Abstract

An electronic apparatus includes: a temperature measurement section that measures a temperature of a heat generation source generating heat by consuming power or a temperature of an inner position of a casing of which the temperature changes due to the heat generation of the heat generation source; and an environmental temperature calculation section that calculates a temperature which is calculated using a predetermined relational equation that is different in accordance with a model from a difference between a first temperature measured by the temperature measurement section at a point in time when the heat generation source starts consuming a predetermined amount of power and a second temperature measured by the temperature measurement section at a point in time after the passage of a predetermined period from the start of consumption of a predetermined amount of power by the heat generation source as an environmental temperature in an environment where the casing is placed.

Description

technical field [0001] The present invention relates to electronic devices and methods of controlling electronic devices, and more particularly, the present invention relates to portable electronic devices such as digital cameras, cellular phones, or portable audio players and methods of controlling such electronic devices. Background technique [0002] In portable electronic devices such as digital video cameras, digital cameras, portable phones, or portable audio players, it is very important to achieve both enhanced performance and reduced size in order to meet users' needs. In addition, products in which separate devices are integrated with each other are being commercialized as size reduction advances. An example of such a product is a product in which a digital camera, a portable audio player, and a cellular phone are integrated with each other. [0003] However, enhancement of the performance of electronic devices means an increase in the amount of data processed by ...
