Description

  The present invention relates to a silver salt camera, a digital camera, and a portable information input device.

  Recent digital cameras tend to be smaller, more portable, and less consumed.

  In accordance with this, the number of retractable lens barrels including the taking lens system is increasing, and the power supply system for driving the lens barrel is also lowered in voltage.

Here, in a digital camera that functions as a cover of the monitor and that is attached to the camera body so as to be freely opened and closed, and that exposes or incorporates the monitor by opening and closing the upper lid, the upper lid state detecting means detects the open and closed state of the upper lid The control means links the opening and closing of the upper lid and the power on / off control so that the power supply to the camera body and / or the monitor can be controlled based on the detection result of the upper lid state detection means, There has been proposed a technique for reducing the number of operation switches and improving operability, and providing a low power consumption digital camera without wasteful power consumption (see, for example, Patent Document 1).

  Next, the processing of the present invention will be described as a first embodiment with reference to the flowchart shown in FIG.

  First, when the power SW 13 is pressed, various initial settings are made by the CPU block (104-3) in the digital still camera processor (104) (S1).

  After the initial setting, the state of the lens barrel is determined (S2). If the lens barrel is in the retracted state, the zoom drive motor (7-1b) moves the lens barrel to the Wide position of the photographing standby position. (S3), followed by a shutter opening process (S4) and a focus reset process (S5), which is a focus lens resetting operation, and the initialization of the lens barrel unit (7) is completed.

  In the lens barrel state determination (S2), if the lens barrel state is already in the shooting standby state, the initialization process of the lens barrel unit (7) is only the shutter opening process (S6).

  Next, in the F / E activation process (S7), the power of the CCD (101) system is turned on to set the F / E-IC (102). Then, a through image is displayed on the LCD in the monitoring preparation process (S8).

  During shooting standby, AE / AWB update processing (S9) is periodically performed to provide an appropriate image.

  Next, the user determines whether or not the release shutter (SW1) is in a short-pressed state, that is, whether or not the first-stage release switch is turned on (S10). AF processing (S11), AE processing (S12), and AWB processing (S13), which are preliminary operations, are sequentially executed.

  Next, it is determined whether or not the release shutter (SW1) is in a long-pressed state, that is, whether or not the second-stage release switch is turned on in addition to the first stage (S14). If the result of this determination is that the release shutter (SW1) is in the long-pressed state, monitoring is stopped because the release instruction has been issued (S15), and the actual imaging operation, ie, the CCD (101), F / E-IC ( 102), the image pickup operation (S16) of the CCD1 signal processing block (104-1), the image processing (S17) in the CCD2 signal processing block (104-2), and JPEG compression by the JPEG CODEC block (104-7), Recording on the memory card is performed in the memory card controller block (104-10) (S18). Then, the monitoring preparation process (S8) is performed again, and the process returns to the photographing standby state (S9).

  Further, during shooting standby, the user also determines whether or not the power SW (13) has been pressed to turn off the power (S19). If the result of this determination is that it is on, it is next determined whether or not standby mode is set (S20). The standby mode is a mode in which the lens barrel is in a shooting state and the power is turned off. When the camera is next activated by the power switch (13), the initialization process of the mechanical lens barrel unit can be omitted, and the activation time can be shortened. , Leading to shortened release timing.

  If the standby mode is valid as a result of the standby mode determination, a timer is started to measure the ON time of the power switch (S21). Next, the monitoring (image display) is stopped (S22), and the F / E stop processing (S23) is performed to set the F / E stop and turn off the CCD system power. Then, a shutter closing process (S24) is performed to close the shutter, and it is determined whether or not the power switch is turned off (S25). Here, if it is detected that the power switch is turned off before 2 seconds elapses from the previous timer, the power is turned off as it is. If the power switch is still on after 2 seconds (S26), the focus lens is moved to the storage position (S27) and the lens barrel is moved to the storage position in order to place the lens barrel unit in the storage state. (S28) The power is turned off.

  If the standby mode is determined to be invalid in the standby mode determination, the lens barrel unit is placed in the retracted state (S29 to S33) regardless of the operation method of the power switch, and the power is turned off.

  Next, the processing of the present invention will be described as a second embodiment with reference to the flowchart shown in FIG.

  In the description of the second embodiment, only portions different from the first embodiment will be described.

  It is determined whether or not the power SW (13) has been pressed to turn off the power by the user's operation (S19). If the result of this determination is that it is on, then the standby mode is set. It is determined whether or not there is (S20).

  If the standby mode is valid as a result of the standby mode determination, a timer is started to measure the ON time of the power switch (S21). Next, the monitoring (image display) is stopped (S22), and the F / E stop processing (S23) is performed to set the F / E stop and turn off the CCD system power. Then, a shutter closing process (S24) is performed to close the shutter, and only when the lens barrel position is not at the Wide position, the shutter is moved to the Wide position (S25). Then, it is determined whether or not the power switch is turned off (S26). Here, if it is detected that the power switch is turned off before 2 seconds elapses from the previous timer, the power is turned off as it is. If the power switch is still on after 2 seconds (S27), the focus lens is moved to the storage position (S28) and the lens barrel is moved to the storage position in order to place the lens barrel unit in the storage state. (S29) The power is turned off.

  When the standby mode is determined to be invalid in the standby mode determination, the lens barrel unit is set in the retracted state (S30 to S34) and the power is turned off regardless of the operation method of the power switch.

  Next, the processing of the present invention will be described as a third embodiment with reference to the flowchart shown in FIG.

  First, when the power SW 13 is pressed, various initial settings are performed by the CPU block (104-3) in the digital still camera processor (104) (S1). After the initial setting, the state of the lens barrel is determined (S2). If the lens barrel is in the retracted state, the zoom drive motor (7-1b) moves the lens barrel to the Wide position of the photographing standby position. (S3), followed by a shutter opening process (S4) and a focus reset process (S5), which is a focus lens resetting operation, and the initialization of the lens barrel unit (7) is completed.

  In the lens barrel state determination (S2), if the lens barrel state is already in the shooting standby state, the initialization process of the lens barrel unit (7) is only the shutter opening process (S6).

  Next, in the F / E activation process (S7), the power of the CCD (101) system is turned on to set the F / E-IC (102). Then, a through image is displayed on the LCD in the monitoring preparation process (S8).

  During shooting standby, AE / AWB update processing (S9) is periodically performed to provide an appropriate image.

  Next, the user determines whether the release shutter (SW1) is half-pressed, that is, whether or not the first-stage release switch is turned on (S10). AF processing (S11), AE processing (S12), and AWB processing (S13), which are preliminary operations, are sequentially executed.

  Next, it is determined whether or not the release shutter (SW1) is fully pressed, that is, whether or not the second-stage release switch is turned on in addition to the first stage (S14). If the result of this determination is that the release shutter (SW1) is in the fully depressed state, monitoring is stopped as if a release instruction has been issued (S15), and the actual imaging operation, ie, CCD (101), F / E-IC ( 102), the image pickup operation (S16) of the CCD1 signal processing block (104-1), the image processing (S17) in the CCD2 signal processing block (104-2), and JPEG compression by the JPEG CODEC block (104-7), Recording on the memory card is performed in the memory card controller block (104-10) (S18). Then, the monitoring preparation process (S8) is performed again, and the process returns to the photographing standby state (S9).

  Further, during shooting standby, in order to turn off the power, the user also determines whether the power SW (13) is half-pressed, that is, whether the first-stage power switch is turned on (S19). If the result of this determination is that it is on, it is next determined whether or not standby mode is set (S20). The standby mode is a mode in which the lens barrel is in a shooting state and the power is turned off. When the camera is next activated by the power switch (13), the initialization process of the mechanical lens barrel unit can be omitted, and the activation time can be shortened. , Leading to shortened release timing.

  If the standby mode is valid as a result of the standby mode determination, the monitoring (image display) is stopped (S21), and the F / E stop processing (S22) is performed and the F / E stop setting and the CCD system power supply are turned off. To do. Then, a shutter closing process (S23) is performed to close the shutter, and it is determined whether or not the half-pressed state of the power switch is released, that is, whether or not the first-stage power switch is turned off (S24). Here, when it is detected that the first-stage power switch is turned off, the power is turned off as it is. In addition, when the power switch is half-pressed without being released, that is, when the second-stage power switch is turned on in addition to the first-stage power switch (S25), the lens barrel unit is placed in the retracted state. Therefore, the focus lens is moved to the storage position (S26), the lens barrel is moved to the storage position (S27), and the power is turned off.

  If the standby mode is determined to be invalid in the standby mode determination, the lens barrel unit is placed in the retracted state (S28 to S32) and the power is turned off regardless of the operation method of the power switch.

  Next, the processing of the present invention will be described as a fourth embodiment with reference to the flowchart shown in FIG. In the description of the second embodiment, only portions different from the first embodiment will be described.

  In order to turn off the power by the user's operation, it is also determined whether or not the power SW (13) is half-pressed, that is, whether or not the first stage power switch is turned on (S19). If the result of this determination is that it is on, it is next determined whether or not standby mode is set (S20).

  If the standby mode is valid as a result of the standby mode determination, the monitoring (image display) is stopped (S21), and the F / E stop processing (S22) is performed and the F / E stop setting and the CCD system power supply are turned off. To do. Then, a shutter closing process (S23) is performed to close the shutter, and only when the lens barrel position is not at the Wide position, the shutter is moved to the Wide position (S24). Then, it is determined whether or not the half-pressed state of the power switch is released, that is, whether or not the first stage power switch is turned off (S25). Here, when it is detected that the first-stage power switch is turned off, the power is turned off as it is. In addition, when the power switch is half-pressed without being released, that is, when the second-stage power switch is turned on in addition to the first-stage power switch (S26), the lens barrel unit is placed in the retracted state. Therefore, the focus lens is moved to the storage position (S27), the lens barrel is moved to the storage position (S28), and the power is turned off.

  If the standby mode is determined to be invalid in the standby mode determination, the lens barrel unit is placed in the retracted state (S29 to S33) regardless of the operation method of the power switch, and the power is turned off.

  According to the above embodiment, when the power switch for turning off the power is short-pressed or half-pressed, the camera enters the low-consumption mode while keeping the photographing enabled state. Shooting preparation processing can be reduced and startup time is increased.

  In addition, when the power switch for turning off the power is pressed shortly or half-pressed, the lens barrel is not retracted, and the camera enters the low power consumption mode. Therefore, the startup time is faster.

  In addition, when the power switch for turning off the power is short-pressed or half-pressed, the movement of the wide end occurs only when the lens barrel position is other than the wide end, but the low-consumption mode is entered without performing the retracting operation of the lens barrel. Therefore, at the next startup by the power switch, the startup operation of the lens barrel is unnecessary, so that the startup time is shortened.

  Also, since Tele has a larger amount of protrusion, portability is improved by setting the Wide position with a smaller amount of protrusion.

  Further, the operation of the power switch for turning on the power is shortened or half-pressed to improve operability.

  Further, in the standby mode (low consumption mode in which the lens barrel can be photographed), the convenience is improved by starting with the release switch.

  Further, by closing the shutter, the CCD is protected (CCD burn prevention).

  Further, by providing the standby mode setting, the convenience of the user can be improved.

  Further, the operability can be improved by operating the power switch when the standby mode is off as a short press or a half press.

  Each of the above-described embodiments is a preferred embodiment of the present invention, and various modifications can be made without departing from the scope of the present invention.
