Infrared focusing is according to transmitters imaging sensors relation between the positions of, through the geometric calculate and determine the position of the body was taken; Ultrasonic focus is according to launch wave and receive wave of time difference; Through the wave transmission time measurement is taken from the body.
Through the lens of imaging of the light is divided into two parts, with a photographic plate element in the equivalent of the plane of the two groups were imaging sensors. If focus on, the two sensors on the same position will get the same image; If the focal plane from photographic components, the image sensor also can appear migration; The camera SONY NP-BG1 Battery can detect offset, automatically adjust the camera position until focus accurately.

Automatic flash digital photograph the opportunity to determine the light is on flash and automatic control flash the canon eos 350d battery amount of light output.
Compulsory flash in any light environment, are open to flash flash. Usually used to the main body of the backlight for light. For example, when the subject back to the bright window when shooting.
Forced not flash that canon eos 450d battery close digital camera flash. This function can avoid interference with the object of flash was filmed apply to ban the use of flash photography occasion, in low light environment more without flash can build a natural photographing atmosphere.
Eliminate red eye model applicable to a waning light conditions on people close range, in dim light eye pupil will magnify, when flash light through the pupil to illuminate the retina, the capillary will reflect red light, so as to form the red eye phenomenon. Eliminate red-eye mode is usually the first flash the flash, make be taken of the object eyes constriction of the canon eos 1000d battery pupils, so as to make formal flash, eyeball won't appear too embarrassing among the red splash.
