Like this, camera head 100 has the lens devices that comprises the 1st lens the 110, the 2nd lens 120 and lens barrel 200.The optical axis of the 1st lens of claiming sometimes to exist in central authorities 110 is the center of lens devices.
The example that the piece of the photographing module that Fig. 3 model utility ground expression camera head 100 has constitutes.As the piece formation of the 1st camera system the 101, the 2nd camera system 102a and the 2nd camera system 102b, the mode sectional drawing on the plane of the optical axis that comprises the 1st camera system the 101, the 2nd camera system 102a and the 2nd camera system 102b is shown here.Moreover Fig. 4 is illustrated in the mode sectional drawing on the plane of the optical axis that contains the 1st camera system the 101, the 2nd camera system 102c and the 2nd camera system 102d.
Picture signal generation portion 170 has portion of reading 140 and image production part 150.In the 1st camera system 101, the 1st optical system 115 comprises the 1st lens 110 and the 1st aperture portion 112.The 1st image pickup part 119 comprises the 1st color filter array 116 and the 1st imaging apparatus array 118.In the 2nd camera system 102a, the 2nd optical system 125a comprises the 2nd lens 120a and the 2nd 122a of aperture portion.The 2nd image pickup part 129a comprises the 2nd color filter array 126a and the 2nd imaging apparatus array 128a.
The 2nd camera system 102b, the 2nd camera system 102c and the 2nd camera system 102d all are the 2nd lens 120a, the 2nd 122a of aperture portion, the 2nd color filter array 126a, the same substantially optical parameters of the 2nd imaging apparatus array 128a of the optical parameter that has with the 1st camera system 101a.Therefore, omit explanation.
The 1st lens 110 that the 1st camera system 101 has have the 1st optical characteristics with respect to shooting light.A plurality of the 2nd lens 120 that the 2nd camera system 102 has have the 2nd optical characteristics respectively with respect to shooting light, and have different optical axises mutually.Here, so-called optical characteristics can the illustration optic response, imaging characteristic, light characteristic.As the index of expression optical characteristics, but the illustration depth of focus, focal length, optical transfer function, F value, effective aperture, MTF etc.A plurality of the 2nd lens 120 can have the optical characteristics that equates substantially mutually, on image planes, form the picture that equates substantially for same object point.Such as, a plurality of the 2nd lens 120 on image planes separately, such as the picture of the size that forms the brightness that equates substantially, the shape that equates substantially, equates substantially.Because the optical axis of a plurality of the 2nd lens 120 leaves mutually at interval, so the so-called picture that equates substantially that forms does not mean to form images in the identical position on image planes separately.
So, a plurality of because the 2nd lens 120 can be provided with, so can the resulting separately subject body image through a plurality of the 2nd lens 120 be synthesized, generate 1 subject body image.As an example, overlap the image that is obtained separately through a plurality of the 2nd lens 120.Because the optical axis of a plurality of the 2nd lens 120 is positioned on the concentric circles,, can generate with the centre of gravity place of the optical axis of the 2nd lens 120 the corresponding subject body image of picture when taking as viewpoint so the coincidence through this image is handled.
And the center of gravity of a plurality of the 2nd lens 120 optical axises is positioned at the optical axis position of the 1st lens 110.Therefore, according to the position that the subject body image that obtains is handled in the coincidence of image, will be consistent substantially with the position of the subject body image that obtains through the 1st lens 110.Therefore; Even do not consider the difference of optical axis position of 120 on difference and the 1st lens 110 and the 2nd lens of the optical axis position of 120 on a plurality of the 2nd lens, can very easily synthesize the subject body image of a plurality of the 2nd lens 120 and the subject body image of the 1st lens 110.
About optical characteristics, the F value of establishing the 2nd lens 120 is bigger than the 1st lens 110.For example, it is little to establish effective aperture ratio the 1st lens 110 of a plurality of the 2nd lens 120.At this example, the 1st lens 110 become the lens also brighter than the 2nd lens 120.The 2nd lens 120 monomers become the lens darker than the 1st lens 110.But the 2nd lens 120 exist a plurality of, can synthesize the image that obtains through 120 shootings of the 2nd lens.Therefore, can the one-sided not enough thing of available light quantity in picture forms be prevented trouble before it happens.
Moreover brightness is an example of optical characteristics.The 2nd lens 120 can with the 1st lens 110 brightness, focal length, complex focus from and the depth of focus at least 1 different.
Explanation constitutes about the optics that the 1st camera system 101 has.The 1st lens 110 are imaging lens, will form images at the 1st image pickup part 119 from the G light of subject body.112 pairs of light quantities that see through the 1st optical system 115 of the 1st aperture portion are adjusted.Light through the 1st optical system 115 is restricted to the light through the peristome of the 1st aperture portion 112.
The 1st color filter array 116 contains a plurality of color filters that optionally see through the light of predetermined wave band.The 1st color filter array 116 is according to being formed these a plurality of color filters by predetermined arranged in patterns.For example, the 1st color filter array 116 is rectangular arrangement by these a plurality of color filters and forms.The wave band that each color filter saw through designs according to the shooting purpose and gets final product.All color filters can optionally see through the light of specific band, also can comprise the color filter of a plurality of kinds of the light that optionally sees through different mutually wave bands.
The 1st imaging apparatus array 118 contains a plurality of imaging apparatuss of accepting from the light of subject body through the 1st optical system 115.A plurality of imaging apparatuss that the 1st imaging apparatus array 118 comprises, it is provided with corresponding to a plurality of color filters that the 1st color filter array 116 comprises.Each imaging apparatus receives light to the light that has seen through corresponding color filter in the subject body light that is incident to the 1st color filter array 116.The image pickup signal of the output of each imaging apparatus and the amount respective intensities of the light that receives light.
In the 2nd camera system 102a, the 2nd color filter array 126a comprises a plurality of color filters that optionally see through the light of predetermined wave band.The 2nd color filter array 126a arranges and forms according to the pattern of being confirmed these a plurality of color filters in advance.For example, the 2nd color filter array 126a is rectangular arrangement by these a plurality of color filters and forms.The wave band that each color filter saw through designs according to the shooting purpose and gets final product.All color filters can optionally see through the light of specific band, also can comprise the color filter of a plurality of kinds of the light that optionally sees through different mutually wave bands.
The 2nd imaging apparatus array 128a comprises through a plurality of imaging apparatuss of the 2nd optical system 125a acceptance from the light of subject body.A plurality of imaging apparatuss that the 2nd imaging apparatus array 128a comprises, the corresponding setting of a plurality of color filters that it comprises with the 2nd color filter array 126a.The light that has seen through corresponding color filter among the subject body light among the 2nd color filter array 126a is incided in each imaging apparatus acceptance.The image pickup signal of the light quantity respective intensities of each imaging apparatus output and suffered light.
Describe about the 1st image pickup part 119 and the 2nd image pickup part 129 formations.A plurality of imaging apparatuss that the 1st image pickup part 119 and the 2nd image pickup part 129 have separately are set up at grade.For example, a plurality of imaging apparatuss of having of a plurality of imaging apparatuss that have of the 1st imaging apparatus array 118 and the 2nd imaging apparatus array 128 are formed on the same substrate.For example, a plurality of imaging apparatuss that a plurality of imaging apparatuss that the 1st imaging apparatus array 118 has and the 2nd imaging apparatus array 128 have form with the one side of same technology at same substrate simultaneously.In addition, a plurality of color filters that a plurality of color filters that the 1st color filter array 116 has and the 2nd color filter array 126 have are also to be formed on pairing imaging apparatus top simultaneously with sampling technology.Like this, made 1 light accepting part that one comprises the 1st image pickup part 119 and the 2nd image pickup part 129.The shooting face of the shooting face of the 1st image pickup part 119 and the 2nd image pickup part 129 constitutes the subregion of the shooting face that this light accepting part holds.Moreover the 1st image pickup part 119 and the 2nd image pickup part 129 that the 2nd imaging apparatus array 128 and the 2nd color filter array 126 are arranged that what is called has the 1st imaging apparatus array 118 and the 1st color filter array 116 carry out aggregate erection after can making respectively mutually.
A plurality of imaging apparatuss that the 1st camera system 101 and the 2nd camera system 102 have are by the exposure simultaneously of substantive ground.If each imaging apparatus is made public, then read portion 140 and read image pickup signal from these a plurality of imaging apparatuss.Read the sensing circuit that portion 140 can have a plurality of imaging apparatuss and on same substrate, be formed.This sensing circuit is with respect to the 1st camera system 101 and the 2nd camera system 102 and be provided with 1, and 1 sensing circuit can be read image pickup signal successively from a plurality of imaging apparatuss that the 1st camera system 101 and the 2nd camera system 102 have.Moreover this sensing circuit also can be provided with separately respectively the 1st camera system 101 and the 2nd camera system 102.
A plurality of imaging apparatuss that the 1st camera system 101 and the 2nd camera system 102 have can be MOS type imaging apparatuss.Each imaging apparatus be with same technology when the formed MOS type of the one side of the same substrate imaging apparatus, each of reading optical system that portion 140 can have according to each camera system partly reads.A plurality of imaging apparatuss that a plurality of imaging apparatuss that the 1st image pickup part 119 comprises and the 2nd image pickup part 129 comprise also can be realized with the solid-state imager of CCD type imaging apparatus etc. except MOS type imaging apparatus.
Read the image pickup signal that imaging apparatus that portion 140 has from each camera system reads and be provided for image production part 150.The image production part 150 synthetic image pickup signals of reading from each camera system generate the picture signal of representing 1 image.
An example of the synthetic processing in Fig. 5 presentation video generation portion 150.If image 510 is for through the captured image of the 1st camera system 101.If image 520a, image 520b, image 520c and image 520d are respectively through the 1st camera system 101a, the 1st camera system 101b, the 1st camera system 101c and the captured image that obtains of the 1st camera system 101d.
The picture of enumerating the subject body that the extended line that prolongs with mind-set optical axis direction from lens devices exists is an example, and an example of the synthetic processing of image production part 150 is explained on model utility ground.This subject body is called a last subject body here.And subject body image 512 is that the axle that comprises in the image 510 is gone up the subject body image on the axle.On the axle on subject body image 512a, the axle on subject body image 512b, the axle subject body image 512c and axle to go up a subject body image 512d be respectively the picture that the axle that comprises among image 510a, image 520b, image 520c and the image 520d is gone up the subject body.
The position of the axle in each image being gone up the subject body image describes.The subject body is the subject body that on the optical axis of the 1st lens 110, exists on the axle, so axle is gone up the central authorities that subject body image 512 is positioned at image 510.
When camera head 100 is watched the subject body, the 2nd lens 120a is positioned at the top of the 2nd lens 120b.The 2nd lens 120c is positioned at the right side of the 2nd lens 120d.Under this situation, subject body image 522a is positioned at the below of image 520a central authorities on the axle.Subject body image 522b is positioned at the top of image 520b central authorities on the axle.Simultaneously, subject body image 522c is positioned at the central left side of image 520c on the axle.And subject body image 522d is positioned at the right side from image 520d central authorities on the axle.Because the 2nd lens 120 optical axises are present on the concentric circles, so the position deviation amount that goes up subject body image 522 from the axle at the center of each image 520 equates.Simultaneously, because the optical axis of the 2nd lens 120 is present on the concentric circles, so the directivity of position deviation is an isotropy.
Coincidence is as in 532, overlapping the picture overlapping region 550 that exists as 532 center as subject body image 522a～d overlapping areas on 4 axles.Simultaneously, in overlapping,, exist as picture overlapping region 560 with the zone after the subject body image overlaps on 3 axles among subject body image 522a～d on the axle as the zone on every side that is adjacent to picture overlapping region 550 as 532.Can reproduce an image-region that last subject body image should occupy substantially as overlapping region 550 with as overlapping region 560.
Coincidence is as in 532, except picture overlapping region 550 and the picture overlapping region 560, also comprises on 2 axles of last a subject body image 522a～d the inside the subject body image by the zone of mutual coincidence.Adding the one's respective area as overlapping region 550 and as 560 zones, overlapping region, the image-region that the subject body image should occupy on the axle is reproduced.
In addition, in overlapping as 532, what comprise other only has a zone of the information separately of last subject body image 522a～d.The one's respective area is the most peripheral zone that overlaps as 532.The area of one's respective area strengthens with the position deviation amount and becomes big.Therefore, overlap more greatly then widely more, just become to following the picture of fuzzy region state as 532 position deviation amount., the blur direction of this fuzzy region is isotropic relatively, does not have directivity.Because this cause if compare with fuzzy directive situation, we can say that coincidence does not have distortion as 532, be the very little image of inharmonious sense that looks.In addition, compare with the picture overlapping region 550 of central authorities, the image information of this fuzzy region has only 1/4 intensity.For this cause, feel that visually fog-level is smaller.
In addition, configuration the 2nd camera system 102 of more number more around the 1st camera system 101 becomes high more as the intensity of overlapping region 550.For this cause, the image information of fuzzy region also becomes relatively little.Simultaneously, fuzzy directivity also further is eliminated.
Among this figure,, adopted axle to go up subject body image 522 with being easily understood, Flame Image Process has been described model utility with big parallax deviation to be illustrated as purpose.In fact, under the situation that lets the optical axis of lens separate terrifically in order to obtain bigger parallax deviation, it is big that position deviation can not become.If position deviation is little, fuzzy region diminishes, and overlaps picture and also becomes distincter.
As described above, synthetic coincidence pattern picture that obtains through the coincidence of a plurality of the 2nd lens 120a～a plurality of images that d shooting obtains of image production part 150 and the image that obtains through the 1st camera system 101.Therefore, according to camera head 100, can synthesize a plurality of images that obtain through each camera system shooting with simple Flame Image Process.Such as, can not contain corresponding point matching etc. and handle ground in interior position alignment, synthetic fast a plurality of images, and the outside provided.
Moreover image production part 150 can be applied to as 532 coincidence and be used to reduce fuzzy Flame Image Process.For example, image production part 150 can be to overlapping emphasical processing the in edge that picture is applied to predetermined intensity.Because overlap the fuzzy more closely then big more of picture, so image production part 150 can in subject body distance closely improve the intensity that reduces Fuzzy Processing more with the subject body.Such as, image production part 150 can in subject body distance closely improve the intensity of stressing with respect to the edge that overlaps picture more.Subject body distance can be specified with image pickup mode especially.For example, image production part 150, when the photograph mode of camera head 100 was configured to landscape configuration, it was remote can specifying subject body distance especially.When if photograph mode is set Portrait, can specify subject body distance especially is closely.When if photograph mode is configured to grand pattern, can specify subject body distance especially is point blank.If in the time of the ranging information that records by distance-measuring equipment being utilized, can come the special subject body distance of specifying according to this ranging information.Image production part 150 has been stored the Flame Image Process parameter of the fuzzy reduction processing usefulness of stressing to handle etc. with the corresponding edge of distance in advance; Use and the Flame Image Process parameter that is appropriate to the specially appointed subject body distance of institute, look like to be applied to Flame Image Process overlapping apart from corresponding stored.
