摘要:
A range finding apparatus includes a light emission unit including a light source and a light source driver, a light detection unit, and circuitry. The light source driver supplies a plurality of drive pulses having different pulse width at different time periods. The light detection unit receives the light emitted from the light emission unit and then reflected from an object. The circuitry calculates a range to the object based on a time difference between one time point when a pulse light is emitted from the light source and another time point when light reflected from the object is received by the light detection unit. One of the drive pulses set with a smaller pulse width is set with a sine wave pattern, and another one of the drive pulses set with a greater pulse width is set with a rectangular wave pattern.

A range-finding device including a light-emitting device, an imaging unit, a calculator, and a controller. The image unit receives pulsed light reflected from an object within the space for a plurality of time periods in a time-division manner, electrically converts the pulsed light into an electrical signal, and accumulates electric charge of the electrical signal for each of the plurality of time periods. The calculator calculates a time difference between emission of the pulsed light and reception of the pulsed light reflected from the object based on the electric charge accumulated for each of the plurality of time periods and determine a distance to the object based on the time difference. The controller controls the timing of reception of the pulsed light for each of the plurality of time periods at the imaging unit according to an intensity of the pulsed light reflected from the object.

摘要:
Dot patterns formed by two different half-tone processes of the plurality of tone processes for each color of CMYK and formed with/without the presence and absence of transparent toner overlap are created and test patches obtained by collecting the dot patterns are printed. The printed test patches are read to generate image data, and tone correction arithmetic is performed on the basis of the image data. Concentration in the case of the presence of transparent toner in a different half-tone process is predicted based on the dot patterns with the transparent toner overlap in the test patches and concentration in the case of the absence of transparent toner in a different half-tone process is predicted based on the dot patterns without the transparent toner overlap in the test patches. The tone correction arithmetic is performed based on the predicted values.
