Abstract
A camera apparatus includes an optical image stabilizer (OIS) device including a control circuit controlling data processing including reading data and writing data, and a digital circuit including a serial peripheral interface bus (SPI) master performing data processing based on SPI communications performed using the SPI master under control of the control circuit to perform an OIS function; and a sensor device including an SPI slave communicating with the SPI master and responding to a request from the OIS device. The control circuit sets a selected SPI communications mode selected from a plurality of predefined SPI communications modes. The digital circuit performs the selected SPI communications mode, and in response to the selected SPI communications mode being a burst status mode with a status check, checks two or more status bits for corresponding data to be read from the sensor device before reading the corresponding data from the sensor device.
