Abstract: A detection apparatus includes a first distance measuring unit that includes a light source configured to emit light having irradiation intensity changeable for each of a plurality of detection areas, the first distance measuring unit configured to emit the light to the detection area and to acquire first distance information to the detection area using reflected light from the detection area, a second distance measuring unit configured to acquire second distance information to the detection area using image information, and a determining unit configured to determine the irradiation intensity based on the second distance information.

Abstract: A programmable signal processing apparatus comprises a plurality of ALUs and a control unit that performs control for configuring a targeted circuit based on received information. The plurality of ALUs include a first type of ALU with one input and multiple outputs and a second type of ALU with two inputs and one output. The first type of ALU delays input data and outputs a plurality of pieces of data with different delay amounts. The second type of ALU generates one or two delayed data and performs an operation on the one or two data. The second ALU does not delay the one or two data in a state where supply of a clock signal to a plurality of registers in the second ALU is cut off.
