A camera includes an imaging element that picks up an image of an object through a taking-lens, an evaluation value calculator that calculates focus evaluation value based upon a picked-up imaging signal, a selector that selects one focusing mode from a plurality of focusing modes, a focusing device
A camera includes an imaging element that picks up an image of an object through a taking-lens, an evaluation value calculator that calculates focus evaluation value based upon a picked-up imaging signal, a selector that selects one focusing mode from a plurality of focusing modes, a focusing device that performs a focusing operation based upon the focus evaluation value and the selected focusing mode and a rebooting device that reboots the focusing operation after the focusing operation finishes, wherein further includes an evaluation value memory device that stores a plurality of focus evaluation values calculated by the evaluation value calculator in time sequence after the focusing operation finishes and a fluctuation evaluator that evaluates fluctuation in focus evaluation value stored into the evaluation value memory device, wherein, when the rebooting device reboots the focusing operation, the selector selects one focusing mode from a plurality of focusing modes.
