Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image pickup apparatus, and more particularly, to a color filter array technology in an image pickup unit suitable for increasing the resolution of an image pickup apparatus for picking up a still image.

[0002]

2. Description of the Related Art An image pickup device using a CCD (Charge Coupled Device) can be roughly classified into a single plate type using a single CCD and a multiple plate type using a plurality of CCDs. As the latter method, there is known a three-plate method in which light is separated into three primary colors by a spectral prism or the like, and light of a single color is photoelectrically converted by a single CCD. On the other hand, in the former method, a single CCD is used.
In order to generate a plurality of types of color signals from the CCD, a CCD having a plurality of types of color filters on the light receiving surface is used. The photoelectric conversion element arranged on the light receiving surface photoelectrically converts the specific color light transmitted through the color filter to output a color signal corresponding to the type of the color filter.

In such a single-plate type image pickup device, a predetermined color video signal is generated from the three primary colors of light, R (red), G (green), and B (blue). Often the same R, G, B as the three primary colors are used.

A conventional example of a color filter array using R, G, B is shown in FIG. This color filter array is known as a Bayer array. An image pickup apparatus using this color filter array is described, for example, in "Fine Image Symposium Papers", The Photographic Society of Japan; October 1995, pp. 69-72.

However, an image pickup apparatus using such a primary color filter has a low light utilization factor, and therefore has a low sensitivity at low illuminance, and in particular, has a low resolution when a primary color object is imaged. There is a problem such as.

[0006]

Therefore, as a means for solving the above problems, a method using a complementary color filter is known. FIG. 8B shows an example of a complementary color filter array, and this filter array is widely used in an image pickup apparatus for picking up a moving image. An image pickup device using this color filter is disclosed in, for example, Japanese Patent Laid-Open No. 280496/1990.
No. pp. 147-64.

However, in this color filter array, as shown in FIG. 8B, the horizontal repeating period is 2 pixels, whereas the vertical pixel repeating period is 4 pixels. However, there is a problem that a false signal (moiré) generated when a high frequency component of the input image is folded back to a low range is increased, the vertical resolution is lowered, and a false color different from an actual color is generated.

An object of the present invention is to solve the above problems and to provide an image pickup apparatus capable of picking up a high resolution still image.

[0009]

In order to achieve the above-mentioned object, an image pickup apparatus according to the present invention has a plurality of types of color filters having different spectral sensitivities arranged on an image pickup surface. A color filter that transmits the color of
Color filters that transmit the colors of
Horizontal column filter, vertically adjacent to the first color transmitting color filter, and vertically adjacent to the third color transmitting filter, and vertically adjacent to the second color transmitting color filter. And a color filter that transmits the fourth color is composed of second horizontal column filters that are alternately arranged, and each of the color filters having the above-described arrangement and the color light that has passed through each of the color filters are photoelectrically converted. And a transfer unit that transfers and outputs a pixel signal corresponding to each pixel. For example, the first color is magenta,
The second color was green, the third color was cyan, and the fourth color was yellow.

In the present invention, a complementary color filter is used, and the repetition cycle of the horizontal and vertical color filters is both 2.
Since it is a pixel, it is possible to realize an imaging device having high sensitivity and high resolution.

Embodiments of the present invention will be described below.

FIG. 1 is a view showing the arrangement of an image pickup section of an image pickup apparatus according to the first embodiment of the present invention. In each of the embodiments of the present invention, a normal interline C
A device called a CD (hereinafter simply referred to as CCD) is applied.

In FIG. 1, reference numeral 1 is a pixel composed of a photoelectric conversion element such as a photodiode and a color filter provided on the photoelectric conversion element. In this image pickup unit (CCD 5), a plurality of pixels are regularly arranged in the horizontal and vertical directions. In FIG. 1, only one representative pixel is labeled with a lead line. The color filter provided in each pixel is M
There are four types, g (magenta), G (green), Cy (cyan), and Ye (yellow), and two pixels in the horizontal direction and two in the vertical direction.
The pixels are repeatedly arranged with a total of 4 pixels as a basic unit. Mg is a color filter that transmits blue and red colored light, and similarly, G is green colored light, Cy is green and blue colored light,
Ye is a color filter that transmits green and red color lights respectively.

Each pixel photoelectrically converts the color light transmitted through the color filter provided for each pixel to generate a pixel signal.
The pixel signal accumulated in each pixel by exposing for a certain period of time is read out to the vertical CCD (vertical transfer unit) 2 provided adjacent to the pixel column. Pixel signals read in the vertical CCD 2 are sequentially transferred in the vertical CCD 2.
The pixel signal transferred from the vertical CCD 2 is transferred to the horizontal CCD (horizontal transfer unit) 3, then transferred in the right direction in the horizontal CCD 3 and output from the output unit 4. By the above operation, the pixel signal generated by each pixel is output.

Here, in this embodiment, one of the color filters is used.
As an example, the filters shown in FIGS. 1 and 2A are used, but as the color filter, Mg and Cy are used as in the second embodiment of the present invention shown in FIG. 2B. As shown in FIG. 2C, the same horizontal row, G and Ye are arranged in the following horizontal row, and Mg and Ye have the same horizontal row, G, as in the third embodiment of the present invention shown in FIG. And Cy may be arranged in the following horizontal row.

In these color filter arrays, Mg, C
Since the complementary color filters of y and Ye are used, the light utilization rate is high and the sensitivity and resolution are high. Further, the repetition cycle of the color filter array is as small as 2 pixels in both the horizontal and vertical directions, and the occurrence of false signals is small, so that high resolution can be obtained.

Next, a fourth embodiment of the present invention will be described. FIG. 3 shows the three primary color signals R (red) and G using the CCD having the color filter array shown in FIG.
(Green) and B (blue) signals, a luminance signal Y, and color difference signals RY and BY are generated, and these generated video signals (still images) can be recorded on a recording medium. ,

Therefore, the R, G, and B signals are, for example, R = Ye + Mg-Cy (4) Formula G = Cy + Ye-Mg (5) Formula B = Cy + Mg-Ye (6) Formula It can be generated by the arithmetic expressions represented by the above equations (4) to (6). The R, G, and B signals obtained by the above equations (4) to (6) may be subjected to known processing such as white balance correction and gamma correction, if necessary.

The luminance signal Y is a complementary color of Mg, Cy,
By using the Ye signal and the G signal obtained by the equation (5), Y = Mg + G + Cy + Ye (7) Equation (7) can be obtained by the above equation (7).

Here, the brightness signal Y is obtained by the equations (4) to (6) instead of the equation (7), and the values of R, G and B are obtained.
It may be obtained from the signal using the following equation (8), which is a relational expression between the R, G, B signals and the luminance signal Y. Y = 0.3R + 0.6G + 0.1B Equation (8) Note that the coefficients applied to the R, G, and B signals in Equation (8) may be appropriately changed according to the reproduction method of the video signal. Further, the color difference signals RY and BY, or the color difference signals U and V obtained by multiplying these color difference signals by a predetermined coefficient,

Generally, these recording media can be removed and replaced, but they may be fixed in the imaging device. Further, a recording medium such as a memory card that can read data in the memory by an external device such as a personal computer may be used.

The processing described above is performed by the signal processing circuit 34, and the control circuit 36 controls the start timing of the image pickup unit, the timing of signal processing, various parameters in signal processing, and the like. Further, part or all of these signal processing may be performed by the control circuit 36. The control circuit 36 is usually composed of a microcomputer and, if necessary, a peripheral circuit such as a RAM or a ROM. Input / output of the video signal data among the signal processing circuit 34, the control circuit 36, and the recording medium 37 is performed via the bus 38. In the control circuit 36, JPEG (Joint
Image compression such as Photographic Experts Group) may be performed by software processing. The generated video signal data can be output from the I / F circuit 39 by connecting to an external device such as a personal computer.

Next, fifth to eighth embodiments of the present invention will be described. In the first to third embodiments described above, the color filter array shown in FIG. 2 is used.
In the fifth to eighth embodiments, (a) to (d) of FIG.
The color filter array shown in is used. The entire structure of the image pickup apparatus is the same as that shown in FIG. 3, and its image pickup unit (CCD)
The only difference is the color filter array in.

In the arrangement according to the fifth embodiment of the present invention shown in FIG. 4A, G is arranged in two diagonal pixels in the basic unit of two pixels in the horizontal direction and two pixels in the vertical direction, and the remaining G pixels are arranged. Two
Cy and Ye are arranged in the pixel. In the case of this color filter array, the G signal is obtained directly from the G pixel, and B is (Cy
-G) and R can be generated by the operation of (Ye-G). The luminance signal Y may be generated by adding each pixel signal.

In the arrangement according to the sixth embodiment of the present invention shown in FIG. 4B, in a basic unit of 2 pixels in the horizontal direction and 2 pixels in the vertical direction, Mg is arranged in two diagonal pixels and the remaining Cy and Ye are arranged in two pixels. In the case of this color filter array, the color difference signal can be directly generated by the calculation of the following expressions (9) and (10). R−Y = 0.6 (Mg−Cy) −0.1 (Mg−Ye) (9) Formula B−Y = −0.3 (Mg−Cy) +0.9 (Mg−Ye) Expression (10) Further, the luminance signal Y may be generated by adding each pixel signal.

In the array according to the seventh embodiment of the present invention shown in FIG. 4C, in the basic unit of 2 pixels in the horizontal direction and 2 pixels in the vertical direction, an all-color transmission filter W (white) is used as two pixels diagonally. And Cy and Ye are arranged in the remaining two pixels. In the case of this color filter array, R is (W-C
y) and B can be respectively calculated by the calculation of (W-Ye). G can be obtained by using the equation (2) or (3) based on the obtained B or R signal and the complementary color Cy or Ye signal. The luminance signal Y may be generated by adding each pixel signal. Since this color filter uses a W filter that transmits all colors, it has high sensitivity.

The color filter arrays (of the fifth to seventh embodiments) shown in FIGS. 4A to 4C are 90
Since it is symmetric with respect to the degree rotation, it is possible to obtain an image of the same image quality (resolution) regardless of whether the image pickup device is horizontal or vertical during photographing.

The arrangement according to the eighth embodiment of the present invention shown in FIG. 4D is an arrangement in which W, G, Cy and Ye filters are arranged in a basic unit of 2 pixels in the horizontal direction and 2 pixels in the vertical direction. In the color filter shown in FIG. 2A, a W filter is used instead of the Mg filter. In the case of this color filter array, the G signal is obtained directly from the G pixel, and the R and B signals are obtained by the following equation (11) and (1).
It can be generated by the calculation of the equation (2). R = W-Cy + Ye-G (11) Formula B = W-Ye + Cy-G (12) Formula Further, the luminance signal Y may be generated by adding each pixel signal. In the row where the filters are arranged, (W
+ G), in the row where Cy and Ye are arranged, (Cy
The luminance signal Y may be generated by + Ye). Also,
It is also possible to delay the signal one row before and add all four types of signals to obtain a luminance signal.

The color filter shown in FIG. 4 (d) has good sensitivity because it uses a W filter that transmits all colors. In addition, in this color filter array, a row in which W and G are alternately arrayed and a Cy
Since the color composition in the two rows of the rows in which the and Ye are alternately arranged is equal to R + 2G + B, the moire of the luminance signal is small, and high resolution in the vertical direction can be achieved.

A ninth embodiment of the present invention will be described.
FIG. 5 is a view showing the arrangement of an image pickup section (CCD) of an image pickup apparatus according to the ninth embodiment of the present invention. The image pickup unit (CCD 50) of the ninth embodiment is also an interline CCD as in the above embodiments.

In the first embodiment shown in FIG. 1, since the number of pixels lined up in the vertical direction is equal to the number of stages of the vertical CCD 2, the signals of all pixels can be output independently. In the CCD 50 of the ninth embodiment, the number of stages of the vertical CCD 2 is half the number of pixels in the vertical direction, and the signals of all pixels cannot be read simultaneously. Therefore, the interlaced reading is performed by dividing the signals of all the pixels twice.
That is, first, in the first read, the pixels in the odd rows are read to the vertical CCD 2 all at once, and the vertical CCD 2 and the horizontal C are read.
Transfer and output CD3. Then in the second read,
Pixels in even rows are read out to the vertical CCD 2 all at once, and the vertical C
CD2 and horizontal CCD3 are transferred and output.

If the reading is performed twice in this way, all pixel signals can be read independently even if the number of stages of the vertical CCD 2 is smaller than the number of pixels in the vertical direction.
In the ninth embodiment, the number of stages of the vertical CCDs 2 is half that in the first embodiment shown in FIG. 1, so that the configuration of the image pickup unit is simple.

A tenth embodiment of the present invention will be described. FIG. 6 shows the R, G and B signals which are the three primary color signals, the luminance signal Y and the color difference signals RY and BY (color difference signals U and V), which are obtained by using the image pickup section shown in FIG. It is a block diagram of an imaging device concerning a 10th embodiment of the present invention constituted so that it can generate and can record on a recording medium.

In FIG. 5, 50 is a CCD whose configuration is shown in FIG. 5, 51 is a memory, 52 is a shutter, and 53 is a shutter drive circuit. In addition, in FIG. 5, elements equivalent to those in FIG. 3 are designated by the same reference numerals as those in FIG.
In the tenth embodiment, as described above, the signal reading from the CCD 50 is performed twice. Therefore, the signal read from the CCD 50 in two steps is first passed through the amplification circuit 32 and the A / D conversion circuit 33, and then the signal processing circuit 34.
Before performing the signal processing in, the data is sequentially written in the memory 51 via the bus 38. A RAM or the like is used as the memory 51. Below, with respect to the signals recorded in the memory 51, FIG.
The same signal processing as in the case of the fourth embodiment shown in FIG.

In the tenth embodiment, the signal reading from the CCD 50 is performed in two steps, but the exposure timing must be the same when the CCD 50 captures an image to be read in two steps. In order to control the exposure timing, the tenth embodiment includes a shutter 52 and a shutter drive circuit 53 for driving the shutter 52. Exposure by the shutter 52,
The signal read timing from the CCD 50 is as shown in FIG. First, at time T1, the shutter 52
To open the exposure, and end the exposure at T2.
The exposure time T is controlled by the control circuit 36 so that the level of the output signal from the CCD 50 becomes an appropriate value. After the exposure is completed, the signal read from the CCD 50 is the first time between T2 and T3, and the second between T3 and T4.
It will be held twice and twice.

In the tenth embodiment, the same effect as that of the fourth embodiment of FIG. 3 is obtained, but the CCD 50 having the simple structure shown in FIG. 5 can be used.
