JPS62262821A - Auxiliary apparatus for spectacle frame selection - Google Patents

Abstract

PURPOSE:To simultaneously display a state of wearing a pair of spectacles, on plural television monitors at the time of selecting said frame,and to easily execute its comparison and contrast, by constituting the titled equipment so that a controller part is provided with a function which can execute a multi- screen split display. CONSTITUTION:Photographing is executed by pointing a television camera 1 to an object to be photographed, and its image is converted to a digital signal through an analog-to-digital converter 3 by operating a VTR switch belonging to the television camera, stored temporarily in a dual port memory 4, and thereafter, stored in a dynamic RAM 7. As for a necessary storage capacity, a four-screen portion is usual enough for selecting a spectacle frame, and when it is used for a two-screen split display, eight screens can be stored. A two- screen split display or a one-screen display is selected by a control switch 13 and a switch interface 14. As for an image whose half screen is inputted, it is combined optionally and read out by a CPU 9, a DMA controller 10, a ROM 11, and a RAM 12, returned to its original one signal, and reproduced and displayed on a television monitor.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention provides an auxiliary device for selecting eyeglass frames, and more specifically, it provides an auxiliary device for selecting eyeglass frames by comparing and contrasting the state in which the eyeglass frames are worn on a television monitor. It relates to auxiliary equipment that facilitates selection.

BACKGROUND OF THE INVENTION When selecting articles to be worn on the body, it is common to judge the condition of the various articles being worn, either directly or using a mirror. However, such judgments are often insufficient, even when considering individual tastes. This is because the nuances are slightly different from looking at it from a third-person perspective. Also, some people who use glasses to correct their vision cannot even see their own faces in the mirror without them.

This person cannot see through a mirror while wearing eyeglass frames without lenses.

Therefore, recently, recording and playback using a VTR is sometimes used to select eyeglass frames. However, this method is complicated to operate. Another drawback is that sufficient comparisons cannot be made due to the limitations of human memory.

It is an object of the present invention to provide an eyeglass frame selection auxiliary device which is equipped with a multi-screen split display function to facilitate comparison and contrast, and has greatly improved operability such as instantaneous screen switching.

Structure of the Invention In order to achieve the above-mentioned object, the present invention comprises a television camera, a video memory section that stores images taken by the television camera as still images, a controller section that controls the video memory section, and a television monitor. It is characterized in that the section is equipped with a function that allows multi-screen split display.

The present invention will be explained below based on drawings of embodiments.

FIG. 1 is a block diagram of one embodiment, and FIG. 2 is an example of a two-screen split display based on FIG.

(1) is a TV camera, (2) is an RGB decoder, (3
) is an analog-to-digital converter, (4) is a dual-port memory, (5) is a digital-to-analog converter, (6)
is an RGB encoder.

<7) is a dynamic RAM and is controlled by a dynamic RAM controller (8). (9) is the CPU,
(10) is a DMA controller, (11) is RoMl
(12) is a RAM, and a control switch (13)
), the necessary instructions are given by the switch interface (14).

With the above configuration, the TV camera (1) is directed toward the subject, and by operating the VTR switch attached to the TV camera, the image is converted into a digital signal via the analog-to-digital converter (3). Convert and dual port memory (4
), and then stored in the dynamic RAM (7). The required storage capacity varies depending on the method of use, but four screens are usually sufficient for selecting eyeglass frames. If used for two-screen split display as shown in FIG. 2, eight screens can be stored. A control switch (13) and a switch interface (14) are used to select whether to display a two-screen split screen or a single screen display.

For images input in half screen, CPU (9), DM
AD: zto D-7 (10), ROM (11), RA
M (12) is read out in arbitrary combinations,
Dual port memory, digital to analog converter, RG
It is returned to the original single signal via the B encoder (6) and reproduced and displayed on a television monitor.

Effects of the Invention As is clear from the above description, according to the present invention, when selecting eyeglass frames, images can be displayed simultaneously on a plurality of television monitors while the eyeglass frames are being worn, thereby facilitating comparison and comparison.

Furthermore, even those who cannot use a mirror due to large refractive errors can compare and contrast images without any trouble by using a trial frame or the like. Furthermore, maintenance costs can be kept low because films, tapes, etc. are not required.
