DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an example of an electronic camera according to an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 shows the back side of the digital camera. On the front side of the digital camera, although not shown, an imaging lens and an image sensor (CCD or the like) that receives subject light that has passed through the imaging lens are provided.
[0012]
In FIG. 1, a mode setting dial 1 and a shutter button 2 are provided on the right end side of the upper surface of the housing of the digital camera. The mode setting dial 1 is a “still image shooting mode” for recording a still image, a “single recording mode” for creating a new file for each shooting and recording a moving image, and additionally recording a moving image in an already recorded moving image file. It is an operation means for setting a mode such as “continuous recording mode”, and is rotated so that the dial is set to the position of the mode to be set. The shutter button 2 is a means for instructing the start of still image shooting, and is also used as a means for instructing start / stop of moving image shooting (a so-called recording switch). The shutter button 2 is composed of a two-stage switch having a switch that is turned on when half-pressed and a switch that is turned on when fully pressed.
[0013]
On the back surface of the housing of the digital camera, 3 is a viewfinder eyepiece. Reference numerals 4 and 5 denote a shift key and a display key, respectively. Reference numeral 6 denotes a shooting mode / playback mode switching lever. PW is a power switch and is provided at the center of rotation of the switching lever 6, and the power is turned on and off each time the switch is pressed. 7 and 8 are a cancel key and an execution key, respectively. Reference numerals 9 and 9 are multifunction cross keys. Reference numeral 54 denotes a liquid crystal monitor.
[0014]
FIG. 2 shows an outline of the circuit configuration of the digital camera, which will be described below. The light that has passed through the taking lens 10 is incident on a CCD solid-state imaging device (hereinafter referred to as CCD) 14 after the amount of light is adjusted by the diaphragm 12. A CMOS image sensor or other imaging device may be used instead of the CCD 14.
[0015]
On the light receiving surface of the CCD 14, a large number of photosensors are arranged in a plane, and a Bayer array or other predetermined color filter array structure is provided. The optical image of the subject formed on the light receiving surface of the CCD 14 via the photographing lens 10 is converted into signal charges of an amount corresponding to the amount of incident light by each photosensor. The signal charge accumulated in each photosensor is read out to the shift register by a read gate pulse applied from the CCD drive circuit 16, and sequentially read out as a voltage signal corresponding to the signal charge by a register transfer pulse.
[0016]
The CCD 14 has an electronic shutter function that can sweep out the accumulated signal charge by a shutter gate pulse, thereby controlling the charge accumulation time (shutter speed). The CCD 14 has a function of thinning out and reading out signal charges from the photosensor on the light receiving surface. Then, when recording a moving image, the data is thinned out in the vertical direction and read out. When recording a still image (when recording high pixels), the data of all pixels is read out without being thinned out.
[0017]
The voltage signal sequentially read from the CCD 14 is applied to a correlated double sampling circuit (CDS circuit) 18 where the R, G and B signals for each pixel are sampled and held and applied to the A / D converter 20. It is done. The A / D converter 20 converts the R, G, and B signals sequentially added from the CDS circuit 18 into digital signals and outputs them. The CCD drive circuit 16, the CDS circuit 18, and the A / D converter 20 are driven in synchronization by a timing signal applied from the timing generation circuit 22.
[0018]
The R, G, and B signals output from the A / D converter 20 are temporarily stored in the memory 24, and then the R, G, and B signals stored in the memory 24 are added to the digital signal processing circuit 26. The digital signal processing circuit 26 includes a synchronization circuit 28, a white balance adjustment circuit 30, a gamma correction circuit 32, a Y / C signal creation circuit 34, a memory 36, and the like.
[0019]
The synchronization circuit 28 converts the dot-sequential R, G, B signals read from the memory 24 into simultaneous equations and outputs the R, G, B signals to the white balance adjustment circuit 30 simultaneously. The white balance adjustment circuit 30 includes multipliers 30R, 30G, and 30B for increasing and decreasing the digital values of the R, G, and B signals. The R, G, and B signals are respectively multiplied by the multipliers 30R, 30G, and 30G, respectively. Added to 30B. A white balance correction value (gain value) for white balance control from a central processing unit (CPU) (computer) 38 is added to other inputs of the multipliers 30R, 30G, and 30B. , 30B respectively multiply the two inputs, and output the R ′, G ′, B ′ signals adjusted for white balance by this multiplication to the gamma correction circuit 32.
[0020]
The gamma correction circuit 32 changes the input / output characteristics so that the white balance adjusted R ′, G ′, B ′ signals have the desired gamma characteristics, and outputs them to the Y / C signal creation circuit 34. The Y / C signal creation circuit 34 creates a luminance signal Y and chroma signals Cr and Cb from the gamma-corrected R, G, and B signals. The luminance signal Y and chroma signals Cr and Cb (YC signal) are stored in the memory 36 in the same memory space as the memory 24.
[0021]
The YC signal stored in the memory 36 at the time of shooting is added to the compression / decompression circuit 56. The other input of the compression / decompression circuit 56 is added with information indicating the preset image quality (compression ratio of normal, fine, etc.) from the CPU 38. The compression / decompression circuit 56 is set with the YC signal. Compress with image quality compression rate. In the JPEG algorithm, the YC signal is divided into blocks of 8 × 8 pixels, the data of each block is subjected to discrete cosine transform, and then divided by a quantization table prepared for each compression rate. Further, the quantized data is encoded by the Huffman table.
[0022]
The encoded data is recorded on a recording medium, that is, a semiconductor memory card 64 such as smart media or compact flash through the media controller 60 and the card interface 62. Instead of the memory card 64 as a recording medium, a disk-shaped magneto-optical disk such as a CD-R or DVD-R or other recording medium is also possible. The recording medium is not limited to a removable medium, and may be a recording medium (such as an internal memory) built in the camera.
[0023]
The CPU 38 is a control unit that controls each part of the camera, and controls the operation of the entire camera according to a predetermined program. The CPU 38 comprehensively controls each circuit based on operation input signals from the camera operation unit 40 including the mode setting dial 1, the shutter button 2, the cross key 9 and other various operation means shown in FIG. Various controls such as AF) control, automatic exposure (AE) control, auto white balance (AWB), image signal processing control, recording medium read / write control, and display control on the liquid crystal monitor 54 are performed.
[0024]
The autofocus control is, for example, contrast AF that moves the photographing lens 10 so that the high-frequency component of the G signal is maximized, and the drive unit 42 is set so that the high-frequency component of the G signal is maximized when the shutter button 2 is half-pressed. Then, the photographing lens 10 is moved to the in-focus position.
[0025]
The automatic exposure control takes in R, G, and B signals, obtains the subject luminance (shooting EV value) based on the integrated value of these R, G, and B signals, and uses the shooting EV value at the time of shooting. Determine the aperture value and shutter speed. In the still image shooting mode, when the shutter button 2 is fully pressed, the aperture 12 is driven via the aperture drive unit 44 so that the determined aperture value is obtained, and the electronic shutter is used so that the determined shutter speed is achieved. The charge accumulation time is controlled to capture one frame of image data, and after necessary signal processing, it is recorded in the memory card 64.
[0026]
The first exposure is performed with a predetermined exposure value. The average calculation values of the R, G, and B signals for each divided area are calculated by the integrating circuit 48 and then added to the CPU 38. Multipliers 50R, 50G, and 50B are provided between the integration circuit 48 and the CPU 38, and an adjustment gain value for adjusting variation of the devices is added to the multipliers 50R, 50G, and 50B. It has become.
[0027]
Next, an operation when a moving image is recorded by the camera 1 configured as described above will be described. When shooting a moving image, the mode setting dial 1 is set to “single recording mode” or “continuous recording mode”. With this dial operation, the camera is set to a mode capable of recording a moving image (moving image recording mode). In this case, when the shutter button 2 is pushed once, movie shooting starts. For example, image data is taken into the memory 24 at a frame rate of 30 frames per second, and when the shutter button 2 is pushed once again, movie shooting is started. Ends. Even when the shutter button 2 is not pushed once again, when the capacity of the memory 24 is full, the shooting of the moving image automatically ends.
[0028]
When shooting of the moving image is completed, the image data temporarily stored in the memory 24 is subjected to signal processing, compression processing, and the like, and is recorded in a recording medium in a predetermined file format. In this example, recording is performed in the Motion JPEG format, but the file format is not limited to this, and other file formats such as MPEG may be applied.
[0029]
Next, a recording condition setting method during moving image shooting and a method for selecting an existing moving image file used in the continuous recording mode will be described. When the continuous recording mode is set with the mode setting dial 1 and a setup button (not shown) is operated, a setup screen for selecting recording conditions such as image quality, the number of pixels, and a frame rate and a connected image is read from the ROM 58. This setup screen is displayed on the liquid crystal monitor 54 via the mixer 52.
