Shutter speed digital display device for cameras

A shutter speed digital display device for cameras having both automatic and manual shutter speed controls comprising:

• a. digital shutter speed display means for displaying shutter speed comprising:
• 1. a display control circuit connected to said automatic shutter speed control of said camera for generating an output representing the shutter speed determined by said automatic shutter speed control of said camera;
• and,
• 2. a liquid crystal display means connected to the output of said display control circuit in a manner such that a particular shutter speed digital display is created when a particular output of said display control circuit occurs;
• b. a manual shutter speed setting circuit for generating an output representing the manual setting of the shutter speed of said camera;
• c. comparator means connected to said display control circuit and to said manual shutter speed setting circuit for comparing a signal related to the digital shutter speed displayed by said liquid crystal display means with the output of said manual shutter speed setting circuit and generating an output related to whether or not there is coincidence between said shutter speed display and said output of said manual shutter speed setting circuit;
• and,
• d. a coincidence indicator connected to the output of said comparator means for indicating when said comparator means senses coincidence between said shutter speed digital display and the output of said manual shutter speed setting circuit.
