IMAGE PROCESSING DEVICE AND IN-VEHICLE CONTROL DEVICE

An image processing device includes: an input unit that acquires each photographed image from a plurality of cameras installed in a vehicle; a photographing state detection unit that detects whether a malfunction has occurred in a photographing state of each of the photographed images; a likelihood calculation unit that calculates, for each of the cameras, a likelihood indicating a degree of malfunction of the photographing state on the basis of each of the photographed images; and a likelihood update unit that updates the likelihood to a new likelihood on a basis of a determination obtained by integrating the likelihoods for each of the cameras calculated by the likelihood calculation unit, in which the likelihood updated by the likelihood update unit is outputted as the likelihood for each of the cameras.
