Incidentally, when the release button 22 is depressed, since the output _{S ON} signal to the CPU 110, CPU 110 detects that the release button 22 is pressed with the input of the _{S ON} signal.

  When it is determined that the release button 22 has been pressed, the CPU 110 performs shooting preparation control (step S12). That is, AE, AF, AWB control is executed.

  First, an image for preparation for shooting is picked up by the image pickup device 134 in accordance with the input of the release signal. The image signal output from the image sensor 134 is taken into the memory 120 via the analog signal processing circuit 138, the A / D converter 140, and the image input controller 142, and the AE / AWB detection circuit 154 and the AF detection circuit from the memory 120. Added to 156.

  The AE / AWB detection circuit 154 calculates a physical quantity necessary for AE control and AWB control from the input image signal, and outputs it to the CPU 110. The CPU 110 determines an exposure value (aperture value and shutter speed) and a white balance correction value based on the output from the AE / AWB detection circuit 154.

  The AF detection circuit 156 calculates a physical quantity necessary for AF control from the input image signal, and outputs the calculated physical quantity to the CPU 110. The CPU 110 controls the driving of the focus motor based on the output from the AF detection circuit 156, and focuses the photographing lens 14 on the main subject.

As described above, the CPU 110 prepares for shooting in response to pressing of the release button 22 (step S12). Thereafter, the CPU 110 determines whether or not the release button 22 has been pressed based on an input from the operation unit 112 (step S13). That is, the input of the _{S ON} signal from the release button 22 is detected whether that is OFF.

  When it is determined that the release button 22 is released, that is, it is determined that the finger is released from the release button 22, the CPU 110 determines whether or not the preparation for shooting is completed (step S14). A recording process is executed (step S15).

  First, the image sensor 134 is exposed with the exposure value obtained in the above-described shooting preparation. The image signal output from the image sensor 134 is taken into the memory 120 via the analog signal processing circuit 138, the A / D converter 140, and the image input controller 142, and is added from the memory 120 to the image signal processing circuit 144. The image signal processing circuit 144 performs necessary signal processing on the input image signal to generate image data (YUV data). The generated image data is temporarily stored in the memory 120, then added to the compression / decompression processing circuit 146, compressed in a predetermined compression format, and stored again in the memory 120. The CPU 110 generates an image file of a predetermined format (for example, Exif) in which attached information such as a shooting date / time, an aperture value, and a shutter speed is added to the compressed image data stored in the memory 120, and the media file is transmitted via the media controller 148. Record on storage media.

  As described above, according to the digital camera 10 of the present embodiment, since shooting is performed by releasing the release button 22, even a person unfamiliar with shooting can shoot without causing camera shake. That is, in general, camera shake is caused by an operation of pushing the release button 22 with a finger. Therefore, as in the digital camera 10 of the present embodiment, the camera shake is performed when the finger is released from the release button 22. Generation of camera shake can be effectively prevented.

  In this embodiment, shooting is performed by pressing the release button 22 and shooting is performed by releasing the pressing. However, in the case of a camera without a so-called AE / AF function, nothing is performed by pressing. Then, shooting is performed by releasing the press.

  Further, in the present embodiment, when the release button 22 is a two-stage release button consisting of half-press and full-press, the preparation for shooting is performed by half-pressing, and shooting is performed by releasing the full-press. To do.

  FIG. 5 is a flowchart showing a procedure of photographing processing when a two-stage release button is used.

In the case of the release button of two-stage, and outputs the S1 _ON signal at half-pressed, and outputs an S2 _ON at full press.

  The CPU 110 determines whether or not the camera mode is set to the shooting mode based on the input from the operation unit 112 (step S20).

If it is determined that the shooting mode is set, the CPU 110 determines whether or not the release button 22 is half-pressed based on an input from the operation unit 112 (step S21). As described above, when the release button 22 is half-pressed, an S1 _ON signal is output to the CPU 110. Therefore, the CPU 110 detects that the release button 22 is half-pressed by the input of this S1 _ON signal. If it is determined that the release button 22 is half-pressed, the CPU 110 performs shooting preparation control (step S12).

Thereafter, the CPU 110 determines whether the half-press of the release button 22 is released based on the input from the operation unit 112 (step S14). That is, it is detected whether or not the input of the S1 _ON signal from the release button 22 is turned off.

  If it is determined that the half-press of the release button 22 has been released, the process returns to step S21 to determine again whether or not the release button 22 has been half-pressed.

On the other hand, when determining that the half-press of the release button 22 has not been released, the CPU 110 next determines whether or not the release button 22 has been fully pressed (step S24). As described above, when the release button 22 is fully pressed, an S2 _ON signal is output to the CPU 110. Therefore, the CPU 110 detects that the release button 22 is half-pressed by the input of the S2 _ON signal.

Even when the release button 22 is fully pressed, the S1 _ON signal is continuously output, and both S1 _ON and S2 _ON are input to the CPU 110.

When CPU 110 determines that release button 22 has been fully pressed, CPU 110 determines whether or not full release has been released (step S25). That is, it is detected whether or not the input of the S2 _ON signal from the release button 22 is turned off.

  If it is determined that the release button 22 has not been fully pressed, the process returns to step S23, and the CPU 110 determines again whether or not the half-press of the release button 22 has been released.

  If it is determined in step S25 that the release button 22 has been fully pressed, that is, if it is determined that the finger has been released from the release button 22, the CPU 110 determines whether or not preparation for shooting has been completed (step S26). After completion, shooting and recording processing is executed (step S27).

  Thus, in the case of a two-stage release button, shooting preparation is performed by half-pressing the release button 22, and shooting is performed by releasing the full-press after the full-press. As a result, even a person unfamiliar with shooting can shoot without causing camera shake.

  In the case of the two-stage release button as described above, it is possible to select a normal shooting process and a camera shake correction shooting process. That is, a means for switching ON / OFF of the camera shake prevention mode is prepared, and when the camera shake prevention mode is set to ON by this switching means, control is performed so that shooting is prepared by half-pressing the release button 22 and shooting is performed by releasing the full press. To do. On the other hand, when the camera shake prevention mode is set to OFF, control is performed so that shooting is prepared by half-pressing the release button 22 and shooting is performed by fully pressing the release button 22.

  As a result, the shooting method can be selected according to the user's shooting style, shooting conditions, etc., and the usability is improved.

  Note that switching of the camera shake prevention mode ON / OFF may be, for example, provided with a dedicated switching button, or may be switched on a menu screen or the like.

  Further, when the shutter speed at the time of photographing obtained as a result of the AE process becomes slower than a prescribed shutter speed (for example, 1/60 s or 1 / focal length (35 mm equivalent)), camera shake is automatically prevented. You may comprise so that a mode may be set to ON. In this case, it is preferable that the user can arbitrarily turn on / off the automatic switching function.

  In this embodiment, a push release button is used, but a contact release button (so-called touch sensor type release button) may be used. In this case, it is configured such that shooting is prepared by touching the release button with a finger (implemented only when the AE / AF function is provided) and shooting is performed by releasing the contact.

  In this embodiment, the release button is pressed (half-pressed) to prepare for shooting, and the release is released (full-press released). However, the shooting is performed by pressing (half-pressed). You may make it image | photograph also by press release (full press release). In this case, the image may be previewed on the liquid crystal monitor 30 after shooting, and the image may be recorded on the memory card 150 after inquiring about the presence or absence of recording.
