(Digital camera configuration)
FIG. 5 is a block diagram illustrating an example of a functional configuration of the digital camera. 6A and 6B are diagrams showing an example of the appearance of the digital camera. FIG. 6A is a diagram seen from the front, and FIG. 6B is a diagram seen from the back. The configuration of the digital camera other than the battery lid will be described below with reference to FIGS.

  A CCD (Charge Coupled Device) 420 in FIG. 5 is an imaging unit that images an object scene and generates an electronic image signal, and has, for example, 1600 × 1200 pixels. The CCD 420 converts the light image of the subject formed by the imaging lens 410 into R (red), G (green), and B (blue) color component image signals (pixel signals received by each pixel) for each pixel. A signal comprising a signal string) and output.

  An image signal (analog signal) obtained from the CCD 420 is supplied to the analog signal processing circuit 430. The analog signal processing circuit 430 is a circuit that performs predetermined analog signal processing on the image signal. The analog signal processing circuit 430 includes at least a correlated double sampling circuit (Correlated Double Sampling: CDS, not shown) and an auto gain control (AGC, not shown) circuit. Noise reduction processing of the image signal is performed by the correlated double sampling circuit, and the level of the image signal is adjusted by adjusting the gain by the auto gain control circuit.

  The A / D converter 440 converts each pixel signal of the image signal into, for example, a 12-bit digital signal. The converted digital signal is given to a central processing unit (CPU) 450 and temporarily stored in a RAM (Random Access Memory) 460 as image data. The image data stored in the RAM 460 is subjected to color correction processing and the like by the image processing unit 480 and then subjected to compression processing and the like by the compression / decompression unit 490.

  In addition, an audio signal obtained from the microphone 500 is input to the audio processing unit 510. The audio signal input to the audio processing unit 510 is converted into a digital signal by an A / D converter (not shown) provided in the audio processing unit 510 and temporarily stored in the RAM 460. The digitized audio signal is sent again to the audio processing unit 510 and can be reproduced from the speaker 502.

  The operation unit 520 includes a power button 520A, various operation buttons 520B, a shutter release button 520C, and the like, and is used when a user changes the setting of the digital camera 100 or performs an imaging operation.

  The battery 108 is a power supply source for the digital camera 100. For this, a secondary battery such as a lithium ion battery may be used.

  The real time clock 540 is used to acquire the current time, and is used to acquire the imaging date and time necessary for imprinting the date on the image.

  The CPU 450 performs overall control of the above-described units by executing predetermined programs recorded in a RAM 460 and a ROM (Read Only Memory) 550. The RAM 460 is a high-speed accessible semiconductor memory, and the ROM 550 is configured as a non-volatile semiconductor memory (for example, a flash ROM) that cannot be electrically rewritten. A part of the area in the RAM 460 functions as a temporary storage buffer area, and temporarily stores image data and audio data.

  The CPU 450 includes an image processing unit 480, a compression / decompression unit 490, and an audio processing unit 510. Each of these processing units 480, 490, 510 is a functional part realized by the microcomputer executing a predetermined program.

  The image processing unit 480 is a processing unit that performs various digital image processing such as WB (white balance) processing and γ correction processing. The WB process is a process of adjusting the color balance by performing level conversion of each of R, G, and B color components, and the γ correction process is a process of correcting the gradation of the pixel data. The compression / decompression unit 490 further compresses the image data that has been subjected to the color correction processing and the like by the image processing unit 480. As the compression method, for example, a JPEG (Joint Photographic Experts Group) method or the like is adopted. The audio processing unit 510 is a processing unit that performs various digital processes on audio data.

  The CPU 450 having such a configuration performs processing in an imaging mode and a reproduction mode. For example, in the imaging mode, first, the CCD 420 is set to an operation mode for viewfinder (LCD 610) image output, imaging is performed at a predetermined cycle (for example, 30 frames / second), and image data corresponding to the imaging is sequentially output. (Preliminary imaging). The image data output from the CCD 420 is displayed as a viewfinder image on the LCD 610 via the analog signal processing circuit 430, the A / D converter 440, and the image processing unit 480. In this state, when the shutter release button 520C is half-pressed (preliminary imaging) by the user, the CPU 450 determines an AE (Auto Exposure) evaluation value and AF (Auto Focus) based on image data of preliminary imaging input from the CCD 420. Obtain an evaluation value. The CPU 450 obtains the in-focus position based on the AF evaluation value by a known hill-climbing method, for example, and moves the imaging lens 410 to the in-focus position using the AE / AF unit 560. Further, the CPU 450 determines a shutter speed (charge accumulation time in the CCD 420) at the time of actual imaging, an aperture value of the imaging lens 410, and a gain value of auto gain control in the analog signal processing circuit 430 based on the AE evaluation value.

  When the shutter release button 520C is fully pressed (main image pickup) in the image pickup mode, the CPU 450 sets the operation mode of the CCD 420 to the operation mode for main image pickup, picks up the subject, and takes image data acquired by the CCD 420. Based on the above, the compression / decompression unit 490 generates a compressed image. The compressed high-resolution image data is recorded on the micro SD card 110 that is a recording medium. The data structure in the micro SD card 110 will be described below.

  The micro SD card 110 stores still images and moving images recorded by the digital camera 100 in sequence. Each frame stores file attributes, tag information, and high-resolution image data (1600 × 1200 pixels) compressed in JPEG format. In this file attribute AT (ATtribute), a read-only attribute (R), an archive attribute (A), a system file attribute (S), and a hidden file attribute (H) can be set.

  In the tag information, a file name, an imaging date and time, a serial number of a digital camera used for imaging, and information on an audio file associated with the image data are recorded. This imaging date and time is recorded on the micro SD card 110 based on timekeeping information at the time of imaging in the real-time clock 540, and is used for imprinting settings and the like.

  A card interface (card I / F) 580 is an interface for writing and reading image data to and from the micro SD card 110 attached to the micro SD card connection unit 52.

  As already described with reference to FIG. 1, the battery cover 102 is connected to the memory card conversion adapter 112 for mounting the micro SD card 110 and converting it into the contact portion shape of the SD card, or the storage portion for connecting the SD card itself. 114.

  At the time of reading / writing image data to / from the micro SD card 110, the compression / decompression unit 490 performs compression processing of the image data, for example, in JPEG format, and the image data is transmitted / received via the card interface 580 between the RAM 460 and the micro SD card 110. Is done. In addition, audio data is transmitted and received between the RAM 460 and the micro SD card 110 via the card interface 580 even when audio data is read and written.

  Furthermore, the digital camera 100 can use this card interface 580 not only to transmit and receive data such as images and sounds, but also to import programs that are operated by the digital camera 100. For example, a control program recorded on the micro SD card 110 can be taken into the RAM 460 or the ROM 550 via the CPU 450. Thereby, the control program can be updated.

  The flash 590 is a light emitting device that emits photographing auxiliary light and irradiates a subject in a state where light emission is permitted. The self-timer lamp 600 is a lamp that blinks when the self-timer is activated.

  An LCD (Liquid Crystal Display) 610 is a display device that displays an object scene, displays various menus for the user, and provides information for operation.

  The digital camera 100 is further provided with a USB (Universal Serial Bus) terminal 620, and a memory and other peripheral devices compatible with the USB standard can be connected.

  According to this embodiment, since the memory card conversion adapter can always be stored in the battery lid for electronic devices, the inconvenience of carrying the adapter for data transfer to an external device such as a computer separately from the camera can be eliminated.
