PROBLEM TO BE SOLVED: To enable simultaneous command setting to the same kind of plural devices (imaging device or the like) using a serial I/F bus (I2C bus) with a simple configuration without requiring a complex processing.SOLUTION: An I2C control circuit 320, and SDA1 and SDA2 of imaging elements 11 and 12 are connected through input/output selectors 330 and 340. When a command or the like is to be set to the imaging elements 11 and 12, SDA output of the I2C control circuit 320 is connected to both of the SDA1 and SDA2 through the output selector 330. Either the SDA1 or the SDA2 is connected to SDA input of the I2C control circuit 320 through the input selector 340. With the configuration, simultaneous setting of a command or the like to the imaging elements 11 and 12 is made possible according to normal I2C communication protocol with I2C control circuit 320 as the master device and the imaging elements 11 and 12 as slave devices.SELECTED DRAWING: Figure 6 |
