Title:
ELECTRONIC CAMERA
Document Type and Number:
Japanese Patent JP2009124313
Kind Code:
A
Abstract:

To provide an electronic camera capable of appropriately storing distribution information on de-focus information in a photography screen.

The electronic camera comprises a focus detection means 4c, an image sensor 3, and a recording control means 4. The focus detection means 4c divides an object luminous flux passed into a photo-optical system 1 into two lines, and detects de-focus information based on phase difference between two images formed by the two luminous fluxes, respectively. The optical system for dividing the object luminous flux into two lines is formed substantially throughout the imaging face of the image sensor 3. The recording control means 4 records information indicative of the distribution of the de-focus information at the imaging face detected by the focus detection means 4c onto a record medium 9.
