A video display device comprising: a display unit that displays one of a 3D video and a 2D video in a switching manner; face detection means for detecting a face and facial organs of a user from an image generated by imaging means; image selection means for estimating a utilization status of the user by analyzing features of the face detected by the face detection means, and selecting, based on a result of the estimation, whether to display the 3D or 2D video, and configured to measure, by a method for counting the number of pixels of a face image detected by the face detection means, a size of a face and a distance between each facial organ detected by the face detecting means for obtaining measurement data and to estimate a position of the user with respect to the display unit, based on the size of the face and the distance between facial organs detected by the face detection means; registration means in which reference data, which are based on an analysis of images of a considerable number of persons at a location away by a standard viewing distance from the display unit, on the size of a face image and the distances between facial organs are registered, wherein the image selection means is further configured (i) to extract, from the measurement data, measurement data whose difference with the reference data is within a predetermined allowable value, (ii) to determine a number of the extracted measurement data and (iii) to estimate the user's position based on the determined number, to select to display the 3D video when the determined number exceeds a predetermined threshold value; and to select to display the 2D video when the determined number is less than or equal to the threshold value; and display control means for outputting the video selected by the image selection means to the display unit, wherein the image selection means is further configured to select to display the 3D video when each measurement data is larger than the reference data although the determined number is less than or equal to the threshold value; and the display control means is configured to reduce an image display area on the display unit when each measurement data is larger than the reference data and the determined number is less than or equal to the threshold value, and to display the 3D video on the reduced image display area. a display unit that displays one of a 3D video and a 2D video in a switching manner; face detection means for detecting a face and facial organs of a user from an image generated by imaging means; image selection means for estimating a utilization status of the user by analyzing features of the face detected by the face detection means, and selecting, based on a result of the estimation, whether to display the 3D or 2D video, and configured to measure, by a method for counting the number of pixels of a face image detected by the face detection means, a size of a face and a distance between each facial organ detected by the face detecting means for obtaining measurement data and to estimate a position of the user with respect to the display unit, based on the size of the face and the distance between facial organs detected by the face detection means; registration means in which reference data, which are based on an analysis of images of a considerable number of persons at a location away by a standard viewing distance from the display unit, on the size of a face image and the distances between facial organs are registered, wherein the image selection means is further configured (i) to extract, from the measurement data, measurement data whose difference with the reference data is within a predetermined allowable value, (ii) to determine a number of the extracted measurement data and (iii) to estimate the user's position based on the determined number, to select to display the 3D video when the determined number exceeds a predetermined threshold value; and to select to display the 2D video when the determined number is less than or equal to the threshold value; and
