Abstract: Image processing is made efficient. An image processing apparatus according to an embodiment includes a line memory, a plurality of pipelines, and a line memory control circuit that controls data reading from the line memory to processing units. The processing unit includes a first operator that performs a first arithmetic operation, a second operator which performs a second arithmetic operation based on first intermediate data based on an arithmetic operation result of the first operator and which calculates second intermediate data according to the first intermediate data of when peripheral pixels are sequentially changed, third operators which perform a third arithmetic operation based on the first intermediate data and which calculate third intermediate data according to the first intermediate data of when the peripheral pixels are sequentially changed, and delay elements that delay the third intermediate data.

Abstract: A mobile object control system has an SfM unit detecting distance to an object imaged by a monocular camera by using the SfM algorithm, a first-stop-position output unit outputting a first stop position, a second-stop-position calculating unit calculating a second stop position closer than the first stop position, and a control unit controlling travel of a mobile object. The control unit controls the mobile object so as to stop at the second stop position. When a predetermined starting condition is satisfied, the control unit controls the mobile object so as to start. The SfM unit detects the distance to an object by using an image captured by the monocular camera after the mobile object starts. When a result of detection of the distance of the object by the SfM unit is obtained, the control unit uses the detection result for control of the travel.
