IPC: G03B17/00
Filed: 1985-03-01
Abstract: PURPOSE:To improve the display effect of the remaining number of film frames by displaying the number of film frames with a bar pattern when the number of film frames is large and numerically when the remaining number of frames becomes small. CONSTITUTION:A liquid-crystal display device 14 is dedicated to film information display in averaged light metering mode and displays the rest of a film with a bar graph pattern 16. Namely, every six film frames correspond to one pattern and when a film having >=36 frames is loaded, six patterns illuminate at intervals of two bars. A photograph is taken in this state and then one bar turns off for every fix frames so that five bar patterns corresponding to 35-36 remaining frames and four bar patterns corresponding to 29-24 frames illuminate. When there are 11-10 frames left, one bar pattern illuminates and when the number of frames decreases to <=9, the film rest display is switched over from the bar pattern display to 7-segment digital display. Thus, the display effect of the remaining number of film frames is improved.

Title: Information recording system
Inventor: TSUNODA YOSHITO
IPC: G11B9/06
Filed: 1983-03-14
Abstract: PURPOSE:To record a large capacity of digital information, by reducing a clock frequency by a specific quantity each time when an optical head is moved for a specific length from the outermost track position of an optical disc in the direction of radius. CONSTITUTION:When information is recorded on an optical disc 1, where the radius of the outermost track is (r), with a constant frequency (f), a capacity C is expressed by C={(r-ri/P}X2piri/a (a, P, and ri are the diameter of a hole for recording of one pit of digital information, the track picth, and the radius of the innermost track of information recording respectively). By this equation, the capacity C is maximum when ri=r/2 is true. When the clock frequency is set to a half of the clock frequency (f) and information is recorded from the part of the radius r/2 to the part of the radius r/4, a maximum capacity of information is recorded there. Hereafter, the clock frequency is changed to 1/2 successively each time when the radius of the track is reduced to 1/2; and thus, the capacity of information recorded when the clock frequency (f) is reduced up to f/8 is 1.33 times as large as the capacity of information which is recorded without changing the clock frequency.
