Abstract: A plant cultivation apparatus is provided. The plant cultivation apparatus may include a cabinet, a bed, and a light emitting portion. A cultivation portion, which is provided inside of the cabinet and in which at least a portion of a plant is embedded, rests on the bed. The light emitting portion is provided inside of the cabinet d emits light toward the cultivation portion. The light emitting portion includes a light emitting body that emits light toward cultivation portion, and a lens located between the light emitting body and the cultivation portion. Light provided from the light emitting body is provided to the cultivation portion by being transmitted through the lens. The lens includes a first lens through which the light from the light emitting body is transmitted so as to have a first radiation angle, and a second lens through which the light from the light emitting body is transmitted so as to have a second radiation angle, which is less than the first radiation angle. The lens is configured such that the light provided from the light emitting body is selectively transmitted through either the first lens or the second lens.

Abstract: For improving AF performance, the mobile terminal includes a liquid lens, a storage configured to store a focal length based on applied voltages at two or more reference temperatures and a valid voltage range corresponding to a valid focal length range at the two or more reference temperatures, and a controller configured to perform compensation on the valid voltage range based on the temperature measured by the temperature sensor, wherein the controller is configured to perform shift-compensation on the valid voltage range when the measured temperature is greater than or equal to a first threshold temperature, a shift amount corresponding to the shift-compensation being a value obtained by applying an interpolation to a shift amount at the two or more reference temperatures, and perform extension-compensation on the valid voltage range when the measured temperature is less than the first threshold temperature.
