<Description of image sensor>
FIG. 2 is a diagram showing an outline of the image sensor 21 according to the present embodiment. 2 shows a state in which the light incident side of the image sensor 21 is the upper side. Therefore, in the following description, the direction on the light incident side of the image sensor 21 is “upper” or “upper”, and the direction opposite to the light incident side is “lower” or “lower”. The image sensor 21 includes an upper photoelectric conversion layer 31 and a lower photoelectric conversion layer 32. The upper photoelectric conversion layer 31 and the lower photoelectric conversion layer 32 are stacked on the same optical path. The upper photoelectric conversion layer 31 is composed of an organic photoelectric film that absorbs (photoelectric converts) light of a predetermined color component (details will be described later). The light of the color component that has not been absorbed (photoelectric conversion) by the upper photoelectric conversion layer 31 passes through the upper photoelectric conversion layer 31 and enters the lower photoelectric conversion layer 32, and is photoelectrically converted by the lower photoelectric conversion layer 32. The lower photoelectric conversion layer 32 performs photoelectric conversion using a photodiode. The color component photoelectrically converted by the upper photoelectric conversion layer 31 and the color component photoelectrically converted by the lower photoelectric conversion layer 32 have a complementary color relationship. The upper photoelectric conversion layer 31 and the lower photoelectric conversion layer 32 are formed on the same semiconductor substrate, and each pixel position corresponds to one to one. For example, the pixel in the first row and the first column of the upper photoelectric conversion layer 31 corresponds to the pixel in the first row and the first column of the lower photoelectric conversion layer 32.

  FIG. 3A is a diagram illustrating a pixel arrangement of the upper photoelectric conversion layer 31. In FIG. 3A, the horizontal direction is the x-axis, the vertical direction is the y-axis, and the coordinates of the pixel P are expressed as P (x, y). In the example of the upper photoelectric conversion layer 31 shown in FIG. 3A, organic photoelectric films that photoelectrically convert Mg (magenta) and Ye (yellow) light are alternately arranged in each pixel in an odd row, and each pixel in an even row. Organic photoelectric films that photoelectrically convert Cy (cyan) and Mg (magenta) light are alternately arranged in the pixel. Light that is not received by each pixel is transmitted. For example, the pixel P (1,1) photoelectrically converts Mg light and transmits G (green) light which is a complementary color of Mg. Similarly, the pixel P (2,1) photoelectrically converts Ye light and transmits B (blue) light, which is a complementary color of Ye, and the pixel P (1,2) photoelectrically converts Cy light. Transmits light of R (red) which is a complementary color of Cy.

  FIG. 3B is a diagram illustrating a pixel arrangement of the lower photoelectric conversion layer 32. Each pixel position shown in FIG. 3B is the same as that in FIG. For example, the pixel (1, 1) of the lower photoelectric conversion layer 32 corresponds to the pixel (1, 1) of the upper photoelectric conversion layer 31. In FIG. 3B, the lower photoelectric conversion layer 32 is not provided with a color filter or the like, and is a color component that passes through the upper photoelectric conversion layer 31 (that is, a color component that is absorbed and photoelectrically converted by the organic photoelectric film). (Complementary color) is photoelectrically converted. Therefore, as shown in FIG. 3C, in the lower photoelectric conversion layer 32, the image signals of the G and B color components are output in the odd-numbered pixels, and the image signals of the R and G color components are output in the even-numbered pixels. can get. For example, in the pixel P (1, 1), an image signal of a G component having a complementary color of Mg is obtained. Similarly, an image signal of a complementary B component of Ye is obtained at the pixel P (2,1), and an image signal of an R component of a complementary color of Cy is obtained at the pixel P (1,2).

  Thus, in the imaging device 21 according to the present embodiment, the upper photoelectric conversion layer 31 formed of an organic photoelectric film plays a role of a color filter with respect to the lower photoelectric conversion layer 32, and the upper photoelectric conversion layer 32 to the upper photoelectric conversion layer 32. A complementary color image (bayer array image in the example of FIG. 3) of the conversion layer 31 is obtained. Therefore, in the image sensor 21 according to the present embodiment, a CMY image composed of three colors of Cy, Mg, and Ye can be acquired from the upper photoelectric conversion layer 31, and R, G, and B can be acquired from the lower photoelectric conversion layer 32. The RGB image which consists of these three colors can be acquired.

  FIG. 4 is a diagram illustrating a part of a cross section of the image sensor 21. As shown in FIG. 4, in the imaging element 21, a lower photoelectric conversion layer 32 formed on a silicon substrate and an upper photoelectric conversion layer 31 using an organic photoelectric film are stacked via a wiring layer 40. Above the upper photoelectric conversion layer 31, one microlens ML is formed for one pixel. For example, in the upper photoelectric conversion layer 31, the light receiving part PC (1,1) by the organic photoelectric film that constitutes the photoelectric conversion part of the pixel P (1,1) is the subject incident from the microlens ML (1,1). The light of Mg in the light is photoelectrically converted to transmit the light of G which is a complementary color. In the lower photoelectric conversion layer 32, the photodiode PD (1, 1) constituting the pixel P (1, 1) receives the G light transmitted through the light receiving portion PC (1, 1) of the upper photoelectric conversion layer 31. To photoelectrically convert.

  FIG. 5 is a diagram illustrating a circuit configuration of one pixel P (x, y) in the image sensor 21. The pixel P (x, y) includes a photodiode PD, a transfer transistor Tx, a reset transistor R2, an output transistor SF2, and a selection transistor SEL2 as a circuit for configuring the lower photoelectric conversion layer 32. The photodiode PD accumulates charges according to the amount of incident light. The transfer transistor Tx transfers the charge accumulated in the photodiode PD to the floating diffusion region (FD portion) on the output transistor SF2 side. The output transistor SF2 constitutes a current source PW2 and a source follower via the selection transistor SEL2, and outputs an electric signal corresponding to the electric charge accumulated in the FD section as an output signal OUT2 to the vertical signal line VLINE2. The reset transistor R2 resets the charge in the FD portion to the power supply voltage Vcc.

  Further, the pixel P (x, y) includes a light receiving unit PC using an organic photoelectric film, a reset transistor R1, an output transistor SF1, and a selection transistor SEL1 as a circuit for configuring the upper photoelectric conversion layer 31. The light receiving unit PC using an organic photoelectric film converts non-transmitted light into an electrical signal corresponding to the amount of light, and outputs a vertical signal line as an output signal OUT1 via a selection transistor SEL1 and an output transistor SF1 constituting a source follower. Output to VLINE1. The reset transistor R1 resets the output signal of the light receiving unit PC to the reference voltage Vref. Further, a high voltage Vpc is applied for the operation of the organic photoelectric film. Each transistor is composed of a MOS_FET.

  Here, the operation of the circuit according to the lower photoelectric conversion layer 32 will be described. First, when the selection signal φSEL2 becomes “High”, the selection transistor SEL2 is turned on. Next, when the reset signal φR2 becomes “High”, the FD portion is reset to the power supply voltage Vcc, and the output signal OUT2 also becomes the reset level. Then, after the reset signal φR2 becomes “Low”, the transfer signal φTx becomes “High”, the charge accumulated in the photodiode PD is transferred to the FD portion, and the output signal OUT2 changes according to the amount of charge. Start and stabilize. Then, the transfer signal φTx becomes “Low”, and the signal level of the output signal OUT2 read from the pixel to the vertical signal line VLINE2 is determined. The output signal OUT2 of each pixel read out to the vertical signal line VLINE2 is temporarily held for each row in a horizontal output circuit (not shown) and then output from the image sensor 21. In this way, a signal is read from each pixel of the lower photoelectric conversion layer 32 of the image sensor 21.

  The operation of the circuit relating to the upper photoelectric conversion layer 31 will be described. First, when the selection signal φSEL1 becomes “High”, the selection transistor SEL1 is turned on. Next, the reset signal φR1 becomes “High”, and the output signal OUT1 also becomes the reset level. Then, immediately after the reset signal φR1 becomes “Low”, the charge accumulation of the light receiving portion PC by the organic photoelectric film is started, and the output signal OUT1 changes according to the amount of charge. The output signal OUT1 is temporarily held for each row in a horizontal output circuit (not shown), and then output from the image sensor 21. In this way, a signal is read from each pixel of the upper photoelectric conversion layer 31 of the image sensor 21.

<Movie mode and still image mode>
In the digital camera 1 of the present embodiment, as a driving mode of the upper photoelectric conversion layer 31 and the lower photoelectric conversion layer 32 of the image sensor 21, a moving image mode for outputting a moving image signal and an image signal for a still image are output. Still image mode is provided. The moving image mode is a mode in which drive conversion is performed so that photoelectric conversion is performed at a set frame rate, pixel addition and thinning are performed so that a predetermined number of pixels is obtained, and image signals are output. On the other hand, the still image mode is a mode in which photoelectric conversion is performed with a set exposure time, and drive control is performed so that, for example, readout is performed from all pixels without pixel addition and thinning and an image signal is output. That is, drive control is performed so that the number of pixels of the still image is larger than that of the moving image. The moving image mode is a mode used both when generating a moving image for recording to be recorded on the memory card 17 and when generating a display image to be displayed on the liquid crystal monitor 15 as a through image.

<Shooting mode for taking still pictures during movie shooting>
The digital camera 1 of the present embodiment is provided with a moving image still image shooting mode capable of performing still image shooting during moving image shooting in addition to a normal still image shooting mode and a normal moving image shooting mode as shooting modes. It has been. In the moving image still image shooting mode, the digital camera 1 starts moving image shooting when the recording button is pressed, and ends moving image shooting when the recording button is pressed again, and records the shot moving image in the memory card 17. To do. When the release button is pressed during moving image shooting, the digital camera 1 performs still image shooting and records the shot still image in the memory card 17.

  Here, for comparison with the present embodiment, an example in which still image shooting is performed during moving image shooting in a conventional digital camera will be described with reference to FIG. As shown in FIG. 6A, in the conventional digital camera, when moving image shooting is instructed by pressing a recording button, the image sensor is driven in the moving image mode to perform moving image shooting.

  When a still image shooting is instructed by pressing the release button, the conventional digital camera changes the drive mode of the image sensor from the moving image mode to the still image mode and performs still image shooting. When the still image shooting is completed, the conventional digital camera changes the drive mode of the image sensor from the still image mode to the moving image mode again, and resumes moving image shooting.

  As described above, in the conventional digital camera, when taking a still image during moving image shooting, the drive mode of the image sensor is changed from the moving image mode to the still image mode, so that time (mode change time) is required. Therefore, there is a time lag between when the still image shooting is instructed and when the still image shooting is performed. In addition, moving image shooting cannot be performed during still image shooting, so that frames of the moving image are dropped.

  Based on the problems of the conventional digital camera as described above, the digital camera 1 according to the present embodiment does not cause a time lag from when a still image shooting is instructed until a still image shooting is actually performed, and a frame drop of a moving image does not occur. The shooting process is performed.

  FIG. 6B is a diagram illustrating a driving mode in the moving image still image shooting mode in the digital camera 1 of the present embodiment. When the moving image shooting is instructed by pressing the recording button, the drive control unit 111 drives the upper photoelectric conversion layer 31 of the image sensor 21 in the moving image mode to perform moving image shooting. The image processing unit 14 generates moving image data based on the image signal output from the upper photoelectric conversion layer 31 and records it in the memory card 17.

  When the release button is pressed to instruct still image shooting, the drive control unit 111 drives the lower photoelectric conversion layer 32 in the still image mode to perform still image shooting. The image processing unit 14 generates still image data based on the image signal output from the lower photoelectric conversion layer 32 and records it in the memory card 17.

  As described above, the digital camera 1 drives the upper photoelectric conversion layer 31 in the moving image mode when the moving image shooting is instructed in the moving image still image shooting mode, and the lower photoelectric conversion layer when the still image shooting is instructed during the moving image shooting. 32 is driven in the still image mode. Therefore, in the digital camera 1 of the present embodiment, the mode change time from the moving image mode to the still image mode is not required unlike the conventional digital camera, and the still image is generated without causing a time lag after the still image shooting is instructed. You can take pictures.

  The drive control unit 111 continues driving the upper photoelectric conversion layer 31 in the moving image mode and continues moving image shooting while the lower photoelectric conversion layer 32 is driven in the still image mode. Therefore, in the digital camera 1 of the present embodiment, it is possible to prevent frames from being dropped during moving image shooting.

<Long exposure shooting mode>
Further, the digital camera 1 of the present embodiment is provided with a long exposure shooting mode for shooting a still image with a long exposure time. When the digital camera 1 is switched to the long exposure shooting mode by the mode switching button, the display of the through image is started. When the release button is pressed, the digital camera 1 performs long exposure shooting and records the shot long exposure image in the memory card 17. Note that the exposure time in long exposure photography is, for example, a long time of several tens of seconds to 1 minute or more.

  Here, for comparison with the present embodiment, an example in which long exposure shooting is performed in a conventional digital camera will be described with reference to FIG. As shown in FIG. 7A, when the conventional digital camera is switched to the long-exposure shooting mode by the mode switching button, the image pickup device is driven in the moving image mode and the through based on the image signal picked up by the image pickup device is used. Display the image.

  When a still image shooting is instructed by pressing the release button, the conventional digital camera performs a predetermined exposure calculation process based on the image imaged by the imaging device immediately before this, and performs long exposure shooting. Determine the exposure time at. Further, the conventional digital camera changes the drive mode of the image sensor from the moving image mode to the still image mode, and performs long exposure shooting with the predetermined exposure time determined above.

  In such a conventional digital camera, a through image cannot be displayed during long exposure shooting, and thus the user cannot check the shooting range (shooting angle of view). In addition, in a conventional digital camera, a predetermined exposure time is determined in advance based on the brightness of the shooting screen before long exposure shooting, so when the brightness of the shooting screen changes during long exposure, There is a possibility that an image with an appropriate exposure amount cannot be obtained. For example, there may be a case where the shooting screen suddenly becomes brighter during long exposure, the image signal reaches a saturation level before the end of exposure, and whiteout occurs in the image signal.

  Based on the problems of the conventional digital camera as described above, the digital camera 1 of the present embodiment can check the shooting range even during long exposure shooting, and the brightness of the shooting screen changes during long exposure. In such a case, photographing processing is performed so that an image with an appropriate exposure amount can be obtained.

  FIG. 7B is a diagram illustrating a drive mode in the long exposure shooting mode in the digital camera 1 of the present embodiment. The drive control unit 111 drives the upper photoelectric conversion layer 31 of the image sensor 21 in the moving image mode when switched to the long exposure shooting mode by the mode switching button. The image processing unit 14 generates a display image based on the image signal output from the upper photoelectric conversion layer 31. The display control unit 113 displays the display image generated by the image processing unit 14 on the liquid crystal monitor 15 as a through image.

  Then, when a still image shooting is instructed by pressing the release button, the drive control unit 111 drives the lower photoelectric conversion layer 32 in the still image mode to start long-time exposure still image shooting. In the lower photoelectric conversion layer 32, charge accumulation is continued until there is a trigger for the end of exposure described later.

  The drive control unit 111 continues driving the upper photoelectric conversion layer 31 in the moving image mode even during long exposure photography. The display control unit 113 continues displaying the through image based on the image signal output from the upper photoelectric conversion layer 31. As a result, the digital camera 1 can allow the user to check the shooting range (shooting angle of view) with a through image even during long exposure shooting.

  Further, the long-time exposure control unit 112 monitors the image signal output from the upper photoelectric conversion layer 31 during the long-time exposure shooting, and determines the timing for ending the exposure of the lower photoelectric conversion layer 32. Specifically, when exposure of the lower photoelectric conversion layer 32 is started, the image processing unit 14 integrates image signals output from the upper photoelectric conversion layer 31 at a predetermined frame rate. When the image signal integrated by the image processing unit 14 reaches a level immediately before saturation, the long-time exposure control unit 112 ends the exposure of the lower photoelectric conversion layer 32 as a trigger for the end of exposure. As a result, the digital camera 1 can obtain a long-time exposure image that prevents saturation of the image signal output from the lower photoelectric conversion layer 32 and suppresses overexposure regardless of a change in brightness of the shooting screen. .

  When the exposure of the lower photoelectric conversion layer 32 is completed in this way, the image processing unit 14 generates still image data based on the image signal output from the lower photoelectric conversion layer 32 and records it in the memory card 17. .

According to the embodiment described above, the following operational effects can be obtained.
(1) In the digital camera 1, the drive control unit 111 drives the upper photoelectric conversion layer 31 in the moving image mode to perform moving image shooting. When the release button is pressed during moving image shooting and still image shooting is instructed, While the upper photoelectric conversion layer 31 is driven in the moving image mode, the lower photoelectric conversion layer 32 is driven in the still image mode to perform still image shooting. As a result, the digital camera 1 of the present embodiment can reduce the time lag from when the still image shooting is instructed until the actual still image shooting is actually performed, as compared with the conventional digital camera. In addition, it is possible to prevent frame dropping of moving images during still image shooting.

(2) In the digital camera 1, the upper photoelectric conversion layer 31 is composed of an organic photoelectric film, the lower photoelectric conversion layer 32 is composed of a photodiode, and the upper photoelectric conversion layer 31 is driven in a moving image mode, so that the lower photoelectric conversion layer 32 is driven. Was driven in still image mode. Since the photoelectric conversion layer composed of photodiodes has relatively low noise compared to the photoelectric conversion layer composed of organic photoelectric films, the output signal from the lower photoelectric conversion layer 32 can be used for still images in this way. , Still image noise can be reduced. Also, since noise is less noticeable in moving images than still images, it is preferable to use the output signal from the upper photoelectric conversion layer 31 for moving images in this way. Further, since the RGB image signal has good color reproducibility, the color reproducibility of a still image can be improved by using the RGB image signal output from the lower photoelectric conversion layer 32 in this way for a still image.

(3) In the digital camera 1, the long-time exposure control unit 112 performs the long-time exposure of the lower photoelectric conversion layer 32 based on the output signal from the upper photoelectric conversion layer 31 during the long-time exposure of the lower photoelectric conversion layer 32. The end timing of was decided. Thereby, even if the brightness of the photographing screen changes during long exposure, a long exposure image with an appropriate exposure amount can be obtained.

(4) In the digital camera 1, when the lower photoelectric conversion layer 32 is exposed for a long time, the display control unit 113 displays an image for display based on an output signal from the upper photoelectric conversion layer 31 on the liquid crystal monitor 15 as a through image. Displayed. This allows the user to confirm the shooting range even during long exposure shooting.

(Modification 1)
In situations where long exposure shooting is performed, the shooting screen may be dark. In such a case, in the above-described long exposure shooting mode, the through image based on the image signal from the upper photoelectric conversion layer 31 driven in the moving image mode becomes dark, which may be difficult for the user to see. Therefore, in such a case, it is possible to increase the gain of the image signal output from the upper photoelectric conversion layer 31 and increase the output value of the image signal so that a through image based on the image signal can be easily viewed. .

(Modification 2)
In the normal still image shooting mode, the digital camera 1 drives the upper photoelectric conversion layer 31 in the moving image mode and displays a through image on the liquid crystal monitor 15 based on an output signal from the upper photoelectric conversion layer 31. Good. When the release button is pressed, the lower photoelectric conversion layer 32 may be driven in the still image mode, and still image data based on the output signal from the lower photoelectric conversion layer 32 may be recorded in the memory card 17.

(Modification 3)
In the above-described embodiment, the exposure of the lower photoelectric conversion layer 32 is automatically terminated in the long-time exposure shooting. However, the present invention is not limited to this, and may be terminated according to the user's operation on the operation unit 13. When the preset exposure time has elapsed, the process may be terminated.

(Modification 4)
In the above-described embodiment, the upper photoelectric conversion layer 31 is driven in the moving image mode, and the lower photoelectric conversion layer 32 is driven in the still image mode. However, the present invention is not limited to this, and the upper photoelectric conversion layer 31 is driven in the still image mode. The lower photoelectric conversion layer 32 may be driven in the moving image mode.
