To provide a device and a method of analyzing a change in the degree of focusing between a current image and a past image and outputting display data capable of identifying a change in the degree of focusing to a display unit. A focusing-degree change analysis unit that analyzes a change in a degree of focusing between a current image output from an image sensor and a past image output from the image sensor before the current image is output and a display control unit that generates display data enabling checking of a focusing-degree change state from the past image in units of pixel regions of the current image by using an analysis result of the focusing-degree change analysis unit are provided. Pixel classification information indicating which of (a) pixel approaching focusing, (b) pixel out of focusing, and (c) pixel with no change in the degree of focusing each pixel corresponds to is generated and output in units of pixels.

An electronic device having a first surface on which a first lens and a second lens with a wider angle than the first lens is arranged and a second surface on which at least a third lens is arranged, the electronic device comprising control means for controlling a captured image of the first lens to be displayed in response to issuing an instruction to display a captured image of a lens on the first surface, and controlling a captured image at a second field angle wider than the first field angle to be displayed in response to issuing an instruction to display a captured image of a lens on the second surface.

An apparatus includes an operation ring including first and second tooth portions, a first unit including an emitting portion that emits light to the first tooth portion and a receiving portion that receives emitted light passing through slits of the first tooth portion, and a second unit including an emitting portion that emits light to the second tooth portion and a receiving portion that receives emitted light passing through slits of the second tooth portion. Rotation of the ring is detected based on detection results by the first and second units. The ring has grooves formed at a first period in a circumferential direction thereof, and between the first and second tooth portions in a direction parallel to a rotation axis of the ring. The apparatus further includes a sliding member that is biased in a radial direction of the ring and slides over the grooves as the ring rotates.

A control device controls an image capturing device installed in a wearable device. A display device is capable of communicating with the control device. The control device is configured to: cause the display device to display a plurality of candidate images corresponding to images of a subject captured with different exposure conditions; detect a selection of one of the candidate images; and cause the image capturing device to capture an image of the subject with an exposure condition corresponding to the one of the candidate images as selected.

An electronic device moves a selected position on a display. In a first case, in which the selected position is specified on a basis of the line-of-sight input but a first operation is not performed to an operation unit, the electronic device displays an item indicating a range of a first size, in a second case, in which the selected position is specified on a basis of the line-of-sight input and the first operation is performed to the operation unit, the electronic device displays an item indicating a range of a second size, which is smaller than the first size, in the first case, an object is selected in response to a second operation on a basis of a predetermined condition, and in the second case, an object is selected in response to the second operation without being on a basis of the predetermined condition.

An electronic apparatus including a first lens and a second lens at a first side, the second lens having a angle of view different from that of the first lens, includes a switching unit configured to switch first imaging via the first lens and second imaging via the second lens, and a control unit configured to control display of items corresponding to a plurality of respective imaging modes, wherein the control unit is configured to, in a case where the second imaging is being performed, control display of a first item and a second item in different display modes, the first item corresponding to an imaging mode that enables the first imaging and the second imaging, the second item corresponding to an imaging mode that enables the first imaging and disables the second imaging.

A first image capturing unit (203 to 205) configured to capture an image using a lens placed on a first surface, a second image capturing unit (201 and 202) configured to capture an image using a lens placed on a second surface, the second image capturing unit being configured to switch to first image capturing using a first lens and second image capturing using a second lens with a wider angle than an angle of view of the first lens, and a control unit configured to perform control to, during the image capturing by the second image capturing unit, in response to a user operation for changing from a still image capturing mode to a moving image capturing mode, switch to the moving image capturing mode and also switch from the first image capturing using the first lens to the second image capturing using the second lens, are included.
