The ultrasonic measurement apparatus has a reception processing unit that receives, via an ultrasonic element array having a plurality of channels, an ultrasonic echo relating to an ultrasonic wave transmitted toward an object, as a reception signal for each channel, an error detection unit that performs error detection for each channel, a signal processing unit that performs weighted addition of a reception signal for each normal channel other than an error channel for which an error was detected, with a weight that depends on the reception signal for the normal channel, and an image generation unit that generates an image based on a signal obtained from the weighted addition..

Solid-state imaging device


According to one embodiment, a solid-state imaging device includes an image sensor including a valid pixel area having valid pixels and a light-blocking pixel area having light-blocking pixels to generate an image signal; and a clamp circuit that detects an overflow of a signal charge and executes a black level signal processing for the image signal using a parameter. The clamp circuit detects the overflow using an integration value of the signals of the light-blocking pixels integrated in a direction from the light-blocking pixel area to the valid area, and sets the parameter generated from the output signals of the light-blocking pixels substantially not influenced by the overflow based on a result of the detection..

Method and controlling interchangeable lens system camera


A method of controlling an accessory device which is connected with a body unit of an interchangeable lens system camera is described. The method includes: receiving identification information of a first device from the first device through a first communication path that passes through a digital signal processing unit of the accessory device; generating combination information by adding identification information of the accessory device to the identification information of the first device; transmitting the combination information to a second device through the first communication path; and when receiving a switching signal from the second device, switching the first communication path to a second communication path that does not pass through the digital signal processing unit of the accessory device..

Image signal processing circuit, image signal processing method and display apparatus


An image signal processing circuit includes a storage unit that stores a number of set values, which determine correction values for performing correction of color temperature of an input digital image signal, that is less than a number of gradations, and a computation unit that calculates correction values for performing the correction of color temperature on the basis of the set values for gradations for which a set value is stored in the storage unit, and on the basis of post-correction gradation values of gradations for which a set value is stored for gradations for which a set value is not stored in the storage unit.. .
