Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of an improved *imaging device. In particular, the present invention relates to the structure of a solid-state image sensor for an image carrier suitable for obtaining a JI still image and a system using the same.

Conventional solid-state imaging devices such as COD cannot take the next picture unless the charge is transferred to the transfer section, making it unsuitable for taking several pictures in succession in a short period of time.In other words, conventional solid-state imaging devices #i As shown in FIG. 1, one stage 6 of a charge transfer register 2 is associated with each photoelectric conversion region 1, and synchronized from each photoelectric conversion region 1 to an analog shift register 2. It has a structure in which the charges are transferred and these charges are transferred to the analog registers 2 and 4. Therefore, unless all the charges are removed, the next picture cannot be drawn. The lower limit of the cycle for taking one photo was limited by the m-output time.

Motomi @Hiro KIll at the same time as eliminating the drawbacks of the above conventional technology
The purpose of the present invention is to provide a photographing device that can import image information of [&] using any tie-down machine and output it at any timing.

The present invention will be explained in detail below based on the drawings.

1I211 is a diagram showing an example of the configuration of this actual product, No. 31.
1 is a diagram showing an example of the drive timing.

10 is a photoelectric conversion area, 11.12 is a plurality of charge storage 111m related to misfires, 5.15 is a direct fuse shift register, 14 is a horizontal anode register, and 15 is an electrode for charge storage. .

Charges accumulated in each photoelectric conversion region 10 are simultaneously transferred to the first charge book 1111 by a dart pulse φIK as shown in #I3.
11, and then the gate pulse φ2 transfers the charge storage of lI2 to 111S121j1, and then the dirt pulse φ2 transfers the charge to the superimposed afw register 13.
1, is transferred in the stacking direction by the vertical analog shift register 13, and further transferred horizontally by the horizontal analog shift register 14 and output. Let φV be the transfer tarot of the direct analog shift register, and φH be the transfer tarot of the horizontal analog shift register. -3E mediumφ

Corresponds to the i-image accumulation time. S. is the accumulation start time of Imfa in series 1. It goes without saying that 811 Gm'L'j can be arbitrarily set.It goes without saying that it may be any line order other than the work shown in the figure.

With this configuration, it is possible to accumulate multiple times of LII image information in each photoelectric conversion section at arbitrary time intervals.

Therefore, multiple images can be taken regardless of the readout time from the image sensor, and it is possible to perform high-speed continuous shooting. It is used as a color imaging device to obtain ML images with little d-color shift.

The 4th m is a diagram showing the second embodiment of the present invention, in which 21 is a photoelectric conversion area, 22 is a Hiro-straight tw. 1
(Each 1 26 of each is a horizontal anatomical register 7 register. The electric charge transducer pulse produced in each -electrical conversion region 21 moves to a predetermined a priori 25 of the anatomical register 25, and the normal Similar to OOD, it will be destroyed.24.
25 is a new addition in the misfire @ to the one that incorporates the charge storage part of the example of the actual theory in the analog syllable) Regis IIIe. No matter how many stages are added, it is a storm.

FIG. 5 is a diagram showing an example in which the output A of the image sensor is connected to the horizontal shift register.It is good practice to have, for example, three horizontal shift registers, each with the first and second registers. Second. This corresponds to the fifth image signal. The number of horizontal analysis shift registers 52 may be equal to the number of stages of straight analog four-dash registers for each photoelectric conversion region shown in FIG.

Diagram 6 shows the 00D using a frame sequential system catheter imaging system.
41F100DKjtMeans for making a 1mm optical image, 42 is a color filter disk, 43 is a drive source for the color filter disk, 44 is a COD, 45 is a red transmission filter, 46 is a green transmission filter/-147 is actually a color transmission filter. The color of the filter is not limited to these colors and may be a complementary color. Of course, the number of nine cards is not limited to three. The color filter 42 obtains a color image signal by sequentially changing the color filter of the 30D cocoon by a drive source 43.

The 7th m(a) uses the 7-frame system as described above, but in order to change the optical path length from the lens image to the carrier image-transfer image. Means '51゜52
．． It is possible to change the imaging position by arranging 5" 5. For example, as shown in Figure 8, you can use the different 1kh gear of
II! To 1 is equivalent to changing the amount of extension of the lens i. That is, for example, as shown in Figure 9IHm), an object 100 is imaged 1ij by changing the optical path length R105.
K! If Sosui and front bottle, joint bottle.

I'm happy with the brass statue in the shape of the back bottle. This is Ori mryo sogo and nine and etc *-1, +rezotLJIg 1011 (1101,
Corresponds to -11 at position 1'02°105. Changing the position of the captured image means changing the amount of lens extension, so changing the optical path length means changing the amount of lens extension. Since 102 is in focus at @, 101 and 105 correspond to the front bin and Il bin states.

Figure 9 (11 shows the relationship between the amount of sharpness of the m image in the front bin, the rear bin, and the rear bin, and the amount of advance, and S 凰 is the evaluation amount for the front bin image 101, S3 is the evaluation amount for the combined bin l1ii So 102, and is the evaluation amount for the Sakogo bin lj image 106. From this, it is possible to determine whether the meeting is in the focused state 11 and whether it is a straw bin or a straw bin. You can also perform automatic focus adjustment.

Note that the focus determination may be performed using two images using the KaA image, or may be performed using a larger number of images.

That’s 1! By adding a transfer section and a storage section to the solid-state image sensor, as in the case of iJi, it becomes possible to sequentially take multiple images in a short period of time. In addition, since color images can be obtained using the field or frame sequential method, images of different colors can be captured in a short time, which also has the effect of allowing color images to be captured without color blur for moving subjects. . Furthermore, by taking multiple images by changing the path length, m
This also has the effect that the focal field shape can be determined at the same time as an image is photographed, and that even moving m-images can be photographed with high precision.
