Document Type and Number:
Japanese Patent JP6748847
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an imaging device for generating a focus assist signal with high accuracy that facilitates the focusing operation during a manual focus operation.SOLUTION: An imaging device includes a distance information calculation unit 5, a high frequency signal extraction unit 1, a focus assist signal generation unit 2, and a signal composing unit 3. The distance information calculation unit 5 calculates distance information of a video signal, and generates a focus range signal from current focus information and the distance information. The high frequency signal extraction unit 1 extracts a high frequency signal of the video signal. The focus assist signal generating unit 2 generates a focus assist signal representing an in-focus area by using the high frequency signal and the focus range signal. The signal composing unit 3 combines the focus assist signal with the video signal to generate a video signal with a focus assist signal.SELECTED DRAWING: Figure 2
