Abstract: An embodiment discloses an electronic device including: a first memory in which multiple applications are stored; a second memory; and at least one processor operatively connected to the first memory and the second memory. The processor(s) is configured to determine, based on a history of usage of the multiple applications for a first period of time, a priority of the multiple applications over multiple time intervals included in a second period of time. The processor(s) is further configured to preload a predetermined first number of applications into the second memory based on the priority if a designated condition being satisfied; and preload a first list of applications into the second memory if the designated condition is satisfied in a first time interval, and preload a second list of applications into the second memory if the designated condition is satisfied in a second time interval.

Abstract: An image processing device includes a memory and a color correction circuit. The memory stores first correction information that used for correcting first pixel values among a plurality of pixel values. The plurality of pixel values are received from an auto-focus image sensor including first pixels configured to detect a phase difference and second pixels configured to detect an image. The first pixel values are obtained from the first pixels and correspond to a first color. The first correction information is used for correcting the first pixel values to correspond to a second color different from the first color. The color correction circuit receives first image frame data including the plurality of pixel values from the auto-focus image sensor, loads the first correction information from the memory, and generates first corrected image frame data by correcting the first pixel values included in the first image frame data to correspond to the second color based on the first correction information.

Abstract: A method and an apparatus for controlling an air conditioner are provided. The method includes sensing, by an air conditioner control apparatus, a user action requesting a temperature control, checking whether one of a common control mode in which a setting temperature is controlled at a first temperature control interval and a minute control mode in which the setting temperature is controlled at a second temperature control interval, which is less than the first temperature control interval, is selected in response to the sensed user action, calculating the setting temperature based on the user action and a result of the checking, and transmitting the calculated setting temperature to the air conditioner.

Abstract: Disclosed is an electronic device which includes a processing block, a crosstalk compensation block, and a dark level compensation block. The processing block receives image data from an active pixel region of an image sensor and performs pre-processing on the image data. The crosstalk compensation block performs crosstalk compensation on the pre-processed image data. The dark level compensation block performs the crosstalk compensation on dark level data received from an optical black region of the image sensor and performs a subtraction operation on the crosstalk-compensated image data and the crosstalk-compensated dark level data.
