Title: Photometer for camera
Inventor: YOSHIZAWA AKIHIRO
IPC: G03B7/08
Filed: 2000-04-19
Abstract: PROBLEM TO BE SOLVED: To accurately perform exposure arithmetic operation even when an error is generated in a luminance value outputted from a photometer. SOLUTION: This photometer 2 detects subject light in photometric areas 320a to 320e (figure 3) respectively and transmits photometry output to an MCU1. The MCU1 obtains the luminance values BV1(a) to BV1(e) corresponding to the respective photometric areas. A range binder 3 picks up an object image by the object light in image pickup areas 330a to 330c (figure 3) respectively and stores image data in a memory 34. The MCU1 reads out the image data from the memory 34 and obtains the luminance values BV2(a) to BV2(c) corresponding to the respective image pickup areas from the image data.  When a difference between the luminance values obtained in the corresponding photometric area and the corresponding image pickup area is equal to or above a specified value K, the MCU1 calculates an exposure control luminance value BV(M) by making the luminance value by the photometer 2 in the corresponding area ineffective and using the luminance value by the range binder 3 in the corresponding area instead of the luminance value. The MCU1 decides a control diaphragm value and a control shutter time by using the exposure control luminance value BV(M).
