Abstract

A camera system includes a camera main body and a camera head mounted to the camera main body. A main body CPU of the camera main body determines whether or not an image signal transmitted from the mounted camera head can be processed by a signal conversion processing section of the camera main body based on ID information and signal conversion processing information downloaded from the camera head upon mounting the camera head. When it is determined that the signal cannot be processed by the signal conversion processing section by the main body CPU, the camera main body sets a RAW data recording mode for recording RAW data on a recording medium by adding a part of the signal conversion processing information of the camera head as data without performing signal processing in the signal conversion processing section.

On the top of Fig. 3 is id information, is signal conversion processes information below id information.Such as, id information shown in Figure 3 is the ID number that is used to discern camera head, this ID number is downloaded and is installed in the camera body that has camera head, so that be identified in the type of the camera head of installing on the camera body at the main body CPU100b on the camera body (referring to Fig. 2).Signal conversion processes information shown in Figure 3 is held by camera head 1a.Yet according to present embodiment, camera body 1b also has signal conversion processes information shown in Figure 3.If signal conversion processes information just is equivalent to this id information when from camera head 1a download id information, this signal conversion processes information is set in Digital Signal Processing part 103b so.More specifically say, if id information on camera body, so just need not be again from camera head 1a download signal conversion process information.
Yet, consider the memory span in the camera body, store whole id informations and signal conversion processes information is inefficent.Therefore, can from camera head, download as shown in Figure 3 signal conversion processes information.
About signal conversion processes information, be pointed out that according to descending: the CFA of CCD12a arranges, the dark and CCD temporary storage location in position of pixel count, the pixel coordinate of pointing out effective take-off location and the quantity of CCD12a (three kinds of situations, promptly still image, full figure resemble the situation with moving image), the coordinate of pointing out optical black (being referred to as OB below) position as black level's standard, composition order, A/D.
In the signal conversion processes information as shown in Figure 3, (W H) points out pixel count as the combination of Vertical number of pixels W and Horizontal number of pixels H.As shown in Figure 4, (W H) has represented Horizontal number of pixels and Vertical number of pixels.Reference character W 1Be illustrated in the maximum pixel number on the imaging area Width, and H 1Be illustrated in the maximum pixel number on the imaging area short transverse.More specifically say (W 1, H 1) as a bars conversion process information, it has pointed out to produce still image by whole pixels of using CCD 12a.As a bars conversion process information, pointed out to use less than still image signal pixels number (W 1, H 1) pixel count (W 2, H 2) produce the full figure picture signals, same, use less than still image signal pixels number (W 1, H 1) pixel count (W 3, H 3) the generation moving picture signal.So that (X, Y) effective take-off location of expression full figure picture signals and moving picture signal is by combination (W 4, H 4) be illustrated in the pixel count in this image pickup district (shown in the chain-dotted line among Fig. 4 zone).
And CCD12a has the zone that is called as optical black (being referred to as OB below) in its imaging area, is used for Digital Signal Processing part 103b in camera body 1b to inform black level with CCD12b picked-up image the time.The beginning coordinate (XOB) in OB district and length (WOB) also all are represented as a bars conversion process information.
As for dark data by how many bits constitute a pixel in the A/D position, this also is used as a bars conversion process information and points out.The bit number of each pixel can be 8～14bit, and this is referred to do a bars conversion process information.And the CCD temporary storage location is represented the coordinate position of defect pixel, and (X Y) also is used as a bars conversion process information.Fig. 4 is illustrated in 3 position (Xt 1, Yt 1), (Xt 2, Yt 2) and (Xtn, Ytn) defective pixels.Under the situation of defectiveness pixel, the several pixels adjacent with defect pixel are recovered by insertion process.
If be provided with such signal conversion processes information among the Digital Signal Processing part 103b of camera body 1b, just the processing that picture intelligence enforcement and the CCD in camera head via the high-speed serial bus transmission are adapted so.
The structure of camera head 1a as mentioned above.
Get back to Fig. 2, will describe the structure of camera body 1b below.
The operation of camera body 1b is generally controlled by main body CPU100b.System storage 101b by stored routine offers this camera body 1b with the nonvolatile memory 102b that can rewrite storage id information and signal conversion processes information, id information herein and signal conversion processes information is from camera head 1a, and is non-volatile.System storage 101b store to describe the operation sequence of the main procedure of this camera arrangement, comprise with the head CPU19a of camera head 1a handle the full figure picture signals operation sequence, handle the operation sequence of still image signal and handle the operation sequence of mobile picture intelligence.
According to program stored in system storage 101b, receive picture intelligence by the instruction communication of three wire serial bus with by high-speed serial bus, all be subjected to the control of main body CPU100b.Three wire serial bus are driven by three-way serial driver 151b, and high-speed serial bus is driven by high speed serialization driver 150b, and wherein the operation of each driver all is subjected to the control of main body CPU100b.
As previously mentioned, universal serial bus is driven by three-way serial driver 151a on the camera head and the three-way serial driver 151b on the camera body, so that communication is carried out in instruction.If expression requires to send id information or the signal conversion processes information instruction has been sent to camera head 1a via three wire serial bus from camera body 1b, head CPU19a just reads out in the id information and the signal conversion processes information of storing among the nonvolatile memory 191a of camera head 1a so, wherein id information and signal conversion processes information are provided for three-way serial driver 151a, and are sent among the camera body 1b by three wire serial bus.In such a way, if id information and signal conversion processes information are sent among the camera body 1b, so under the control of main body CPU100b, three-way serial driver 151b just receives id information and signal conversion processes information, and wherein id information and signal conversion processes information are stored among the nonvolatile memory 102b.Nonvolatile memory 102b has by the many abilities to id information and signal conversion processes information of a plurality of camera head storages.When the camera head with the different id information of the id information stored in the nonvolatile memory of camera body 1b with the past was loaded onto, this id information and signal conversion processes information just were downloaded and store.
Load onto camera head 1a, perhaps during power-on switch 14b, just can require to use this three wire serial bus to send id information and signal conversion processes information.If above-mentioned any incident just divides 140b and DC/DC converter that electric energy is supplied to each part that comprises main body CPU100b via the power control part from the long-term power supply of battery Bt.At this moment, also electric energy is supplied in each part of the DC/DC converter of camera head and camera head via mounted contacts.Then, main body CPU100b controls three-way serial driver 151b, sends id information to require camera head 1a by the universal serial bus that three-way serial driver 151b drives.If the id information that receives does not match with the id information of storing in nonvolatile memory 102b, camera head 1a just requires to send signal conversion processes information, and id information that receives and signal conversion processes information are stored among the nonvolatile memory 102b.
In such a manner, when installing camera head 1a, perhaps during energized switch 14b, id information and the corresponding signal conversion processes information of id information (if any) therewith just are stored among the nonvolatile memory 102b under the control of main body CPU.And if set this signal conversion processes information in signal conversion processes part 103b, this camera arrangement 1 just enters stand-by state so, obtains to prepare image.
Yet, such as, if the CFA from the signal conversion processes information that the camera head that is mounted is sent etc. is the image pickup device with emerald green filter, may occur just in the signal conversion processes part, can not carry out the situation of signal processing so.If this situation occurs, so just can not carry out image and obtain, this is very inconvenient.Therefore, can main body CPU100b determine and carry out signal processing by digital signal conversion processing section 103b.As the result who determines by main body CPU100b, if signal conversion processes information according to camera head 1a, and determine and can carry out signal processing by digital signal conversion processing section 103b, signal conversion processes part 103b does not just carry out signal processing so, or any other signal processing beyond the repair-deficiency pixel, and can be in storage card as recording medium with so-called RAW storage.
In such a manner, based on the ID number of downloading from the camera head 1a that is installed on the camera body 1b, the type of main body CPU100b identification camera head 1a.And, main body CPU100b determines whether camera body has the ability of carrying out signal conversion process, this signal conversion process be based on the corresponding signal conversion processes information of ID number, will be converted to the picture intelligence of forming by luminance signal and color difference signal from the picture intelligence that camera head receives.That is to say that this main body CPU both had been equivalent to the type identification part used in the present invention, also was equivalent to the ability determining section.
In such a manner, after having downloaded id information and signal conversion processes information, when carrying out image when obtaining, the instruction that expression requires to send the full figure picture signals just is sent to the camera head 1a from camera body 1b by three wire serial bus.Head CPU19a on camera head 1a receives the requirement of sending the full figure elephant, by the high-speed serial bus that is driven by high speed serialization driver 150a this full figure picture signals is sent among the camera body 1b then.The full figure picture signals that is sent to camera body 1b by high-speed serial bus is fed into digital signal conversion processing section 103b, and digital signal conversion processing section 103b handles in predefined mode thus, is stored in then among the frame memory 104b.The YC signal that is stored in frame memory 104b is fed into LCD control section 105b, by LCD control section 105b full figure is resembled whereby to be presented on the LCD 1050b plate.
When seeing this full figure, operating personnel resemble, when pressing release-push 13b simultaneously, interrupt signal is sent to main body CPU100b and head CPU19a simultaneously, so that interrupt the processing of full figure elephant, and is brought into operation by external interrupt and to be stored in still image handling procedure in the system storage.As shown in Figure 2, when pressing release-push 13b, release signal directly is imported in the external interrupt input pin of main body CPU100b and head CPU 19a.When release-push 13b is pressed, be sent to the CCD12a from TG18a by interrupting the timer time commencing signal that will expose, the head CPU19a on the camera head 1a just makes CCD12a begin to expose.After this, the exposure termination signal is sent to CCD12a from TG18a, and CCD12a will comprise that the still image signal of whole pixel datas outputs among the analog part 13a then.Be output to the still image signal of analog signal conversion processing section 13a, supplied to the A/D part 14a from the analog signal conversion processing section, and be fed among the digital signal conversion processing section 103b by high speed serialization driver 150a.And under the control of main body CPU, the still image signal in signal conversion processes part 103b is compressed to the jpeg file of jpeg format, and is stored among the storage card 108b that is contained among the memory card slot 107b via I/F card 106b.When pattern rotating disk 14b is positioned at the dynamic image pattern, realize interrupting by handling release-push 13b, so that the moving image treatment program that brings into operation.Then, at each preset time, mobile picture intelligence is fed among the digital signal conversion processing section 103b by high-speed serial bus, compresses in the mode of motion JPEG or MPEG compression, and is stored among the storage card 108b.In the present invention, main body CPU and the I/F card picture record part that is equivalent to use.
The invention provides the timer 110b and the time-of-day clock part 111b that are used for Timing Processing, they and the present invention do not contact directly.Such as, if supply with calendar data partly for LCD control section 105b from time-of-day clock, clock and calendar just are presented on the LCD 1050b plate with object so.And camera body 1b has a USB connector 130b.If PC in USB connector 130b connection thus, USB is just driven by usb driver 131b so, and picture intelligence is sent in the PC.Equally, by launch the flash light emission device that the flash of light part 121b of flash of light and the control section 120b that glistens constitute by flash light emission window 12b shown in Figure 1, and the switch on the camera body back side/LED 132b, they are operated via I/O 133b under the control of main body CPU100b.
At this, the power control part that uses description to camera body 1b below divides 140b structure on every side, and the power control part of this structure on camera head 1a divides 100a and DC/DC converter 101a supply of electrical energy.
In this camera arrangement 1, when instructing by three wire serial bus transmission, when requirement is sent id information and signal conversion processes information to camera head 1a, type identification main body CPU100b partly as camera head requires to send id information by camera head when camera head 1a or energized switch 14b are installed, if the id information that wherein receives does not match with the id information that stores in mainframe memory, camera head just is required to send signal conversion processes information so, and id information that receives and signal conversion processes information just are stored in the mainframe memory as previously mentioned.
For realizing said process, require main body CPU100b to detect the reason of power-on.Latch part 160b is used for informing to main body CPU100b the reason of power supply, and divides 140b to write the content of latch part 160b again by power control part.By main body CPU100b via the content among the I/O part 161b sensing latch device part 160b, to inform the reason of power supply to main body CPU100b.If latch part 160b is " H ", the content of I/O part 161b is rewritten as " H ", so just judges camera head and has been mounted, just main body CPU100b sends the requirement of transmitting id information to camera head thus.Equally,, so just be judged as mains switch 14b and be switched on, just thus to each part supply of electrical energy of camera body if latch part 160b is " L ".
In such a manner, just having informed the reason of powering to camera body by I/O, is that still owing to operated mains switch, these are all discerned by camera body because camera head 1a has been installed.If latch partly is " H ", after obtaining id information and signal conversion processes information from camera head 1a, main body CPU100b writes the content of I/O again so, whereby the instruction that divides 140b to send to stop power supply to power control part.
With reference to Fig. 5, below detailed description is provided with the operation of the digital signal conversion processing section 103b of signal conversion processes information.
Fig. 5 is the flow chart of the signal conversion process of digital signal conversion processing section 103b.
This digital signal conversion processing section 103b is made up of the DSP that is called as dynamically programmable (digital signal processor).If among this digital signal conversion processing section 103b, set signal conversion processes information, just operate according to this signal conversion processes information so from the external world.At this, if signal conversion processes information shown in Figure 3 conforms to the ability of the digital signal conversion processing section 103b that is made up of DSP, signal conversion processes information is stored among the digital signal conversion processing section 103b so.If full figure picture signals, still image signal and mobile picture intelligence are sent to the digital signal conversion processing section 103b that is provided with signal conversion processes information from camera head 1a by high-speed serial bus, so just, according to this signal conversion processes information, full figure picture signals, still image signal or mobile picture intelligence are carried out signal processing.
Illustrated among Fig. 5 and when pushing release-push 13b, on storage card 108b, noted the process of still image signal.When on LCD 1050b plate, demonstrating full figure and resemble, proofread and correct full figure picture signals afterwards through γ and just be fed among the frame memory 104b, and on the LCD plate, resemble the image that demonstrates based on the full figure picture signals of storing among the frame memory 104b with full figure at each preset time.And when noting mobile picture intelligence on the storage card, this pictorial data is compressed according to motion JPEG or mpeg standard, rather than the JPEG compression, is recorded in the storage card then.
With reference to Fig. 5, will be described in the signal processing of the still image signal that carries out among the digital signal conversion processing section 103b below.
As shown in Figure 5, at first, in step S501, carry out the defect pixel correction process.In step S502, carry out the OB offset correction.In step S501, defect pixel (keeping in) is carried out timing, as shown in Figure 4, use the pixel around defect pixel that defect pixel is implemented insertion process.And, when in step S502, carrying out OB deviation process, as reference level (black level), make the picture intelligence relative reference level of outside, OB district shown in Figure 4 carry out the clamp process with the picture intelligence in the OB district.This clamp process is equivalent to OB deviation process.After having carried out offset correction, in step S503, just carry out the black level of whiteness level with respect to this moment regulated, promptly white balance (WB) is regulated.Produce white by the R, the G that add and the mixture of B look, it is equal wherein to have only gain with R, G and each signal of B all to be adjusted to, and just can obtain highly purified white.At this,, according to the colour temperature of the detected light source kind of AWB transducer 11b, regulate each gain of R, G and B look, to produce highly purified white in order to obtain highly purified white.In such a manner, after in R, G and the B look each is carried out gain-adjusted and white balance adjusting, in step S504, will carry out the linear matrix process, be about to the process that rgb signal is converted to the YCC signal of being made up of luminance signal and color difference signal.At this, multiply by rgb signal with 3 * 3 look transition matrixes, and be converted to Y, Cr and Cb signal.Such as, if increase contrast, just carry out conversion to the YC signal by the weight that increases diagonal element in 3 * 3 look transition matrix coefficients so, generation has the YC signal of being made up of luminance signal and color difference signal of high contrast whereby.In step S505, Y-signal is carried out γ proofread and correct.Then, in step S506, Y-signal and C signal carry out synchronously.Then, for luminance signal (Y), in step S5072, carry out the process of contour accentuation, and in step S5071, carrier chrominance signal (C) is carried out the color difference matrix process simultaneously.If two processes are all finished, so just carry out the operation of next step S508, the picture intelligence of being made up of Y-signal and color difference signal Cr (R-Y) and Cb (B-Y) this moment is carried out JPEG and compresses.In step S509, the picture intelligence that compresses is recorded in the storage card of recording medium as image file then.
In such a manner, in digital signal conversion processing section 103b, set the signal conversion processes information of downloading from camera head 1a, and according to the content of setting, 103b handles to picture intelligence by the digital signal conversion processing section.

As previously mentioned, if when installing camera head 1a or energized, by power control part divide 140b from battery Bt to each part power supply that comprises main body CPU100b, just main body CPU100b begins operation so.
Divide step S801 and S802 in the implementing procedure by power control part, wherein when installing camera head 1a, in step S801, by connecting battery Bt and DC/DC converter, power control part divides 140b to power to each part via the DC/DC converter from battery Bt, and in step S802, further power to camera head 1a.Then, main body CPU100b just begins operation.In step S803, main body CPU100b sends out requirement from three-way serial communication to camera head 1a that send signal conversion processes information by.In step S804, main body CPU waits for received signal.If in step S804, downloaded the information of camera head 1a, just so three-way serial driver is received the information of camera head whereby from waiting for that accepting state changes accepting state into by three-way serial driver.And if three-way serial driver has received information, so in step S805, just the information that receives is stored among the nonvolatile memory 102b.In step S806, supspend to camera head 1a and power.Then, in step S807, cut off the power supply of camera arrangement.The operation of this flow process leaves it at that.
In such a manner, when on camera body 1b camera head 1a being installed, id information and signal conversion processes information are just downloaded from camera head 1a.Owing to be not always to carry out image to obtain after having downloaded id information and signal conversion processes information, so power supply is cut off.After this, when carrying out image when obtaining,, after energized, just can carry out image immediately whereby and obtain by the mains switch energized.
(b) part of Figure 14 (a) part and Figure 14 is when camera body 1b goes up camera head 1a to be installed, when power supply is switched on and demonstrates full figure and resembles on display screen, and the flow chart that picture intelligence flows.If the main body CPU100b that uses as the ability determining section determines that digital signal conversion processing section 103b has the ability of carrying out signal conversion processes according to the signal conversion processes information of the camera head 1a that installs in the present invention, so just, implement signal conversion processes according to (a) flow process (identical) partly of Figure 14 with Figure 12, otherwise, implement flow processing based on (b) part of Figure 14.In Figure 14 (b) part, main body CPU100b does not implement all processes of Digital Signal Processing part 103b, and has illustrated on the display screen of LCD1050b, based on the operation sequence of displayed image by the picture intelligence (RAW data) of CCD generation.
As mentioned above, graphic element number or filter array CFA according to the image pickup device that provides for camera head 1a, Digital Signal Processing part 103b can not implement signal conversion processes, wherein shown in the arrow among Figure 14, do not carry out processing based on Figure 14 (a) part flow process, but carry out processing based on Figure 14 (b) part flow process, on display screen, demonstrate black-and-white image whereby based on the RAW data.
In such a manner, by avoiding not showing the state of full figure elephant, on display screen, always demonstrate full figure and resemble.
As previously mentioned, even the signal processing on the camera body does not have the ability of the picture intelligence of sending being carried out signal conversion processes from the camera head of installing, full figure resembles also and can show, and uses the display screen on camera body to replace the camera arrangement of view finder just can realize whereby.
(a) part of Figure 15 and (b) part of Figure 15 are to the flow chart of the correction of (b) part of Figure 14 (a) part and Figure 14.
Though in Figure 14 (a) part and Figure 14 (b) part, directly be presented on the display screen based on the image of the picture intelligence (RAW data) of CCD generation, but the pixel count of the graphic element number of image pickup device and display screen can be unmatched.In the case, if intactly be presented on the display screen, just should may show to such an extent that be not very good by image so based on the image of the picture intelligence of RAW data.
Therefore, if the main body CPU100b as the ability determining section determines that the camera head 1a that installs is the type that a kind of Digital Signal Processing part 103b can not implement signal conversion processes, and the vertical and horizontal figure unit number of the CCD of camera head 1a (referring to Fig. 3) do not match with the vertical and Horizontal number of pixels of the display screen of LCD1050b (pixel count that CPU obtains the LCD that equipped in advance), Digital Signal Processing part 103b just can not implement signal conversion processes so, but may be implemented in the pixel count adjustment process among the step S7075, to regulate the graphic element number by mixing adjacent graphic element.And in step S708, demonstrate image based on the picture intelligence after the pixel count adjustment process by LCD control section as image display portion.In such a manner, according to the size of the display screen of LCD1050b, image is shown.At this, because CCD graphic element number is generally more than the pixel count of display screen, thus reduce the graphic element number by the mixed graph unit, and on the display screen of LCD1050b, demonstrate image.
(a) part of Figure 16 and (b) part of Figure 16 are (a) part of Figure 15 and (b) correction flow chart partly of Figure 15.
If the main body CPU100b as the ability determining section determines that the camera head 1a that installs is the type that a kind of Digital Signal Processing part 103b can not implement signal conversion processes, and the aspect ratio in the image pickup district of CCD12a is different from the aspect ratio of the viewing area of LCD display, Digital Signal Processing part 103b just implements the pixel count matching process so, so that the Horizontal number of pixels of the display screen of the horizontal figure unit number of the picture intelligence that is obtained by CCD12a and LCD1050b is complementary, and the LCD control section 105b by as image display portion demonstrates the image based on the picture intelligence after the pixel count matching process on the display screen of LCD1050b.Then, just at this moment, in step S7076, Digital Signal Processing part 103b makes the slenderness ratio normalization, promptly implements the pixel count matching process.If the not zone of displayed image on the display screen of LCD1050b, occurred, so just implement to block the process of blocking in this zone with predetermined color, and the LCD control section by as image display portion demonstrates the image based on the later picture intelligence of the process of blocking on display screen.
In such a manner, even display screen is different on slenderness ratio or aspect ratio with the image pickup district, assign to implement to comprise by signal processing part and the pixel count matching process (slenderness ratio normalization) of the process of blocking on display screen, just can accurately and intactly demonstrate image based on the picture intelligence after the pixel count matching process.
Figure 17 has illustrated the pixel count that signal processing 103b had adjusting and pixel count matching process.
The left side of Figure 17 is the aspect ratio (N/M) in the image pickup district of CCD12a, and the right side of Figure 17 is the aspect ratio (n/m) of the viewing area of LCD1050b.
If shown in (a) part of Figure 17, two aspect ratios equate, so just, implement the pixel count adjustment process according to numeral, so that the vertical and horizontal figure unit number in the image pickup district of CCD is complementary with the vertical and Horizontal number of pixels of display screen, perhaps vertical the and Horizontal number of pixels of display screen can be complementary with the vertical and horizontal figure unit number in the image pickup district of CCD.Because the vertical and horizontal figure unit number in the image pickup district of CCD generally will be more than the vertical and Horizontal number of pixels of display screen, so graphic element by mixed C CD image pickup district horizontal (N) arrangement, implement the pixel count adjustment process, with the size that is adjusted to display screen (m * n).
Equally, if shown in (b) part of Figure 17, two aspect ratios are different, and wherein the lateral length in CCD image pickup district is greater than the lateral length of the display screen of LCD1050b, just implement pixel count matching process of the present invention according to numeral so.
Such as, when the array of the graphic element among the CCD is the honeycomb array, the horizontal graphic element that seems honeycomb arrangement is arranged in the horizontal direction in an orderly manner, and laterally the figure unit number is bigger, and the aspect ratio (N/M) in the image pickup district of CCD is greater than the aspect ratio (n/m) of display screen.
Therefore, just to carry out the pixel count matching process, be blended in transversely (horizontal direction) adjacent graphic element, to reduce horizontal figure unit number.
In the present embodiment, if vertically than M less than the LCD1050b display screen vertically than m (example (1)), just target image is presented in the display screen of LCD1050b so, the viewing area is not blocked, and the form with black surround shows on display screen.
And, if CCD vertically than M greater than the display screen of LCD1050b vertically than m (example (2)), just target image is cut off bottom and upper segment so, show between two parties.
In such a manner, obtaining the object that optical system obtains by the image of camera head resembles on the display screen that is displayed on LCD as full figure.Though adapt to the Horizontal number of pixels on the display screen of LCD for the horizontal figure unit number that makes the picture intelligence that CCD12a obtains, pixel count is regulated or the pixel count matching process is described in Figure 17, but, be used to regulate the elevational plot unit number of picture intelligence, pixel count adjustment process with the Vertical number of pixels on the display screen that adapts to LCD1050b, with the pixel count matching process of the Vertical number of pixels of elevational plot unit number that is used to mate CCD and display screen, implement possibly.
