An arithmetic operation device executes a test using a partially reconfigurable programmable logic unit, the programmable logic unit includes a test target circuit which is a user circuit, and a non-test circuit which is a user circuit which is not the test target circuit, and the arithmetic operation device includes a configuration control unit which causes the programmable logic unit to form, by partial reconfiguration, a test partition unit which separates the test target circuit and the non-test circuit, and a partition control unit which controls the test partition unit to test the test target circuit.

Arithmetic operation device, testing method

The present invention provides a control device capable of controlling a cooling device in response to temperature changes due to external factors. The present invention is a control device for controlling a cooling device for cooling an object to be cooled, said control device being characterized by comprising: a temperature change prediction information acquisition unit for acquiring temperature change prediction information, which is information concerning temperature changes of the object to be cooled; a temperature change prediction unit for predicting the temperature changes of the object to be cooled on the basis of the temperature change prediction information acquired by the temperature change prediction information acquisition unit; and a control unit for controlling the cooling device for cooling the object to be cooled, such control carried out on the basis of the prediction results according to the temperature change prediction unit.

Control device for cooling device

The present invention provides a camera device capable of quickly processing image data while suppressing bus traffic. In the present invention, an image memoryis connected to a memory busand stores a right source imageand a left source image. A memory access managementis connected to the memory busand to an internal bus, reads the right source imageand the left source imagefrom the image memoryvia the memory bus, and outputs the read right source imageand the left source imageto the internal bus. Processing unit A, processing unit B, and processing unit Care connected to the internal busand process the image data output to the internal bus

Camera device

In order to provide a stereoscopic imaging apparatus that can acquire, in a case in which a brightness different is large, parallax information containing a parallax image in all image capturing frames, provided are an image acquisition unit that acquires a first image and a second image different from the first image in exposure time, a gain and offset correction unitthat corrects brightness of one of the acquired first and second images, a parallax calculation unitthat calculates parallax from one of the images corrected by the brightness correction unit and the other of the images and outputs a parallax image and parallax information, and a combination image generation unitthat combines the acquired first and second images together to generate a combination image and outputs the generated combination image.

Stereoscopic imaging apparatus

The present invention inexpensively executes fault diagnosis in real time without obstructing an original image-processing function even while driving. To this end, this in-vehicle-camera image processing device has: one or more camera units capable of selectively switching between a captured image and a test image and outputting the same; an image-processing unit for subjecting a captured image outputted by the camera units to image processing; and a fault diagnosis unit for subjecting the camera units to fault diagnosis, on the basis of the test image outputted by the camera units. In addition, the image-processing unit determines whether or not a fault diagnosis is possible on the basis of the image-processing results, and when fault diagnosis is determined to be possible, outputs diagnosis instruction information to the fault diagnosis unit. The in-vehicle-camera image processing device is characterized in that upon receiving input of the diagnosis instruction information from the image-processing unit, the fault diagnosis unit outputs, to the camera units, an image-selection-instruction signal for switching the image outputted by the camera units from the captured image to the test image.
