Embodiment Construction

[0037] In order to improve the output image quality of the image device when it is charging, the present invention provides an influencing device. When the image device is in the state of charging and needs to work, the temperature of the image sensor detected by the temperature sensor is obtained to control the charging current. By reducing the charging current The method reduces the influence of thermal noise on the output image quality of the image sensor. The imaging device in the embodiment of the present invention is not limited to a camera, and the term "imaging device" in the embodiment of the present invention may include a digital imaging device such as a camera, a video camera, and a video camera with a photographing and / or video recording function. The embodiments of the present invention are applied to a state where an imaging device is charging and needs to work, for example, a camera is charging while taking pictures.

Abstract

The invention discloses an image device and a charging control method thereof. The image device comprises a microprocessor, a temperature sensor, an image sensor and a battery module; the temperature sensor is used for detecting the temperature of the image sensor; the microprocessor is used for obtaining a temperature value of the image sensor detected by the temperature sensor when external current input is detected and when the image sensor is in a working state; and when the temperature value is greater than a first threshold, the charging current of the battery module is reduced to adjust the temperature of the image sensor. When the image device provided by the embodiment of the invention is in a charging and working state, the temperature of the image sensor detected by the temperature sensor is obtained to control the charging current, the influence of heat noise to the quality of the output image of the image sensor is reduced by reducing the charging current, and thus the quality of the output image is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of electronic technology, and in particular, to an image device and a charging control method thereof. Background technique [0002] As a device for recording people's living conditions, imaging devices (such as cameras and video cameras) have become more and more indispensable. At present, when the low voltage of the imaging device needs to be charged, the charging current is equal to the target current configured by the charging management chip (usually the maximum charging current that the system can withstand). Since the target current is usually relatively large, there will be a problem on the battery and the charging circuit. heat, which in turn leads to an increase in the overall temperature of the imaging device. The noise density and noise brightness of the output image (or image) of the imaging device are positively correlated with the temperature of the photosensitive element CMOS (Co...
