CONTROL APPARATUS, CONTROL METHOD, PROGRAM, AND ELECTRONIC DEVICE SYSTEM THAT PROVIDE LOW POWER CONSUMPTION

The present technology relates to a control apparatus, a control method, a program, and an electronic device system that enables achievement of low power consumption.The presence or absence of a preset, predetermined subject is detected from an image having a low resolution output by an image sensor in a low power consumption mode, the image sensor including, as operation modes, the low power consumption mode in which the image having the low resolution is output and a normal mode in which an image having a high resolution as compared with the image having the low resolution is output. Then, in a case where the presence of the predetermined subject is detected, the operation mode of the image sensor is set to the normal mode, and the image sensor outputs the image having the high resolution. The present technology may be applied, for example, to control of the image sensor.
