摘要： In an imaging device with a wide dynamic range function by combining images, focus is controlled to establish an in-focus state for each image to enlarge the dynamic range with reducing blur, thereby improving visibility. The device includes an imaging unit with a variable focal distance focus lens, an exposure controller for controlling the imaging unit's exposure to implement several shooting operations for a subject with different sensitivity, a processing unit for processing a signal outputted from the imaging unit to generate an image signal and a focus evaluation value indicating focus degree, an image combining unit for combining signals generated by the processing unit and outputting the combined signal, the processing unit generates a focus evaluation value for each outputted signal and the focus controller controls the focus lens for shooting operations of the imaging unit with mutually different sensitivity values, based on focus evaluation values respectively associated therewith.

摘要： The autofocus function included in general digital cameras and video cameras cannot set the camera to an in-focus state for a scene including a point light source depending on cases. This difficulty is removed by an image signal processing device including an area setting unit to set an area as a target area to calculate a focus evaluation value, a detection unit to judge presence or absence of a point light source in the area set as a target area, and a calculation unit to identify, by use of information obtained from the detection unit, an area in which a point light source exists and to calculate a focus evaluation value by removing the identified area from the target area. Once the detection unit detects a point light source, it conducts the operation only after a predetermined period of time.
