<First Embodiment>
FIG. 1 shows a block diagram of a digital camera 10 and a schematic configuration of an environmental load calculation system including a personal computer 1 connected to the digital camera 10 and an external information environment DB 2. The digital camera 10 includes a camera body 10b and a lens unit 10l that can be attached to and detached from the camera body 10b. The lens unit 101 includes a photographing optical system 13 including a photographing lens 14 and a diaphragm 15, and a driving unit 152. The taking lens 14 is composed of one or a plurality of lenses, for example, a lens having a single focal length (fixed focus).

  The subject image formed on the light receiving surface of the CCD 118 via the photographing optical system 13 is converted into signal charges of an amount corresponding to the amount of incident light by each sensor. The signal charge accumulated in this way is read out by a CCD drive pulse applied from the CCD drive circuit 120 and is sequentially output from the CCD 118 as a voltage signal (analog image signal) corresponding to the signal charge.

  The CCD 118 is provided with a shutter drain via a shutter gate, and the accumulated signal charge can be swept out to the shutter drain by driving the shutter gate with a shutter gate pulse. That is, the CCD 118 has a so-called electronic shutter function that controls the accumulation time (shutter speed) of charges accumulated in each sensor by the shutter gate pulse.

  The signal read out from the CCD 118 is subjected to correlated double sampling (CDS) processing in the CDS circuit 122 and color separation processing into R, G, B color signals, and the signal level of each color signal is adjusted.

  The image signal that has undergone the predetermined analog signal processing is added to the A / D converter 124, converted into R, G, and B digital signals by the A / D converter 124, and then temporarily stored in the memory 126. Stored.

  A timing signal generation circuit (TG) 128 provides appropriate timing signals to the CCD driving circuit 120, the CDS circuit 122, and the A / D converter 124 in response to a command from the CPU 130. Each circuit generates a timing signal. It is driven in synchronism with a timing signal applied from the circuit 28.

  The CPU 130 is a control unit that performs overall control of each circuit of the digital camera 10, and includes a gain adjustment circuit 134, a gamma correction circuit 136, a luminance / color difference signal processing circuit (referred to as a YC processing circuit) 138, and compression / decompression via a bus 132. The circuit 140, the card interface 144 of the memory card 142, the display driver 148 that drives the LCD 22, the image conversion circuit 146, the communication unit 159, and the like are connected.

  In addition, a status display 20, a power consumption measurement unit 50, a nonvolatile memory 157, and a power button 25 are connected to the CPU 130.

  The status display 20 displays various settings, usage modes, states, and the like of the digital camera 10.

  The power consumption measuring unit 50 measures the power consumed by the lens unit 10 l from the power source 30 via the camera body 10 b or the digital camera 10 when the digital camera 10 is used. The power consumption is the power-on time, the power consumption per unit time of each operation mode (eg, shooting mode, playback mode), the number of each operation (eg, recording operation) and the power consumption per time. , Etc. There may be many types of lens units 10l instead of one.

  The nonvolatile memory 157 stores a control routine program to be described later, an environmental load calculated from the power consumption measured by the power consumption measuring unit 50, and other data. Details of the environmental load data will be described later.

  The CPU 130 controls the corresponding circuit block based on the input signal from the operation switch 38, and controls the zooming operation, automatic focus adjustment (AF) operation, automatic exposure adjustment (AE), and the like of the photographing lens 14. .

  The operation switch 38 includes camera mode selection means, zoom operation means, and other various input means. These input means have various forms such as switch buttons, dials, and slide-type knobs. There is also an aspect in which a setting menu or a selection item is displayed on the screen of the touch panel or the liquid crystal monitor display unit, and a desired item is selected with a cursor. . Although the operation switch 38 is disposed on the camera body 10b, the remote controller can be separated from the camera body as a remote control transmitter.

  The CPU 130 performs various calculations such as a focus evaluation calculation and an AE calculation based on the image signal output from the CCD 118, and based on the calculation, driving means (for example, an AF motor or an iris motor) for the photographing lens 14 and the diaphragm 16. Etc.) 52 is controlled to move the focus lens to the in-focus position, and the aperture 15 is set to an appropriate aperture value.

  For example, a contrast AF method in which the focus lens is moved so that the high frequency component of the G signal is maximized is employed for the AF control. In the AE control, the subject brightness (shooting EV) is obtained based on the integrated value obtained by integrating the R, G, and B signals of one frame, the aperture value and the shutter speed are determined based on the taken EV, and the driving unit 152 is operated. The aperture 15 is driven via the electronic shutter, and the charge accumulation time of the CCD 118 is controlled by the electronic shutter so that the determined shutter speed is obtained. Therefore, only by directing the photographic lens 14 of the digital camera 10 toward the subject, optimal exposure adjustment is performed and focusing is automatically performed.

  At the time of shooting recording, when the release button 18 is “half-pressed”, the above-mentioned photometric operation is repeated a plurality of times to obtain an accurate shooting EV, and the aperture value and shutter speed at the time of shooting are finally determined based on this shooting EV. To do. Then, the aperture 15 is driven so that the aperture value finally determined when the release button 18 is “fully pressed”, and the charge accumulation time is controlled by the electronic shutter so that the determined shutter speed is obtained. In addition to the method of controlling AE and AF based on the image signal acquired from the CCD 118, a well-known photometric sensor, a distance measuring sensor including an AF light projecting / receiving sensor, or the like may be used.

  The data output from the A / D converter 124 is stored in the memory 126 and added to the integrating circuit 160. The integration circuit 160 divides the photographing screen into a plurality of blocks (for example, 64 blocks of 8 × 8), and performs an integration calculation of the received G signal for each of the plurality of blocks. Note that the luminance signal (Y signal) may be generated from the R, G, and B data, and the luminance signal may be integrated. Further, the integrating circuit 160 can also be used as an AE arithmetic circuit. Information on the integrated value (calculation result) obtained by the integrating circuit 160 is input to the CPU 130.

  Based on information from the integration circuit 160, the CPU 130 calculates an evaluation value E of the photographic screen according to a predetermined algorithm, and determines a gain value (amplification factor) in the gain adjustment circuit 134 using the obtained evaluation value E. The CPU 130 controls the gain amount in the gain adjustment circuit 134 according to the determined gain value.

  The R, G, B image data stored in the memory 126 is sent to the gain adjustment circuit 134 where it is amplified. The amplified image data is subjected to gamma correction processing in the gamma correction circuit 136 and then sent to the YC processing circuit 138, where the RGB data is converted into luminance signals (Y signals) and color difference signals (Cr, Cb signals). Converted. Note that the CPU 130 can also perform white balance processing and the like as necessary.

  The luminance / color difference signal (abbreviated as YC signal) generated in the YC processing circuit 138 is written back to the memory 126. The YC signal stored in the memory 126 is supplied to the display driver 148, converted into a predetermined signal (for example, an NTSC color composite video signal), and output to the LCD 22. A liquid crystal display or other display device capable of color display is used for the LCD 22. The LCD 22 may be a YC signal input compatible type or an RGB signal input type, and a driver corresponding to the display device is applied.

  The image data is periodically rewritten by the image signal output from the CCD 118, and a video signal generated from the image data is supplied to the LCD 22, whereby the image captured by the CCD 118 is converted into a moving image (live image) in real time. Alternatively, although not in real time, the image is displayed on the LCD 22 as a substantially continuous image.

  The LCD 22 can be used as an electronic viewfinder, and the photographer can check the shooting angle of view with the display image on the LCD 22 or the viewfinder. In response to a predetermined recording instruction (shooting start instruction) operation such as an operation of pressing the release button 18, capturing of image data for recording is started.

  When the photographer inputs a shooting / recording instruction from the operation switch 38, the CPU 130 sends a command to the compression / expansion circuit 140 as necessary, whereby the compression / expansion circuit 140 converts the YC data on the memory 126 into JPEG or another predetermined format. Compress according to The compressed image data is recorded on the memory card 142 via the card interface 144, for example.

  The digital camera 10 of the present embodiment uses a memory card 142 as means for storing image data. Specifically, for example, a recording medium such as an xD picture card is applied. The form of the recording medium is not limited to the above, and various forms such as a PC card, a micro drive, a multimedia card (MMC), a magnetic disk, an optical disk, a magneto-optical disk, and a memory stick are possible. Corresponding signal processing means and interfaces are applied.

  In the reproduction mode, the image data read from the memory card 142 is decompressed by the compression / decompression circuit 140 and output to the LCD 22 via the display driver 148.

  The CPU 130 is connected to the communication unit 159 via the bus 132. The communication unit 159 is an interface for communicating with an external environmental load information database (external DB) 2 through a user's personal computer 1 (PC) or a communication network such as the Internet. For example, USB (Universal Serial Bus), IEEE 1394, etc. The interface can be used. The CPU 130 can exchange information with the external DB 154 via the communication unit 159.

  Next, data regarding environmental loads will be described.

The nonvolatile memory 157 is provided with an environmental load table 150 that stores data on environmental loads. The environmental load table 150 includes a manufacturing environmental load E _PR generated when the digital camera 10 is manufactured (manufacturing stage), a distribution environmental load E _PD generated when the digital camera 10 is transferred from the manufacturing factory to the user (distribution stage), Use environmental load E _US generated when the camera body 10b is used (use stage), waste environment load E _RJ generated when the camera body 10b is discarded (discard stage), and integrated value of the environmental load of the digital camera 10 so far _Esum , total environmental load E _T throughout the life cycle of the camera body 10b, environmental load information of parts that can be mounted on the camera body 10b, such as the lens unit 10l and the power supply 30 (primary battery, secondary battery, AC power supply) Is remembered. The integrated environmental load E _sum is the _sum of the production environmental load E _PR , the distribution environmental load E _PD , and the previous use environmental load E _US , and the total environmental load E _T is the production environmental load E _PR , logistics The total is the environmental load E _PD , the use environmental load E _US , and the disposal environmental load E _RJ . The environmental loads E _PR , E _PD , E _RJ , and use environmental loads E _US of each stage are converted into CO ₂ emissions so that the impact on the global environment can be evaluated quantitatively and objectively.

Among the environmental loads described above, for the manufacturing environmental load E _PR , the distribution environmental load E _PD , and the disposal environmental load E _RJ , a standard CO2 emission amount is initially set by the manufacturer as an initial value for each manufacturing lot including the camera body 10b. The initial values of these environmental loads E _PR , E _PD and E _RJ are stored in the environmental load table 150, respectively. Instead of always storing the environmental load table 150 in the memory 157, it may be input from an external resource such as the personal computer 1 through the external I / F 161 when necessary.

Hereinafter, a method for calculating the production environmental load E _PR , the distribution environmental load E _PD , the use environmental load E _US , and the disposal environmental load E _RJ will be described.

(Method of calculating the environmental impact of manufacturing)
The manufacturing environmental load E _PR of the camera body 10b is the environmental load (material environmental load) required to manufacture the materials forming the digital camera 10 and to process these materials into parts by processing. These components are roughly classified into environmental loads (line environmental loads) required for completing the camera body 10b by assembling these components, and are calculated by adding them together.

  Here, the material environmental load is calculated as shown in the following (Table 1) using the mass, material unit, processing unit, and assembly unit for all parts constituting the product (camera body 10b). .

  The line environmental load is calculated as shown in the following (Table 2) using the basic units of the energy used and the energy discharged in the production line for manufacturing the camera body 10b.

In addition, the material environmental load and the line environmental load may vary in energy consumption, basic unit, etc. for each manufacturing lot if the manufacturing factory is different or the manufacturing lot that is the basic manufacturing unit in the manufacturing factory is different. There are cases where the production environmental impact _EPR is also different.

(Distribution environmental load calculation method)
The distribution environmental load E _PD of the camera body 10b is the following (1) when a product with a weight W (t) (digital camera 10) and ancillary materials such as packing materials are transported from a manufacturer's manufacturing factory to a destination. ) And (2).
Logistics load = transport distance x W / number of products loaded (1)
Logistics environmental load = Logistics load x Logistics basic unit (2)
Here, the transport distance is essentially the distance from the manufacturing factory to the destination (a location such as a distribution center for shipping the digital camera 10 to a retail store, a large-scale retail store warehouse, a wholesaler warehouse location). . In the case of the digital camera 10 according to the present embodiment, the average from the manufacturer's manufacturing plant to the shipping destination of the camera body 10b according to the shipping destination of the camera body 10b (domestic distribution base, export country logistics base, etc.). The initial distance is stored in advance in the memory 157 as an initial value.

(Calculation method of environmental load in use)
The use environmental load E _US of the camera body 10b is calculated as shown in the following (Table 3) based on the amount of power consumed with the use of the camera body 10b.

In addition, the environmental load E _US is the environmental load required for manufacturing the replacement part (part replacement environmental load) and the manufacture of the optional product when any part of the camera body 10b is replaced or an optional product is added. The environmental load required for (optional product replacement environmental load) is added. The replacement parts include a consumable part such as a battery that is a kind of the power supply 30, and a repair part when the camera body 10b is replaced due to a failure. The value of the environmental load for each replacement part and optional product can be stored in the memory 157 for each replacement part and optional product. However, the storage of the environmental load of the parts is not essential and can be taken in from the personal computer 1.

(Disposal environmental load calculation method)
The disposal environmental load E _RJ of the camera body 10b varies depending on the disposal method of the camera body 10b, and is calculated as shown in Table 4 below.

When the user discards the camera body 10b, not only the disposal method set in advance but also the user can change any of the disposal methods shown in (Table 4) for the camera body 10b. By changing the disposal method, the CPU 130 rewrites the disposal environmental load E _RJ set in the environmental load table 150 of the memory 157 to a value corresponding to the disposal method.

  The basic units used in Tables 1 to 4 can be updated at any time. The update can be performed by connecting to the personal computer 1 or other electronic device via the communication unit 159 and downloading from the connected electronic device.

  FIG. 2 conceptually shows the flow of LCA calculation of the entire camera 10 according to the present invention. Similar to Patent Document 1, after the camera body 10b is prototyped, it is disassembled into components such as a housing and a PCB. Each component is further disassembled and the weight of each material is measured. The power consumption required to assemble and manufacture each component is calculated by dividing the actual values.

  Then, a list for the amount of power used for each material and power for assembly manufacturing is created for each component, and these are totaled. These lists are input to the personal computer 1 by the designer and stored in the external environmental load information DB 2.

  Next, statistical materials for converting each material and power consumption into an LCA evaluation value are searched, and the LCA value of the PC main body is calculated by manual calculation from the tabulation table while appropriately combining them.

  FIG. 3 is a flowchart of the environmental load calculation process executed by the CPU 130. A program that causes the CPU 130 to execute this processing is stored in the memory 157. The CPU 130 accepts the setting as to whether or not to execute this process from the operation switch 38, and performs the process only when the setting to execute is received, and does not execute the process when the setting not to execute is received And If the setting is made not to be performed, it is possible to avoid a delay in completing the initial operation due to the environmental load calculation process.

  In S1, the power button 25 is turned on, and in response to the start of power supply to each block by the power supply 30, the power consumption measuring unit 50 is instructed to start measuring power consumption.

  In S2, reception of configuration information including identification information (ID) on the side of the mounting lens unit 10l-cur actually mounted on the camera body 10b, its substitute (manufacturing number, etc.), specifications of the image sensor, etc. The operation of the camera 10 is initialized. The configuration information is stored in a memory built in the mounting lens unit 10l-cur, which is read out by a CPU built in the mounting lens unit 10l, and is read out via the external I / F 161. To 10b. Alternatively, the IC tag or QR code attached to the mounted lens unit 101 may be read by a dedicated reading unit such as an IC tag reader or QR code reader, and the read information may be input via the external I / F 161.

  In S <b> 3, it is determined whether or not a setting for turning on display of environmental loads and other outputs is input in advance from the operation switch 38 and stored in the nonvolatile memory 157. In the case of Yes, it progresses to S4, and in No, an initialization operation | movement is complete | finished.

  In S4, the configuration information config_cur of the mounted lens unit 10l-cur received in S2 and the non-mounted lens unit that is stored in advance in the non-volatile memory 157 and is not currently mounted but received before the current power-on. The configuration information config_pre of 10l_pre is compared, and it is determined whether or not the mounted lens unit 101 is replaced from the non-mounted lens unit 10l_pre before and after the power is turned on according to whether or not the two match. If the configuration information can be received for parts other than the mounted lens unit 101, the same determination is made. Hereinafter, for the sake of brevity of description, the part is assumed to be the lens unit 101, but the same processing is possible for other parts.

  In S5, a request is made to the personal computer 1 connected via the external I / F 161 to transmit the environmental load information of the replaced mounted lens unit 10l-cur. The request includes the ID of the replaced lens unit 10l. Upon receiving the request, the personal computer 1 extracts the environmental load information corresponding to the ID included therein from the external environmental load information DB 2 and sends it back to the camera 10. Upon receiving the environmental load information, the camera 10 stores the information in the nonvolatile memory 157 in association with the ID of the mounted lens unit 10l-cur.

  When the personal computer 1 cannot extract the environmental load information corresponding to the ID included therein from the external environmental load information DB 2, it returns a notification that there is no corresponding data to the camera 10. When the camera 10 receives a notification that there is no corresponding data, it requests the personal computer 1 to search for environmental load information corresponding to the ID of the mounted lens unit 10l-cur exchanged from a resource other than the external environmental load information DB2. Also good. The search method is arbitrary. For example, the personal computer 1 is connected to a search engine (not shown), and "searches the site for the environmental load information corresponding to the ID of the attached lens unit 10l-cur" as a search keyword. The personal computer 1 connects to the searched site, acquires environmental load information, and transmits it to the camera 10. If the search is also impossible, a site for environmental load information of parts with similar specifications may be searched and transmitted to the camera 10.

  In S6, based on the received environmental load information, the environmental load during use of the camera 10 after the previous environmental load display is recalculated.

  In S7, the environmental load obtained as a result of the recalculation is displayed on the LCD 22. The display time is a short time that does not interfere with the use of the camera 10, for example, about 3 to 10 seconds. However, instead of displaying the environmental load or together with the display, the environmental load may be output to the memory card 142 and stored, or transmitted to the personal computer 1 or a printer (not shown) via the external I / F 161 for storage.

  FIG. 4 is a display example of the environmental load displayed on the LCD 22. As shown in FIG. 4A, the total environmental load may be displayed, or as shown in FIG. 4B, the environmental load may be displayed in each stage of manufacturing, transportation, use, and disposal. . The environmental load at the time of disposal is an expected value, so it is marked with *.

  For example, it is assumed that there are three types of lens units 10l that can be attached to the camera body 10b: type A, type B, and type C (hereinafter, represented by lens units 10l-A, 10l-B, and 10l-C, respectively). Table 5 lists how the environmental load information is grasped.

  The type A lens unit 10l-A is provided with environmental load information storage means such as a built-in memory and an IC tag (not shown), and ID and environmental load information (manufacturing environmental load, distribution environmental load up to the retail store, shutter) A button (a kind of operation switch 38) stores a use environmental load and a discard environmental load indicating power consumption per one press. When the lens unit 10l-A becomes the mounted lens unit 10l-cur, the CPU 130 reads out the information via the external I / F 161 or with an IC tag reader (reading unit) (not shown), and stores the environmental load table in the memory 157. Store as 150.

  However, the type A lens unit 10l-A does not have to store the physical environmental load information up to the retail store in the environmental load information. When the CPU 130 determines that the environmental load information input from the lens unit 10l-A does not include the distribution environmental load information up to the retail store, the CPU 130 specifies the location information of the lens unit 10l-A from the operation switch 38. Accept input of possible information (e.g. store address, store name). Then, the CPU 130 requests the personal computer 1 to transmit physical distribution environmental load information with the ID and the purchase address that has been input. The personal computer 1 retrieves the physical distribution environmental load information from the external environmental load information DB 2 using the ID and the location information of the acquisition source as a key, and transmits the retrieved physical distribution environmental load information to the camera body 10b. In the external environmental load information DB2, it is assumed that physical distribution environmental load information for each location information of the acquisition destination is stored in advance. The camera body 10b captures and stores the received physical distribution environmental load information in a part of the environmental load table 150. In this way, it is possible to calculate the exact environmental load at the physical distribution stage according to the source. As for the environmental load information of stages other than logistics, if the camera body 10b can input the ID from the lens unit 10l-A, it requests the personal computer 1 to transmit the environmental load information using this as a key, and the personal computer 1 The environmental load information of the stage retrieved / transmitted at can be captured and stored in a part of the environmental load table 150.

  The type B lens unit 101-B includes environmental load information storage means such as a built-in memory and an IC tag (not shown), and stores an ID. When the lens unit 10l-B becomes the mounted lens unit 10l-cur, the CPU 130 reads out the information via the external I / F 161 or an IC tag reader (reading unit) (not shown) and stores it in the memory 157.

  As described above, the CPU 130 requests the personal computer 1 to transmit the environmental load information of each stage with the ID and the purchase address inputted. The personal computer 1 retrieves the environmental load information of each stage from the external environmental load information DB 2 using the ID as a key, and transmits the retrieved physical distribution environmental load information to the camera body 10b. The camera body 10 b stores the environmental load information of each stage searched and transmitted by the personal computer 1 as an environmental load table 150.

  The type C lens unit 10l-C includes environmental load information storage means such as a built-in memory and an IC tag (not shown), and stores an ID. When the lens unit 10l-C becomes the mounted lens unit 10l-cur, the CPU 130 of the camera body 10b requests the personal computer 1 to transmit the environmental load information of each stage with the ID and the purchase address inputted. Send a notification. If the search on the external environmental load information DB2 or other Internet site using the ID as a key on the PC 1 is unsuccessful, the specifications corresponding to the ID on the Internet site (mass, price, focus) Search for distance, rated current, etc.). When the specification corresponding to the ID is found as a result of the search, the personal computer 1 transmits the specification to the camera body 10b.

  When the CPU 130 of the camera body 10b receives the specifications from the personal computer 1, the lens unit 101 (for example, the basic data such as the mass MC, the price PC, the focal length FC, etc. included in the specifications and the environmental load table 150 is stored. The apportioning ratio R is calculated from the basic data such as the mass MX, the price PX, and the focal length FX corresponding to the ID of the reference lens unit which is the lens unit 10l arbitrarily selected from type A and type B). . For example, the CPU 130 sets R = MC / MX. Alternatively, R = PC / PX. Alternatively, R = FC / FX. The CPU 130 calculates a value obtained by multiplying the environmental load value of each stage in the environmental load table 150 of the reference lens unit by the ratio R as the environmental load value of each stage of the lens unit 10l-C that is the mounted lens unit 10l-cur. These values are stored as the environmental load table 150.

  That is, as shown in FIG. 5, the unknown environmental load value of each stage of the lens unit 101-C is obtained by proportional distribution (proportional distribution) of the known environmental load values of the lens unit 101. In FIG. 5, the proportional distribution is based on the mass, but other basic data may be used.

  If even the basic data of the specifications is unknown, it is mounted with the total power consumption of the camera body 10b and the mounted lens unit 10l-cur measured by the power consumption measuring unit 50 and the environmental load value of the known lens unit 10l. The environmental load value of the lens unit 10l-cur is estimated.

  FIG. 6 is a flowchart of the environmental load value estimation process executed by the CPU 130. A program for causing the CPU 130 to execute this processing is stored in the nonvolatile memory 157. The CPU 130 accepts the setting as to whether or not to execute this process from the operation switch 38, and performs the process only when the setting to execute is received, and does not execute the process when the setting not to execute is received And

  In S11, the ID of the mounted lens unit 10l-cur is input via an external I / F 161 or an IC tag reader. However, it is assumed that environmental load information is not input from the mounted lens unit 10l-cur to the camera body 10b.

  In S12, the personal computer 1 is inquired as to whether or not the retrieval of the environmental load information of the mounted lens unit 10l-cur by the personal computer 1 is successful, and whether or not the environmental load information can be received is determined based on the content of the response to the inquiry. If the response from the personal computer 1 is “With environmental load information” (Yes), the process proceeds to S17, and if “No environmental load information” (No), the process proceeds to S13.

  In S13, specifications such as the mass, material, and rated current of the mounted lens unit 10l-cur are input via an external I / F 161, an IC tag reader, or the like.

  In S14, the personal computer 1 is requested via the external I / F 161 to search for environmental load information corresponding to the input specifications. The personal computer 1 searches the environmental load information corresponding to the specifications in response to receiving the request. For example, the personal computer 1 connects to a search engine (not shown), designates “environmental load information corresponding to specifications” as a search keyword, requests the search engine to search for a site, and if there is a searched site, The personal computer 1 connects to acquire environmental load information and transmits it to the camera 10. If the environmental load information corresponding to the specifications is transmitted from the personal computer 1 to the camera body 10b, the process proceeds to S16, and if the environmental load information is not transmitted, the process proceeds to S15.

  In S15, as described above, when the specifications are received from the personal computer 1, basic data such as the mass MC, price PC, and focal length FC included in the specifications and the lens unit 10l (environmental load table 150 stored therein) For example, the ratio R is calculated from the basic data such as the mass MX, the price PX, and the focal length FX corresponding to the ID of the reference lens unit that is the lens unit 10l arbitrarily selected from the type A and type B). . For example, since it can be considered that the mass of the motor (driving means 152) is proportional to the power consumption, this can be used as an estimation reference for environmental load information. Then, a value obtained by multiplying the environmental load value of each stage in the environmental load table 150 of the reference lens unit by the ratio R is calculated as the environmental load value of each stage of the lens unit 10l-C which is the mounted lens unit 10l-cur. These values are stored as the environmental load table 150.

  In S <b> 16, environmental load information corresponding to the specifications is received from the personal computer 1 via the external I / F 161.

  In S <b> 17, the environmental load information corresponding to the ID is received from the personal computer 1 via the external I / F 161.

  In S <b> 18, the power consumption measuring unit 50 measures the power consumption, and stores the measured power consumption in the memory 157 as environmental load information at the use stage of the camera 10. Alternatively, if the rated currents of the mounted lens unit 10l-cur and the main body 10b are stored in the memory 157, (the rated current of the mounted lens unit 10l-cur + the rated current of the main body 10b) × the total time elapsed since the power was turned on. May be the power consumption of the entire camera 10.

  In S19, environmental load information is displayed on the LCD 22. FIG. 7 shows an example of environmental load information displayed on the LCD 22 in S19. The accuracy of the environmental load information according to the information (environmental load information corresponding to the ID, environmental load information corresponding to the specifications) that is the basis of the environmental load information may be displayed together.

  Instead of the power consumption measuring unit 50, a current consumption model indicating the transition of power consumption according to the operation history is stored in the nonvolatile memory 157, and the current consumption corresponding to the operation controlled by the CPU 130 is calculated from the model. You may guess. FIG. 8 shows an example of the current consumption model.
