  The present invention relates to an imaging apparatus and a control method thereof.

  2. Description of the Related Art In recent years, some imaging apparatuses such as digital cameras and digital video cameras that record captured image data on a storage medium have a simultaneous recording function that performs still image shooting in parallel with moving image shooting. In the above-described imaging device, when still image shooting is performed in parallel with moving image shooting, the flash data at the time of still image shooting may affect moving image data. For example, as an influence on moving image data, information such as white balance and exposure value in moving image shooting may be significantly changed by flash emission.

  However, the above-described conventional technology needs to include a plurality of image sensors for moving image shooting, still image shooting, and the like, and is not a preferable configuration in terms of cost in Ichii, where price competition is intense. In addition, in the related art, when still image shooting is performed during moving image shooting in a low illumination environment, the frame rate may not be maintained. For example, when still image shooting is performed during moving image shooting with an exposure period of 1/30 seconds, the frame rate of 30 frames / second cannot be maintained due to lack of moving image data corresponding to the exposure period of still image shooting. . As a result, a smooth moving image cannot be obtained.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to the following embodiments. The embodiment of the present invention shows the most preferable mode of the invention and does not limit the scope of the invention.

  First, the configuration of the imaging apparatus according to the present embodiment will be described in detail with reference to FIG. Here, FIG. 1 is a block diagram schematically illustrating the configuration of the imaging apparatus 1.

  As shown in FIG. 1, the imaging apparatus 1 includes an imaging unit 101, an image processing unit 102, a memory 103, a compression / decompression processing unit 104, a recording / playback control unit 105, a recording medium 106, a CPU 107, an operation input unit 108, a strobe. A control unit 109 and a strobe light emitting unit 110 are provided.

  The imaging unit 101 includes an imaging lens, an imaging device for photoelectrically converting the formed image, an A / D conversion processing unit that converts an analog image signal read from the imaging device into a digital image signal, and the like. The image processing unit 102 generates a luminance signal and a color difference signal based on the image signal read from the imaging unit 101 and writes the data to the memory 103. The memory 103 is a RAM (Random Access Memory) or the like, and stores data in a readable / writable manner.

  When data is recorded, the compression / decompression processing unit 104 reads out the image processed image data from the memory 103, compresses the image data using a predetermined compression method, and writes the compressed data back to the memory 103. As a compression method, there is a JPEG method for still image data, and MPEG-2 for moving image data. Here, JPEG is an abbreviation for Joint Photographic Experts Group. MPEG-2 is an abbreviation for Moving Picture Experts Group phase 2. Further, the compression / decompression processing unit 104 performs decompression processing according to the compressed data read from the memory 103 when data is reproduced, and writes the decompressed data back to the memory 103.

  The recording / reproduction control unit 105 performs control related to data recording on the recording medium 106 or data reproduction from the recording medium 106. Specifically, the recording / reproduction control unit 105 records the compressed data read from the memory 103 on the recording medium 106 at the time of data recording. The recording / reproduction control unit 105 controls to read data from the recording medium 106 and write the read data to the memory 103 during data reproduction. The recording medium 106 may be a magnetic tape, an optical disk, a semiconductor memory, or the like. Note that the recording / reproduction control unit 105 and the recording medium 106 may be configured by a plurality of recording media. For example, the recording medium for still image recording / reproduction and the recording medium for moving image recording / reproduction may be separated.

  A CPU 107 (Central Processing Unit) as a control unit controls the entire imaging apparatus 1. Specifically, the imaging apparatus 1 expands program data stored in a ROM (Read Only Memory) or the like in a work area of an internal RAM (none of which is specifically shown), and the expanded program data and the CPU Centrally control each department through collaboration. That is, the CPU 107 performs overall control of each unit by sequentially executing the program data stored in the ROM.

  The operation input unit 108 is a button or switch provided on the housing of the imaging apparatus 1. The operation input unit 108 receives an operation input from the user via the buttons and switches described above, and outputs an operation signal corresponding to the received operation input to the CPU 107. For example, the operation input unit 108 receives an operation input such as an instruction to start or end moving image shooting or a still image shooting instruction (including moving image shooting) from the user. That is, the operation input unit 108 receives an input of a still image shooting instruction during acquisition of moving image data at the time of moving image shooting.

  The strobe light control unit 109 is configured to turn on / off the strobe light emission switch of the operation input unit 108 or output a signal from a light receiving element (not shown) that detects the amount of light from the subject during still image shooting. 110 performs light emission control. For example, when detecting the amount of light by TTL (Through The Lens), the strobe control unit 109 determines whether or not the subject is in a low illumination environment based on the amount of light from the subject measured through the photographing lens. When the strobe control unit 109 determines that the environment is a low illuminance environment, the strobe control unit 109 controls the subject to emit auxiliary light from the strobe light emitting unit 110. When performing TTL dimming, the strobe control unit 109 may control to integrate the amount of light from the subject and stop the light emission of the strobe light emitting unit 110 when the integrated value reaches a predetermined threshold value. .

  A strobe light emitting unit 110 serving as a light emitting unit emits auxiliary light to a subject during an exposure period for still image shooting or moving image shooting. The strobe light emitting unit 110 may have any configuration as long as it has a light source that emits auxiliary light to the subject, such as a xenon tube or a white light emitting diode.

  Next, details of the imaging unit 101 will be described with reference to FIG. Here, FIG. 2 is a block diagram illustrating details of the imaging unit 101.

  As illustrated in FIG. 2, the imaging unit 101 includes a photographic lens 501, an imaging element 502, an ADC 503, a selector 504, memories 505 and 506, and a selector 507.

  The photographing lens 501 forms a subject image on the imaging surface of the image sensor 502. The image sensor 502 photoelectrically converts the subject image formed by the photographing lens 501. An ADC 503 (Analog-to-Digital Converter) converts analog image data read from the photographing lens 501 into digital image data.

  The selector 504 selects and outputs one or more output destinations of digital image data input from the ADC 503 under the control of the CPU 107. Specifically, the selector 504 outputs the digital image data M1 when the input digital image data is odd field data obtained by reading out the odd lines of the photographing lens 501. In the following description, the odd field is referred to as the first field, and the odd field data is referred to as the first field image data.

  The selector 504 outputs the digital image data M2 when the input digital image data is even field data obtained by reading an even line of the photographing lens 501. In the following description, the even field is called the second field, and the even field data is called the second field image data. The selector 504 outputs the digital image data M3 when the input digital image data is still image data obtained by still image shooting.

  The memory 505 stores the digital image data M1 output from the selector 504, that is, the first field image data read from the photographing lens 501. The memory 506 stores the digital image data M2 output from the selector 504, that is, the second field image data read from the photographing lens 501.

  The selector 507 selects either the memory 505 or the memory 506 under the control of the CPU 107, reads out the image data from the selected memory, and outputs it. The CPU 107 controls the output order and the number of outputs of the first field image data or the second field image data in the selector 507. Accordingly, the selector 507 is moving image data generation means for alternately generating the first field image data or the second field image data.

  The first field image data or the second field image data output from the selector 507 is input to the moving image processing unit 102a of the image processing unit 102, and image processing as a moving image is performed. For example, the moving image processing unit 102a performs image processing for generating moving image data that uses the input first and second field image data as a set of frames.

  Also, the digital image data M3 obtained by taking a still image output from the selector 504 is input to the still image processing unit 102b of the image processing unit 102, and image processing as a still image is performed. For example, the still image processing unit 102b performs image processing such as gradation conversion, color conversion, and sharpening processing in addition to generation of luminance signals and color difference signals.

  Here, an operation performed at the time of moving image shooting or still image shooting under the control of the CPU 107 in the imaging unit 101 described above will be described. First, the operation during moving image shooting will be described.

  When the moving image shooting is started, the CPU 107 sequentially acquires moving image data corresponding to the moving image reproduction rate by sequentially driving the image sensor 502 in a predetermined exposure period. For example, when the reproduction rate of a moving image is 30 fps (Frame Per Second), the first field image and the second field image constituting each frame are captured at 1/60 sec.

  However, in the case of moving image shooting under a low illumination environment, the image capturing for each field image may be underexposed. In this way, when the field-by-field image is underexposed, the exposure period per time is set longer, and for example, an image for one frame is captured at 1/30 sec. That is, in a low illuminance environment or the like, the first field image and the second field image constituting one frame may be captured in one exposure period. In the following description, setting a long exposure period, such as performing moving image shooting with the exposure period of one frame described above, is called slow shutter shooting, and is distinguished from normal moving image shooting.

  Next, the CPU 107 reads out image data of either the first field image or the second field image from the image data captured by the image sensor 502. When the CPU 107 reads the odd lines of the image sensor 502 and acquires the first field image data, the CPU 107 stores the acquired data in the memory 505 using the output of the selector 504 as the digital image data M1. Further, when the CPU 107 reads the even lines of the image sensor 502 and acquires the second field image data, the CPU 107 stores the acquired data in the memory 506 with the output of the selector 504 as the digital image data M2. Next, the CPU 107 sequentially outputs the first field image data or the second field image data to the moving image processing unit 102a by alternately performing switching in the selector 507.

  That is, the selector 507 that operates under the control of the CPU 107 described above is an image data generation unit. For example, in normal moving image shooting in which each field image is captured, either the first field image data or the second field image data is acquired by the selector 507, and a moving image is generated. In addition, in slow shutter photography in which the exposure period is one frame, both the first field image data and the second field image data are alternately acquired by the selector 507 from one image captured in the exposure period. A moving image is generated.

  Next, the operation during still image shooting will be described. When still image shooting is started and image pickup is performed by the image sensor 502, the CPU 107 outputs the output of the selector 507 to digital image data so that the image data read from the image sensor 502 is output to the still image processing unit 102b. Let it be M3.

  Note that the above-described operation during still image shooting is performed by interrupting the moving image shooting when the moving image shooting is in progress. When still image shooting with strobe light emission is performed during moving image shooting, the output of image data captured by still image shooting is only digital image data M3 by the selector 504. Therefore, the data in the memory 505 and the memory 506 is not updated by image data captured with strobe light emission. In addition, the field image data that is alternately read and output from the selector 507 during the period interrupted by the still image shooting is image data captured immediately before the still image shooting. Note that in the case of still image shooting without strobe light emission, the digital image data M3 and the digital image data M1 or the digital image data M2 are output by the selector 504. Therefore, in still image shooting without strobe light emission during moving image shooting, image data captured by the still image shooting is used as moving image data.

  Next, a process performed under the control of the CPU 107 and a process flow from the start to the end of moving image shooting of the imaging apparatus 1 will be described with reference to FIGS. In the following description, one exposure period is 1/30 sec, and it will be described as slow shutter shooting in which one frame of moving image is shot in one exposure period. FIG. 3 is a flowchart showing processing from the start to the end of moving image shooting of the imaging apparatus 1. 4 and 5 are timing charts illustrating the operation of the imaging apparatus 1 during moving image and still image shooting.

  As illustrated in FIG. 3, the CPU 107 drives the imaging unit 101 based on an operation instruction from the operation input unit 108 and starts moving image shooting with slow shutter shooting (S <b> 1). Next, the CPU 107 determines whether or not a moving image shooting end instruction is input from the operation input unit 108 during moving image shooting with slow shutter shooting (S2) (S3). If it is determined in S3 that the moving image shooting end instruction has been input, the CPU 107 ends moving image shooting (S9).

  If it is determined in S3 that no moving image shooting end instruction has been input, the CPU 107 determines whether a still image shooting instruction has been input from the operation input unit 108 (S4). If it is determined in S4 that a still image shooting instruction has not been input, the CPU 107 returns to S2 to continue moving image shooting. That is, in the imaging apparatus 1, moving image shooting is continued until a moving image shooting end instruction or a still image shooting instruction is input from the operation input unit 108.

  If it is determined in S4 that a still image shooting instruction has been input, the CPU 107 determines whether there is an instruction from the operation input unit 108 or a light emission instruction of the strobe light emitting unit 110 by light emission control of the strobe control unit 109 (S5). That is, S5 as determination means determines whether or not the strobe light emitting unit 110 emits light during the exposure period for still image shooting. If it is determined in S5 that there is no light emission instruction, the CPU 107 interrupts the moving image shooting for still image shooting without strobe light emission (S6). In still image shooting without strobe light emission, as described above, image data at the time of still image shooting is used as moving image data.

  If it is determined in S5 that there is a light emission instruction, the CPU 107 performs still image shooting with strobe light emission of the strobe light emitting unit 110 while interrupting moving image shooting (S7). The still image shooting in S7 is shot at 1/60 sec, which is shorter than 1/30 sec, which is one exposure period, because sufficient brightness can be obtained by flash emission. In S7, which is the first control step, the moving image data related to the period during which moving image shooting is interrupted is generated by selecting and reading the data stored in the memories 505 and 506 of the imaging unit 101 described above with the selector 507. . That is, in S7, the shooting is interrupted in the still image shooting by the first field image data or the second field image data acquired and acquired immediately before the shooting of the still image so that the moving image data is not lost due to the interruption of the shooting of the moving image by the still image shooting. Movie data relating to the selected period is generated.

  In the generation of the moving image data related to the period interrupted in the still image shooting in S7, the moving image generated from one image according to the length of the exposure period for moving image shooting with respect to the length of the period interrupted in the still image shooting The number of data generations is different. As exemplified in the present embodiment, when the exposure period for moving image shooting is 1/30 sec and the period interrupted by still image shooting is 1/60 sec, either the first field image or the second field image is selected. Will be generated. That is, in S7, moving image data for a period related to the field image corresponding to the period interrupted by the still image shooting is generated.

  Next, the CPU 107 controls to shift the acquisition order from the memories 505 and 506 in the selector 507 after complementing in S7 by a half period (1/60 sec) of the exposure period in moving image shooting (S8). That is, in S8, which is the second control step, the CPU 107 controls the generation order so that the first field image and the second field image are alternately generated before and after the interruption period due to still image shooting. Therefore, in moving image shooting after still image shooting, the switching order of the selector 507 per one exposure period is changed, and the generation order of the first and second field images is changed.

  Here, the operation at the time of moving image and still image shooting at the timing illustrated in FIGS. As shown in FIG. 4, the exposure periods R1, R2, R4, and R5 during slow shutter photography are 1/30 sec.

  The frame F1 is generated by the image data MD11 and the image data MD21 acquired by exposure in the exposure period R1. Similarly, the frame F2 is generated by the image data MD12 and the image data MD22 acquired by exposure in the exposure period R2. That is, the imaging apparatus 1 forms a frame by acquiring the first field image and the second field image from one piece of image data captured during an exposure period of 1/30 sec.

  Next, in the imaging apparatus 1, still image shooting with strobe light emission during moving image shooting is performed in the exposure period R3 at the timing of the strobe light emission signal ST1. The exposure period R3 is 1/60 sec shorter than the slow shutter shooting, but still image data SD1 having sufficient brightness can be acquired by flash emission. The image data acquired in the exposure period R3 becomes image data having a brightness different from that at the time of moving image shooting by strobe light emission. Accordingly, the image data captured in the exposure period R3 is not used as moving image data. Instead, the selector 507 obtains the image data MD13 captured in the exposure period R2 immediately before the flash emission and stored in the memory 505 as moving image data related to the exposure period R3.

  Image data captured in the exposure period R4 is acquired in the order of the image data MD23 and the image data MD14 by the image data MD13 acquired along with the still image shooting. In other words, the generation order of the first field image and the second field image after the still image shooting is shifted by a half cycle due to the still image shooting with strobe light emission during the moving image shooting.

  Similarly, a case where still image shooting with strobe light emission during moving image shooting is performed with a half-cycle shift is as shown in FIG. As shown in FIG. 5, the image data captured in the exposure period R6 is the image data MD25 of the frame F5 and the image data MD16 of the frame F6. The image data captured in the exposure period R7 is the image data MD26 and the image data MD17 of the frame F6.

  In the imaging device 1, at the timing of the strobe light emission signal ST2, still image shooting with strobe light emission during moving image shooting is performed in the exposure period R8. The moving image data related to the exposure period R8 is generated by the data stored in the memory 506 by the selector 507, and thus becomes the same image data MD27 as the image data MD26 imaged in the exposure period R7 immediately before the strobe light emission. By generating the image data, the image data captured in the exposure period R9 is generated in the order of the image data MD18 and the image data MD28 of the frame F8. That is, due to still image shooting with strobe light emission during moving image shooting, the generation order shifted by a half cycle before the still image shooting becomes the normal generation order.

  As described above, the imaging apparatus 1 has a configuration in which, when a still image shooting instruction is given during moving image shooting, the moving image shooting is interrupted, the still image shooting is performed, and the moving image shooting is resumed after the still image shooting ends. Therefore, in the imaging apparatus 1, it is not necessary to provide an imaging element for moving image shooting and an imaging element for still image shooting, and it is possible to perform moving image shooting and still image shooting at low cost.

  Further, in the imaging apparatus 1, the CPU 107 controls the selector 507 so that the first field image data and the second field image data are alternately obtained as moving image data from one image captured during the exposure period for moving image shooting. And at least one is produced | generated. The CPU 107 controls the generation order and number of the first field image data and the second field image data in the selector 507. Further, the CPU 107 generates from one image according to the length of the exposure period for moving image shooting with respect to the interruption period so that the moving image data corresponding to the interruption period of moving image shooting by still image shooting is not lost. Controls the number of video data generated. Further, the CPU 107 controls the generation order so that the first field image data and the second field image data are alternately generated before and after the interruption period of moving image shooting by still image shooting.

  For this reason, the imaging apparatus 1 supports a period of interruption of moving image shooting due to still image shooting even when still image shooting is performed during moving image shooting with slow shutter shooting in a low-light environment. No video data is lost. In addition, the imaging device 1 alternately generates the first field image data and the second field image data before and after the period of interruption of moving image shooting by still image shooting. Therefore, the imaging apparatus 1 can acquire smooth moving image data.

  Further, the imaging apparatus 1 performs control by the CPU 107 described above during still image shooting with strobe light emission during moving image shooting. Therefore, the imaging apparatus 1 can acquire smoother moving image data without using image data with different brightness due to strobe light emission as moving image data.

  Note that the description in the above-described embodiment shows an example, and the present invention is not limited to this. The configuration and operation in the embodiment described above can be changed as appropriate.

  For example, the moving image data related to the interruption period of moving image shooting by still image shooting may be generated by data immediately after still image shooting, in addition to the data immediately before the still image shooting. In other words, the generation of the moving image data related to the interruption period due to the still image shooting may be image data captured during the most recent exposure period of the still image shooting. Specifically, the first field image or the second field image may be selected and acquired by the selector 507 from the image data captured in the exposure period immediately after the still image shooting. Further, the data immediately before the still image shooting and the data immediately after the still image shooting may be combined to generate the moving image data related to the interruption period due to the still image shooting.

  In the present embodiment, the exposure period during slow shutter photography has been described as 1/30 sec. However, the exposure period is not particularly limited to 1/30 sec. For example, as in the case of recording 15 fps moving image data, one exposure period may be 1/15 sec.

  Further, in this embodiment, the exposure period of still image shooting that is interrupted during moving image shooting is set to the exposure period (1/60 sec) for one field, but is not particularly limited to that exposure period. For example, the exposure period for still image shooting may be the same exposure period for one frame as the exposure period for moving image shooting. However, if the exposure period for still image shooting coincides with the exposure period for moving image shooting, it is not necessary to shift the acquisition order of the first field image and the second field image after still image shooting in S8. In other words, the acquisition order in S8 may be changed only when the period during which moving image shooting is interrupted by still image shooting and the length of the exposure period during moving image shooting do not substantially match.
