This standard is based on 2907931 Film—35 mm film! This standard is about to revise the national projection area and size of films. The technical content and writing principles of this standard are consistent with IS2)/:1934. It was signed in the early 1960s with the 1S0250/1S7235 film projection screen, and the national projection area and size of films that can be projected are determined by the 1S02. It is called the 85mm film microfilm projection screen - the largest projection area and size that can be projected. In the new standard, the basic technical parameters of the service items have not changed, but the standard "the height and stability of the film" is added after the main text of the standard, and the width ratio of the film and the environmental requirements of the picture are given. The national standard is adopted. 13) 20071984, the name of G3/1636 was changed to 335mr. The standard "the height of the film can be placed on the surface" was added, and some of the items were improved with reference to 152907: 1%. The appendix of this standard is the preparation of the standard. This standard is proposed by the State Administration of Radio, Film and Television. This standard is under the jurisdiction of the China Film Academy. This standard was drafted by China Film Academy and Technology Institute. This standard was first drafted in 1999 and this revision is the first revision. This standard was entrusted to China Film Academy and Technology Institute for interpretation. GT463E—2D0C
TSO Foreword
International Standardization Organization (TSO) is a joint organization of member organizations of the industry. The formulation of international standards is completed through the relevant technical committees. Any member organization that is interested in the technical committee has the right to send a representative to participate in the technical meeting. Other non-governmental organizations (NGOs) may participate in this work. Before the international standard drafts passed by the international standard committee are approved by the international standard committee, they will be circulated to various organizations for comments.
International Standard E0) 297 was developed by TS0/TC: Technical Committee on Motion Picture. It was distributed to all countries under the Standardization Act in February 1983. The member bodies of the system that voted for this standard are the following: Belgium

The various sizes are shown in the figure and Table 1. These numbers are used in a timely manner, such as the maximum projection device on the electronic transfer and washing process. The entire plan is often recorded. The actual projection surface may be smaller than the maximum projection surface. Therefore, the actual projection surface is required to be the correct surface under the conditions of Table 14.

The subject is that the non-anamorphic film has a wide range of projection images and the internal width ratio is obtained (see Table 2). A2 The actual projection surface
In most cases, the projection image can be smaller than the maximum projection image. The reason for this difference may be the equipment, such as the camera head, which can be used to reduce the size difference. The optical axis does not need to be raised or lowered, and the gear teeth do not need to be changed. The actual design should be based on the new size and the shape of the standard can be obtained. Note that under various circumstances, the resolution of both sides can be quickly returned to the underwater center of the axis of symmetry, the non-deformed image and the copy of the image can be reflected on the surface of the image. The stability of the image is produced by the film's reference effect. The m-surface compensation theorem can be improved, and the surface height H is 12-52.
