Abstract:
Embodiments disclose a display apparatus including: an image processing device which processes an image signal; a display device which displays an image based on the processed image signal; a connection device which connects to an upgrade apparatus which processes the image signal; a power supply device which supplies power to each component of the display apparatus and the upgrade apparatus through the connection device; and a first controller which controls the connection device to receive the processed image signal from the upgrade apparatus when the upgrade apparatus is connected through the connection device, wherein the power supply device is controlled by the upgrade apparatus connected through the connection device.
Abstract:
Provided are an optical lens assembly and a method of forming an image. The optical lens assembly includes: a first lens having a convex object-side surface; a second lens having a convex object-side surface; at least one lens at an image side of the second lens; a first stop being a variable stop at an object side of the first lens; and a second stop at an image side of the first lens, wherein the second stop determines a minimum F number, and the first stop is variable to determine an F number greater than the minimum F number.
Abstract:
Provided are a photographic lens and an electronic apparatus including the photographic lens. The photographic lens includes a first lens having a negative refractive power; a second lens having a positive refractive power; a third lens having a negative refractive power and an image-side surface that is concave toward an image-side; a fourth lens having a positive refractive power; and a fifth lens having a negative refractive power. The first, second, third, fourth, and fifth lenses are arranged sequentially from an object-side to the image-side. Each of the first, second, third, fourth, and fifth lenses has at least one aspherical surface.
Abstract:
Provided are an optical lens assembly and an electronic device including the optical lens assembly. The optical lens assembly includes a front group closest to an object side and including a first lens having a positive refractive power and an image side surface that is concave, and a second lens having a negative refractive power, a third lens having a negative refractive power, and a fourth lens having a positive refractive power. Other embodiments may be provided.
