Abstract: A gate system control device is a gate system control device configured to control a gate system having an exit gate, and includes a first sensor, a second sensor, and a controller. The first sensor senses that a passport of a person who is in the gate system is placed on a placement region. The second sensor senses that the person is moving. The controller controls the gate system. When the first sensor senses that the passport is placed on the placement region and the second sensor senses that the person is moving to the exit gate, the controller causes the gate system to execute processing for notifying the person.

Abstract: A placement detection system includes: a placement table; an imaging device that images an object placed on the placement table to generate an input image; and a control device. The control device generates a first binarized image for the input image based on a first threshold value and determines whether the object is placed in a predetermined placement orientation. The control device changes a threshold value for a target pixel to a second threshold value higher than the first threshold value when the object is determined to be placed in the predetermined placement orientation, the target pixel being sandwiched between pixels having pixel levels lower than or equal to the first threshold value and has a higher pixel level than the first threshold value in a first region, generates a second binarized image for the target pixel based on the second threshold value, and detects a shape of the object.

Abstract: An extraction unit determines whether, in a display area of a display unit in which content data obtained from an acquisition unit are displayed, there is a character area in which an area occupied by a character has a proportion greater than a predetermined value. Based on color information of the character in an area which is determined to be the character area by the extraction unit, a setting unit sets a target color temperature when the content data is displayed. A converter changes an original color temperature of the content data to the target color temperature, based on the target color temperature set by the setting unit.

The signal processing device includes a calculator, a setting unit, and a converter. The calculator sets a ratio to a display area of a first area in which a character is mainly displayed in the display area of the content data, and sets a ratio to the display area of a second area in which an object other than character such as an image is mainly displayed. The setting unit sets a target color temperature based on the ratio set by the calculator. The converter changes a current color temperature of the content data to the target color temperature set by the setting unit.
