Disclosed herein are systems and methods for accurately detecting button presses and/or button releases on a keypad of a camera such as an endoscopic camera head. A button press and/or a button release may be detected by determining a change in the sensor voltage output from a magnetic field sensor and identifying a spike in the sensor voltage change. A spike occurs when the slope of the sensor voltage has a magnitude that is greater than a slope threshold, and indicates a button press and/or a button release. Aspects of the disclosure comprise a controller that identifies a spike. The controller may identify a second spike and determine the type of button press based on the duration between the first spike and the second spike. The disclosed systems and methods may further include and apply to a keypad comprising a plurality of buttons, such as closely-spaced buttons and concentric buttons.
