Abstract: A method for controlling a photographing apparatus with a display screen includes detecting a sliding operation on the display screen and switching a display interface in response to the sliding operation. If the sliding operation is a first operation mode, the display interface is switched to a photographing mode setting interface. If the sliding operation is a second operation mode, the display interface is switched to a photographing function setting interface. If the sliding operation is a third operation mode, the display interface is switched to a playback control interface.

Abstract: An imaging device includes a lens and a circuit configured to control the lens to move in a first direction along an optical axis of the lens, control capture of a plurality of first images via the lens when the lens is positioned at a plurality of first positions, respectively, control the lens to move in a second direction opposite to the first direction, control capture of one or more second images via the lens when the lens is positioned at one or more second positions, respectively, and determine a focus position based on one or more of a plurality of first evaluation values calculated from the plurality of first images and one or more second evaluation values calculated from the one or more second images. Each of the plurality of first evaluation values and the one or more second evaluation values indicates a corresponding focus state.

Abstract: A control device includes a circuit configured to derive a plurality of focus state values representing focus states for each region of a plurality of regions within an image captured by a camera device, and perform a focusing control of the camera device based on a value of the plurality of focus state values representing a closest focus state.

Abstract: A control device includes a processor and a memory storing instructions that, when executed by the processor, cause the processor to obtain temperature information measured by a temperature sensor of an imaging device and perform adjustment on a focus position of a lens of the imaging device in response to a temperature change amount being greater than or equal to a predetermined value during the imaging device capturing a plurality of images at a predetermined time interval.

Abstract: This disclosure relates to systems and methods for executing a caching procedure for a web cache that is utilized by an electronic platform storing a plurality of clusters. The caching procedure may comprise retrieving a priming cutoff parameter that identifies a timeframe, utilizing the priming cutoff parameter to identify a subset of clusters that have been added or updated within the timeframe, and priming the web cache with content associated with the subset of clusters. The content in the web cache can be transmitted in response to receiving requests for the content. Other embodiments are disclosed herein.
