摘要: At least one electro-optical light shielding member is disposed close to a reticle of a photographic camera arranged for forming an image of an object to be photographed. The light shielding member is electrically controlled to have the reticle partly light-shielded by the light shielding pattern of the light shielding member in such a manner as to permit selection between an averaging light measuring mode and a spot light measuring mode.

摘要: A light measuring device for a camera which can change between light measuring ranges is achieved by dividing a transparent light condensing member into two or more portions of different optical characteristics and electrooptically actuating one or more light shading members for shading the object light passing through the light condensing member to a sensor.

摘要: Creases are formed in a cellulosic fiber textile by treating the fiber textile with liquid ammonia, creasing the fiber textile, and treating the fiber textile with hot water or alkaline solution substantially simultaneous with or subsequent to the creasing step. Fully durable creases are formed in the cellulosic fiber textile without detracting from strength.

摘要: There is disclosed a device for correcting the accumulation time of a photoelectric converter composed of self-scanning charge-accumulation elements of plural bits on the basis of the average intensity to the incident light to the converter. The charge accumulation time is controlled by determining a reference value according to the maximum value of the output signals obtained from the photoelectric converter and comparing this reference value with the average intensity.
