Abstract

An information recording device in which low-noise and clear image or audio information can be recorded by stopping the generation of a carrier in an oscillation section of wireless communication device during an imaging or sound recording process. The information recording device includes an electronic camera having recording unit which can record at least either image or audio information; wireless communication unit for transmitting the information to external equipment through wireless communication; a transmitting section including an oscillation section for generating a carrier used for the wireless communication; and imaging/image processing control unit for controlling the generation and stop of the carrier; and the imaging/image processing control unit causes the oscillation section to stop the generation of a carrier at least for a period from the time when the image or audio information is captured to the time when the image or audio information is recorded, low-noise and clear image or audio information can be recorded.

Claims

1. An information recording device, comprising:

a recorder which can record at least either image or audio information;

a wireless communication device for transmitting said information to external equipment through wireless communication;

a carrier generating section for generating a carrier for said wireless communication device; and

a controller for controlling the generation and pause of said carrier,

wherein said controller causes said carrier generating section to pause the generation of the carrier when the information recorder receives an instruction to capture an image, and the controller causes the carrier generating section, which is transmitting the at least image or audio information, to pause at least for a period from the time when said image or audio information is captured to the time when said image or audio information is recorded, and

wherein the controller pauses only a carrier oscillation section of the carrier generating section while a clock oscillator of the carrier generating section is active.
