A measuring device includes a first light receiving element that receives measurement light and outputs a first output value, and a second light receiving element that receives the measurement light and outputs a second output value which is different from the first output value. A weighted composition is performed on the first output value and the second output value.

Measuring device, electronic apparatus, and measuring method

A measuring apparatus includes a carriage on which an imaging control section that controls imaging of an object is mounted, a movement control section that moves the carriage relative to the object, an image processing section that acquires image information, a first signal line that connects the imaging control section and the movement control section to each other, and a second signal line that connects the imaging control section and the image processing section to each other. A control signal is transmitted over the first signal line, and a data signal is transmitted over the second signal line.

Measuring apparatus and printing apparatus

An image processing device is adapted to be provided with a photographing device configured to generate image data by photographing a print pattern and to output the image data, vertical synchronization signals, and horizontal synchronization signals. The image processing device includes: a first processor configured to, based on the synchronization signals, determine occurrence of abnormalities of the image data that is input, a memory including two storage areas, and a second processor. The second processor is configured to perform for each frame of the image data an addition process while exchanging a first storage area and a second storage area different from the first storage area of the memory with each other.

Image processing device, printing apparatus, and control method

An imaging device outputs imaging data captured with a predetermined exposure time, and a brightness determination unit determines whether the brightness of the imaging data is within a predetermined range. Re-imaging is performed with the exposure time changed when the brightness of the imaging data is not within the predetermined range. The re-imaging is performed with the exposure time lengthened when the brightness of the imaging data is less than a determination value, and the re-imaging is performed with the exposure time shortened when the brightness of the imaging data is saturated.

Colorimetry method, colorimetry device, spectral measurement method, spectral measurement device and electronic apparatus

A spectrometry apparatus includes a wavelength variable interference filter emitting light of various predetermined wavelengths; a roll shutter imaging element having pixels accumulating electric charges when exposed to light, and forming one frame by photodetection for each pixel block including pixels with a predetermined time delay for each pixel block, in which the imaging element accumulates electric charges in a photodetection period, and outputs a detection signal in response to the accumulated electric charges in a non-photodetection period; and a spectroscopic controller controlling the wavelength change driving of the emitted light of the wavelength variable interference filter. For the one frame, the spectroscopic controller starts the wavelength change driving at an end timing of the photodetection period of a final pixel block for which the photodetection process is performed at the end.

Optical module, electronic apparatus, and method of driving optical module

An optical module includes a wavelength variable interference filter that selects light of a predetermined wavelength from incident light, and can change the wavelength of emitted light; a global shutter imaging element that accumulates electric charges while being exposed to the emitted light, and outputs a detection signal in response to the accumulated electric charges; an imaging element controller for setting a photodetection period during which the electric charges are accumulated in the imaging element, and a standby period during which the electric charges accumulated in the imaging elements are reset; and a spectroscopic controller for controlling the wavelength change driving of the emitted light. The imaging element controller sets the duration of the standby period to a minimum drive time for changing the wavelength or greater. The spectroscopic controller starts the wavelength change driving at the start of the standby period.
