Electronic device comprising display operating in state for lower power consumption, and method therefor

An electronic device comprising:

• a display;
• memory, comprising one or more storage media, storing instructions;
• a sensor;
• and
• one or more processors including first processing circuitry, second processing circuitry, and at least one third processing circuitry,
• wherein the instructions, when executed by the first processing circuitry, cause the first processing circuitry to:
• store, in the memory, candidate images for at least partially changing a screen to be displayed on the display operating in a state for lower power consumption, wherein storing of the candidate images is performed for maintaining an inactive state of the first processing circuitry while the display operates in the state for lower power consumption, and
• after the candidate images are stored, switch a state of the first processing circuitry to the inactive state, and
• wherein the instructions, when executed by the at least one third processing circuitry, cause the at least one third processing circuitry to, while the inactive state of the first processing circuitry is maintained:
• control the second processing circuitry to obtain a candidate image corresponding to sensing data obtained via the sensor from among the candidate images, from the memory, and
• control the second processing circuitry to transmit data associated with the candidate image to the display for at least partially changing the screen being displayed on the display operating in the state for lower power consumption based on the candidate image.
