摘要： PROBLEM TO BE SOLVED: To solve a problem of a training machine equipped with a stationary bicycle, with which a user takes exercise by pushing loaded pedals, that the exercise is dull and the user tends to get bored in the exercise and stop the exercise halfway. SOLUTION: This training machine is for making the exercise which tends to be dull more enjoyable. A user runs a stationary bicycle just like an ordinary training machine. An interface device 2 converts the angle of the handleber of the bicycle from analog signals to digital signals, and the rotational frequency of pedals of the bicycle is counted by a counter. Based on the angle of the handlebar and the rotational frequency of pedals, the position of the bicycle is calculated by a personal computer 3. The calculated position of the bicycle is marked on a map and displayed on a display device 4. Therefore, the user can enjoy the exercise without getting bored, watching the display.

摘要： PROBLEM TO BE SOLVED: To correct a display distortion and to enable accurate display by inputting X and Y coordinates to display prescribed video in a prescribed bearing, reading out the contents of a memory in which coordinate values to be corrected corresponding to these coordinates are previously stored, converting a scanning position and correcting the video projected on a display screen. SOLUTION: A scanning position generating circuit 1 is composed of a counter for counting a clock with one pixel as a minimum unit and generates lateral and longitudinal pixel positions X1 and Y1 synchronously with the synchronizing signal of video. A scanning position converting memory 2 outputs pixel positions X2 and Y2 corresponding to the input pixel positions X1 and Y1. The memory 2 previously stores conversion data for correction. Concerning the correction data, a value is set so as to output the input X1 and Y1 as they are as initial data first of all and the point of a known watching bearing is displayed through a liquid crystal panel 3 for projection onto a display screen 4.

摘要： PURPOSE:To obtain a miniature, inexpensive zoom lens of high magnification, by using an ordinary zoom lens and extender and by controlling them relatively. CONSTITUTION:When voltage v that corresponds to zoom ratio (l) to be set in comparator 1 and voltage vn that corresponding to maximum zoom ratio (n) of zoom lens 5 are inputted to the comparator while v >=vn, comparator 1 outputs extender input signal E. When this input signal E is on, extender 4 is held inserted, namely, magnification (m) is set. On the other hand, zoom ratio (l) is set to i/m (m

摘要： PROBLEM TO BE SOLVED: To find out the best adjustment point in a short time. SOLUTION: The adjustment method of the display device is automated. That is, based on a video signal from pluralities of video projectors 21, 22 having edge blend processing units 31, 32 and from a video camera 4 that photographs an edge blend part 10 on a display screen 1 to display a video image, the start point and the end point of edge blend are section decided and the luminance is automatically corrected so that the change in luminance from the start point to the end point of is linear thereby conducting optimum setting.
