置１３となっている。The image pickup device 13 is a box-shaped package 1.
4, a solid-state image pickup device 15 is provided, and the solid-state image pickup device 15 is composed of a quadrilateral plate-shaped CCD device. An R (red), G (blue), and B (green) color filter array is provided on the pixel surface of the solid-state image pickup device 15, and the color image pickup device 13 outputs image signals of three colors. ing.

17) is provided. The LPF 17 removes a high frequency component of the frequency of the subject image light incident through the taking lens 18 and prevents a false color signal output from the imaging device 13.

入射すると、これが色光として検出され、この撮像装置
１３から偽色信号が出力する。That is, since the subject image light contains many frequency components, when the subject image light having a high frequency component corresponding to the pitch of the color filter array enters the image pickup device 13, this is detected as color light. A false color signal is output from this imaging device 13.

る。[0006] Such a false color signal is generated by, for example, when a subject having a striped pattern is photographed, the striped pattern has a color filter.
This tends to occur when the pitch of the array is matched, and causes color bleeding, color turbidity, moire, and the like.

できる。The above-mentioned LPF 17 for preventing false color signals
Is an optical low-pass filter utilizing the birefringence effect of quartz as shown in FIG. In this LPF 17, the separation width d of the ray due to birefringence, that is, the width d between the ordinary ray La and the extraordinary ray Lb is determined by the thickness t of the crystal. Therefore, by determining the width d in accordance with the high frequency and high frequency components of the subject image light, the influence of this high frequency component can be prevented.

要である。Further, in a solid-state image pickup device such as a CCD, pixels are independent in a discreet form, so it is necessary to blur the spatial frequency of the object corresponding to the pixel pitch.

It is often used as the LPF 19 constructed by stacking c. In FIG. 9, 20 is the image plane of the solid-state imaging device 15, and X and Y indicate the pixel arrangement direction.

がだし難くなる。As described above, the false color signal generated from the image pickup device 13 can be prevented by the LPF, but these LPFs are expensive because they are blocks of a quartz plate having a highly accurate flatness. In addition, when fixing the LPF, high precision is required for rotation and inclination with respect to the optical axis, so that the number of fixed parts and the like increases, and the cost increases. Fixing accuracy becomes difficult.

が大きくなる。Since the LPF has a considerable thickness, its built-in space must be provided in the lens barrel 11, and since this LPF is arranged behind the taking lens 18, the optical path length is extended. The total optical length becomes long, and the lens barrel becomes large.
【００１２】さらに、ＬＰＦを撮影レンズ１８の後方に

用のカラ−撮像装置を提案する。In order to achieve the above object, the present invention provides a color image pickup for a video equipment having a solid-state image pickup device having a color filter array corresponding to each pixel in a package. In the device, the package or the solid-state image pickup is performed in the combination direction of the X-direction and the Y-direction of the pixel array of the solid-state image pickup element and within the combination-direction distance corresponding to 1/2 of the pixel pitch intervals X 1 and Y 1. A color image pickup apparatus for video equipment is proposed, which is provided with a vibrating means using a piezoelectric element for vibrating the element as a drive source.

Occurs in the direction in which the X-direction and the Y-direction are combined, and the vibration range is a combination of the distance of 1/2 of the X-direction pixel pitch interval X 1 and the distance of 1/2 of the Y-direction pixel pitch interval Y 1. It becomes the distance. For example, under the condition of X 1 = Y 1 , √2 · (X 1 /
It vibrates in the range of synthetic distance of 2).

情報信号を出力する。Since the subject image light is incident while the solid-state image pickup device vibrates as described above, even if the high frequency component of the image light frequency coincides with the pitch of the color filter-array, the image pickup device produces a false image. No color signal is output. Further, in this color image pickup device, since the solid-state image pickup element vibrates, the number of pixels is apparently increased, and the image information signal having the increased resolution is output.
