JP7171337B2 - IMAGING DEVICE, IMAGE RECORDING METHOD AND PROGRAM - Google Patents

Description

The present invention relates to an imaging device, an image recording method, and a program.

Conventionally, in order not to miss a photo opportunity, continuous shooting is performed before the continuous shooting instruction from the user (pre-continuous shooting), and continuous shooting is started from the captured images taken before the timing of the continuous shooting instruction. A method of recording as a photographed image is known. In addition, there is known a method of saving as one file when recording continuously shot images shot in this manner as a file on a medium.

When the continuously shot images are saved as one file, a main image, which is a representative image, is selected from the images, and the thumbnail of the main image is recorded in the header of the file. Thumbnails are used when displaying thumbnails on a playback device or the like. Japanese Patent Application Laid-Open No. 2002-200002 discloses a technique for recording a plurality of thumbnails in one file to solve the playback compatibility problem between playback devices.

Two patterns are conceivable as a method of saving continuously shot images as one file. One is a pattern (first mode) in which continuous shooting images obtained by one continuous shooting operation are saved as one file. In the first mode, when the continuous shooting operation is repeated several times, files for the number of repetitions are generated. The other is a pattern (second mode) in which repeated shooting operations are additionally saved in one file. In the second mode, one file remains even if the continuous shooting operation is repeated several times. In the second mode, a chapter is added to each continuous shooting unit so that editing operations such as frame deletion or replacement can be easily performed later, and operations can be performed collectively.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings.
(First embodiment)
FIG. 1 is a hardware configuration diagram of an imaging device 100 according to the first embodiment. Reference numeral 101 denotes a lens unit that causes an optical image of a subject to enter an imaging surface of an imaging device 102 . The lens unit 101 is composed of a fixed lens group for condensing light, a variable magnification lens group, an aperture, and a correction lens group. and perform the function of regulation.

The imaging device 102 is, for example, a CMOS (Complementary Metal Oxide Semiconductor) image sensor or the like, and converts incident light intensity into electric charge to generate an image signal. The imaging device 102 outputs an image signal of a predetermined number of pixels at arbitrary timing. In this embodiment, continuous shooting is performed. Therefore, the image sensor 102 outputs at a timing of, for example, 30 frames per second. A camera signal processing unit 103 performs predetermined processing on the image signal from the image sensor 102 and outputs image data. The resizing unit 116 converts an image signal having a predetermined number of pixels into an image signal having an arbitrary number of prime pixels. The resizing unit 116 converts, for example, an image signal having a predetermined number of pixels into an image signal having a thumbnail size of 160 horizontal pixels and 120 vertical pixels.

The compression/decompression unit 121 compresses and decompresses the image signal in an encoding format such as HEVC or JPEG. The recording/reproducing unit 104 records the image data compressed by the compression/decompression unit 121 on the recording medium 112 and reproduces the compressed image data recorded on the recording medium 112 . The recording/playback unit 104 manages image files recorded on the recording medium 112 according to a predetermined file system. As the container format of the image file, MPF format, MP4 format, or other containers may be applied.

The operation unit 107 is means for inputting an operation by the user, and the operation is input to the microcomputer 108 . An operation unit 107 includes a release button for instructing the start of pre-continuous shooting, the start and end of continuous shooting, a menu button for instructing setting changes, a status button for instructing status display, and the like.

A microcomputer 108 controls the entire imaging apparatus 100 . Note that the imaging device 100 may have a CPU instead of the microcomputer 108 . A ROM 109 stores programs executed by the microcomputer 108 and the like. A RAM 110 is a volatile memory used by the microcomputer 108 as a work area. The DRAM 111 is used to temporarily store image data to be processed by the camera signal processing unit 103 , resizing unit 116 , compression/decompression unit 121 and recording/reproducing unit 104 .

The camera signal processing unit 103 stores the developed image data in the DRAM 111 , and the resizing unit 116 resizes the developed image data in the DRAM 111 and stores the resized image data in the DRAM 111 . The compression/decompression unit 121 reads and compresses a series of image data stored in the DRAM 111 and writes back the compressed image data to the DRAM 111 . The recording/playback unit 104 sequentially reads the compressed image data from the DRAM 111 and records it on the recording medium 112 . At this time, if the writing back of the compressed image data to the DRAM 111 is performed earlier than the recording of the compressed image data from the DRAM 111 to the recording medium 112, the area of the DRAM 111 is exhausted, and the recording operation cannot be continued (buffer full). Become). A threshold is provided, and when the remaining amount of the DRAM 111 becomes less than the threshold before the area of the DRAM 111 is exhausted, it is determined that the buffer is full and the recording operation is stopped. In pre-continuous shooting, recording of compressed image data from the DRAM 111 to the recording medium 112 is not performed. Therefore, when a predetermined number of compressed image data are accumulated in the DRAM 111, the microcomputer 108 controls to discard the oldest data.

The output unit 117 outputs the video signal to the outside in a predetermined digital format such as an HDMI (registered trademark) signal or an SDI signal. A counter circuit 118 is a system counter of the imaging device 100 , and the imaging device 100 operates according to the output count value of the counter circuit 118 . For example, the camera signal processing unit 103 and the counter circuit 118 are synchronized with each other such that the count value is incremented by 1 each time the camera signal processing unit 103 outputs one frame of image data.

The display control unit 119 is means for controlling image display on the display unit 120 , and superimposes information such as various setting menus, titles and times on image data and causes the display unit 120 to display the information according to instructions from the microcomputer 108 . The display unit 120 has, for example, a liquid crystal panel, and displays images under the control of the display control unit 119 . A timer 115 is a real-time clock that manages the system time of the imaging device 100 . Bus 106 is used to transmit data and control signals between the above-described elements of imaging device 100 .

In the recording process in the imaging device 100, the user can set the compression mode including the compression rate of the compression/decompression unit 121 before recording is started. In the setting of recording continuous shot images, the compression/decompression unit 121 compresses the continuous shot images, and the recording/reproducing unit 104 records a continuous shot image file of the compressed image data on the recording medium 112 . In the recording standby state, the image sensor 102 converts an optical image from the lens unit 101 into an image signal, and the camera signal processing unit 103 converts the output image signal of the image sensor 102 into image data in a predetermined format and writes it to the DRAM 111 . The display control unit 119 reads the image data of the DRAM 111 and causes the display unit 120 to display the corresponding image. The microcomputer 108 starts the compression operation of the compression/decompression unit 121 and the recording operation of the recording/reproducing unit 104 in accordance with the user's pre-shooting start instruction and shooting start instruction from the operation unit 107 . The microcomputer 108 also stops the compression operation of the compression/decompression unit 121 and the recording operation of the recording/reproducing unit 104 in response to the user's shooting stop instruction from the operation unit 107 . The timer 115 measures the time related to the imaging apparatus 100 including the elapsed time since the operation unit 107 instructed to start shooting.

FIG. 2 is a flow chart showing image recording processing by the imaging device 100 . In S201, the microcomputer 108 determines whether or not a pre-continuous shooting start instruction has been received. The microcomputer 108 accepts a pre-continuous shooting start instruction when the user half-presses the release button of the operation unit 107 . Pre-continuous shooting is continuous shooting processing that is started prior to continuous shooting. If the microcomputer 108 receives a pre-continuous shooting start instruction (YES in S201), the process proceeds to S202. In S202, the microcomputer 108 generates a captured image and its thumbnail (reduced image). Specifically, the microcomputer 108 outputs an image signal from the image sensor 102, resizes it in the resizing unit 116, and compresses it in the compression/decompression unit 121 to obtain a captured image. Furthermore, the microcomputer 108 reduces the captured image to obtain a thumbnail. Next, in S203, the microcomputer 108 stores the captured image and thumbnail generated in S202 in the DRAM 111 as a buffer.

Next, in S204, the microcomputer 108 determines whether or not a continuous shooting start instruction has been received. The instruction to start continuous shooting is an instruction to start recording the captured images obtained by continuous shooting, and is an example of a recording instruction. The processing of S204 is an example of reception processing for receiving a recording instruction. The microcomputer 108 receives a continuous shooting start instruction when the user presses the release button of the operation unit 107 . If the microcomputer 108 receives the instruction to start continuous shooting (YES in S204), the process proceeds to S205. If the microcomputer 108 does not accept the instruction to start continuous shooting (NO in S204), the process proceeds to S202. In this case, the microcomputer 108 periodically repeats the processing of S202-S203.

In S<b>205 , the microcomputer 108 confirms the shooting mode set in the imaging device 100 . In the imaging device 100 of this embodiment, a first mode and a second mode can be set as the imaging mode. The first mode is a mode for creating a new image file for each continuous shooting when continuous shooting is repeated. That is, when continuous shooting is repeated three times, three image files are created. On the other hand, the second mode is a mode in which, when continuous shooting is repeated, images obtained by each continuous shooting are added to one image file. That is, when continuous shooting is started, one image file is created, and when continuous shooting is repeated three times thereafter, images are added to the already created image file. That is, the number of created image files is only one regardless of the number of times continuous shooting is repeated.

In the case of the first mode (YES in S205), microcomputer 108 advances the process to S206. In the case of the second mode (NO in S205), the microcomputer 108 advances the process to S207. In S206, the microcomputer 108 determines the captured image captured at the timing when the continuous shooting start instruction is accepted as the representative image of the image file. Then, the microcomputer 108 generates a thumbnail of the representative image and records it in the buffer as header information. The microcomputer 108 then advances the process to S208. In S207, the microcomputer 108 determines the captured image captured at the timing when the pre-continuous shooting start instruction is received as the representative image of the image file. Then, the microcomputer 108 generates a thumbnail of the representative image and records it in the buffer as header information. After that, the microcomputer 108 advances the process to S208.

In S<b>208 , the microcomputer 108 controls the recording/reproducing unit 104 to start writing from the DRAM 111 to the recording medium 112 . Next, in S209, the microcomputer 108 generates a captured image and its thumbnail. Next, in S210, the microcomputer 108 stores the captured image and thumbnail generated in S209 in the buffer. Next, in S211, the microcomputer 108 determines whether or not a continuous shooting end instruction has been received. Here, the continuous shooting end instruction is an example of the recording end instruction. When the user releases the release button, the microcomputer 108 accepts a continuous shooting end instruction. If the microcomputer 108 receives the continuous shooting end instruction (YES in S211), the process proceeds to S212. If the microcomputer 108 does not accept the continuous shooting end instruction (NO in S211), the process proceeds to S209. In this case, the microcomputer 108 records frames by periodically repeating S209 to S210.

In S212, the microcomputer 108 reads the captured image, thumbnail and header information remaining in the DRAM 111 as a buffer, generates an image file containing them, and stores it in the recording medium 112. FIG. This completes the recording process. Note that the thumbnail corresponds to the captured image determined as the representative image of the image file, and the process of S212 is the control process for controlling the captured image determined as the representative image to be recorded in the image file as the representative image. An example.

FIG. 3 is a diagram showing an example of an image file. Continuous frames 300 shown in FIG. 3A are frames that are generated from the timing at which the pre-continuous shooting start instruction is accepted to the timing at which the continuous shooting end instruction is accepted, and which are temporarily stored in the buffer. The microcomputer 108 appropriately discards frames older than a predetermined time from the buffer between the pre-continuous shooting start instruction and the continuous shooting start instruction. Then, when the microcomputer 108 receives the continuous shooting start instruction, it determines the frames to be recorded as the image file. In this embodiment, it is assumed that frames older than 5 frames are discarded from the buffer. Also, in FIG. 3, an example will be described in which a continuous shooting start instruction is received at the timing when frame 5 is generated, and frames 1 to 9 are recorded as an image file.

An image file 310 in FIG. 3B is an image file created in the first mode. In the first mode, the captured image generated at the timing of the continuous shooting start instruction, that is, the captured image of frame 5 is determined as the representative image. Then, the thumbnail of the representative image is written to the image file as header information. An image file 320 in FIG. 3(c) is an image file created in the second mode. In the second mode, the captured image generated at the timing of pre-continuous shooting, that is, the captured image of frame 1 is determined as the representative image. Then, the thumbnail of the representative image is written to the image file as header information. In this way, in the image file 320, since frames are additionally written in units of chapters corresponding to continuous shooting, editing in units of chapters can be easily performed.

As described above, the imaging apparatus 100 of the first embodiment records the captured image at the timing of starting continuous shooting as the representative image of the image file in the first mode, and records the pre-continuous shooting in the second mode. The photographed image at the timing of the start of photography is recorded as a representative image. In this way, the imaging device 100 can record representative images suitable for image files.

Image files generated in the first mode are used such that the user selects a desired image file by displaying a list of thumbnails thereof. For this reason, it is desirable that the displayed thumbnails correspond to the captured images obtained at the timing when the user started continuous shooting. In response to this, in the first mode, the imaging apparatus 100 records the thumbnail of the captured image at the timing of starting continuous shooting as a representative image, so that the thumbnail at the timing of starting continuous shooting can be displayed. Therefore, the user can specify the desired image file from the thumbnails without any sense of incongruity.

Also, the image file generated in the second mode is edited such as deletion or replacement in units of chapters, which are units of continuous shooting. Therefore, it is desirable to use an image representing a plurality of chapters as the representative image of the image file. Correspondingly, in the second mode, the imaging apparatus 100 records the thumbnail of the captured image at the timing of starting pre-continuous shooting as a representative image. Therefore, the user can easily identify an image file containing multiple chapters.

A first modification will be described. In this embodiment, in the second mode, the captured image at the timing of starting pre-continuous shooting, that is, the thumbnail corresponding to the oldest captured image among the captured images included in the image file is used as the representative image. However, the image capturing apparatus 100 may determine, as a representative image, a thumbnail corresponding to a captured image captured before the timing of the continuous shooting start instruction, and is not limited to the oldest captured image.

A second modification will be described. The imaging apparatus 100 may be controlled so as to record the captured image at the timing corresponding to each mode as the representative image, and the specific recording method is not limited to the embodiment. As another example, the imaging device 100 may write identification information of the captured image as the representative image as header information instead of the thumbnail.

(Second embodiment)
Next, the imaging device 100 according to the second embodiment will be mainly described in terms of differences from the imaging device 100 according to the first embodiment. In a case where a photo opportunity has come and the photo opportunity has ended soon after, the user performs a user operation to end continuous shooting immediately after performing a user operation to start continuous shooting. In such a case, even in the first mode, the imaging apparatus 100 of the present embodiment records, as a representative image, the thumbnail at the start of pre-continuous shooting instead of the thumbnail at the start of continuous shooting.

FIG. 4 is a flowchart showing image recording processing by the imaging device 100 according to the second embodiment. The processing of S401 to S405 is the same as the processing of S201 to S205 described with reference to FIG. In S405, if the microcomputer 108 is in the first mode (YES in S405), the process proceeds to S406. In the case of the second mode (NO in S405), the microcomputer 108 advances the process to S408. In step S<b>406 , the microcomputer 108 determines the captured image captured at the timing of receiving the continuous shooting start instruction as the representative image of the image file. Then, the microcomputer 108 generates a thumbnail of the representative image and records it in the buffer as header information. This process is the same as the process of S206. Next, in S407, the microcomputer 108 generates a thumbnail of the captured image captured at the timing when the pre-continuous shooting start instruction is received, and saves the generated thumbnail in the buffer. The microcomputer 108 then advances the process to S409.

In S408, the microcomputer 108 determines the captured image captured at the timing when the pre-continuous shooting start instruction is accepted as the representative image of the image file. Then, the microcomputer 108 generates a thumbnail of the representative image and records it in the buffer as header information. After that, the microcomputer 108 advances the process to S409. The processing of S409-S412 is the same as the processing of S208-S211. In S412, if the microcomputer 108 accepts a continuous shooting end instruction (YES in S412), the process proceeds to S413.

In S413, the microcomputer 108 determines whether or not the continuous shooting time is less than the first time. Here, the continuous shooting time is the time from the timing at which the continuous shooting start instruction is accepted to the timing at which the continuous shooting end instruction is accepted, and is an example of the recording time. The first time is a predetermined time. If the time is less than the first time (YES in S413), microcomputer 108 advances the process to S414. If the time is equal to or longer than the first time (NO in S413), the microcomputer 108 advances the process to S417.

In S414, the microcomputer 108 determines whether or not the pre-continuous shooting time is less than the second time. Here, the pre-continuous shooting time is the time from the timing at which the pre-continuous shooting start instruction is accepted to the timing at which the continuous shooting start instruction is accepted. The second time is a predetermined time. If the time is less than the second time (YES in S414), microcomputer 108 advances the process to S415. If the time is longer than or equal to the second time (NO in S414), the microcomputer 108 advances the process to S415. In S415, the microcomputer 108 confirms the recording mode. If the recording mode is the first mode (YES in S415), the microcomputer 108 advances the process to S416. If the recording mode is the second mode (NO in S415), the microcomputer 108 advances the process to S417.

In S416, the microcomputer 108 regenerates the header information using the thumbnail at the timing of the pre-continuous shooting start instruction recorded in the buffer in S407. The microcomputer 108 then advances the process to S417. In S 417 , the microcomputer 108 reads the captured image, thumbnail and header information remaining in the DRAM 111 as a buffer, generates an image file containing them, and stores it in the recording medium 112 . Note that the processing of S417 is the same as the processing of S212.

As described above, even when the imaging apparatus 100 according to the second embodiment is set to the first mode, the continuous shooting time is less than the first time and the pre-continuous shooting time is equal to or longer than the second time. In the case of , the captured image at the timing of starting pre-continuous shooting is determined as the representative image. Other configurations and processes of the imaging apparatus 100 according to the second embodiment are the same as those of the imaging apparatus 100 according to the first embodiment.

As described above, in the second embodiment, when the continuous shooting time is less than the first time period and the pre-continuous shooting time period is equal to or longer than the second time period, the imaging apparatus 100 starts pre-continuous shooting. A photographed image of timing is recorded as a representative image. As a result, an image captured at a timing close to the photo opportunity can be used as the representative image of the image file. Further, when the pre-continuous shooting time is less than the second time, the imaging apparatus 100 records the captured image at the timing of starting continuous shooting as the representative image. This is because it is considered that the user is performing an operation similar to single shooting.

A modification of the second embodiment will be described. In the first mode, the imaging apparatus 100 determines the captured image at the start timing of the pre-continuous shooting as the representative image when the continuous shooting time is less than the first time regardless of the pre-continuous shooting time. good too.

In the above-described embodiment, in the second mode, when continuous shooting is repeatedly performed, the image data of the repeated continuous shooting is added to one file. However, the second mode is not limited to this, and may be a mode in which only the image at the timing when the release button is fully pressed is recorded instead of continuous shooting. For example, after pressing the release button halfway, pre-shooting is performed, the pre-shooting images taken before the release button is fully pressed and recording instructions are recorded, and the pre-shooting instructions and the pre-shooting images recorded by the recording instruction are recorded. , a mode in which data is recorded by appending to a specific file. Here, the specific file is assumed to be a file corresponding to the second mode.

Although the present invention has been described in detail based on its preferred embodiments, the present invention is not limited to these specific embodiments, and various forms without departing from the gist of the present invention can be applied to the present invention. included. Some of the above-described embodiments may be combined as appropriate.

In addition, when a software program that implements the functions of the above-described embodiments is supplied directly from a recording medium or via wired/wireless communication to a system or apparatus having a computer capable of executing the program, and the program is executed. is also included in the present invention.

Therefore, in order to implement the functional processing of the present invention in a computer, the program code itself supplied and installed in the computer also implements the present invention. In other words, the present invention also includes the computer program itself for realizing the functional processing of the present invention. In that case, as long as it has the function of a program, the form of the program, such as an object code, a program executed by an interpreter, or script data supplied to the OS, does not matter.
