Patent ID: 7283736

Claim:
An imaging apparatus, comprising: a photographic operating device including at least two-step operational positions having a half-pressed position and a full-pressed position; a ranging device to measure a distance to a subject; a fill-light radiating device to radiate fill light to the subject; a fill-light determining device to determine whether the fill light is required; a re-ranging determining device to determine whether a re-ranging is required to be executed based on a measured result of the ranging device; and a processor connecting to the photographic operating device, the ranging device, the fill-light radiating device, the fill-light determining device, and the re-ranging determining device, wherein when the photographic operating device is in the half-pressed position, in case that the re-ranging determining device determines that the re-ranging is required and the fill-light determining device determines that the fill light is required, the processor controls to allow the photographic operating device to wait for being in the full-pressed position, and controls the fill-light radiating device to radiate the fill-light, and the ranging device to perform the re-ranging when the photographic operating device is in the full-pressed position.
