    • Disclosed are a mobile communication terminal and a method capable of taking a high-quality picture by providing a flash or light function according to ambient luminance when a camera mounted in the mobile communication terminal takes a picture. The mobile communication terminal equipped with a camera includes: a luminance sensor unit for outputting an analog electrical signal proportional to ambient luminance; a control unit for generating a preview light enable signal according to the analog electrical signal; and a preview light for emitting light in a preview mode in response to the preview light enable signal. In addition, a method of controlling a mobile communication terminal equipped with a camera unit and a light unit includes the steps of: enabling a luminance sensor unit to detect ambient luminance according to a camera mode selection command; comparing a light intensity value obtained from a signal outputted from the luminance sensor unit with a pre-programmed threshold value; and controlling the operation of the light unit according to the comparison result.

    • An analog-to-digital converter includes a first logic unit and a second logic unit. The first logic unit is configured to receive a plurality of thermometer codes and inverse thermometer codes generated based on an analog signal received by the analog-to-digital converter and to generate a plurality of first digital codes that periodically repeat the same pattern based on a transition position of a logic value in each of the thermometer codes and the inverse thermometer codes. The second logic unit is configured to receive the plurality of first digital codes and to generate a plurality of second digital codes based on logic values of a plurality of bits among all bits of each of the first digital codes.
