An analog-to-digital conversion circuit includes a convertor configured to perform a first comparison operation for sensing a noise based on a reset signal and to perform a second comparison operation for sensing raw data to output data which is obtained by removing the noise from the raw data, and a ramp voltage generator configured to generate a ramp voltage used for the first comparison operation and the second comparison operation and to output the ramp voltage to the convertor. The ramp voltage generator includes a first current source for supplying a bias current for generating the ramp voltage in response to a first control signal, a second current source for supplying a boost current for generating the ramp voltage in response to a second control signal, and a generation circuit for generating the ramp voltage based on the bias current and the boost current.

Systems and methods for moving image capture from video displays are disclosed. In particular, systems and methods for synchronizing display and camera timing so as to reduce or eliminate artifacts appearing in the captured moving images due to unsynchronized interaction between camera shutter/exposure timing and the timing of the display control signal.

An image capturing device capable of intermittent image capture, based on a predetermined given timing, to acquire multiple first images includes a detecting unit, an acquiring unit, and a setting unit. The detecting unit detects at least either a zooming operation or a panning operation that is performed when an image of a subject is captured. The acquiring unit causes a second image to be acquired in accordance with the zooming operation or the panning operation when at least either the zooming operation or the panning operation has been detected. The setting unit sets the second image as an image corresponding to at least one frame forming a time-lapse motion picture when at least either the zooming operation or the panning operation has been detected. The second image is acquired at a different timing from the given timing for acquiring the first images.
