Abstract: An electronic device configured to be worn by a user includes a light-emitter that emits light onto skin of the user, a light-receiver provided at a position for enabling reception of the light reflected by the skin of the user when the electronic device is being worn by the user and the light-emitter is emitting the light, and a processor. The processor performs a skin determination for, on the basis of a quantity of light received by the light-receiver, determining whether the skin of the user satisfies a predetermined darkness condition, performs a being-worn determination for, on the basis of at least the quantity of light received by the light-receiver, determining whether the user is wearing the electronic device, and does not perform the being-worn determination in response to determining in the skin determination that the darkness condition is satisfied.

Abstract: An electronic device includes a sensor unit, a first CPU, and a second CPU. A first management unit functioning in the first CPU manages first information related to cumulative information acquired by the sensor unit. A second management unit functioning in the second CPU manages second information related to the cumulative information. One of the first management unit and the second management unit outputs a corresponding one of the first and second information related to the cumulative information managed by the one management unit to the other management unit according to switching of an operating state of the first CPU, and the other management unit continues management of the corresponding other of the first and second information related to the cumulative information based on the corresponding one of the first and second information related to the cumulative information output from the one management unit.

Abstract: An electronic device includes a sensor unit, a first cumulative value management unit, and a second cumulative value management unit. The sensor unit acquires cumulative information. The first cumulative value management unit functions in a first CPU, and manages the cumulative information. The second cumulative value management unit functions in a second CPU, and manages the cumulative information. One management unit of the first cumulative value management unit and the second cumulative value management unit outputs the cumulative information managed by the one management unit to the other management unit according to switching of an operating state of the first CPU, and the other management unit continues management of the cumulative information on the basis of the cumulative information output from the one management unit.

Abstract: An imaging apparatus, including, an imaging section, a gain adjustment section to adjust gain values of an R component or a B component, an information obtaining section to obtain information about a first photographing environment of the image after an adjustment, a first judgment section to judge whether the first photographing environment in the obtained information and a second photographing environment to which the gain adjustment section is to adjust the gain values of the R component or the B component, are different from each other, a gain re-adjustment section to re-adjust at least one of the gain values of the R component and the B component to be suppressed when judged that the first photographing environment and the second photographing environment are different from each other, and an image recording section to record an image obtained by performing a color adjustment by using a re-adjusted gain value.
