Embodiment Construction

[0024] Hereinafter, with reference to the drawings, a camera to which the present invention is applied will be used to describe preferred embodiments. The camera of a preferred embodiment of the present invention is a digital camera. The camera has an imaging section, and the subject image is converted into image data by the imaging section. Based on the converted image data, the subject image is displayed in a live view on a display section arranged on the back of the main body. The photographer determines the composition and shutter timing by observing the live view display. At the time of the release operation, the image data of the still image is recorded in the recording medium. When the reproduction mode is selected, the image data recorded on the recording medium can be reproduced and displayed on the display unit.

[0025] In addition, the camera operates by being supplied with power from the main power supply. A constant voltage is supplied from the variable voltage c...

Abstract

The invention provides an image device and an imaging method that prevent image degradation due to noise, and that do not impair usability. The imaging device of the present invention operates with supply of power from a main power supply, and comprises a CMOS image sensor (22) for forming a subject image and outputting image data, a DC / DC converter (29a), supplied with power from the main power supply, for converting to a designated voltage based on control signals, and outputting the designated voltage, a LDO regulator (29b) that receives output of the DC / DC converter (29a) and supplies a constant voltage signal to the CMOS image sensor (22), an input section (switch section (28)) for setting operating mode of the imaging device, obtaining a voltage value input to the DC / DC converter (29a) in accordance with operating mode that has been set by the input section, and designating an output voltage to the DC / DC converter (29a).

Description

Technical field [0001] The present invention relates to a photographing device and a photographing method, and in detail, to a photographing device and a photographing method that provide a constant voltage from a main power source to an imaging unit via a power supply unit. Background technique [0002] The imaging element photoelectrically converts the optical image and outputs an image signal. However, as the ambient temperature of the imaging element becomes high, imaging noise is generated in the image and the image quality is degraded. In order to prevent this imaging noise, for example, in Japanese Laid-open Patent No. 2006-140733 (hereinafter referred to as Patent Document 1), when a predetermined temperature is exceeded, it is possible to turn off the power, shift to a specific mode, turn off the CCD clock, or drive Cooling device. Summary of the invention [0003] The problem to be solved by the invention [0004] According to Patent Document 1, the temperature is lowere...
