In a semiconductor package which contains an IC element therein and effects the inputting and outputting of a signal to the IC element through a plurality of pads, a group of signals is layout-patterned so as to be divided into a plurality of groups such as a group of signals weak against noise, a group of signals liable to discharge noise and a group of signals exchanging a heavy current and so that the groups may be isolated from one another.

Semiconductor package

In a camera in which a sensor receives reflected light from a subject during flash emission to control the amount of flash light emission on the basis of the output of the sensor, a plurality of focus detecting areas are provided within a light-receiving area of the sensor, and when one of the plurality of focus detecting areas is selected for focus adjustment, the camera sets an evaluation criterion for the output of the sensor in accordance with a position of the selected focus detecting area.

Camera for flash photography

The present invention provides a conveniently usable optical apparatus such as a camera which is provided with a visual axis detecting apparatus and a display portion in the field of view of a finder and which realizes a predetermined operating function which is not started when the finder observer is seeing the display portion and the like.

Optical apparatus capable of performing a desired function by gazing

The present invention relates to an information processing device for writing data into a computer incorporated in a camera body or reading data from the computer. According to the present invention, there is provided an information processing device which is inserted between the camera body and an accessory device to execute writing of data into the computer of the camera body or reading of data from the computer and to execute data communication between the computer of the camera body and the accessory device.

Information processing system for camera

A speed governor for a camera having a first speed governing means arranged to synchronously drive with an increased speed a driving member which drives a high speed operating member to a predetermined position and a second speed governing means arranged to brake the driving force of the driving member. The operating speed of the driving member is kept at a constant speed by the combined use of the first and second speed governing mean
