Claims
- 1. A camera with a sight line detecting apparatus comprising:
- sight line detecting means for detecting a photographer's line of sight;
- time counting means for counting time;
- watching point determining means for judging a watching point based on outputs of said sight line detecting means and said time counting means;
- watching point information storing means for storing therein a plurality of bits of watching point information time-serially calculated by said watching point determining means; and
- record renewing means for recording and renewing said plurality of bits of watching point information in said watching point information storing means;
- said record renewing means preferentially erasing the watching point information having a shortest watching time and recording a newest watching point information when the newest watching point information is calculated and when said watching point information storing means is saturated.
- 2. A camera with a sight line detecting apparatus according to claim 1, wherein said watching point determining means is designed to calculate watching point information based on a time when watching has been started, a watching time and a watching position.
- 3. A camera with a sight line detecting apparatus according to claim 1, further comprising range means capable of measuring a range in each of a plurality of range areas, and range area selecting means for selecting one of said plurality of range areas of said range means based on said plurality of bits of watching point information.
- 4. A camera with a sight line detecting apparatus according to claim 2, further comprising range means capable of measuring a range in each of a plurality of range areas, and range area selecting means for selecting one of said plurality of range areas of said range based on said plurality of bits of watching point information.
- 5. A camera with a sight line detecting apparatus comprising:
- sight line detecting means for detecting a photographer's line of sight;
- time counting means for counting time;
- watching point determining means for judging a watching point based on outputs of said sight line detecting means and said time counting means;
- watching point information storing means for storing therein a plurality of bits of watching point information time-serially calculated by said watching point determining means;
- watching point information renewing means for recording and renewing said plurality of bits of watching point information in said watching point information storing means; and
- correcting means for correcting said plurality of bits of watching point information stored in said watching point information storing means;
- said correcting means calculating weighted watching point information by weighting said plurality of bits of watching point information stored in said watching point information storing means differently depending upon an elapsed time from the time when said plurality of bits are judged to be a watching point.
- 6. A camera with a sight line detecting apparatus according to claim 5, further comprising range means capable of measuring a range in each of a plurality of range areas, and range area selecting means for selecting one of said plurality of range areas of said range means based on said weighed watching point information.
- 7. A camera with a sight line detecting apparatus according to claim 5, further comprising light metering means capable of effecting light metering in each of a plurality of light metering areas, and light metering value calculating means for calculating a final light metering value in each of said light metering areas based on a metering output of said light metering means and a weighting factor.
- 8. A camera with a sight line detecting apparatus for detecting a photographer's line of sight, wherein, when new watching point information is produced by outputs of a time counting circuit for counting time and said sight line detecting apparatus, and a memory element capable of storing a plurality of watching point information is saturated and can not store said new watching point information, a watching point information having a shortest watching time of watching point information already stored in said memory element is erased and said new watching point information is stored.
- 9. A camera with a sight line detecting apparatus for detecting a photographer's line of sight, and which is provided with a time counting circuit for counting time and a memory element storing a plurality of watching point information produced by said time counting circuit and said sight line detecting apparatus, wherein the plurality of watching point information stored in said memory element is weighted differently according to an elapse of time from the time when said plurality of watching point information are judged to be a watching point.
