Abstract

SOLUTION: The electric charge of a photodiode 1 is independently transferred to a vertical transfer part 2 every pixels equivalent to two rows, and the electric charge equivalent to a single row is transferred from the part 2 to a horizontal transfer part 3 in the discontinuous horizontal synchronizing periods. Then the electric charge stored in the part 3 is transferred to a signal charge detecting part 4 by an amount equivalent to a single pixel, and the electric charge equivalent to a single row are mixed toward the part 3 from the part 2 in the same horizontal period and the electric charge equivalent to two rows are mixed at the part 3. Moreover, the electric charge is transferred from the part 2 to the part 3 in a horizontal synchronizing period which is different from the discontinuous period and the electric charge equivalent to two rows are mixed at the part 3. Thus, two types of color difference signals can be outputted and three primary colors can be displayed on a single screen.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for driving a solid-state image sensor and a digital still camera using the method.

[0002]

2. Description of the Related Art A digital still camera using a solid-state imaging device is required to have high image quality and high functionality, and the number of pixels is increasing. For example, in the case of a solid-state imaging device having 1.3 million pixels, the number of vertical pixels is about 960, and the number of horizontal pixels is about 128.
0 pixels, about 4 times that of a normal NTSC solid-state imaging device.
It has twice the number of pixels. Also, the frame rate is 1 /
15 seconds, 1 which is the rate in normal television
If the signal is read out as it is, the image cannot be output normally on the display device (such as a liquid crystal monitor) because the motion of the image becomes jerky and jerky. Recent digital still cameras often employ a liquid crystal television or the like as a monitor, and in order to reliably monitor imaging, a signal from such a solid-state imaging device is output to a display device having the same specifications as a conventional television. ,
It is necessary to reduce the number of vertical pixels by some method and read the data at high speed.

FIG. 1 shows a gate configuration diagram of a general solid-state imaging device. In FIG. 1, reference numeral 1 denotes a photodiode, 2 denotes a vertical transfer unit including six-phase gates V1 to V6, 3 denotes a horizontal transfer unit including two-phase gates H1 and H2, and 4 denotes a charge detection unit. In FIG. 1, the photodiode 1 and the vertical transfer unit 2 are arranged in a simplified manner. In an actual solid-state imaging device, the combination of the photodiode 1 and the vertical transfer unit 2 is arranged by the number of horizontal pixels. . In the conventional reading method of this solid-state imaging device, a high voltage (about 15 V) is applied to V1, V3, V5, and V6 of the vertical transfer unit 2.
Is read out from the photodiode 1 to the vertical transfer unit 2, and a vertical transfer unit drive pulse (V 1 to V 6) is input to the vertical transfer unit 2, whereby the charge is reduced to 1
One row is simultaneously transferred to the horizontal transfer unit 3 once during the horizontal scanning period, and the charges transferred to the horizontal transfer unit 3 are applied with a clock of about 24.5 MHz to the horizontal transfer unit 3 to output a signal from the charge detection unit 4. Output.

FIG. 2 is a block diagram of a general digital still camera. In FIG. 2, reference numeral 5 denotes a solid-state imaging device, and 6 denotes a T for controlling driving timing for the solid-state imaging device.
G (Timing Generator), 7 is a V driver that converts the drive timing into a voltage for the solid-state imaging device 5, and 8 is a CDS.
9 is a CPU unit for performing signal processing and memory control, 10 is an LCD for confirming captured data and outputting and displaying as a viewfinder, and 11 is a memory unit. Are respectively shown.

FIGS. 3 and 4 show conventional thinning-out read drive timing charts. FIG. 3 is a timing chart of the first field, and FIG. 4 is a timing chart of the second field. HD and VD are horizontal and vertical synchronization signal pulses, respectively, and are applied to the TG 6 from outside. The CCD output indicates an output from the solid-state imaging device 5.
V1 to V6, H1 and H2 indicate gate input pulses of V1 to V6 of the vertical transfer unit 2 and gate inputs of the horizontal transfer units H1 and H2, respectively.

Conventionally, a solid-state image pickup device 5 is connected to a TG 6 from FIG.
And the read-out drive waveform shown in FIG. 4 is input, pixels are read out every two rows, and the read-out pixels for the two rows are replaced with the horizontal CC.
D, add and output, pass through the pre-processing IC 8 and the CPU 9
The output is displayed on the LCD 10. As a result, it is possible to prevent the image display interval from being lengthened due to an increase in transfer / processing time caused by an increase in the number of pixels.

FIG. 5 shows two types of color filter arrays used this time. Each of the four colors of yellow (Ye), magenta (Mg), cyan (Cy), and green (G)
It is configured based on columns × 4 rows. These color filters correspond to the photodiodes 1: 1 as shown in FIG.

[0008]

However, in the conventional driving method as described above, for example, when charge is mixed by taking the color filter on the right side of FIG. 5 as an example, (Cy + G)-(Y
Only one of the color difference signals, e + Mg) or (Cy + Mg)-(Ye + G), is output to one screen. When the primary color components red, green, and blue are R, G, and B, respectively, Cy =
Since B + G, Ye = R + G, and Mg = R + B, (Cy + G)-(Ye + Mg) = (B + G + G)-
(R + G + R + B) = (G−2R) or (Cy
+ Mg)-(Ye + G) = (B + G + R + B)-(R +
G + G) = (2BG) Only one of them can be output to the screen, so color separation cannot be performed on one screen (only one color difference signal reproduces the three primary colors of R, G, and B) Can not.). Generally, as shown in FIGS. 3 and 4, the color difference signal output from the CCD is only (RY), and the color signal cannot be reproduced. Therefore,
In order to perform color separation to reproduce the three primary colors, it is necessary to develop primary color components for each pixel, and there is a problem that a large amount of resources such as a CPU and a memory are required.

According to the present invention, even a solid-state image pickup device having a color filter performs thinning and charge mixing and can output two kinds of color difference signals on one screen, thereby requiring complicated processing and hardware resources. It is intended to be able to output directly to a display device without any change.

y + Mg) is output to the screen as a color difference signal. When the horizontal scanning line number is an odd number, the third line in FIG. 5 is shifted by one pixel, so that the third line of the color filter array on the left side of FIG. Because it is.

Here, the primary color components red, green and blue are represented by R, G, B
Where Cy = B + G, Ye = R + G, Mg = R +
6 and FIG. 7, when the horizontal scanning line number is an even number, (Ye + Mg)-(Cy + G)
= (R + G + R + B)-(B + G + G) = (2R + G +
B)-(B + 2G) = (2R-G), and a color difference signal can be obtained. On the other hand, when the horizontal scanning line number is odd, 1
(Ye + G)-(Cy +
Mg) = (R + G + G) − (B + G + R + B) = (R +
2G) − (2B + G + R) = (G−2B), so that two types of color difference signals can be obtained every other row.

Here, 1280 (H) × 960 (V)
In the solid-state imaging device having the color filters of the first embodiment, the data is thinned out by 垂直 in the vertical direction, and two rows are mixed by the horizontal transfer unit.
The case of outputting as rows, that is, the case of thinning out to 1/4 has been described, but the number of pixels, the thinning amount, and the mixing amount are not limited to the present embodiment in the present invention. Further, when the horizontal scanning line number is an odd number, the application of the H1 and H2 pulses when the horizontal scanning line number is an even number is not limited to the above, and the same applies to the opposite case. The present invention also does not particularly limit the method of combining the output color difference signals G) and (G-2B).
