Abstract
Abstract The position of a principal image within a frame is designated manually or in association with the operation of the automatic focussing mechanism. The position information of the principal image is recorded on a photographic film when a subject is photographed. In obtaining a photoprint, the position information is read from the frame to be printed, and the principal image within the frame is identified. A characteristic value used for calculating an exposure amount is derived from the identified principal image, so as to execute an exposure control emphasizing the principal image.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
154 words
In a camera for taking a scene by performing range finding for a principal subject within a range finding area of a finder view field at a first stage of release member actuation and operating a shutter at a second stage of release member actuation; an apparatus for recording the position information of a principal image, said apparatus comprising: an image sensor for outputting a time sequential signal by taking a subject; a memory for storing said time sequential signal outputted from said image sensor at the time of range finding; means for comparing said time sequential signal stored in said memory with a time sequential signal outputted in real time from said image sensor so as to detect said position of said principal subject within said frame; and means for recording information on a recording medium, said information representative of said position of said principal subject being detected at the time of photographing.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
15 words
An apparatus according to claim 1, wherein said image sensor is a line image sensor.
Claim 4
Dependent Claim
15 words
An apparatus according to claim 1, wherein said image sensor is an image area sensor.
Claim 5
Dependent Claim
167 words
In a camera for taking a scene by performing range finding for a principal subject within a range finding area of a finder view field at a first stage of release member actuation and operating a shutter at a second stage of release member actuation: an apparatus for recording the position information of a principal image, said apparatus comprising: an area image sensor having a plurality of divided areas of which a central one of said divided areas is used for range finding; a memory for storing a time sequential signal of a principal subject outputted from said range finding area at the time of range finding; means for comparing said time sequential signal stored in said memory with time sequential signals from said respective divided areas so as to determine an area where said principal subject is present; and means for recording a code on a recording medium, said code being representative of said area where said principal subject is present at the time of photographing.
