Title:
CAMERA
Document Type and Number:
Japanese Patent JP2004101909
Kind Code:
A
Abstract:
To provide a high-performance multi AF camera having an inexpensive and simple constitution by effectively using inexpensive parts.
The light of the object image is received by a range-finder IC 6 to start integration from a first voltage level. A/D conversion is carried out by an A/D converter 11 with a second voltage lower than the first voltage level as the maximum. The output voltage of the output circuit of the range-finder IC 6 is divided by series resistors 8 and the divided output voltage or the voltage signal prior divided is inputted into the A/D converter 11. The distance signal to the object is calculated by an operation control part 12 based on the output of the A/D converter 11.
