  FIG. 4 is a block diagram of the camera according to the present embodiment. Reference numeral 201 denotes a barrier that prevents the image pickup system from being soiled or damaged by covering the image pickup unit including the photographing lens 202. Reference numeral 202 denotes a photographing lens, 203 denotes a shutter having a diaphragm function, and 204 denotes an imaging unit including a CCD or a CMOS element that converts an optical image into an electric signal. Reference numeral 205 denotes an A / D converter that converts an analog signal into a digital signal. The A / D converter 205 is used when an analog signal output from the imaging unit 204 is converted into a digital signal, or when an analog signal output from the audio control unit 206 is converted into a digital signal. A timing generation unit 207 supplies a clock signal and a control signal to the imaging unit 204, the audio control unit 206, the A / D converter 205, and the D / A converter 208. The timing generator 207 is controlled by the memory controller 209 and the system controller 210. An image processing unit 211 performs resize processing such as predetermined pixel interpolation and reduction, and color conversion processing on data from the A / D converter 205 or data from the memory control unit 209. The image processing unit 211 performs predetermined calculation processing using the captured image data, and the system control unit 210 performs exposure control and distance measurement control based on the obtained calculation result. Thereby, AF (autofocus) processing, AE (automatic exposure) processing, and EF (flash pre-emission) processing of the TTL (through-the-lens) method are performed. The image processing unit 211 further performs predetermined calculation processing using the captured image data, and also performs TTL AWB (auto white balance) processing based on the obtained calculation result.

  Output data from the A / D converter 205 is written into the memory 212 via the image processing unit 211 and the memory control unit 209 or directly via the memory control unit 209. The memory 212 stores image data obtained by the imaging unit 204 and converted into digital data by the A / D converter 205 and image data to be displayed on the image display unit 94 including the liquid crystal panel 81. The memory 212 is also used to store audio data recorded by the microphone 93, a still image, a moving image, and a file header when configuring an image file. Therefore, the memory 212 has a storage capacity sufficient to store a predetermined number of still images, a moving image and sound for a predetermined time.

  The compression / decompression unit 213 compresses and decompresses image data by adaptive discrete cosine transform (ADCT) or the like.

Further, the compressed image read into the memory 212 from the recording medium 301 or the like is expanded, and the processed data is written into the memory 212. The image data written to the memory 212 by the compression / decompression unit 213 is filed in the file unit of the system control unit 210. The data is recorded on the recording medium 301 through the interface 214, the connector 215, the connector 303 on the recording medium 301 side, and the interface 302. The memory 212 also serves as an image display memory (video memory). The D / A converter 208 converts the image display data stored in the memory 212 into an analog signal and supplies the analog signal to the image display unit 94. An image display unit 94 converts the display image data written in the memory 212 into an analog signal via the D / A converter 208 on the display such as the liquid crystal panel 81 and displays the image. Reference numeral 93 denotes a microphone, and an audio signal output from the microphone 93 is supplied to an A / D converter 205 via an audio control unit 206 configured by an amplifier or the like, and is converted into a digital signal by the A / D converter 205. Is stored in the memory 212 by the memory control unit 209. On the other hand, the audio data recorded on the recording medium 301 is read into the memory 212 and then converted into an analog signal by the D / A converter 208. The voice control unit 206 drives the speaker 71 with this analog signal and outputs a voice. The nonvolatile memory 216 is an electrically erasable / recordable memory, and for example, an EEPROM or the like is used. The nonvolatile memory 216 stores operation constants, programs, and the like for the system control unit 210. Here, the program is a program for executing various flowcharts described later in the present embodiment. Reference numeral 210 denotes a system control unit that implements each process of the present embodiment to be described later by executing a program recorded in the nonvolatile memory 216. A system memory 217 uses a RAM. In the system memory 217, constants and variables for operation of the system control unit 210, programs read from the nonvolatile memory 216, and the like are expanded.

  The zoom lever 107, the switching lever 102, the release button 108 and the operation unit 200 are operation means for inputting various operation instructions to the system control unit 210. The switching lever 102 can switch the operation mode of the system control unit 210 to any one of a still image recording mode, a moving image recording mode, a reproduction mode, and the like. The release button 108 includes a first release button 108a and a second release button 108b. The first release button 108a is turned on while the release button 108 is being operated (half-pressed) and generates a first shutter switch signal SW1. The system control unit 210 starts operations such as AF (autofocus) processing, AE (automatic exposure) processing, AWB (auto white balance) processing, and EF (flash pre-emission) processing in response to the first shutter switch signal SW1. . The second release button 108b is turned on when the operation of the release button 108 is completed (fully pressed) and generates a second shutter switch signal SW2. In response to the second shutter switch signal SW2, the system control unit 210 starts a series of shooting processing operations from reading a signal from the imaging unit 204 to writing image data on the recording medium 301.

  Each operation member of the operation unit 200 is appropriately assigned a function for each scene by selecting and operating various function icons displayed on the image display unit 94, and functions as various function buttons. Examples of the function buttons include an end button, a return button, an image advance button, a jump button, a narrowing button, and an attribute change button. For example, when the menu button is pressed, a menu screen on which various settings can be made is displayed on the image display unit 94. The operation unit 200 includes a cross button 121 and a center button 123. The operator makes various settings intuitively using the menu screen displayed on the image display unit 94 and the cross button 121 and the center button 123. be able to. The power button 109 switches between power on and power off.

  Reference numeral 218 denotes a power control unit, which includes a battery detection circuit, a DC-DC converter, a switch circuit that switches a block to be energized, and the like, and detects whether or not a battery is installed, the type of battery, and the remaining battery level. Further, the power control unit 218 controls the DC-DC converter based on the detection result and an instruction from the system control unit 210, and supplies a necessary voltage to each unit including the recording medium 301 for a necessary period.

  Reference numeral 219 denotes a power supply unit, which includes a primary battery such as an alkaline battery or a lithium battery, a secondary battery such as a NiCd battery, a NiMH battery, or a Li battery, an AC adapter, and the like, and corresponds to the battery 23 shown in FIGS. . A connector 32 connects the power supply unit 219 and the power supply control unit 218.

  An RTC (Real Time Clock) 220 measures the date and time. The RTC 220 holds a power supply unit therein separately from the power supply control unit 218, and keeps counting time even when the power supply unit 219 is turned off. The system control unit 210 sets a system timer using the date and time acquired from the RTC 220 at the time of activation, and executes timer control.

  Reference numeral 214 denotes an interface with the recording medium 301. Reference numeral 215 denotes a connector for connecting the recording medium 301 and the interface 214. Reference numeral 221 denotes a recording medium attachment / detachment detection unit that detects whether the recording medium 301 is attached to the connector 215.

  The recording medium 301 is a recording medium such as a memory card or a hard disk, and corresponds to the memory card 53 shown in FIGS. The recording medium 301 includes an interface 302 and a connector 303 for connecting to the camera.

  The communication unit 222 performs various communication processes such as RS232C, USB, IEEE1394, P1284, SCSI, modem, LAN, and wireless communication. A connector (antenna in the case of wireless communication) 223 connects the camera to another device via the communication unit 222.

  Next, details of the analog switch 130a and the analog switch 130b will be described with reference to FIG. 5, FIG. 6, and FIG. In the analog switch 130a, a flexible wiring board 132a and a metal plate 131a are integrally fixed. A carbon printed part 134a is provided on the flexible wiring board 132a, and a gap is formed between the carbon printed part 134a and the metal plate 131a. The wiring exposed portion 133 on the flexible wiring board 132a is adhered to the metal plate 131a while being electrically conductive with a conductive film, thereby ensuring conduction with the wiring on the flexible wiring board. When the cross button 121 is pressed by the user's contact operation, the embossed 121a or the semi-cylindrical rib 121b provided on the cross button 121 bends the carbon printing part 134a at the pressing point. At this time, the resistance value changes as the gap between the carbon printing part 134a at the pressing point and the metal plate 131a is crushed and brought into contact. The carbon printing part 134a is provided in a shape that matches the shape of the cross button 121 as shown in FIG. 5, and the resistance value varies depending on where the cross button 121 is pressed. Can be detected.

  The pressed point corresponds to a contact position that is touched when the user operates the cross button 121.

  In addition, when the user operates the cross button 121 so that the contact position changes continuously, the resistance value also changes continuously corresponding to the continuous change of the contact position. The amount of operation for the cross button 121 is known.

  In the analog switch 130b, a flexible wiring board 132b and a metal plate 131b are fixed integrally. The flexible printed circuit board 132b is provided with a carbon printing part 134b, and a gap is formed between the carbon printing part 134b and the metal plate 131b. When the center button 123 is pressed by the user's contact operation, the emboss 123a provided on the center button 123 bends the carbon printing part 134b. At this time, the resistance value changes as the gap between the carbon printing part 134b at the pressing point and the metal plate 131b is crushed and brought into contact. It can be detected from the change in the resistance value that the center button 123 is pressed.

  The gap between the carbon printing part 134a and the metal plate 131a and the gap between the carbon printing part 134b and the metal plate 131b are very small, and the flexible wiring board 132a can be bent with a slight force. Therefore, it can be detected that the cross button 121 and the center button 123 are pressed only by touching the user.

  However, if the menu corresponding to each button can be determined simply by touching the cross button 121 and the center button 123, the menu is determined only by touching the user unintentionally. Therefore, when performing menu determination corresponding to each of the cross button 121 and the center button 123, a force that is enough to press the metal dome sheet 141 is required, and the menu is not determined only by touching the user.

  Further, when the analog switch 130a is configured only on the cross button 121 as in the prior art, the user's finger touches the cross button 121 when pressing the center button 123 as shown in FIG. An unintended menu was sometimes determined. In order to prevent such an erroneous operation, the analog switch 130b is provided on the center button 123 as described above, and it is determined by the user's operation whether the operation of the cross button 121 is enabled or the operation of the center button 123 is enabled. The control is performed.

  Next, control when the user operates the cross button 121 will be described with reference to the flowchart of FIG.

  In the camera of the present embodiment, the system control unit 210 performs processing of operations performed on the cross button 121 and the center button 123.

  When it is detected that the cross button 121 is touched by the user (S101), it is determined whether or not the center button 123 is touched by the user (S102). Whether or not the cross button 121 and the center button 123 are touched is detected by signals from the analog switch 130a and the analog switch 130b. Next, based on the result of S102, a predetermined amount used to determine which operation of the cross button 121 or the center button 123 is to be validated is set. In this flowchart, a case where an angle is set as a predetermined amount will be described. When the center button 123 is touched, the predetermined angle is set to 90 degrees (first predetermined amount) (S103), and when the center button 123 is not touched, the predetermined angle is set to 45 degrees (the first predetermined amount). Second predetermined amount) (S104).

  The reason why the predetermined angle to be set is changed depending on whether or not the center button 123 is touched in S103 and S104 is to facilitate the user's operation. When the cross button 121 and the center button 123 are provided adjacent to each other as shown in FIG. 3, the user may touch the cross button 121 when trying to operate the center button 123. If the operation on the cross button 121 is reflected at such time, an operation not intended by the user is performed, resulting in an erroneous operation. Therefore, the predetermined angle is set larger when the center button 123 is touched than when the center button 123 is not touched. Thereby, an erroneous operation can be prevented and an operation intended by the user can be validated. Even when the center button 123 is not touched, the predetermined angle is set so as not to cause an erroneous operation in response to a slight operation amount when the menu is determined by the cross button 121. However, the predetermined angle at this time is set smaller than when the center button 123 is touched so as not to prevent the operation of the cross button 121.

  Next, the operation amount of the cross button 121 is calculated from the change in the position touched by the cross button 121 (S105). The operation amount of the cross button 121 is an amount indicating how much the position touched by the cross button 121 has changed since the start of the operation by the user's operation, and is obtained from the change amount of the resistance value of the analog switch 130a. . In this flowchart, the angle between the center of the cross button 121 and the position touched at the start of the operation is used as the operation amount.

  Next, it is determined whether or not the operation amount of the cross button 121 is equal to or larger than the predetermined angle set in S103 or S104 (S106). When the operation amount of the cross button 121 is equal to or larger than the predetermined angle, it is assumed that the user intends to operate the cross button 121, and the operation of the cross button 121 is validated (S107). If the angle is less than the predetermined angle, it is assumed that the user intends to operate the center button 123, and the operation of the center button 123 is validated (S108).

  As described above, by changing the predetermined angle for determining whether the user intends to operate the cross button 121 based on whether or not the center button 123 is touched by the user, an erroneous operation can be prevented, and The operation desired by the user can be validated.

  In this embodiment, the predetermined angle is 90 degrees when the center button 123 is touched and 45 degrees when the center button 123 is not touched. However, the predetermined angle is not limited to this angle, and a desired effect is obtained. If obtained, the angle is not limited.

  Further, the operation amount of the operation on the cross button 121 is obtained as an angle change amount to prevent an erroneous operation. However, the operation amount is not limited to the angle, and other operation amounts, for example, changes in the operation moving speed, the operation moving distance, and the like are detected. You may prevent incorrect operation. In such a case, a predetermined amount corresponding to each operation amount is set in S103 and S104, and the button to be activated is changed depending on whether the operation amount for the cross button 121 is equal to or larger than the predetermined amount or less than the predetermined amount. It may be controlled to.

  Further, although the configuration using the analog switch 130a and the switch of the metal dome sheet 141 in which the resistance value continuously changes depending on the pressing point of the cross button 121 has been described, the configuration is not limited to such a configuration. For example, application is easy even when other switches such as a pressure-sensitive switch for detecting the pressed pressure, a switch for detecting a change in capacitance by detecting static electricity, and a tact switch are used.

  Further, although the metal dome sheet 141 is disposed so as to overlap in the pushing direction of the cross button 121, it is not always necessary.

  The shape of the cross button 121 is not limited to a ring shape, and may be any shape that allows the selection operation to be performed by moving the pressing point.

  Further, the cross button 121 may be configured by a plurality of operation members and arranged so as to surround the center button 123.

  Moreover, although the cross button 121 and the center button 123 are formed of separate members, they may be formed of the same member.
