Camera display device with reduced display time

A camera display device, comprising:

• a switch having an ON position and an OFF position;
• a measuring device to measure photographic data when the switch is in the ON position;
• a display, including an indicating needle and a display scale, to display photographic data measured by the measuring device according to a position pointed to by the indicating needle on the display scale;
• a timer to time a predetermined period of time, starting when the switch switches from the ON position to the OFF position and ending when the timer times out;
• a hold command unit, operating when the switch switches from the ON position to the OFF position, to control the indicating needle to hold at a first display position for the predetermined period of time, and to control the indicating needle to return to an origin position after the predetermined period of time;
• and
• an update command unit, to control the indicating needle to move directly from the first display position to a second display position when the switch is switched ON during the hold period and a new measurement of photographic data is performed.

A display device comprising:

• a measuring device to measure data;
• a display including an indicating needle and a display scale, the indicating needle pointing to the display scale to display data measured by the measuring device;
• and
• a control unit, operatively coupled to the measuring device and to the display, to control the indicating needle to display first measured data in response to a first measurement of data by the measuring device, to hold the indicating needle at a position displaying the first measured data for a predetermined period of time and to control the indicating needle to move directly from the position displaying the first measured data to a position displaying second measured data in response to a second measurement of data by the measuring device when the indicating needle is at the position displaying the first measured data.

A method for controlling a display of data on a display having an indicating needle pointing to positions on a display scale to display data, comprising:

• measuring first data and moving the indicating needle to a first display position displaying the measured first data;
• holding the indicating needle at the first display position for a predetermined period of time;
• measuring second data;
• and
• moving the indicating needle directly from the first display position to a second display position displaying the measured second data when the step of measuring second data occurs during the predetermined period of time during which the indicating needle is held at the first display position.
