Below in conjunction with accompanying drawing most preferred embodiment of the present invention is described.
Fig. 1 is that it comprises according to the block diagram of the video processor of first embodiment of the invention: the photographic camera part 1 of title, camera lens 2, aperture 3, shutter 4, shutter release button 5, imaging device 10, circuit part 20 as title, camera signal treatment circuit 21, mould/number conversion circuit 22, frame memory 23, image compression and expanded circuit 24, system, control circuit 25, D/A switch circuit 26, video encoder 27, interface circuit 28, immediate access device 29, serial communication interface circuit 30, serial line interface terminal 31, video output terminal 32, and timing generator 33.
Below its work will be described.The visual scioptics 3 of object as shown in the figure are sent to shutter 4, and luminous flux is by the aperture adjustment.In response to the signal from shutter release button 5, the speed that shutter 4 is set with the system controller of photographic camera 1 passes to imaging device 10 with light.Light from lens 2 focuses on the imaging device 10.Be associated with the light that incides photographic camera, so far, all processes all are well-known.
Imaging device 10 converts the optical image of incident to TV signal frequently.According to from the timing signal that reads timing generating circuit 33, that will be launched into camera signal treatment circuit 21, sequentially read this TV signal frequently.Treatment circuit 21 is known camera signal treatment circuits and comprises gain control circuit, gamma compensated circuit etc.After this, to be stored in the digital signal in the frame memory 23 after vision signal is converted to by A/D converter.
The signal that is stored in the memory 23 is sent to D/A converter 26 by branch operation, reverts to analog signal, such as converting vision signal to by video encoder, for example is suitable for the TSC-system signal of television monitor, exports from outlet terminal then.Terminal 32 is connected with liquid crystal display monitor central monitoring system or electronic viewfinder, just may supervises and show the image of hunting.
Image compression circuit 24 sequentially reads vision signal from frame memory 23, then with the compression method of Joint Photographic Experts Group regulation, for example compress this vision signal according to predetermined format.The vision signal of compression is stored in the immediate access device 29 by interface circuit 28.Because single immediate access device chip has upper limit capacity, this immediate access device 29 comprises several memory chips that are accumulated in together, with the increase capacity.For example in the 69-75 page or leaf of " Electronic Design " that Penton publishing house published August 22 in 1994, this kind technology has been described.
Otherwise, also can convert serial signal to by the vision signal of compressor circuit 24 compressions, to export from serial signal outlet terminal 31 by serial communication interface 30.Utilize terminal 31, comprise that the main body of photographic camera 1 and circuit part 20 also can be used as the digital encoder of vision signal.
In playback, there are two kinds of input routes to use.First route is the passage from memory, and second route is from the route of external equipment by serial terminal 31.Contrast recording operation in two kinds of routes, signal is all got back to expanded circuit 24.In expanded circuit 24, for incoming video signal is determined compression method, so that use the method corresponding with the compression method of determining to come spread signal, therefore, the signal of expansion focuses in frame memory 23.Then, with this signal as vision signal, deliver to terminal 32 by D/A converter and video signal coding 27.
A kind of signal processing route has been described.In this was described, in order to simplify description, A/D converter circuit 22 was arranged to the following stages of camera signal treatment circuit 21., even A/D converter circuit 22 is placed in the circuit 21, there is not the difference of essence yet.
To describe below shutter 4 and imaging device 10 read regularly between synchronously.For example can following foundation synchronous.Obtain shutter trigger signal from the photo-optics pusher side, be provided to timing generating circuit 33 or system, control circuit 25 then.When using shutter regularly in this mode, just need provide interface circuit, with output signal (i.e. the shutter trigger signal that cooperates with shutter section) at the photo-optics pusher side.That is to say,, also need interface circuit, with from photograph pusher side input signal in optical image converter therefor one side.
The advantage of another kind method is: when shutter 4 was opened, the light quantity that incides imaging device can significantly increase.Under the situation that adopts the light quantity to incide imaging device significantly to increase, can realize Electrofax, and change conventional photographic camera that this is different with the above-mentioned situation of utilizing the shutter timing.In this case, used a kind of method directly to monitor the light quantity that incides imaging device.Perhaps use following method.Usually, in this imaging device,, remain in the electric charge on this device and have and the electric charge of the polarity of the opposite charge that this is residual discharges from this imaging device as video information.Monitor the flow velocity of discharge charge, just can detect the light that enters imaging device with non-direct mode.
Next, specifically describe with reference to figure 2,3,4 and 16 and finish this method of operating.Fig. 2 is the schematic diagram according to the optical imagery transducer of video signal preprocessor of the present invention.This transducer comprises planar substrates 50, the signal terminal 52a-52g that is fixed with imaging device on it and guarantees mechanical strength, the socket 52 that is used to insert terminal 52a to 52g, indicates the part 54 and the circuit access part 55 of the sensitivity of imaging device as the billy 53 of drum part, as the equivalent value of silver halide photographic films.
In this embodiment, the planar section 50 that forms the optical converter part separates with drum shape part 53, and the centre is inserted with and comprises and be used to the socket assembling and be electrically connected and the coupling part of terminal.In the structure that monolithic forms, planar section 50 and drum shape part 53 are formed on the piece, and the present invention also can implement in this case, and without any problem.When the needs vision signal was stored in the circuit part, the optical converter of monolith forms partly needed a terminal from its outputting video signal.Consider the profile of optical converter part, needing for example provides a lead-out terminal at drum shape upper surface partly., in this embodiment, when planar section 50 separates with drum shape part 53, obtain to be stored in circuit part vision signal terminal and can be arranged in connector part or shared bonder terminal from the terminal that imaging device is entered as image signal.Therefore, needn't lead-out terminal be set at the upper surface of drum shape part.In playback, the user only need remove this billy 53, and the terminal of the blank space by being arranged on the coupling part is connected to playback unit with this container 53.Compare with monolith forms, only used billy 53, so structure is littler, the user is more convenient.
In order to guarantee mechanical strength, only need substrate 50 to have the thickness of about 1mm.Usually, photographic camera covers thereafter has a planar spring, so as the pushing film, the Hookean region of the 1mm to 2mm that therefore just has an appointment.Because this Hookean region is used to the insertion of substrate 50, this bonnet just can be closed suitably.
Fig. 6 is the outside drawing of second embodiment of the invention, and it is with shown in Figure 2 different.The part identical with Fig. 2 represented with identical label, just do not described. Label 56a and 56b represent the receiver side and the inserting side of connector respectively.
The structure different with Fig. 2 is to provide the pin-type connector between substrate 50 and container 53.In the figure, in order to simplify drawing, 6 connector pins have only been shown.In fact, as described in Figure 2, the pin more than 10 is arranged.
On substrate or by the substrate arrangement, lead is arranged, will lead to terminal 52A to 52H and 56A from the traction signal line and the drive controlling line of imaging device 51.As shown in Figure 6, this terminal can be arranged on other flat board, rather than has arranged the flat board of imaging device 51, and promptly terminal 56A is set on the side surface of thickness direction, and terminal 56B is arranged at the position opposite with terminal 56A.
, as mentioned above, the thickness of substrate 50 can insert the space of loading the traction film.Therefore, on this thickness, just be difficult to place connector, and, for this thickness, also be difficult to the coupling part and obtain enough intensity.Therefore, in this embodiment, connector 52a to 52g be arranged at the surperficial identical or opposite surfaces that is fixed with imaging device on.When constituting the socket 52h of covering connector 52a to 52g, this connector has just obtained enough intensity.
For example, under the situation of online type imaging device, comprise holding wire and drive controlling line, only need 14 lines altogether, promptly a line is used for from the imaging device output signal, article four, line is used for the vertical drive imaging device, two lines be used for horizontal drive it, 7 lines comprise that control line is (such as reset line and biasing and power line.By 7 terminals that comprise terminal 52a to 52g shown in Figure 7 are set on the opposition side of this substrate, just can implement at an easy rate.In this connects, although having 14 terminals altogether, substrate 50 promises to undertake type imaging device between line, for the imaging device of other type, number of terminals is not restricted to 14.Because connector 52h has the width that equals the 35mm film, even when settling this terminal with the pitch of 1mm, can easily settle maximum 17 terminals on each surface.Therefore, even when using other type image forming apparatus outside this embodiment,, and there is not any problem for substrate 50 and socket 52h can connect.
The size of billy 53 is that it can be installed in the part of loading 135 type spool boxs.As shown in figure 14,135 type spool boxs have about 25mm diameter, and therefore, when billy 53 had the diameter of about 25mm, it can be installed in this part.In addition, when billy 53 had maximum height 47mm, this container 53 can be installed in this part., photographic camera includes the backrush part of backrush film, and this part can not be thrown off photographic camera.Therefore, only need this billy to have 37mm height or the prior groove 53 that is provided with on the part of this container, the backrush part of backrush film just enters and contacts with this container.Groove 53 is to be provided with at the upper surface of billy.When groove 53 had 11.5mm diameter and about 7.2mm degree of depth, this container did not partly contact with the backrush of backrush film.When needs increase the inner space of billy 53, must carry out little change at the photograph pusher side.When the structure of the backrush of backrush film part is to want expansible and can contact the time, when pressure being arranged thereon, this part just rises, and does not just need to be provided with groove 53, therefore, the inner space of billy 53 has increased.
On the 35mm film, the sensitivity of indication is arranged usually, by reading this indication, camera can not carry out exposure work best.Or in the application's Electrofax of the present invention, when indicating area 54 being set in the precalculated position, the sensitivity of the film of this photograph function identification and this optical converter part correlation, state that therefore can be best carries out exposure.
Because substrate 50 can at random substitute, and can be imaging device a lid is set, and removes the imaging device of substrate 50 and prevents that dust from entering this imaging device with protection.In addition, because bonnet can freely open and close, this lid can be used for also preventing that dust etc. from entering imaging device.This lid is so to constitute, and promptly when photographic camera was installed on the substrate, this lid was opened automatically.
With reference to figure 3 and 14, will provide an embodiment below, wherein the circuit part 20 of Fig. 1 is installed in the container 53 of Fig. 2.
Figure 14 is the schematic diagram of 35mm film, it comprises: box 231, long cover 232, short cover 233 as the box further groove, the diameter 234 of box 231, the box upper edge surface is to the distance 235 between the short cover protrusions, the height 236 of short cover protrusions, from the upper surface of box to the distance 237 the lower limb surface of long cover 232.
According to JIS K7519 " 135 type spool box ", the diameter 234 of box 23 is about 25nm, and height 237 is about 47mm, mostly is 7.2mm most to the short degree of depth 235 of overlapping protrusions.Protruding height 236 does not have concrete regulation., according to the result of actual measurement, be about 15mm with respect to the degree of depth of lacking the upper edge surface of overlapping.Therefore, in billy 53, the height of this container 53 can be set to 47mm., by height 237 (47mm) are deducted 15mm and promptly become 37mm, can obtain diameter wherein and be 25 usable range.
Below, with reference to Fig. 3, will specifically specify the method for the internal structure of billy 53 according to top numbers illustrated.
In Fig. 3, include circular substrate 60a to 60e (diameter of each 24mm that all has an appointment) and strutting piece 61a and 61b (they support circular substrate and are presented in the communications electronics signal).Container 53 outer wall thickness own can be ignored., the thickness of supposing each strutting piece 51a and 51b is 0.5mm, and the diameter of each substrate 60a to 60e is about 24mm.
For example, obtainable 8 LSI constitute on circuit part 20 maximum available markets of Fig. 1.When 8 LSI of maximum usefulness, just these LSI may be installed on two surfaces of four substrates.System controller is the form of big LSI.For this controller, for example can adopt the chip microprocessor H8/3042 sequence of Hitachi.According to Hitachi, Ltd disclosed " H8/3042 sequence hardware handbook (1993) ", this microprocessor is the form of 100 pin planar package, and the mounting portion is of a size of 14mm, comprise the edge and the lead-in wire, on one side full-size be 16mm.
Fig. 4 is the schematic diagram that is installed in the LSI on the substrate 60a.Label 62 expression LSI.Diameter is that the length that connects foursquare each limit in the disk of 24mm is 17.0mm.Edge length be 16 or littler microprocessor sequence H8/3042 sequence can be installed on the disk 60A, and enough lead-in wire zones are arranged.When LSI need be bigger than top LSI, only need be at these semiconductor chips of close installation that come up such as devices such as net arrays.Adopting the circuit structure of stacked die also is available method.
Remaining one is used to install discrete device in five disks, such as the output driver of signal processing circuit 21 and video encoder 27.Also can in a chip, constitute camera signal processor circuit 21 and video encoder 27.In this case, these parts can be installed on five substrates fully.
Under this state, the thickness of each substrate is 1mm or littler, and the height of LSI is actual to be 1.2mm.The highest parts are capacitors, and it highly is 5mm.Suppose that each LSI needs such electric capacity.Just may only arrange this LSI in a side of each substrate.Because each substrate has 7.2mm or littler thickness, therefore, by simple computation, the thickness of five substrates is 36mm, and it is enough that above-mentioned height gage is decided to be 37mm.
Although can on five substrates, consider the method for various wirings,, just may reduce the wiring in strutting piece 61a and 62b when the memory 29 that needs most control line and interface circuit 28 are positioned in two an of substrate when surperficial.For other circuit, be practical along the signal flow wiring.By way of parenthesis, although in Fig. 3, only shown two strutting pieces, can increase strutting piece corresponding to wiring.
Although the substrate shown in Fig. 3 and 4 has circle, as shown in Figure 5, the profile of substrate also can be positive octahedral shape.Fig. 5 is that LSI is installed in the embodiment on the substrate with shape different with Fig. 4.The difference of this example and Fig. 4 is that contour substrate becomes octahedral shape from circle, and the quantity of strutting piece is 3.
The positive octahedral shape substrate of label 65 expressions, 66a to 66c represents strutting piece, 67 is LSI.So arrange LSI, to such an extent as to each angle of LSI is all relative with per two summits of substrate 65, just a square may be installed in polygon-octagonal, this square has maximum size, can go between in this square.The diameter of supposing the circuit in including the substrate of strutting piece shown in Figure 5 is 25mm, and strutting piece 66A to 66C has the thickness of 0.5mm, and so, each edge of LSI has the length of 17.0mm or littler.Therefore, the edge be 16.0 or littler LSI can be installed in the substrate 65.For circular substrate, when this substrate is installed in the bulge, can expect to obtain largest usable region., when the positive octahedral shape of being shaped as of substrate, it is simpler than circular substrate to operate.
Among the strutting piece a to c any one connects with the connector 52h of Fig. 2.It will be appreciated that substrate 65 has foursquare outward appearance, rather than octagon.
Difform film also might appear having in the future.Container 53 among Fig. 2 can design according to this shape.When the comparable present 35mm spool box of this film hour, can design according to this little shape spool box, promptly several circuit of circuit part 20 are concentrated among the LSI.
In the description of Fig. 1, can obtain control signal from the photo-optics pusher side, such as the signal relevant with the shutter trigger., for example also can arrange to be used for the connector of this purpose in the bottom surface of container 53; And, utilize strutting piece shown in Figure 5, the connector outside the connector 52h or contact can be arranged in the side of container 53.
As mentioned above, according to the present invention, equal in the container of diameter of 135 type spool boxs of JIS K 7519 regulations because signal processing circuit part can be collected in diameter, Electrofax can constitute with the imaging device in the focusing board that is arranged on photographic camera.Conventional camera can be used as Electrofax work, and does not want any change.And for example, when utilizing above-mentioned shutter trigger signal, as long as by draw several control lines just can realize Electrofax simply from photographic camera, this can significantly reduce the cost of exploitation Electrofax.When interface being set, only need to change electronic circuit in this camera side.This is simple modification, therefore also can not cause any cost problem in this case.In other words, the required all the time shell of Electrofax, shutter control circuit, view finder can be with representing in the photographic camera, and therefore, development cost reduces.And owing to as long as the film part that circuit part and imaging device part 4 are inserted in photographic camera just can be used Electrofax, just can realize two kinds of camera-enabled with identical shell, this has just expanded usability.
In addition, the information of the data of being handled by photographic camera can obtain by connector.For optical film, the user must determine what whether these data needed in addition in exposure work.In Electrofax, data are as the relevant information records of recording picture.Therefore, also provide the convenience of this respect, promptly whether the user can select these data to occur at playback time.
Figure 15 is the schematic diagram of one embodiment of the present of invention, the figure illustrates a concept nature method of the image that playback absorbs in Fig. 1 embodiment.
