Digital camera from SONY Digital Camera Battery the point of view of the applicable object can be divided into consumer digital cameras and digital SLR camera DC (DSLR).
APS called advanced photography system, is a kind of due to the rapid development of digital photography and be washed out film photography system. There are three kinds of size film APS: the APS-C, APS-H, APS-P. H is a full picture (30.3 mm x 16.6 mm); C (24.9 mm x 16.6 mm) is in the full picture about the two head to the block a, aspect ratio for 3:2; P type (30.3 mm x 10.1 mm) SLR is SONY NP-BN1 Battery used this one standard and close to the size of the C 22.5 mm x 15.0 mm and 23.6 mm x 15.8 mm all are called APS-C format, and 28.7 mm x 19.1 mm is called the APS-H format.
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.
