TH17949EX - Cameras that are able to detect insufficient light output and how to control them. - Google Patents

Abstract

A camera capable of detecting and indicating insufficient flashes of illumination, which can indicate inadequate illumination when objects are far away and in low illumination conditions. The processor in the center of the camera's CPU is connected to a block switch. With power switch First step disconnect switch Second ejection switch and flash detection switch attached to the camera. Take pictures, it also includes an auto-distance meter, a brightness meter, a flash assist, and a reminder. Such CPUs will provide user information. Used that the flash should be used when it is determined that the brightness is lower than the preset minimum brightness and subject. Is too far away to be sufficiently illuminated

Claims (1)

1. A camera capable of detecting insufficient light output contains A path for measuring the distance from the subject to the camera. A path for measuring the ambient brightness around the object. A path for comparing the distance measured by the trajectory. Measure such distance and the ambient brightness measured by trajectory. Measure such brightness And produce control signals Main flash path for optimal distribution of illumination Responding to signals from such control methods When the distance from the object Measured by the distance measuring method Within the maximum photographic distance where
