Abstract: A phase difference AF processing unit (19) connects detection signals of phase difference detection pixels (52A) in an AF area (53), connects detection signals of phase difference detection pixels (52B) in the AF area (53), and performs a correlation operation with respect to detection signal groups after connection to generate a defocus amount when it is determined that a subject image formed in the AF area (53) includes a high frequency component. The phase difference AF processing unit (19) performs a correlation operation with respect to detection signal groups of phase difference detection pixels (52A, 52B) in each pair line in the AF area (53) to generate the defocus amount when it is determined that the subject image formed in the AF area (53) does not include a high frequency component.

Abstract: The present invention provides an imaging device and a focusing control method capable of performing reliability determination of a phase difference AF at high speed. A phase difference AF processing unit (19) performs a correlation operation with respect to detection signal groups in first pairs P1, and performs a correlation operation with respect to detection signal groups in second pairs P2.

A system control unit (11) performs a focusing control based on the defocus amount (Df1).

Abstract: A method for manufacturing a discrete power rectifier device having a VLSI multi-cell design employs a two spacer approach to defining a P/N junction profile having good breakdown voltage characteristics. The method provides highly repeatable device characteristics at reduced cost. The active channel regions of the device are also defined using the same two spacers. The method is a self-aligned process and channel dimensions and doping characteristics may be precisely controlled despite inevitable process variations in spacer formation. Only two masking steps are required, and additional spacers for defining the body region profile can be avoided, reducing processing costs.
