Title: Albada type finder
Inventor: KONO TSUTOMU
IPC: G02B13/18
Filed: 1995-12-06
Abstract: PROBLEM TO BE SOLVED: To obtain an inexpensive wide-angle Albada type finder whose entire length is short by making both surfaces of a 1st lens aspherical. SOLUTION: This Albada type finder is constituted of the 1st lens having negative refractive power, a 2nd lens having an Albada type half mirror surface, and a 3rd lens provided with a reflecting member or a light emitting member showing a visual field frame on any lens surface on an object side or an image side in order from the object side, and used at the angle of view being >=60 deg.; and both surfaces of the 1st lens are made aspherical. By making both surface of the 1st lens aspherical, astigmatism and distortion aberration are excellently corrected even in the case of incident light having the angle of view being >=60 deg. by the lens constitution having small number of lenses such as three lenses of three groups. However, the distortion aberration is excessively corrected and becomes barrel form distortion.  Then, the lens surface on the object side of the 1st lens is made aspherical so that the curvature at a distant part from an optical axis may be intenser than that in the vicinity of the optical axis. By making the distortion aberration pincushion distortion, the distortion aberration is corrected.

Abstract: PURPOSE:To display a drawn curve approximate to a curve imaged by an operator on a display picture by automatically smoothing a line drawn by the cursor is more than a previously determined value and redrawing the line. CONSTITUTION:A CPU 31 is provided with a means for detecting the moving speed of the cursor, and when the cursor is moved from a point A to a point B e.g. for a unit time, a moving distance per unit time is detected on the basis of the deformation of coordinates (DELTAx, DELTAy) sent from a mouse 32. When the values DELTAx, DELTAy are more than a fixed value for a certain period, i.e. when the mouse moving distance per unit time is larger than the fixed vale, smoothing processing is unconditionally executed. Consequently, a smoothed curve can be obtained and a curve extremely approximate to a curve imaged by the operator can be obtained.
