Description

 The group of inventions relates to the field of photographic equipment, in particular to power supply devices and to digital cameras operating without rechargeable batteries or batteries.

 The algorithm (Fig. 8) describes the sequence of operations during operation of the power supply device of a digital camera (Fig. 1). The algorithms (Figs. 9, 10 and 11) describe the sequence of operations during operation of a digital camera (Fig. 2) from a digital camera’s power supply device 7 in the photographing modes, viewing the completed photo frame on the display, and transmitting the photo frame to the external device (s). The algorithm (Fig. 12) describes the sequence of operations during operation of a digital camera (Fig. 2) from an external power source in the transmission mode of the photo frame (s) to the external device (s).

 The power supply device of the digital camera (figure 1) can be performed on standard and specially manufactured products. In particular, power supply generation unit 3 on analog and digital electronic components, on-off elements 4 on mechanical switching devices, power storage unit 5 on capacitor-type elements, manual power generation unit 6 may be a power generator with a manual drive .

 A digital camera (figure 2) can be performed using various products: mechanical, electromechanical, electronic-mechanical, electronic and optical. Block 8 (figure 3) is made in the form of mechanical blocks and elements and, in particular, it can be used switches, buttons, springs, magnets, cables, gears and other products. Block 9, the circuit diagrams of which are shown in FIGS. 4 and 5, are performed on standard or custom chips and other elements, in particular, memory block 1 — on various chips, memory cards (Smart Media, Compact Flash, etc.), micro-winchesters etc., matching units 26 and 29 consist of standard elements: interface units 27 that transmit signals, for example, to a liquid crystal display 17, to a computer (USB, RS232C, IEEE 1394, etc.) and a television (PAL, NTSC, etc. .), and for the switch 28 can be used bus driver.

 An image to digital information converting unit 10 is shown in FIG. 6 and is based on standard elements, in particular, the color filter 30 can be performed on blue-green-red microfilter filters, element 31 on CCD, K-MOS or other matrices that perform the role of converting the image into an electrical signal, and the analog-to-digital converter 32 implemented on standard microcircuits.

 Shutter 11 can be made in several versions (A. I. Trachun, “A SLR camera as a system”, M .: “Art”, 1986.- 157 p., See p. 19-26), and can, in particular , consist of metal petals, curtains, lamellas or fabric dampers, as well as springs, gears, inertia drum or anchor control, in addition, electromagnets and various electronic components can be used in the shutter.

 The optical unit 12 consists of a number of standard elements, but may have a different implementation, which depends on the type of camera: SLR, rangefinder, etc. An example of the optical unit of an SLR camera is presented in the book: A. I. Trachun, “Mirror Camera as a System”, M .: “Art”, 1986.- 157 pp. (See pages 13-18). In any case, the optical unit 12 comprises a lens. In a specific case, a lens 33 (FIG. 7) is provided having, in particular, a focus adjusting ring 34 and a diaphragm adjusting ring 35.

 The control signal generation blocks 13 and the control signal block 14 can be performed on standard or custom microcircuits. Their implementation can be performed both on the hardware and on the firmware level.

 The group of elements 15 interruption and on-off is a set of both mechanical elements and electronic. This group contains, depending on the specific technical implementation of the blocks 9, the block 10 and the shutter 11, mechanical switches of electrical signals and digital microcircuits that transmit logic signals, as well as analog electronic elements. The inputs of digital microcircuits are fed with a logical “1” or “0” from the power supply device 7. The logical "1" or "0" is connected using mechanical switches controlled by blocks and controls 8. As a result, a digital code appears on the inputs of blocks 13 and block 14, specifying the program of work of these blocks.

 Elements 16 for manual setting of modes can be performed on the basis of several multi-contact switches, for example, rotary and push-button actions, and on transmission elements that provide connection or disconnection of electrical contacts in the group of elements 15 for interruption and on-off.

 Display 16 may be a liquid crystal display (PHOTO AND VIDEO magazine 9, 2002, p. 62).

 The power supply digital camera (figure 1) works as follows.

 Block 6 of the manual generation of electricity generates electricity, which is accumulated in block 5 of the electric energy storage. For the further operation of the digital camera, in particular for recording in the memory unit 1 of the photo frame converted into digital information, a response occurs - the on-off elements 4 are turned on, after which the electric power enters the power supply generation unit 3. This unit creates operating voltages of the power supply, in particular the memory unit 1 and the control unit 2 of the memory unit, which provides signals of the recording mode and the specific address of the memory unit 1. After recording the photo frame is triggered - off elements 4 on-off. This process is illustrated in the form of the algorithm in Fig. 8.

 Digital camera (figure 2) works as follows.

 There are several modes of operation of a digital camera: the photographing mode, the viewing mode of the photographed frame, the transmission mode of the photographed frame (information) to external (its) devices (o) using the digital camera’s power supply device 7, the mode of transmitting information to external (its) devices (o ) using an external power source.

 Moreover, for all modes, there are general principles of work.

 The power generation inputs of the power supply device 7 receive a command from the blocks and control elements 8, as a result of which electricity is generated in the device 7. In the case of connecting an external power source, electricity in the device 7 is not generated. The power supply device 7 and the blocks and control elements 8 transmit operating voltages and control digital codes, respectively, through a group of interrupt and on-off elements 15. This transmission is also regulated by elements 16 of the manual setting of modes. As a result, digital codes appear on the inputs of the control signal generation blocks 13 and the control signal block 14, specifying the operation program of these blocks, and accordingly, the operation of the memory and matching block 9, the block 10 for converting the image into digital information, and the display are determined.

 If the shutter 11 is made mechanical, then its control is carried out only by blocks and control elements 8 (the dashed line in figure 2 is conditionally absent), if the shutter is electromechanical or electronic-mechanical, then it is necessary to supply power to the shutter 11, which is produced by the device 7 through a group of elements 15 (the connection shown in dotted lines in FIG. 2 exists).

 Photographing mode (described by the algorithm in Fig.9).

 In this mode, the shutter 11 operates, which, as mentioned above, can be mechanical, electromechanical, and electronic-mechanical. For the last two options, the supply voltage to the gate is required. Therefore, as already mentioned above, in Fig. 2, the connections connecting the group of interruption and on-off elements 15 and the shutter 11 are indicated by a dotted line and correspond to the presence of electromechanical and electronic-mechanical shutters. For the mechanical shutter, there are no dashed links.

 The photographing mode is set using the elements 16 of the manual mode setting. In this case, using the elements 16, the following shooting parameters are set: the size of the photo frame (in Kb or Mb), the recording format (for example: TIFF, RAW, JPEG), the size (resolution) of the image (usually in millions of pixels), sensitivity (for example, in units ISO), white balance and other parameters depending on the technical implementation, for example: setting and adjusting color, shooting with a self-timer, etc. As a result, the following modes are set in the group of interrupt and on-off elements 15: permission is issued for supplying power to the memory unit 1 included in the memory and coordination unit 9 (depending on the technical implementation of the unit 9 - see FIGS. 4 and 5), to a block 10 for converting an image into digital information, to blocks 13 for generating control signals, to a block 14 of control signals and to a shutter 11, if it is made in the form of an electromechanical or electronic-mechanical type.

 Blocks 13 of the formation of control signals are pre-set to issue recording signals of the memory unit 1 included in the memory unit 9 and coordination (depending on the technical implementation of the blocks 9); block 14 of control signals is pre-set to set a specific size of the photo frame, recording format, image size (resolution), sensitivity, white balance and other necessary parameters.

 On the lens 33, the ring 35 sets the aperture.

 Using the blocks and control elements 8, the shutter speed is set, the power supply device 7 is activated through the inputs of the power generation, in particular the manual power generation unit 6, the latter is accumulated in the electric energy storage unit 5. At the same time, the shutter 11 is cocked (if the shutter is mechanical, then only with blocks and elements 8, if it is electromechanical or electronic-mechanical, then the supply voltage is supplied from the power supply device 7 through the group of elements 15).

 Through the optical unit 12 using the ring 34 of the lens 33 focuses the focal length of the subject.

 The blocks and control elements 8 issue a turn-on command to the on-off inputs of the power supply device 7, allowing the supply of operating power voltages from the power supply device 7 (via block 3) to the group of interrupt and turn-on-turn off elements 15. Blocks and control elements 8 commute in the group of elements 15 interruption and on-off operating voltage and preset photo parameters using the elements 16 of the manual installation.

 The blocks and controls 8 open the shutter (also by means of a group of elements 15, if the shutter is electromechanical and electronic-mechanical); from the lens 33 to the block 10 the image is converted into digital information, which is stored by the memory unit 1 (depending on the implementation of the matching blocks 26 and 29 in block 9 - see figures 4 and 5). In the first case, the coordination unit 26 contains a switch 28 and information is recorded on the memory unit 1 through a switch 28 controlled through a group of elements 15, in the second case, the coordination unit 29 does not have a switch, since the memory unit 1 has a separate input to which information is supplied directly from block 10. Blocks and controls 8 close the shutter 11 depending on the set shutter speed, and then turns off the power supply by the power supply device 7 (using elements 4).

 The viewing modes of the photographed frame and the transmission of the photographed frame (information) to the external device (s) using the power supply device 7 of the digital camera. These two modes are distinguished by the installation in the elements 16 of the manual setting of the modes and the formation of the output information for the external (its) devices (a) (they are described by the algorithms in Figs. 10 and 11, respectively).

 The mode of viewing the photographed frame or the mode of transferring it (information) to external (its) devices (o) is set using the elements 16 of the manual mode setting. At the same time, using elements 16 and blocks and control elements 8, through the group of elements 15, the ability to supply power to block 10 and block 14 is turned off, switching is prepared to generate control signals on blocks 13 for reading information from memory block 1 (depending on technical implementation) - see Fig. 4 and 5). In the first case, the output of the matching unit 26 contains a switch 28 and the output of information from the memory unit 1 is carried out through a switch 28 controlled through a group of elements 15, in the specific case for transmitting information to the interface units 27. In the second case, the coordination unit 29 does not have a switch, since the memory unit 1 has a separate output connected directly to the interface blocks 27, which are a coordination unit 29.

 The difference between the viewing modes of the photographed frame and the transmission of the photographed frame (information) to the external device (s) consists in the operation of the interface units 27 (see Figs. 4 and 5). In the first case, only the interface unit that transmits information to the display 17 functions, and in the second case, interface units that transmit information to external (its) devices (o) also function. In accordance with this, commands are issued from the group of elements 15 to blocks 13 to generate the corresponding control signals.

 Using the blocks and control elements 8, the photographing mode is turned off, the power supply device 7 is activated through the inputs of the power generation (block 6). Electricity is accumulated in device 7 (in block 5), then block 8 gives a command through the on-off inputs of device 7 (elements 4) to supply power, after which device 7 (block 3) generates operating voltages that are supplied to a group of elements 15. The group of elements 15, in turn, transfers the operating voltage to block 9, blocks 13 and display 17, and also transfers the signals prepared by mechanical switching to blocks 13, which supply control signals to block 9.

 As a result, in the viewing mode of the photographed frame, the image is displayed on the display, and in the mode of transmitting the photographed frame (information) to external (its) devices (o), the information is transmitted to the outputs for connecting external (its) devices (a), and the corresponding picture. By applying a manual signal to the power off input of the power supply device 7 (to element 4), this process can be stopped and then started again, changing the number of the photo frame using blocks and controls 8 (25 frames counter).

 The mode of transmitting information to external (its) device (s) using an external power source (described by the algorithm in FIG. 12).

 The installation of the mode of transmission of information to external (its) device (s) using an external power source using the elements 16 of the manual mode settings. Moreover, using the elements 16 and the blocks and control elements 8 through the group of elements 15, the ability to supply power to the block 10 and block 14 is turned off, a switching group of elements 15 is prepared to generate control signals on the blocks 13 for reading information from the memory unit 1 (depending from technical implementation - see figures 4 and 5). In the first case, the coordination unit 26 contains a switch 28 and information is output from the memory unit 1 through a switch 28 controlled through a group of elements 15, in the particular case for transmitting information to the interface units 27. In the second case, the coordination unit 29 does not have a switch, and the memory unit 1 has a separate output connected directly to the interface blocks 27, which are a coordination unit 29.

 An external power source is connected to the power supply device 7 through external inputs for connecting an external power source (elements 4). (In this case, the first and third inputs of element 4 are automatically disabled). The device 7 generates operating voltages (block 3) and, through a group of elements 15, transmits operating voltages to block 9, blocks 13 and display 17. The group of elements 15 also transmits signals prepared by switching blocks and control elements 8 to blocks 13, which control block 9.

 As a result, in the mode of transmitting information to external (its) devices (o) using an external power source, information is transmitted to the outputs for connecting external (its) devices (a), and the corresponding image is displayed. By applying a manual signal to the power-off input of device 7 (to element 4), this process can be stopped and then restarted.

 Blocks and controls 8 (figure 3) work as follows. Using elements 18, the shutter speed is set (photographing mode) or the photographing mode is blocked (viewing mode of the photographed frame, transmission mode of the photographed frame (information) to the external device (s) using the digital camera’s power supply device 7, information transfer mode to external (s) device (s) using an external power source).

 The counter 25 frames with the help of the reset input to the initial state is set to the initial state if the photo block is not recorded in the memory unit or if existing photo frames need to be erased. The counter 24 frames transmits the code of the frame number to the block 19 of the actuators, which in turn prepares the switching of logical "1" and "0" at the inputs of the logical elements of the group of elements 15, which transmits control information to the blocks 13 for subsequent selection of the cell address of the memory block, to record or view a photo frame. Those. Using the inputs of adding and subtracting the frame number, you can manually select the memory block cell address for recording or viewing a photo frame.

 When setting the photographing mode, i.e. setting a specific shutter speed using the elements 18, the platoon mechanisms of block 21 are cocked by the platoon lever 22, the holding time is set in block 20. The actuators of the actuator unit 19 are activated, controlling the shutter 11 and the switches included in the group of elements 15. If necessary, the counter 25 frames is reset by manually pressing the reset input to the initial position. When cocking the cocking lever 22, the cocking unit 21 transmits the movement to the power supply device 7 (block 6) to generate electricity. In addition, block 21 cockes the shutter 11 and block 20, based on a mechanical timer. Block 21 also switches the frame number in the counter 25 frames. When the shutter button 24 is pressed, the trigger 23 is triggered, which gives permission for the operation of the block 19 of the actuators, which turn on the power supply via the on-off inputs of the power supply device 7 (elements 4), commute the group of elements 15 and open the shutter 11. At the end of time The shutter speed unit 20 issues a command to the actuator unit 19, which closes the shutter 11 and turns off the power supply via the on-off inputs of the power supply device 7 (element nt 4).

 When setting the viewing mode of the photographed frame and the transmission mode of the photographed frame (information) to the external device (s) using the digital camera’s power supply device 7, the photographing mode is blocked by the elements 18. In this case, the cocking of the shutter 11 and block 20 by the block 21 of the cocking mechanisms , the actuators of the block 19 that control the shutter are turned off. The actuators of block 19 controlling the group of elements 15 are also set to a certain state. Thus, the power supply to the group of blocks 10 and block 14 is turned off and, on the contrary, the power is turned on and all control signals are sent to blocks 9, blocks 13 and display 17. The cocking lever 22 is cocked, the platoon unit 21 is triggered, the power supply device 7 generates electricity. When the shutter button 24 is pressed, the trigger 23 is activated and the actuator block 19 turns on the power through the device 7 (elements 4), and also commutes the group of elements 15 to provide power and operation of the block 9, blocks 13 and the display 17.

 When setting the transmission mode of information to external (its) devices (o) using an external power source, the photographing mode is blocked by the elements 18. At the same time, the elements 18 include actuators of the block 19, which through the device 7 provides continuous power supply through the group of elements 15 on block 9, blocks 13 and display 17.

 The group of elements 15 interruption and on-off works as follows.

 The group of elements 15 transmits both the operating voltage of the power supply and the control information to block 9, block 10, blocks 13, block 14, display 17, and also to the shutter 11, if the latter is electromechanical or electronic-mechanical. Operating power supply voltages are transmitted directly through mechanical switches from the power supply device 7. The control information at the outputs of the group of elements 15 is formed by mechanical switching of the logical "1" and "0" at the inputs of the elements (microcircuits) included in the group of elements 15. Logical "1" and "0" are also transmitted by the power supply device 7. These switches are carried out by blocks and controls 8 (in particular, block 19), as well as according to the settings made by the elements 16 of the manual mode settings.

 As a result, the proposed power supply device of the digital camera provides the digital camera at any time, it does not require recharging the power device or its replacement during discharge. The life of the power supply device is increased, which does not depend on the discharge time of the battery or batteries, but on the technical implementation of the power supply units, the time between failures, which for electromechanical and electronic devices is significantly higher than the life of the batteries or batteries. The proposed digital camera using this power supply device, together with mechanical controls, has more reliable operation in difficult climatic conditions, including low ambient temperatures, compared to a digital camera with a conventional power source and fully electronic control.
