Patent ID: 8564610

Claim:
An in-vehicle device comprising: a measured value acquisition unit, which acquires measured values that vary depending on conditions of a vehicle as first and second measured values; an image storage unit, which stores kinds of basic images; an image generation unit, which generates an image for display use by synthesizing at least two of the kinds of basic images stored in the image storage unit to represent the first and second measured values acquired by the measured value acquisition unit, and generates the image for display use by transparentizing some areas corresponding to the acquired first and second measured values of at least one of the given basic images among the kinds of basic images, and thereby overlapping the transparentized areas on an image other than the given basic image; and an image display unit, which displays the image for display use generated by the image generation unit, wherein: the image storage unit stores: a first basic image showing the case where the first and second measured values are both the minimum values; a second basic image showing the case where the first measured value is the minimum value and the second measured value is the maximum value; a third basic image showing a case where the first measured value is the maximum value and the second measured value is the minimum value; and a fourth basic image showing the case where the first and second measured values are both the maximum values; and the image generation unit uses: the first, third and fourth basic images for creating the image for display use, when the first measured value is larger than the second measured value; and the first, second and fourth basic images for creating the image for display use, when the first measured value is not larger than the second measured value.
