Patent number: 10708483Abstract: The present technology relates to an information processing device and an information processing method, a solid-state imaging device and a solid-state imaging device operation method, a program, and an electronic apparatus in which an IC having an AF lens drive control unit mounted therein is made compatible with various communication specifications that vary with the types of lens driver ICs to be connected. A digital analogue converter (DAC) code for controlling a lens driver IC that controls driving of an actuator that drives a focusing lens is generated. A communication format related to serial communication is set in accordance with the lens driver IC, and is stored. The DAC code is buried in the communication format, to form a format compatible with the lens driver IC. Control is performed to cause the DAC code to be transmitted to the lens driver IC through serial communication. The present technology can be applied to imaging apparatuses.Type: GrantFiled: July 15, 2016Date of Patent: July 7, 2020Assignee: Sony Semiconductor Solutions CorporationInventors: Minoru Kaihatsu, Shinichi Ohtsubo, Riichi Ono, Hiroaki Anai
