摘要： A charge transfer device includes a circuit which can correct a fluctuated amount of light (charge amount)--output voltage characteristic with accuracy even when fluctuated by the change of temperature and the fluctuation of a power supply voltage. An output voltage characteristic in the standard state corresponding to a reference charge is stored and held in a ROM in advance. An ALU (arithmetic logical unit) corrects the light (charge amount)--output voltage characteristic by using the output voltage characteristic in the standard state corresponding to the reference charge stored in the ROM and the output voltages corresponding to the reference charge inputs from reference charge input portions in an imaging state, and corrects an output voltage (Va) corresponding to a signal charge in a practical imaging state.

摘要： A camera having a subject tracking function automatically tracks a subject that moves within a subject field. The camera immediately changes the subject to be tracked without changing a frame. The camera is configured by providing a light measurement unit which measures light by dividing the subject field into multiple regions and outputs multiple light measurement data relating to the brightness of the subject field. A subject tracking unit tracks the subject by detecting the movement of the subject using the output from the light measurement unit, and a focal point detecting unit that includes multiple focal point detection regions within the subject field and detects the status of the focal point adjustment unit if the focal point of a photographic lens is manually adjusted. If the focal point of the photographic lens is adjusted by the subject tracking unit, and at least one of the multiple focal point detection regions is in focus, the subject tracking unit tracks the subject position in the focal point detection region that is in focus as the new subject.

A first judgment device judges, whether the object in each area is colored or uncolored based on the light metering signal, and determines colored areas in which the object is colored and uncolored areas in which the object is uncolored. A second judgment device judges whether a predetermined uncolored area contains a white or black object, based on the light metering signals from the colored areas and those from the uncolored areas. An exposure value determining device determines the exposure value according to the light metering signals, based on the results of judgment by the first and second judgment devices.
