Description

  The present invention relates to a camera sequence that can be set in a plurality of shooting setting states.

  FIG. 3 shows a block diagram of a general camera. In FIG. 3, 1 is a sequence controller for controlling the entire camera, 2 is a mode setting member such as a dial or button for setting various modes such as a photographing mode, a photometry mode, and an autofocus mode. A display panel such as an LCD panel for displaying a set mode, the number of frames to be photographed, etc., 4 is a known photometry circuit including a photometry sensor for measuring subject brightness, 5 is a photographing lens, and 6 is for autofocusing. A known autofocus circuit, 7 is a film exposure device such as a shutter, 8 is a film feeding device, 9 is a release SW for starting a series of release operations such as photometry and autofocus operation and film exposure, and 10 is a camera. A battery that supplies power to the whole.

FIG. 4 is a flowchart showing a series of operations & photographing sequences by the camera. In FIG. 4, it is first checked whether or not a mode change operation has been performed by the mode setting member 2 (# 501). If a mode change operation has been performed, the mode is changed according to the operation (# 502) and the initial state is restored. For example, when the metering mode is switched from average metering to spot metering, the spot metering is set. If the mode change operation is not performed in # 501, it is next checked whether or not the release SW9 is turned on (# 503). If it is not turned on, it returns to the initial state, and if it is turned on, a series corresponding to the set mode is checked. Release operation (photometry, autofocus, film exposure, film feeding) is performed (# 504), and the release SW is turned off (# 505) to return to the initial state.

  In the above conventional example, the photographer sets the mode by the mode setting member 2 for each release and performs the release operation. However, there are times when the photographer wants to return to the setting of the previous frame when attempting to release. In such a case, the photographer's memory is re-set to the previous state, but in some cases it may not be remembered. It will be difficult to remember, especially if you changed the mode after the previous release and it has been a long time since.

  The present invention has been made paying attention to the above points, and it is an object of the present invention to provide a camera aimed at improving operability when it is desired to return to the setting of the previous frame.

  According to the present invention, the above problem is solved by providing the camera with a so-called UNDO function that automatically returns the mode to the setting of the previous shooting frame. It also has a so-called REDO function that resets to the setting state before the UNDO function execution operation. Furthermore, when the UNDO function cannot be executed due to circumstances, a warning is issued, or the state closest to the shooting setting state one frame before By automatically setting the camera, it is possible to provide a camera that is easier for the photographer to use.

  That is, the technical contents of the present invention can solve the above-described problems by including the following configuration.

  (1) For one or a plurality of setting modes that can be set by the photographer, a so-called UNDO function that automatically returns to the previous setting state is provided, and an operation for executing the UNDO function is performed, thereby taking a picture one frame before. A camera that is automatically set to the hour setting state.

  (2) The camera according to (1), further comprising a so-called REDO function for resetting to a set state before the UNDO function execution operation after the UNDO function execution operation.

  (3) The camera according to (1), wherein a warning is issued when the UNDO function execution operation cannot be set to the shooting setting state one frame before.

  (4) In the above (1), when the UNDO function execution operation cannot be set to the shooting setting state one frame before, it is automatically set to the state closest to the shooting setting state one frame before. Camera characterized by.

  According to the present invention, by providing the camera with a so-called UNDO function that automatically returns the mode to the setting of the previous shooting frame, it is possible to save the trouble of resetting to the previous state depending on the memory of the photographer. In addition, a setting with no memory error is possible. It also has a so-called REDO function that resets to the setting state before the UNDO function execution operation. Furthermore, when the UNDO function cannot be executed due to circumstances, a warning is issued, or the state closest to the shooting setting state one frame before By automatically setting the camera, it is possible to provide a camera that is easier for the photographer to use.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to examples.

  A block diagram showing an embodiment of the present invention is shown in FIG. In the block diagram of FIG. 1, 1 to 10 are the same as 1 to 10 in FIG.

  In FIG. 1, 11 is an EEPROM as a non-volatile memory for storing modes as needed in the camera, and 12 is for executing a so-called UNDO function for automatically returning the setting mode to the setting of the previous shooting frame. The UNDO switch 13 is a REDO switch for executing a so-called REDO function for resetting to a set state before the UNDO function execution operation. The operation sequence using this block diagram will be described with reference to the flowchart of FIG. In FIG. 2, mode A means the currently set setting mode, and mode B means the previous shooting frame setting mode.

  In FIG. 2, it is first checked whether or not a mode changing operation has been performed by the mode setting member 2 (# 101). If a mode changing operation has been performed, the mode is changed according to the operation (# 102). And stored in the camera (# 103) to return to the initial state. For example, when the metering mode is switched from the average metering to the spot metering, the spot metering is set, and the mode A is set to “spot metering”. If the mode change operation is not performed in # 101, it is checked whether the UNDO switch 12 is turned on next (# 104). If it is ON, the mode B is set as the setting mode for the next previous frame. It is determined whether or not it is possible (# 110). For example, when the photometry mode cannot be taken by spot photometry due to the convenience of the taking lens, a warning operation is performed by sounding an alarm sound or displaying a warning display assuming that mode B cannot be set (# 113). If it is possible to set the mode B, which is the setting mode for the previous frame at # 110, the mode B is set as the setting mode (# 111), the UNDO switch is turned off (# 112), and the initial state is restored. If the UNDO switch is OFF in # 104, it is next checked whether the REDO switch is ON (# 105). If the REDO switch is ON in # 105, the setting mode is returned to mode A in order to reset to the setting state before the UNDO function execution operation (# 114), and waiting for the REDO switch to be turned OFF (# 115). Return to the initial state. If the REDO switch is OFF in # 105, it is next checked whether the release SW9 is ON (# 106). If it is OFF, it returns to the initial state, and if it is ON, it corresponds to the set mode. Performs a series of release operations (photometry, autofocus, film exposure, film feeding) (# 107), stores the setting mode at that time as mode B (# 108), and waits for the release SW to be turned off (# 109) Return to the initial state.

  The above embodiment only supports until the UNDO function returns to the previous shooting frame state. However, by storing the shooting mode of a plurality of past frames, the UNDO switch can be continuously pressed. It is also possible to return to the mode at the time of the previous shooting frame.

  In addition, a warning is issued when the UNDO function cannot be executed due to circumstances, but even if it cannot be executed as it is, it is automatically set to a state closest to the setting state at the time of shooting one frame before. You can also. For example, if the metering mode has three modes of spot metering, partial metering, and average metering, and the previous frame was shot with spot metering and shooting with spot metering is not possible due to the current shooting lens, it is not spot metering. In both cases, photographing is performed with partial metering, which is a mode close to spot metering.

  As explained above, by giving the camera a so-called UNDO function that automatically returns the mode to the setting of the previous shooting frame, it is possible to save the trouble of resetting to the previous state depending on the memory of the photographer, In addition, setting without memory mistakes became possible. It also has a so-called REDO function that resets to the setting state before the UNDO function execution operation. Furthermore, when the UNDO function cannot be executed due to circumstances, a warning is issued, or the state closest to the shooting setting state one frame before By automatically setting the camera to a camera, it provided a camera that was easier for photographers to use.
