Abstract

Abstract A camera wherein the light emitted by a subject, which has passed through a photographic optical system, is formed as an image on an area sensor, and which includes an electronic viewfinder that indicates the image of the subject based on the output from the area sensor and an apparatus that detects image shaking caused by camera shake, based on the output from the area sensor.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 119 words
A camera capable of detecting relative camera shake between the camera and a subject, comprising: image sensing means for producing image data in accordance with a subject image formed on said image sensing means; dividing means for dividing an image sensing area of said image sensing means into plural parts; calculating means for calculating contrast values of the subject image in said plural parts respectively based on the image data produced by said image sensing means; selecting means for selecting at least one part among the plural parts based on the calculated contrast values; and detecting means for detecting the relative camera shake between the camera and the subject based on the image data procured from the selected part.
Claim 2
Dependent Claim 119 words
A camera capable of detecting relative camera shake between the camera and a subject, comprising: image sensing means for producing image data in accordance with a subject image formed on said image sensing means; dividing means for dividing an image sensing area of said image sensing means into plural parts; calculating means for calculating contrast values of the subject image in said plural parts respectively based on the image data produced by said image sensing means; selecting means for selecting at least one part among the plural parts based on the calculated contrast values; and detecting means for detecting the relative camera shake between the camera and the subject based on the image data procured from the selected part.
Claim 3
Dependent Claim 16 words
A camera as sated in claim 1, wherein said image sensing means is an area sensor.
Claim 4
Dependent Claim 24 words
A camera as stated in claim 1, wherein said selecting means selects at least one part in order of height of the contrast values.
Claim 5
Dependent Claim 30 words
A camera as stated in claim 1, further comprising correcting means for correcting the relative camera shake based on an amount of the camera shake detected by said detecting means.
Claim 6
Dependent Claim 143 words
A camera capable of detecting relative camera shake between the camera and a subject, comprising: image sensing means for producing image data in accordance with a subject image formed on said image sensing means; memory means for storing the image data produced by said image sensing means; detecting means for detecting the relative camera shake between the camera and the subject based on the image data produced by said image sensing means; first calculating means for calculating a contrast value in a horizontal direction based on the image data stored in said memory means; second calculating means for calculating a contrast value in a vertical direction based on the image data stored in said memory means; and controlling means for controlling the image data to be used for camera shake detection in accordance with the contrast values in the horizontal and vertical directions.
Claim 7
Dependent Claim 143 words
A camera capable of detecting relative camera shake between the camera and a subject, comprising: image sensing means for producing image data in accordance with a subject image formed on said image sensing means; memory means for storing the image data produced by said image sensing means; detecting means for detecting the relative camera shake between the camera and the subject based on the image data produced by said image sensing means; first calculating means for calculating a contrast value in a horizontal direction based on the image data stored in said memory means; second calculating means for calculating a contrast value in a vertical direction based on the image data stored in said memory means; and controlling means for controlling the image data to be used for camera shake detection in accordance with the contrast values in the horizontal and vertical directions.
Claim 8
Dependent Claim 16 words
A camera as stated in claim 5, wherein said image sensing means is an area sensor.
Claim 9
Dependent Claim 45 words
A camera as stated in claim 5, wherein said memory means includes two memory members and said first and second calculating means include means for subtracting image data stored in one of the memory members from image data stored in another of the memory members.
Claim 10
Dependent Claim 53 words
A camera as stated in claim 5, wherein said controlling means includes means for picking out a part of image sensing area of said image sensing means in accordance with the contrast values, and said detecting means detects the relative camera shake based on the image data produced from the picked out part.
