摘要： A brightness level detector detects a brightness level of the digital imaging signal for each of the plurality of pixels. A shading detector sets a group of pixel regions distant from each other in a horizontal direction in the imaging element and then detects whether or not shadings are generated in the analog imaging signal based on a difference between the brightness levels of the group of pixel regions. A timing adjuster adjusts a phase of a peak sample pulse for detecting a peak level of the analog imaging signal, a phase of a reference sample pulse for detecting a signal level used as a reference in the correlated double sampling executed when the digital imaging signal is generated and a phase of a horizontal transfer pulse in the imaging element based on outputs of the brightness level detector and the shading detector.

摘要： A signal processing circuit generates an image signal by performing signal processing to an imaging signal obtained through a picked up optical system that includes a lens, a diaphragm, an image sensor, and a lens barrel. A main light source detector detects a main light source contained in a picked up image of the image signal. An estimated ghost generator generates an estimated ghost based on layout information of the main light source and the imaging optical system, and structural information of the lens barrel. A matching device extracts an estimated ghost image by searching the estimated ghost in the picked up image through pattern matching. A ghost subtractor subtracts the estimated ghost image from the picked up image.

摘要： An image coding method includes: a predictive pixel generation step of generating a predictive value from at least one surrounding pixel located near a compression target pixel; a code conversion step of code-converting the pixel data to generate a Gray code; and quantizing bit change information (exclusive OR) between the generated Gray code and a Gray code of the predictive value to a quantization value, to compress the pixel data. This prevents significant image quality degradation, so that high image quality can be achieved.

摘要： Coding processing performed by an image coding device (100) includes: processing (S133) of performing coding by leaving surplus bit(s), when the digit number B of binary data of the difference value between (a) a value of a to-be-coded pixel and (b) a prediction value is smaller than the predetermined bit number M; and processing (S133) of performing coding by using the surplus bit(s), when the digit number B is greater than M and there are the surplus bit(s). Pieces of coded data each having a predetermined coding amount are generated, by performing processing for each of consecutive T pixels so as to perform the coding processing for each of U pixels among the consecutive T pixels (S136).

摘要： An intended-usage judger judges an intended usage of an inputted digital imaging signal. A selector selects one or a plurality of signals to be inspected from a group of signals constituting the digital imaging signal based on a result of the judgment by the intended-usage judger.
