Abstract: A distance measurement apparatus for use in a camera having a CPU. The apparatus has no analog distance-measuring IC and can yet perform active distance measuring. It comprises an infrared-emitting diode (IRED), a light-receiving element and an integration circuit, both connected to the ports of the CPU. In operation, the IRED emits an infrared beam toward an object. The light-receiving element receives the beam reflected form the object and stationary light and converts the beam and the light into an electric signal. The integration circuit integrates the electric signal. The CPU measures a first period of time lapsing from the time when the the integration circuit is initialized to the time when the output of the integration circuit increases over a predetermined value. The CPU also measures a second period of time lapsing from the time when the the integration circuit is initialized to the time when the output of the integration circuit increases over the predetermined value while the IRED is emitting no infrared beam. From the first and second periods of time, thus measured, the CPU determines the distance at which the object is located, not influenced by from the stationary light at all.

Abstract: A ranging apparatus according to the present invention can execute accurate focusing even when photography is performed in, for example, an environment in which the background of a main subject to be photographed is a night view. This accurate focusing is executed by performing two pre-integration operations, one with light projection and the other without light projection, then comparing signal patterns obtained by the two pre-integration operations to thereby select a partial area of a line sensor, which shows a difference between the signal patterns obtained by the comparison, and mainly using an output from this area as a signal for ranging. Further, this ranging apparatus performs pre-emission before the ranging operation, using the line sensor to set the ranging area of the apparatus substantially equal to an image area to be shot, thereby determining the position of the main subject in the image area to be shot. Thus, the ranging apparatus can select a desired subject without focus lock operations.

Abstract: In a main body of a camera, a recording unit is disposed which is capable of recording specific information of a photographing lens or an accessory. When the specific information of the presently attached photographing lens or accessory has been already registered in the recording unit, the main body of the camera does not acquire all the specific information from the attached photographing lens or accessory by data communication. In a case where the specific information of the attached photographing lens or accessory has been registered in the recording unit, the only identification information of the interchangeable lens or accessory can be enough, even if the data communication is necessary. In consequence, a communication time with respect to the interchangeable lenses or various types of accessories can be reduced as a whole.

Abstract translation: 在相机的主体中，设置有能够记录拍摄镜头或附件的特定信息的记录单元。 当当前附着的拍摄镜头或附件的具体信息已经被记录在记录单元中时，照相机的主体不通过数据通信从附加的拍摄镜头或附件获得所有特定信息。 在附着的拍摄镜头或附件的具体信息已经被登记在记录单元中的情况下，即使需要数据通信，也可以只使用可互换镜头或附件的识别信息。 因此，相对于可互换镜头或各种类型的附件的通信时间整体上可以减少。

Abstract: The present invention comprises a first distance-measuring mode in which a subject distance is measured on the basis of a subject image signal produced by at least a pair of integration-type light-receiving elements receiving the light from subjects, and a second distance-measuring mode in which the subject distance is measured on the basis of the image signal a steady-light removing section has produced by removing the steady-light component from the subject image signal. In measuring the distance, the second distance-measuring mode is forced to be on for a specific time. On the basis of the resulting image signal, the main subject is estimated and a light-receiving sensor sensing area is selected. The light-receiving sensor sensing area is used for integration control in continuing to obtain the subject image signal.
