Description

This invention relates to electronic equipment, a control method for electronic equipment, a program, and a storage medium. Recent imaging devices have improved automatic exposure, autofocus performance, and subject detection capabilities, making it possible to shoot most subjects in automatic mode. However, depending on the shooting scene, there are times when it is better to set the shooting conditions individually, and in such cases, the ability to change settings immediately is required. Patent Document 1 proposes an imaging device characterized by a setting means for setting multiple setting items, a designation means for specifying the items to be registered from among the multiple setting items, a registration control means for registering as registered shooting conditions, and a function that, in response to a user's call operation, recalls the registered shooting conditions and generates new shooting conditions that reflect them. This enables immediate setting changes by allowing the user to register shooting settings in advance and recall them.

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. ●Configuration of the Digital Camera Figures 1(a) and 1(b) show an external view of a digital camera 100 as an example of a device (electronic device) to which the present invention can be applied. Figure 1(a) is a front perspective view of the digital camera 100, and Figure 1(b) is a rear perspective view of the digital camera 100. In Figure 1, the display unit 28 is a display unit provided on the back of the camera that displays images and various information. The touch panel 70a can detect touch operations on the display surface (operation surface) of the display unit 28. The viewfinder-external display unit 43 is a display unit provided on the top surface of the camera that displays various camera settings, including shutter speed and aperture. The shutter button 61 is an operation unit for giving shooting instructions. The mode switching switch 60 is an operation unit for switching between various modes. The terminal cover 40 is a cover that protects the connector (not shown) that connects the connection cable to an external device to the digital camera 100. The main electronic dial 71 is a rotating control element, and by rotating it, settings such as shutter speed and aperture can be changed. The power switch 72 is a control element that switches the power of the digital camera 100 ON and OFF. The sub-electronic dial 73 is a rotating control element that allows movement of the selection frame and image advancement. The cross key 74 is a cross key control element (four-way key) with push buttons that can be pressed in four directions: up, down, left, and right. The operation corresponding to the direction pressed on the cross key 74 is possible. The SET button 75 is a push button and is mainly used to confirm selection items. The video button 76 is used to instruct the start and stop of video recording. The AE lock button 77 can be pressed in shooting standby mode to fix the exposure state. The zoom button 78 is a control button for turning the zoom mode ON and OFF in the live view display of the shooting mode. By turning on the magnification mode and operating the main electronic dial 71, the live view image can be enlarged or reduced. In playback mode, it functions as a magnification button to enlarge the playback image and increase the magnification ratio. The playback button 79 is an operation button that switches between shooting mode and playback mode. By pressing the playback button 79 while in shooting mode, the camera switches to playback mode, and the latest image recorded on the recording medium 200 can be displayed on the display unit 28. Pressing the menu button 81 displays various configurable menu screens on the display unit 28. The user can intuitively make various settings using the menu screen displayed on the display unit 28, the directional keys 74, the SET button 75, or the multi-controller (MC) 65. The MC 65 can accep
