An ultrasonic module includes a reception circuit adapted to receive a reception signal from an ultrasonic device, which receives an ultrasonic wave, to generate an echo signal, switching power supplies driven with a predetermined switching cycle, and adapted to supply the reception circuit with electrical power, and a phasing addition circuit adapted to perform an addition process on a first echo signal output when driving the reception circuit at a first drive timing in the switching cycle, and a second echo signal output when driving the reception circuit at a second drive timing delayed as much as a half cycle of a switching noise in the switching power supplies from the first drive timing.

Ultrasonic module, ultrasonic apparatus, and method of controlling ultrasonic module

Provided are an ultrasonic measurement apparatus, an ultrasonic imaging apparatus and an ultrasonic measurement method that achieve an increase in processing speed together with an increase in resolution and are user friendly. An image is generated by adding together, with a weight having a fixed value, reception signals obtained by ultrasonic echoes being received by an ultrasonic element array, and an area of interest is set within the area in which the generated image is to be displayed. When an area of interest is acquired, the reception signals received by the ultrasonic element array are added together with weights that depend on the reception signals, with respect to data forming the basis of the image to be displayed in the area of interest, and image generation is performed.

Ultrasonic measurement apparatus, ultrasonic imaging apparatus, and ultrasonic measurement method

A printing system that transfers an image composed of pixels of a first resolution, includes a client and a printing apparatus. The client includes a determining unit that, for a pixel block that is of a size of a pixel of a second resolution that is lower than the first resolution, determines whether or not the pixel block is homogenous on the basis of a difference in color information for a target pixel of the first resolution included in the pixel block; an image-data-for-transfer creating unit that creates image data for transfer by changing pixels of the first resolution included in a pixel block that has been determined to be homogenous from the first resolution to the second resolution; and a transmitting unit that transmits the image data for transfer. The printing apparatus includes a receiving unit that receives the image data for transfer and a high-resolution-image-data creating unit that creates image data representing an image composed of pixels of the first resolution by changing pixels of the second resolution in the image data for transfer from the second resolution to the first resolution.

Printing system, printing apparatus and image-printing method for suppressing image quality degradation

There is provided a method of manufacturing an electro-optical device from a large substrate that is cut into a plurality of first substrates having a chip shape. In the electro-optical device, second substrates of a chip shape are bonded to the first substrates. The method includes adhering a large glass substrate to approximately an entire surface of the large substrate opposite to a surface to which the second substrates are bonded; and cutting both the large substrate and the large glass substrate into first substrate units.
