Camera unit with light steering mechanism and the application thereof

A camera unit with a light steering mechanism, the camera unit comprising:

• a long-focal-length camera module;
• and
• a wide-angle camera module, wherein
• the wide-angle camera module provides a wide-angle image, and a ratio between an equivalent focal length of the long-focal-length camera module and an equivalent focal length of the wide-angle camera module is not less than 4,
• the long-focal-length camera module includes a light steering mechanism, a long-focal-length lens and a long-focal-length photosensitive assembly,
• the light steering mechanism is configured to turn light to pass through the long-focal-length lens to be received by the long-focal-length photosensitive assembly,
• a height dimension of the long-focal-length camera module does not exceed 5.6 mm,
• a first surface of the long-focal-length lens has a first height h, and a diagonal length of a photosensitive area of a photosensitive element of the long-focal-length photosensitive assembly is L, where h and L satisfy the following condition:
• h/L≥0.8,
• L is reduced by reducing a number of photosensitive units in the photosensitive area of the photosensitive element and increasing a size of the photosensitive units,
• a dimension A of one of the photosensitive units is A≥1.2 μm, and
• a diameter D of an aperture of the long-focal-length lens satisfies the following condition:
• 5.3 mm≥D≥3.76 mm.
