Abstract: There is provided an optical sensor including an SPAD pixel array, multiple counters and a processor. The multiple counters count photon events of the SPAD pixel array to output an event-based vision sensor (EVS) frame per EVS period. The processor determines an index state of each pixel of the SPAD pixel array by comparing a counting value of each pixel respectively at a predetermined number of checking points with two predetermined thresholds, and calculates an index change of the index state associated with each pixel between adjacent EVS frames. The processor further changes the EVS period and/or adds a count offset to the counting value of each pixel to improve sensitivity of the event-based vision sensor.

Abstract: An apparatus is provided for measuring far-field luminous intensity and color characteristics of a light source that includes a lamp test location for receiving a lamp for testing and a mirror positioned in a fixed light receiving position relative to the lamp test location and positioned in a fixed light transmitting position for reflecting a light beam from the lamp at a predetermined angle relative to the light receiving position. A measurement screen is positioned in a location relative to the mirror to receive the parabolically-condensed light image reflected from the mirror at the predetermined angle and a light detector is positioned to capture a light image reflected from the measurement screen. The light detector is configured to convert the reflected light image on the measurement screen to a digital signal and output the digital signal. A computer is configured for receiving and processing the digital signal corresponding to the reflected light image and calibrated for measuring luminous intensity according to an algorithm programmed in the computer.

Abstract: To mitigate undesirable outcomes due to crosstalk in an ambient light sensor reading resulting from light emission from an electronic display, statistics may be gathered to determine and compensate for the crosstalk. For example, the ambient light sensor may detect ambient light levels while the electronic display is temporarily paused to reduce or eliminate crosstalk between the light produced by the electronic display and the ambient light sensor. However, the ambient light sensor may retain charge from a previous light emission, creating back-emission crosstalk. The ratio of back-emission to front-emission (e.g., present light emission) may not be linear, and the degree of nonlinearity may vary with pixel value, color component, display brightness, temperature, and so on. As the ambient light sensor is affected by back-emission, compensation for the nonlinearity between the front-emission and the back-emission may be obtained to estimate the crosstalk induced on the ambient light sensor.

Abstract: An image forming apparatus includes a detection element and a hardware processor. The detection element includes a receiving section that receives a specific signal and an output section that outputs a predetermined output value based on the specific signal received by the receiving section. The hardware processor determines in accordance with a status of an output from the output section, a state of deterioration that leads to a state in which the detection element needs to be replaced.

Abstract: An optical sensing device is provided. The optical sensing device includes an optical sensing element and a detection circuit. The optical sensing element senses an incident photon and generates a sensing signal. The detection circuit detects a pulse width of the sensing signal, and generates a reset signal when the pulse width is larger than a threshold value. Thereby, the optical sensing device is reset according to the reset signal and a dynamic range of the optical sensing device under strong ambient light will be further improved.
