Vehicle information recording apparatus
First Claim
1. A vehicle information recording apparatus comprising:
- a first memory for recording information concerning a vehicle in a cyclic manner; and
a recording control section for recording the information in a predetermined range recorded on the first memory on a second memory in accordance with a predetermined condition,wherein the recording control section is supplied with electric power from a main power source section,wherein the vehicle information recording apparatus comprises an auxiliary power source section acting as a backup for electric power supply from the main power source section to the recording control section,and wherein the recording control section allows, in a case where electric power is supplied from the auxiliary power source section, part of the information in the predetermined range recorded on the first memory to be recorded on the second memory.

Abstract
A vehicle information recording apparatus which is capable of recording information to be recorded on a recording medium without fail even in a case where electric power is supplied in a limited quantity is provided. Under the circumstances where a signal indicative of a command to record the information of images taken by a camera is issued and a main power source'"'"'s power detection portion detects the absence of electric power supply from a vehicle power source, a CPU performs a second recording operation which differs from a first recording operation in a manner that a predetermined part of the image information stored in a second SD-RAM on a frame-by-frame basis can be recorded on a CF card by exploiting the electric power supply from a backup power source section.

6. A vehicle information recording apparatus comprising:
-
an inputting section for inputting image information provided from an image taking apparatus mounted in a vehicle; a first memory; a memory connecting section to which a second memory is attached detachably; a power detecting section for detecting a presence or absence of electric power supply from a main power source section mounted in the vehicle; a control section for effecting control in such a manner that the image information provided from the inputting section is temporarily stored in the first memory on a frame-by-frame basis in chronological order, and, upon a signal indicative of recording of the image information being issued, the image information stored in the first memory is recorded on the second memory attached to the memory connecting section; and an auxiliary power source section for supplying, when an interruption of power supply from the main power source section mounted in the vehicle is detected by the power detecting section, electric power to the first memory, the memory connecting section, and the control section, wherein the control section performs, under circumstances where a signal indicative of recording of the image information is issued and the power detecting section detects the presence of electric power supply from the main power source section, a first recording operation to record the image information stored in the first memory on the second memory successively in the order in which the frames were stored in the first memory, and wherein the control section performs, under circumstances where a signal indicative of recording of the image information is issued and the power detecting section detects the absence of electric power supply from the main power source section, a second recording operation, which differs from the first recording operation, to record at least part of the image information stored in the first memory on the second memory by exploiting electric power supply from the auxiliary power source section. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)
