PROBLEM TO BE SOLVED: To provide a distance measuring device equipped with dual stereo camera which extracts more exact distance information.SOLUTION: The distance measuring device includes a left eye CMOS image sensor 113 and a right eye CMOS image sensor 115 which are arranged at the predetermined interval on one substrate, and a first stereo camera 110 which extracts the distance information by detecting parallax of a reference object, and separating from the first stereo camera 110 with the fixed distance interval, a left eye CMOS image sensor 123 and a right eye CMOS image sensor 125 which are arranged at the predetermined interval on one substrate, and a second stereo camera 120 which extracts the distance information by detecting parallax of the reference object. By comparison the distance information for the reference object obtained from the first stereo camera with the distance information for the reference object obtained from the second stereo camera, a distance map matching part 130 which is equipped extracts the distance information for the reference object.

PROBLEM TO BE SOLVED: To provide an apparatus and method for rotating an image embodied without using a memory.SOLUTION: The image rotation method includes the steps of (a) reading, by a JPEG encoder, an input image having m×n macroblocks (wherein "m" and "n" are natural numbers); (b)rotating image data of the respective macroblocks by a predetermined angle in a predetermined direction, when encoding in the JPEG encoder; (c) assigning and inputting a sequence of each rotated image data, when encoding in the JPEG encoder; (d) instructing the macroblocks so as to be output in a sequence changed from an initial input sequence of the macroblocks through use of a program, when decoding in a JPEG decoder; and (e) outputting an image rotated by the predetermined angle in the predetermined direction.
Abstract:
PROBLEM TO BE SOLVED: To provide an image sensor capable of measuring luminous intensity, proximity, and color temperature that can measure current luminous intensity, proximity to an object, and color temperature of the object by using a variation in an output voltage value according to the existence or absence of infrared and visible ray with a wavelength in a specific band. SOLUTION: The image sensor capable of measuring the luminous intensity, proximity, and color temperature includes separate second sensing portions that are provided around a first sensing portion having an image pixel and are configured to operate separately from the first sensing portion, thus making it possible to reduce power consumption and to easily measure current luminous intensity, proximity to an object, and color temperature of the object.
