  • Publication number: 20260146844
    Abstract: According to an aspect, a detection device includes: a light source part in which point light sources are arranged; a planar optical sensor in which optical sensors are arranged; an object placement member; and a control circuit. The planar optical sensor has detection areas corresponding to an arrangement of the point light sources. Each detection area includes more than one optical sensor. When predetermined conditions are satisfied, a process, in which luminance of the point light source before or after luminance change is set as adjusted luminance of the point light source, is individually performed for each combination of the point light sources and the detection areas; and the predetermined conditions are that one of two output levels of each detection area obtained before and after changing the luminance of each point light source is higher than a threshold, and that the other thereof is lower than the threshold.

  • Patent number: 12484129
    Abstract: A detection apparatus includes a sensor, a detection circuit, and a light source configured to emit light in a first color, a second color, and a third color. The detection circuit acquires a first output, a second output, and a third output that are outputs of the sensor corresponding to a period when the light in the first color is emitted, a period when the light in the second color is emitted, and a period when the light in the third color is emitted, respectively. The detection circuit adjusts at least two or more of the first, second, and third outputs based on adjustment coefficients derived so as to equalize a fourth output, a fifth output, and a sixth output. The fourth, fifth, and sixth outputs are outputs obtained when the sensor is directly irradiated with the light in the first, second, and third colors from the light source, respectively.

  • Publication number: 20250231099
    Abstract: According to an aspect, a detection device includes: a sensor panel that has a detection area in which optical sensors are arranged; a light source unit comprising multiple types of light sources; a member on which an object to be detected is to be placed; and a detection circuit configured to obtain outputs of the optical sensors. The light sources configured to emit light in different colors are configured not to be turned on simultaneously but to be turned on in different periods. An exposure time when the optical sensor detects light differs between the light sources that emit light in different colors. The output of the optical sensor under conditions where the object to be detected is not placed falls within an output range corresponding to a predetermined target value, regardless of the color of the light emitted by one of the light sources that is turned on.
